Description

The invention relates to techniques for preventing unauthorized use of a vehicle (TS) and is intended to signal attempts to unwanted entry into a vehicle.

The control equipment for the electronic system of protection against unauthorized use of the vehicle may include a wearable part, for example, transponders (tags) and / or key rings held by the owner of the vehicle and authorized persons (hereinafter referred to as vehicle users) and a part (i.e. installed on the protected vehicle) of the vehicle , which contains a logic module, a user warning unit, an immobilizer relay body, a reader, the input of which is connected to the output of the request strobe of the logical module, the relay control output of which is connected to the immobilizer relay body, the alarm control output to the input of the user warning unit, the actuator control group output to the control bus group, and the signal sensor group input is connected to the signal bus group (EP No. 0635408, 60 R 25/10, E 05 B 49/00, 07/22/1993).

The disadvantage of the above technical solution is that, while protecting the vehicle from theft, hijacking or theft, it does not improve the usability of the vehicle for its users themselves, since it does not allow offering each user service capabilities (for example, starting / stopping the engine, position adjustment seats, tilt steering column, etc.).

The main direction of solving this problem is the introduction of a programming mode for controlling the electronic protection system of the vehicle. So, there is a known method of controlling the vehicle’s electronic protection system, which provides for the preliminary recording of information about the configuration and service settings of the system in the permanent memory (ROM) of the main transponder (Master-tag), entering the programming mode using this Master-tag, linking the vehicle’s immobilizer with a spare tag and the subsequent recording of its code in the RAM of the immobilizer and in the ROM of the Master Tag (US No. 5416471, E 05 V 53/00, 05.16.1995).

However, the known method is characterized by limited capabilities that do not allow combining the comprehensive programming of the anti-theft and security parts of the vehicle’s electronic protection system with the creation of comfortable operating conditions by its user.

A comprehensive increase in the effectiveness of electronic protection of the vehicle against unauthorized use and improvement of the comfort of its operating conditions is achieved by the method of controlling the protection system of the vehicle from unauthorized use, according to which information about the configuration and settings of the security and anti-theft parts of the electronic protection system, remote control codes designed for remote control of the security part of the electronic protection system, remote engine start and rear service functions, codes of tags used for remote control of the anti-theft part of the electronic protection system with immobilizer shutdown, on the function of the keyfob buttons, the parameters of the paging channel that starts and blocks the engine, the priority of commands transmitted from the tags and through the paging channel, as well as about the parameters of the channels for performing service functions, place the Master tag in the read zone and copy information from the Master tag to the ROM electronic security system located on the vehicle, and to make changes to the operating modes of the specified electronic security system, either re-program the ROM of the electronic security system, or change the contents of the ROM of the Master tag and copy the updated information of the Master tag into the ROM of the electronic security system from it, carry out hidden wireless data exchange between a wearable electronic device embedded in the vehicle’s personal use and portable electronic devices embedded in separate security nodes and the anti-theft parts of the vehicle’s electronic system of protection against unauthorized use, while the exchange of data between the wearable electronic device and one or more portable electronic devices is carried out automatically as soon as the portable electronic device is within the reach of one or more portable electronic devices, while as the above portable and portable electronic devices use microchips that implement wireless data exchange technologies, for example B luetooth (RU No. 2185297, 60 R 25/00, 07.20.2003).

In recent years, wireless technologies have also become widespread, providing remote connection of a subscriber to a public telephone network, for example, to a GSM mobile network. These are the so-called picocell fixed-line networks deployed in the premises of enterprises, offices, warehouses, etc. (see, for example, US No. 2002/0132582, H 04 B 5/00, 09/19/2002).

However, devices of this type are not recommended for negotiating during the movement of the vehicle, because, holding a cell phone in their hands, the driver violates the rules of the road and creates a threat to other participants. In this regard, car kits for hands-free calling ("hands free" or "free hands") are widely used - devices that provide the vehicle driver with the opportunity to talk on a cell phone without holding it in his hands.

A typical hands-free kit for a vehicle includes a microphone, loudspeaker, cell phone holder, and connection cable. The use of the speakerphone kit on board the vehicle significantly reduces the likelihood of dangerous situations on the road.

The specified device class includes, for example, an automobile telephone device according to the application GB No. 2363287, B 60 R 25/10, G 08 B 25/10, H 04 M 11/04, 06/17/2000. Along with the capabilities of hands-free kits, the specified device also has anti-theft and security functions and service capabilities.

