Abstract

The invention relates to the visible light communication, the indoor visible light illumination, the indoor plastic optical fiber communication and the indoor plastic optical fiber illumination fields, and more particularly to a light source arranging method for an indoor visible light communication system. The method comprises: establishing a three-dimensional model based on the indoor spatial parameters; and calculating the light source power at each position of the entire ceiling plane by minimizing the variance of the received plane signal-to-noise ratio to ensure the indoor reliable and uniform communication quality and ensure that the illumination plane satisfies the minimum illumination intensity standard. According to the calculation result, the light source is divided into two types and the commercial LED light source with the corresponding emission power is arranged as the main light in the first type light source position, and a part of the light emitted from the LED light source is optically coupled into the plastic optical fiber through an optical device and is guided to the second type light source position as a secondary light source, therefore achieving indoor visible light communication and illumination combined by the LED and plastic optical fiber. The method can be performed simply, and at a low cost, the reliability and the uniformity of the communication quality are ensured, delivering the goal of conserving energy.

Description

technical field [0001] The present invention relates to the fields of indoor visible light communication, indoor visible light lighting, indoor plastic optical fiber communication and indoor plastic optical fiber lighting, and in particular relates to a light source arrangement method for an indoor visible light communication system. Background technique [0002] Energy-saving LED technology has become the first choice for indoor lighting facilities, and LED-based visible light communication, as an additional function on indoor lighting facilities, has the advantages of energy saving and environmental protection, not occupying scarce wireless spectrum resources, and good information confidentiality. , has become a research hotspot in the field of communication in recent years. On the other hand, plastic optical fiber is cheap, lightweight, has a large core diameter, good flexibility, and has many advantages such as anti-electromagnetic interference and high bandwidth. It has...
