An Integrated Communication System Based on Personnel Orientation in Mine;
一种基于人员定位的矿井综合通信系统
With the problems of incomplete communication function and complicated techniques and realization in mine,an wire- less communication system based on personnel orientation is developed.
近年来,煤矿高瓦斯矿井的数量在不断增加,矿难频频发生;为了有效进行矿工管理,保证抢险救灾、安全救护的高效运作,很有必要在矿井下建立人员定位系统;针对目前矿井井下通信系统功能不完善,技术与实现复杂的现状,设计了一种基于井下人员定位的无线通信监控系统;阐述了基于单片射频收发芯片nRF9E5的无线传输系统的结构功能及工作原理,提出了系统的硬件设计、软件流程以及可靠的通信协议;实践表明,该系统控制简单,使用方便,工作稳定性很高,能够在井下可靠地实现点对多点的无线通信。
There are many kinds of jamming in the mine environment,and in particular,the electromagnetic jamming exercises a great influence on the personnel orientation system.
矿井中存在的电磁干扰严重影响了井下人员定位系统的无线传输,针对此问题,提出了利用nRF905芯片及多频道跳频技术来提高井下人员定位系统的抗干扰能力,并对该定位系统的结构功能、工作原理、硬件设计及软件流程做了说明和介绍。
