摘要
调谐区纳入列控中心控制检查后,由于邻站边界区段轨道电路传递给本站的TCC的小轨状态存在延迟,在本站GJ吸起后,TCC已判为区段逻辑状态空闲后再次收到邻站传递的边界小轨占用信息,导致本站边界区段出现闪红光带,影响信号设备可靠运用。针对上述问题进行分析,并提出相应改进方案及措施。
After the tuning zone was included in the control inspection of the Train Control Center(TCC),a delay occurred in the transmission of the status of a small track circuit from the track circuit of the boundary section of the neighboring station to the TCC of the current station.As a result,after relay GJ was energized at the current station,the TCC once again received information from the neighboring station indicating that the small track circuit of the boundary section was occupied,even though the TCC had determined that the logic state of the section was clear.This inconsistency resulted in a fl ashing red-light strap in the boundary section of the current station,which aff ected the reliable operation of the signal equipment.This article analyzes the aforementioned issues and proposes corresponding improvement plans and measures.
