Energy management method and system used for receiving end of information and energy simultaneous transfer system

Abstract

The invention discloses an energy management method and system used for the receiving end of an information and energy simultaneous transfer system. The method comprises steps of S1, starting a battery in order to supply power to the receiving end; S2, enabling the receiving end to receive and process an information and energy simultaneous transferring signal and acquire energy in the information and energy simultaneous transferring signal; S3, storing the acquired energy in a temporary energy storage unit; and S4, enabling the battery to stop supplying power and charging the battery with the energy stored in the temporary energy storage unit. The energy management system comprises a receiver and an energy management module. The method and the system, by controlling, storing and managing the energy received by the receiving end, overcomes a problem of instantaneous power supply insufficiency and unstable operation of a receiver caused by the receiving end of the information and energy simultaneous transfer system because of a time-dependent characteristic of a wireless signal, effectively guarantees stable operation of the receiver, and has good economic and social benefits.

Description

technical field [0001] The invention relates to the intersecting field of wireless communication technology and wireless power transmission technology, in particular to an energy management method and system at the receiving end of a signal energy simultaneous interpretation system. Background technique [0002] Simultaneous Wireless Information and Energy Transfer (Simultaneous Wireless Information and Energy Transfer), that is, the simultaneous transmission of information and energy through wireless means, is an emerging communication technology integrating wireless communication technology and wireless energy transfer technology. With the development of science and technology, the integration of energy technology and communication technology has become a trend. It can not only achieve high-speed and reliable communication, but also effectively alleviate the pressure of energy and spectrum scarcity. It has important application value in industry, medical treatment, and infr...

AI Technical Summary

Problems solved by technology

[0006] In the above-mentioned signal energy simultaneous interpretation system, if the wireless energy signal is directly rectified to supply power to the receiver, due to the time-varying nature of the wireless channel, the rectified output power is unstable, which may lead to unstable operation of the receiver or even data loss. Seriously lead to power failure of the receiver, the stability and reliability of the system cannot be effectively guaranteed, which affects the promotion and application of the simultaneous interpretation system