The presence of the above-described functionality in real-life control equipment for electronic vehicle protection systems, for example, commercially available by the applicant company, allows us to switch to an even higher level of safety and service capabilities of this class of equipment. This is achieved by forming radio channels for the exchange of data between a wearable electronic device embedded in any personal use item of the vehicle user and portable electronic devices embedded in any electronic nodes of the vehicle while using the speakerphone kit.

Already, on the market of consumer goods there are a number of personal items (cell phones, watches, electronic notebooks) equipped with microchips for wireless data transmission over distances of about 10-50 m. By purchasing such items and installing the corresponding microchips in the electronic nodes of the vehicle , the user gets the opportunity to provide automatic and completely hidden from visual observation, the transfer of control commands for security and anti-theft functions and service capabilities of electronic Istemi vehicle protection against unauthorized use. Commands begin to be transmitted as soon as a wearable electronic device embedded in a personal use item is within the reach of one or more portable electronic devices.

The specified technical solution is implemented, for example, in patent RU No. 2211159, 60 R 25/00, H 04 M 9/08, 08/27/2003, which describes a hands-free kit for vehicles containing a central control unit for the anti-theft alarm system, the first the input and output of which are connected to the vehicle anti-theft alarm system, and the second input and output is connected to the vehicle user phone number storage unit, the timer and power supply control unit, the input of which is connected to the third output of the central control unit of the anti-theft anti-theft system, and the output is connected n to the on-board power supply network, a voice message memory unit, the input of which is connected to the fourth output of the central control unit of the anti-theft alarm system, as well as one or more cell phones, a connecting cable with a microphone and a loudspeaker, a speakerphone control unit with an audio unit integrated in it alarm system and a Bluetooth communication node, configured to radio exchange data with one or more cell phones, equipped with Bluetooth communication nodes, an external control and programming unit a communication link with a built-in light indication unit, a voice command memory unit, a storage unit for ringing tones and service sound signals, an acoustic echo cancellation and suppression unit, and a radio mute or mute unit, while the speakerphone control unit is connected to the phone number storage unit and secret codes of users of the vehicle, with a memory block for voice messages, with a memory block for voice commands and with a block for storing ringtones and service audio signals, one of the outputs of the speakerphone control unit the plug is connected through the unit for muting or turning off the radio to the control input of the on-board audio system, and the other output of the speakerphone control unit through the noise reduction and acoustic echo cancellation unit and the connecting cable is connected to the microphone and loudspeaker, one of the inputs of the speakerphone control unit is connected to the vehicle ignition system, and the other input is to the output of the remote control and speakerphone programming.

This technical solution is selected as a prototype of the present invention.

The subject of the invention is a device for signaling an unauthorized exposure to glass of a vehicle, comprising a microcontroller, a microphone, a speakerphone control unit with a built-in first Bluetooth node, configured to wirelessly communicate with a similar second Bluetooth node embedded in a cellular telephone located on the vehicle, as well as the central control unit of the security and anti-theft system, which is connected with the security and anti-theft system and with the storage unit of telephone numbers of users of the vehicle, and to one of its inputs The corresponding output of the speakerphone control unit is connected, which is connected to the ringtone storage unit and to the telephone user phone storage unit, and the output of the voice message storage unit is connected to the input of the speakerphone control unit, the input of which is connected to the output of the central control unit of the anti-theft alarm system . The specified device also contains a series-connected amplifier, the input of which is connected to the microphone output, and a frequency filter, and a microcontroller includes a series-connected analog-to-digital converter (ADC), the input of which is connected to the output of the frequency filter, a microprocessor processing unit and a deciding device, the output which is connected to an additional input of the central control unit of the anti-theft alarm system, configured to select code messages about the degree of damage eniya glass and activation in anti-burglar system, depending on the extent of this warning or alarm zones of tampering glass TC.

The objective of the present invention is to enable timely warning of a remote user of the vehicle, located, for example, in the office or in the apartment, about unauthorized exposure to his vehicle (in the form of glass breaking).

The provided technical result consists in the detection and recognition of such an impact and timely alert the user to take the necessary measures to protect the vehicle.

The invention is illustrated in the drawing, which shows a structural diagram of the claimed device. The following notation is used:

1 - microphone; 2 - amplifier; 3 - frequency filter; 4 - ADC; 5 - microprocessor processing unit; 6 - a decisive device; 7 - microcontroller; 8 - central control unit of the security and anti-theft system; 9 - security and anti-theft system; 10 - block storage of telephone numbers of users of the vehicle; 11 - speakerphone control unit; 12 - block storage of voice messages; 13 - the first Bluetooth node; 14 - block storage ringtones; 15 - a second Bluetooth node; 16 - cell phone.

