Description

The invention relates to techniques for positioning and tracking vehicles and can be used as a system of operational control in railway transport.

A known system for identifying rolling stock units located in the coverage area of the interrogating device, comprising a transmitter with a frequency divider and a receiver connected to the transmitting and receiving antennas, a phase demodulator connected to the receiver and the data processing unit, and mounted on the vehicle receiving antenna associated with the rectifier, frequency divider and converter of the received radio signal into a code signal connected via a phase modulator to the transmitting antenna (application of Germany No. 1813319, CL VL 25/02, 1980).

This system has insufficient reliability and requires significant material costs.

Known is the Palma automatic rolling stock identification system, which contains passive radio frequency identification sensors - CBD - code on-board sensors mounted on cars, identification data readers with antennas, stationary located along the track, for example, at the entrance and exit from the station, wheelset sensors, connected to the reader and mounted on the rails, generating a signal to turn on the reader when the composition approaches it. During the passage of the composition, information from the on-board sensors is generated in the reader in a data packet and transmitted via a wired or fiber-optic communication line to the station dispatcher console (V.V. Belov, M.M. Gershenzon, D.S. Kotletsov Implementation of an automatic identification system for rolling stock on Russian Railways // World Railways, 2003, No. 7).

The disadvantages of the system are as follows. A reader with an antenna and wheel pair sensors are permanently located in the rolling stock control point, while the density of the control network is directly proportional to the number of points mentioned and does not provide carriers with the need for accurate information about the location of the cargo at a particular point in time, due to the significant sparseness of the control points, for example , on the hauls between stations. The creation of a network of stationary points necessary for effective control of the density leads to a large volume of construction and installation works.

The objective of the invention is the development of a dynamic automatic identification system of rolling stock, providing the creation of a network for monitoring rolling stock of high density without the construction of additional control points, which significantly reduces material costs while ensuring the necessary performance.

To this end, in a system for the automatic identification of rolling stock on railways containing passive identification sensors mounted on wagons, as well as identification readers with antennas, according to the invention, identification readers with antennas are mounted on locomotives of railway trains, and oncoming train detection means are connected to the readers containing receivers of satellite navigation signals, and the readers on the data and control buses are connected to modems Frova connection.

Creating a dynamic system for identifying rolling stock by placing the specified equipment complex on locomotives allows you to increase the number of points for obtaining operational information on the positioning of rolling stock, for example, on hauls between stations, without significant costs to create an information network whose density on transit routes is much higher than traditional, because it is determined not by the number of readers, but by traffic intensity and increases with the growth of cargo flow, which allows operational information about the loads on stages, where the creation of stationary checkpoints difficult or impossible for technical reasons.

The invention is illustrated in the drawing, which shows a block diagram of the proposed system.

The system for automatic identification of rolling stock on railways contains an antenna 2, the transceiver path of which is connected to a reader 1, connected via a data bus with means of detecting an oncoming train 3, made in the form of a computerized transceiver of low power, and a receiver of satellite navigation signals 4, while the output of the means 3 supplies power to the reader 1 and the digital communication modem 5, connected via data and control buses, located on the locomotive 7 and passive radio frequency identification 6 sensors mounted on wagons.

The automatic identification system of rolling stock works as follows.

The oncoming train 3 detection means during the movement of the locomotive 7 generates and broadcasts a composition recognition code containing its current coordinates. When the trains approach each other, the means 3 of both trains that have entered the radio exchange determine the moment of the synchronous switching on of the readers 1. Using antennas 2, the sensors 6 are irradiated and the information read out from them, which in the reader 1 is formed into a message, combined with the current coordinate and transit time of each of the sensors 6 oncoming train. This message is sent to the digital communication modem 5 and transmitted using it to the remote Internet server of the railway dispatch system.

Thus, the proposed system enables cargo owners to determine the current location of goods with high accuracy, and rail services to quickly track dangerous and valuable goods with accurate information about the place and time of an emergency or emergency. The application of the described system is especially relevant in the framework of the transit corridors being created, such as Western Europe and Western China, since the damage from the dispatch error and the emergency situation with the predicted traffic density is unreasonably large. The proposed system, due to mobility, is more universal than the traditional one, the used wireless data channel and its organization will allow it to be included in the country's intellectual transport system without any modifications.
