数据汇聚与发布服务在水环境实时监控系统中的应用

以“苏州市古城区水环境实时监控系统”为背景，基于智能Agent和Web服务的思想，提出了一类数据汇聚与发布服务的模型并予以实现。数据汇聚子模块收集来自不同单位、不同地点、不同监测仪及采用不同测试方法所得到的数据，主要解决数据格式不一致及同一监测项多数据源的融合等问题；数据发布子模块为不同权限的用户提供不同程度、不同形式的数据共享。所实现的数据汇聚与发布服务具有良好的可扩展性和互操作性，适用于大规模的水环境分布式应用。

APPLICATION OF DATA INTEGRATION AND RELEASE SERVICE IN WATER ENVIRONMENT REAL-TIME SUPERVISORY CONTROL SYSTEM

Based on intelligent Agent and Web services, this paper presents a model of the data integration and release service, which is implemented and applied in the water environment real-time supervisory control system in the old city zone of Suzhou, Jiangsu. The sub-module of data integration collects the data incoming from different departments ,sites, monitors or distinct testing methods, and it also solves the problems of Data Format Disagreement and Multi-sources Data Fusion. The sub-module of data release provides data for users with dissimilar privileges in different ways. The Web Service is extensible and mutually operational, which is suitable for water environment distributing application in large scale.
