基于射频识别(RFID)技术和可编程逻辑控制器设计了矿井内单车道固定会车点车辆运行控制信号系统。采用射频识别(Radio Frequency Identification,RFID)技术,通过设置在巷道内的射频读卡器完成对车载电子标签的监测,获得车辆定位信息及优先级。采用控制器局域网(Controller Area Net,CAN)总线技术实现现场射频读卡器与控制设备之间的通信。采用工业以太网技术实现管理层、控制层设备之间的通信,实时、准确地将信号灯显示信息及读卡器获得的车辆信息传送到PLC(Programmable Logic Controller,可编程序控制器)及控制接口计算机上。利用PLC技术实现了对信号灯的自动控制和人工控制。采用编程软件STEP 7通过梯形图语言编写控制程序。在组态王软件中仿真证明系统能够安全高效地实现矿井内单车道车辆运行控制。
Based on radio frequency identification (RFID) technology and programmable logic controller, a single-lane fixed-point vehicle operation control signal system in a mine is designed. Radio frequency identification (Radio Frequency Identification, RFID) technology is used to monitor the on-board electronic tags through the RF card reader installed in the roadway to obtain the vehicle positioning information and priority. The controller area network (Controller Area Net, CAN) bus technology is used to realize the communication between the on-site RF card reader and the control device. The industrial Ethernet technology is used to realize the communication between the management layer and the control layer devices and transmit the signal display information and the vehicle information obtained by the card reader to the PLC (Programmable Logic Controller) and the control interface in real time and accurately. On the computer The use of PLC technology to achieve the automatic control of signals and manual control. Using programming software STEP 7 to write control programs in ladder language. The simulation in KingView software proves that the system can safely and efficiently control the running of single lane vehicle in mine.
