Description

 The invention relates to alarm systems and can be used to monitor the condition and movement of vehicles, to protect stationary and moving objects, control traffic flows, as well as environmental monitoring.

 A known monitoring system, information service and protection of vehicles from unauthorized exposure (patent RU N 2155684, B 60 R 25/00, G 08 B 25/10, G 08 G 1/123, 04/05/2000) containing a telephone communication network and data transmission connected to a paging communication network, which includes an operator data transmission unit and subscriber receivers installed on vehicles, configured to activate immobilizers and with the ability to start beacon-type transmitters when receiving over a paging communication network go and beacon codes, respectively, as well as stationary transceivers geographically distributed on the road network, configured to receive alarms from the beacon type transmitter when its carrier enters the coverage area of this stationary transceiver and with the possibility of transmitting messages, at least to one of the base stations associated with the information center, which contains serially connected reception unit and primary processing unit, the outputs of which are accessed, respectively, to the registration unit and the display unit, while the stationary transceivers are configured to direction finding beacon type transmitters and measure the power of the signals received from them, and the information center contains a block for receiving and processing messages from external sources, a block for transmitting information messages, a block secondary processing connected to the outputs of the primary processing unit, the registration unit, the display unit and the unit for receiving and processing messages from external sources and made with the ability to determine the coordinates of vehicles from the aggregate data on the location of stationary transceivers that received alarms from the beacon type transmitters whose power exceeds a predetermined level, and measured power values of the received signals and bearings on them, as well as the ability to determine and account for the number of inclusions of the beacon transmitter type for carrying out financial calculations with the owner, the block for transmitting information messages through the voice messenger it is accessible to a geographically distributed network of centers for operational response, while vehicle owners are provided with transponder cards on which, in certain fields, they are protected with a special one-time coating, for example, paint, secret codes: blocking, beacon and settlement, which become visually accessible when the protective coating is removed, and in the digital memory of the transponder card an identification code is fixed, on each vehicle in the immobilizer control unit an ID code remote reading unit has been installed, which is part of the immobilizer control unit, as well as a manual input unit for unlocking code and associated outputs of the immobilizer control unit associated with the corresponding input of the immobilizer control unit - an operating mode indicator.

 The disadvantage of the above system is the low accuracy of determining the coordinates of controlled moving objects, significantly limiting the practical application of the system and forcing in some cases, for example, when searching and intercepting stolen vehicles, to use additional direction finding devices installed in conjunction with ground repeaters and / or on board search vehicles means (patrol cars).

 This drawback is eliminated in safety, control and navigation systems using the equipment of satellite radio navigation systems (GPS): American - NAVSTAR and / or Russian GLONASS.

 Thus, a safety, control and navigation system for automobiles is known, comprising a memory device for storing roadmaps in digital form, a device for inputting a destination, a device for generating digital speed and acceleration signals for indicating an emergency situation, and an antenna for receiving GPS satellite signals and signals carrying information about the transport stream and the transmission of alarms (US patent N 5504482, G 08 G 1/123, 04/02/1996). Received signals are converted to digital form. The processing device determines the current location of the car based on GPS signals and signals carrying speed and acceleration information, determines the first route between the current location and destination, and the second route at a high traffic density on the first route, transmits alarms encoded based on the current location if the acceleration of the car goes beyond the set limits, and controls the car by electronic means.

 The work of the known system is limited to the navigation of a mobile object, while the system does not allow highly accurate determination of coordinates in a differential mode, it does not provide sound support for the navigation situation, monitoring the health of the system’s technical facilities, and collecting and storing information about the consumer’s travel route.

 Known navigation device for a vehicle containing a detector of the coordinates of the current position of a car or other vehicle (Japanese application N 5059431, G 09 V 29/10). In accordance with the coordinates from the detector, the indicator of the current position of the car and the roadmap of a certain area are simultaneously displayed on the screen of the indicator unit. The device contains: a memory in which graphic information is stored for indicating a map of a given region, the coordinates of several special points within this region, and information about routes connecting these points with several target points of the region; a circuit for controlling the output of a district map display, acting on the basis of information read from memory; command scheme for selecting one of several target points; a scheme that, after selecting one of the target points, based on the relationship between the coordinates of the current position of the car and the coordinates of the special points stored in the memory, determines a special point located near the current position and determines the route connecting the nearest special point with the target point based on the stored route information ; a circuit controlling the display on the screen of the indicator block of the route set by the previous circuit.

