Description

The invention relates to electronic instrumentation, in particular to digital tachographs, and can be used for installation in vehicles for the continuous and operational measurement, display, monitoring, storage and transmission of vehicle motion parameters, i.e., for continuous recording of the distance traveled, time and speed of movement, working hours and rest of drivers, route and time of movement, as well as for prompt notification of dispatch points about accidents that have occurred with vehicles Twomey. For recording, storage and transfer of information, electronic cards and digital memory of the control device itself are used. To transmit information to control centers, blocks for receiving and transmitting data via satellite and radio data channels GLONASS / GSM and GSM / GPRS are used.

Digital tachographs are known from the prior art, including functions such as indication, control, storage, transmission of information about the movement and location of a vehicle and time intervals of work and rest periods of drivers, for example, a digital tachograph according to RF patent No. 1155533 (RU), consisting of a housing, control buttons, a microprocessor unit with non-volatile memory, a power supply unit, a GLONASS / GPS satellite signal reception unit, with an antenna, a GSM / GPRS radio signal reception and transmission unit with an antenna, a scale forming unit time, interface unit, printing device - thermal printer, card reader unit with card readers, control unit and indicator - screen. Using this digital tachograph allows you to continuously display, register, store, print the speed and time of movement of the vehicle, mileage, periods of work and rest of drivers, to obtain information about the location and route through the GLONASS / GPS satellite navigation system and transmit all this information to control rooms points on the GSM / GPRS radio channels.

The closest technical solution to the proposed digital tachograph is a digital tachograph according to RF patent No. 139522 (RU), consisting of a housing, a control unit with buttons, a printing device, card readers of a card reader unit, a non-volatile memory unit, a microprocessor unit, an interface unit, a satellite signal receiver unit GLONASS / GSM radio navigation systems, GSM / GPRS radio channel radio signal transmission unit, satellite navigation antennas, radio channel antenna, screen, timeline forming unit, unit and the power supply of at least one shock sensor, which can be combined with a tilt sensor (position, roll). In this case, shock sensors and tilt sensors (position, roll) can be placed inside the housing, on one side of the housing or outside the housing.

The known digital tachograph in terms of operational capabilities has certain disadvantages, since not every collision of a vehicle with any obstacle requires an emergency arrival of operational rescue services, since these collisions can be insignificant or false, and its design does not automatically determine the degree of deformation cab or passenger compartment of a motor vehicle, i.e. the degree of change in their normal volume, and bring this information to control centers and operational rescue services.

The invention is based on the task of expanding the capabilities of digital tachographs by creating such a digital tachograph, which made it possible to automatically determine the degree of deformation of the cab or passenger compartment of a vehicle, i.e. the degree of change in their normal volume, and bring this information to control centers and operational rescue services. Obtaining such information will help operational rescue services to eliminate false operational trips associated with minor vehicle accidents and malfunctions of shock and tilt sensors (roll).

In this case, the technical result is the implementation of this purpose.

The achievement of the above technical result is achieved by expanding the technical capabilities of the digital tachograph due to the ability to automatically determine the degree of deformation of the cab or passenger compartment of an automobile vehicle by determining the degree of change in their volume, and bring this information to control centers and operational rescue services.

The technical result is achieved by the fact that a digital tachograph consisting of a housing, a control unit with buttons, a printing device, card readers of a card reader unit, a non-volatile memory unit, a microprocessor unit, an interface unit, a receiver unit for GLONASS / GSM satellite navigation systems, a radio channel for transmitting radio signals GSM / GPRS, satellite navigation antennas, radio channel antennas, screen, timeline forming unit, power supply unit, at least one shock sensor, which m Jet be combined with tow (provisions roll) is further provided with at least one sensor, change in volume, from which data are recorded and stored in the microprocessor unit and the nonvolatile memory are transmitted via the radio transmission unit to the control point. The volume change sensor can have any emitter, including ultrasonic or electromagnetic. At the same time, the principle and method of measuring volume in real time by a volume change sensor does not matter. It is important that these measurements are reliable and operational. Therefore, the volume change sensor can be structurally designed so as to have two or more different types of emitters. A digital tachograph equipped with a volume change sensor, before starting to use it, is set to the normal volume of the cabin or cabin in which it is installed.

