【摘要】：对于直升机、航空发动机等旋转机械,需要在旋转侧与固定侧之间传输数据与电能,但数据与电能通常都是通过多个线圈分开各自传输的,这不仅影响系统传输的稳定性,同时还大大增加了系统的故障率。因此,数据与电能通过一个线圈进行传输对生产效率的提高有着重要的意义。本文将研究数据与电能在旋转机械上通过单一线圈进行传输的技术,在电能稳定传输的同时,数据信号也能够高质量的稳定传输。论文首先提出了可行的系统构成方案,设计出单线圈传输系统由电能传输通道、信号耦合以及信号传输通道三部分组成的构架。然后,对松耦合变压器进行了理论建模和磁路分析。通过用Ansoft Maxwell电磁仿真软件进行3D静态磁场仿真,分析了气隙对其电能传输效率和数据传输可靠性的影响;同时,针对非接触电能传输的漏感补偿以及高频逆变拓扑结构进行了分析。提出了松耦合双谐振回路模型,并进行相关的理论研究,得到非接触电能传输最大功率传输的条件;再次,文章对电能传输通道进行了研究,主要是对通道电路进行了设计。最后,通过设计复合式的耦合电路解决了高压电能信号与高频载波小信号的耦合与分离问题,同时设计了基于BFSK的调制电路和CD4046的锁相环鉴频解调电路以及检波电路。通过实验平台的搭建,进行了数据与电能单线圈传输实验,结果表明:基带信号经过调制,经耦合电路注入电能传输通道,电能与信号通过一个线圈进行传输后,能经过耦合电路成功的分离,并通过解调复原出基带信号。
[Abstract]:For helicopter, aeroengine and other rotating machinery, it is necessary to transfer data and electricity between the rotating side and the fixed side, but the data and electric energy are usually transmitted separately through multiple coils. This not only affects the stability of the system transmission, but also greatly increases the failure rate of the system. The transmission of data and electric energy through a single coil is of great significance to the improvement of production efficiency. This paper will study the technology of data and electric energy transmission through a single coil in rotating machinery. At the same time, the data signal can be transmitted stably with high quality. Firstly, a feasible system scheme is put forward, and the single coil transmission system is designed by the power transmission channel. Signal coupling and signal transmission channel three parts of the framework. Then. Theoretical modeling and magnetic circuit analysis of loosely coupled transformer are carried out, and 3D static magnetic field simulation is carried out by using Ansoft Maxwell electromagnetic simulation software. The influence of air gap on power transmission efficiency and data transmission reliability is analyzed. At the same time, the leakage inductance compensation and high frequency inverter topology of contactless power transmission are analyzed. A loosely coupled double resonant circuit model is proposed and related theoretical research is carried out. The conditions of maximum power transmission for contactless power transmission are obtained. Thirdly, the paper studies the power transmission channel, mainly the design of the channel circuit. Finally. The problem of coupling and separation between high voltage power signal and high frequency carrier signal is solved by designing compound coupling circuit. At the same time, the modulation circuit based on BFSK and the demodulation circuit and demodulation circuit of CD4046 phase-locked loop are designed. The results show that the baseband signal is modulated and injected into the power transmission channel through the coupling circuit. After the power and signal are transmitted through a coil, they can be separated successfully through the coupling circuit. The baseband signal is recovered by demodulation.
