GPS modem. Leica modems. Garpy

Modern systems in the form of energy resources are increasingly using GSM-measures for data transmission, so you need to know the support of GSM-operators, which is why they saw the possibility of increasing the subscriber base of voice services. GSM-merezhі are characterized by infrastructure spread in all regions, high reliability, capability Swedish larynx and low vartisnimi characteristics.

TOV "Analytik-TS", Moscow

All current GPRS-modems will be based on GSM-modules from a number of foreign manufacturers. Simplicity of organization on their basis of access from a computer to the Internet creates a deceptive impression about the presence of folding in case of industrial systems(previousness on the computer Windows drivers and periodically hovering, yak require the involvement of an operator, do not fall into the vіchі). To check with the GSM module, you can use:

Functional controller of the lichnik, heat exchanger or concentrator;

Specialist (telecommunication) controller;

PZ, vbudovane in the GSM-module and take on all the tasks of maintaining the call stability.

With all types of control implementation, it is necessary to go through a thorny path to convert the GSM module to a full-time GPRS modem, which will ensure the operation of the robot in uninterrupted and unattended modes:

Systems that are working on the table, raptly fix problems and “hang” when switching to real objects, when changing the operator, - installed in a different region or increasing the amount of merezh;

It is clear that the necessary conditions for processing random situations, safety and security, testing solutions, the appearance of regional features of operators, supporting the work with dynamic IP-addresses, ensuring access to the modem and other measures.

It's crazy, there are organizations that can solve problems, which they blame, but is it really economical for big? We look at the complexity of the implementation to produce completed solutions with high functionality before they appear on the market. Їhnya varіst, insanely, trohi vishcha, but the price is for your own PnP (including and practice).

Let's try to formulate the main ways to GPRS-modems and in the world of the ability to wrap them.

Basic services to GPRS modems

Zagalni vimogi

Support for the main GSM services: GPRS/EDGE, CSD and SMS.

Interfaces for connecting to devices: RS-232С (including "three-wire" - RxD, TxD and GND), RS-485, Industrial Ethernet.

Structural features: mounting on a DIN rail, built-in primary life wire with extended ranges ~140...286 V / 45...55 Hz or =18...36 V, operating temperature range -40...+70° WITH.

GSM-antenna: it is necessary to ensure the possibility of connecting the external antenna, as it may be caused from the zone of the installation of the radio (for example, from the basement) to the zone of the connected radio reception.

Automatic insertion of the day

If the modem is enabled, automatically activate the installed GPRS / EDGE or CSD channel and, in certain cases, automatically generate SMS notifications at the time of the fault “down” on additional logic inputs (for example, when using sensors in a fire and security alarm).

Security of confidence

It is necessary to use the following methods for reserving transmission channels:

On the level of routing between operators GSM-call (two SIM-cards);

On the level of GSM-services - transfer from GPRS/EDGE to CSD or SMS notifications.

In the minds of periodic channel disruption without signaling the server and the client (for example, when APN servers are reconfigured from the GSM operator), the control of system freezes for the help of an independent watchdog timer, the emergence of gaps Ping-control and control of the data availability are of great importance. If necessary, it is necessary to ensure the possibility of optimizing the speed of the channel/traffic (variety) control.

Safety

Authentication at the stages of initialization, establishment of data transfer and data transmission, including:

To prevent the possibility of choosing SIM-cards not for recognition (when the modem is connected to a fault, the values ​​of their PIN-codes are entered, which are saved in the modem's memory, they are checked at startup and are not available for reading);

Authentication of access to the APN server;

Control exchange by identifiers when a TCP connection is installed (between two modems or a modem and a server);

Controls the phone number when the CSD channel is installed.

A VPN tunnel between a GSM operator and a dispatch center server.

For certain types, it is necessary to have additional encryption of data, the choice of a lawmaker.

Complex solution for the communication channel

The choice of modems on the distribution network can be adjusted to the software security (telecommunication server), as it is installed on the server at the dispatcher’s office and secure:

Simple connection of a functional software, for example, via TCP / IP;

Safety and stability to the transmission channel (ping, identifiers then);

Routing has been introduced, for example, for additional ports or technological software.

Data flow optimization

Buffered data buffering (8...32 kb) into the modem allows for greater speed of transmission for the optimization of interfacing between RS-232C/RS-485 and TCP/IP sockets, as well as typing modems in systems with a three-wire interface.

Safety support for various modes of work

Fallow in the face of the features of the virishuvannya zavdannya modems are guilty of subtrimming the modes of work, combining two classes.

Моніторинг та керування віддаленими об'єктами з центрального вузла з можливістю оптимізації за різними критеріями, наприклад, максимальна функціональність, мінімальний трафік, відсутність можливості використовувати на стороні сервера Інтернет або необхідність поряд з GPRS/EDGE-каналами використовувати SMS-сервіс.

Another class of rozv'azuvanih zavdan є organization zv'yazku between two points - radio interface (RS-232C or RS-485). In this case, the modems are connected, when the live is turned on, automatically secure a transparent transmission channel between interfaces.

Safety of mindfulness

For the organization of a single GPRS/EDGE-reception with devices that are critical to the opening of packets that are received by them, for example, to override the Modbus or Profibus fieldbus, it is necessary to use time-limited opening of data packets on the side of the receiver. Hoping for the possibility of parrying "rozirvanih" packets for re-experimentation, or work with short packets until the systems appear, which are only practiced on the table of retailers.

