Abstract: The train receives the error coding information in the course of running, which has a huge hidden danger. Combined with the principle of the coding circuit, according to the design scheme and actual line conditions, this paper analyzes and studies the coding circuit of the station connected with short section, and puts forward a method to solve the problems of onboard signal jumping, error code, code dropping, etc. By modifying the liaison circuit between stations, the problems on site are fundamentally solved and the potential risks are avoided. Through in-depth analysis of the cause of onboard signal mutation, the idea of modifying the liaison circuit between stations is expounded to provide reference and guidance for the subsequent engineering design and emergency disposal.
