Audio playing method, system and equipment based on simultaneous information and energy transmission, and storage medium

Abstract

The invention provides an audio playing method, a system and equipment based on simultaneous information and energy transmission and a storage medium. The method comprises the following steps: a first wireless terminal scans surrounding second wireless terminals, builds a communication link with at least one second wireless terminal responding to the first wireless terminal, and provides energy for the second wireless terminals; the first wireless terminal performs segmented analysis on an audio file to be sent to obtain energy required for playing each audio paragraph by playing equipment of the second wireless terminal, and the energy is used as playing energy of the matched audio paragraph; and the first wireless terminal allocates a corresponding information signal subcarrier number based on the audio paragraph, allocates a corresponding energy signal subcarrier number based on the playing energy corresponding to the audio paragraph, generates an information signal and an energy signal respectively, and wirelessly sends the information signal and the energy signal to the second wireless terminal. According to the wireless terminal, audio playing can be carried out through simultaneous information and energy transmission under the condition that no battery exists, the battery of the wireless terminal is removed, and the overall weight of the wireless terminal is reduced.

Description

technical field [0001] The present invention relates to the field of audio playback, in particular to an audio playback method, system, device and storage medium based on signal energy simultaneous interpretation. Background technique [0002] When the destination node or relay has no fixed or stable energy source, the node can also obtain energy by collecting the radio frequency signal sent by the source, that is, wireless energy harvesting technology, which improves the energy efficiency of network transmission and prolongs the wireless network. The life span has been widely concerned by scholars. The nodes can perform corresponding wireless energy collection and information decoding operations on the signals that transmit energy and information, and can realize simultaneous transmission of information and energy, referred to as simultaneous transmission of information and energy.
