固定线路机器人动态无线供电系统研究

Study on wireless power supply system for robot in fixed line

针对目前固定线路机器人采用有线供电或者更换电池方式的供电弊端,本文对固定线路机器人动态无线供电进行了研究。首先介绍了基于磁耦合谐振的固定线路机器人动态无线供电系统总体结构,提出了发射端线圈切换控制技术以及接收端不间断能量拾取技术。建立了运动过程中系统不同状态下一发一收和一发二收两种电路模型,并且以一发一收电路模型为例通过理论计算和有限元电磁仿真分析研究得出在发射线圈长度超过接收线圈长度之后,传输功率和效率都随着发射线圈的长度增加而降低,为发射线圈的长度优化设计以及系统的整体设计提供了参考。

Aiming at the drawbacks of robot in fixed line using wired power supply or battery replacement,this paper did research on dynamic wireless power supply. The overall structure of the system based on magnetic resonance is introduced. This paper also did research on the switching control technology of the emission coil and the uninterrupted energy picking technology. Established one-to-one and one-to-two circuits model of different states in motion. To one-to-one circuit model as an example,through theoretical calculation and simulation analysis,the result showed that the length of the emission coil impacted on mutual inductance and the whole system. This paper provided a reference to optimizing design of the transmitter coil.
