接近区段机车信号误码问题分析及改进方案

Analysis and Solution of Locomotive Signal Error Code in Approach Section

针对计算机联锁驱动相关继电器存在时延,当办理正向接车进路后接着办理正向发车进路时,第三接近区段机车信号收到突变LU码,出现“灯码不一致”的问题,对编码电路详细分析,研究提出两种编码电路改进方案,较好地解决了“突变码”问题,提高了设备运用质量。

Based In view of the time delay of the related relay driven by the computer interlocking,when the forward receiving route is set and then the forward departure route is set,the cab signal of the third approach section receives the sudden change LU code,which causes the problem of“inconsistent light code”.The coding circuit is analyzed in detail,and two improvement schemes of the coding circuit are proposed,which better solve the above“sudden change code”problem and improve the quality of equipment use.
