摘要
针对露天矿山采用公路开拓方式存在的大型运输卡车体量巨大、司机视角差、易发生危险事故的问题,设计了基于飞行时差技术的露天矿山卡车防撞预警系统。该系统采用具有测距功能的WSN模块,通过无线测距方法和三角定位法确定大型车辆、辅助车辆和人员的位置,并进行方位显示和报警提示。测试结果表明,该系统测距距离不低于200m,误差不大于4m,能够满足防撞预警系统的要求,同时降低了系统成本和功耗。
In view of problems of large volume of transport truck,poor viewing angle of driver and easily leading to dangerous accident,the paper designed collision warning system of truck for open pit mine based on TOF technology.The system uses WSN modules with ranging capabilities,and determines locations of large vehicles,support vehicles and personnel through wireless ranging method and triangulation location method,and realizes orientation display and alarm.The test results show that ranging distance of the system is no less than 200 m,the error is no greater than 4 m,which can meet requirements of collision warning systems,meanwhile reduces system cost and power consumption.
