Description

The group of inventions relates to the field of protection of mobile objects with a closed cabin, equipped with doors, from unauthorized entry and access to their management and use.

It is known that the most vulnerable places for mechanical hacking are mechanical control nodes associated with the use of a mechanical key.

At present, vehicle manufacturers are solving the problem of protection against theft in two directions:

- the installation of additional servos that block the mechanical drives of external mechanical locks remotely via a radio channel;

- embedding in the key for its identification of an electronic identifier, using, as a rule, the method of exchange with transformer communication.

There is, for example, a vehicle security method implemented by the Alligator LX 440 alarm system, which provides for the transmission of an identification code remotely via radio channels using remote control transmitters (Car alarm from A to Z. - St. Petersburg: Nauka i Tekhnika, 2002, p.14).

Common signs with the claimed method are the following - identification of the code carrier, locking the doors and arming by locking the door locks, providing access to the cabin by disarming and unlocking the doors.

In the known method, the most common method for identifying an access code using a radio channel is implemented today. The transmitter of the key fob forms a digital packet that modulates the high-frequency radio signal transmitted to the security unit.

However, the known method provides insufficient stability of the vehicle to unauthorized actions aimed at breaking it and hijacking due to the following disadvantages:

- dependence of the code transmitter on the power source;

- low noise immunity due to the possibility of using electromagnetic interference generation devices by hijackers of vehicles, which reduces the level of protection of the object of protection;

- the identification code package is available for reception not only to the security unit, but also to the exchange monitoring equipment (scanners), and the presence of scanners from the hijackers also reduces the reliability of the protection;

- the presence of a mechanical component for locking and unlocking (door locks and ignition switch).

The method of vehicle protection implemented by the CarMan anti-theft system of modification CM 1990 (Andrianov V.I., Sokolov A.V. Automotive security systems. Reference manual. - SPb .: BHV-Saint Petersburg; Arlit, 2000, p. 19-23). The prototype method provides for the following operations:

1. Access to the salon through a standard key.

2. Disarming by conducting for 8 seconds the contact identification of the electronic key code by touching the electronic key of the contact area of the code reader located in the passenger compartment.

3. Carrying out engine start by using the standard key.

4. Turning off the engine by using the standard key.

5. Arming with an electronic key by touching the contact area of the code reader located in the vehicle interior.

6. Locking the doors with a standard key for 8 seconds from the moment of arming.

The main common feature of the prototype method with the claimed method is the use in it for disarming and arming the reception of contact identification code, carried out by touching the electronic key of the contact area of the code reader. Other common signs are locking and unlocking door locks, engine blocking and unlocking the engine, turning the engine on and off.

The prototype method does not guarantee the stability of the vehicle against unauthorized actions aimed at hacking and hijacking a vehicle, as a result of the following:

1. It is possible to enter the car interior due to the presence of mechanical locking components (door lock, trunk lock, traction inside doors from locks to actuators).

2. It is possible to start the engine due to the presence of a mechanical component (ignition switch), the control function "ignition on", "engine start".

3. It is impossible to quickly change the key by the owner of the car, since in the event of the loss of the electronic key, it is necessary to reprogram the code in the manufacturer of the electronic unit.

Known anti-theft system Alligator LX 440 (car alarms from A to Z. - SPb .: Science and technology, 2002, p.16), containing a central unit transmitting a key fob, an antenna for receiving a radio signal, security zone sensors, a central locking and unlocking control unit doors, audible warning device, engine starter relay.

Common features of a similar device with the claimed device are a central unit, a centralized locking and unlocking control unit for doors, security zone sensors and a sound siren (siren).

An analog device does not ensure the vehicle’s resistance to unauthorized actions aimed at hacking and hijacking, due to the following factors:

- dependence of the code transmitter on the power source;

- low noise immunity;

- the availability of the identification code package to the exchange monitoring equipment (scanners);

- the presence of mechanical components for locking and unlocking (door locks and ignition lock).

