Train tracking method based on information redundancy

Abstract

The invention provides a train tracking method based on information redundancy. According to the technical scheme, under a normal communication state circumstance, a train is directly tracked through a train tracking system according to real-time positions sent by a VOBC preferentially, and VOBC information is verified through a ZC and interlocking equipment; under the condition that a communication failure happens to the VOBC, the train is tracked through track position information sent by ZC equipment, and meanwhile, verification is carried out according to interlocking equipment information; when communication failures happen to the VOBC and the ZC at the same time, the position of the train is tracked in a backup mode of the interlocking equipment. Three tracking modes are automatically switched over according to the communication states of the train tracking system and an external system to complete continuous tracking of the position of the train, precision of data in the tracking process of the train is excellently guaranteed because of adding of redundant information, and therefore the train can be tracked in a real-time, accurate and continuous mode through the method, and timeliness and accuracy of decision-making of dispatchers are improved to a great extent.

Description

technical field [0001] The invention relates to the field of rail traffic signal control, in particular to a method for tracking trains in a train monitoring system. Background technique [0002] The dispatchers of the train track traffic monitoring center can dispatch the trains in real time by mastering the train location information to ensure the orderly operation of the trains. The mastered train location information directly affects the accuracy and timeliness of the dispatcher's decision-making. [0003] As an important part of the automatic train monitoring system, train tracking is the guarantee and basis for the modernization and intelligence of urban rail transit operation management and command. Traditional train tracking systems usually receive information sent by Vehicle On Board Controller (VOBC) As the current train position information, complete the real-time tracking of the train. [0004] However, when the communication between VOBC and the train tracking ...

AI Technical Summary

Problems solved by technology

[0004] However, when the communication between VOBC and the train tracking system is interrupted, the tracking system cannot know the real-time location information of the train, resulting in the "lost" of the train, the train tracking system cannot complete the tracking of the train, and the dispatcher in the monitoring center cannot grasp the train The location information cannot complete the real-time dispatch of trains, and in severe cases, it will lead to accidents such as train collisions and rear-end collisions.