Operational benefits

Automated remote configuration of modems in CSD or GPRS/EDGE channels without access to the object, for example: during installation, the factory configuration is changed;

Modernization of the installed modem PZ without intermediary on the object, ideally by GSM-measurement;

Local and remote analysis of parameters in the GSM-merezhі, which allows you to adjust the position of the antenna, analyze the necessary GSM-styles, select the operator of the call, which is the best way to understand the work at the point of installation of the modem, analyze the reasons for the failure of operation;

Automatic control of the balance of the balance of the SIM-card and notification at the time of the decrease in the balance to the specified level;

Creation and security remote access to log-files in the processes of interaction with the GSM-measurement.

Added capacity

Of particular interest is the addition of modem functions and attachments to the appearance (or one part) in one extension for changing the headroom. The reason for this is that modems have hard-wired resources. Apply such attachments:

Modems with a built-in functional software, which ensures the interoperability of the Cosmos with accessories in appearance (for example, autonomous reading of the accumulated results of the simulation);

Modems with decilecom interfaces, which provide multiplexing of data for a large number of interfaces in a single radio channel for independent functioning of a number of systems.

Service PZ

Working with GPRS modems is to be done with a set of technological software, which ensures the security of setting up, testing, remote configuration, monitoring and control of additional interfaces, remote analysis of the parameters of the GSM-merezh, modernization of the installed PZ / IP modem, the OPC-server function.

Visnovki

GPRS-modems, which are victorious in systems in the form of energy resources, may be able to access the modems, and zastosovuyutsya for access to the Internet. Wimogi grow up to them steadily. On this day, the author does not know about the implementation of all the things that could be seen in one modem, which, singsongly, and is not necessary, as to fulfill the criterion of vartost. The article would not be repeated without pointing down the application of the AnCom RM/D GPRS modems in systems in the form of energy resources.

Apply zastosuvannya

ASKUPE (Automated system for the commercial aspect of saving energy resources). Project, implemented by BAT "MOEK" (Moscow Energy Association), 2009

The goal of the project is to ensure the technical and commercial form of thermal energy at the facilities of the Moscow metro, which are serviced by MOEKs, and tse 70% of all living and industrial life of the capital.

Let's take a look at the system for remote access to heat-image fittings, implemented in ASKUP. The company "KOMCOR" (trademark "AKADO-Telecom") will be a corporate multi-service measure for BAT "MOEK", within the framework of which it will provide access to heat-imaging devices using digital channels AKADO, de stink, and GPRS-channels of the GSM operator MTS. Head of care information security transmission of data is denied for help special services MTS for corporate clients(Visions APN, local static IP addresses). System integrators (NVO "Teplovizor" and TOV "Evrocom") install AnCom RM/D modems in ASCUP (more than 800 data points).

During the installation of modems, the main problems were related to the choice of the place to install the GSM-antenna in the basements. The following technique was viroble:

All operations considered below are carried out with the SIM-card of the GSM-operator selected from the system;

Search for zones of visibility of the signal (want to use the minimum level) - for the help of a stylish telephone, often by ordering from windows, airways and specific areas of the walls;

Zone control for an auxiliary AnCom RM/D modem and NetMonitor GSM_RM software. The signal is measured according to the number of visible GSM cells. It is necessary to ensure:

Larger value for minus 95 (RxLev: -65…-95);

The MNC of visible phones can be overridden by the MNC of the SIM card operator (if the SIM card operator's cells are unavailable for access to emergency services you can see information about the available styles of other operators);

Visibility is more than 3 hundred, one of the few GSM-1800s has more free slots (BCCHfreq: GSM-900 from 1 to 124 and GSM-1800 from 512 to 885);

The presence of a high level of signal, but 1...2 stylists GSM-900 can not secure a stable GPRS connection through this high level of engagement (IP-addresses are not expected);

Control of the GPRS work (given IP address from the side of the network) for an auxiliary modem (the mode for viewing technological information is enabled) and software GTem (the presence of a GSM connection is not guaranteed by the GPRS robot);

Control of the work of the system (staff adjustment).

It is wrong to turn on the antenna with an already long drome (extinguishing on the 5 m RG58 drome at a frequency of 1800 becomes 4.5 dB);

The most correct way is to move the modem to the zone of the embedded reception, vikoristovuyuchi sv'yazok between the modem and the attachment to the thermal image of the RS-485 interface;

As a last resort, the choice of modems, which are used in fittings with a thermal image, is often difficult;

Time-out to ensure the stability of the connection must be selected during the period of testing by adjusting the heat (including in the test mode) and during the period of shaving the socket, which is not vicorated, from the GSM operator;

Tighten the antenna with low extinction at the cable with a high gain factor (for example, Ant K996A 900/1800 MHz: gain, dBi - 5/4; extinction at the cable 5 m, dB - 1.8 / 2.5).

The system of telemetry in the form of gas "MOSCAD" was implemented by TOV "Indasoft", 2007-2009.

The system of a commercial type, which ensures control over the modes of gas compression, monitoring will become a node of the form of that security alarm. The installation and commissioning of the first and other lands were carried out: 1464 objects in 15 regions of the Russian Federation. Removed the suspension of GPRS communication in different regions.

Polenly realized Polyagayat in the Ideologi “Active Control point”: the controller of the controller of the technologic parameter is the Paima -Rishoda Nannya Dannya on the upper rangov, and not the Cheka of the Circassians in the cycle in the cycle in the cycle in the cycle in the cyclist

Using the specialized MDLC protocol of the Motorola company guarantees the delivery of data to the control room of the regional gas company, remotely configuring and programming all controllers in the system. Through the Internet gateway of the regional gas company that server, the data link is connected to the controller of the upper level ACE 3600. The controller "sorts" the MDLC package, retrieves the data from the gas station, processes it, places it at the internal database and initia the server, transmits which is responsible for data dispatching systems of the regional gas company.

Protection of information in the event of unauthorized access is secured on a par with the MDLC protocol. Reliability parameters are taken care of for the operator's reservation system for GSM communication (two SIM-cards).

