摘要

摘要: 综合分析了现有无线透地通信研究现状，比较了地电极、弹性波及磁感应透地通信的性能，得出磁感应透地通信性能优于其他2种透地通信方式；重点阐述了磁感应透地通信信道模型，提出了磁感应透地通信亟待解决的关键技术问题和可行的解决方法；同时，综述了现有的磁感应透地通信发射机与接收机设计方案。结合当前研究和应用热点，提出了透地通信今后的重点研究方向：磁信号本身衰落较大是制约磁感应透地通信进一步发展的关键因素；磁感应透地通信的发射机、接收机及传输机制都需要完善；应用在矿井下的透地通信系统不仅要将发射功率控制在安全范围内，考虑通信距离与发射功率的折中关系，还要考虑如何抑制复杂的井下电磁干扰。

Abstract: Research status of existing wireless through-the-earth communication was comprehensively analyzed, performances of ground electrode, elastic wave and magnetic induction communication were compared, and result was got that performance of the magnetic induction communication is better than the other two kinds of communication methods. The magnetic induction communication model was emphasized, and on this basis, key technical problems and feasible solutions of the magnetic communication were put forward. Besides, design schemes of existing magnetic communication transmitter and receiver were elaborated. The future research directions of through-the-earth communication was put forward considering current studies and popular applications: large magnetic signal fading is a key factor which restricts further development of the magnetic induction communication; transmitter, receiver and transmission mechanisms of the magnetic induction communication need to be improved; through-the-earth communication system used in underground mine not only needs to control transmission power in safety range, consider compromise relationship between communication distance and transmission power, but also needs to consider how to suppress complex underground electromagnetic interference.
