摘　　要：截至2021年年底,我国城市轨道交通运营里程已接近9000 km,其中包括直流牵引地铁项目、交流牵引地铁/市域项目、城市有轨电车项目、磁悬浮项目、跨座式单轨项目等。适应多种运营环境是信号控制系统及其子系统需要面对的关键问题。如何在复杂运营环境下保持系统安全性以及可用性变得尤为重要。区段占用检测设备的环境适应性、安全性、可用性会直接影响信号系统乃至城市轨道交通项目的安全运营。文章针对现有城市轨道交通中不同原理以及架构的占用检测设备进行对比、分析,探究一种适应性强、安全可靠的占用检测手段。By the end of 2021,the operating mileage of urban rail transit in China has reached about 9000 km,including DC traction metro projects,AC traction metro/municipal projects,urban tram projects,maglev projects,straddle monorail projects,etc.Adapting to a variety of operating environments is a key issue for signal control systems and their subsystems.How to maintain system safety and availability in a complex operating environment becomes particularly important.The environmental adaptability,safety and availability of section occupancy detection equipment will affect the safe operation of signal system and even urban rail transit projects directly.This paper compares and analyzes the occupancy detection equipment with different principles and architectures in the existing urban rail transit,and explores an adaptive,safe,and reliable occupancy detection method.