Volume change sensors can be placed outside the digital tachograph and exchange information with the digital tachograph by electrical signals via connecting wires or radio signals, for example, such as WiFi or Bluetooth.

The proposed digital tachograph differs from the prototype in that it includes at least one volume change sensor to determine the degree of volume change associated with deformation of the cab or passenger compartment of the car or bus.

The essence of the claimed invention is illustrated in Figure 1, Figure 2, Figure 3 and Figure 4.

Figure 1 shows a digital tachograph with a volume sensor.

Figure 2 shows a digital tachograph with a volume change sensor located outside the digital tachograph, which is connected to the control device by connecting wires.

Figure 3 shows a digital tachograph with a volume change sensor located outside the digital tachograph, which communicates with the digital tachograph by radio signals.

Figure 4 shows a block diagram of a digital tachograph, showing its main blocks and structural relationships between them.

The digital tachograph consists of a housing 1, a control unit with buttons 2, a printing device 3, card readers of a card reader unit 4, a non-volatile memory unit 5, a microprocessor unit 6, an interface unit 7, a signal receiver unit of GLONASS / GSM 8 satellite radio navigation systems, a radio signal transmission unit GSM / GPRS 9 radio channel, satellite navigation antennas 10, radio channel 11 antennas, screen 12, timeline forming unit 13, power supply unit 14, at least one shock sensor 15, which can be combined with a sensor ohm tilt (position, roll) 16, as well as from at least one volume change sensor 17. Moreover, shock sensors 15, tilt sensors 16 and volume change sensors 17 can be placed inside the housing 1, on one side of the housing 1 or outside the housing 1. When the shock sensors 15, tilt sensors (position, roll) 16 and volume change sensors 17 are located outside the housing 1 of the control device, they are connected to it by wires 18 through connector 19 or equipped with radio transmission and reception units 20, for example, such as Wi-Fi / Bluetooth, with a battery, for example , Battery or accumulator.

The screen 12 is made in the form of a graphic display, which provides the drawing on the screen of the icons provided in the tachographic equipment. As a printing device 3 for outputting paper reports on operating modes, errors and irregularities, a thermal printer is also used, which also has a graphics output mode.

The operation of the digital tachograph is as follows.

The unit for forming the time scale 13 makes an accurate countdown, which continues during the storage of the digital tachograph with the power off, and transmits this information to the microprocessor unit 6. The interface unit 7 receives signals from the motion sensor in the form of speed pulses, and also provides its electrical power . Since the interface block 7 implements the possibility of exchanging information in CAN, RS232, ISO9141 standards through the corresponding ports, it connects the digital tachograph to the vehicle’s on-board CAN network (CAN interface), as well as connects to external devices, for example, personal computer (RS232 interface) and diagnostic equipment (ISO9141 interface). The interface unit 7 transmits all the information received in the form of pulsed digital signals to the microprocessor unit 6. In addition, the local time scale data (current time and date), as well as navigation data from unit 8, are received from the unit 13 to the microprocessor unit 6.

The identification of drivers and other persons involved in the operation of the vehicle’s digital tachograph is carried out by smart card reader 4. These data also come in microprocessor unit 6.

The microprocessor unit 6, including using an analog-to-digital converter of the interface unit 7, which digitizes analog signals, processes the input signals and data and forms, stores and stores them in module 5 and smart cards through unit 4, as well as transmits through the block 9 and antenna 11 output information about the parameters characterizing the state of the vehicle and its movement on the route, the coordinates of the route, the current time and date, as well as data about the drivers involved in driving redstvom. In addition, the microprocessor unit 6 also generates output pulse signals arriving at the port of the interface unit 7, the first group of which characterizes the current speed of the vehicle, and the second - the distance traveled. Pulse output signals are intended for use as input signals for an electronic vehicle speedometer.

