摘　　要：针对当今电厂众多应用系统中存在的数据冗余和数据不一致问题,提出一种基于"虚拟数据层"的数据交互管理平台。通过对数据库和"虚拟数据层"之间的映射进行建模,建立了数据库和虚拟数据层之间的映射函数,通过以"虚拟数据层"为中心的数据交互管理平台,实现了应用系统间数据统一和互用。平台结合Web Service技术,实现了对实时数据库的跨平台访问,减少电厂各应用系统数据维护复杂度,提高数据利用率,实现厂级各应用资源整合,应用前景广泛。Aiming to solve the problems of data redundancy and data inconsistency in power plant application systems, this paper introduced a data interaction management platform based on ＂virtual data layer＂. By modeling the map between database and virtual data layer, a mapping function between database and virtual data layer was established. By this data interaction management platform centered on ＂virtual data layer＂, intersystem data unification and interoperate were implemented. Combined with Web Service Technology, this platform provides a cross-platform access to the real-time database, reduces the complexity of power plant application systems data maintenance, increases data utilization, and implements the integration of plant-level application resource. It has a great application prospect.