 The device does not allow, however, to monitor the environment and search for stolen vehicles. There is no dispatch center, which would reflect the location of objects and their condition.

 These disadvantages are eliminated in the invention presented by patent RU N 2122239, G 08 B 25/10, 11/20/1998, selected as a prototype. The security, navigation and monitoring system presented in it contains consumer equipment including an autonomous power supply unit and a receiver of a high-precision radio navigation system (for example, GPS system) with an antenna, a transceiver with an antenna, a group of security sensors, and an on-board computer containing a processor designed to process signals from the navigation receiver and security sensors and generate information signals for transmission over the air, the interface connected to the processor, navigation the receiver and a group of security sensors, at least one dispatch center, made with the possibility of differential correction of coordinates of controlled objects and connected through the antenna of the transceiver via a radio channel with consumer equipment, an audio system and a manual data input unit (keyboard) connected to the on-board computer interface, and a modem connected to an autonomous power supply unit, which is connected to an interface and a transceiver, a video monitoring camera and a television monitor, the input of which is connected to one m from the outputs of the video monitoring camera, while the on-board computer contains a storage device connected to the interface, an analog-to-digital video signal converter, the input of which is connected to the second output of the video monitoring camera, and the output to one of the interface inputs, and two digital-to-analog converters, the inputs of which are connected with the corresponding outputs of the interface, and the outputs, respectively, with the audio system and with the second input of the television monitor.

However, this technical solution is also not free from disadvantages, the main of which are:
- the absence in it of technical means of counteracting unauthorized influence on an object, for example, means of counteracting theft or theft of a car;
- the impossibility of the system recognizing the owner of the object as "friend or foe" and blocking the movement of the object in case of unauthorized penetration of an attacker into it.

 The unique multifunctional capabilities of the prototype system are provided largely due to the variety and high technical parameters of the consumer's on-board equipment. Accordingly, the cost of this equipment is high. Therefore, the above disadvantages are very significant and significantly limit the scope of its practical application.

 The present invention is aimed at eliminating these disadvantages while maintaining all the advantages associated with the versatility of the prototype system.

 Namely, the object of the invention is to increase the effectiveness of countering unauthorized actions on an object, penetration of an attacker into it and further attempts to use this object, for example, hijacking or theft.

 The problem is solved due to the fact that in the well-known security, navigation and monitoring system, containing consumer equipment, including a navigation receiver with an antenna, operating on the signals of satellite radio navigation systems and providing geodetic accuracy in determining the coordinates of objects, a transceiver with an antenna that implements cellular, trunking or satellite radio communication with a control center made with the possibility of differential correction of coordinates of controlled objects and their location and identification parameters on an electronic terrain map, an on-board computer with an interface, a processor, a storage device, an analog-to-digital converter and two digital-to-analog converters, the inputs of which are connected to the corresponding outputs of the interface, and the outputs, respectively, to the input of the audio system and to the first the input of the television monitor, the second input of which is connected to the first output of the video camera, the second output of which is connected through an analog-to-digital converter with the corresponding input of the interface, one of the outputs of which is connected to the control input of the navigation receiver, the output of which is connected to one of the inputs of the interface, as well as a set of security sensors connected to the corresponding input of the interface and made in the form of sensors of unauthorized influence on the protected object, sensors for monitoring environmental parameters environment and sensors of the technical parameters of the protected facility, a modem that implements cellular data exchange protocols, depending on the type of radio used, trunking or satellite communications networks, the first input of which is connected to one of the outputs of the interface, and the first output is connected to the input of the transceiver, the second input of the modem is connected to the output of the transceiver, and the second output is connected to the corresponding input of the interface, as well as the manual data input unit, output which is connected to the corresponding input of the interface, one of the outputs of which is connected to the processor, and the other output - to the storage device, while the outputs of the processor and storage device are connected to the corresponding inputs of the interface, - as part of the app Customer’s credentials introduced an additional subscriber receiver, which is part of the public paging communication network, a transponder card, a remote reading unit with an antenna, which is capable of reading an identification code recorded in the digital memory of the transponder card, on the surface of which are coated with a special one-time coating, for example paint, secret codes that become visually accessible only when the protective coating is erased, as well as an indicator security sensors operating mode, the first input of which is connected to the first output of the remote reading unit, and the blocking unit of the functional organs of the protected object, while the interface included in the on-board computer is made with two additional inputs and two additional outputs, the first additional interface output is connected to the input node blocking the functional organs of the protected object, the second additional output of the interface is connected to the second input of the indicator of the operating mode of security sensors c, the first additional input of the interface is connected to the second output of the remote reading unit, and the second additional input is connected to the output of the subscriber receiver, the input of which is connected by radio to the operator data transmission unit, which is part of the paging public communication network.