In normal mode, i.e. when the vehicle is moving on the road or stands still, the microprocessor unit 6 through the interface unit 7 receives speed information from the speed sensor installed in the vehicle’s gearbox, the position on the terrain of the vehicle from the antenna 10 and the GLONASS / GSM satellite navigation unit 8, on the position in the vehicle space from the tilt (position) sensor 16. All this information received and processed by microprocessor unit 6 is stored in non-volatile amyati 5 of the digital tachograph cards and drivers and simultaneously transmitted to one or more master stations transmit radio block 9 GSM / GPRS radio channel through the radio antenna 11.

In the event that an accident occurs with the vehicle, for example, if the vehicle hits an obstacle, the shock sensor 15 or several shock sensors 15 transmits (s) the signal (s) via the interface unit 7 to the microprocessor unit 6 of the digital tachograph that a vehicle collided with some kind of obstacle, and information about it is recorded and stored in the non-volatile memory 5 of the digital tachograph itself and in the driver’s cards, and also automatically transmitted by the delivery of radio signals 9 of the GSM / GPRS radio channel through the antenna of radio channel 11 to one or more control centers and emergency operations with an indication of the place for the arrival of rescue services at the scene of the accident. If, as a result of a collision with an obstacle, the vehicle rolls over or capsizes, the microprocessor unit 6 of the digital tachograph, having received the corresponding signal from the tilt sensor 16 through the interface unit 7, automatically transmits through the GSM / GPRS 9 radio channel unit and antenna 11 to the control centers and emergency operational services that the vehicle not only collided with some kind of obstacle, but also turned over (capsized).

In order to avoid false reporting of accidents with a vehicle requiring the prompt arrival of emergency services, the microprocessor unit 6, before transmitting this information to control centers and operational rescue services, not only performs, according to a certain algorithm, an analysis of the impact force from the signal received from the shock sensor 15, and the angle of inclination determined between the action of gravity and the position in the vehicle space according to the signals received from the inclination sensor 16, but the analyzer with the help of the software embedded in it, electric signals coming from the volume change sensor 17 to receive signals from the shock sensor 15 and tilt sensor 16, i.e., when it is set up with a normal interior volume, and the incoming signals from the volume change sensor 17 after receiving a signal from the shock sensors 15 and / or the tilt sensor 16 about the collision of the vehicle with an obstacle and / or its capsizing. All signals from all sensors enter the microprocessor unit 6 through an analog-to-digital converter of the interface unit 7, which converts the analog signals of these sensors into digital form.

Microprocessor unit 6 analyzes the incoming signals according to the algorithm embedded in it using the embedded software. When the microprocessor unit 6 determines the change in the cabin or passenger compartment volume, for example, by more than 10%, it gives a command to the GSM / GPRS 9 radio channel unit to transmit not only an accident with the vehicle through the antenna 11, but is there, i.e. . whether there was a deformation of his cabin or cabin and the degree of this deformation. Information about the deformation of the cab or passenger compartment of the vehicle allows dispatchers and emergency services to make predictions about the severity of a vehicle accident.

To expand the functionality, volume change sensors 17 can be placed outside the housing 1 of the digital tachograph. Moreover, their relationship with the microprocessor unit 6 of the digital tachograph can be carried out through the interface unit 7 both via wires 18 and radio signals, for example, Wi-Fi or Bluetooth, using the transmit-receive block of radio pulses 20, which has its own battery: battery or miniature battery.

All information recorded and stored in memory 5, including the time, place and cause of the accident (accident) of the vehicle, if necessary, can be printed using a printing device 3.

Thus, a digital tachograph with the ability to notify of vehicle accidents, among other things, fully solves the tasks of not only the quick automatic notification of control centers and emergency services about accidents with a vehicle, but also informs them of the degree of damage and deformation of the cabin or vehicle interior. Obtaining such information will help operational rescue services to eliminate false operational trips associated with minor vehicle accidents and malfunctions of shock and tilt sensors (roll).

The possibility of carrying out the invention with the implementation of the task is confirmed by the known means and methods. Thus, the possibility of carrying out the invention is confirmed.
