Research And Design Of Indoor Air Quality Detection System Based On Java

With the rapid development of the society,the problems of environmental are gradually highlighted,more and more people began to focus on environmental problems of home and studio.Especially the indoor environment of people's life,work and study but also aroused strong concern from all walks of life,On-line testing of the indoor environment can quickly understand the status of indoor air.Usually,if people chronically in a various environmental parameters which was below or above the standard prescribed by the state,the physical and mental health will have a negative impact.Due to the limited degree of human perception,if people were in a poor quality of the environment for a long time,and not felt the subtle changes of the environment in a timely manner.In order to practice the national "The 13 th Five-Year Plan" on the improvement and protection of people's livelihood ideas,over the past year,the living standards of our people have been significantly improved,while people are getting higher and higher demands about living environment,followed by giving impetus to the development of the home improvement industry.The most concern thing of user and decoration company was the indoor air quality problems after decorating.So we studied and designed a set of intelligent detection system according to the users' needs to detect the small changes of the environmental quality.So people can detect the kinds of parameters of the information according to the equipment and make appropriate measures,such as ventilation,cooling and other measures to improve the current environmental conditions.Based on the above problems of the environment,this paper mainly studied and designed the air quality detection system in the aspect of hardware and software which based on Java.The main function of the hardware platform was to collect the temperature and humidity,carbon dioxide,formaldehyde,PM2.5 and light intensity which was in the room,and the collected data uploaded to the host computer software,but also to perform the control commands from the host computer,Such as to control the curtains and windows open and close.The master chip of the hardware platform was the STM32F103ZET6 controller which was based on STM32 series,and SIM900 A which was integrated with GSM and GPRS for the wireless communication module.The design of the Web side and the Android side of the software platform were based on the Java language.Which the development of the Web side using MyEclipse + Tomcat6.0program development environment to build,Android mobile client development using Eclipse +ADT program development environment to build,the design and development of the Android application and Web page was based on the above environment.We use the MySQL database to store the indoor environment parameters which was from the lower computer in the data storage.We use the Socket communicate in the system of communication.Therefore,based on the above analysis of software and hardware,designed and developed a set system of user-friendly to inspect the quality of indoor air.Environmental testing system can not only help people to understand the merits of the indoor environment,but also can promote the research and development of the environment in some degree.At the same time,according to the national “The 13 th Five-Year Plan” requirements,it has important value and significance to adhering to the green,innovation and coordinated development,and promote the development of environment-friendly and environment-harmonious.
