基于3PGS和GPS的露天矿出入车辆运输智能管控系统

INTELLIGENT TRANSPORTATION CONTROL SYSTEM FOR VEHICLES ENTERING AND LEAVING OPEN PIT BASED ON 3PGS AND GPS

露天矿区出入卡车运矿过程中的偷矿、乱跑乱拉问题,是一直以来露天矿生产管理面临解决的重要问题。针对出入露天矿区的运矿卡车和社会车辆,通过在采区、采区进出口和卸车区分别安设区内过磅点、通行验证点和卸车过磅点,借助称重传感器技术、RFID识别技术、GPS技术、以太网网络控制技术和系统工程理论与思想,提出防止露天矿运矿过程中偷盗矿石的自动管控策略"三点有序管控法"(3PGS)和防止运矿车辆乱拉乱跑的GPS卡车跟踪策略,并将两种策略相互结合,设计实现了基于3PGS和GPS的露天矿出入车辆运输智能管控系统。该系统在三道庄露天矿的实际应用结果表明:该系统能够有效解决露天矿矿石偷盗、卡车乱拉乱跑及卡车出入管理问题。

Ore stealing and disordered shipping and driving by the trucks when entering and leaving the open pits to transport ores are always an important problem to be solved in the production and management of open pits.In this paper,we propose an automatic control and management strategy “three-point guarding system （3PGS）”to prevent ore stealing in the process of ores transportation in open pits,and the GPS truck tracking strategy to prevent the disordered shipping and driving of the ore-transportation trucks.These strategies are targeted at the ore-transportation trucks and social vehicles entering and leaving the open pits.In 3PGS,three points are arranged,they are the weighing point in mining area,the passing verification point in entrances and exits of mining area,and the weighing point in unloading area.The technologies of weighing sensor,radio frequency identification,GPS,Ethernet network control are employed,the system engineering theory and idea are also used.The two strategies are combined each other in the design and implementation of the 3PGS and GPS-based intelligent transportation control and management system for vehicles in and out the open pits.The result of practical system application in Sandaozhuang open pit shows that the system can be an effective solution to ore stealing,disordered trucks shipping and driving and the management of trucks entering and leaving the open pits.
