摘　　要：多维无线电力传输是胃肠道胶囊机器人发展的关键。为了解决新型胶囊机器人功能不断增加,而传统三维接收线圈占用内部空间过大的问题,本文提出了一种三维组合式发射线圈,能够通过调制通过各维线圈的电流来产生动态的三维磁场。本文首先介绍了无线供能系统的工作原理,然后对发射系统产生的空间磁场进行了有限元分析。最后利用搭建的实验平台进行实验,验证了仿真结果的准确性并确定了接收线圈感应最大接受电压的姿态。试验结果表明,当发射系统在中心点处产生相等的三维磁场分量时,负载接收能量超过630 mW。此外,发射系统附近边缘区域的位置稳定性超过80%,确保胶囊机器人能够平稳的运行。Multi-dimensional wireless power transmission is the key to the development of gastrointestinal capsule robots.To solve the problem that the functions of new capsule robots are increasing,and the traditional three-dimensional receiving coils take up too much internal space,this article proposes a three-dimensional combined transmitting coil that is able to generate a dynamic three-dimensional magnetic field by modulating the currents passing through each dimensional coil.Firstly,the working principle of the wireless energy supply system is introduced.Then,a finite element analysis of the spatial magnetic field generated by the transmitting system is implemented.Finally,experiments are conducted by using the constructed platform to evaluate the accuracy of the simulation results and determine the attitude of the receiving coil to sense the maximum receiving voltage.The experimental results show that the load-received energy exceeds 630 mW when the transmitter system generates equal three-dimensional magnetic field components at the center point.In addition,the positional stability of the edge region near the transmitter system exceeds 80%,which ensures that the capsule robot can operate smoothly.
