Wireless electricity transmission method

The invention discloses a wireless electricity transmission method. The method comprises the steps: intermittently inputting first alternating-current power to a transmitting terminal, and generating different control signals according to the intermittent input of the first alternating-current power by virtue of a micro control unit; modulating each control signal and a first constant-voltage direct-current power to be an electric signal; carrying out the signal-electricity separation treatment according to the electric signal, and separating out the control signal; generating a near-field induction signal by virtue of a signal generator, modulating the near-field induction signal and the control signal, and generating a signal to be transmitted; amplifying the power of the signal to be transmitted, and transmitting the signal in an electromagnetic wave form by virtue of a transmitting coil. The direct-current power is converted to an electromagnetic wave needed by the near-field induction, the control signal is generated according to the intermittent power supply of the transmitting end, and the electromagnetic wave is modulated by utilizing the control signal, so that the control signal can be transmitted in a single direction while the wireless electric power is transmitted, and a working mode of a load can be controlled while the load is powered.
