Description

The invention relates to the field of traffic regulation and can be used to identify vehicles (TS).

The known "Device for detecting vehicles near bus stops" according to US patent No. 5382953 dated 04/14/94 was published in the journal "Inventions of the World", 1996, No. 3, p. 19), in which, using a sensor, the device sign detection and control a vehicle is detected. However, this device has low adaptability.

Also known is a "Device for identifying cars at a monitoring station" according to patent WO No. 9613023 of 10.20.95 (published in the journal "Inventions of the World", 1997, No. 3, p. 28). The specified device contains at the monitoring station a video camera and a lighting device forming an optical image on the surface of passing cars. The resulting image after processing is used to determine the height of the cars. The disadvantage of this device is a narrow range of recognizable vehicle parameters.

The well-known "Telematics system for a vehicle" according to the patent for the invention of the Russian Federation No. 2207262 C1 dated October 21, 2002. The system contains a common multiplex bus and electronic modules equipped with interfaces, some of which are connected with the functional organs of the vehicle and identify the state of these organs and their management. There is a controller for the local information network of the TS, a controller-converter of the data exchange protocol, a unit for receiving and transmitting data, for example, a terminal of a cellular mobile network. The security and anti-theft subsystem includes its own controller, interfaces with electronic units connected to the functional bodies of the vehicle to provide protection and protection against theft, and a remote user identification unit of the vehicle, consisting of contactlessly connected wearable part, for example, a transponder card, and a transportable part. In addition, a control data reading unit, a comparison unit, a unit for recording the controlled parameters of deviations from the standard modes and a unit for recording the initial data about the driver and the vehicle in the memory of the wearable part of the remote user identification unit are introduced into the system. The movable part of this block is made with the possibility of entering into it the controlled parameters of deviations from the standard modes and recording them in the memory of the wearable part of the remote user identification block.

The disadvantages of this system are the need to stop the vehicle at the checkpoint for the period of checking and exchanging information, the limited number of monitored vehicles, the need for authorization by the user of the system to perform remote control operations by government officials (for example, the road guard service), and the lack of equipment for state stationary points, designed to identify and control the vehicle with this system.

The closest analogue is the "Vehicle Identification System" according to the patent for the invention of the Russian Federation No. 2295779 C1 of September 23, 2005, containing "k" control points (where k is more than 2), interrogators installed at each control point, and a transponder placed on each motor vehicle, exchanging information with each other via a radio channel, with each interrogator containing a series-connected transmitter, an isolation element and a directional antenna, as well as a receiver whose input is connected to the second output of the element The decoupling element, each transponder contains a directional antenna connected in series, the decoupling element and a receiver connected to the transmitter, the output of which is connected to the second input of the decoupling element, as well as a code number memory element, and each interrogator additionally contains a video camera, the outputs of the cameras through the first matching the unit is connected to the first input of the computer installed at each control point, the second input of which is connected to the outputs of the interrogator receivers through the second I agree I block, the first output of the computer is connected to the inputs of the respective transmitters of the interrogators through the third matching block, and the second output of the computer through the third matching block is connected to the inputs of the cameras, while the interrogators are located above the road so that the radiation pattern of each of the directional antennas does not go beyond the limits of the corresponding row of roads, the computers of the checkpoints are connected to a local network, and the directional antennas of the transponders are located in the upper part of the transport medium CTBA so that the directivity pattern covered interrogator disposed over this next road.

The disadvantages of this system are:

the need for 2 checkpoints to determine the speed of the vehicle, and the average speed of the vehicle on the segment of the road between these control points is determined, and not the actual one at the time of passing the control point;

the inability to monitor the current coordinates and speed of the vehicle at times when it is outside the service area of the checkpoint, as well as the rapid detection of vehicles, for example, being stolen.

The technical result of the invention, to which the alleged invention is directed, is to expand the functionality of the vehicle recognition system.

The technical result is achieved by the fact that a vehicle identification system is proposed comprising a dispatch center, control points and airborne modules. An on-board module installed on each vehicle and a control point exchanging information with each other over the radio channel at the time of passing the vehicle under the interrogator and at a certain frequency (predefined 1 ... 10 min) —with the control center via a wireless modem. Dispatch center (DC) contains a server connected to a device for storing a database, a terminal and modems for communication with on-board modules and control points. Each on-board module contains a microcontroller connected to a navigation receiver, for example, GLONASS and / or GPS, a storage device, a motion sensor, a short-range transceiver, for example, based on DSRC (Dedicated Short-Range Communications) technology, and a wireless modem, for example, GSM / GPRS. The on-board module wireless communication terminal provides GPRS exchange with the control center, and the short-range transceiver - radio communication with the corresponding interrogator of the control point. Each interrogator contains a series-connected transmitter, an isolation element and a directional antenna, as well as a receiver whose input is connected to the second output of the isolation element.

Each interrogator further comprises a video camera. The outputs of the cameras through the second matching unit are connected to the first input of the computer checkpoint. The second input of the computer is connected to the outputs of the receivers of the interrogators through the third matching unit, the first output of the computer is connected to the inputs of the respective transmitters of the interrogators through the first matching unit, and the second output of the computer through the first matching unit is connected to the inputs of the cameras. Interrogators are located above the rows of the road so that the radiation pattern of each of the directional antennas does not go beyond the corresponding row of the road. The directional antennas of the transponders are located at the top of the vehicle so that the radiation pattern covers the interrogator located above this row of roads.

