Description

The proposed device relates to transport equipment and can be used to prevent unauthorized use or theft of vehicles and transported goods.

Known systems and devices for preventing unauthorized use or theft of vehicles are based:

- on the use of sound signaling devices (autosvid. USSR No. 1634557; RF patents No. 20111575, 2033354, 2040416 and others);

on the use of a code device and a radio channel through which alarming information is transmitted (RF patent No. 2021927 and others);

on capturing a hijacker using a transport pneumatic system (RF patent No. 2050294 and others);

using complex signals transmitted over the radio channel and direction finding of a stolen vehicle by the phase method (RF patents No. 2006394, 2033353, 2042548, 2061321, 2061322, 2061323, 2185298 and others).

Of the known systems and devices closest to the proposed one is the "Device for protecting a vehicle from theft and theft" (RF patent No. 2185298, 60 R 25/04, 2000), which is selected as a prototype.

The principle of protecting a vehicle in motion and static state, according to the known device, is based on the fact that when the ignition is turned on unauthorized, as well as when doors, hood and trunk are opened to steal individual elements, the radio channel is switched on to transmit to the control room alarm phase-shift signal. The device provides increased efficiency and reliability of vehicle protection.

However, this device does not provide control over the transportation of goods transported by a vehicle. Ensuring the safety of goods transported by vehicles is an important task. To date, the losses associated with theft in transport are calculated in huge numbers. In addition to protecting cargo from atmospheric and mechanical influences, container shipping allows to some extent reduce the likelihood of theft due to sufficiently powerful locking mechanisms. At the same time, statistics show that thefts from containers occur during both authorized and unauthorized opening. With authorized openings, direct participants in the transportation and control of goods can take part in the theft: movers, drivers, forwarders, security guards, customs officers, etc.

Unauthorized opening can occur at all stages of transportation: during loading, while driving, in parking lots, during inspections, etc. Under these conditions, the task of completely eliminating thefts becomes impossible, however, the introduction of a control system that informs the transportation control center of all facts of opening the containers with an indication of the time, place, identification parameters of the opening (authorized or not, password of the cracker, etc.) allows for investigations determine the circle of persons involved in the authorized autopsy, as well as quickly identify the fact of an unauthorized autopsy and take appropriate measures. At the same time, supplying each container with a complex and expensive access control system and a powerful communication system with a transportation control center seems inappropriate. It seems more rational to use the capabilities of the existing system for monitoring their movement on vehicles.

An object of the invention is to expand the functionality of the device by ensuring the safety of goods during transportation due to continuous monitoring of the condition of a mobile vehicle and the cargo located on it and the transmission of operational messages in emergency situations, with the possibility of taking emergency measures when the vehicle deviates from the route, triggering an alarm cargo or driver messages.

The device protects the vehicle from theft and theft works as follows.

Containers are installed on the vehicle 2, which are equipped with a security alarm system 56. At the end of loading, the container is closed, and the operator uses the keypad 49 on the access control panel 48 to enter his operator code, which is fed to the first input of the code generator 51, the second input of which is connected to the output of the memory unit 52, the code generator 51 is a register, some of which (operator code) is filled in from the keypad 49, part of the digits (code that allows disabling and activating the security alarm) are stored in the remote control (in memory block 52) and the operator does not know it. The generated code M ₂ (t) (Fig. 4, a) containing information about the operator code and the code enabling the alarm system 56 to be activated, from the output of the driver 51 of the code is fed to the first input of the phase manipulator 53, to the second input of which a high-frequency oscillation is supplied the output of the generator 52 high frequency (Fig.4,6)

U ₃ (t) = ν ₃ · Cos (ω ₃ t + φ ₃ ), 0≤t≤T ₃ ,

At the output of the phase manipulator 53, an FMN signal is generated (Fig. 4, c)

U ₄ (t) = ν ₃ · Cos [ω ₃ t + φ _к3 (t) + φ ₃ ], 0≤t≤T ₃ ,

where φ _к3 (t) = {0, π} is the manipulated component of the phase, which displays the law of phase manipulation in accordance with the modulating code M ₂ (t), which, after amplification in the power amplifier 54 by means of the transmitting antenna 55, is transmitted to the ether, received by the receiving antenna 57 and through a high-frequency amplifier 59 enters the first inputs of the multipliers 60 and 61. The reference voltage is applied to the second input of the multiplier 61 (Fig. 4, d)

U ₀ (t) = ν ₀ Cos (ω ₃ t + φ ₃ ), 0≤t≤T ₃ .

