Description

 The invention relates to communication systems, in particular to a multifunctional system for dispatching and monitoring mobile and / or stationary objects, and can be used in protection and search systems for cars, in corporate control systems, informatization and protection of large companies, shopping complexes, banks, monitoring unauthorized entry into residential and non-residential premises, etc.

 There are many different systems for locating moving objects, the most interesting of which are the American global positioning system (GPS) Navstar, as well as its Russian counterpart, the Glonas system. These systems are a grouping of satellites placed in low Earth orbit, each of which determines with high accuracy its location in space by stars and every second in the high-precision system of a single time satellite for all satellites broadcasts its coordinates. A receiver located on Earth receives information from satellites and measures the delay in signal arrival. The receiver computer solves the problem of determining the location of the receiver itself in space.

 A known GSM type radio telecommunication system adapted for mobile subscribers in which the level of service can be increased or decreased using one or more additional service functions and in which, in addition to the indicated mobile subscribers, includes one or more base station systems, further providing control radio resources necessary for establishing and breaking connections with mobile subscribers located in the area covered by the corresponding base station systems one, or one or more local service function switching centers for mobile subscribers connected to one or more higher-level devices, said higher-level device or devices including or including software related to basic functions and valid and corresponding additional service functions (RF patent N 2147796, CL H 04 Q 7/22 from 04/18/95).

 However, the known device is intended only to optimize operation in a GSM cellular network, which limits its functionality.

 In technical essence, the closest to the proposed invention is a telematics system, which is a satellite system containing emergency beacons, a second on-board receiver, a first on-board storage device and an on-board transmitter, the second input of which is connected to the output of the first on-board receiver, and the third input - with the output of the second on-board receiving device, the receiving device in series, the first information processing device , a device for interfacing with communication networks, the second input of which is connected to the output of the receiving device through a second information processing device, a monitoring and control device and a communication device for search and rescue organizations (RF patent N 2027195, class G 01 S 5/12 of 04/02/92 g.).

 However, the known device does not have the functions of ensuring the specified accuracy of positioning, sufficiently complete analysis, accumulation and processing of data on the state of the observed objects, planning routes of movement of moving objects. In addition, the diagnostic and control system in the known device is not sufficiently developed.

 The technical result is the expansion of the system’s functionality in terms of monitoring, control of security systems and immobilization systems, ensuring the specified accuracy of location for moving objects, as well as monitoring, control of engineering and security systems for stationary objects.

 This is achieved by the fact that in a telematics system containing a network of terminal devices located on mobile and / or stationary objects connected by communication channels to a dispatching and monitoring center, each terminal device contains a GSM bi-directional transceiver with an antenna, connected to it with bi-directional bus of the microcontroller audio interface of the face, transceiver of the satellite communication system Orbcom with antenna, GPS or Glonas receiver with antenna, interface unit with primary information sensors, unit processing of analog signals, a block for interfacing with executive devices, the main power supply unit, and the dispatch and monitoring center contains a GSM message server, an Orbcom message server, an SMS service message server and N operator workstations connected to a local network using the main system server, and also a GSM radio module with an antenna and an Orbcom radio module with an antenna connected to the GSM message server and to the Orbcom message server, respectively, in addition to the dispatch and monitoring center, additionally The WEB server and the backup server, which are connected to the local network connected by the main server of the system, are provided, as well as each movable object is equipped with a moving object immobilizer connected to the bi-directional bus of the microcontroller, and each terminal device contains a backup power supply, in addition, in each stationary the main power supply unit is made in the form of a power supply unit from an alternating current network of 220 V, and in each movable object the main power supply unit is made in the form of a power supply unit from the on-board network, except In addition, in each movable object, the main power supply can be made in the form of a power supply from the on-board network and an additionally introduced power supply from the AC 220 V.

 The essence of the invention lies in the fact that a global positioning system (Glonas or Navstar), a GSM mobile communication system, an Orbcom satellite communication system are combined into a single multifunctional monitoring system for moving and stationary objects, and the introduction of additional processing units for information received from the GPS receiver provides specified accuracy of positioning.

