Abstract

The invention discloses an indoor LED lamp array arrangement method integrating lighting and communication reliability. The method includes the steps that a three-dimensional space model is built according to indoor space parameters; a target function to be optimized is solved to optimize the arrangement position of an LED lamp array on a ceiling plane, wherein the target function to be optimized is linear combination of illuminance E (x,y) of any point (x,y) and the signal error rate BER (x,y) of any point (x,y) on a set receiver plane. On the situation that the illuminance requirement of the receiver plane and the signal error rate requirement of a visible light communication system are met, the target function is solved, a minimum value of the target function is solved, and accordingly an optimal layout optimization parameter result of the LED lamp array is obtained. The achievement method is simple and easy to achieve. The indoor LED lamp array arrangement method solves the problem that an existing visible light communication system cannot simultaneously meet the uniformity requirement of indoor illuminance and communication reliability of corners indoors.

Description

technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a method for arranging an indoor LED lamp array that takes into account both illumination and communication reliability. Background technique [0002] Indoor visible light communication is a communication method that can take into account both indoor lighting and communication purposes, and will become an important method of indoor wireless communication in the future. At the same time, under the premise of considering energy saving and consumption reduction, LED lights have become the first choice for accessing indoor visible light communication systems. In the indoor visible light communication scenario, the system must meet the requirements of both indoor illumination and communication reliability. From the perspective of indoor illuminance requirements, for ordinary indoor environments (including living rooms, offices, factories, classrooms, etc.)...
