Description

The invention relates to radio-search technologies used to combat theft of vehicles (HARDWARE), and is intended to determine the location of the vehicle and ensure the operational search for stolen vehicles (TCB).

A known monitoring system, information service and protection of moving and stationary objects according to patent RU No. 2174923, B60R 25/00, containing a telephone communication network and data transmission connected to a paging communication network, including a subscriber data transmission unit and associated via radio subscriber receivers installed on the objects of subscribers of the system, each of which is connected via a controller with sensors of unauthorized impact, with the launch unit of the subscriber transmitter and with the control unit security system device, for example, an immobilizer connected to the security system actuator and configured to turn on and off the security system actuator, for example, an immobilizer, when receiving special codes via a paging communication network, as well as a geographically distributed relay-and-direction finding network, consisting of from radio direction finders installed on traffic lights, city lighting poles, roofs of buildings and other stationary installations objects made with the possibility of receiving code parcels from a subscriber transmitter when the carrier object is located in the coverage area of the given radio direction finder and with the possibility of transmitting received messages to at least one of the base stations of the geographically distributed network of base stations, as well as information centers, each of which contains a series-connected information receiving unit, a primary digital processing unit, a secondary processing unit, an information message generation unit, and voice message rider associated with a geographically distributed network of centers for operational response, a unit for receiving and processing messages from external information sources, the inputs of which are connected via communication channels to external information sources, the first output of which is connected to the corresponding input of the secondary processing unit, and the second output to the second input of the information message generation unit, the registration unit and the display unit, the inputs of which are connected to the corresponding outputs of the primary unit digital processing, and the outputs - with the corresponding inputs of the secondary processing unit, made with the possibility of determining the coordinates of objects from the totality of data on the location of the relay-direction finding radios, which received signals from subscriber transmitters whose powers exceed a predetermined level, and the measured values of the received signal powers and bearings on them , as well as a dispatch center, which includes a series-connected additional receiving unit, an additional primary digital image unit otki, a block for generating information messages of a dispatch center and a voice driver for a dispatch center, the output of which is connected to a geographically distributed network of centers for operational response, each of which is capable of recording and recording voice messages, as well as with the possibility of determining the location of forces and means of rapid response - pedestrian outfits and patrol cars - on the road network and with the ability to call the closest to the radiating subscriber to the transmitter of a foot patrol or patrol vehicle and controlling them in the process of approaching an object emitting an alarm, while the quick response means are capable of measuring the polar coordinates of the subscriber transmitter emitting a signal, while each of the base stations is connected to the corresponding input of an additional receiving unit located in the dispatch center, and each additional output of the information message block of the dispatch center is connected to input b eye receiving corresponding information center, the information center in each block forming the second output is connected to the information messages paging network and the second output driver voice messages - to a telephone network and data communication.

The disadvantages of this system are related to the difficulty of locating on the ground - especially in urban conditions - a sufficiently large number of radio direction finders and base stations that could provide continuous coverage of a given territory (city, region). This requires large capital expenditures and coordination with government agencies that control the use of frequencies, allocation of land and capital construction.

To address this drawback directed technical solution according to patent RU No. 2228861, B60R 25/00, G08B 25/08.

The regional anti-theft alarm system described therein contains sensors installed on the protected vehicle and a subscriber receiver connected via a paging network to the regional telephone network, the outputs of which are connected to the controller connected to the transportable part of the user identification unit and to the transceiver module of a standard cellular mobile network. A subscriber receiver may include a receiver of the global satellite radio navigation system (GPS-receiver), which provides highly accurate autonomous measurement of the coordinates of the protected vehicle (or TCB). The relevant outputs of the controller are connected to executive devices of the security system, which are capable of blocking the movement of the TCB when the engine blocking commands are received from the subscriber receiver and / or from the transceiver module of the standard cellular mobile communication network, and an autonomous transmitting device connected via radio to installed objects urban infrastructure with radio direction finders, which are part of a specialized data network containing the central point of control of the specialized network connected to the relay-direction finders, the output of which is connected to a data reception unit installed in the dispatch center, the output of which is connected through a series-connected digital information processing unit and the central information message generation unit to the dispatch communication unit configured to transmit information messages on dedicated channels of the regional telephone network and / or through a standard mobile cellular network with bind to a network of information centers and to a network of quick response centers associated with the forces and means of quick response - foot patrols and patrol cars, providing for the interception of fusion vehicles.

