中文摘要：

基于ZigBee协议的无线传感器网络具有易部署、可移动、低功耗等优势,如将其部署在井下,结合现有的井下有线传输系统,可提高矿井监测网络的灵活性。为获得2.4 GHz无线传感器节点在井下的传输特性,在井下工作面完成了实地试验,并对试验结果进行分析。结果表明,2.4GHz的无线传感器节点在井下工作面的有效传输距离可满足ZigBee协议的要求。

英文摘要：

The wireless sensor network based on ZigBee agreement had advantages of easy layout,mobile,low power consumption and others.If the wireless sensor network could be applied to the underground mine,in combined with the existing the line transmission system,the flexibility of the mine monitoring and measurement network could be improved.In order to have the underground mine transmission features of the node for the 2.4 GHz wireless sensor,the experiment was completed in the underground mine gateway of the coal...
