针对煤矿井下胶带跑偏、急停开关故障发生时需要一一排查寻找故障点而耽误检修时间的问题,设计了基于CAN总线通信的胶带开关定位系统。该系统采用主-从控制模式,主从分站均以AVR单片机为微处理器,分站实时采集各个开关的开闭状态,并将采集到的状态信息通过CAN总线实时传送到主站,主站控制继电器状态实现胶带急停并通过串口与上位机进行通信,上位机实时显示各个开关状态,进而指导故障排查。系统在现场应用实现了定位、控制和显示的设计目标,具有重要的实际应用意义。
For coal mine belt deviation, emergency stop switch failure occurred one by one to find the fault point to check and delay the maintenance time, the design of the CAN bus communication tape switch positioning system. The system uses the master-slave control mode, the master and slave substations AVR microcontrollers are microprocessors, sub-station real-time acquisition of the various switches on and off state, and the acquisition of the state information transmitted through the CAN bus in real time to the main station, the main Station control relay status tape emergency stop and communicate with the host computer through the serial port, the host computer real-time display of each switch status, and then guide troubleshooting. The system has realized the design target of locating, controlling and displaying in the scene of application, have important practical application meaning.