The use, along with a specialized data transmission network, of standard paging and cellular mobile communication networks can significantly expand the coverage of the radio search system and ensure the continuity of the coverage area. In addition, in segments in which the coverage areas of a cellular mobile communication network and a specialized data transmission network overlap, the reliability and quality of information delivery increases, which ultimately leads to an increase in the efficiency of interception of focal points by forces and means of quick response. This is the advantage of this system.

However, this system is not free from disadvantages. The fact is that standard paging networks and cellular mobile networks, in particular, GSM standard, are vulnerable to deliberate (intentional) interference that an attacker can use. So, according to the advertising information of the Israeli company NetLine, the C-Guard LP jammer, mass-produced by this company, with an average radiation power of (5-50) mW and a mass of not more than 0.6 kg provides effective blocking of subscriber terminals of standard cellular mobile networks in a radius of ( 5-80) m around you. Currently, an increasing number of thefts occur with the use of such jammers.

To eliminate this drawback, the method of radio search and interception of TCB according to patent RU No. 2253578, B60R 25/00, G08B 25/10 is directed, in which, with the help of security detectors, an intruder is penetrated into a protected vehicle, a high-frequency signal is emitted using an autonomous transmitting device, and Using a transceiver module, a high-frequency signal using one of the standards of a cellular mobile network generates alarm notifications and converts them into code messages, which modulate these high-frequency signals, transmit modulated high-frequency signals, carrying alarm notifications, to the dispatch center, respectively, through a geographically distributed relay-radio direction finding network and a standard cellular mobile network, generate test signals in the control center of a standard cellular mobile communication network and transmit them according to a standard cellular mobile communication networks, receive the indicated test signals on board the guarded vehicle, select alarm notifications in the control center and carry out their digital a process by which the fact of hijacking and movement of the vehicle over the road network is recognized, the identification signs of the vehicle and its current location are determined on the map-scheme of the road network, after which initial and current external target designations with location data are formed and transmitted to the fast response vehicle and identification signs of the TCB, and, if necessary, remotely block the movement of the TCB, while transmitting alarm notifications via a geographically distributed relay and radio direction finding These control on board the TCB the coincidence of the sequence of binary symbols in the alarm notices transmitted and received over the air, and in the absence of the indicated coincidence, a reception failure signal is generated via the relay-radio direction finding network, and when receiving test signals received via a standard cellular mobile network, average for a given time interval, the signal-to-noise ratio values are compared with a predetermined threshold and when the measured average signal-to-noise ratio decreases to a predetermined at the horny level and with the simultaneous presence of a reception disruption signal via the relay-radio direction finding network, a sequence of commands is generated on board the TCB that affect the blocks of movement blocking of the TCB, causing it to gradually stop, after which the object terminal device is activated, by means of which alarms are emitted in authorized devices burglar alarms in the ranges of frequencies and capacities, direction-finding alarms from the sides of the vehicle for quick response and use these bearings together with the current external target designation for controlling the movement of the vehicle rapid response in the process of intercepting the TCB.

The method described above is a technology for radio search and tracking of TCB, which allows to increase the effectiveness of the actions of the participants of the “interception” operation (fast response vehicle crews and control center personnel) when hijackers use means of setting up intentional interference, in particular, jamming means of GSM communication channels, paging communication channels, as well as when setting special interference to global satellite radio navigation systems, making it impossible to accurately measure the coordinates of the TCB.

However, like all other technical solutions described above, this method is difficult to implement, since it requires the creation of a specialized geographically distributed network and the installation on board the vehicle and in dispatch centers of rather sophisticated specialized equipment.

The present invention is aimed at significantly simplifying the practical implementation of the technology of radio search for TCB using a fast response vehicle due to a more complete use of the capabilities of modern cellular mobile networks, primarily GSM networks.

