Description

The present invention relates to the equipment of vehicles (TC) to prevent the unauthorized use (theft) or theft of the vehicle, in particular to anti-theft systems - immobilizers, designed primarily to directly counter theft.

Known anti-theft system for vehicles according to patent RU No. 2076815, B60R 25/10, containing a transportable part installed in the vehicle, including a microcontroller connected to the sensors of the impact on the vehicle, actuators, the first receiver and the first transmitter with the first inductor, and located the user of the anti-theft system (hereinafter referred to as the user) has a wearable part, including a second transmitter and a second receiver connected to each other with a second inductor, made with the possibility of its interaction with the first coil inductance. The first inductor is common for the first receiver and transmitter, and the second inductor is for the second receiver and transmitter. The first inductor is installed covertly in the calculation area of its interaction with the second inductor, and this area covers at least part of one of the seats in the passenger compartment or in the user cabin of the vehicle, in particular - part of the user's seat. In addition, the aforementioned first inductor can be installed in the back of the seat with an electrically open frame, in particular along its perimeter, in the manhole cover mounted on the roof of the passenger compartment or driver's cab and made of dielectric material, as well as in other places of the vehicle interior.

All elements of the wearable part can be mounted in a plastic card, and a second inductor can be installed around the perimeter of the card.

In the initial position, when the user, together with the wearable part and the ignition key, is located outside the vehicle, the ignition system of which is turned off by the lock, the microcontroller is connected to a power source. The memory of the microcontroller stores the algorithm of the system, and in the storage of the wearable part - the identification code. The oscillating circuit of the wearable part is tuned to the frequency of the pump generator, which is part of the mobile part.

The anti-theft system described above is one of the first systems that use the technology of contactless or radio frequency identification - Radio Frequency Identification - RFID (L. Stasenko "Modern Radio Frequency Identification Technologies. Review in the journal" Security Systems ", April - May 2004, p. 72-76).

This technology is implemented in the line of widely known anti-theft security systems, serially produced by the applicant company under the Black Bug ^® trademark since 1995 ("Automotive Security Systems", "Altonika" Catalog, 2003).

Passive transponders made in the form of plastic cards, petals or miniature capsules embedded in the ignition key or key fob, as well as active (with an autonomous power source) electronic transponder tags ("Car Security Systems") are used as a wearable part in these systems. Catalog "Altonika", 2008, p. 54, 55, www.altonika.ru).

The transportable part of such RFID devices (often called induction type devices) contains a reader with a “pump” generator, which provides irradiation of the wearable part and the accumulation of energy potential for the subsequent formation of packages containing an identification code.

The disadvantages of the anti-theft system described in the aforementioned patent, as well as other anti-theft systems using RFID devices of induction type, are the large dimensions of the antenna, which complicate the installation of the transportable part in the vehicle compartment, and the low speed of information exchange between the transportable and wearable parts of the RFID device, which limits the ability to achieve a sufficiently high cryptographic strength of the signal.

Another significant drawback of the above anti-theft system is the need to use additional wires, which complicates the installation of the system, reduces the reliability of its operation and enables attackers to detect and neutralize the specified system.

Therefore, the next step in the development of anti-theft systems was the application in them, along with RFID devices, of anti-theft controlled relays that implement HOOK-UP ^® and WAIT UP ^® technologies.

The indicated anti-theft (remotely controlled) relays are secretly installed in the gap of the circuits, allowing to block the movement of the vehicle (ignition circuits, fuel supply and other similar circuits). They do not allow the vehicle to move normally until the vehicle user (vehicle owner or persons authorized by him) is identified by an electronic tag.

The uniqueness of these relays lies in the fact that they do not connect to the central control unit of the anti-theft alarm system using additional wires that unmask these relays. In addition, the WAIT UP relay protects the vehicle at a fundamentally new level - motion blocking during theft occurs when the vehicle begins to move, but on a fixed vehicle this relay does not manifest itself. This makes it impossible to find a relay blocking the movement of the vehicle, using diagnostic equipment (by "dialing"). Coded signals are sent via the standard vehicle power bus.

The first domestic patent for an invention is RU No. 2160196, B60R 25/00, which implements these technologies, belongs to the applicant company and was registered in 2000.

