矿井机车防撞预警系统设计

Design of anti-collision warning system for mine locomotive

针对现有井下机车防撞系统对于弯道、坡道、道岔等复杂地形没有相应的处理措施、易引起误报的问题,设计了一种矿井机车防撞预警系统。该系统利用二维扫描激光雷达实现了障碍物检测,雷达扫描角度为270°,识别距离大于60m;通过RFID技术实现了弯道等特殊地形的检测及机车实时定位,并可获取机车速度、方向、所在轨道等运行状态;通过Lora无线数据透传技术实现了与相邻机车间的信息交互。现场工业性试验结果表明,该系统能够实现机车准确定位,特殊巷道地形识别、障碍物/地形识别实时性好,可满足井下应用需求。

In view of problem that existing underground locomotive anti-collision system had no corresponding treatment measures for complex terrain such as corners,ramps and ballasts,and it was easy to cause false alarms,an anti-collision warning system for mine locomotive was designed.The system uses two-dimensional scanning laser radar to realize obstacle detection,radar scanning angle is 270°and recognition distance is more than 60 m.Special terrain detection such as corners and real-time positioning of the locomotive are realized by RFID technology,and operating status of the locomotive speed,direction,and track can be obtained.Information interaction with adjacent locomotive is realized by Lora wireless data transparent transmission technology.The on-site industrial test results show that the system can accurately locate the locomotive,and the special roadway terrain identification and obstacle/terrain recognition have good real-time performance,which can meet the needs of underground applications.
