摘　　要：针对动车段(所)分割信号机处,列车运行监控装置(LKJ)控制列车行车许可终点易与实际排列进路不一致等问题,深入研究LKJ行车作业方法,以进一步提高作业效率。结合LKJ工作原理、控车策略,在不同行车许可终点情形下,分析将列车接入G2停车位5种行车作业方式的优缺点。提出2种优化方案:增加LKJ股道号,即针对不同行车许可终点,预置2组股道数据,LKJ根据实际排列进路调用相应线路数据,形成控车曲线;增设应答器组,用于提供线路基础信息、临时限速、侧线进路等数据,以区分长/短进路。经过方案比选,推荐采用增加LKJ股道号的方案,确保行车许可与实际排列进路一致,保障行车安全。The end of train movement authority based on the LKJ tends to be inconsistent with the actual route arrangement at the division signal of the EMU depot.To solve the problem,the LKJ operation method is studied in depth to improve the operation efficiency.According to the working principle of the LKJ and the train control strategy,the advantages and disadvantages of the five operation modes of connecting the train to G2 parking space are analyzed under the conditions of different ends of authority.Two optimization schemes are proposed:one is to increase the LKJ track numbers,that is,two sets of track data are preset for different ends of authority and the LKJ calls the corresponding line data according to the actual arrangement of routes to form a train control curve;the other is to add a balise group to provide basic line information,temporary speed limit,side route and other data to distinguish long/short routes.Through comparison and selection,it is recommended to increase the LKJ track numbers to ensure the consistency between the train movement authority and actual route arrangement and the operation safety.
