Design And Implementation Of Automatic Water Quality Monitoring System Software Based On Cloud Architecture

Our country’s research of water quality monitoring system starts later than thedeveloped countries, the current technology is far behind. Traditional water quality monitoring systems generally require manual observation site, even if they can be controlled by remote access, it’s hard to apply because of the development and application of high costs, poor flexibility and maintenance difficulties.According to the above shortcomings of traditional water quality monitoring system, MEMS center has developed a set of remote automatic water quality monitoring system based on cloud computing. And my main job is based on existing local water quality monitoring system, complete water quality monitoring system software based on cloud architecture, and joined the heavy metal concentration monitoring mechanism.Automatic water quality monitoring system software adopts the modularized design method, divided into cloud and local water quality monitoring system software. It is designed based on the mix architecture model of C/S and B/S of AJAX technology.Cloud water quality monitoring system software includes the design of the presentation, interface, business logic and data persistence layer. User interface is developed based on ExtJS framework. And cloud water quality monitoring system provides Web Service API. The stations upload the data though the API calls, and the cloud server will handle these data. This can be convenient to realize data sharing.Local water quality monitoring system software adopts C/S architecture design, and realizes heavy metal concentration monitoring, data storage and distribution. Using C#.net language development, it includes heavy metal concentration monitoring,3G wireless transmission and data synchronization communication.3G wireless transmission system was adopted to realize the real-time communication. This article also designed the two kinds of heterogeneous propagation algorithm for database replication to optimize the data transmission process and the system reliability.After completing the design, establishing the software platform and testing the functions, which include heavy metal concentration test, communications test, UI configuration and other functions. Through the test, the system can work normally.
