摘要
天线磁感应透地通信技术是一种应急通信技术。它利用甚低频或低频电磁波穿透岩层,实现透地话音及数据通信,可为采矿业、运输业、公共安全等部门提供应急通信保障。随着通信技术和计算机技术的迅速发展,天线磁感应电磁波透地通信系统由单向通信变为了现在的双向通信。当前,设备的尺寸进一步减小,使得天线磁感应电磁波透地通信技术得到了更加广泛的应用。简要说明三种主要透地通信技术,探讨天线磁感应透地通信技术的机理、特点及其应用情况.。
As a sort of emergency communication technology, antenna magnetic induction through-the-Earth communication technology utilize very low frequency(VLF) band and low frequency(LF) band electromagnetic wave to strike the rock, realize through-the-Earth voice and data communication. It provides emergency communications support for the mining, transportation, and public safety sectors. With the rapid development of communication technology and computer technology, Antenna magnetic induction through-the-earth communication system has changed from one-way communication to two-way communication. The size of the equipment is further reduced, which makes antenna magnetic induction through-the-Earth communication technology more widely used. There gives brief illuminate about three sort primary through-the-Earth emergency communication technology. The mechanism, characteristic and application instance of antenna magnetic induction Through-the-earth Emergency communication technology are discussed.
