针对目前煤矿井下无线通信网络存在的通信传输损耗及系统构建方面的问题,以无线传感器网络为硬件平台,设计构建井下无线检测定位系统,并运用镜像法分析巷道截面模型对无线电通信接收信号强度的影响,通过研究推导并结合仿真,找到煤矿井下高频无线电信号功率损耗与传播距离的关系和规律,从而建立了井下巷道无线损耗的补偿模型。
Aiming at the problems of communication transmission loss and system construction in coal mine underground wireless communication network at present, the wireless sensor network is used as hardware platform to design and construct underground wireless detection positioning system, and the mirror image method is used to analyze the influence of roadway cross-section model on the received signal strength of radio communication Influence, and through the study deduced and combined with simulation to find the relationship and law between power loss and propagation distance of high-frequency radio signal in coal mine, so as to establish the compensation model of wireless loss in underground mine roadway.