According to the said patent, the anti-theft system for the vehicle contains a processor unit for processing incoming information and command synthesis, the first input of which is connected to the power bus through the ignition switch, and the first output and second input are connected with the possibility of requesting and reading the unlock code, respectively, with the input and output of the RFID device , which includes the wearable part (electronic tag) and the transportable part (receiver) connected by the radio channel, the second output of the processor unit for processing the incoming information and the synthesis of com ND through the communication channel is connected to the inputs of the modules of the blocking of the functional organs of the vehicle, each of which has a controlled relay connected by contact groups to the functional body of the TS and sequentially connected matching block with the communication channel and a decoder, while the voltage inputs of each module of the blocking of the functional organs of the TS are connected to the first input of the processor unit for processing incoming information and command synthesis, while at least one node blocking the functional organs of the vehicle contains a delay element and a motion sensor, and each blocking module is a memory element, the first input of the memory element connected to the output of the decoder, the second input connected to the output of the motion sensor, the third input through the delay element connected to the first input of the processing unit for processing incoming information and command synthesis, and the output is connected to the control input of the controlled relay.

The combination of the advantages of the remote-controlled relays HOOK-UP ^® and WAIT UP ^® is realized, in particular, in the vehicle protection system against unauthorized use according to patent RU No. 2237585, B60R 25/00.

The disadvantages of the above anti-theft systems are due to the use of induction-type RFID devices in them, which is associated with the large dimensions of the antenna, the short range and low cryptographic strength of the signals.

These shortcomings are eliminated in a new generation of anti-theft systems that use radio data exchange between the electronic tag and the nodes of the vehicle at ultra-high frequencies (microwave), in particular, using the allowed range from 2400 to 2483.5 MHz.

The main components of these anti-theft systems are an electronic microwave transceiver-tag with an autonomous power source (battery), a control unit and traffic blocking modules, which include transceivers that allow two-way data exchange without using the vehicle’s standard wiring and additional wires.

The specified radio data exchange is carried out in dialogue mode at different frequencies, randomly selected in the range from 2400 to 2483.5 MHz. This technical solution leads to an extremely high cryptographic strength of the signal.

Anti-theft systems of this class include SkyBrake DD (www.autonams.lv), StarLine Smart 2.4G (www.twage.ru), and a number of others. Anti-theft system SkyBrake DD is the closest analogue of the present invention.

The SkyBrake DD system is controlled remotely using a miniature electronic tag located at the user’s place, which is a programmable transceiver that regularly broadcasts using the Double Dialogue (DD) technology and communicates with the control unit installed in the vehicle. According to the developers of this system, the use of DD technology almost 100% guarantees the protection of the anti-theft system from electronic "hacking".

The particularly small dimensions of the electronic tag allow you to control the anti-theft system without any action on the part of the user, and the small size of the control unit allows you to securely hide it in the vehicle. High secrecy of the installation, in which the user of the vehicle may not even know in which place the vehicle control unit is installed, is an undoubted advantage of the anti-theft systems SkyBrake DD.

However, this feature can serve the user and poor service - in case of loss of electronic tags.

The present invention is aimed at eliminating this drawback while maintaining the above advantages of the closest analogue.

The essence of the invention lies in the use of a multifunctional indicator unit, which allows:

- inform the user about the status of the various components of the anti-theft system in which the transceivers are installed, in particular about charging the battery of the electronic tag;

- manually enter the secret code in case the user loses an electronic tag (the code is unique and can be changed at any time by the user of the vehicle);

- relay the signals of the electronic tag to the traffic blocking modules of the vehicle, which significantly increases the reliability of the anti-theft system, since the characteristics of radio communications in the microwave range are subject to temperature dependence, as well as depending on the relative location of the transceivers and structural elements of the vehicle.

The subject of the present invention is an anti-theft system containing one or more electronic tags, a control unit, to the first input of which an ignition bus is connected, as well as blocking modules, each of which contains a transceiver and a controlled relay, configured to connect to the functional organs of the vehicle, the transceiver and electronic tags are made with the possibility of dynamic identification data exchange, while an indicator unit with a relay is introduced into the anti-theft system a speaker, a microprocessor, a system status indicator and a control button, and the control unit is installed in the blocking module, while the second input of the control unit is connected to the output of the transceiver, the control input of which is connected to the first output of the control unit, the second output of which is connected to the input of the controlled relay, relay made with the possibility of dynamic identification data exchange with the aforementioned electronic tags and transceivers and is connected by the output to the information input of the microprocess a quarrel, the first output of which is connected to the input of the repeater, the control button is connected to the first control input of the microprocessor, the output of which is connected to the input of the system status indicator, and the second control input is connected to the ignition bus.

Private essential features of the invention are the following:

electronic tags, a repeater and transceivers are configured to operate in the microwave frequency range, in particular in the allowed range from 2400 to 2483.5 MHz;

managed relays included in the blocking modules are made in accordance with the HOOK-UP and / or WAIT UP technologies;

dynamic identification data exchange channels between electronic tags and a repeater, electronic tags and transceivers, as well as between transceivers and a repeater are made in accordance with the technology of dynamic identification dialogue (DID).

The objective of the invention is the creation of an anti-theft system, more reliable and easy to use than the system, which is its closest analogue.

