With the deepening of the problem of population aging,home-based pension has become the main mode of pension.The indoor light environment of buildings is an important part of the living environment of the elderly.With the change of age and physical health,their cognitive and expressive abilities,learning and using abilities of intelligent devices are gradually decreasing,while their demand and dependence on care from others and new intelligent devices are constantly increasing.This paper investigates and studies the indoor lighting environment of urban residents in Beijing,Tianjin and Hebei,and introduces artificial intelligence technology into the control process of the lighting environment of the old people’s buildings.It actively identifies,perceives and predicts the lighting environment,visual comfort and aspirations of the old people,so as to make the lighting environment of the building actively adapt to the needs of home-based pension.Firstly,through literature reading and research,this paper makes an analysis and Research on the related theories and standards of the visual system of the elderly and the light environment of buildings;at the same time,by means of questionnaire survey and on-site testing,it investigates the present situation of the indoor light environment of existing residential buildings and the subjective evaluation feelings of the occupants in residential buildings,and carries out statistical analysis on the collected data,and obtains the daily life of different users.Under the conditions of home life,the relationship between indoor light environment evaluation factors and light environment satisfaction was analyzed by age discrimination,and the light environment satisfaction data for the characteristics of the elderly were obtained.Secondly,using the method of artificial intelligence and using the software of matlab,three kinds of prediction models of indoor light environment satisfaction of buildings,such as Softmax regression model,BP neural network and random forest,are established and trained,and the required indoor light environment model is obtained.Thirdly,the intelligent light environment test and evaluation system is constructed by using intelligent model,and the basic elements of indoor light environment are adjusted to suit the living and life of the elderly,so as to realize the intelligent control of building light environment which meets the needs of the elderly actively,and thescheme of active control system for the light environment of the bedroom,living room and kitchen of the elderly is given.In this paper,through the analysis and study of the indoor light environment of aging buildings,the influencing factors of the evaluation of indoor light environment of buildings are mastered,and the artificial intelligence model is established.Intelligent model is used to construct intelligent building light environment test and evaluation system and control system,which can provide suggestions and guidance for future aging indoor light environment design. |