The output of the multiplier 61 produces a resulting voltage

U _Σ (t) = ν _Σ · Cosφ _k3 (t) + ν _Σ · Cos [2ω ₃ t + φ _к3 (t) + 2φ ₃ ],

where ν _Σ = _^1/2 K · ν · ν _{0 3,}

K is the transmission coefficient of the multiplier.

Analog modulating code M ₂ (t) (figure 4, d)

U _H2 (t) = ν _Σ · Cosφ _k3 (t),

is allocated by the low-pass filter 63 and fed to the second input of the multiplier 60, at the output of which a harmonic voltage is generated (figure 4, g)

U ₀ (t) = ν ₄ · Cos (ω ₃ t + φ ₃ ) + ν ₄ · Cos [ω ₃ t + 2φ _к3 (t) + φ ₃ ] = 2ν ₄ · Cos (ω ₃ t + φ ₃ ) = ν ₀ Cos (ω ₃ t + φ ₃ ),

where ν ₄ = _{^1/2 3} K · ν · ν _Σ; ν ₀ = 2ν ₄ .

This voltage is extracted by a narrow-band filter 62 and supplied to the second input of the multiplier 61. Therefore, the multipliers 60 and 61, the narrow-band filter 62 and the low-pass filter 63 form a universal FMN signal demodulator. In this case, the reference voltage required for synchronous detection is extracted directly from the received PSK signal U ₄ (t). The proposed demodulator of the FMN signal is free from the phenomenon of "reverse work" inherent in all known demodulators.

An analog of the modulating code U _n2 (t) (Fig. 4, e) is supplied from the output of the low-pass filter 63 to the control unit 65, which stores and compares the operator code and the code allowing the security system 56 to be activated. When they coincide, the control unit 65 generates a signal to activate the alarm (not shown in the drawing).

An access sensor 64 is connected to the second input of the control unit 65, which is designed to signal any attempts to open the container. The access sensor 64, for example, is a contact group mounted on the doors of the container and connected to the control unit 65.

Consequently, the code message receiver 58 is intended to receive code messages sent from the access control panel 48 by a person turning on or off the container security alarm with authorized access to it.

In the block 50 of the memory enter information containing a code corresponding to the inclusion, and a code corresponding to the disarming of the alarm.

The control unit 65 is a means for controlling the opening of the container and storing information, containing a code that enables the alarm, and an operator code.

The stored code U _Н2 (t) (Fig. 4, e) is supplied to the first input of the phase manipulator 68, the second input of which is fed by a high-frequency oscillation from the output of the high-frequency generator 67 (Fig.

U ₅ (t) = ν ₅ Cos (ω ₅ t + φ ₅ ), 0≤t≤T ₅ .

At the output of the phase manipulator 68 formed FMN - signal (figure 4, g)

U ₆ (t) = ν ₅ Cos (ω ₅ t + φ _к5 (t) + φ ₅ ), 0≤t≤T ₅ ,

which, after amplification in the power amplifier 69, is transmitted to the air via the transmitting antenna 70, is received by the antenna 3, and through the receiver 5 and the pairing device 7 is fed to the operational communication console 71, which contains an indicator for turning on the vehicle's onboard equipment 2, a call button for the dispatcher to speak , a button for the signal for terminating voice communication with the dispatcher, buttons for operational messages of the driver, for example, “Emergency”, “Call for medical assistance”, “Attack”, etc., a text indicator of the message from the control room KTA, burglar alarm status indicators corresponding containers.

On the remote control 71 of the driver’s operative communication, in this case, an indicator lights up to indicate that the alarm has been activated and the container is in normal condition. Similar actions are performed with all containers.

The vehicle’s on-board equipment generates a signal containing information about the code of the container and the vehicle, the operator code, and information about the activation of the security alarm. Through the radio station 6, the signal is transmitted to the control room 14, where it is picked up by the antenna 16 and through the radio station 18, the interface device 19 and the personal computer 20 are sent to the documentation device 21 and display 22, where the container closure time, the container code, and the operator code that closes are recorded , vehicle number, etc.

The vehicle is sent to the route, the schedule of its movement and estimated coordinates in time are determined and known at the control station 14. On the route of the vehicle, the control unit 65 generates a signal containing information about the normal state of the alarm system 56, which is periodically transmitted via the transmitter 66 to the receiver 5, and then through the pairing device 7 is fed to the remote control 71 operational communications.

Therefore, the presence of the container is continuously monitored by the driver on the remote control 71 operational communications.

