Description

The computer vehicle security system belongs to the field of electronic and computer technology and is designed to protect against theft, for example, cars, aircraft, swimming vehicles and other mobile objects, as well as to prevent unauthorized owners from entering or attempting to damage or move a transport object.

Known electronic security systems are mainly designed to provide sound signals when trying to enter the passenger compartment, trunk, engine compartment of a car. An example of such a car burglar alarm is a widely used electronic-mechanical device, acting from door lock sensors mounted in the car door or mechanical pendulums that give signals to the sound device when trying to enter the car interior. Another car alarm with an electronic identification code key and remote on and off switching in the invisible infrared range was developed by the authors for the Pyrometer plant in Leningrad and has been manufactured by this plant since 1992 for several years and has been used by some car owners to date.

A car alarm with a radio alarm has been known since 1994, in a simplified version it was manufactured by industry and operates as follows - when an attempt is made to enter a vehicle’s interior, an alarm is triggered by mechanical sensors or beacons and an alarm at a frequency of 28 MHz is broadcast and received by the radio car owner to take measures to prevent theft. In an expanded version, this anti-theft alarm system is connected to the landline phone of the car owner with automatic transmission of an alarm signal and identification information about the car to the security services or traffic police inspection panel.

A collective burglar alarm to protect car parking from theft of individual vehicles was developed in 1996 and mass-produced for the needs of the population. It represents a set of simple security sensors operating in the range of 27-28 MHz with a limited range. When attempting to enter the interior of any particular car, security sensors are triggered. The alarm and parking number of the car are received at the control desk of the guard. The dispatch console kit includes a receiver tuned to 28 MHz. When an alarm arrives at the remote control, the car parking number is displayed. Taking into account the general situation and its capabilities, the guard takes appropriate measures.

Known American anti-theft system company “Logic”, consisting of a receiver-direction finder, and is installed on a police helicopter model “Robinson-44”. The receiver detects a transmitter that is covertly mounted in a vehicle. A direction finding receiver from a height of 300 m covers an area of up to 100-120 km. In the event of a car theft, the transmitter is automatically activated and allows you to detect and detect from the air a car, even placed in a metal container located at a depth of 3 floors. The percentage of detection of stolen cars is unusually high. The only and most significant drawback of this system for detecting stolen cars is that it is very expensive not only in manufacturing but also in operation, like the police helicopter itself. The detection system on board the helicopter consists of an infravisor, a panoramic video camera and decimeter range radio stations and many other equipment, designed to search for the most expensive car brands. We need a police helicopter constantly barring in the air with a direction finding specialist on board.

Other electronic anti-theft systems are known, but they are built on the same principles and work in a similar way.

Known security alarms to protect vehicles from theft have common disadvantages:

- focused on the issuance of an alarm in an individual radio channel or raising a sound alarm when you try to enter the car interior and are easily neutralized by hijackers;

- with a limited set of protective functions, each individual electronic alarm device is quite expensive to manufacture and has relatively low reliability due to the low degree of integration of the element base;

- Each individual alarm device is easily detected by power wires and does not have a reliable degree of protection against mechanical, thermal and other damage, as well as from powerful electromagnetic fields and radiation.

All these shortcomings make the alarm devices easily vulnerable and ineffective means of protection against highly skilled hijackers equipped with scanning devices for opening individual identification codes.

The closest prototype is the Navigator vehicle tracking system. The purpose of this system is to provide for tracking the position of the vehicle in space during its movement, and also to provide an adequate level of protection for the vehicle from theft and attack on the driver. A car or other vehicle is equipped with a location control unit operating in three main modes of navigation tracking:

- “escort” - the main mode of vehicle location control, position information: vehicle coordinates and speed, arrives at the control post with a frequency of once every 15 s;

- “parking” - the mode used when the vehicle is parked for a long period of time, it allows you to instantly activate the special mode for transmitting data about the vehicle (every 15 seconds) in the event of unauthorized entry into the vehicle and / or moving the vehicle without permission of the owner;

- “alarm” - a special operating mode of the “Navigator” system, which provides continuous information support of the vehicle with the display of its topographic coordinates on an electronic map of the area (security console) and its speed in real time in case of theft. Although this system has several advantages: it allows you to continuously monitor the current location and speed of the vehicle and display it on an electronic digital road map of the area in the central control tower, as well as control deviations from a given route of movement, followed by continuous electronic tracking of the vehicle. The system allows you to enable the alarm when you try to enter, theft, robbery, loss of communication, system hardware malfunction. In this mode, “black box” reporting is generated from 1 to 30 days, containing information about changes in vehicle tracking modes, fixing the course of the emergency right up to its localization or elimination, and monitoring of commands and actions of the client and dispatcher.

The system used contains a number of disadvantages that weaken the advantages of this system. So, the vehicle or car’s location control unit is located in an accessible place for incapacitation, is visually easily detected and can be disconnected from the on-board power supply. The unit has a strict functioning program that does not take into account the specific situation of attempts to penetrate the vehicle and the condition of the units at the time of theft.

