Wireless power transmission system and wireless power transmission control method

The invention provides a wireless power transmission system and a wireless power transmission control method, which can adjust communication rate of the system according to the change of load to improve anti-interference capability of the wireless power transmission system. A receiving end of the wireless power transmission system comprises an output power sampling module, which is used for collecting output power signals and sending the signals to a receiving end MCU; and the receiving end MCU judges change of power and generates a judgment signal, and sends the signal to a sending end MCU through a transmitter module and a wireless communication receiving module of a wireless communication module. The sending end MCU has a communication monitoring function, comprises a control module, and can judge whether the current communication rate ensures normal and stable working according to the power change fed back by the receiving end, and if the system communication is unstable, adjusts the communication rate ad
