摘要

摘要: 为提高磁感应透地通信系统的传输性能，扩大磁感应透地通信系统的传输距离，研究了多输入单输出（MISO）磁感应透地通信系统：建立了MISO模型，并根据基尔霍夫定律建立KCL方程，获得了MISO模型的收发功率，分析了MISO磁感应透地通信系统的路径损耗；研究了MISO模型磁感应强度分布特性，得出了MISO磁感应透地通信系统的信号传输特点。研究结果表明：当发射线圈具有相同电流时，MISO模型较单输入单输出（SISO）模型的路径损耗明显降低，发射线圈越多，则路径损耗越小；当发射功率相同时，接收功率近似与发射线圈个数呈正比，接收端磁感应强度随发射线圈个数的增加而增大；MISO模型能够有效提高磁感应透地通信系统的传输距离，当各发射线圈通有相同电流时，MISO(1,2)模型的传输距离约为SISO模型的1.11倍，MISO(2,2)模型的传输距离约为SISO模型的1.26倍。

Abstract: In order to improve transmission performance and increase transmission distance of magnetic induction through-the-earth communication system, multiple input single output (MISO) magnetic induction through-the-earth communication system was studied. A MISO model was established and KCL equations were built according to Kirchhoff law, so as to get transmitting and receiving power. Path loss of MISO magnetic induction through-the-earth communication system was analyzed. Magnetic induction density of MISO model was researched and signal transmission characteristics of MISO magnetic induction through-the-earth communication system were obtained. The results show that: When transmitting coils have the same current, path loss of MISO model is significantly lower than that of single input single output (SISO) model.The more transmitting coils there are, the smaller the path loss will be. When transmitting power is the same, receiving power is proportional to the number of transmitting coils, and magnetic induction density at receiving end increases with the number of transmitting coils increases. The MISO model can effectively increase transmission distance of magnetic induction through-the-earth communication system. When all transmitting coils have the same current, transmission distance of MISO(1,2) model is about 1.11 times than that of the SISO model, and the transmission distance of MISO(2,2) model is about 1.26 times than that of the SISO model.
