Abstract

Abstract: Targeting at the operational requirements of complex signaling systems in different European countries, this paper analyzes the requirements for train control over dwelling and coupling operations of the ETCS-2 train control system based on the Radio Block Center (RBC). Based on the route status obtained from the interlocking, it proposes a scheme for providing train dwelling protection and ensuring coupling operation safety from the perspective of RBC. Four protection solutions are proposed, i.e. sending unconditional emergency stop message after route release, shortening current Movement Authority (MA) to train front end, issuing new MA of OS mode profile, and maintaining current MA while adding MA supervision. Moreover, feasibility issues of these four solutions are discussed from two aspects, i.e. safety and availability. Finally, maintaining current MA while adding MA supervision is selected as the application scheme for actual projects. Thus, system safety is improved without any impacts on system availability.

Key words: coupling operation, train protection, RBC, movement authority, ETCS

摘要： 针对欧洲各国不同信号系统复杂制式的运营需求，分析ETCS-2级列控系统基于无线闭塞中心（Radio Block Center，RBC）控制列车停站以及重联作业需求，根据从联锁获取的进路状态，从RBC角度提出列车停站防护并保障重联作业安全的方案，在进路解锁后给列车发无条件紧急停车、撤销移动授权至车头、补发引导模式曲线授权、保持既有授权并增加授权监督防护4种防护方案，并同时从安全性和可用性两方面论述所提方案的可行性问题。最终选择保持既有授权并增加授权监督防护作为实际工程应用方案，不影响系统可用性的前提下提升系统安全性。
