针对当前无线传感器网络在煤矿安全监测过程中存在可靠性不强的问题,设计了一套基于JN5139的无线煤矿安全监测系统。系统采用英国Jennic公司的无线收发与微控制器一体的JN5139模块及相应ZigBee软件开发包设计无线传感器网络终端设备节点和协调器节点的软硬件,采用ZigBee协议与Uucode编解码技术相结合提高数据传输的可靠性,将矿工携带的无线通讯模块地址与矿工身份信息(身高、体重、血型)绑定,使瓦斯浓度检测结果唯一对应某一特定矿工所处位置,提高瓦斯浓度分析的科学性和救援效率。实验结果表明,该检测系统运行稳定可靠,具有一定的推广价值。
Aiming at the current wireless sensor network in coal mine safety monitoring process is not reliable, a set of wireless coal mine safety monitoring system based on JN5139 is designed. The system uses the JN5139 module and corresponding ZigBee software development kit which integrates wireless transceiver and microcontroller in the UK Jennic Company to design the hardware and software of the node device and coordinator node of the wireless sensor network terminal device. The combination of ZigBee protocol and Uucode codec technology improves data transmission The reliability of the miners to carry the wireless communication module address and miners identity information (height, weight, blood type) binding, the gas concentration test results corresponding to a specific miners where the location to improve the gas concentration analysis of the scientific and rescue effectiveness. The experimental results show that the detection system is stable and reliable, and has certain promotion value.