 Comparison of the proposed system with the closest analogue allows us to claim compliance with the criterion of "novelty", and the absence of distinctive features in the analogues - to talk about compliance with the criterion of "inventive step".

 Preliminary tests suggest the possibility of industrial use.

 In FIG. 1 is a functional block diagram of a terminal device; FIG. 2 - dispatching and monitoring center, and in FIG. 3 - systems as a whole.

 The terminal device 1 of the object serviced by the system (Fig. 1) contains blocks 2 and 3 of the audio interface (microphone and telephone) connected to the GSM transceiver 4 with an antenna, transceiver 5 of the satellite communication system Orbcom with an antenna, GPS receiver 6 or Glonas, a unit 7 for interfacing with primary information sensors (for example, security sensors), an analog signal processing unit 8, an interface unit for actuators 9, a universal immobilizer 10 for a moving object (for example, a starter relay interlock) and a microcontroller 11.

 The transceiver 4 can be performed, for example, in the form of a cellular telephone communication modem GSM GSM Siemens Module M20 standard.

 The receiver 6 can be made, for example, in the form of a navigation receiver of the satellite radio navigation system GPS NAVSTAR model Trimble Lassen LP or Rockwell Jupiter (Jupiter LP).

 As blocks 7-9 can be used nodes such as ADCs and DACs or other nodes of digital-to-analog equipment.

 The bi-directional bus of the microcontroller 11 combines the transceivers 4, 5, the receiver 6, blocks 7-9 and the immobilizer 10, as well as the power supply units 12, 13 from the alternating current main and from the on-board network of the moving object related to the main power unit, and an autonomous backup unit 14 nutrition. Additionally, the introduced power supply unit 12 can be used when the terminal device 1 is operating in laboratory conditions.

 Microcontroller 11 provides information exchange with a cellular modem - GSM transceiver 4, GPS navigation receiver 6, blocks 7-9 for pairing with primary information sensors, processing of analog signals and pairing with actuators and with blocks 2 and 3 of the audio interface.

 The microcontroller 11 can be made on the basis of two ATMEL AT MEGA 103 microcontrollers of the “8” type, one receiving and processing information received from a cellular modem — GSM transceiver 4 or 5 transceiver Orbcom, prepares information for transmission and controls the operation the entire device as a whole, while the other processes the information received from the receiver 6 GP3, from external digital and analog lines, generates and transmits commands to external lines, monitors the operation of power supplies.

 The microcontroller 11 includes RAM with a capacity of "32" Kbytes for storing operational data for the operation of processor programs, as well as non-volatile flash memory with a capacity of "4" MB for storing parameters of the operating modes of terminal device 1 and recording the log of operation of terminal device 1.

 The system dispatch and monitoring center 15 (see FIG. 2) contains a GSM radio module 16 connected to a GSM message server 17, an Orbcom radio module 18 connected to an Orbcom message server 19, an SMS service message server 20, a WEB server 21, a main server 22 , a standby server 23 and N workstations 24-1 ... 24-N operators connected to a local network using the main server 22, as well as a power supply unit (not shown in Fig.).

 As servers 17, 19, 20, 22 of center 15 and as workstations of operators 24-1. . . 24-N computers can be used type IBM PC, equipped with peripheral equipment and, if necessary, means of collecting and transmitting information. The software base of these computational tools are well-known software tools for functioning in the Windows-98 / NT environment, created, for example, based on the Borland C ++ Builder 4.0, MS Visual FoxPro 6.0 / 6.3, MapBasic 4.5 / 5.0 languages. MapInfo Professional 4.5 / 5.0 can be used as a software tool for displaying and processing geoinformation.

 As the radio module 16 can be used cellular modems SIEMENS GSM Module M20 Terminal.

 The system operates as follows.

 The operation log of the terminal device 1 records all the commands and messages received by the terminal device 1 from the dispatch and monitoring center 15, as well as transmitted from the terminal device 1 to the dispatch and monitoring center. For mobile terminal devices 1, the coordinates of the vehicle route are additionally recorded in the operation log.