The AnCom RM/D wireless GPRS modem is an important element of any kind of modern power-generating system. Safely in the system overhead links, GPRS modems allow you to combine hundreds and thousands of remote devices into one. informational measure. The use of AnCom RM/D GPRS modems in automated systems makes it possible in real time to receive accurate, reliable information about energy savings, human factor, to avoid emergency situations, to take care of the technical camp, having adjusted that application, and, as a result, to increase the economic effect in the form of zastosuvannya priladіv form.

I.V. Dianov, technical director,

TOV "Analytik-TS", Moscow,

Organize access to the Internet on a PDA or on a laptop today, do not become special problems. In principle, a laptop is the ultimate computer, which, as a rule, can have all standard interfaces (Ethernet, USB) or the ultimate analog modem for access, which communicates, over a dial-up telephone line. With a small computer (which, obviously, is not a communicator) will be more foldable - for connecting with a modem via USB, the mother is to blame the most dartless interface).

It is clear that both a PDA and a laptop are mobile attachments, so it would be foolish to obfuscate them with wires for accessing the Internet. Let's talk about wireless methods and access to the Internet from these mobile devices.

Іsnuє kіlka ways to organize mobile wireless access to the Internet. Of these, the most popular and universal at the moment in Russia style call for the help of a superb GSM-phone, which allows you to organize quick access to the Internet using GPRS technology (for to this particular type gateway to Merezh stylish phone). However, this time sometimes has problems with sleeping victories a laptop and a phone, for which it is necessary to set up a remote connection (USB or RS-232), dartless call(Bluetooth, InfraRed, Wi-Fi), so you don’t have to go (even if you still need to call on the phone).

GSM/GPRS modem with USB interface

Finding that universal solution for equipping a PDA or laptop with a mobile Internet, GSM / GPRS modem with a USB interface. There were few such outbuildings for sale today.

Some of them are just GPRS/GPS-modems - without the ability to change the mode of communication, otherwise they allow you to connect a hands-free headset, for help, you can talk on the phone from your computer.

However, regardless of their compactness, such models are not as handy when stuck, so they “hang” on a PDA or a laptop for the help of an additional cord, take advantage of the savings, ruin and intersect mobility (for example, for a USB device, a PDA often needs advanced interface - cradle).

GSM/GPRS PCMCIA cards

Since you don’t have the ability to connect to the Internet to connect to the phone of that laptop, then you can bring a special PCMCIA card, which allows you to organize high-speed access to the Global Network and turn your laptop into a fully functional mobile phone with the ability to talk in this way overpower the fax. and SMS/MMS alerts. Before we speak, please let us know that for connecting to the Internet, a GSM operator and a valid tariff plan must support GPRS.

Cards with PCMCIA interface (PC-card Type II) are not so popular these days. Acts of them, as described above, are simply GPRS / GPS-modems without the ability to change the mode of the move, but we can’t get away from us. And even on the speed of GPRS-zadnannya zastosuvannya such zabiv, like Skype, or others that allow you to say, you may have to click on jams in the transfer of movies, that chimaliy voice traffic will have to pay for GPRS prices, which, sing-song, be more expensive, lower sound to a mobile phone that is located in another place in the country.

So, in our opinion, modems are more convenient, like making roses for connecting a headset, which allows you to talk on the phone from a computer, and clumsy software for emulation of all phone functions - for example, like OvisLink WGP-1500, Billionton PCMCIA GPRS/GSM Wareless modem or Neodrive GPRS-100S (the kit comes with a passive headset on a special clip - a headset and a sensitive microphone).

Other features of such modems include the presence of two or three GSM-bands (GSM 900, 1800, 1900), handy expansion of the SIM-card card and the original design of the antenna (it will be known). For example, in the Billionton modem, the design of the antenna allows you to either use it in the middle, I will attach it as compactly as possible, or hang, positioning for short capacity I will accept. And the Neodrive GPRS-100S modem can be called a rotary antenna, but, although its design looks better, lower than the Billionton modem, its attachment is less compact.

To access the Internet, it is sufficient to install the drivers for a valid PCMCIA card and install Merezheve connection However, if you want to speed up all phone functions, you need to install special software. The virtual keyboard and functions of the software, as a rule, are implemented in the primary "telephone" design and are safe simple function I'll call you on a call. Obviously, navigate through the menu of such a phone great screen the laptop is richly simpler, you can look at the icons on the small screen of a style phone. In addition, such software can provide panels with additional functions. With the program, you can install GPRS-record, send SMS, e-mail and fax, as well as check the notepad, synchronize data with the organizer and check all the operations that are on the phone.

To use such a card as a typical mobile phone, it is necessary, especially, to connect the headset, which is included in the kit (type of microphone and speakers of a laptop and attachments are not used). If you can call someone, what you can find, or call someone, like from the headset of a ringing phone. The only thing that PCMCIA-cards can see in a phone with a headset is that the system will be able to spend more than an hour working with a laptop, so that the laptop is disabled, then it’s impossible to speed up with such a phone.

GSM/GPRS CompactFlash cards

However, the PCMCIA-interface is only available on laptops, so the PDA will not be able to connect to the Internet for the help of built-in attachments. And yet there are more universal solutions based on CompactFlash (CF) or Secure Digital (SD) interfaces, which can work with both laptops and PDAs.

For example, the Neodrive company has a GPRS-110S model, which is identical in its characteristics to the GPRS-100S model for PCMCIA, but also has a CF interface, which allows you to connect it to an intestinal computer with such an interface and convert it to a communicator.

GSM / GPRS CF-, SD-cards, as a rule, are foldable, and also, expensive, lower GPRS-modems based on PCMCIA. This is due to the need for a supplemental battery, which is located on the extension. And before this battery, you will need an additional indication of it, the possibility of supplying good life and the plug for charging. To charge the battery in the Neodrive GPRS-110S, there is a special USB-adapter, which is connected to the power socket, which is installed on the front side of the attachment, next to the antenna.

