【摘要】：我国水资源紧缺,时空分布不均衡,生态系统脆弱,水质污染严重。南水北调中线工程是解决北方地区资源型缺水问题的特大型跨流域调水工程。为全面监控工程输水水质,加强水质管理,充分发挥工程效益,需要在工程输水干线上建立水质监测系统,开展水质监测和预测预报工作,及时、准确掌握输水干线的水质变化情况,有效处理突发性水污染事件,保护输水干渠水质,确保沿线供水安全。本文在总结国内外水质监测研究现状的基础上,分析了南水北调中线工程水质监测系统的功能需求,建立了基于J2EE技术体系,采用C/S和B/S混合方式的水质监测系统框架。水质监测应用系统设计思路是：采用技术成熟、符合业界主流发展方向的架构,设计要考虑技术成熟与先进的平衡、易用性与系统鲁棒性的平衡、长期运维成本与一次性建设成本的平衡、规范开放与安全稳定的平衡。基于先进性和开放性原则,系统采用J2EE技术体系；采用C/S和B/S混合方式实现不同的功能需求；采用成熟的Oracle数据库系统和ArcGIS系统等主流技术和产品,以保证系统的稳定性,并具有很好的可移植性、可扩展性；能够采用多层组件技术,跨平台使用；使所有的应用软件都是配置实现的,当用户业务发生变化时,不需要重新编码,只需要修改相应配置即可实现。水质监测系统包括水质信息采集系统和水质监测应用系统。水质监测系统采用三层体系结构,分别由基础设施、应用支持平台、应用层三层构成。其主要业务内容包括水质信息采集与应用两大部分,其中水质信息采集业务包括监测站网设置、水质固定监测、水质自动监测、水质动态监测等,本文确定了水质监测站网的布设方案、水质采样方案、监测参数及分析方法。水质监测应用系统由监测数据管理、站网管理系统、评价系统、整编汇系统、预测预报系统、信息查询系统、会商支持、信息发布系统等8个子系统组成,本文详细描述了各子系统的层次结构及具体功能。最后,对全文内容进行总结,并对有待进一步研究的问题进行展望。
[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.
