摘　　要：轨道电路是利用钢轨作为导体,用以检查列车占用状态并向车载设备发送相关机车信号的地面轨旁设备。当衰耗过大使得一段轨道电路无法正常工作时,则需要用两段或两段以上轨道电路来完成,而衰耗过大通常是因为轨道电路长度过长或线路环境等原因引起的。客运专线区间闭塞分区的长度一般情况下均大于一段ZPW-2000A轨道电路的长度,因此,在设计阶段需要对其进行轨道电路分割,以保证其功能的正常完成。然而由设计者人工进行轨道电路的分割不仅效率低下且准确性难以保证。因此,借助计算机辅助软件替代人工完成轨道电路分割设计工作是非常必要的。文章提出了一套完善的轨道电路自动分割算法,以该算法为核心,开发出了辅助软件,并应用于工程实践。Track circuit is a ground trackside equipment using the rail as conductor to check the status of the train occupancy and sending the related the locomotive signal to the mobile unit. If the loss is too large which makes one section of track circuit cannot work normally,two or more sections of track circuits are required to finish the work,which is caused by many reasons,such as excessive long track circuit or circuit environment,etc. The length of high speed railway block section is usually much longer than that of ZPW- 2000 A track circuit. So,the track circuit should be cut into two or more sections in the design stage to ensure the function can be executed normally. But if the designers do the cut work manually,not only the efficiency will be low,but also the accuracy cannot be guaranteed. It＇s very necessary to finish the track circuit cut work by computer assistant software which can substitute the manual method. This paper presents a thorough automatic cut algorithm for track circuit cut,by which assistant software has been developed,and been applied in some actual railway projects.
