基于天线分集技术的WSN在矿井监控系统中的研究与应用

内容简介：针对煤矿井下特殊的地理环境，分析了井下易产生多径衰落的原因，对煤矿井下无线传输特性进行了研究，在此基础上设计了一款多天线无线传感器节点，在无线传感器网络中引入天线分集技术来降低射频信号的噪声。试验结果表明，与传统的单天线技术相比，天线分集技术的引入提高了信道容量，在一定程度上改善了信号接收强度，保证了信号的传输质量。

Abstract：In this paper, analysis was made on the cause of multi-path fading in coal mines according to their special geographical environment, and study was carried out on the characteristics of wireless transmission in coal mines. On this basis, a multi-antenna wireless sensor network was designed and the antenna diversity technology was applied in this network to reduce the noise of radio-frequency signal. The test results showed that the application of the antenna diversity technology improved the channel capacity as compared with the traditional single antenna technology, increased the signal receiving intensity to some extent, and ensured the quality of signal transmission.
