Mobile self-adaption energy and information synchronization wireless transmission method and transmission device

Abstract

The invention discloses a mobile self-adaption energy and information synchronization wireless transmission method which comprises the following steps: Step 1, an embedded MCU generates a combination frequency signal; Step 2, the combination frequency signal is coupled to a wireless strong coupling type bilateral matching receiving coil; Step 3, an optimal frequency estimation circuit estimates a resonance oscillation frequency point; when the frequency of a frequency synthesizer is stabilized, the Step 4 is carried out; Step 4, the embedded MCU generates an information sequence, and a frequency-selecting switch controls signal output; Step 5, according to the amplitude of fluctuation of a DC signal, the situation that whether a device enters a restarting mode or not is determined; Step 6, when the amplitude of fluctuation of the DC signal is smaller than the reference level offset, the device enters the restarting mode. The invention further discloses a device for realizing the mobile self-adaption energy and information synchronization wireless transmission method. The device comprises an energy and information wireless launching unit and an energy and information wireless receiving and recovery unit connected with each other and has the advantages of high efficiency and reliability.
