【摘要】：從當前的實際情況來說鄱陽湖流域水環(huán)境監(jiān)測系統(tǒng)主要采用B/S結構模型。傳統(tǒng)的B/S架構是通過調用模型里的數(shù)據(jù),在網頁中進行展示。對于異構模型和數(shù)據(jù)調用則存在障礙,解決這種障礙的措施是將模型和數(shù)據(jù)都發(fā)布成服務。傳統(tǒng)的水質反演都需要依靠專業(yè)的軟件提前進行反演,反演成功后把反演結果在水環(huán)境監(jiān)測平臺展示。面對這一問題的解決方法是構建水質反演模型服務。用戶通過調用服務直接完成水質反演。SOA是以業(yè)務為核心的架構模式,支持對Web服務的整合與共享,使服務之間實現(xiàn)相互關聯(lián)與可重用。本論文構建了基于SOA架構下鄱陽湖流域水環(huán)境監(jiān)測綜合信息系統(tǒng)。此舉對鄱陽湖流域水環(huán)境監(jiān)測、分析、互操作與共享問題具有至關重要的意義。本文所做的主要工作有:(1)面向服務的鄱陽湖流域水環(huán)境監(jiān)測系統(tǒng)的功能設計與整合解決水環(huán)境監(jiān)測過程中包含的數(shù)據(jù)存在的多源異構等問題,實現(xiàn)了空間數(shù)據(jù)和屬性數(shù)據(jù)的一體化管理,降低了數(shù)據(jù)資源與功能的耦合度。在此基礎上,將不同的功能設計開發(fā)為不同粒度的功能服務模塊,解除功能實現(xiàn)與平臺的相關性。同時,考慮到服務之間的相互調用和嵌套,探索了Web服務的整合策略。(2)基于SOA的水質反演模型Web服務的設計與實現(xiàn)當前水質反演計算過程中都需依靠專業(yè)的軟件進行參數(shù)的計算,本研究通過對當前常用的水質定量遙感監(jiān)測方法的分析與歸納。設計了基于SOA下的水質反演模型,進行鄱陽湖流域水質信息的反演。得到了滿足監(jiān)測要求的水質反演結果。(3)基于SOA的鄱陽湖流域水環(huán)境監(jiān)測系統(tǒng)實現(xiàn)以基于SOA構建的功能服務和水質反演模型服務為基礎,將系統(tǒng)劃分為實測數(shù)據(jù)管理、水質監(jiān)測管理、水量監(jiān)測管理和統(tǒng)計報表、地圖書簽、三維系統(tǒng)等功能模塊,通過對服務間的相互調用和嵌套對相應功能模塊進行設計與實現(xiàn)。最終形成滿足鄱陽湖流域水環(huán)境監(jiān)測要求的管理信息系統(tǒng),該系統(tǒng)能夠快速、經濟地適應并支持不斷變化的業(yè)務需求。
[Abstract]:At present, the water environment monitoring system of Poyang Lake Basin is mainly based on B _ S structure model. The traditional BES architecture is displayed in the web page by calling the data in the model. There are obstacles to heterogeneous models and data calls, and the solution to this obstacle is to publish models and data as services. The traditional inversion of water quality needs to be carried out in advance by professional software. After the inversion is successful, the inversion results will be displayed on the monitoring platform of water environment. The solution to this problem is to construct water quality inversion model service. Web is a business-centered architecture pattern, which supports the integration and sharing of SOA services, so that the services can be interrelated and reused. In this paper, the integrated information system of water environment monitoring in Poyang Lake Basin is constructed 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 as follows: (1) the functional design and integration of service-oriented water environment monitoring system in Poyang Lake Basin to solve the problems of multi-source heterogeneous data contained in the process of water environment monitoring, and so on. The integrated management of spatial data and attribute data is realized, and the coupling degree of data resources and functions is reduced. On this basis, different functional design is developed as a function service module with different granularity, and the correlation between the function realization and the platform is removed. At the same time, considering the mutual invocation and nesting of services, The integration strategy of Web services is explored. (2) the design and implementation of SOA-based water quality inversion model Web services need to rely on professional software to calculate the parameters in the current process of water quality inversion calculation. In this study, the commonly used quantitative remote sensing monitoring methods of water quality are analyzed and summarized. A water quality inversion model based on SOA is designed to retrieve water quality information in Poyang Lake Basin. The results of water quality inversion are obtained. (3) the water environment monitoring system of Poyang Lake Basin based on SOA is divided into measured data management based on the functional service based on SOA and the service of water quality inversion model. The function modules, such as water quality monitoring management, water quantity monitoring management and statistical report, map bookmark, three-dimensional system, are designed and realized by calling and nesting each other among services. Finally, a management information system is formed to meet the requirements of water environment monitoring in Poyang Lake Basin. The system can adapt to and support the changing business needs rapidly and economically.
