列控中心驱采不一致分析及改进方案

杭深线厦深段开通初期,经常出现列控中心驱采不一致报警,影响信号设备可靠运用。本文针对LKD2-HS型列控中心驱采不一致的报警.对列控中心驱采过程和报警代码进行分析,明确采集不良信息点的位置;并针对点灯切换时继电器前后接点产生“拉弧”,及列控采集电路可靠性不高问题进行了分析,提出了相应改进方案及措施。

Analysis and Improvement Scheme of Driving and Acquisition Inconsistency in TCC

At the early stage of the opening of Xiamen-Shenzhen segment of Hangzhou-Shenzhen line,the train control center frequently sends off the alarm of inconsistent driving and acquisition,which affects the reliable operation of signal equipment.To cope with driving and acquisition inconsistency alarm in LKD2-HS type train control center,the driving and acquisition process as well as alarm codes of the train control center are analyzed to seek out the location of bad data collection point.Furthermore,the discharge of the front and rear contacts of the relay during the lighting switching and the low reliability of the train control data acquisition circuit are analyzed and the corresponding improvement scheme and measures are put forward.