The kit with Neodrive GPRS-110S on a special clip comes with a headset - a headset and a sensitive microphone.

Attachments based on CompactFlash and Security Digital are universal - in order to win them over from a laptop, a special adapter for PCMCIA is needed (Neodrive GPRS-110S CF/PCMCIA adapter is included in the delivery set). To install the GPRS-110S model in combination with a PDA, the delivery package also includes the Pocket PhoneTools program, because due to its functional capabilities and interface it is similar to the PhoneTools version for a laptop, so it converts the PDA to a standard style phone (more precisely, to a communicator).

It's a pity, it's impossible to connect such GPRS modems like a phone wireless headset Bluetooth, navit as such a PDA interface. On the right, in that the GSM-telephony of such modems works only with their own high-power headsets and does not beat the capabilities of a computer.

Significantly at the end, the price of such outbuildings, which are promoted on the Russian market, varies from 100 to 300 dollars.

Information transfer by means GPRS allows you to easily create systems for remote dispatching and control of devices, as well as stationary and objects that are shifted. Stopping GPRS data transmission by a modem can replace a widely used GSM network CSD (two-site modem) with a GPRS network. The price for reasonable tariffs for all operators is economically viable.

The company ІnSAT promotes a wide choice GPRS modems. The most popular for industrial zastosuvannya GPRS modems selections of companies MOXA, ICP DAS, Segnetics, iRZ, ARIES, TELEOFFICE.

Leica receivers for HIS are widely recognized by technical service specialists, emergency response teams, floor inspectors and utility services.

The standard Leica modem is a compact accessory that looks like a field controller. The front panel of the prior takes a bright and clear touch screen, which ensures the security of both manual entry and editing of data, and control of the capture process. Pushing processor i significant obsyagi operational memory I allow you to do without any hospitable borders pratsyuvati with great obligations of tribute. Most modern GIS receivers are equipped with digital cameras, built-in speakers and a microphone, expansion slots for memory cards and USB sockets.

Wireless Bluetooth and Wi-fi technologies, which are equipped with modern Leica GPS receivers, increase the possibility of receiving and transmitting data, allowing you to connect to mobile phones or tablet computers for receiving corrections to the real time mode with a real or virtual VRS base station, for capturing maps via the Internet. Also, you can easily get in touch with various devices, for example, laser rangefinders, barcode scanners, or digital cameras for taking additional capabilities in the minds of the sexes.

Irrespective of those that Leica receivers for GIS are recognized for autonomous work with submeter accuracy, you can still turn it into a high-precision geodesic receiver and take coordinates with accuracy to a few decimal meters. All you will need to do is to turn on the sensible call antenna and turn on your GIS-receiver as a great field-receiver rover for post-harvest or in real-time mode. The Leica GIS receivers can be equipped as standard with a receiving radio or a GSM modem.

The American company Enfora is well known in the whole world, including in Russia, as one of the leading manufacturers of modules and modems for GPS-systems for keeping track of objects (Fleet Management). These extensions are widely occupied by automobile, transshipment and maritime transport companies, insurance companies, as well as shops selling cars, motorcycles, boats and yachts. The Enfora line of products has personal GPS trackers, which are designed to control people's mien and allow sending an alarm signal with exact coordinates to the phone numbers in front of the SMS alert.

The principle of operation of GPS systems

Today, GPS/GSM-monitoring systems (GPS/GSM Fleet Management, abbreviated as GPS FM) offer a great range of services for professional transport, trade and insurance companies, as well as for the private sector. Vikoristannya modern methods control and management allow optimizing the transportation system, significantly speeding up the cost of PMM and transport repairs, as well as preventing car thefts and hoarding of cars and vantages.

Following the data of one of the leading American statistical firms Aberdeen Group, more than a million GPS FM devices are in operation in the USA. The average GPS/GSM-monitoring system in the country showed the following results:

• improved transportation efficiency by 12.2%;
• zbіlshennya kofikіtsієnja vykoristannya transport zabіv – 13.0%;
• arrears in the hour of delivery of vantazhіv by 14.8%;
• decrease in pardons of operators by 27.9%;
• a decrease in the number of sludkiv in the form of samples stolen and hoarded by transport and vantage by 32.1%;
• the cost savings for the repair of a single vehicle is $1100/car;
• savings to the fund of wages for the reduced transportation time - $ 1625 / person;
• good savings to the payroll fund (for the cost of implementing an automated control system and a short number of dispatchers) - $ 1,300 / person;
• cost savings on PMM for route optimization cost - $1700/vehicle.

The principle of operation of GPS FM systems is small. one.

Systems for GPS-monitoring of moving objects, in fact, are folding transport automated control systems for tracking satellites, ground base stations, mobile extensions (GPS-tracker), a software security complex, a central control room. GPS-satellites, located on 6 orbital planes with orbits of 20200 km and 55 °, are constantly wrapping around the Earth. On board the skin satellite, there are transmissions, continuously transmitting signals at two frequencies: 1575.42 and 1227.60 MHz. Installations on the controlled object GPS/GSM-mobile terminal selects the maximum possible amount of data from satellites and sends them via GPRS to the central server.

