Design And Implementation Of The Mobile Monitoring System For Water Environment

In the process of rapid development of society,human beings have caused serious pollution and destruction of water resources.In recent years,the pollution source online monitoring system has been widely installed in many cities,but water pollution accidents occured frequently,the environmental situation is still not optimistic in China.The problems exposed in the on-line monitoring system of pollution sources indicate that the fixed-point on-line monitoring network has been unable to meet the actual needs,especially for sudden?hidden and remote water pollution incidents,can not be fixed monitoring.According to the actual demand,this paper designs and implements the water environment mobile monitoring system.In the demand analysis,this paper presents the use case model,using the use case diagram and the use case scenario in the UML specification to clarify the user's needs.In the summary design,the physical topology network model,the domain model,the system sequence diagram and the database logic of the mobile monitoring system are designed and the overall architecture and core functions of the system are defined.In the detailed design and implementation,the time series model of the mobile monitoring system is designed,and the core business module of the system is explained more clearly by using the timing diagram and class diagram.The whole system uses C/S architecture,the client uses Android application development technology?vacuum inspection tube-electronic colorimetric technology and sensor technology,the server uses java web development technology.The main functions of the system include:1.Data acquisition and analysis: the main completion of the system acquisition and analysis work,including sample testing,upload results,local records,electronic maps,camera sampling,networking analysis.2.Key data management: the main completion of the system and sample detection related to key data management,including the system to view real-time detection data,historical test data,early warning test data and the corresponding analysis and detection points marked.3.Auxiliary data management: the main completion of the system to detect data related to the auxiliary data management,including the standard library data management,testing parameter management,user information management,administrator personal information management.The system is a practical project,able to meet customer needs,the application of the system on the one hand can be simple and fast,intelligent and accurate to complete the complex environment of water quality testing;the other hand,the test results can be quickly uploaded to the server remote management side,is conducive to the relevant managers to make more Accurate choice,so that the corresponding reasonable prevention or prevention program in a relatively short period of time to develop.