The subject of the present invention is a method of radio search for TCB, in which the guarded vehicle is equipped with a mobile mobile terminal that contains a SIM card, after the fact of theft of the vehicle is established, a message about the fact of theft of the vehicle from the vehicle’s mobile phone or from the tracking center is sent via the cellular mobile network, receive this message by mobile cellular terminals installed on the TCB and in the dispatch center for quick response, activate the beacon transmitter covertly installed on board the TCB, emit With the help of a beacon transmitter, alarms in the dispatch center for quick response receive information about the location of the TCB, on the basis of which they form and transmit to the crews of the fast response vehicles target designation, allowing to bring the quick response vehicles to the TCB at distances that provide direction finding radiation of the beacon transmitter from the sides of the fast response vehicles , direction finding the indicated beacon transmitter from the sides of the rapid response vehicle and using these bearings to find the TCB, and remember the message about the theft of the vehicle sent from the vehicle’s mobile phone or from the tracking center is stored in the memory of the cellular mobile communication network, and the cellular mobile communication terminal installed on the TCB is kept in standby mode with the power of the cellular mobile communication terminal turned off, turning off the standby mode in predetermined moments for the time required to establish two-way communication with base stations of the cellular mobile network, during which a message about the theft of the vehicle, stored from each base station, is sent in the memory of the cellular mobile network, take it installed on the TCB mobile cellular terminal, and then prohibit the transfer of the mobile mobile terminal into standby mode, in the dispatch center quick response, the user of the vehicle or in the tracking center receive a message about the theft of the vehicle and form a request according to which the quick response dispatch center receives information about the location of the TCB for the formation of target designations by determining the location of the SIM card in the cellular mobile communication network and accounts of the error value for determining this location, according to the value of the mentioned error, determine the border of the TC zone in the fast response dispatch center and report its location to the fast response vehicle, and the activation signal of the beacon transmitter is sent from the board of any fast response vehicle after crossing the specified border.

Particular features of the invention are as follows.

At the end of a predetermined period of time after sending from each base station a message about the theft of the vehicle and in the absence of a request from the dispatch center for quick response, from the vehicle user or from the tracking center to determine the location of the SIM card in the cellular mobile network, it is sent over the cellular mobile network communication message about the absence of a request, receive it by the mobile cellular communication terminal and put the mobile mobile communication terminal in standby mode.

A request from the dispatch center for quick response, from the user of the vehicle or from the tracking center to determine the location of the SIM card in the cellular mobile network is sent to the operator center of the mobile mobile network by pressing a button on the Internet portal or by sending an SMS message to the number received when registering a SIM card in a cellular mobile network.

The stored message about the fact of theft of the vehicle is deleted from the memory of the cellular mobile communication network upon command from the vehicle of the fast response after direction finding of the beacon transmitter.

A message about the theft of the vehicle, transmitted to the dispatch center for quick response, to the user of the vehicle or to the tracking center, is generated in the cellular mobile communication terminal installed on the TCB, after the prohibition of its transfer to standby mode and this message is transmitted via the cellular mobile communication network.

The objective of the invention is the creation of a radio search technology for stolen (stolen) vehicles, effective even in cases where the hijackers physically and / or using electronic jamming managed to neutralize the security and anti-theft system of this vehicle and other radio search systems.

The provided technical result consists in using for the designation of targets transmitted to the rapid response vehicle, a specialized LBS service (Location Base Services) to determine the location of the SIM card of a subscriber of a cellular mobile communication network installed on the TCB in a cellular mobile communication terminal. The proposed implementation of the inventive method is simple and affordable for a wide range of TS users.

The essence of the invention is illustrated in figure 1 and figure 2.

Figure 1 presents the General structural diagram of a radio search system that implements the claimed method of radio search TCB.

Figure 2 presents the structural diagram of the on-board module installed on board the guarded vehicle, which in the case of theft is the subject of a radio search.

In Fig. 1 and Fig. 2, the following notation is used: 1 - SIM card, 2 - mobile cellular communication terminal, 3 - mobile cellular communication operator center, 4 - on-board module, 5 - timer, 6 - self-contained power supply, 7 - receiver, 8 - command generator, 9 - antenna switch, 10 - dispatch center for quick response, 11 - beacon transmitter, 12 - direction finder.

The radio search system shown in FIG. 1 and FIG. 2 includes an on-board module 4, covertly mounted on a guarded vehicle, a cellular mobile communication network with a cellular mobile communications operator center 3, capable of providing a specialized LBS SIM location service -cards 1 of the subscriber registered in the cellular mobile communication network, a quick response dispatch center 10, connected to the cellular mobile communication operator center 3 and configured to transmit target designations to the vehicle three response. On each fast response vehicle there is a direction finder 12, configured to receive alarms emitted by the beacon transmitter 11 of the on-board TCB module 4.

