Design And Implementation Of Passive Building Environment Detection System Based On Internet Of Things

Passive buildings are built based on passive design,which have excellent heat-insulating property and excellent air tightness achieved energy saving and environmental protection.The passive building is expected to develop rapidly in China.At the same time,the indoor environmental quality problems of passive buildings have attracted more and more attention.Aiming at the problem of passive building environmental detection,this study developed the design of environmental detection system based on Internet of things,which made the detection more convenient,the interface more friendly and the function more perfect.The main works are as follows:First of all,the passive technology of passive buildings,the requirements of environmental detection and the standard specifications of environmental detection are reviewed.Based on that,a series of low-power and high-precision embedded environment detection modules were developed to detect the temperature,humidity,illumination,PM2.5 and PM10 in passive buildings.Secondly,this design developed the SQL Server database and the Web terminal,established the B/S environment management platform of the Internet of things.The platform can classify,store and process the environment data collected by the environment detection module,and achieve the purpose of monitoring the environmental condition of the passive building.Through the analysis and processing of a large amount of data collected,it provides data support for the passive building environment control strategy,and saves the building energy consumption as much as possible under the condition of ensuring the comfortable environment.Finally,through the design and development of the mobile application,the information interaction between mobile terminal and Web terminal was implemented.The mobile phoneapplication based on Android system can manage user information and permissions,display indoor environment conditions in real time,and perform pop-up window reminder functions when indoor environmental conditions are in question.Mobile phone APP can greatly facilitate people to obtain environmental information,meet the perceived needs of people for the environment.Compared with previous environmental detection technology,the system is designed for passive buildings.The means of detection and transmission are simpler,data processing is more reasonable,information dissemination is more efficient,and users get environmental information more convenient.In practical applications,the environmental detection module in the system has low energy consumption and accurate detection,and the terminal management platform and mobile application are running normally.