The technical result is ensured thanks to the aforementioned multifunctionality of the indicator unit, which allows achieving advantages over the closest analogue while maintaining its advantages compared to anti-theft systems using RFID devices of induction type.

The essence of the invention is illustrated in the drawing, which shows a structural diagram of the proposed anti-theft system.

The following notation is used in the drawing: 1 - electronic tag; 2 - indicator unit; 3 - blocking module; 4 - transceiver; 5 - repeater; 6 - system status indicator; 7 - control button; 8 - microprocessor; 9 - control unit; 10 - controlled relay.

The anti-theft system under consideration contains one or more electronic tags 1, one or more blocking modules 3 and an indicator unit 2. Electronic tags 1, locking modules 3 and an indicator unit 2 are the three main components of the anti-theft system under consideration.

Each of the blocking modules 3 contains a control unit 9, the first input of which is connected to the ignition bus, a transceiver 4 made with the possibility of dynamic identification data exchange with electronic tags 1, and a controlled relay 10 made with the possibility of connection to the functional organs of the vehicle. The output of the transceiver 4 is connected to the second input of the control unit 9. The control input of the transceiver 4 is connected to the first output of the control unit 9, the second output of which is connected to the input of the controlled relay 10.

The indicator unit 2 contains a microprocessor 8, a control button 7, a system status indicator 6, and a repeater 5, which is configured for dynamic identification data exchange with the aforementioned electronic tags 1 and with the transceivers 4 included in the blocking modules 3. The output of the relay 5 is connected to the information input of the microprocessor 8. The first output of the microprocessor 8 is connected to the input of the relay 5. The control button 7 is connected to the first control input of the microprocessor 8, the output of which is connected to the input of the system status indicator 6, and the second control input is connected to the ignition bus.

A feature of electronic tags 1 is that they are configured to operate on DID technology in the microwave frequency range, for example, in the allowed range from 2400 to 2483.5 MHz. As noted above, such electronic tags 1 began to be used in security and anti-theft systems relatively recently, however, at present they have already firmly taken their place in the commercial market. In particular, similar electronic tags 1 are used in the line of anti-theft systems SkyBrake DD (www.autonams.lv), which are the closest analogue of the anti-theft system under consideration.

The controlled relays 10 included in the blocking modules 3 are made in accordance with the HOOK-UP and / or WAIT UP technologies and are widely used in many security and anti-theft systems commercially available by the applicant company. Together with the transceiver 4 and the control unit 9, they are a new generation of remotely controlled relays, HOOK-BASTA-Z and WAIT-BASTA ("Automotive Security Systems. Catalog" Altonika ", 2008, p.18, 19), based on which implemented blocking modules 3.

With regard to the newly introduced indicator unit 2, the possibility of its practical implementation is confirmed by successful tests of prototypes (as part of the anti-theft systems BS-911Z and BS-911W) carried out at the applicant enterprise as part of the R&D BASTA (Anti-theft system BASTA. BS-911Z and BS-911W models. User manual, Altonika, 2008).

The channels of dynamic identification data exchange between electronic tags 1, relay 5 and transceivers 4, which are part of blocking modules 3, are made in accordance with DID technology, which is also widely used in serial products of the applicant company, for example, in the line of security and anti-theft systems BLACK BUG SUPER ("Car Security Systems", Catalog "Altonika", 2008, pp. 8-10).

Thus, all the components of the system in question, indicated in the drawing, are known and have proven themselves in practice. Therefore, the possibility of practical implementation of the proposed technical solution is not in doubt.

The anti-theft system under consideration works as follows.

The essence of the anti-theft system is to communicate with each other over the air of electronic tags 1, indicator unit 2 and blocking modules 3. Electronic tag 1 is located at the user and constantly emits microwave signals. To enable or disable anti-theft functions, no action is required from the user. The anti-theft system is controlled automatically.

Upon detection of electronic tag 1, the system allows you to freely use the vehicle. If the electronic tag 1 is not detected, then the anti-theft system using the blocking modules 3 blocks the operation of the engine.

Reception from the electronic tag 1 of the signals containing the identification code is carried out by the transceiver 4 installed in the blocking module 3. In addition, the signal of the electronic tag 1 is received by the repeater 5, which is part of the indicator unit 2. The repeater 5 supplements with service information and again sends the signal received from the electronic tag 1 to the radio air. Thus, the transceiver 4 can receive as a signal generated by the electronic tag itself 1, and the signal sent by the repeater 5. Such a “two-channel” can significantly improve the reliability of radio information exchange between the electronic tag 1 and the blocking module 3 (which includes a receiving eredatchik 4).

