【摘要】：我國(guó)水資源緊缺,時(shí)空分布不均衡,生態(tài)系統(tǒng)脆弱,水質(zhì)污染嚴(yán)重。南水北調(diào)中線工程是解決北方地區(qū)資源型缺水問(wèn)題的特大型跨流域調(diào)水工程。為全面監(jiān)控工程輸水水質(zhì),加強(qiáng)水質(zhì)管理,充分發(fā)揮工程效益,需要在工程輸水干線上建立水質(zhì)監(jiān)測(cè)系統(tǒng),開(kāi)展水質(zhì)監(jiān)測(cè)和預(yù)測(cè)預(yù)報(bào)工作,及時(shí)、準(zhǔn)確掌握輸水干線的水質(zhì)變化情況,有效處理突發(fā)性水污染事件,保護(hù)輸水干渠水質(zhì),確保沿線供水安全。本文在總結(jié)國(guó)內(nèi)外水質(zhì)監(jiān)測(cè)研究現(xiàn)狀的基礎(chǔ)上,分析了南水北調(diào)中線工程水質(zhì)監(jiān)測(cè)系統(tǒng)的功能需求,建立了基于J2EE技術(shù)體系,采用C/S和B/S混合方式的水質(zhì)監(jiān)測(cè)系統(tǒng)框架。 水質(zhì)監(jiān)測(cè)應(yīng)用系統(tǒng)設(shè)計(jì)思路是：采用技術(shù)成熟、符合業(yè)界主流發(fā)展方向的架構(gòu),設(shè)計(jì)要考慮技術(shù)成熟與先進(jìn)的平衡、易用性與系統(tǒng)魯棒性的平衡、長(zhǎng)期運(yùn)維成本與一次性建設(shè)成本的平衡、規(guī)范開(kāi)放與安全穩(wěn)定的平衡�；谙冗M(jìn)性和開(kāi)放性原則,系統(tǒng)采用J2EE技術(shù)體系；采用C/S和B/S混合方式實(shí)現(xiàn)不同的功能需求；采用成熟的Oracle數(shù)據(jù)庫(kù)系統(tǒng)和ArcGIS系統(tǒng)等主流技術(shù)和產(chǎn)品,以保證系統(tǒng)的穩(wěn)定性,并具有很好的可移植性、可擴(kuò)展性；能夠采用多層組件技術(shù),跨平臺(tái)使用；使所有的應(yīng)用軟件都是配置實(shí)現(xiàn)的,當(dāng)用戶業(yè)務(wù)發(fā)生變化時(shí),不需要重新編碼,只需要修改相應(yīng)配置即可實(shí)現(xiàn)。 水質(zhì)監(jiān)測(cè)系統(tǒng)包括水質(zhì)信息采集系統(tǒng)和水質(zhì)監(jiān)測(cè)應(yīng)用系統(tǒng)。水質(zhì)監(jiān)測(cè)系統(tǒng)采用三層體系結(jié)構(gòu),分別由基礎(chǔ)設(shè)施、應(yīng)用支持平臺(tái)、應(yīng)用層三層構(gòu)成。其主要業(yè)務(wù)內(nèi)容包括水質(zhì)信息采集與應(yīng)用兩大部分,其中水質(zhì)信息采集業(yè)務(wù)包括監(jiān)測(cè)站網(wǎng)設(shè)置、水質(zhì)固定監(jiān)測(cè)、水質(zhì)自動(dòng)監(jiān)測(cè)、水質(zhì)動(dòng)態(tài)監(jiān)測(cè)等,本文確定了水質(zhì)監(jiān)測(cè)站網(wǎng)的布設(shè)方案、水質(zhì)采樣方案、監(jiān)測(cè)參數(shù)及分析方法。水質(zhì)監(jiān)測(cè)應(yīng)用系統(tǒng)由監(jiān)測(cè)數(shù)據(jù)管理、站網(wǎng)管理系統(tǒng)、評(píng)價(jià)系統(tǒng)、整編匯系統(tǒng)、預(yù)測(cè)預(yù)報(bào)系統(tǒng)、信息查詢系統(tǒng)、會(huì)商支持、信息發(fā)布系統(tǒng)等8個(gè)子系統(tǒng)組成,本文詳細(xì)描述了各子系統(tǒng)的層次結(jié)構(gòu)及具體功能。 最后,對(duì)全文內(nèi)容進(jìn)行總結(jié),并對(duì)有待進(jìn)一步研究的問(wèn)題進(jìn)行展望。
[Abstract]:China is short of water resources, uneven distribution of time and space, fragile ecosystem and serious water pollution. The South-to-North Water transfer Project is a super large water transfer project for solving the problem of water shortage in North China. In order to comprehensively monitor the water quality of the project, strengthen the water quality management and give full play to the project benefit, it is necessary to establish a water quality monitoring system on the main water conveyance line of the project, to carry out the water quality monitoring and forecasting work in a timely manner. The change of water quality in the main water conveyance is accurately understood, the sudden water pollution events are effectively dealt with, the water quality of the main canal is protected, and the safety of water supply along the route is ensured. On the basis of summarizing the present situation of water quality monitoring at home and abroad, this paper analyzes the functional requirements of the water quality monitoring system of the South-to-North Water transfer Project, and establishes a technical system based on J2EE. The framework of water quality monitoring system using C / S and B / S mixed mode. The design idea of water quality monitoring application system is to adopt a framework that is technically mature and in line with the mainstream development direction of the industry. The design should consider the balance between technology maturity and advanced technology, and the balance between usability and system robustness. The balance between long-term operation cost and one-time construction cost, standard opening and safety and stability. Based on the principle of advanced nature and openness, the system adopts J2EE technology system, uses the mixed mode of C / S and B / S to realize different functional requirements. Adopt mature Oracle database system and ArcGIS system and other mainstream technologies and products to ensure the stability of the system, and have good portability, scalability, multi-tier component technology, cross-platform use; All the applications are configured and implemented. When the user's business changes, there is no need to re-encode, only need to modify the corresponding configuration can be implemented. Water quality monitoring system includes water quality information collection system and water quality monitoring application system. The water quality monitoring system is composed of three layers: infrastructure, application support platform and application layer. Its main business content includes two parts: water quality information collection and application. Among them, water quality information collection business includes monitoring station network setting, water quality fixed monitoring, water quality automatic monitoring, water quality dynamic monitoring, etc. In this paper, the layout scheme, water quality sampling scheme, monitoring parameters and analysis method of water quality monitoring station network are determined. The water quality monitoring application system consists of eight subsystems, such as monitoring data management, station network management system, evaluation system, integration system, forecasting system, information query system, meeting support, information publishing system, etc. This paper describes the hierarchical structure and specific functions of each subsystem in detail. Finally, the content of the full text is summarized, and the problems to be further studied are prospected.