On the vehicle, through the receiver 5 with the receiving antenna 3, its current coordinates are determined. For this, the signals of the Navstar navigation system are used. The structure of this system includes the space segment, consisting of 24 spacecraft, a network of ground-based stations for monitoring their work and the user segment (navigation receivers). All 1 · j satellites (j = 1, 2, ..., 24) are autonomous and emit phase-shift (FMN) signals

U _c (t) = ν _c · Cos [ω _c t + φ _к (t) + φ _с ], 0≤t≤Tc,

where φ _к (t) = {0, π} is the manipulated phase component that displays the phase manipulation law in accordance with the modulating code M (t) (C / A code) 1023 characters long.

The receivers 5 and 17 of the GPS signals sequentially capture and process the FMN signals of each satellite from the selected constellation.

The microprocessor 8, which is part of the on-board vehicle complex, performs two functions: it serves the GPS signal receiver 5 and makes navigation calculations.

To determine the two coordinates of the place (latitude and longitude) and time, measurements from three satellites are required. Information from the fourth "extra" satellite may be necessary during various maneuvers of the vehicle, when it is possible to replace the signals of one or more satellites.

To improve the accuracy of determining the location of the vehicle, the differential correction method is used, which is based on the application of the principle of differential navigation measurements, known in radio navigation. The differential mode allows you to set the coordinates of the observed vehicle with an accuracy of 5 m in a dynamic navigation environment and up to 2 m in stationary conditions.

The exchange of information between the control room 14 and the monitored vehicle 2 is carried out via a radio channel and / or through a relay 13 installed in the central part of the city.

In the absence of a periodic signal from the alarm system 56 or other emergency situation, the driver presses the corresponding button on the operational communication console 71. From the remote control 71, emergency information is received at the input of the pairing device 7, where this information is supplemented with information about the vehicle code, about the current coordinates of the vehicle in a signal that is fed to the input of the radio station 6 from the output of the pairing device 7, and is broadcast and received by the radio station 18. Information is extracted from the received signal, which is analyzed and a decision is made on operational assistance.

In the event of an emergency, for example, when the current coordinates of the vehicle deviate from the set values for acceptable values or when a corresponding signal message is received from the control panel 71 of the operational communication system or alarm system 56, the current and set coordinates of this mobile vehicle are displayed on the electronic map of the display 22. In the presence of an alarm message, the semantic content and time of transmission of the alarm message, vehicle number, as well as a detailed map of the area are also displayed. Based on the analysis of the information received, the dispatcher makes a decision aimed at providing operational assistance to the driver and ensuring the safety of the transported container.

In case of unauthorized exposure to the guarded vehicle 2, which is expressed, for example, in opening doors, trunk, hood, glass removal, towing the vehicle and cargo, as well as moving it on its own, the first 35 and second 37 windings are connected to the battery 32 relay. In this case, the button switches of the doors 39, or the windows 40, or the trunk 41, or the hood 42, or the pendulum switch 43 are closed. This can only happen if the switch 36 is closed, which is located in a secret place known only to the driver of the vehicle. The latter, leaving the vehicle interior, closes the switch 36 and thereby puts the vehicle under protection. When leaving the passenger compartment of the vehicle, the driver opens the door and turns on the audible signaling device 38 and signal (parking) lamps 44-47, making sure that the security device is operational.

Therefore, in case of unauthorized exposure to the vehicle, relay 37 is activated, contacts 37.1 and 37.2 are closed. At the same time, an audible signaling device 38 and signaling (marker) lamps 44-47 are turned on, which attracts the attention of law enforcement officials and others.

At the same time, the supply voltage is supplied to the transceiver unit 10. In this case, the high-frequency generator 23 is turned on, which generates a high-frequency oscillation (Fig. 3, a)

U ₁ (t) = ν ₁ · Cos (ω ₁ t + φ ₁ ), 0≤t≤T ₁ ,

which is fed to the first input of the phase manipulator 25, to the second input of which a modulating code M ₁ (t) is supplied (Fig. 3, b) containing information about the make, number, color of the vehicle, its location and information about the owner (driver) of the vehicle facilities. At the output of the phase manipulator 25, a phase-shift (PSK) signal is generated (Fig. 3, c)

U ₂ (t) = ν _l · Cos [ω ₁ t + φ _кl · (t) + φ ₁ ], 0≤t≤T ₁ ,

which through the power amplifier 26, the antenna switch 27 and the antenna 4 is radiated into space.

This signal directly or through a relay 13 is received at the control room 14, demodulated, decoded and recorded in an electronic journal or on an electronic map, which displays the location of the stolen vehicle and its movement. At control room 14, a control signal is generated that is similar to an alarm, i.e. having the same carrier frequency ω ₁ and the same modulating code M ₁ (t).

