武汉地铁16号线LCU旁路后车辆异常限速问题的分析

Analysis of Abnormal Speed Limit Problem of Vehicles after LCU Bypass of Wuhan Metro Line 16

摘要: 武汉地铁16号线牵引封锁有两种判断逻辑，当牵引系统或网络系统采集到所有制动不缓解信号后，均会触发牵引封锁保护，本项目所有制动缓解信号通过LCU来输出，本文主要分析车辆LCU旁路后异常限速的原因并给出解决方案。

Abstract: There are two kinds of judgment logic for traction blocking of Wuhan Metro Line 16. When the traction system or network system collects all braking non release signals, it will trigger traction blocking protection, all braking release signals of the project are output through LCU, this paper mainly analyzes the causes of abnormal speed limit after vehicle LCU bypass and gives solutions.