Similar central servers can be supported both on local corporate levels and on a regional and global scale. The server has its own office to process data from satellites and create a file of in-line surveys of reporting geodetic information. In order to access the central server, there is information from the used controlled objects, the number of which is only between the intensity of the server itself and the application software. The operator on the central server can provide accurate navigational information about all objects, and estimate in real time the hour from the start to the finish of the route. In addition, the database contains archival data about leather objects, vantage, transport costs and water. Owned by Enfora and modern software GPS/GSM-monitoring systems are allowed to receive the following information at the central control point:

• exact geophysical coordinates of the object, which are updated by skin seconds;
• camp of the controlled object on the maps of the month in real time;
• shvidkist ruhu;
• general technical information about the car, water, vantage;
• history of switching on and off;
• streaming information about tire pressure;
• the history of the entire hour of disruption (refueling and zliv);
• assignments by the dispatcher route and real trajectory;
• completed at a specific moment in the hour;
• ochіkuvany hour pributtya at the job item;
• an hour of uninterrupted work dvigun;
• temperature in the middle of the car and overboard;
• cars that do not qualify for the dispatcher's request;
• Medical parameters of water (pulse, tick, temperature).

At different times, the assigned functions of the software security can be supplemented with the improvement of the individual features of the locker. So, for example, insurance companies can enter information about the insurer, yoga vantage and transport costs into the database. Firms that trade in transportation costs can control the timeliness of customer payments. Firms that rent cars can check their customers at any point in the world.

In addition, the operator can plan individual routes and manage them using GSM / GPRS-merezhey. It is also hoped that it will be possible to change and optimize the route by improving the road situation, repairing roads, meteorological minds. The operator can tell you about the need for a planned drill for repair or repair, as well as the coordinates of the most friendly place for him. In times of non-delivery conditions, you can quickly replace the transport cost and reduce the delivery vantage. As one of the options for the security system, it is possible to fix for a few seconds at the central dispatcher's station, whether it is in the given route and on the phone, PDA or navigator, water alert.

In the United States, for support, in a number of ways, a program is being developed to create a global network, using the order 911 service. at the nearest point of the ordering service and at the central dispatcher's office. Come on in and make up for the cost savings and the increase in profits from business. In addition, the stench allows you to secure and increase the efficiency of the work of water, as well as increase the control of yoga robots.

Є function of storing GPS-alert in the independent memory of the module. For Enfora GPS-navigators, a technique has been developed that allows displaying GPS-information on various interactive maps. This allows you not only to take coordinates on the central server, but also to monitor the position of the object on the map in real time. The GSM2338 model supports PPP, UDP API, TCP API, UDP PAD, TCP PAD, AT commands via GPRS channel and via SMS. This allows you to fully highlight the unique advantages of Enfora products, for example - PAD and Event Tools.

Among other appendages functionality you can mean like this:

To live the GSM2338 modem, it is possible to expand the voltage range - 7-40 V. Li-ion battery. Starry look GSM2338 is shown in fig. 2.

On the front panel, there is a SIM-card switch with automatic locking and three light indicators of work modes. On the back panel there are antenna sockets FACRA, socket Molex 43024-0800 for inputs / outputs and sockets for connecting a voice headset (2.5 mm Headset). On the Molex sockets, there are contacts for connecting the life: the type of the ignition key and the type of the battery. In addition, on this rose there are two input/output programs: one common recognition and a 2-wire serial interface (Tx, Rx). Koristuvalnytsky input/visnovka allow to connect to the modem of different outbuildings and configure them for the help of the Event Engine. GPIO1 Entry/Display Programming (Pin 7 of Molex 43024-0800 socket) can be set to High or Low to the commands: AT$IOPULUP = 1 or AT$IOPULUP = 0.

Similarly, for the help of AT commands, GPIO2 input / output is programmed (pin 8 of the socket). You can connect to a special GPIO3 connector (pin 6) zovnishnі lansyugs. The maximum strum on which tie is not responsible for exceeding 250 mA. When the modem is reset, the station of the output is changed, minus is applied to GPIO4 (pin 4). The modem is programmed for the help of the Event engine in such a way that for the current life of the robot, I will attach it to the internal battery. If necessary, notification about the channel can be sent in the form of SMS or UDP notification. On GPIO5, a constant life is supplied without interruption to the battery. When live is enabled on this drive, the modem is restarted. This will erase all GPS data. GPIO6 and GPIO7 input/output (pins 2, 3) are designed for 3-wire serial interface (Tx, Rx, GND). Also, the stench can be adjusted to control the GPS and GSM / GPRS connection. GPIO8 (pin 1) is fed from the ignition key. This visnovok can also be used as a jumper when programming for help with Event tools. The modem can be programmed in such a way that the NMEA alarms were overpowered in the upcoming fluctuations:

• passing tasks hour;
• perepische tasks kіlometrazh ruhu;
• the transfer of the specified speed was indicated;
• fixed rebuying at the zone from the given coordinates;
• vіdbulasya zmіna I will become vvodіv / vіvodіv;
• vydbulosya inclusion/vimknennya inflamed;
• became the appearance / sign of companions.

For better access, you can use the Enfora test server, which is constantly open for free access. With this help, you can control SMS, NMEA-alarm with the GSM2338 modem, as well as change its configuration. The model is available in two modifications: GSM2338-00 with backup battery and GSM2338-01 without battery.

Spider MT-Gi GSM2354, Spider MT-Gi GSM2356 are compatible with other GSM2338 models, which may include GSM and GPS antennas. In addition, these two models have an open voice channel. The GSM2354 model is recognized for operation in the American frequency band 850/1900 MHz, the GSM2356 model for the European frequency band 900/1800 MHz. These models are also available for options with and without a battery.

Enfora Mini-MT GSM2228 is a portable, miniature GPS/GSM/GPRS tracker, recognized first for everything for monitoring people's well-being. This model can be more narrow like a mobile “alarm” button for summer people and children. In addition, this model can also be used as an external transport tracker. The old look of GSM2228 is shown in fig. 3. The modem is made in a hermetically sealed plastic case, which is expanded: 100×59×25 mm.