 The drawing shows a functional diagram of the proposed security system, navigation and monitoring of vehicles.

 The diagram shows: operator unit 1 for data transmission, paging communication network 2, transponder card (TC) 3, subscriber receiver 4, interface 5, on-board computer 6, node 7 for blocking the functional organs of the protected object, processor 8, storage device 9, transceiver 10 , modem 11, navigation receiver 12, dispatch center 13, manual data input unit 14, analog-to-digital converter 15, digital-to-analog converters 16, security sensors 17, video surveillance camera 18, television monitor 19, audio system 20, mode indicator 21 Ota alarm sensors, remote reading unit 22.

 The paging communication network 2 includes a subscriber receiver 4, which is part of the consumer equipment, and an operator data transmission unit 1 connected to it by radio, which the subscriber can access, for example, via a public telephone network. The output of the subscriber receiver 4 is connected to an additional input of the interface 5 of the on-board computer 6, which further comprises a processor 8, a storage device 9, an analog-to-digital converter 15, and two digital-to-analog converters 16 combined into a single structural unit. The interface 5 provides two-way interaction with the transceiver 10 (via modem 11) and the navigation receiver 12 of the GPS system. A block 14 of manual data input is connected to one of the inputs of the interface 5, for which, for example, a keyboard can be used. The transceiver 10 using the antenna provides communication over the radio network with the dispatch center 13. As in the prototype, the invention can use cellular, trunking or satellite communications.

 Dispatch center 13 is designed to collect, process, accumulate and display information from geographically distributed sources, followed by the development of information messages and control teams. It has a standard configuration, described, for example, in the study guide V.A. Minaeva, V.V. Umerenkova "Space navigation systems in the activities of operational services", Orel, 1999 (p. 81).

 The consumer equipment also includes a node 7 for blocking the functional organs of the guarded object, security sensors 17 of various types, including those used to assess the state of the environment and technical parameters of the object, a video monitoring camera 18, a television monitor 19, an audio system 20, an indicator 21 of the operation mode of the security sensors and a unit 22 for remote reading of data used for reading from the TC 3. All of the above blocks are connected to the on-board computer 6 and are controlled by it in accordance with the specified operating mode early sensors, the messages of the paging communication network 2, arriving at the subscriber receiver 4, and the messages from the dispatch center, arriving at the transceiver 10 via one of the aforementioned radio networks.

 The functional diagram described above does not contain any blocks whose implementation would require additional detail and a separate description. However, a specific type of implementation is not essential for this invention.

 So, for example, as a video camera 18, a wide-angle, miniature internal surveillance camera with a Pin-hole type lens can be used. Industrial cameras of the following type can also be used: front (rear) review of the external space around the object of control, a circular view of the visible or infrared wavelength ranges on a rotary device or a television camera on a gyro platform for installation on mobile environmental monitoring equipment, etc.

 From the point of view of the problem solved by the present invention, a more detailed description of the apparatus presented in the claims and in the drawing is not required.

 The proposed system of safety, navigation and monitoring of vehicles works as follows.

 When arming an object or testing subscriber equipment for operability or when an unauthorized exposure to an object is detected, for example, a car theft attempt, a system subscriber (owner of the object) reports this by telephone to the operator unit 1 for transmitting data, which is part of the paging communication network 2. So, when an object is armed, the data transfer unit 1 is notified, for example, by phone of the pager address (individual number) and a blocking code, and during a test for working obnost equipment or alarm upon tampering facility operator to further communicate the special secret codes. The subscriber recognizes them after erasing (for example, with a coin edge) the protective coating from the corresponding fields on the surface of shopping mall 3. The operator receives the indicated telephone message and sends the corresponding code message to the specified address. At the object located in the reception area of the paging communication network 2, these encoded signals are received by the subscriber receiver 4 and sent to them through the interface 5 to the processor 8 of the on-board computer 6, connected to the block 7 of the functional organs of the protected object.