Figure 1 presents a structural diagram of a vehicle recognition system.

Figure 2 presents, respectively, the structural diagrams of the interrogator and the on-board module. The control point 1 shown in FIG. 1 contains a computer 2, a first matching unit 3, a second matching unit 4, a third matching unit 5, interrogators 6 according to the number of rows of the trunk and the modem 10.

The dispatch center 23 shown in FIG. 1 comprises a modem 24, a server 25, a terminal 26, a modem 27, and a database storage device 28.

Figure 1 shows the radiation patterns of 8 and 9 directional antennas, respectively, interrogators 6 and airborne modules 7.

Figure 2 presents the structural diagram of the interrogator 6, containing the video camera 11, the transmitter 12, the receiver 13, the isolation element 14 and the directional antenna 15, and the structural diagram of the vehicle on-board module 7 containing the directional antenna 16, the transceiver 17, the GLONASS navigation receiver and / or GPS 18, microcontroller 19, motion sensor 20, storage device 21 and modem 22.

The vehicle identification system operates as follows. An on-board module 7 (FIG. 2) is installed on each vehicle, containing a microcontroller 19 connected to a GLONASS and / or GPS 18 navigation receiver, a storage device 20, a motion sensor 21, a short-range transceiver 17, for example, using DSRC technology, and a modem 22 wireless communications, for example, GSM / GPRS. The wireless communication modem 22 of the airborne module 7 provides GPRS exchange with the server 25 of the dispatch center 23 through the wireless communication modem 27 (Fig. 1), and the short-range transceiver 17 communicates with the corresponding interrogator 6 of control point 1. At control points 1 above the road (highway) interrogators 6 are placed above the rows of the road so that the radiation pattern 8 of each of the directional antennas 15 does not go beyond the corresponding row of the road (Fig. 1). The directional antenna 16 of the short-range transceiver 17 is located in the upper part of the vehicle so that the radiation pattern 9 covers the interrogator 6 located above this near the road. The radiation patterns of directional antennas 15 and 16 are selected from the conditions of unambiguous selection of the vehicle. The on-board module 7 receives commands from the interrogator 6 a request signal to turn on the short-range transceiver 17, which after receiving the request signal transmits a response signal containing a code number, individual for each vehicle and stored in the storage device 20.

Checkpoint 1 (figure 1) contains a computer 2 connected to three matching blocks 3, 4 and 5 and a modem 10 for communication with the modem 24 of the control center 23. Matching blocks 3, 4 and 5 are connected to the interrogators 6, the number of which corresponds to the number rows of roads (highways) over which they are installed. Each interrogator 6 contains (Fig. 2) a series-connected transmitter 12, an isolation element 14 and a directional antenna 15, as well as a receiver 13, the input of which is connected to the second output of the isolation element 14 and a video camera 11. The inputs of the video camera 11 and the transmitter 12 are connected to the corresponding ( serial number of the interrogator 6 of the control point 1) by the output of the first matching unit 3. The output of the transmitter 13 is connected to the corresponding input of the third matching unit 5, and the output of the video camera 11 is connected to the corresponding input of the second matching unit four.

The transmitter 12 (figure 2), transmits, upon a command from computer 2, through the first matching unit 3, request signals to start operation of the on-board module 7 through an isolation element 14 and a directional antenna 15. The receiver 13 receives a response signal from the on-board module 7 containing information about the vehicle’s code number and through the third matching unit transmits it to computer 2. Computer 2 through the first matching unit 3 generates a request for the video camera 11 to start working on this near the road for visual fixation of the vehicle vehicle and its license plate. Information from the video camera 11 through the second matching unit 4 enters the computer 2, where it is stored and visualized. Signals containing information on the vehicle code numbers from all receivers 13 of the interrogators 6 through the third matching unit 5 are sent to computer 2, which checks their compliance with the vehicle license plate received from the video camera. The vehicle code numbers and the time of their fixation by means of modems 10 and 24 are transmitted to the server 25 of the dispatch center 23. The dispatch center 23 contains a server connected to the modem 24, terminal 26, modem 27, and a database storage device 28 (Fig. 1). Information from on-board modules 7 (code number, time, coordinates, vehicle speed) is received from server 25 from modem 27. As a result of its comparison with the information from the device for storing the database 28 and with the operational information received from the terminals 26, the server 25 forms and sends to the checkpoint a confirmation that the vehicle monitored according to the monitoring data with the given code number and license plate at the indicated time was in the area of this checkpoint (or service information, for example, the vehicle is being stolen or wanted).

The work of the checkpoint is possible both in stand-alone mode and in the presence of an operator.

All system blocks are made of standard elements according to known schemes. For example, matching blocks are made in the form of controllers that convert the incoming information to a form convenient for processing by a computer, the functioning program of which is standard for burglar alarm systems and access systems.

Using this system allows you to:

to ensure continuous monitoring of the vehicle not only at the control point, but also along the entire route of its movement thanks to a signal periodically transmitted by the on-board module to the dispatch center containing information about the code number and navigation parameters of the vehicle;

to identify vehicles at the checkpoint with fake (or unreadable) license plates, thanks to the constant code number in the on-board module memory and information about the vehicle located in the device for storing the data base of the data center;

to obtain information about the route of the vehicle, for example, being stolen or wanted, until the time it crosses the checkpoint, thanks to the navigation information transmitted from the on-board module to the device for storing the data base of the data center;

receive information about the vehicle’s high-speed mode of movement both in the area of the checkpoint and on the entire route.
