An RFID-based auxiliary control method for rail trains

Abstract

An RFID-based rail train auxiliary control method that can be quickly constructed, low-cost and easy to maintain, comprising arranging transponders along the track and installing on-board equipment on the train, the transponder being a readable and writable RFID with built-in location information Electronic tags, on-board equipment including RFID readers and operation control systems; when each train passes the RFID electronic tags, the RFID reader on the train writes its own train information to the RFID electronic tags, and reads the storage in the RFID electronic tags. position information and the train information written by the preceding train in the same direction when it passes the RFID electronic tag; the operation control system determines the position information of the train according to the information stored in the RFID electronic tag read by the RFID reader, and determines the position information of the train. The relative position and tracking relationship between them are logically judged, and the operation of the train is controlled according to the judgment result. This control method can meet the requirements of today's high traffic density and high safety standards.

Description

technical field [0001] The invention relates to an RFID-based auxiliary control method for rail trains, belonging to the field of train control. Background technique [0002] Railway transportation is the most common and extensive mode of transportation in China. With the continuous progress and development of China's railways, the speed of railways is getting faster and faster, and the traffic density is getting higher and higher. Correspondingly, the importance of railway safety is also increasing. Just getting higher and higher. Most of the railway accidents in recent years are caused by scheduling and human errors, so the reliability of equipment should be further improved, the automatic safety of equipment should be improved, and the possibility of accidents should be reduced. [0003] The current train operation control systems CTCS2 and CTCS3 of China Railway use the track circuit to locate the position of the train, and cannot get rid of the dependence on the physic...

Problems solved by technology

However, if the following train mistakenly receives the signal of the preceding train that is not the preceding train immediately before, and controls the traveling speed of the following train according to the train position of the train, there is a problem of exceeding the allowable range and approaching the original signal. Moreover, this method is still limited by communication speed and greatly limited by environmental factors, so it is difficult to meet the requirements of high traffic density