 The microcontroller 11 can operate in two main modes: full power mode and low power mode ("sleep" mode).

 In each terminal device of the object serviced by the system, the microcontroller 11 transmits and receives control signals and data from the above-mentioned components of the terminal device connected to this bus via a bi-directional bus. The operation of the microcontroller 11 occurs in accordance with the program recorded in its memory. A GPS receiver or Glonas 6 receives signals from satellites of the corresponding global positioning system and calculates the coordinates of an object once a second. Coordinate data is either accumulated in the memory of the microcontroller 11, or with a periodicity specified by its program (1 time in n seconds) is transmitted to the center 15 via the GSM transceiver 4 or, in the absence of communication via this channel (for example, when a moving object leaves the GSM service area ), through the transceiver 5 of the satellite communication system Orbcom, switching to which is done in this case automatically by the appropriate commands of the microcontroller 11. Thus, the communication of the terminal device with the center 15 is not broken (ensure ) anywhere in the world.

 Through the interface unit 7, the terminal device receives signals from sensors, for example, an alarm system of an object.

 When any of the sensors is triggered, the corresponding signals are transmitted through the block 7 to the bus of the microcontroller 11 and after processing therein a message is transmitted via the GSM transceiver 4 with an antenna or the transceiver 5 of the satellite communication system to the corresponding radio module 16 or 18 of the center 15.

 Using block 8 of the processing of analog signals, the analog parameters of the object are monitored, while when the controlled voltages exceed the threshold values set in advance or the voltage values exceed the range of their permissible values, block 8 issues the corresponding signal via the bus to the microcontroller 11, which then transmits a message to the center 15, similar to how this is done when the alarm is triggered.

 Using the unit 9 for interfacing with executive devices, the microcontroller 11 can control the “16” executive devices of the object, including its security devices, according to the commands received from the transceivers 4 or 5 (GSM or Orbcom) received via the corresponding communication channels from center 15.

 Using units 2 and 3 of the audio interface (microphone and telephone), the object exchanges voice messages with center 15. In this case, communication with the center is carried out directly through GSM transceiver 4 with an antenna.

 Power supply units 13 and 14 provide continuous operation of the terminal device. The operation of these units is controlled by the microcontroller 11. In case of a malfunction of the main unit, for example, if the power supply to the object is interrupted, the power of the terminal device switches to the backup unit 14. In this case, the microcontroller 11 controls the charge and discharge of the battery of the unit 14 and, depending on the remaining battery capacity, the microcontroller 11 change the frequency of alarm messages according to the programmed algorithm, prolonging the battery life of the power supply unit 14, and therefore the entire terminal device .

 The operation of the dispatching and monitoring center 15 consists in receiving messages from a plurality of terminal devices of the system objects via the GSM radio module 16 and the Orbcom 18 radio module, accumulating, processing and analyzing these messages on the respective servers 17 and 19 with the subsequent transmission of the necessary commands, which is determined by the server program, through radio modules 16 and / or 18 to system objects. Server 20 receives short messages directly from the short message service via a copper or fiber channel. Server 21 receives and sends messages to the Internet, organizing an additional communication channel. At the same time, the main and backup servers 22 and 23 of the center provide management of the center, maintaining databases, processing GPS information, preparing electronic maps, maintaining a geographic information database, distributing information flows between the workstations of operators 24-1. .. 24-N, displaying the location of objects on electronic maps on the screens of monitors of these workstations, generating commands and messages then transmitted to system objects, distributing the transmitted information to servers 17 or depending on the selected transmission channel, GSM or Orbcom. During the work of the center, workstations of operators 24-1. . . 24-N are used to provide monitoring and servicing by each operator of the corresponding part of the network of terminals of system objects, while operators transmit messages to objects and, if necessary, establish two-way voice communication with the object.

 Thus, the construction of a telematic system in the manner described above allows you to expand its functionality and ensure the achievement of the technical result.
