Design of mine signal transceiver based on WiFi technology

  • In view of defaults of short transmission distance, high power consumption and poor anti-interference ability of existing underground wireless signal transceiver, the paper designed an mine signal transceiver based on WiFi technology by use of ARM9 embedded chip and WinCE operating system. The signal transceiver communicates with shearer monitoring module through Modbus protocol and receives running parameters of shearer through RS485 serial ports. Meanwhile, the signal transceiver connects to underground wireless access point based on TCP/IP protocol in WiFi network, and communicates with sever in monitoring center, so as to realize running state monitoring of the shearer. Application shows that the signal transceiver achieves high real-time transmission performance, low power consumption and strong anti-interference ability.
