[Abstract]:Wireless energy transmission technology has been commercialized in many fields, such as human implanted devices, wireless sensor networks and other applications, it is often necessary to transmit signals at the same time, in order to transfer control instructions. Feedback system states and so on, which has practical application significance. This subject adopts double resonant coupling structure, this structure can provide two separate frequency bands for energy transmission and signal transmission respectively. On the basis of guaranteeing the performance of energy transmission, the fast data transmission rate is realized. Firstly, according to the theory of wireless energy transmission and near-field magnetic communication technology, the power and efficiency of energy transmission, the power response time and bandwidth of signal transmission are taken as the main parameters to measure the transmission performance in this paper. The relationship between these parameters and circuit quality factor Q is analyzed. Secondly, the concept of equivalent inductance is put forward, which is used to calculate the bandwidth and response time of double resonant circuit. The transmission factor is used instead of the quality factor as the parameter to measure the energy and signal transmission performance of the double resonant circuit. The conclusion that the parallel coil is more suitable as the coupling coil is analyzed. The capacitance and inductance in the double resonant circuit will directly affect the position of the two resonance points and the size of the transmission factor. It is the most important parameter in the design of the system. The mutual inductance coupling model is used to model the double resonant coupling structure, and the influence of the parameter change on the transmission performance is analyzed by mathematical calculation and circuit simulation. Thirdly, the hardware design of the whole transmission system is completed. The full-bridge inverter circuit is chosen as the energy excitation source, the Leeds wire winding coil is used, and the binary amplitude keying is used as the signal modulation scheme. Loading Scheme using Inductance Coupling as signal Finally, the experiment and analysis of the whole transmission system with dual resonant coupling structure are carried out. According to the energy transmission, the main analysis of the different transmission distance, different receiver load on the system output power and transmission efficiency in the load value is less than 10. The overall transmission efficiency above 70% can be realized when the transmission distance is less than 120mm. For signal transmission, the signal can be loaded effectively by inductive coupling, and the signal separation and modulation and demodulation can be realized by analysis without any influence on energy transmission. The response time of the system determines that the maximum data transmission rate can be achieved at a maximum data rate of 56kHz when the load is 1.31 mm and the distance is 122 mm.
