摘　　要：针对目前井下信号收发器存在信号传输距离短、传输速率低、抗干扰能力差、功耗大等问题,设计了一种基于RS485串口通信技术和无线WiFi技术的矿井信号收发器通信模块。该模块采用WinCE嵌入式系统,与井下监控终端通过RS485接口进行基于Modbus协议的数据通信,将监控终端采集到的数据通过WiFi网络以TCP/IP协议发送至无线接入点,并与井上监控中心服务器进行数据双向通信。测试结果表明,该信号收发器通信模块具有较高的数据传输实时性和可靠性。In view of problems of short transmission distance,low transmission rate,poor antiinterference 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 realtime and reliable data transmission performance.