In addition to the beacon transmitter 11, the on-board module 4 (FIG. 2) includes a timer 5 and an associated autonomous power supply 6, made, for example, based on a relay and a miniature battery (battery), as well as a mobile terminal 2 with SIM a card 1 configured to receive and transmit messages over a cellular mobile communications network, a receiver 7, a command shaper 8 and an antenna switch 9 with a transceiver antenna configured to radiate alarms and receive signals from the onboard fast response vehicle but activation. The information input of the receiver 7 is connected to the output of the antenna switch 9, the first output of the receiver 7 is connected to the information input of the mobile terminal 2, and the second output is connected to the information input of the command shaper 8. The power input of the receiver 7 together with the power input of the cellular mobile communication terminal 2 and with the power input of the command shaper 8 are connected to the second output of the autonomous power supply 6, the third output of which is connected to the power input of the beacon transmitter 11, the output of which is connected to the information input of the antenna switch 9. In this case, the first, second and third outputs of the shaper 8 teams are connected, respectively, to the second input of the autonomous power source 6, to the control input of the beacon transmitter 11 and to the control a course antenna switch 9.

The key procedure in the considered method of radio search for the TCB is the implementation of a specialized LBS-service for determining the location of SIM-card 1, installed in terminal 2 of cellular mobile communications. If the cellular mobile communication terminal 2 is turned off, it is impossible to determine its location. But even the short-term activation of the mobile terminal 2 allows you to locate its SIM card 1. The location of the mobile terminal 2 is established by implementing the standard MPS procedure (Mobile Positioning System) - analysis of the parameters of signals received by the base stations of the mobile cellular network in the operator 3 mobile cellular center. The accuracy of determining the coordinates of SIM card 1 is several hundred meters and may vary depending on its location. So, for example, in St. Petersburg in places of dense urban development, it is no more than 300 m, and closer to the outskirts of the city - (700-800) m (www.spbit.ru/news/n7441).

In order to use the aforementioned LBS service, the user of the vehicle - the owner of the mobile terminal 2 with SIM card 1 - needs to register with the regional mobile operator, after which he receives a special number. He can transfer this number to other users of his vehicle, in particular, to the tracking center at the insurance company in which his vehicle is insured, as well as to the operator of the dispatch center 10 quick response. After that, by pressing a button on the Internet portal or sending an SMS message to this special number, the user of the vehicle (operator of the tracking center) and / or the operator of the dispatch center 10 quick response receive in text form or graphically (a specific segment of the electronic map is drawn) information about the volume where the mobile terminal 2 is currently located with SIM card 1 installed in it. The accuracy of determining the location of SIM card 1 in the cellular mobile network using the MPS procedure is indicated.

The LBS service for determining the location of SIM card 1 of a subscriber of a cellular mobile network by analyzing the parameters of signals received by several base stations is a new type of specialized information service provided by regional cellular mobile communication operators. So far, this LBS service is being provided only in large cities: Moscow, St. Petersburg, Irkutsk.

So, on the site www.spbit.ru it is reported that the St. Petersburg branch of MTS launched a test operation of a set of services based on the location of the SIM card 1 of a mobile cellular subscriber, under the common brand name "MTS-Search". In Moscow, the commercial operation of MTS-Search began in April 2005. Now for all services provided under this brand, a GSM standard network is used.

In particular, the specialized Avtoskop service is offered, thanks to which users can get information about the current location of their vehicle. To do this, you can use a standard mobile phone, or order a special terminal 2 of a mobile cellular communication containing SIM card 1.

With regard to security systems, this service is described, for example, in the magazine "Master 12 Volt", November 2006, p. 46-51 (www.master12v.ru).

The transmission of target designations and control of the rapid response vehicle from the dispatch center 10 quick response can also be carried out using the same GSM network.

The direction finder 12, which carries out the direction finding of the beacon transmitter 11 installed on board the TCB from the sides of the rapid response vehicle, is used, for example, in the well-known Lojack radio search system (www.lojack.ru).

Autonomous power supply 6 contains a battery (accumulator) and a relay device with several relays controlled by commands from timer 5 and from shaper 8 teams.

In standby mode, the battery is connected only to timer 5, which is a regular electronic clock (alarm clock). Accordingly, the power consumption is minimal and the battery can work in this mode for several years.

