列控车载设备“无码”问题研究

Research on No Code Fault of On-board Equipment of Train Control System

在列控系统运用中,车载设备"无码"是一种常见故障,深入分析无码原因并研究解决方案,对提高列控车载设备的可用性和安全性具有重要意义。本文给出无码的基本概念和分类,分析不同类型无码的原因,梳理现行规范中有关无码的相关条款,最后通过典型实例,从车载角度解读无码的处理原则。

In the operation of the train control system, no code is a common fault occurring to its on-board equipment. So, it is significant to deeply analyze the cause of no code faults and figure out a solution to the fault, thus improving the availability and safety of the on-board train control equipment. The concept and classification of no code faults is explained and the cause of each mode of no code fault is analyzed. Besides, relevant provisions of the specifications on no code fault are sorted out. Finally, the principle of handling no code faults from the perspective of on-board equipment is explained by several typical examples.