The modem can be universally recognized and can be manually automatic mode select current coordinates and transmit information by GSM-channel to the given telephone number or central server. In the model, the emergency transfer mode was transferred to the task number when pressing one key. Access to GPS data is possible in NMEA and SUPL formats. The modem can be autonomously powered by a built-in battery. The basic configuration comes with a 1340 mA/year Li-ion battery. Charging of the battery is carried out via USB socket in the car twill adapter. The modem is requested for help with some functional buttons.

The Push To Call button allows you to call the next programming number. The Mini-MT modem can send an emergency SMS to 5 different addresses.

The Set Geo-Fence button is assigned to search for a given radius. Cordoni can be asked to change the corysteve and save the memory of the module. In vipadku, if you can not see the desired satellite, GSM2228 will vibrate beep pardons, which are ahead of the coristuvacha about the need to come out of the blocking ukrittya (metal dakh, wet leafing of trees, tovstі concrete walls thinly).

The User-Defined button is assigned to select the desired function of the GSM2228. For example, you can choose the following functions: call the number, using the programmed number, on the emergency call button; conduct a survey at the radius, at the sight of the factory setting; send an SMS with current coordinates to a GSM number or a central server, etc.

Modes of robots and control over help chotirioh light-one indicators. Through the USB port, you can display GPS NMEA data on a PC for work with maps and program the GSM2228. The Headphone Jack rose is used for connecting a voice headset in quiet situations, if a loud call is not needed. System voice call allows you to rozmovlyat iz zdalegіd zazdalegіd zaprogramovanim subscriber as a sizable stylish phone.

In the normal working mode of GSM2228, through the task of an hour interval, the coordinates of the clock in the NMEA standard are sent to the central server. To activate this mode, it is enough to prescribe a few commands that specify the addresses of the modem and the server, as well as specify the transmission modes. So just like in the beginning of the GSM2338 modem, the GSM2228 modem can be programmed in such a way that you can override SMS or UDP-alert at the current time (setting hour, time, speed, zone with specified coordinates).

Enfora Spider AT GSM5108 is a self-contained GPS/GSM/GPRS tracker, designed specifically to control the movement of various objects, placed on a time or storage basis (roof containers, conserved possession, reserve tanks with fire or drinking water). ). The main feature of Spider AT is the most significant analogues - a record low energy saving in autonomous robots. This model can be used without recharging the battery for up to three years!

The Spider AT modem is made on the basis of the Enabler III Low Power Platform (LPP) micro-power GSM/GPRS module, which is the combination of a GSM/GPRS- and GPS-module with a built-in microcontroller. It is especially important that the module LPP0108 is assigned to work in the learning mode. Vіn nadsilâє іnformatsiyu pro tochі koordіnіtsіyu іn razі і razі аn emergency sprаtsovuvannya аbо behind direct request іz central server. In its own right, the main feature of the LPP0108 is in other cases of GSM / GPS modules (GPS0401–GSM0308, MLG0208), which are used for uninterrupted monitoring of traffic and constantly transmit geophysical information dozens of times to the internet. Therefore, the Enabler Low-Power Platform (LPP) module, LPP0108, cannot be used as a transport tracker.

In order to bring the power supply to a minimum, all the control of the Spider AT modem is put on the central server, the distribution is done at the control room. When you configure the parameters, that control of Spider AT works remotely through the Enfora Services Gateway. For this reason, the Provisioner software, recognized specifically for Spider AT, is awarded. The Spider AT GSM5108 modem is prepared in a vandal-resistant case, but it can be installed in a GSM and GPS antenna (Fig. 4).

Spider AT modem

• basic module LPP0108;
• vbudovaniya microcontroller MSP430 Texas Instruments, scho vikoristovuetsya for keruvannya and data processing.
• rechargeable battery BAT-0007-0001, 4200 mAh;
• utrimuvach SIM-cards;
• pilovologozakhistny case with impact-resistant polystyrene;
• built-in GSM-i GPS-antennas.

Dimensions dimensions - 147 × 63 × 20 mm. Vaga - 168 g. The GSM5108 modem operates in fully automatic mode and does not require additional maintenance. The fallow type of modification Spider AT is equipped with either a vibration sensor (LPP0108) or an accelerometer (LPP0118-40). LPP0108 vikoristovuetsya for fixing the smallest move. In this case, the signals are analyzed by the microcontroller and matched with the GPS signals. Such a pidhіd allows you to miss the pardon warning of an alarming signal, which confirms the beginning of the movement. The microcontroller processes data, forms a GPS NMEA alert and sends it via the GSM/GPRS unit to the central server. On the other side, from the central server, you can send commands to the module to control, and change the modes of yoga robot, using an additional UDP API channel.

The base module for the Spider AT modem can have two inputs and two outputs. The input/output modes can be programmed for additional Event Processing to enable reed sensors in the opening, hand sensors, audio sensors, temperature control sensors, etc. SMS server or UDP notification via GSM/GPRS network. Robot control and configuration of Spider AT parameters is remotely controlled via the Enfora Services Gateway (ESG) auxiliary service management server. At the same time, standard Internet protocols are used, which allow one server to control more than 100 thousand. modems Spider AT. ESG service is up and running again support and GPS update. This program is easy to integrate into the existing IP-merge. In principle, ESG hopes to be able to work, be it in distant annexes that supports IP protocols. The ESG switch allows you to significantly speed up pennies and an hour during the development and operation of systems for controlling the transfer of remote objects.

For direct control of the modem, the Provisioner Software (PS) application software, developed specifically for Spider AT, is used. Note that Spider AT GSM5108 can be beaten more than once from PS. The PS application suite allows remote control of the GSM5108, via a GSM/GPRS channel, with different support servers and the Enfora Services Gateway.