In operating mode, a mobile cellular communication terminal 2, a receiver 7 and a command shaper 8 are also connected to the battery (to the second output of the autonomous power supply 6) (beacon transmitter 11 is turned off). Accordingly, the consumption of on-board module 4 is increasing. But due to the short duration of the session (about one minute) and the small number of inclusions of these devices (about once a day), the energy consumption is small. This ensures a sufficiently long (about one year) battery life, which also increases the stealth of the on-board module 4.

At the final stage of the UTS radio search, a beacon transmitter 11 is connected to the battery (to the third output of the autonomous power supply 6). Consumption increases sharply. But this happens already when the search for the TCB is nearing completion, and the airborne module 4 has almost completed its task.

The command generator 8 is a digital circuit designed to convert the activation code contained in the signal received by the receiver 7 into commands for connecting power to the beacon transmitter 11 and activating the radiation on the air.

Thus, all the nodes and technologies used to implement the method in question are known and applied in practice. Therefore, the possibility of practical implementation of the radio search system presented in figure 1 and figure 2, is not in doubt.

The claimed method of radio search TCB is implemented as follows.

The user of the vehicle (for example, the owner of the vehicle or his authorized representative), acquires SIM card 1 from the regional cellular mobile operator and, having registered it with this operator, receives a special number for the provision of the LBS service.

The registration rights of SIM card 1 can be transferred to another user of the vehicle, for example, to one of the family members of the vehicle owner or to the tracking center at the insurance company in which the vehicle owner has registered his vehicle. The insurance company is financially interested in returning it to the user of the vehicle in the event of theft or theft of the insured vehicle. The proposed method of radio search TCB provides such an opportunity.

For this, the user of the vehicle discreetly installs a mobile mobile terminal 2 in his / her vehicle equipped with the aforementioned SIM card 1. In this case, the user of the vehicle becomes a user of the aforementioned specialized LBS service - by determining the location of SIM-card 1 in the cellular mobile network. Having discovered the fact of theft, for example, not finding his vehicle in the parking lot, the user of the vehicle sends to the special number that he received when registering SIM card 1 a message about the fact of theft of the vehicle (for example, an SMS message) containing the identification code of this SIM card 1. If the vehicle user has access to the Internet, a message can be sent by pressing a button on the Internet portal.

For definiteness, let us say that communication is carried out over a standard cellular mobile communications network via SMS messages. SMS message about the fact of theft of the vehicle sent by the user of the vehicle is transmitted to the operator center 3 of the mobile mobile communication and is recorded in it, that is, it is stored and transmitted for storage in the cellular mobile communication network.

It should be noted that the fact of theft can also be false (for example, another user of the vehicle took the vehicle). Moreover, with real vehicle theft, the hijacker might not have turned off all anti-theft blocks. As a result, the vehicle will not be able to move more than a hundred meters from the parking lot and will be quickly found by the vehicle user. Therefore, the user of the vehicle should always be able to refuse to register a previously submitted message about the theft. For simplicity of presentation, in the materials of this patent the case of the refusal of the vehicle user to register the fact of theft will not be considered.

After registration, an SMS message about the theft of the vehicle must be sent through the base stations of the cellular mobile communication network to the board of the TCB. On-board module 4 on board the TCB in the coverage area of the regional cellular mobile communication network (which includes mobile cellular communication terminal 2) must receive this SMS message and respond to it.

However, most of the time the on-board module 4 is in standby mode, when from all the nodes of the on-board module 4 only the timer 5 receives the supply voltage - from the first output of the autonomous power supply 6 - and the receipt of SMS messages is impossible.

The time and frequency of connecting the second output of the autonomous power supply 6 to the cellular mobile communication terminal 2, to the receiver 7 and to the command shaper 8 sets a timer 5. To connect the second output of the autonomous power supply 6 to the above nodes of the on-board module 4, timer 5 sends the corresponding command to the first input of an autonomous power supply 6. This command switches the relay, which is part of an autonomous power source 6. In this case, the battery included in the autonomous power supply 6 is connected to the above-mentioned nodes of the on-board module 4.

Accordingly, the mobile cellular communication terminal 2 and the receiver 7 enter the operating states, and the command generator 8 switches to the standby mode, in which it does not generate any commands, but is ready to receive the activation code from the receiver 7.

