摘要
透地通信是一种将分层大地作为传输媒质的通信手段,其利用无线电波技术原理直接穿透大地来实现地面与井下进行信息交流。为了提高复杂环境下的移动通信系统的可靠性、稳定性,基于磁感应技术对无线透地通信进行分析,对无线透地通讯系统的工作原理和依据的理论进行了探讨和分析,并对关键技术进行了研究,对透地通信系统天线的选取方面进行了说明,并分析了透地信道的衰减计算,也对本系统的部分软件进行了介绍。采用磁感应技术无线透地通信系统能够有效地抑制杂波干扰,实现信号的可靠传输,为矿井以及复杂环境下的移动通信的应用和发展提供了必要的理论支撑。
Transmitting communication is a communication means that uses layered earth as a transmission medium.It uses the principle of radio wave technology to directly penetrate the earth to realize information exchange between the ground and the under ground.With the development of through-the-earth communication technology,in order to improve the reliability and stability of mo bile communication systems in complex environments,the wireless terrestrial communication based on magnetic induction technology is analyzed,key technologies is researched,and the selection of antennas for through-the-earth communication systems is described,And the attenuation calculation of the through-ground channel is analyzed,and some software of this system is also introduced.Effec tively suppress clutter interference can be effectively suppressed by using the magnetic induction technology wireless through-theearth communication system,the transmission of signals can be reliable realized,which provides the necessary theoretical support for the application and development of mobile communications in mines and complex environments.
