摘　　要：现有轨道运输监测大多采用轨道电路和压力传感器,存在机械磨损和产生电火花的可能性,影响安全生产;加上传感器设置在轨道下面,井下巷道积水、环境恶劣,影响传感器性能,系统维护困难、可靠性差。本文提出采用视频图象处理方法,利用模式识别、最优阈值和几何相似理论,实现非接触式的监控与测量。研究结果表明:系统可对列车运动速度、运动方向、列车异常情况、列车有效载荷等数据进行有效监测。系统运行安全、稳定。Existing surveillance and measure of railway transportation under mine mostly uses railway circuit and pressure sensor. But it can produce the possibility of electrical spark, which affects safety in production. In addition, sensor installation under railway, much water under mine, and bad environment will affect performance of sensor. At the same time, system maintenance will become very difficult, and the system’s reliability will become lower. This paper puts forward non- contact surveillance and measure...
