Research On Home Intelligent Health Environment Control System

In recent years,with the continuous development of social economy and science and technology,the level of industrialization is rapidly increasing,and the environmental pollution has become a serious problem.At the same time,the urban indoor environment has been polluted by various chemical and biological factors due to indoor decoration and decline of outdoor air quality.As a result,indoor air pollution is even worse than outdoor.Furthermore,most of us are basically in the indoor environment for study or work.Therefore,our requirements for indoor environment,especially the health and comfort of the family living environment,are becoming higher.At present,the Internet of Things technology is developing rapidly,and intelligent control technology is also rapidly applied to the control of the home environment.Therefore,the research on the home health environment control system has become particularly urgent.Based on the wireless communication technology of the Internet of things and the principle of information fusion,this thesis studies the construction and control methods of home health environment.In this thesis,family intelligent health environment control system based on Internet of things technology is designed,which is convenient,practical and low-cost.Not only the real-time detection and control of family environment parameters are realized,but also the human comfort and air quality of indoor environment are improved.The main research content of this article includes the following aspects.1.Firstly,the research background and significance of the subject were summarized,and the current situation of indoor environmental control methods and human comfort at home and abroad were investigated.Then,the thesis analyzed the evaluation methods and adjustment methods of factors affecting indoor health environment,and thus proposed the demand for home intelligent health environment system.2.For the environmental control system,this thesis analyzed the functional requirements and designed the home intelligent health environment system architecture based on the Internet of Things and Wi Fi communication mode for communication.3.For home intelligent health environment control system,the software and hardware design and communication protocol design were carried out.This thesis provided indoor environmental parameter detection equipment and environmental control equipment with single-chip microcomputer as the control core,in terms of communication,the communication protocol between each device and the home environment controller is designed,and the information interaction and control between the home environment controller and each device are finally realized.4.Aiming at the existing family environment control system,a set of healthy environment control scheme is put forward in this thesis.In this scheme,the fuzzy reasoning algorithm is used to detect the parameters of environmental quality index by using the health environment system,and the fuzzy control model is established.The control system realizes the intelligent control decision through the software,and sends the WIFI command to control the corresponding controller,and finally realizes the control of the indoor health environment indicators.In order to control the indoor health environment indexes,three closed-loop control schemes are designed to control the thermal and humid environment,light environment and indoor air quality respectively.This thesis implements the design of a family intelligent health environment control system that can make the indoor environment reach health indicators through intelligent control,which enhances people's living experience.
