Abstract: In the process of transformation of Taiyuan North Railway Station terminal, there is no turnout section on the train receiving route, and the train directly enters the track after crossing the protective route signal. When the protective signal mutates for some reason, the train enters the track after overrunning the protective signal and receives the wrong low frequency signal. This paper mainly studies the reason why the train mistakenly receives low frequency signal after overrunning. By discussing the functions of the conventional circuit and the common simplified circuit of the conventional station, this paper analyzes the work flow of the station after overrunning, and summarizes the reasons for the failure to send the forbidden code and the failure to cut off the code channel. In view of the reasons, this paper puts forward two feasible ideas of optimizing JMJ relay's energized circuit and optimizing station type to solve the problem, and the two ideas are respectively further designed for verification. According to the actual field situation, the optimization of JMJ relay energized circuit method is recommended for field implementation.
