摘　　要：在轨道区段中存在一种室外有分割而联锁按一个区段处理的特殊情况,会造成集中监测系统因采集轨道电路开关量和模拟量不匹配而发生误报警的问题。归纳总结了出现此类区段的3种典型场景,分析了出现误报警的原因,并提出了对应解决措施,对今后其他类似情况具有参考意义。In the design of centralized signaling monitoring system, there is a special case in which the track section is treated as two parts in the outdoor signaling system while regarded as one section in the indoor interlocking. In such a condition, normal design would lead to false alarm because the switching values from track circuit does not match the analog quantities. Therefore, three typical cases involving this kind of track section are summarized and the reasons leading to false alarm are analyzed respectively. Finally, corresponding solutions to avoid false alarm are proposed, providing reference for similar circumstances later.
