特殊场景下动车组误接收电码化信息问题探讨

Discussion on the Problem of EMU Failing to Receive Correct Coding Information in Particular Situation

特殊的车站电码化场景中动车组列车存在错误接收电码化信息的问题,严重时会导致ATP制动停车事故。从机车信号信息传输原理出发,结合实际案例,从电码化设计方案、动车组自身特点等角度进行分析和研究,得出主要原因是电码化方案设计有缺陷、动车组空载自重轻、列车运行速度慢等。针对各种原因,分别提出相应的解决措施,最后着重从改进电码化设计方案的角度给出解决方案,并提出不同方案的选用建议。

The problems of EMU receiving incorrectly the coding information exist in particular station coding condition,which,if serious,may cause ATP parking accident. Based on the analysis of the principle of cab signal information transmission and practical cases in terms of the design of coding and the characteristics of EMU,it is conclude that the main failure causes are the design defects,the light dead load of empty EMU and slow running speed of the train. In view of the various reasons,corresponding measures are proposed,solutions are recommended to improve coding design scheme and advices are offered for scheme selection.
