The embodiment of the invention discloses an energy-saving lighting optimization method and device for indoor visible light communication. The method comprises the steps: firstly, determining all parameters according to equipment hardware and environmental factors; correspondingly using each physical parameter as one element of an initial solution, and acquiring an initial solution set; performing p-optimality assessment on a target parameter corresponding to each initial solution in the initial solution set to obtain p-optimality evaluation values, and performing immune optimization calculation on the initial solution set according to the p-optimality evaluation values to obtain optimization results; and performing p-optimality evaluation on a target parameter corresponding to each solution in the optimization results, and using a solution with the minimum p-optimality evaluation value as the optimal solution to configure a corresponding physical parameter in an indoor visible light communication system. Through adoption of the embodiment of the invention, the physical parameter in the indoor visible light communication system can be reasonably configured to realize optimization of energy-saving lighting.
Description
technical field [0001] The invention relates to the technical field of visible light communication, in particular to an optimization method and device for energy-saving lighting in indoor visible light communication. Background technique [0002] Visible light communication technology has become a research hotspot in the field of communication in recent years. Visible light communication technology uses the bright and flickering of LED lights to couple information to LED lighting equipment to realize the organic combination of lighting and communication. It is an emerging wireless communication technology. In the visible light communication system, the light source not only plays the role of lighting , At the same time, data transmission can be carried out. Compared with traditional radio frequency communication technology, visible light communication technology has the advantages of safety, energy saving, good confidentiality, no need for spectrum certification, and high tr...