In particular, in the standby mode of operation from the shaper 8 commands to the antenna switch 9 is not supplied control signals. The relay windings in the antenna switch 9 are de-energized. In this state, the antenna switch 9 provides the connection of the transceiver antenna to the receiver 7.

After the transition to the operating state, the mobile terminal 2 sends a signal containing the identification code of the SIM card 1 to the base stations of the cellular mobile network. Having received a signal with the SIM card identification code 1 from the cellular mobile communication terminal 2, the cellular mobile network base stations request the cellular mobile communication operator center 3 for the presence of a registered SMS message about the theft of the vehicle, which must be transmitted to the mobile cellular terminal 2 communication.

If the mobile operator’s call center 3 has a previously registered SMS message about the theft of the vehicle related to the received SIM card identification code 1, the mobile call center 3 sends this SMS message to the UTS via the base stations of the cellular mobile network . The specified SMS message about the fact of theft of the vehicle arrives at the terminal 2 of the mobile mobile communication, which sends to the autonomous power source 6 a command prohibiting the management of the autonomous power source 6 from the timer 5. In addition, the terminal 2 of the mobile mobile communication generates a response SMS message confirming receiving a message about the theft of this vehicle. This SMS message over the mobile cellular communication network is transmitted to the user of the vehicle (and / or to the tracking center) and to the dispatch center 10 quick response.

Having received an SMS message from the cellular mobile terminal 2, the vehicle user (and / or the tracking center operator) or the quick response dispatch center 10 send a request for the implementation of the aforementioned LBS service to the mobile cellular operator center 3 - by determining the location in the SIM network cards 1.

It should be noted that there may be reasons not to send a request for the provision of LBS services. For example, the hijacker may try to negotiate with the user of the vehicle to return the vehicle for a certain fee. In this situation, the mobile mobile operator center 3 waits for a predetermined time for receiving the request, but, without waiting for it, sends a message about the absence of the request to the mobile mobile terminal 2 in the TCB. After receiving this message, the mobile terminal 2 again puts the on-board module 4 into standby mode.

If, nevertheless, the specified request is received by the operator center 3 of cellular mobile communications, then it implements the LBS service. Information about the location of the SIM card 1 registered in the cellular mobile network (and, accordingly, the TCB) is sent over the air or via the wired communication channel from the cellular mobile communication operator center 3 to the quick response dispatch center 10 and to the vehicle user (and / or to the tracking center ) When using the Internet portal, this information can be represented as a map segment, within which there is a TCB. The text of the SMS message can contain street names, house numbers, and other information that allows you to quickly (but with low accuracy) evaluate the location of the TCB.

In accordance with the information received, in the dispatch center 10 quick response form and transmit to the crews of the vehicle rapid response target designation - that is, indicate the boundaries of the zone within which there may be a TCB. The accuracy of target designation is determined by the error in determining the location of the search object in the cellular mobile network. The indicated error defines the boundary of the TCB search zone. As noted above, this error is several hundred meters.

Next, a command is given to move the rapid response vehicle to the specified zone. After a fast response vehicle enters the search area, an activation command for the beacon transmitter 11 installed on board the TCB is sent from the board of this quick response vehicle. This command is received by the transceiver antenna of the airborne module 4 and through the antenna switch 9 enters the receiver 7, which transmits it to the control input of the command shaper 8. On this command, the shaper of 8 teams sequentially generates the following commands:

- a command for connecting power to the beacon transmitter 11. This command is supplied to an autonomous power supply 6. According to this command, the relay switches, as a result of which the corresponding output of the autonomous power source 6 is supplied with power to the beacon transmitter 11;

- a command to switch the antenna switch 9. This command is sent to the antenna switch 9, and through it the antenna switch 9 disconnects from the receiver 7 the transceiver antenna of the airborne module 4 and connects it to the beacon transmitter 11;

- the activation command of the radiation supplied to the beacon transmitter 11. By this command, the beacon transmitter 11 through the antenna switch 9 and the transceiver antenna of the on-board module 4 starts to broadcast alarms.

