Design of communication module of mine signal transceiver

In view of problems of short transmission distance, low transmission rate, poor anti-interference ability and high power consumption of existing underground signal transceiver, the paper designed a communication module of mine signal transceiver based on RS485 serial communication and wireless WiFi technology by use of WinCE embedded system. The module communicates with monitoring terminal through RS485 interface based on Modbus protocol. Meanwhile, the module sends the data collected by monitoring terminal to wireless access point based on TCP/IP protocol in WiFi network, and communicates with server in monitoring center. The test results show that the module achieves high real-time and reliable data transmission performance.
