Embodiment Construction

[0196] The invention discloses a method for co-transmitting information and energy in a visible light communication system.

[0197] refer to figure 1 , is a schematic workflow diagram of a method for co-transmitting information and energy in a visible light communication system provided in this embodiment, including the following steps:

[0198] Step 1: Establish a point-to-point SLIPT VLC system. The point-to-point SLIPT VLC system includes a point-to-point transmitter and a point-to-point receiver. The point-to-point transmitter converts the point-to-point transmission signal into visible light through a light-emitting diode and sends it to the point-to-point receiver;

[0199] The point-to-point receiver receives visible light through photodiodes for point-to-point information reception, or uses visible light through solar panels for point-to-point energy collection; that is, the point-to-point transmitter has only one light-emitting diode, and can send point-to-point transm...

Abstract

The embodiment of the invention discloses a method for jointly transmitting information and energy in a visible light communication system. The method comprises: establishing a point-to-point SLIPT VLC system, and a point-to-point transmitting end converts a point-to-point transmission signal into visible light through a light emitting diode and sends the visible light to a point-to-point receiving end; and the point-to-point receiving end carries out point-to-point information receiving on visible light through a photodiode, or carries out point-to-point energy collection through a solar cellpanel. By the adoption of the method, three key performance indexes, namely illumination, information transmission and energy collection, of the SLIPT VLC system can be analyzed at the same time.

Description

technical field [0001] The present application relates to the field of visible light communication, and in particular to a method for simultaneous lightwave information and power transfer (SLIPT) in a visible light communication (visible light Communication, VLC) system. Background technique [0002] The explosive increase of wireless devices and the increasing demand for high-speed data services have brought enormous pressure to traditional wireless communication networks, including but not limited to radio frequency (radio frequency, RF) crisis and rapid battery depletion. To solve this problem, the simultaneous lightwave information and power transfer (SLIPT) technology in the visible light communication (visible light communication, VLC) system is characterized by its huge license-free spectrum, no electromagnetic interference, and good inherent security. And other characteristics become a promising technology of indoor wireless network. From the perspective of applicat...