The claimed device contains a series-connected microphone 1, amplifier 2, a frequency filter 3 and a microcontroller 7, consisting of a series-connected ADC 4, a microprocessor processing unit 5 and a resolving device 6, the output of which is the output of the microcontroller 7 and connected to the central control unit 8 of the security and anti-theft control system. The input of the ADC 4 is the input of the microcontroller 7.

In the considered version of the claimed technical solution, it is assumed that the same microphone 1 is used as in the prototype device, that is, their differences are not significant.

The series-connected amplifier 2 and the frequency filter 3 are an operational amplifier and a filter, the amplitude-frequency characteristic of which provides rejection of both low-frequency noise and the upper part of the frequency spectrum. As a result, an analog chain of the specified amplifier 2 and the frequency filter 3 ensures transmission of the middle part of the spectrum of sound frequencies, in which the tones of sound signals, which are characteristic of glass impacts, the appearance and propagation of cracks, the formation and spilling of glass fragments, are concentrated.

Microphone 1, amplifier 2, and frequency filter 3 are standard radio components (see, for example, the Handbook for Carrying Out Electrical Circuits for ESKD, Moscow, Publishing House of Standards, 1989). As for microcontroller 7, the RG-1 device (hardware implementation of the inventive device for signaling unauthorized exposure to TS glass) developed by the applicant enterprise and intended for mass production uses one of the newest developments of Texas Instruments (USA) - 16-bit microcontroller MSP430F149 with low energy consumption, the design parameters of which provide the ability to work on board the vehicle. Currently, the specified microcontroller is already used in the samples of sound recognition devices RK-01 and RZ-1 developed at the applicant enterprise.

The RG-01 device is compatible with anti-theft alarm systems 9, commercially available by the applicant company and sold on the open market under the trademarks BLACK BUG® and REEF®, containing tamper sensors, alarm devices and actuating units, such as immobilizers. Each such system is controlled by the central control unit 8 of the security and anti-theft system.

The remaining functional units shown in the drawing are shared with the prototype device and are part of the REEF HP-1000 "Speakerphone Kit" series produced by the applicant company (certificate of conformity No. РОСС RU.ME30.B.01281).

Thus, the possibility of practical implementation of the claimed device is not in doubt.

Consider a device for signaling an unauthorized exposure to glass TS works as follows.

The role of the glass impact sensor in the claimed device is played by the microphone 1 installed in the vehicle interior. As already noted, a hands-free microphone, which is part of the prototype device, can be used. Microphone 1 converts the acoustic impact resulting from impacts on the glass and the effects of such impacts (crack propagation, destruction and falling of glass fragments), into an electrical signal that is fed to the input of an analog circuit consisting of a series-connected amplifier 2 and a frequency filter 3. Specified the analog chain selects the middle part of the spectrum of sound frequencies, in which the spectral components are concentrated, which are characteristic for the sounds of blows on the glass, the appearance and spread of cracks and rashes shattered glass.

The filtered signal is fed to the microcontroller 7, where it is subjected to analog-to-digital conversion to ADC 4, and then fed to the input of the microprocessor processing unit 5, in which spectral analysis of the selected portion of the signal spectrum is carried out, for example, by fast Fourier transform (B. Gold, Ch. Raider "Digital Signal Processing", Moscow, "Soviet Radio", 1973, ch. 6).

The presence of a number of harmonic components with a sufficiently large amplitude in the middle part of the spectrum of sound frequencies is typical for the sounds of each of the classes of signals distinguished by the claimed device:

- glass blows;

- creeping on glass cracks;

- rashes of glass fragments.

The determination of the class of exposure to glass is carried out using a decisive device 6 according to the rules established empirically, as a result of numerous experiments. For example, the results of spectral analysis are normalized and compared with some predefined thresholds. The ADC 4, the microprocessor processing unit 5 and the deciding device 6 are made in the form of a programmable microcontroller 7 that implements such a comparison. The specification of these rules is not the subject of this invention.

From the output of the deciding device 6, which is the output of the microcontroller 7, code messages for which the deciding device 6 determines the class of exposure to glass are fed to the additional input of the central control unit 8 of the anti-theft alarm system.