The Provisioner software package supports the main software industries - such as, for example, MS SQL Server MySQL, Oracle. Therefore, in times of need for the introduction of additional modes of operation, it is possible to create an individual version of the koristuvach, which will become the specifics of the control specific outbuildings. The concept of programming and control of the Spider AT modem is based on the common task of different logical groups. Such a pidhіd allows you to sort out the songs according to the theme and quickly know the adequate reactions to them.

Like a butt, you can set up a system of movement of containers at the great terminal. Leather container, which is transferred to the warehouse, takes away its own Spider AT. Information about vantage, think of the terms of this saving to be entered into the data base. Vіdpovіdno to tsih dannyh vznachayutsya scenarios for control and dіy vіdpovіd. For example, it is necessary to save the container for the right temperature and correct it in the warehouse at the right time. Depending on the display of the Spider AT modems from other containers, the dispatcher selects the optimal group of containers and the optimal place for placing this container in the same group. As a standalone subdivision, you can plan, for example, like this:

• removal of the container from the warehouse earlier for the purpose of the term;
• unauthorized movement of the container to the outside zone;
• falling container from the top row;
• unauthorized container rosette;
• moving temperature and saving too much.

Dії y vіdpovіd zdіysnyuyutsya vіdpovіdno to konkretnye scenarios. In case of an emergency, Spider AT transmits alarm notifications, as if through the Gateway service to get to the support server.

Information that needed to be processed for the help of the Provisioner is compared with the information from koristuvacha appendage that database. As a result, the koristuvachev proponuetsya negaino vikonati sevni dії u vіdpovіd. In addition, emergency signals can also go in parallel to various security, police and emergency services.

The Provisioner program allows several options for configuring the parameters of the modem, which are recognized for different modes of operation of the GSM5108. For example, in a static mode, the modem sends notifications about your camp ahead of schedule. In dynamic mode, the modem will notify you about the beginning and end of the move after a specified interval. This regime is most often victorious in vipadkas, if it is necessary to securely fix the fact of the transfer of a controlled object (ATMs, vending machines, office equipment). In the modes of cordon damage, there are various combinations of movement between the given zones and such guards, like, for example, the exit between the zones, the consumption to the outside zone, the speed of movement between the zones.

Provisioner software is supplied for an additional fee as licensed disks, licensed for a different number of controlled objects. For example, Provisioner License EWS0201 for one attachment. Optionally, you can request Enfora Provisioner Support (catalog number EWP0201).

GPS navigation systems and vehicle monitoring based on Garmin navigators and Enfora modems

The light leader in the selection of GPS-navigators by Garmin and Enfora was laid in 2008. for the sake of supporting the Garmin Fleet Management Interface (GFMI) v2 with Spider Gu GSM2338 modems. Combination of Garmin GPS-navigator and Enfora GSM2338 GPS/GSM-tracker in one device made it possible to create a closed loop system "GPS-satellite - transport zasib - central control room - ordering service". The GFMI system allows companies involved in fleet management to provide interactive services to both fleet managers and private companies. With the help of GFMI, dispatchers can check the traffic at real time and adjust the yoga robot mode. From the other side, the water can contact the dispatcher and ask him for the necessary information.

A diagram illustrating the principle of GFMI is shown in fig. 5.

For sleepy robots, special software is required with a GFMI support - like a Garmin navigator, or an Enfora modem. Software versions of Enfora PKG47 and Garmin 6.10 support GFMI. To activate the FMI GSM2338 function, you need to obtain an additional access code for the skin modem from Enfora. Please pay attention to the fact that not all GPS-navigators can work simultaneously with the Enfora GSM2338 modem. The list of navigators with the FMI Enfora-Garmin support is shown in Table 2.

When working in a pair, the RS232 port of the Enfora GSM2338 modem is connected to USB port Garmin navigator for the help of a special cable Garmin FMI cable 010, which can change the interface and life 5 V. The management of GFMI functions is carried out with the help of special AT commands, developed by Enfora. The commands are sent from the central server to the TCP API protocol via the GSM/GPRS channel to the GSM2338 modem. After receiving this command, the modem vibrates an FMI message and transmits it via the RS232 port to the Garmin navigator. Navigator processes and displays the result on the display screen. The GSM2338 modem is transmitted hourly via the USB port of the navigator, which sends it over the GSM/GPRS channel to the central server. In the simplest version of the Garmin-Enfora FMI betting robot, you can try it with the help of the Enfora support server. In order to enter the whole site, it is enough to prescribe the APN, UDPIP, Friends, Port parameters in the GSM2338 modem. From this site it is possible to send commands to the GSM2338 modem (Fig. 6).

So, for example, the command AT$GFMI = 1 is broadcast via the GSM2338 modem to the Garmin Nuvi 205 navigator and activates the GFMI function. If so, a new window appears in the main menu of the navigator with the inscription Dispatcher. The main GFMI menu of the Garmin Nuvi 205 navigator contains several main divisions (small 7):

• teeth;
• reminder;
• know the place;
• about water.

Navigator Nuvi 205 May Touch screen (choose the appropriate menu item with a simple dot until the image appears). The water dispatcher can exchange sufficient notifications. For which you need to select the menu item "Information, holidays" and type on the keyboard, which appeared, the required text (small 8).

Having received the command AT$GFMI=6,0002, "59.50827", "30.22929", "TESS NORTH WEST" from the server, enter the coordinates (latitude and longitude) on the navigator screen, as well as the name ("TES Pivnichno-Zakhid") Chergovy planned teeth. Planned points are set in advance by the dispatcher and are saved in the navigator in the “My teeth” section. The water can collapse with a navigator along the route from grain to grain. Skin passage or failure to pass a given point is controlled by the dispatcher.

