Abstract: Against the backdrop of the special campaign to address wireless communication timeout launched by China State Railway Group Co., Ltd., this paper provides a case study of a typical failure in on-board train control equipment that can repeatedly occur in fixed locations, so as to provide an in-depth analysis of the reasons for triggering the wireless communication timeout of such on-board equipment in the scenario where the CTCS-3 and CTCS-2 Movement Authority (MA) is inconsistent during the RBC handover process of stations with multiple intersecting lines in a hub area. Optimized technical solutions are studied and compared from the professional perspectives of the engineering design of railway signal systems, the organization and dispatching of transportation, the technical conditions of coding sending by the track circuits of train control centers, and the software processing logic of on-board equipment. It is recommended that ATP should not be actively disconnected from the receiving RBC.
Key words: hub, wireless communication timeout, RBC handover, technical scheme
摘要: 结合无线通信超时专项整治工作,通过列控车载设备在固定地点重复发生的典型故障案例,深入分析枢纽地区多线交汇车站RBC移交叠加CTCS-3与CTCS-2行车许可比较不一致场景触发列控车载设备无线通信超时的原因。从信号系统工程设计、运输组织调度、列控中心轨道电路发码的技术条件、车载设备软件处理逻辑等各专业角度,研究并比选优化技术方案,建议ATP不主动与接收RBC拆链。