In the event that the deciding device 6 classified the external impact as glass blows, the warning level (zone) of the alarm is triggered and the central control unit 8 of the anti-theft alarm system activates the sound and light alarm units of the vehicle (for example, control units) in the anti-theft system 9 siren and headlights on) in the mode of giving warning sound and light signals. In addition, the central control unit 8 of the security and anti-theft system includes in the security and anti-theft system 9 nodes perimeter lock. That is, the anti-theft alarm system 9 locks on the vehicle all the doors, the trunk and the hood, and also completely raises all the windows. If blocking the perimeter is impossible, for example, as a result of strikes on a slightly open glass it does not rise completely, then the anti-theft alarm system 9, after a period of time necessary to block the perimeter, informs the central block 8 of the anti-theft system about the impossibility of complete blocking. This signal puts the central unit 8 control anti-theft system in alarm mode.

In those cases when the decisive device 6 classified the external impact as the spreading of cracks and / or spilling of glass fragments, the central control unit 8 of the anti-theft system immediately goes into alarm mode.

In the alarm mode, the central control unit 8 of the anti-theft system triggers the operation of the nodes of the security and anti-theft system 9, which prevent entry into the vehicle. The sound and light alarm components included in the security and anti-theft system 9 begin to give out more powerful alarms than in the mode of giving warning signals in order to attract the attention of people around.

In addition, in the alarm mode from the central control unit 8 of the security and anti-theft system, the security and anti-theft system 9 and the storage unit 10 of the telephone numbers of the vehicle users receive respectively commands to enable certain functional units of the security and anti-theft system (for example, to turn on the immobilizer) and commands that activate the search for the phone number of the user with the highest established priority (for example, the owner of this vehicle).

In accordance with the telephone number found in the block 10 for storing the telephone numbers of the vehicle users, a dialer command is generated in the speakerphone control unit 11. At the same time, upon a command from the central control unit 8 of the anti-theft alarm system, the voice message storage unit 12 selects the required call to the vehicle user, which is transmitted to the speakerphone control unit 11 for subsequent radiation on the high-frequency carrier (2.4 GHz) using first Bluetooth node 13.

Instead of or together with a voice message, the user may be given some alarming melody. The voice message storage unit 12 is additionally notified by the speakerphone control unit 11 of the need to generate such a message. After that, the speakerphone control unit 11 requests the ringtone storage unit 14, receives a response from it in the form of a corresponding ringtone and, using the first Bluetooth node 13, transmits it to the radio.

The signals of the radio call of the user of the vehicle enter the second Bluetooth node 15, built into the cell phone 16 located in the cabin (or in the trunk) of the vehicle, which transmits them over the mobile network (for example, GSM standard) to the remote user of the vehicle.

However, dialing to the appropriate user is not always successful. If there is no communication with the remote user during the set dial-up time, the second Bluetooth node 15 transmits a radio signal to the first Bluetooth node 13 over the air. After that, the speakerphone control unit 11 (which includes the first Bluetooth node 13) transmits a command to temporarily change the priority to the unit 10 for storing telephone numbers of users of the vehicle. In turn, the central unit 8 controls the anti-theft alarm system receives a command activating the repeated search for the user's phone number with the highest priority (taking into account the temporary change in priority in the block 10 for storing the phone numbers of the TS users). In the end, one of the users of the vehicle receives a radio call alarm.

Having received the indicated signal, the vehicle user must evaluate the situation and take appropriate actions to protect the vehicle. For example, he can call the police on call (to the 02 service) or contact one of the citywide anti-theft alarm system operators.

If the vehicle’s engine blocking means are provided for blocking the vehicle’s engine through cellular mobile communication channels and the user wishes to use this vehicle’s protection system, the vehicle’s engine blocking signal transmitted from the user's telephone is transmitted to the cellphone 16 located onboard the vehicle and then through the built-in vehicle the second Bluetooth node 15, this signal is transmitted over the air to the first Bluetooth node 13 located in the vehicle compartment, which is integrated in the speakerphone control unit 11. From the speakerphone control unit 11, the vehicle engine blocking signal enters the central control unit 8 of the anti-theft alarm system. From it, the corresponding blocking command is transmitted to the anti-theft alarm system 9 and blocks the movement of the vehicle. This greatly facilitates further actions to search for and intercept a stolen vehicle.

Thus, the introduction into the prototype device of an analog circuit consisting of an amplifier 2 and a frequency filter 3, and a microcontroller 7, the output of which is connected to an additional input of the central control unit 8 for controlling the anti-theft alarm system, allows us to solve the problem, namely, to provide a remote user of the vehicle , finding, for example, in an office or in an apartment, the ability to quickly respond to attempts by attackers to break the glass and penetrate the vehicle. The ensured technical result consists in the detection and recognition of such an impact and in a timely alarming user to take the necessary measures to protect the vehicle.

The specified set of features has novelty and utility, which allows us to classify it as an invention.
