大湾区城际铁路CTCS2+ATO车次号自动更新方法研究
Research on Automatic Update Method for Train Running Number of CTCS2+ATO System for Intercity Railways in Greater Bay Area
摘要
Abstract
With the widespread adoption of CTCS2+ATO train control systems in intercity rail transport within the Guangdong-Hong Kong-Macao Greater Bay Area,for lack of the train operation monitoring device,existing EMUs equipped with the CTCS2+ATO onboard train control equipment are incapable of automatic update of train running number,which affects the efficiency of train operations and hinders the development of intercity rail transport systems towards bus-like operations.This research analyzes the reasons of the absence of automatic update of train running number in the current signaling system,and proposes the solution of modifying the interface protocol and optimizing the transfer logic of train running number without changing the hardware interface between existing devices to enable the automatic update of train running number.It also tests the update situation of train running number in different scenarios by establishing a laboratory simulation test platform.The test results show that the onboard signaling equipment is capable of automatic update of train running number,which provides reference for improving the functionality of the CTCS2+ATO system for intercity railways.关键词
