Abstract

Abstract: The application of GSM-R network in CTCS-3 train control system has gradually becomes mature. However, the problems of wireless connection timeout have remained a focus in the operation and maintenance work for equipment management bodies. This paper briefly describes the basic principles of CTCS-3 train control system based on GSM-R network and the process of track-train communication, and summarizes and classifies the problems of wireless connection timeout in recent years. It also puts forward the analysis and handling methods for the problems of wireless connection timeout, and lists and studies the typical cases, providing technical support for unifying the handling principles for the problems of wireless connection timeout.

Key words: high-speed railway, GSM-R, CTCS-3, wireless connection timeout

摘要： GSM-R网络在CTCS-3级列控系统中的应用逐渐成熟，然而无线连接超时问题仍是设备管理单位运营维护关注的重点。简述基于GSM-R的CTCS-3级列控系统基本原理以及车地通信流程，对近年来无线连接超时问题归纳分类，提出无线连接超时问题的分析解决方法，并列举典型案例进行研究。为统一无线连接问题的处理原则提供技术支撑。
