Design And Implementation Of Indoor Air Environment Monitoring System For Stadiums Based On Android Platform

With the rapid development of the national fitness cause,the number of people taking part in physical exercise in China has increased significantly,and the serious problem of outdoor haze has made more and more people choose to carry out fitness activities in indoor places,and the indoor air environment of good stadiums is an effective guarantee for the healthy movement of sports people.The traditional indoor environmental monitoring system has some drawbacks,such as poor real-time,narrow regional and large limitation,the sports stadium belongs to the tall space,which has the characteristics of large volume,dense personnel,and its particularity and function are different from the general building,which requires that its monitoring should be both systematic and comprehensive and accurate,Therefore,the environmental monitoring means of many general buildings do not apply to the monitoring of indoor environment of stadiums and stadiums.In this context,the development of indoor air environment monitoring system for sports venues based on Android platform is carried out in this paper.The system consists of environmental parameter acquisition equipment,cloud server side and mobile phone APP,which is designed by the combination of B/S and C/s network architecture,the cloud server side uses MySQL database with Java and Tomcat to form a good operating environment,the use of MVC design model and SSH framework for development,Through the UDP protocol,HTTP protocol and NB-IOT Technology,the data interaction with the acquisition device terminal and the mobile phone APP side is realized.The system has completed the development of functional modules such as indoor air environment monitoring,sports stadium information management and user information management,and realized the real-time collection and display of indoor environmental parameters(temperature,humidity,wind speed,carbon dioxide,fine particulate matter,total volatile organic compounds and formaldehyde).Mobile APP users can choose through GPRS data traffic or WIFI network communication,from the cloud server side to obtain sports venues environmental parameters and indoor air quality evaluation,and through the alarm function can see in real time whether the indoor air environment of stadiums meet the standards,in order to formulate and adjust the sports plan in time;The venue manager is able to take corresponding measures to improvethe environmental quality according to the environmental parameters and alarm function displayed by the mobile phone APP.The informationization,intelligentization and convenience of sports venues in practical application are realized.At the same time,a multi-layer security verification mechanism is also carried out on the security of the system,which effectively protects the user's personal information and ensures the safe operation of the system.The wireless monitoring of stadiums and gymnasiums through this system can not only check the indoor air environment parameters of stadiums and Gymnasiums in real time,but also the obtained big data can be used as the basic data screening for indoor environment evaluation of stadiums and gymnasiums,which can not only provide a reference for the establishment of the evaluation system of stadium monitoring system,but also provide a scientific basis for the establishment of indoor environment quality evaluation standards of stadiums and gymnasiums.