At the final stage of the search operation, the direction finders 12 installed on board the rapid response vehicle play a key role. They determine the radiation of the beacon transmitter 11, that is, they determine the direction to the radiation source. For this, the signals of the activated beacon transmitter 11 are received by direction finders 12, processed and displayed as a bearing on the radiation source. The bearing can be displayed, for example, using the arrow on the screen of the liquid crystal indicator, showing the desired direction of movement on the TCB. Using these bearings, fast response vehicles move in the direction of the TCB, gradually narrowing the search ring. As the distance between the rapid response vehicle and the TCB decreases, the linear error of direction finding of the radiation source decreases, which allows one to quickly find the TCB.

At the end of the search for the TCB and its stop, the emission of alarms by the beacon transmitter 11 should be stopped. This is accomplished by submitting from the vehicle a quick response a special SMS message arriving at mobile cellular communication terminal 2 and cellular mobile communication operator center 3.

According to this SMS message, the mobile cellular communication terminal 2 generates and transmits a command to the autonomous power supply 6, by which the autonomous power supply 6 disconnects the power from the beacon transmitter 11 (stopping the emission of alarms). Then the power is disconnected from the shaper 8 teams, the receiver 7 and the terminal 2 of the cellular mobile communication. The power remains connected only to timer 5. On-board module 4 returns to standby mode.

The same special SMS message received at the quick response center 3 forms a command to erase a registered SMS message about the theft of this vehicle. However, another option is also acceptable for the operation of a cellular mobile communication operator center 3, in which a command to erase an SMS message on the fact of theft of a given vehicle registered in the cellular mobile network is sent from the fast response vehicle immediately after direction finding by the TCB.

As follows from the above description, the proposed method of radio search has a number of specific features compared to traditional methods described, for example, in patents RU No. 2228860, B60R 25/00, B60R 25/10, G08C 13/00; RU No. 2240938, B60R 25/00, G08B 25/00; RU No. 2244642, B60R 25/00; RU No. 2264937, B60R 25/00, G 08R 25/00.

These features are as follows:

1. The initial location of the TCB (target designation) is not carried out using on-board navigation aids, for example, a GPS receiver and / or a specialized geographically distributed relay-and-direction finding network, but through the use of a specialized LBS service of a regional cellular mobile operator, location of a SIM cards 1.

2. On-board module 4 on the TCB is activated extremely rarely (about once a day) and for a short time (about one minute). This allows you to use on board a guarded vehicle one or more small-sized autonomous power sources 6, made, for example, on the basis of a relay device and a miniature battery located in the same housing with other nodes of the on-board module 4 (figure 2). Accordingly, the high secrecy of the installation of the on-board module 4 is ensured, and this installation does not require special training from users of the vehicle.

3. Due to the compactness of the on-board module 4, as well as due to the lack of lead wires, it can be installed, for example, under the skin in the vehicle compartment - like a bug. Such duplicating "bugs" can be installed in the vehicle a lot. Thus, the maximum concealment of the installation of the onboard module 4 is ensured. Moreover, even after disassembling the TCB into parts, the attacker cannot be sure that there is no onboard module 4, the bug, in any part of the disassembled TCB.

4. Since the activation of terminal 2 of cellular mobile communication is extremely rare and at times unknown to anyone other than the vehicle user, the time of the attack is very low. Even using an interference maker at the initial stage of the hijacking, the attacker will then be forced to turn it off so as not to unmask himself. Accordingly, it will again be possible to contact the TCB board.

Based on the foregoing, the proposed technical solution can be classified as creating a new additional line of protection for vehicles against unauthorized use. This line is triggered even when other lines of defense are overcome and the hijackers are confident in their success.

The TCB can be disassembled, put up for sale, held by the new owner - the hope of finding the TCB, or its individual parts, and returning it to its rightful owner - is preserved.

This solution is of particular interest to insurance companies, as it gives them a chance to significantly reduce the amount of cash compensation paid to the owner of the insured vehicle in the event of theft of its vehicle.

Thus, the task is solved - the radio search technology for stolen (stolen) vehicles is proposed, effective even in cases where the hijackers physically and / or using electronic jamming managed to neutralize the security and anti-theft system of this vehicle and other radio search systems.

The technical result achieved consists in the use of a specialized LBS service for determining the location of a SIM card subscriber of a cellular mobile network relatively recently introduced by regional cellular mobile communication operators. The proposed implementation of the inventive method is simple and affordable for a wide range of TS users.

Thus, the proposed technical solution is new and useful and can be classified as an invention.