The CarMan anti-theft system of the CM 1990 modification (Andrianov V.I., Sokolov A.V. Automotive security systems. Reference manual. - SPb .: BHV-Saint Petersburg; Arlit, 2000, p. 19-23), which has common signs with the claimed device: central unit, immobilization unit, code reader, sensors of security zones.

The prototype device does not provide sufficient stability of the vehicle against unauthorized actions aimed at breaking it and hijacking due to the lack of an additional code reader, power control unit, engine start recognition unit and attempted movement, as well as due to imperfection of the central unit. The central unit in the prototype device does not allow controlling the electromechanical drive for locking / unlocking door locks and the vehicle’s power supply system, but only allows the engine to be immobilized and signal an unauthorized entry into the cabin and an attempt to supply voltage to the ignition system circuits.

The technical result of the invention is to increase the stability of the vehicle to unauthorized actions aimed at hacking and hijacking, by providing multi-level protection.

A high level of protection and reliability of the claimed invention is:

- firstly, to prevent the possibility of using a mechanical hacking tool (master key) due to the rejection of the mechanical unlocking component located outside the object (replacing it during installation of the system on the code reader) and the rejection of the internal mechanical component - the ignition switch (disconnecting electrical circuits from the contact group of the ignition switch and connecting them to the power control unit);

- secondly, through the use of a closed channel for obtaining an access code;

- thirdly, by providing the ability to quickly change the access code to a mobile object when the access code carrier is lost through the use of privileged access technology.

The technical result is achieved in that in a method of guarding a vehicle, including disarming and arming with an electronic key by contacting the electronic key code by touching the contact area of the code reader, locking and unlocking door locks, turning the engine on and off, locking the engine and unlocking the engine, according to the invention, locking and unlocking door locks, turning the power system on and off I carry out using one of the many electronic keys, one of which has the status of "Master", disarming is carried out in two stages, and the first stage of disarming and arming is carried out outside the vehicle by contact identification of the electronic key code by touching the contact area of the code reader located on the outside of the vehicle, and unlocking the door locks is carried out simultaneously with the first stage of disarming And removal of the engine block and the power supply switch is performed simultaneously with the second step of disarming carried out inside the passenger compartment, while blocking the door lock and engine lock off the power is performed concurrently with arming.

In the event of the loss of at least one of the many electronic keys, the codes of the set of electronic keys are changed using an electronic key with the status "Master". In this case, the change of codes and / or addition of codes of electronic keys is carried out by contact identification of the electronic key code with the status "Master" by holding it on one of the contact pads of the vehicle code readers (outside or inside).

The technical result is achieved by the fact that the vehicle security device comprising a central unit, an immobilization unit, a code reader, security zone sensors, a central locking and unlocking unit for doors, according to the invention further comprises a security code activation and disarming code reader, a power control unit , a recognition block for starting the engine and attempting to move, while the inputs of the central block are connected to the outputs of the sensors of the protected zones, the recognition block for and OSCAL engine attempts motion code reader and the contact group of engine start. The outputs of the central unit are connected to the inputs of the central locking and unlocking unit, immobilization unit, power control unit and alarm unit.

The claimed invention is aimed at eliminating the possibility of opening (unlocking the lock) of the doors of the cabin outside the object. Carrying out the operations of disarming and unlocking door locks, locking doors and arming with an electronic key by means of an electromechanical servo-drive allows you to remove the standard drives and associated mechanical locks.

The exclusion of mechanical door locks (trunk, tailgate) increases the mechanical security of the vehicle from entering the passenger compartment and its resistance to theft, since door locks are unblocked and access to the passenger compartment by breaking the passenger compartment glazing is a stopping factor, as this will trigger an alarm , as well as attract the attention of third parties, and in the cold season makes it difficult to drive.

Locking door locks with an electronic key allows the claimed method to carry out the arming operation outside the vehicle interior, that is, to carry it outside the vehicle, which allows the vehicle to be locked and unlocked only in this way, which increases resistance to theft and prevents access to property inside the cabin.

