Research And Realization Of Water Environment Monitoring System In Poyang Lake Basin Based On

From the current actual situation,the Poyang Lake Basin water environment monitoring system mainly adopts the B/S structure model.The traditional B / S mode is to directly call the data in the model,in the browser to display.There are obstacles to heterogeneous models and data calls,and the solution to this barrier is to publish models and data into services.The traditional water quality inversion need to rely on professional software in advance inversion,inversion after the success of the results in the water environment monitor platform display.The solution to this problem is to directly describe the water quality inversion model.user completes the water quality reversal directly by call the service.SOA is business driven architecture,support the integration and sharing of Web services,enable interopera and reusability between services.Therefore,this paper is based on the Open Fund of Key Laboratory of National Geographic Survey and Geographic Information Bureau of Watershed Ecology and Geographical Environment: Design and Realization of Watershed Ecological and Geographic Environment Visualization Framework.And builds a complete information system for water environment monitoring of Poyang Lake Basin based on SOA.This is of great significance to the monitoring,analysis,interoperability and sharing of water environment in Poyang Lake Basin.The main work of this paper is:(1)Functional design and integration of service-oriented Poyang Lake Basin water environment monitoring systemTo solve the water environment monitoring process contains the data exists in the multisource isomorphism and other issues,to achieve the integration of spatial data and attribute data management,reducing the data resources and functional coupling.On this basis,the different functional design and development for the different size of the functional service module,to lift the function to achieve the relevance of the platform.At the same time,taking into account the inter calls between services and nesting,to explore the integration of Web services strategy.(2)SOA-based water quality inversion model Web service design and implementationIn the current water quality inversion calculation process,we need to rely on the professional software to carry on the parameter calculation,this research through the current commonly used water quality quantitative remote sensing monitoring method analysis and induction.The water quality inversion model based on SOA is designed to carry out the inversion of water quality information in Poyang Lake Basin.And the results of water quality inversion were obtained.(3)Implementation of Water Environment Monitoring System in Poyang Lake Basin Based onBased on SOA-based functional service and water quality inversion model service,the system is divided into functional modules such as measured data management,water quality monitoring and management,water monitoring and management and statistical reporting,map bookmarking,and 3D system.Call and nest the corresponding functional modules to design and implementation.And finally form a management information system that meets the requirements of water environment monitoring in Poyang Lake Basin.The system can adapt to and support the changing business needs quickly,conveniently and economically.