The ideology of GFMI support is based on the built-in software security modules Enfora Event Engine. All notifications that are vibrated by the GSM2338 modem and are sent by it to the central server, are sent by the pods of this software. For example, as if having read the information on the navigator about the need for teeth, after reading it or having seen it, the following commands will be sent to the server: AT $EVENT=89,1,89,100,104; AT$EVENT=89,3,40,89,1075864263 // SEND UDP Message to the Server. At this time, the GFMI control list has thirty-one AT$GFMI commands and thirty-two AT$EVENT commands. The stench is reportedly described in the document.

Currently version 6.0 (FMI V1, FMI V2) of Garmin software supports the following services:

• • textual references in full form (128 characters);
  • teeth;
  • hour of arrival at the tasks item;
  • automatic notification about the arrival of the tasks item (or delay);
  • update (change) of data about the route from the control point;
  • notification delivery confirmation (FMI V2);
  • standard water levels up to 200 resp. (FMI V2);
  • personal water data (FMI V2);
  • technical state of the car;
  • shokhviliny podomlennya about camp transport (FMI V2);
  • ping to the GSM2338 modem (FMI V2);
  • additional data to be filled in by the client.

Garmin Fleet Management Interface protocols are approved. This is a detailed description of the instructions for distributing the various application software Garmin Fleet Management Interface Control, Specification. In addition, Garmin proposes a ready solution for looking at application software for the central GFMI server. An example of the interface of such a program is shown in fig. nine.

Interface for adaptation programs for the primary dispatcher, which does not have any special skills to work with GPS-navigation systems. Placed at the main menu function keys, which can be assigned to more GFMI protocols. With one push of a button, the dispatcher can select the appropriate service and set the required parameters (small 10). The main parameters of the object that are being controlled are constantly displayed on the screen: current hour, number of registered satellites, coordinates, speed

Introduction to post systems bilateral communication between the dispatching point and the water allowed to significantly improve the system of security of transport services. For some reason, if for some reason GPS-data from a particular car disappear on the dispatcher screen, it is not possible to find a text request on your navigator. If there is no warning, the dispatcher can remotely block the fire, and send the door to alert the guard to the service. In addition, in the GSM2338 modem, the “panic button” function has been transferred. Therefore, in critical situations, you can send an emergency to the dispatcher yourself.

The Garmin Fleet Management Interface GPS system is widely recognized throughout the world. There are close to seventy great partner companies listed on the site, such as Trimble Mobile Resource Management, SkyPatrol, Datalink Systems, GPS-Buddy, Beacon Wireless, etc. Therefore, both transport companies and private individuals can choose a GPS-tracking system, according to their individual needs.

Garpy

As an example of using Enfora modems in Russian GPS-monitoring, you can use the Garpy system, developed by Olikom SPb. This Russian company sells Enfora products for VAD (value added dealer). As an additional service, the services are provided with technical consultations, support and support, complete set with accessories, installation and maintenance, warranty service. For the help of the Garpy GPS-monitoring system, you can independently, at any hour, from any point of the world, control on the computer screen or PDA, more precisely, the location of your transport security (TS).

For a review of information about the object, it is necessary to have a PC or a PDA with the ability to access the Internet. There is no need for any specialized software for robots with a GPS-monitoring system, a subscription fee is not charged. However, there is a trace of the fact that only those clients can use the Garpy system, as they have acquired GPS / GSM-navigation without intermediary from the Olikom SPb company. Access to the website of the monitoring system is subject to the assistance of an individual login and password. Therefore, it is impossible for third parties to take away information about the controlled object of another client. The head interface of the Garpy system is shown in fig. eleven.

The Garpy grid system can be used both with standard raster maps, and with maps from OS Maps, Google, Yandex, "Hybrid Maps" and others. (Fig. 12). Switching between the modes of work is carried out behind the help of virtual keys, like rotting in the right corner of the screen (Fig. 11).
The left side of the Garpy interface has a split menu. Koristuvach may be able to post the following information in real time:

• unique login TK;
• hour of the rest of the day TK;
• the address of the place of the rest of the TK;
• camp of TK at a given moment to the hour on the map of the month;
• current balance of the account for the SIM-card, which is fixed in the GPS-GSM-modem.

When pressing on the "Trajectory" key, a graphical image of the trajectory of the TK for the remaining two finishes will appear on the map. Also on the map will be marked points and trivality of teeth (Fig. 12).

When you click on the button "Setting" a menu will appear with the next items:

• Attached.
• Zoni.
• Podії
• Call.
• Profile.

Distribution "Pristroy" has data on transport zasib, GPS/GSM-enabled connections, control of peripheral attachments of the car (flying, doors, fire control sensor, temperature sensor, pressure sensor in tires etc.). At the "Zone" branch, you can designate different zones on the map. When you press on the zone with the chosen name, for example, "Center of St. Petersburg", it immediately appears on the monitor screen. At the distribution “Podії” for the bugs of the coristuvach, there are singing incidents that happened with a particular vehicle. At the Zviti branch, the archives of the parking lots of the TK are collected from the assigned dates, the accuracy and the address. Koristuvach can independently see old archives of sites. In the "View" mode, the format of views on the head side the data menu for a specific vehicle. At the “Profile” branch, special contact details of the client are saved.

In order to connect to the Garpy GPS-monitoring system, you need to fill in the technical specification form, in which the type and brand of TK are indicated (the number of TK per one koristuvach is not bordered), the type and brand of GPS / GSM-enabled, which is connected to the peripheral car possession. For corporate replacements, it is possible to develop, prepare and connect additional control modules for individual technical specifications. In addition, it is possible to place the server of the monitoring system to the Garpy type without intermediary on the deputy's Maidan. Detailed information about the work of the Garpy system can be found on the websites. To get to know the demo version of the system, you need to go to the site and type in the same code word "demo" as your login and password.