The technical result is achieved by intercepting the function of the ignition switch by the central unit of the claimed device. By generating control signals to the power control unit, the central unit turns on and off the on-board power supply of the vehicle, and also starts the vehicle power plant. In other words, the system takes on the function of the ignition switch, which automatically leads to the first stage of immobilization (power supply circuit of the engine management system and start).

In turn, the servos block or unlock the operation of the vehicle interior door locks under the control of the central locking and unlocking unit according to signals from the central unit.

The inventive device has the ability to quickly change information about the media access code (electronic keys) stored in the memory of the Central unit by using the media access code registered in the system as "Master", with which access to the erasing and programming of the key table is performed. The status of "Master" consists in the ability to bring the system into a state in which it is possible to record or erase from the non-volatile memory of the central unit information about the access code carriers, including the "Master". This function allows the owner of a key with an access code having the status "Master" to quickly erase or record information about an individual media code in the memory of the central unit within 10-30 seconds using a private channel for obtaining an access code.

It is known from the prior art to block the entrance doors of real estate objects using electronic locks using the contact identification method using an electronic key to control the door lock (Telesystems: Microelectronic projects. Leonid Ivanovich Ridiko, Viktor Petrovich Lapitsky. Electronic lock with keys iButton http: / /www.telesys.ru/projects/proj054/index.shtml).

In the claimed combination of signs, unlocking the car door locks with an electronic key allows not only to control the door lock, but at the same time remove the first security level (turn off the alarm) by the vehicle owner, and when locking door locks, simultaneously lock the engine, turn off the power and arming, i.e. controlling the onboard power supply, the engine and the immobilizer, which leads to the vehicle's resistance to unauthorized shared access.

In the claimed combination of features, the level of protection of the vehicle from unauthorized operation or theft is increased due to the emergence of new stopping factors, which together form the cumulative effect expressed in that the car security system operates in accordance with regular operations of unlocking / locking the car, starting the engine, providing high service level of operation of the vehicle, while excluding the situation when the vehicle may be engaged put into operation without the permission of the owner. After mounting the inventive device in the electrical equipment of the vehicle, it is always guarded if it is closed. To open the car, you must turn off the alarm by any of the set of keys recorded in the system. This indicates the high operational characteristics of the device and the high reliability of theft protection.

In the claimed combination of features, the contact identification of the electronic code carrier makes it possible to make the interior of the vehicle inaccessible, as well as things inside the cabin. In the case of equipping a vehicle with shock-resistant glazing (armor glass), the cabin automatically becomes impregnable without special equipment for opening the passenger compartment.

It is also known to use technologies for quickly changing the identification code carrier in the memory of the central unit, for example, when reprogramming a keyfob in well-known models of car alarms, for example, Alligator LX440 (Car alarms from A to Z. - SPb .: Nauka i Tekhnika, 2002, p.14, 16 )

In the known solution, it is possible to intercept the identification code by the scanner and transmit it to the vehicle security unit, without the knowledge of the owner. Thus, by turning off the alarm, theft of the vehicle becomes possible without attracting the attention of others.

In the claimed combination of features, code interception is excluded, and the contact identification of the electronic code carrier allows the algorithm to quickly erase and record electronic key codes, which makes it possible to reduce or expand the circle of users of the vehicle by the owner of the key, the code of which has the status "Master".

The inventive objects (method and device) provide self-protection of the vehicle. Moreover, the car not only prevents the hijackers from entering the cabin and counteracts their actions in all directions, but also performs new service functions that are not peculiar to it - the rapid change of electronic key codes without additional funds.

The inventive group of inventions suggests the possibility of corporate use of a mobile device by a group of users while maintaining a high level of protection, which corresponds to modern requirements for the operation of vehicles.

Thus, the analysis of the known solutions confirms that the influence of the signs coinciding with the distinctive ones is not known to increase the vehicle's resistance to actions aimed both at hacking and hijacking, as well as penetration with the aim of stealing property inside the vehicle’s interior, which proves the conformity of the claimed group of inventions the criterion of "inventive step".

