摘要
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 problem of communication transmission loss radio communication network in the coal mine recently, the and system establishment in whole underground wireless monitoring position system is designed and constructed taking wireless sensor networks as the hardware platform in this paper. In order to analyze the effect of mine tunnel cross section to the received signal intensity in radio communication, the mirror method is used, Through deducing and simulation, the relation and laws between power loss of high frequency radio signal and distance of transmission in the coal mine are found, then the compensation model for radio loss is built in coat mine.
