摘　　要：针对高速列车运行中,列车本身无有效的安全监控装置,为填补高速列车车载线路安全监控的空白,根据高速列车运行环境、制动距离及安全监控需求,对可能的探测技术进行性能比选,分析表明以制冷型中波红外探测技术为核心的监控系统能够实现远距离的实时高分辨探测。在此基础上完成系统总体参数设计,并完成一套长焦距、小尺寸、100%冷阑匹配的光学子系统设计。最后搭建整机系统,并进行铁路现场实验测试。研究结果表明:该系统能够在雾霾等不良气象条件下昼夜对列车前方4 km外的铁轨以及障碍物等目标进行实时可靠探测,能为高速列车运行提供一种新型主动安全监控技术。The high-speed trains are currently not equipped with effective onboard safety monitoring device when operating.In order to fill the gaps in onboard safety monitoring of high-speed train line,this paper compared the performance of several detection technologies based on the operation condition,the braking distance,and the security monitoring requirement of high-speed train operation.The analysis results show that the monitoring system based on cooled mid-wave infrared detection technology can achieve real-time high-resolution remote detection.On this basis,the overall parameter design of this system was completed,and a set of optical sub-system long focal length,small size,and 100%cold shield efficiency were designed.Finally,the whole system was set up and tested in railway field.The experiment results show that the system can reliably detect the railway and obstacles 4 km ahead of the train day and night under adverse weather conditions such as fog and haze,which provides a new active security monitoring technology for high-speed train operation.