The method is as follows:

1. Outside the vehicle, the first stage of disarming is carried out simultaneously with the unlocking of the door locks by conducting contact identification of the electronic key code by touching the electronic key (with any of the many electronic keys) of the contact area of the code reader located on the outside of the vehicle.

2. After providing access to the salon, open the door and go inside the cabin.

3. Inside the cabin, the second stage of disarming is performed with the simultaneous inclusion of the power supply system and unlocking the engine by touching the electronic key of the contact area of the code reader located in a place convenient for the driver of the vehicle.

4. The engine is started by closing the contact group (pressing the button or turning the key to start) starting the engine.

5. The engine is stopped and the power is turned off by closing the contact group of the engine start or by touching the electronic key of the contact pad of the second-stage code reader.

6. Leave the cabin and close the door.

7. The vehicle is armed at the same time as the door locks are locked and the engine is locked by means of contact identification of the electronic key code by touching the contact area of the code reader located on the outside of the vehicle.

8. In the event of the loss of one of the many electronic keys, contact identification of the electronic key code with the status of "Master" is carried out by holding it for 10 seconds on any contact area of the vehicle code reader.

9. If it is necessary to increase the number of persons using the vehicle, the electronic key code is contacted with the Master function by touching the contact area of the vehicle code reader located outside or inside the cabin to record new electronic key codes.

10. Using the "button to start the engine and turn off the power", enter the inventive device into the setting mode of service functions. The setting parameter is switched by conducting contact identification of the code of one of the many keys, and the setting is changed by closing the "contact group for starting the engine." In this case, the settings are displayed by turning on the ignition (visually - turning on the instrument panel), and the position number by alarms.

The invention is illustrated by drawings:

figure 1 presents a functional diagram of the inventive device; figure 2 is a flowchart of the procedure "Registration code" Master "key"; figure 3 is a block diagram of the algorithm of the security mode "Alarm is on"; figure 4 is a flowchart of the procedure "Waiting for confirmation of disarming"; figure 5 is a block diagram of the mode "Alarm is disabled"; figure 6 is a flowchart of the procedure "Arming". The flowcharts in Fig.2-6 describe the algorithm of the program recorded in the memory of the microcontroller of the Central unit 1.

The vehicle security device contains a central unit 1, an immobilization unit 2, a code reader of the second stage 3, sensors of protected zones 4 and 5 (the number of sensors is determined by the number of security zones), a central locking and unlocking unit for doors 6, a reader of the activation code for the security mode and the first security level 7, power control unit 8, engine start recognition unit and attempted movements 9 and alarm unit 10, engine start contact group 11.

In this case, the inputs of the central unit 1 are connected to the outputs of the sensors of the security zones 4 and 5 of the engine start recognition module and attempts to move 9 and the readers 3 and 7, and the outputs of the central unit 1 are connected to the inputs of the central locking and unlocking door 6, immobilization unit 2, power control unit 8 and an alarm unit 10. The contact group of the start button of the engine 11 is connected to one of the inputs of the central unit 1.

The central unit 1 can be made on the basis of a microcontroller (for example, AT90S2313 - Evstifeev A.V. Microcontrollers AVR of the Classic family of the ATMEL company. M: Publishing House Dodeka-XXI, 2002; PIC16C57 / 58 - Tavernier K. PIC- microcontrollers. Practice of application: the lane with fr. - M .: DMK Press, 2002) and discrete elements by way of one-sided printed installation. The electrical circuit of the device is simple in execution, while all the protection functions (overvoltage, reverse polarity, overload of the outputs) are fully respected.

The immobilization unit 2 can be made on the basis of a microcontroller (AT90S2343 - Evstifeev A.V. Microcontrollers AVR Classic family of the company "ATMEL" - M .: Publishing house "Dodeka-XXI", 2002) and a miniature relay (TQ2-5v, http: / /efo.ru/cgi-bin/go?84, received on September 3, 2004) containing a group of switching contacts. The immobilization unit 2 has compact dimensions for flush mounting.

Readers of codes 3 and 7 - standard metal mortise contact nodes made in the MicroCAN standard (http://dbserv.maximic.com/quick_view2.cfm?qv_pk=2974 the document is dated November 22, 1999, received May 10, 2004).

