Research On Intelligent Control Algorithm For Indoor Lighting Control System

With the development of industrial civilization and enhancement of life quality, the demand for electricity is increasing day by day. The question of how to reduce the power consumption of indoor lighting has gradually become the focus of energy saving building study.This paper will focus on the subject of office indoor lighting, research for the rules of how nature light influence the indoor brightness, establish the mathematical model of indoor lighting laws, calculate the compensation of artificial lighting, and design the indoor lighting algorithms based on sunlight compensation. The main work about this paper is listed as followed:1. The establishment of mathematical model:According to the cyclical changes characteristic of the sun light, this paper proposes the calculation method of the direct sunlight, skylight, indoor and outdoor reflected light, establish the indoor natural illumination model.2. Compensation strategies:With the indoor natural illumination model, this paper proposes the calculation method of the artificial lighting devices, make uses of the sun light compensation strategies, and then maintain the indoor overall illumination at the baseline of the office space standard illumination recommended value.3. Algorithm design and implementation:Nowadays, daily life lighting adjustments is mainly controlled by hand-operated, therefore, the indoor environmental quality is not ideal, the energy-saving effect is not obvious. This paper makes a design of intelligent control algorithm based on sunlight compensation. It can make full use of the sunlight so that the artificial lighting brightness level can automatically adjust with the changes of the indoor nature light. The goal of the adjustment is to keep the working plane brightness at the baseline of the office space standard illumination recommended value. There is one separated thread in the real-time send-receive module which is specific to process the relevant calculation of the intelligent lighting control algorithm. This thread will startup in every ten minutes, calculate the indoor nature light illumination, obtain the adjustment of the relevant node, compare to the brightness level in the database, and make the final decision to adjust the indoor light source.4. Algorithm verification:There are a series of experiments in this section. To the results of these experiments, The Intelligent control algorithm of indoor lighting control system turned out to have a certain legitimacy and accuracy.Indoor lighting control strategies proposed in this article supposed to provide a new way of thinking which has explore a new method, improved the quality of luminous environment in Office lighting and saved energy, have good market prospects and good value.
