管道机器人无线发射装置磁场分布研究

Research on Magnetic Field Distribution of Wireless Transmitter for Pipeline Robot

针对管道机器人无线通信定位精度低和距离近的问题,提出一种管道机器人发射装置的并行多级线圈结构,提高空间中电磁线圈的磁场发射强度。利用ANSYS对不同匝数的单级线圈进行仿真,仿真结果表明在线圈激励电压一定的情况下,线圈产生的磁场的强度与线圈匝数无关;在符合技术等指标要求下,线圈的产生的场强大小与线圈的级数成正比关系。

To the low accuracy and close distance problems of pipeline robot localization, a sort of multiple parallel coilmodel in the pipeline robot emitter is presented, which can improve the density of magnetic field stimulated by the emitter.The ANSYS sottware is used to simulate different number of turns of the single coil. Simulation result shows that under thecircumstance that the excitation voltage is given, the density of the magnetic field generated by the coil has nothing to do withthe turns. In accordance with the technology parameters, the density of magnetic field is proportional to the series of the coil.
