This article proposes and implements a long-range wireless power drive (WPD) system using a magnetic extender, which can be promisingly applied in underground pipeline transportations and in-pipe robots. Generally, the underground pipeline transportation networks usually rely on the power grid and control system to regulate the flow rate. Nonetheless, such wired pipeline networks mainly suffer from increasing the construction cost, maintenance difficulty, and system complexity. By using pulse frequency modulation, the development of the proposed long-range WPD enables a wireless pipeline network for flow rate regulation, which has the advantages of robust structure and reduced maintenance requirements. With the addition of a designed magnetic extender, the circuit network can offer an excellent fault tolerance capability for underground sensor-free WPD while maintaining a high transmission efficiency. Significantly, the use of a magnetic extender will cause no inconvenience thanks to its underground deployment. Accordingly, the system efficiency of a full-scale prototype can reach around 89.1% for the meter-range WPD. Theoretical analysis, computational simulation, and prototype experimentation are given to verify the feasibility of the proposed long-range WPD using a magnetic extender.

使用磁性扩展器的远程无线电源驱动器

本文提出并实现了一种使用磁性扩展器的远程无线电力驱动 (WPD) 系统,有望应用于地下管道运输和管道机器人。一般情况下,地下管道输送网络通常依靠电网和控制系统来调节流量。尽管如此,这种有线管网的主要问题是增加了建设成本、维护难度和系统复杂性。通过使用脉冲频率调制,所提出的远程 WPD 的开发实现了用于流量调节的无线管道网络,其具有坚固的结构和减少维护要求的优点。加上设计的磁性延长器,该电路网络可为地下无传感器WPD提供优异的容错能力,同时保持较高的传输效率。值得注意的是,由于其地下部署,使用磁性扩展器不会造成任何不便。因此,对于米级 WPD,全尺寸原型的系统效率可以达到 89.1% 左右。给出了理论分析、计算模拟和原型实验,以验证所提出的使用磁性扩展器的远程 WPD 的可行性。
