Abstract

FIELD: transport.

SUBSTANCE: proposed system operates in preset frequency range and incorporates automotive transport motion detection and control hardware mounted at the railroad crossing area. The previously mentioned hardware comprises a stationary module with a transmitter sending radio signals to the mobile module receiver aerials arranged on the vehicles. The said transmitter is mounted on the light signal. The system stationary module can emit the "cross-over inhibited" signal to mobile modules and switch the light signal over to the red. It also compares the data received from the stationary module with the data stored in the mobile module memory when the vehicle approaches the system operating range. The system cuts in sound and light signaling in the driver's cab and locks the vehicle engine to stop it in case the vehicle goes on running.

Description

The invention relates to safety equipment in railway transport, in particular to means for ensuring safety on railway tracks in the area of crossings.

It is known that the railway crossing is one of the most dangerous sections, and the collision of vehicles (ATS) with the train is one of the most serious types of road accidents, accompanied by numerous casualties. Meanwhile, accidents at railway crossings occur regularly and most often through the fault of drivers of vehicles. According to ITAR-TASS, there were 55 accidents on the Moscow highway in 2003, all due to the driver’s fault, in which 13 people died and 31 were injured. Collisions are caused by the lack of discipline of drivers who tried to drive in front of an approaching train, ignoring the prohibition signal of a traffic light, or caused by a malfunction of vehicles.

Modern microprocessor systems allow not only to detect automatic telephone exchanges, but also to identify them by registration marks. This is due to the fact that there is an automatic registration in memory of the image of objects that appeared after lowering the barriers in the danger zone of the railway crossing. Registered images can then be analyzed by security officials to identify violators of the rules of the road, and in the event of an accident - evidence in court.

A disadvantage of existing video processor systems is the inability to warn traffic participants about approaching each other and take effective measures to prevent a collision [1].

This drawback is eliminated in the Japanese patent [2], the device for which contains 2 video cameras mounted on both sides of the railway track. In the area where one of the cameras is located, a loudspeaker is located. Video cameras and a loudspeaker are connected to a video processor device comprising a multichannel motion detector configured to automatically detect moving objects in a railway crossing area. If an intruder is detected, the decisive device that is part of the video processor device sends a command to turn on the voice message generation unit, the output of which is connected to the loudspeaker. If the intruder did not respond to the voice message and continues to be in the danger zone of the railway crossing, then the decisive device forms a decision on the emergency stop of the train. Wirelessly, this command is transmitted to a moving train and is used to emergency stop the train - manually or automatically. The described system is focused on the complete automation of identifying accident violators and responding to a dangerous situation. Such a system facilitates the work of the driver, but there is a danger of false alarms and non-detection of dangerous situations.

From the above examples, the problem of such a solution of the problem follows so that the driver can quickly respond to the current dangerous situation. The prototype of the claimed invention is a "System for the prevention of accidents on the railway track", which includes a video processor subsystem for processing and recording images, an alarm block installed in the train equipment (blocking the movement of the train, sound siren), while the screen of the video monitor located in the cab the driver, is in his field of vision, and the equipment for blocking the movement of the train is made controlled by the driver. The solution under consideration allows more effectively to prevent accidents at a railway crossing, since the driver has the ability to promptly and quickly respond to a dangerous situation [3].

The task of preventing accidents is proposed to be solved in a completely different way - by stopping the car, and not the locomotive.

There are systems that allow you to act on a vehicle by stopping it by blocking the engine.

A similar radio frequency identification system is described in the patent "Anti-theft system for vehicles according to patent RU No. 2295465 [4].

The described analogue consists of a transceiver-reader located at the user and a transceiver-tag installed in the functional organs of the vehicle, and the tag and reader are configured to conduct a dynamic identification dialogue with each other, which consists in transmitting signal packets from the reader to the tag randomly varying numbers from parcel to parcel, receiving a tag of specified parcels, non-linear transformation of random numbers in accordance with the non-linear algorithm embedded in it ohm and reverse transmission of the converted random numbers to the reader, as well as a parallel identity non-linear conversion of random numbers by the reader, comparing the results of the identity non-linear conversion with the non-linearly converted random numbers received from the tag and sending the central control unit of the anti-theft system messages about the identification made.

The proposed task of preventing accidents at a railway crossing is proposed to be solved in a completely different way - by stopping the car, not the locomotive, which is a simpler solution to the problem, since it is much easier to stop the car than the locomotive.

The proposed accident prevention and driver alert system at the railway crossing consists of a stationary module and a mobile module. The stationary module consists of a transceiver and an antenna mounted on a traffic light, the mobile module consists of a transceiver and an antenna located on a vehicle. The mobile module is connected to the sound and light alarm unit included in the system, the engine control unit of the car to block movement. The proposed system differs from the analogue in that the stationary module is switched on synchronously with the red traffic light, and the mobile transceiver receives this signal and includes sound and light alarm units, and if the driver has not taken measures to stop the car, it blocks the car engine. Thus, the task of increasing the effectiveness of accident prevention is significantly increased compared to previously proposed systems.

The proposed driver identification and warning system for preventing accidents at a railway crossing, comprising vehicle detection and monitoring equipment located in the crossing area, comprising a transceiver emitting a radio signal to a receiving antenna of another transceiver located on the vehicle, characterized in that one of the transceivers located at the traffic light (stationary module), which turns on synchronously with the red signal of the traffic light, while The transmitter is powered up either directly from the traffic light or has its own power supply. The signal transmitted to car transmitters located in the car can be either analog or digital. The probability of the proposed system coming out of working condition is very small, because if the traffic light turns out to be inoperative, it will be repaired in a minimally short period of time. The invention uses existing engine control units and significantly increases the efficiency of preventing accidents at a railway crossing.

The system is schematically depicted in the drawing and consists of a traffic light 1, a stationary transceiver 2, an antenna 3, a mobile transceiver 4, a sound alarm unit 5, a light signaling unit 6, a device for blocking an automobile engine 7 (FIG. 1).

The proposed system works as follows. When the red signal of the traffic light is turned on, the stationary module starts to emit a “travel denial” signal to mobile transceivers - when a vehicle appears in the coverage area of the car system, the data received from the stationary module is compared with the data stored in the memory of the mobile transceiver, and if they match, it turns on sound and light alarm, and if the car continues to move after turning on the alarm for 3 seconds, information about this is sent to the device via the information channel The engine is locked and it stops.

Further movement is possible only when the red traffic light changes to green.

The technical result of the claimed invention consists in increasing the efficiency of collision avoidance at a railway crossing, which is expressed in the fact that of two disparate in mass and speed of the participants in the movement - train and car - the system issues a command to stop the car, which has kinetic energy many times less than a train, and which is much easier to stop than a train.

The technical result is also expressed in the fact that the proposed design is easier to manufacture, since it does not require such complex systems as the video processor monitoring and installation system described in the prototype, and in addition, it allows the use of existing engine control units and anti-theft elements in an automobile module devices.
