Research On Indoor Intelligent Lighting Control Strategy Combined With Natural Lighting

In recent years,the energy saving and intelligent effects of the lighting system have become better and better.The intelligent lighting control system can not only improve the quality of the light environment in the building,but also improve the comfort of the working environment of the people,and help the building Energy management and control.This article takes the office in a certain area as the research object,and proposes an intelligent lighting control strategy that combines natural lighting with artificial dimming.First,the basic knowledge of lighting and natural lighting is introduced.Taking an office in a certain area as an example,Ecotect Analysis software is used to build a model of an office building and analyze the climatic factors of building lighting and the building’s own factors,and analyze and study indoor lighting characteristics.Secondly,using DIALux evo to simulate the illuminance of the indoor working surface at different times of the day under different sky models in the direction of the room depth and parallel to the side windows Lighting characteristics with uneven illumination in different directions.Therefore,when designing a lighting control strategy,the influence of windows on natural lighting needs to be considered to achieve uniformity of illuminance.Then,the improved particle swarm optimization algorithm is used to implement the lighting control strategy.MATLAB is used to build a model based on this algorithm and perform simulation calculations.Whether in partition or split-point control applications,it can well reduce the uneven phenomenon affected by the window.,So that all working surfaces in the room can achieve the purpose of having a constant standard illuminance.After simulation calculation,and taking an office building as an example,the total energy consumption generated by the traditional lighting control method in the building is compared with the total energy consumption generated by the control strategy in this paper,and finally proves that this strategy and algorithm are feasible.Finally,in order to verify the above control strategy,a design of office lighting control system based on natural lighting was designed.Realized the design of the overall structure of the system and the hardware design of the master control unit and slave control unit.The hardware design includes the controller design,power supply module,stepper motor drive,lamp dimming drive,etc.;on the basis of the hardware,the corresponding The software design,including the master-slave control unit main program,the communication between the main controller and the host computer,stepper motor drive,dimming data processing and other program design ideas and processes,combined with the improved particle swarm in Chapter 5 can only be adjusted Light strategy to realize the adjustment of indoor lamps and curtains combined with natural light.Finally,the intelligent lighting control circuit was realized and the experimental model designed for this subject was demonstrated,and the feasibility of the control strategy was verified.
