摘要:
目前的城市轨道交通信号系统广泛采用基于计轴的次级列车定位子系统。在实际的运营应用中，计轴系统一旦发生故障，在有些情况下将对正常运营产生较大的影响。同时，计轴系统维护工作量大，易受电磁环境干扰，更换工艺繁琐。尤其是随着系统投用时间的增加，计轴故障的问题越发凸显，在既有线路的信号改造项目中亟待解决。为解决计轴系统带来的问题，提出了新的列车主动定位技术。该技术基于地面应答器，采用车地系统结合的办法，为无计轴CBTC(基于通信的列车控制)系统提供了与计轴系统相同安全等级的列车次级定位通用检测方案。将该新技术与计轴系统进行了性能比较，认为该技术在新线线路建设和既有线路改造项目中具有良好的应用前景。
Abstracts:
Current rail transit signaling system widely adopts secondary train positioning subsystem based on axle counting. In practical operation application, once taxle counter system faults occur, major impacts might be caused to normal operation under certain circumstances. Meanwhile, axle counter system maintenance demands large workload, being easily interfered by electromagnetic environment, and has complicated replacement process. Especially with the increasing service time after system launch, axle counter system faults grow more evident, seeking for urgent treatment in existing line signaling reconstruction projects. In order to solve this problem, a new train active positioning technology is proposed. The technology is based on the ground balise, together with onboard and wayside systems, a train secondary positioning general detection scheme which is at the same safety level as the axle counter system is provided for no-axle-counter CBTC system. By comparing performance of new technology and that of axle counter system, it is believed that the technology has promising future in application in new line construction and existing line reformation.
