无线CBTC信号系统移动授权功能分析

Analysis of the Movement Authority Function for Radio CBTC Signaling System

无线CBTC(基于通信的列车运行控制)信号系统往往采用移动闭塞制式,其列车运行许可主要依靠移动授权功能。为配合信号系统国产化工作,从国际标准中移动授权定义入手,对移动授权分门别类,包括移动授权限制和人工列车授权;详细描述了各类移动授权的原理、办理过程、解锁方法,简要介绍了移动授权的障碍物及回撤现象。结合实际操作场景和故障场景总结了不同类型移动授权之间转换过程,对城市轨道交通无线CBTC信号系统的研究具有借鉴意义。

Radio CBTC signaling system usually adopts moving block, in this condition the tram operation permtssion mainly depends on the movement authority （MA） function. In order to realize the localization of train signaling system, starting from the concept according to international standard, MA is classified including the limit of movement authority and the authorization for manual train, all kinds of MA＇s fundamentals, such as the setting process, releasing method, the obstruction and withdrawal phenomenon of MA are introduced, the transition process between different types of MA and fault scenarios are summarized. This thesis is useful for the future research in the field of urban transit CBTC signaling system.
