感应耦合电能传输系统中信号传输技术研究
|
摘要
感应耦合电能传输(Inductive Coupled Power Transfer,简称ICPT)技术为非接触能量传输提供了一种新的途径。近几年,该技术的应用有了很多成功的案例,展示了其广阔的应用前景。然而很多实际应用系统不仅要求非接触传输电能,还要求非接触传输信号,因此就需要在ICPT系统中实现信号的非接触式传输。
论文以国家自然科学基金项目“高效多自由度非接触电能传输系统关键技术研究”(50777071)和某国有大型企业横向合作项目“×××感应式电能与信号耦合传输装置研发”为背景,在课题组以往对感应耦合电能传输技术研究基础上,主要研究了ICPT系统中信号传输问题。
论文首先介绍了ICPT系统中信号传输技术的国内外研究现状、课题研究目的及意义等,给出了ICPT系统中实现信号传输两种方法的基本结构和原理。
然后,论文对第一种实现方法进行了研究,该方法是基于电磁感应原理,通过在ICPT系统电磁耦合机构中增加一对信号传输线圈实现信号传输。采用二进制频移键控调制方式,将调制后的信号加载到信号发送线圈上产生交变磁场,信号接收线圈在该交变磁场中产生感应电压,再经过滤波、解调等处理后实现信号的有效传输。论文给出了电磁耦合机构中线圈布局设计,着重分析了电能传输对信号传输的影响,提出了信号线圈大小设计原则,在此基础上进行了信号传输环节电路设计,并通过了实验验证。
最后,论文对第二种实现方法进行了研究。该方法是基于电能波调制的信号传输方法,在ICPT系统中增加信号调制开关,根据被传输信号特征调节系统注入能量,在电能耦合线圈间形成综合能量信息流,电能接收端在接受电能的同时提取信号特征并进行信号复原,论文给出了该方法的基本原理,分析了系统的工作模态,并通过实验验证了该方法的可行性。
Inductive Coupled Power Transfer (ICPT) Technology provides a new way for contactless power transmission. In recent years, there were many successful cases in the applications of the ICPT technology, this technology demonstrates broad application prospects. However many practical application systems do not only require contactless power transmission, but also require contactless signal transmission. Therefore practical systems need to transmit signal based on ICPT system.
This paper based on national natural Science foundation“Research on key technology of efficient contactless power transfer system with multi-degree freedom and thorizontal cooperation projects“×××inductive coupling power and signal transmission device research and development”with a large state-owned corporation, it mainly focuses on the signal and power transmission in ICPT system based on the group’s research on the Inductive Coupled Power Transfer.
Firstly, this paper introduced the research status of the Inductive Coupled Power and Signal Transfer technology in and abroad, the research purpose and meaning, then proposed two methods for signal transmission based on ICPT system, and also gave the structure and principle of those two methods.
Secondly, this Paper put a embedded research on the first method. It is based on the principle of electromagnetic induction, achieved signal transmission by adding a pair of signal coils to the electromagnetic structure of the ICPT system .This method used the frequency shift keying which has a strong anti-interference ability, loading the modulated signal to the signal sending coil to generate alternating magnetic field, the signal receiving coil induced voltage in this magnetic field, realized signal transmission after demodulation and other treatments. This paper proposed a arrangement design of electromagnetic structure for the system, put a emphasis on the interference of the power transmission to the signal transmission, proposed the design principle for the signal coils, then designed the signal transmission link,and verified by the experiment
Finally, this Paper researched on the second method. This method is based on the power waveform modulation, it injected the power to the system according to the signal character transmitted by adding signal modulation switch, forming the integrated energy and information flow in the coupling windings of the system. The receiver of system received the power, and extracted the characteristics of the signal and recovered the signal at the same time. In this paper, the basic theory and mode of the system was analyzed and verified by the experiment.
