Scene type classroom intelligent illumination optimization method

Abstract

The invention provides a scene type classroom intelligent lighting optimization method, which comprises the following steps: firstly, determining an evaluation standard, establishing a dimming lighting distribution table of each desk test point in a classroom for a dimmable lamp group, and aiming at different lighting scenes such as self-repair, projection, blackboard-writing teaching, discussion,break-in-class and the like in the classroom, establishing a lighting distribution table of each desk test point; establishing a light color scoring function and an overall evaluation function of color temperature and illumination in each scene; then, after multi-objective optimization algorithm parameters and an individual coding strategy are initialized, performing iterative genetic evolution through heredity, crossover and mutation, obtaining a Pareto optimal solution set, and selecting a solution with the optimal overall evaluation function value as an output optimal solution; and transmitting the optimal solution to a lamp bank driver for dimming. The light color scoring function can be adjusted according to different learning activity scenes in the classroom, so that the optimized lighting condition can meet the requirements of different learning scenes, the pertinence of lighting control is improved, and a more humanized lighting environment is provided for classroom learning.

Description

[0001] This application is a divisional application with application number 201910287214.4, application date April 3, 2019, and invention name "scene-style classroom intelligent lighting system, control device, and optimization and control method". technical field [0002] The patent of the invention belongs to the field of intelligent lighting, and specifically relates to a scene-type classroom intelligent lighting optimization method. Background technique [0003] The school is a place for learning. The lighting should fully consider the sufficient illumination required for reading and writing. It is necessary to choose a suitable light source and design and / or combine a comfortable and natural lighting environment. The classroom is the place where students spend the longest time every day. Inappropriate lighting not only affects students' learning, but may also cause students to be short-sighted. In the past, the lighting in the classroom was generally only required to be...

[0008] Aiming at the influence of different lighting conditions on learning in the existing classroom lighting, the purpose of the present invention is to provide a scene-type classroom intelligent lighting optimization method. In the offline state, different driving currents of dimmable lamp groups in the classroom can be obtained through sample collection. Combine the color temperature and illuminance of each test point to establish a dimming lighting distribution table. When it is applied online, it can identify the current activity mode in the classroom based on the classroom image and human sensor signals, such as self-study, projection, blackboard teaching, discussion, and breaks. According to the characteristics of different activities, the light color scoring function of color temperature and illuminance is adjusted. Based on the scoring values ​​of the four factors of color temperature, illuminance, illuminance uniformity and energy saving, the multi-objective optimization algorithm is used to calculate the driving current value of each LED string of the dimmable lamp group. Optimizing, the optimization results are sent to the driver to change the light output of the lamp group, realizing intelligent lighting suitable for various learning activities in the classroom
