摘要
保护区段(Overlap)设置是ATP系统对列车超速冒进防护的关键技术,通常,保护区段设置在行车许可终点(EOA)之后,由联锁子系统建立。保护区段与众多因素相关,其计算模型也是各有侧重,文章根据实际折返站具体的参数,计算保护区段对基于通信的列车控制(CBTC)模式下行车的影响,并分析保护区段与折返效率的关系。仿真计算结果显示:保护区段设置过小,会导致列车进站行车缓慢欠停,同时会导致折返追踪间隔过长,降低折返效率,因此,需综合考虑、合理设置保护区段。
The setting of overlap is the key technology of train over speed protection for automatic train protection system. The overlap is conventionally set up controlled by the interlock subsystem after the end of movement authority （EOA）, related to a number of factors, and its calculation model is diferent. According to the specifc parameters of the actual turnback station, the article calculated the driving infuence of overlap under the mode of communication based train control （CBTC）, analyzed the relationship between the overlap and turnback efciency. The results of simulation and calculation showed that if the overlap was too small, it would lead to slow driving and less stopping, also lead to the turnback tracking interval too long, and reduce the efciency of turnback. Therefore, it was needed to consider the reasonable overlap.
