Intelligent Control Method of Indoor Physical Environment in Atrium Under Social Information Network

In order to meet the needs of human body for indoor environment, an intelligent control method of indoor physical environment in atrium under social information network is proposed. Considering the fluid dynamic characteristics of the building atrium, the physical environment model of the building atrium is constructed. Use social information network to collect physical environment parameters such as temperature and humidity. Set the environment intelligent control target according to the thermal comfort of human body. The intelligent controller of indoor physical environment is designed by combining fuzzy control and PID control. With the support of control commands, the intelligent control task of indoor physical environment in the atrium of the building is realized. Through the performance test experiment, it is concluded that compared with the traditional control method, the control errors of indoor ambient temperature, humidity and daylighting coefficient are reduced by 0.61℃, 0.51% and 0.145 respectively, while the control error of sound pressure is reduced.
