| 摘 要： | 针对现有煤矿语音通信系统常采用有线方式而导致发生事故时无法保证通信可靠性的问题,提出一种基于ZigBee技术的无线语音通信系统设计方案,重点介绍了该系统无线语音通信节点的软、硬件设计方案。在实验室环境下测试了不同距离下语音通信节点的收包率与信号强度,结果表明,当节点距离通信距离>60m时,丢包率逐渐变大,且信号强度随节点距离的增大而减小,由此确定基站间距为60m,基站覆盖半径为60m。

| Abstract: | For problem that existing voice communication systems usually use wired communication mode,which cannot guarantee reliability of communication when an accident happens,a kind of wireless voice communication system based on ZigBee technology was proposed.The hardware and software design schemes of wireless voice communication node were described in detail.Reception rate and RSSI were tested under laboratory environment when terminal nodes were in different distances.The test result showed when communication distance between nodes is more than 60 m,packet loss rate is increasing,while RSSI decreases with increasing of distance between nodes.Thus distance between base stations is decided as 60 m,and coverage radius of the base station is as 60 m. |
