- 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.