 The blocking code is sent from the interface 5 to the processor 8 of the on-board computer 6, where it is compared with the internal blocking code previously selected in the memory 9 and selected from it via the interface 5. When these codes coincide, the processor 8 generates a command to block the functional organs of the protected object, for example, a car engine. This command through the interface 5 enters the node 7 blocking the functional organs of the protected object. For example, if the object of protection is a car, then the immobilizer control unit, HOOK-UP relays, etc., can act as a node 7.

 In this case, to block the engine of the car during its theft, the owner does not need to know the location of the car. A prerequisite is only to find the car in the coverage area of the external paging network 2.

 At the same time, when the subscriber receiver 4 receives a special secret code and transmits it through the interface 5 to the processor 8, the latter generates and transmits sequentially through the interface 5 and the modem 11 the start command of the transceiver 10, which transmits alarm messages to the surrounding space containing individual identification codes signs of the protected object, for example, codes of the state number, make and color of a car that has been subjected to unauthorized influence by an attacker.

 The type of radio data network is not essential for the present invention. So, for example, in the aforementioned patent RU N 2155684 for transmitting alarm messages from a guarded object to a dispatch (information) center, a microcellular data transmission network specially formed on the ground using low-power repeaters is used. In other applications of the system in question, a GSM cellular network, a trunking network, or satellite communications system can be used for this purpose. The type of communication radio network used determines the corresponding type of data exchange protocol implemented in the transceiver 10.

 If the object of protection is a moving object, such as a car, then when solving a number of functional tasks, for example, in the case of theft (theft), the task arises of determining with high accuracy the coordinates and displaying the location of the car (symbol) on an electronic map of the city, accompanied by an explanatory text information.

 The coordinates of an object are determined with high accuracy by the traditional method in this invention — by introducing a navigation receiver 12 into the consumer’s on-board equipment for receiving signals from the NAVSTAR and / or GLONASS satellite global system (GPS). The navigation receiver 12 receives through its antenna the signals of the above systems, processes them, and transmits the processing results sequentially through the interface 5 and modem 11 to the transmitter of the transceiver 10. This data, together with the codes for the identification features of the object (see above), are transmitted through the antenna of the transceiver 10 and after passing through the radio network they arrive at the control center 13.

 A specific embodiment of the technical implementation of the dispatch center 13 is also not an essential feature for this invention. In any case, it includes a fairly efficient computer equipped with a system for displaying graphic and semantic information against the background of an electronic city map (GIS). As a GIS, various software systems can be used, for example, based on well-known commercial products Arcinfo, Maplnfo, etc. To obtain the highest possible (geodetic) accuracy of measurements in the computer of the control center 13, differential correction of the coordinates of the objects can be provided. In this case, the navigation equipment of the NAVSTAR and / or GLONASS satellite systems, similar to the navigation receiver 12, is introduced into the equipment of the center, and the corresponding algorithmic correction procedure is used in the computer software of the control center 13. However, neither the presence of the differential correction mode, nor the method of its specific implementation in the dispatch center are significant from the point of view of the problem solved by the present invention.

 An alarm signal about unauthorized exposure to a protected object can be triggered automatically. The choice of this mode is carried out by the subscriber by typing the appropriate command in block 14 manual data entry. This command then comes through interface 5 to processor 8, which is part of the on-board computer 6, where, for example, a command is generated to connect power to the previously de-energized analog-to-digital converter 15 and digital-to-analog converters 16, which are part of the on-board computer 6, and also to all or part of the security sensors 17, the video camera 18, the television monitor 19, the audio system 20.

 The signal about arming the object is generated by the processor 8 and sequentially through the interface 5, modem 11 and transceiver 10 is sent over the air to the dispatch center 13.

 The neutralization of the operation of any security sensors 17 is provided by the dialing by the subscriber of the system (the owner of the protected object) of the corresponding code in block 14 of the manual data input. If the dialed code matches the code stored in the storage device 9, the processor 8 gives a signal to disarm this object (or to disable any security sensors), which is sequentially transmitted through the interface 5, modem 11, transceiver 10 and the radio network to the control room center 13 for presentation to the operator.