The specified system was developed for special escort vehicles, and its reliability in operation is closely related to the presence of special security services, coordinated routes for the movement of motorcades and numerous surroundings. In other words, the system is not designed for the mass motorist, which makes this system selected and focused only on the quick response service, consumer protection services, specialized mobile technical service and special emergency medical care and excludes its widespread use in everyday life of ordinary citizens. In addition, given the purpose of the Navigator system, there are no bibliographic sources of information in the open press. The navigation system Navigator was designed by a state institution without taking into account economic factors, since its wide commercial use was not expected.

The present invention is a computer system, which includes: a module located in a metal protective shell with a “transparency window”, which allows for the communication of the internal antennas of the module with external radio receivers and transmitters both inside and outside the car, and the module includes computer programmable microchip, satellite position unit with antenna, a set of radio receivers and transmitting devices for communication with transmitting equipment of navigation satellites, from a local cell howling or satellite communication systems, the state sensors of vehicle components located on various vehicle components, a microphone and a video camera, locking actuators, consisting of a receiving part, a relay circuit and mechanical, hydro or electric drives on various vehicle components, includes beacons having autonomous and / or powered by the on-board system of the car, and the beacons are located in various hard-to-reach parts of the car, owner ID, contactless charger, device fixed for the recharging period and fixed in the zone where the module is located, a sensor of destructive effects on the vehicle, identifiers of the serial number of the unit.

An internal computer system for guarding vehicles, for example, for a car works as follows: at the factory, a standard program of “behavior” is entered into the microchip memory — the responses of module 1 to all internal ones (from the state sensors of the vehicle units 10 and the electronic identifier 11, microphone -amplifier 13 and external signals - events: positional information from the satellite, requests from the local security system dispatcher or from the radio request of the car owner.

The module begins to function from the moment of installation on the object of protection, the connection of the internal power source 9 and the receipt of the encrypted code at the beginning of operation. From this moment, the computer security system is in standby mode. Under the normal “owner – vehicle” interaction procedure, the vehicle’s internal computer security system remains in a calm state, cyclically monitoring all internal and external influences using the state sensors of vehicle units 10 in the “black box” mode, recording information from the satellite position unit 5 and sensors of the state of the units of the vehicle 10, the electronic identifier block 11, requests via cellular communication about the location of the object, the condition of its serviceability, etc. The internal computer vehicle security system is activated, switching to the next mode of operation when attempts are made to unauthorized access (without the car owner’s identification code arriving in the electronic ID block 11 in the passenger compartment, trunk or in the engine compartment of the car, when trying to move or steal the car, when a signal is received alarms from electronic identifier 11, starting the engine with the ignition key turned off, opening doors, etc. The moment and air mode are set by algori by the adaptive program of the computer programmable microchip 4, taking into account the current general situation (the state of the sensors of the state of the vehicle’s 10 units, commands received from the electronic identifier 11 by the special command of the vehicle’s owner “Capture” or upon request from special equipment of the local security system dispatcher, or operation of a special protection sensor 18 in the event of an accident or disaster (emergency SOS beacon mode), taking into account all the priorities laid down in the adaptive “behavior” program. When intruders enter the cabin, a hidden video camera is turned on, the image and all acoustic signals are broadcast or recorded in the “black box” 20 of computer module 1. At the right time, the adaptive program includes one of the beacons 12 to distract the attention of hijackers, thereby masking the work the main transmitter, creating conditions for additional direction finding of the guarded transport facility with the equipment of the local security system and gaining time for organizing and intercepting vehicles nogo funds. When the hijackers turn off one of the beacons after some time, the adaptive program turns on the next beacon.

The emergency SOS beacon is turned on both by a person and by triggering the protection sensors 18, tuned to a certain value, which destroys the structure of the vehicle, overload. The SOS beacon is also activated by the covert “Attack” signal provided by the vehicle owner.

The identifiers of the unit number 19 mounted in the aggregates respond to a specific excitation frequency, and provide encrypted information about their belonging to a particular vehicle. The identifier is triggered when the unit is irradiated from an external scanner, which is pumped by the irradiation energy received by the antenna of the identifier 23 power supply. The identifier 19 is set when the unit is manufactured in a place inaccessible to visual detection.

The internal computer system for protecting vehicles, such as cars, from theft and other unauthorized actions against the interests of the car owner, requires special programs that allow you to change the “behavior” of the module depending on the current criminal situation, diagnose the state of the car or other vehicle systems. The ability to quickly change codes, passwords and an information encryption system eliminates the interception of this information by other third parties, which increases the security of the protected object and minimizes the chance of theft. The adaptive program’s unpredictable behavior for hijackers in the process of counteracting them to hijackers, turning on or off various units or electronic units that ensure engine operation, allows you to gain time and enable security services to prevent hijacking. At the same time, the computer vehicle security system provides the citizen with quick medical or technical assistance at the scene of a traffic accident, automatically sending calls to the duty posts of the corresponding operational services with information about the scene of the accident and the vehicle in distress.

The internal computer system for guarding vehicles is technologically advanced, for example, for a car, it is built from independent blocks and elements of both domestic and foreign production, according to standard interfaces adopted for personal computers, it can be configured depending on the requests of the consumer of services.
