摘　　要：场联信号是车站2个场间安全高效行车作业的重要保证。将场联继电电路升级为电子执行模块后,应确保两场间敌对照查、邻场信号状态、接近预告等联锁信息的可靠传输。在场联信号设备升级工程分阶段实施过程中,存在已替换的电子执行模块与其余既有场联继电电路结合不匹配问题,导致场间作业过程中,因某些照查继电器短时落下造成出场信号异常关闭。结合实际案例,对现场数据和场联电路设计图进行分析,找出问题的直接原因。通过深入分析电子执行模块的处理逻辑,对比继电电路和电子执行模块在正负电转换过程中无电状态持续时间的差异性,提出相应的解决方案,包括优化电子执行模块处理逻辑、改进场联继电电路。该方案在具体工程项目中得到实际应用,取得较好的实施效果。Liaison signal between yards is used to secure safe and efficient train operation between two yards of a station.When the electronic execution module is adopted to replace the liaison relay circuit between yards,reliable transmission of interlocking information should be ensured,such as conflicting check,signal status of the adjacent yard,and approaching signal between the two yards.During the phased implementation of the liaison signal equipment upgrade project,since the electronic execution module does not well match the not-yet-replaced existing liaison circuit between yards,abnormal stopping of starting signal of the yards may occur due to a short time drop of the check relay during train operations between yards.Based on practical cases,analysis of on-site data and the design drawings of the liaison circuit is made to identify the immediate cause of the fault.Through analyzing the processing logic of the electronic execution module and comparing the the differences in the duration of no electricity state of the relay circuit and the electronic execution module during the process of positive and negative electrical conversion,a solution is proposed,including optimizing the processing logic of the electronic execution module and improving the liaison relay circuit.The solution has been practically applied in specific engineering projects and achieved good implementation results.
