水电厂生产管理系统中XML模型驱动架构的应用

Application of XML Model-Driven Architecture in the Production Management System of Hydropower Plant

针对以往发电集团水力发电企业在信息化过程中存在的功能重复开发实施、开发成本居高不下、后期系统维护代价较高的情况,文章提出了一种基于可扩展标记语言(e Xtensible Markup Language,XML)描述的轻量化模型驱动架构技术的快速开发实施方法。以中国华电集团公司福建分公司下属的多家水力发电企业的生产管理系统建设为例,分析了基于XML描述的业务模型的分析提取、业务模型的定义以及直接基于模型的解析运行机制。通过比较基于模型驱动技术构建的系统与其他系统发现,文章提出的方法在加快水电厂生产管理系统的开发实施以及提高系统对需求变更的快速响应上具有较好的适用性,相关技术在类似领域的信息系统建设中具有较好的应用前景。

Aiming at the problems such as repeated function, the higher development and maintenance cost in Hydropower plant information development, this paper puts forward a rapid development and implementation method based on the lightweight model driven architecture techniques described by the Extensible Markup Language（XML）. Taking several production management systems in hydropower enterprises of China Huadian Corporation Fujian Branch as examples, this paper analyzed the extraction, the definition and the analysis operation mechanism of the business models based on XML. Through comparing the differences between the system based on model driven techniques and other systems, a result is obtained that the proposed method has better applicability in accelerating the development and implementation of hydropower plant production management system and improving the system’s quick response ability. Related techniques would have a good prospect in the similar information system construction process.
