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

Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] In the existing 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 power failure. Loss of data, more serious cause power failure of the receiver, the stability and reliability of the system cannot be effectively guaranteed. Although the energy received wirelessly may not be enough to provide the normal working power of the receiver at a certain moment, but within a limited period of time, the overall energy received wirelessly is sufficient to provide the normal operation of the receiver during this period, that is, in Within a limited period of time, the average...

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.
