摘　　要：为应对一线二列位动车段(所)的特殊运营场景及运输需求,从联锁图表编制、分割信号机的联锁关系以及进路解锁3个方面,分析计算机联锁系统的特殊设计。通过对比各类应用方案及适用场景,给出建议方案;提出需结合站场布局及设备间接口内容,确定是否采用小进路方案编制联锁图表;在建立长接车进路时,应检查分割信号机的开放状态,建议按列车信号机标准,为分割信号机设置主副灯丝转换,并将主灯丝断丝纳入灯丝报警,同时为分割信号机增设引导功能;长进路正常解锁时应增加停稳逻辑判断并延时解锁,增加人工解锁分割信号机防护进路的功能,合理设置延时解锁时间。可为后续动车段(所)相关工程设计及产品制造提供思路及借鉴。In response to the special operational scenarios and transportation requirements of EMU depot with two trains stopping on one track,the special design of the computer based interlocking system is analyzed from three aspects including the compilation of interlocking table,interlocking relationship of segmentation signal,and route release.It is proposed that the station layout and equipment interface contents shall be combined to determine whether compile interlocking charts by the plan of auxiliary route.The status of the segmentation signals shall be checked in establishing a long receiving route,and the suggestions are put forward including of setting main-auxiliary filament conversion for segmentation signal based on the train signal,alarming the main filament broken wire failure,and adding calling-on function to the segmentation signals.The stopping logic judgement and delayed unlocking shall be added when the long route is unlocked,the function of manually unlocking the protective route of the segmented signal shall be added,and the delayed unlocking time should be set reasonably.These suggestions can provide ideas and references for the subsequent engineering design and product manufacturing of EMU depots.
