Awakening and sleeping control methods for wireless power transmission system

The invention provides an awakening control method and a sleeping control method for a wireless power transmission system. When a wireless power receiving terminal approaches a wireless power transmitting terminal, a proximity sensor sends a sensing signal and the signal is transmitted to an I/O interface of a transmitting terminal MCU, and then the level of the interface hops; the transmitting terminal MCU sends a PWM drive signal to an inverter circuit for working; and the wireless power transmitting terminal is awaken. When the transmitting terminal MCU detects hopping of the level of the I/O interface connected with the proximity sensor, communication between the wireless power transmitting terminal and a wireless power receiving terminal is interrupted, or the frequency of sending a PWM drive signal by the transmitting terminal MCU reaches a set frequency threshold value, the transmitting terminal MCU stops sending of the PWM drive signal to the inversion circuit and the wireless power transmitting termi