Sensors 4 - as a rule, any standard sensors of the vehicle or optional door limit switches, any sensors registering penetration into the cabin are combined according to the “mounting or” scheme and connected to the input of the central unit (Andrianov V.I., Sokolov A.V. Automotive security systems. Reference manual. - SPb .: BHV-Saint Petersburg; Arlit, 2000, p.11).

Sensors 5 - referred to in the text as an "external sensor", any sensor that registers a mechanical effect on the vehicle body. Usually a “shock sensor” or the first response level of a two-level “microwave sensor” is used (Andrianov V.I., Sokolov A.V. Automotive security systems. Reference manual. - St. Petersburg: BHV-Saint Petersburg; Arlit, 2000, p. 11-14).

Block centralized door locking 6 - can be performed on two relays of a closed type (SRD-S-112D, http://at.ur.ru/comp/relavs.shtml, the document is dated September 9, 2004, received September 17, 2004 .).

Power supply control unit 8 - can be made on the basis of closed-type electromechanical relays (SRD-S-112D, http://at.ur.ru/comp/relays.shtml, the document is dated September 9, 2004, received September 17, 2004 .) by means of printed wiring.

The recognition unit for starting the engine and attempting to move 9 - is a functional unit and is part of the central unit 1. For its operation, any periodic signal arriving synchronously with the engine speed is fed to the input of the central unit 1 (spark control signal, tachometer signal, electromagnetic valve control signal nozzles and so on).

The light and / or sound signaling unit 10 - may be made by connecting the output of the winding relay of the standard horn relay and / or the light signaling relay of the vehicle dimensions with the output of the central unit 1.

The engine start and stop button 11 is any normally open pair of contacts that is closed by any human action. You can use the ignition starter start contacts. The engine start signal will be sent in the usual way. Thus, turning the key in the ignition switch to “START” with the engine running will turn off the ignition.

The central unit 1 contains a microcontroller with a program recorded therein. The program is written in machine-oriented assembly language. The kernel of the program recognizes all sensory influences in real time, and also maintains a 1-Wire exchange protocol with iButton ™ keys (http://rs232.ru/docs/1wire/doc009.html, received on September 2, 2004). The presence of a real-time counter, working on interruptions from the hardware timer-counter, allows you to clearly track the time intervals of events. The presence of non-volatile data memory allows you to save the operating settings and the current mode of operation of the device in case of an unexpected shutdown of the power supply of the central unit 1. The program contains entry points into code blocks from which the program resumes depending on the value of the mode stored in non-volatile memory. After power is restored, the device resumes operation in the same mode as the power supply of the central unit 1.

For the exchange between the code carrier and the code reader, a single-wire bus using the 1-Wire protocol is used. The electronic key (carrier of the identification code) is the iButton ™ device (http://rs232.ru/docs/1wire/doc009. Html received September 2, 2004).

An improved algorithm for interrogating keys for code carriers makes the code selection method unsuitable for access to the system.

The hardware of the power control unit 8 functioning under the control of the central unit 1 completely replaces the ignition switch of the car as a functional unit. When installing the system, the larvae of the door (trunk) locks are removed and the contact group of the ignition switch is disconnected from the power switching circuits. The power switching circuits are connected to the terminals of the power control unit. This circumstance provides increased protection against mechanical burglary of the interior of modern cars in combination with security functions (engine locks, switching power supply and starter, alarm), as well as the absence of an open code exchange channel, the central unit 1 provides reliable protection of the car against unauthorized entry and movement on its own.

A functional feature of the central unit 1 is the ability to start the engine by a single closure of the contact group of the engine start or automatic restart mode of the engine after disarming. The central unit 1 itself controls the engine start using signals from the engine start recognition unit and the attempt to move 9, disconnecting the starter after starting the engine.

