基于列车碰撞预警系统（TCEWS）的探索和发展，我国高速列车运行安全保障覆盖铁路信号系统已成为现实。随着北斗卫星导航系统（BDS）的快速发展，精确、高效的卫星导航的出现引发了铁路运输系统的一场革命。全球导航卫星系统（GNSS）被推荐为基于位置的铁路应用中最自主、最灵活和最具成本效益的选择，这已成为一种普遍的信念。然而，列车碰撞预警系统测试中基于BDS的定位的现场经验表明，应用方面应考虑几个问题。根据性能要求，分析了基于BDS的列车碰撞预警系统方案的要点。通过与BDS和GPS启用的列车碰撞预警实施的现场测试结果的比较和讨论，证明了BDS在这种新的安全相关服务中的巨大潜力。
Based on the exploration and development of Train Collision Early Warning System (TCEWS), the safety assurance overlay for high-speed train operation over the railway signaling system is becoming a reality in China. As the rapid development of BeiDou Navigation Satellite System (BDS), availability of precise and effective satellite navigation encourages a revolution in railway transportation system. It is becoming a general belief that Global Navigation Satellite System (GNSS) is recommended as the most autonomous, flexible and cost-efficient choice for location-based railway application. However, field experience of BDS-based positioning in train collision warning system tests suggests that several issues should be considered for application aspects. According to the performance requirements, this paper analyzes some significant points of the BDS-based train collision early warning system scheme. It is complemented by comparison and discussion with field test results of BDS and GPS enabled train collision warning implementations, which demonstrate the great potentials of BDS in this novel safety-related service.
