Abstract
(EN)
Provided are a visible light energy-carrying communication system and method. The visible light energy-carrying communication system comprises a lighting facility end visible light energy-carrying communication system and a mobile client visible light energy-carrying communication system, wherein the mobile client visible light energy-carrying communication system at least comprises an information transmitting link, a signal collection module, a signal allocation module, an information receiving link and an energy collecting link. The visible light energy-carrying communication system and method of the present invention combine a visible light communication system with the wireless energy transmission technology together, and in accordance with the characteristics of the visible light communication system, an energy link is added to collect the energy carried by a visible light signal, so as to form a set of complete visible light energy-carrying communication system. The present invention combines the advantages of the visible light communication system, such as ultra-wide bandwidth, free frequency band, low power consumption of a transceiver, etc., and solves the problem that a mobile terminal relies on a power line by means of the wireless energy transmission technology, thereby realizing the simultaneous and wireless transmission of information and energy in practical significance.
