【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]:In this paper, the current research situation of wireless penetrating earth communication is comprehensively analyzed, and the performances of ground electrode, elastic and magnetic permeable earth communication are compared, and the results show that the performance of magnetic permeable earth communication is better than that of other two kinds of earth penetrating communication modes. In this paper, the channel model of magnetically permeable earth communication is expounded, and the key technical problems and feasible solutions to be solved urgently are put forward. At the same time, the design schemes of the transmitter and receiver for magnetic induction permeable earth communication are summarized. Combined with the current research and application hot spots, this paper puts forward the key research direction of penetrating earth communication in the future: the large fading of magnetic signal itself is the key factor restricting the further development of magnetic inductive penetrating earth communication, the transmitter of magnetic inductive earth penetrating communication, The receiver and transmission mechanism need to be improved, and the transmission power should not only be controlled in the safe range, but also the compromise between the communication distance and the transmission power should be considered. Also consider how to suppress the complex underground electromagnetic interference.
