[0002] Wireless charging system is divided into energy supply end, transmitting end, receiving end, energy receiving end, generally, data interaction contains transmitting end and receiving end data interaction, and energy supply end and energy demand end data interaction. But more cases are that energy supply end and energy demand end need to carry out data interaction. When the data of interaction needs to contain the data of transmitting end and receiving end, software transparent transmission mode is used to integrate the data of transmitting end and receiving end according to certain software protocol, and then data interaction is carried out, when the data of transmitting end and receiving end is not needed, hardware transparent transmission is used, to reduce the communication delay generated by data forwarding in the middle.

[0003] ASK modulation is a kind of analog modulation mode, with binary digital as signal, and sinusoidal wave as carrier wave. In 2ASK modulation, the amplitude of carrier wave has only two states, that is, the baseband rectangular pulse of digital information 0 or 1 is used to key control a continuous carrier wave, so that the carrier wave is output intermittently. When carrier wave is output, it represents sending 1, and when there is no carrier wave output, it represents 0.

[0004] 2ASK demodulation is divided into coherent demodulation method and envelope detection method. Coherent demodulation is to provide a coherent carrier wave with the same frequency and phase as the carrier wave of transmitting end at receiving end, and the circuit implementation is complex; envelope detection does not need coherent carrier wave, and the signal can be restored after rectification and filtering, and the circuit is simple.
