A method of wireless transmission of electricity is disclosed, including: inputting a first AC electricity into a transmitting terminal intermittently, and generating, by a microcontroller unit, different control signals according to the intermittently input first AC electricity; modulating the control signals and a first constant-voltage DC electricity to an electrical signal transmitted through a wire; performing a signal-electricity separation process to the electrical signal, to separate the control signals from the electrical signal; generating, by a signal generator, a near field inductive signal, and modulating the near field inductive signal and the control signals, to generate a signal to be sent; and amplifying the power of the signal to be sent, and sending, by a transmitting coil, the power-amplified signal to be sent in the form of an electromagnetic wave. The present invention can convert the DC electric energy into electromagnetic waves required by near field electromagnetic induction, generate different control signals according to the intermittently power supply of the transmitting terminal, and use the control signals to modulate the electromagnetic waves, so that the wireless electric power transmission and one-way control signal transmission can be achieved at the same time, and it can provide normal power supply to the load while controlling the operating mode of the load.
