Abstract

The invention discloses a wireless energy and data synchronous transmission system based on inductive coupling and FSK modulation and a parameter design method thereof, and belongs to the technical field of the wireless electric energy transmission. The problem that the data transmission of the wireless energy and data synchronous transmission system based on multi-carrier communication is high inbit error rate and complex in data loading and circuit structure extraction under a high magnetic field is solved. The data carrier is generated by adopting a FSK modulation way; compared with the ASK modulation way, the interference resistance of the FSK modulation way is strong, and the anti-attenuation performance is good. The way of firstly adopting the inductive coupling comprises loading amodulated signal on a to-be-transmitted energy signal, and the way of inductive coupling is used for extracting the modulated signal which has been transmitted to a superposed signal of a secondary side circuit. Compared with the existing circuits of the data carrier signal loading circuit and the data carrier signal extraction signal based on the capacitance coupling, the circuit structures of the signal loading unit and the signal extraction units are relatively simple.

Description

technical field [0001] The invention relates to an energy and data synchronous transmission system and a parameter design method thereof, belonging to the technical field of wireless energy transmission. Background technique [0002] The existing wireless energy and data synchronous transmission methods based on magnetic field coupling are mainly divided into the following three types: [0003] The first one: directly modulate the power carrier by frequency shift keying (FSK) to realize data transmission from the power supply side to the load side, and realize reverse data transmission by load modulation keying (LSK). The power transmission and data transmission of this wireless energy and data synchronous transmission mode share the same group of coupling coils. However, since this method of synchronous transmission of wireless energy and data directly modulates the power carrier, the interference of data transmission on power transmission is large, so it is not suitable f...
