Design And Implementation Of Client For Indoor Environmental Monitoring System

With the advent of the enlarged health age, people’s concern about health care hasgradually improved, especially for the requirement on indoor environmental quality isstricter. In people’s lifetime people spend most of time indoor, it’s very important forpeople to make a good indoor environment. Therefore indoors environment monitoring isvery necessary for people. At the same time with the rapid development of informationtechnology and mobile Internet, which make it possible to get information anytime andanywhere, and put forward the requirement of the traditional environmental monitoringsystem more intelligent, more efficient and more friendly. Therefore establishing anintelligent, efficient, friendly client based on environmental monitoring system emerge asthe times require.This paper presents a set of intelligent and efficient client in indoor environmentalmonitoring system, which includes PC client and Android client. Firstly, this paperintroduces the general frame of monitoring platform, including structure of platform anddata processing flow of client. Then PC client and Android client are described in detail. InPC client this paper mainly introduces the following aspects: historical data can be queryby comparing query efficiency between mechanism of Hibernate cache and JDBC, amulti-function alarming can be worked in real-time by data source module, informationprocess module and alarm strategy module, to optimize the concurrency control, in frontend of PC client by using asynchronous request of Ajax to reduce data of reloading thepage, in background a static region can be establish; by drawing different kinds of curvesto make the interface friendly. In Android client this paper mainly introduces the followingaspects: data communication between Android platform and server, data communication inplatform of Android client, and mechanism of data storage in Android client; alarming inAndroid platform and monitoring the alarm information from server by using Servicecomponent, and real time curve drawing in Android client. This paper implements PC client and Android client in indoor environmentalmonitoring system. Combination of information technology and mobile Internettechnology makes the indoor environmental monitoring more intelligent, more efficientand more friendly. The client plays an important significance role in improving monitoringefficiency, saving the time for the operator.