 In case of unauthorized entry into a guarded moving object, for example, into a car accompanied by the operation of any security sensors 17, at the command of processor 8, an activation signal is transmitted via interface 5 to navigation receiver 12. The latter starts to generate messages that carry information about the vehicle’s location, which are transmitted via the interface 5 are received for processing by the processor 8. At the same time, the video monitoring camera 18 starts transmitting image frames of the internal situation at the protected object, which e may comprise, for example, intruder image. This signal is converted by an analog-to-digital converter 15 into a digital code transmitted via an interface 5 to a processor 8 for compression and preparation of digital image frames for transmission over a radio network. Then, with a specified period, consistent with the speed of information transmission over the radio network, information messages containing navigation information and image frames are transmitted via interface 5, modem 11, transceiver 10 over the radio network to the control center 13. The operator of this center can monitor and analyze this simultaneously data on the location of the protected object, data on the direction and speed of its movement on the road network, data on the owner, data on the technical passport on the protected object, fra Image elements of the internal situation on it, for example, the image of the hijacker and other important data for making operational decisions.

 The specific technical implementation of the video camera, the choice of its installation location and monitoring parameters are not the subject of the present invention. An essential feature for him is the technical implementation of the function of identifying the owner according to the principle of "friend or foe". This function is realized by introducing into the composition of the consumer equipment a remote reading unit 22 connected via an antenna with a TC 3 located at the owner of the protected object. This technical solution is widely used in anti-theft and security automobile systems such as Black Bug, Guard, Reef, which are mass-produced by the applicant enterprise. In combination with the other aforementioned features, it gives rise to a new quality - the effectiveness of a comprehensive response to unauthorized exposure to a protected object, the penetration of an attacker into it and subsequent attempts to use this object, for example, hijacking of a vehicle, sharply increases. At the same time, all the advantages associated with the multifunctionality and high accuracy of determining the coordinates of moving objects inherent in the prototype system are retained.

 This is achieved due to the fact that the functional organs of the guarded object, for example, the engine or the vehicle’s ignition system, are released and enter the operational state only when the TC 3 is placed in a designated area relative to the antenna of the remote reading unit 22. This automatically reads the identification code fixed in the digital memory of the TC 3 and compares it with the unlocking code recorded in the storage device 9 of the on-board computer 6.

 So, for example, to protect the car from theft, the antenna of the remote reading unit 22 is placed in the back of the driver's seat. If the TC 3 is in the pocket of the driver’s jacket, then when it takes its place in the car, the identification code stored in the digital memory of the TC 3 is automatically read, which is then transmitted via interface 5 to processor 8. If this code matches the unlock code located in the memory device 9 of the on-board computer 6 and selected from it via the interface 5, the processor 8 generates a command to unlock the functional organs of the car and the car owner gets the opportunity to use in normal mode.

 In the absence of the subject penetrating the car, the TC 3, the node 7 continues to block the functional organs of the car or, if in the initial state they were unlocked, carries out their blocking after a certain period of time by issuing a sequence of commands for smoothly shutting down the engine.

 In the simplest case, the TC 3 can be an element with a variable (changing in accordance with the identification code) load for the electromagnetic signal generator, which is part of the remote reading unit 22.

 When the unlocking code is changed by the owner of the protected object, the TC 3 is replaced with another card and the corresponding reprogramming of the remote reading unit 22 is carried out.

 All operating modes of the security sensors 17 are displayed by the indicator 21 of the operating mode of the security sensors, which in different modes is lit with a steady or flashing light, or alternately both. The indicator 21 is controlled by the processor 8 through the interface 5 of the on-board computer 6.

 Commands and messages received by the subscriber receiver 4 via the paging communication network 2 can be voiced by the audio system 20 and displayed on the TV monitor 19 after they are sent via interface 5 and converted to an analog signal in digital-to-analog converters 16.

 Thus, the combination of the features and distinctive features of the claimed system common with the prototype system generates a new quality - significantly higher efficiency in countering unauthorized exposure to the protected object, the penetration of an attacker into it and attempts to use the protected object for their own purposes.

 At the same time, all other functionalities inherent in the prototype system are stored and can be used for their intended purpose: high-precision navigation of the object, including using the differential coordinate correction mode, video surveillance, remote testing of equipment, environmental monitoring and the internal state of the object.

 Moreover, all the features presented in the application are in functional unity, contributing to the solution of the task.
