摘要
电厂的远动数据库有数据量大、更新频率快、准实时的特点。提出了一种在物理隔离环境下内外网远动数据库的数据同步方案。该方案模块划分清晰、通用性好、易于实现,并且不影响内网源数据库和其上的应用系统的正常运行。然后针对SQL Server 2000给出了同步系统实现,经实际运行检验,该方案可行,达到了设计目标。
Tele - control database of power plant is characteristic of enormous data, fast update frequency and quasi real- time. Proposed a tele- control data synchronization scheme based on GAP device. The scheme＇s modular division is clearly, easy to be realized, and intranet source database and application system can run normally. Particularly, implemented the synchronization system for SQL Server2000, which is proved to be highly effective,stable and reliable in real missions.
