一种基于三轴正交接收线圈的磁感应透地通信方案OA北大核心CSTPCD
A magnetic induction through-the-earth communication scheme based on three-axis orthogonal receiving coil
为提高磁感应透地通信系统的灵活性和覆盖范围,提出了一种新型透地通信方案,该方案采用单轴空气线圈作为地面发射机天线,用3个相同参数的空气线圈作为接收机天线.首先,对通信信号进行空间分集接收,使通信系统的井下接收机能够以任意姿态地摆放于巷道之中,并能实现更广范围的信号覆盖;其次,为消除因接收线圈间近场耦合作用而产生的信号干扰,将接收机3个天线设置成共用1个圆心且两两相互正交的空间结构;最后,以远距离通信场景下收发线圈间的弱耦合情况为依据,建立一套与接…查看全部>>
In order to improve the flexibility and coverage of the magnetic induction through-the-earth(TTE)communication system,a new TTE communication scheme was proposed.The scheme uses a single axis air coil as the ground transmitter antenna and three air coils with the same parameters as the receiving antenna.Firstly,the communication signal was received by space diversity,so that the underground receiver of the system can be placed in the tunnel in any posture an…查看全部>>