The indicator unit 2, installed (in a conspicuous place, or, at the request of the user, more discreetly) in the vehicle compartment, contains an indicator 6 of the system status. It displays the status of the anti-theft system using the luminous icons on the front panel of the indicator unit 2 and by supplying the appropriate sound signals. At the same time, the front panel of the indicator unit 2 acts as a control button 7. By clicking on it, you can enter the secret code of the anti-theft system (for example, in case of loss of electronic tag 1), as well as configure the anti-theft system (this function is described below).

Examples of possible options for displaying the system states used in the anti-theft system BASTA models BS-911Z and BS-911W (www.altonika.ru) are presented in table 1.

Examples of possible options for sound indication in the indicator 6 of the system status are shown in table 2.

The display of information in the system status indicator 6 and the relay of signals from the electronic tag 1 to the blocking module 3 are controlled by a microprocessor 8.

As an example, we consider the main modes of operation of indicator unit 2 in the above-mentioned models of the anti-theft system BASTA.

1 Start of movement - "Immobilizer" mode

Auto engine lock is activated a few seconds after the ignition is turned off. The control unit 9, which is part of the blocking module 3, responds to the ignition off. The control unit 9 acts on a controlled relay 10, which carries out the engine blocking. The microprocessor 8, which is part of the indicator unit 2, also responds to the ignition off signal. The microprocessor 8 acts on the system status indicator 6. In this case, the icon 1 on the front panel of the indicator unit 2 starts to flash with a certain frequency in red.

To disable the "Immobilizer" mode, the repeater 5 (in the indicator block 2) and the transceiver 4 (in the blocking module 3) must recognize the electronic tag 1. Depending on the settings of the anti-theft system, the electronic tag 1 is searched either immediately after turning on the ignition, or after pressing to the front panel (control button 7) of the indicator unit 2 with the ignition on. On the radio channel, the repeater 5 informs the transceivers 4 of the presses of the control button 7.

Between the electronic tag 1 and the transceiver 4 (directly or through the repeater 5), a dynamic identification dialogue is carried out, as a result of which the control unit 9, to which the signal from the ignition system is applied, recognizes the vehicle user identification code and supplies power to the winding of the controlled relay 10.

When the contacts of the controlled relay 10 are closed (or opened), the functional bodies of the vehicle are unlocked, which impede the operation of the engine, and the movement of the vehicle becomes possible.

In the case of controlling the "Immobilizer" mode using the control button 7, the search for the electronic tag 1 begins after pressing the specified control button 7.

If the electronic tag 1 is recognized, the system status indicator 6 beeps “electronic tag found”, and the icon 1 on the front panel of the indicator unit 2 glows blue for several seconds. This shows that movement can begin.

2 Continued Driving - AntiHiJack Mode

AntiHiJack mode (protection against capture) is an automatic continuous search for electronic tag 1 with the ignition on in order to identify the user to prevent possible unauthorized operation of the vehicle.

Depending on the settings of the anti-theft system, the search for electronic tag 1 in AntiHiJack mode can be carried out in one of the following ways:

- from the moment the ignition is turned on and off;

- from the moment the door is opened with the ignition on and until the expiration of several minutes after it is closed.

If, in the process of constant search, the repeater 5 and the transceiver 4 cannot detect the electronic tag 1 for about 1.5 minutes, then the icon 1 on the front panel of the indicator unit 2, by the command of the microprocessor 8, starts flashing red with increasing frequency for several tens of seconds. In addition, the microprocessor 8 sends a command to the indicator 6 of the system status to enable warning sound signals "no electronic tag." An example of these signals is shown in Table 2. If after another 0.5 min the electronic tag 1 is not found, then the microprocessor 8 sends a command to block the engine through the relay 5 to the blocking module 3. This command is received by the transceiver 4 and transmitted to the control unit 9, which accordingly acts on the controlled relay 10 in order to block the engine.

There are other possible options for the considered anti-theft system, shown in the drawing.

As follows from the foregoing, the proposed anti-theft system is very convenient in operation for the user of the vehicle.

All that is required from the user of the vehicle is to always carry an electronic tag 1. Moreover, the miniature dimensions of the electronic tag 1 allow you to store it in any place convenient for the user. Even if the electronic tag 1 is lost, the user still has the opportunity to use his vehicle by entering the secret code into the microprocessor 8 using the control button 7.

Another advantage compared to the closest analogue - reliability of operation - is ensured by the use of a relay channel for the exchange of information between electronic tag 1 and blocking module 3. The presence of these additional features favorably distinguishes the proposed anti-theft system from its closest analogue.

Thus, the task is solved - an anti-theft system can be created more reliable and convenient in operation than the system, which is its closest analogue.

The technical result is ensured by the multifunctionality of the indicator unit 2, which allows to achieve the above advantages over the closest analogue while maintaining its advantages compared to anti-theft systems using RFID devices of induction type.
