Abstract

The invention discloses a wireless energy and data synchronous transmission system and a parameter acquisition method thereof, and belongs to the technical field of wireless electric energy transmission, and solves the problems that the volume is large and the error rate is increased along with the increase of transmission power existing in an existing wireless energy and data synchronous transmission scheme. A data signal to be transmitted serves as a modulating signal, and a high-frequency alternating-current voltage signal serves as a carrier signal. The modulating signal is adopted for modulating the carrier signal so as to obtain a modulated signal carried with data. The modulated signal is superposed onto an energy signal to be transmitted so as to obtain a superposed signal. The superposed signal is wirelessly transmitted to a secondary side circuit from a primary side circuit through a loose coupling transformer. The superposed signal transmitted to the secondary side circuit is separated into a modulated signal and an energy signal. The separated modulated signal is demodulated into a data signal. The system is applicable for wireless synchronous transmission of energy and data.

Description

technical field [0001] The invention relates to an energy and data synchronous transmission system and a parameter acquisition method thereof, belonging to the technical field of wireless energy transmission. Background technique [0002] The existing wireless energy and data synchronous transmission schemes are mainly divided into the following four types: [0003] Solution 1. Wireless power transmission system + radio frequency communication module: This solution introduces wireless communication modules based on the existing wireless power transmission system, such as ZigBee modules, Bluetooth modules and Wi-Fi modules, etc., to achieve wireless synchronization of energy and data transmission. However, this solution has two main problems: [0004] 1. Due to the additional introduction of wireless communication modules, the volume of the system increases and the cost increases; [0005] 2. The impact of energy transmission on data transmission increases with the increas...
