基于多种传感技术融合的高铁周界入侵监测报警技术及应用

High Speed Railway Perimeter Intrusion Monitoring and Alarm Technology Based on Fusion of Multiple Sensing Technologies and Its Application

铁路运输的行车安全是重中之重。人员违规上道、非法破坏或穿越铁路栅栏等人为因素,落石塌方、泥石流等客观自然因素,随时对列车行车安全构成重大威胁,高铁周界入侵报警监测技术对保证高铁安全运营具有重要作用。结合现阶段高铁周界入侵监测系统应用的具体情况及不足,针对不同场景的关键需求设计不同的监测方案,包括振动光纤+视频融合、毫米波雷达+双光谱融合、激光雷达+视频融合等3种技术方案,并将3种方案在银兰高铁中兰段宝台山隧道口(K357+147)进行现场部署及实测,测试结果表明应用效果良好。

Train operation safety is a top priority for railway transportation.Human factors such as on-track operation violating the rules,illegal damage or crossing of railway fences as well as natural factors such as rockfall,landslide and debris flow pose major threats to train operation safety at any time.High speed railway perimeter intrusion alarm and monitoring technology plays an important role in ensuring the safe operation of high speed railway.In view of the current conditions and inadequacies in application of high speed railway perimeter intrusion monitoring system,to address key requirements of various scenarios,this paper introduces three different monitoring schemes,respectively for vibration optical fiber+video fusion,millimeter-wave radar+dual-spectrum fusion,and lidar+video fusion.All the three schemes were applied at the port(K357+147)of Baotaishan Tunnel on Zhongwei-Lanzhou Section of Yinchuan-Lanzhou HSR.The test results show that the application effect is good.