Another important feature of the claimed device is the ability to quickly destroy the key table (in case of loss of a working electronic key) and quickly program a new set of keys. This algorithm is supported using the main key with the status "Master". Other keys do not support the programming / erasing procedure. In the process of erasing the table of key codes, the key code with the status of "Master" is also destroyed, which allows you to change it. This circumstance excludes the possibility of car theft even by the installer of the system.

In the "alarm on" mode, the central unit 1 monitors the status of the following protected zones:

- The appearance of power in the on-board network

- Door closed sensors (hood, trunk)

- External sensor (shock sensor, motion sensor, volume sensor)

- An attempt to select a code.

When the engine warm-up function is activated in the armed mode, when the engine is started, the external sensor is disarmed. At the same time, the following are included in the protected areas:

- Engine speed; when the engine is stopped, the engine warm-up function is canceled

- Engine speed - when increasing above the set limits, an alarm is triggered and engine start is blocked

- Attempted movement, is recorded by the engine start recognition unit and the attempted movement 9.

The device operates in the following modes:

1. Register the "Master" key. In this mode, the central unit is located if there are no key identification codes in its non-volatile memory. The block enters this mode immediately after the key erase procedure. By touching the key to the reader 2, the first key is registered. The read key code is written to non-volatile memory, this key is assigned the status of "Master". Immediately after registering the first key, the central unit switches to security mode 2.

2. Armed. The inclusion of this security mode is carried out by conducting contact identification of the code of one of the many keys by touching the contact area of the reader 7 located outside the vehicle. When a disturbing factor occurs, the central unit 1 turns on the sound and / or light alarm or turns on the pager transmitter for 20-30 seconds. If zone violation continues, the alarm repeats. In the event of a prolonged lack of response to a car alarm, the violated guarded zone is switched off from the alarm. An exception is the zone of the external sensor 4 and the selection of the code. The signal from the "external" sensor 4 (usually a shock sensor) and an attempt to select a code always causes a short (5-7 seconds) activation of the alarm by the central unit 1.

3. Security mode with the engine running. In security mode, if programmed and authorized by the vehicle owner using the "service function settings procedure", the engine warms up. If the conditions described in clause 8 occur, the central unit disables the engine lock, starts the engine and enters the guard mode with the engine running. In this mode, the signals of the external sensor 4 (shock sensor) are ignored, however, the central unit 1 recognizes the signals of the engine start recognition unit and attempts to move 9. Having detected the engine stop signal, the central unit 1 disables the engine warm-up function, turns off the power, turns on the engine lock and goes into security mode 2.

4. The alarm is off. The system (central unit 1) is switched into this mode by contact identifying the code of one of the many keys registered in the system by touching the contact area of the code reader located on the vehicle's outer skin from modes 2 and 3 in the passive state or alarm state. The transition to this mode interrupts the alarm, and after opening any of the doors (by the signal from the door sensor), confirmation of disarming is confirmed by the user of the vehicle. Immediately after confirmation, the central unit 1 signals the causes of the alarm, if the latter took place. In this mode, accessories are turned on, but engine start remains blocked.

5. Ignition ON. This mode is turned on by conducting contact identification of the code of one of the many keys by touching the contact pad of the second-stage code reader 3. At the same time, the engine lock is turned off and the engine can be started.

6. The engine is running. The engine is started by closing the contact group for starting the engine 11 (by turning the ignition key to the "START" position).

7. Warming up the engine. After the lapse of time programmed in the “service function setting procedure” or cooling the engine below a threshold temperature, the “central unit” 1 ceases to receive signals from sensor 4 (shock sensor), then the ignition is turned on and the engine lock is turned off. The next step, the "central unit" 1 attempts to start the engine, including the starter for a period of not more than 8 seconds. Monitoring the appearance of the signal from the “engine start recognition and attempted movement recognition unit” 9, the central unit turns off the engine starter. After a successful start, the central unit instead of sensor 4 monitors the signals coming from block 9. In the event that the signal from the “engine start recognition unit and attempted movement” 9 disappears, the heating mode is canceled and the central unit 1 turns off the ignition, blocks the engine and switches to “Set to security. " A message about unsuccessful heating is recorded in the memory of the unit.
