针对煤矿井下综采工作面空间狭小、液压支架的传感器数量众多、布线以及维修困难等问题,文中设计一种基于ZigBee与5G无线通信技术的液压支架无线传感器网络系统。首先介绍无线传感器与无线收发器的硬件与软件设计,并研究了ZigBee与5G通信传输数据的方式。然后制作集成液压支架传感器数据的中央控制系统,融合一种适用于液压支架无线传感器网络的分簇式DFD节点故障诊断算法。最后进行测试实验,实验结果表明,文中的无线传感器网络能够将采集的液压支架无线传感器数据传输至无线收发器,通过工作面5G基站传输至井下中央控制系统,再通过支架间电缆传输至支架控制器,满足液压支架对无线传感器网络的高精度、高稳定性和低能耗的要求。该研究可为煤矿井下液压支架电液控制系统无线化奠定基础。