Therefore, the alarm signal is re-emitted at the control room 14 using the radio station 18 and antenna 16. The specified signal from the output of the antenna 4 through the antenna switch 27 and the high-frequency amplifier 28 is fed to the first input of the phase detector 29, the second input of which is from the second output of the high generator 23 frequency oscillation U ₁ (t) as a reference voltage. The output of the phase detector 29 is formed of a low-frequency voltage (Fig.3, g)

u _н1 (t) = ν _н1 · _{Cosφ к1} (t), 0≤t≤T ₁ ,

where ν _H1 = _^1/2 K ₁ · ν ₁ ²

K ₁ - the transfer coefficient of the phase detector, proportional to the modulating code M ₁ (t) (Fig.3, b). This voltage is supplied to the first input of the correlator 30, to the second input of which a modulating code M ₁ (t) is supplied from the second output of the modulating code generator 24. Since there is a strong correlation between the voltage U _n1 (t) and the modulating code M ₁ (t), a voltage is generated at the output of the correlator 30 that exceeds the threshold voltage ν _pores in the threshold block 31. The threshold level ν _pores in the threshold block 31 is selected such that only the maximum output voltage of the correlator 30 can exceed it. When the threshold level ν of _pores is exceeded, a constant voltage is generated in the threshold unit 31, which is supplied to the control input of the key 34 and opens it. In the initial state, the key 34 is always closed. In this case, the supply voltage through the public key 34, the closed ignition key 33 and the closed contacts 36.1 of the switch 36 is supplied to the relay coil 35. The latter is triggered. This condition corresponds to the case when an attacker tries to steal a vehicle. When the relay 35 is activated, contacts 35.1 are closed, duplicating the supply voltage to the transceiver unit 10, contacts 35.2 are opened, the engine is turned off, contacts 35.3 are closed, including an audible warning device 38 and signal (position) lamps 44-47, contacts 35.4 are closed, including an electronic lock, which locks the doors of the vehicle. This fact does not allow the attacker to quickly leave the cabin of the stolen vehicle.

The alarm signal emitted by control room 14 and vehicle 2 is simultaneously received by capture groups (mobile vehicles, posts and individual police officers and traffic police), which, using light and sound alarms, take various measures to detain intruders and a stolen vehicle.

These actions provide an increase in the effectiveness of protecting the vehicle from theft and theft. This is achieved by using an alarm phase-shifted signal that carries information about the fact of unauthorized impact on the vehicle, about the number, make, color of the hijacked vehicle and its location, and a control signal that turns off the engine, turns on the sound and light alarms, and also locks the doors . Moreover, the included sound and light alarms are signs of the detection of a stolen vehicle, and the turned off engine and locked doors ensure the detention of the vehicle and intruders.

Thus, the proposed device to protect the vehicle from theft and theft in comparison with the prototype and other technical solutions of a similar purpose provides increased reliability and efficiency of monitoring the movement of the vehicle and the cargo on it, as well as by reducing the time to assist the driver in the event of various emergency situations.

Significant differences of the claimed device in comparison with known analogues are:

1. Continuous (periodic) monitoring of the presence of containers on the vehicle with an indication of the status both on the vehicle itself and at the control center, which eliminates the possibility of theft of containers from the vehicle

2. Continuous monitoring of the state of the container’s burglar alarm, prompt communication to the vehicle’s onboard equipment and to the control room about all cases of opening containers, which allows the driver to immediately receive information about the state of the cargo, and at the control room immediately have information about all facts of opening containers with indication of the operators who turned on and off the alarm.

3. Prompt informing the dispatcher about the time and place of opening the containers, which allows law enforcement officials to intervene promptly if necessary.

4. The storage of information on all facts of opening containers on the route of the vehicle allows the loss of goods to determine the circle of persons suspected of theft.

5. The use of secret passwords of the container and the operator during authorized operations with goods increases their security by quickly detecting people trying to open the container, but who own only one password.

6. Periodic and prompt (with unauthorized opening of containers) the inclusion of an alarm allows you to solve the problem with the power supply of containers during long-term transportation.

7. Information from the container burglar alarm slightly loads the information transfer path between the vehicle’s onboard equipment and the control room (only in emergency situations), which allows the use of the control room to control many vehicles with a large number of containers.

The proposed device provides protection not only for passenger vehicles from theft and theft, but also for vehicles with cargo. This circumstance extends the functionality of the device to protect the vehicle from theft and theft.
