Analysis and Improvement of Receiving Route Coding Circuit for Station Connected with Short Section

列车在运行过程中接收到错误电码化信息,存在巨大的安全隐患。结合电码化电路原理,从设计方案出发,按实际线路情况,对短区间车站接车电码化电路进行分析和研究,提出一种解决车载信号出现跳变、错码、掉码等问题的方法,通过修改站间联系电路从根本上解决了现场问题,避免潜在风险。通过深度分析车载信号突变的原因,阐述站间联系电路的修改思路,为后续工程设计和应急处置提供参考。

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.
