| The industrial civilization has developed continuously and the rhythm of modernization construction is much quicker, which has caused a large amounts of environmental pollution problems. Especially in recent years, the domestic environmental pollution, particularly air pollution has caused the great attention of people. Along with the development of IOT and the popularization of smart mobile terminal, we propose the combination of the two technology to build a system of air quality monitoring based on IOT.The air quality monitoring system is designed and implemented for ordinary personal user. Firstly,we research and analysis the domestic and international air quality monitoring situation, then we introduce the technology used in the realization of the system,which include the web of things technology,web service technology and the Android development technology. According to the three layers of this system which include the perception(sense) layer, network(GPRS,wifi) layer, application layer, we make the demand analysis. After this,we design the function module of system and the interactive process between server and the mobile phone terminal and their respective operation process. In the4th chapter, we describe the development of user interface and the main function modules in detail. Finally we have carried on the function test and performance test to the system. And we get the statistical data in the operation of this application.The innovation of this system is to meet the individual needs of air quality monitoring. Basing the key technology of the internet of things, users can not only get the air quality data from the Environmental Protection Bureau,but also can get their individual air quality information by placing the Air quality monitoring device in different places according to their own needs. This fully embodies the advantages of the combination of IoT and the mobile Internet. From this, we can correctly predict that the integration of these two technologies will play an extra important role in the environmental monitoring in the coming days. |
