Abstract

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 terminal enters a sleeping state. The wireless power transmission system uses the sensing signal of the proximity sensor as a main criterion, so that the system power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless energy control transmission control, and relates to a sleep control method and a wake-up control method of a wireless power transmission system, that is, a wireless power transmission system wake-up sleep composite control method. Background technique [0002] In recent years, wireless charging technology has developed rapidly. Because of its non-contact, wire-free connection, and convenient operation, it has attracted the attention of various manufacturers, and various wireless charging products have also come out one after another. On the whole, a complete wireless charging system includes two parts: a wireless energy transmitter and a wireless energy receiver, and the wireless energy transmitter and the wireless energy receiver transmit energy through a magnetic field, and there is no wire connection between the two. When the receiver device is removed, the transmitter should immediately stop ...
