Discussion on Improving Safety of Station Tracks Equipped with Integrated Track Circuits of High-speed Railways
摘要
Abstract
At present,the ZPW-2000 integrated track circuits with the same standard as those used in the sections are widely used in China's high-speed railway stations,and the platform tracks in some stations adopt one-section track circuits.When the train is received at the station,the sending end of the track circuit of the platform track will face the train and send codes to provide trackside information for the train.If the train comes to a complete stop at the station and changes its direction by activating the cab on the intended end,when the starting signal is not at clear,the train may mistakenly receive the information sent by the track circuit of the adjacent line,and the train will depart from the station incorrectly,resulting in safety problems.In this paper,the method of adding an external relay circuit is proposed,and the timing of the train entering and leaving the platform track is determined by the circuit logic,and the concrete measure for applying train tail complementary code is provided,so that the double-end code sending can be realized after the train enters the track to solve the aforementioned problems.This solution only adds a small number of relays indoors,has no outdoor workload,does not need to change the train control software,and can be adapted to suit individual platform tracks of the station.The adaptation process is easy to implement and has minimal impact on transportation.This scheme can provide reference for the solution of safety protection enhancement for platform tracks equipped with integrated track circuits in high-speed railway stations.关键词
