煤矿斜巷轨道运输图像跟踪系统设计

摘要

针对煤矿斜巷轨道运输运距较长、坡度较大、岔道较多、绞车司机无法实时了解轨道沿线工况而存在较大安全隐患的问题,提出了基于矩阵自动切换的煤矿斜巷轨道运输图像跟踪系统设计方案.该系统通过轴编码器得到矿车在巷道中的位置,当检测到矿车到达某一摄像仪覆盖区域时,采用PLC控制矩阵实现图像自动切换和显示.现场应用结果表明,该系统可靠性高,实用性强.%For problem that track transportation of coal mine inclined drifts has long transport distance,steep slope and many turnoffs,so winch driver cannot know conditions along the track timely,which leads to a big security risk,the paper put forward a design scheme of image tracking system for track transportation of coal mine inclined drifts based on automatic matrix switching.The system obtains tramcar position in the tunnel through shaft encoder,and uses PLC control matrix to achieve automatic image switching and displaying when the tramcar is detected at coverage area of a certain video camera.Field application results show that the system has high reliability and strong practicability.
