基于IA_DCS系统外接冗余回填型历史库的安装与调试

Installation and Debugging of an IA_DCS-based External Redundant Backfilling Historical Database

以某核电厂3、4号机组DCS数字化系统历史库为研究对象,介绍了基于福克斯波罗IA_DCS系统外接的冗余回填型历史库。阐述了此类型历史库的配置要求、网络结构等,介绍了故障情况下完整安装与调试过程,并总结该过程中的步骤细节与注意事项,为维护工程师提供了一种极端情况下的处理措施,对于其他使用Wonderware产品的历史库有一定借鉴意义。

This essay takes the DCS digital system history database of Units 3 and 4 of a certain nuclear power plant as the research object,mainly outlining a redundant backfill type history database based on the external connection of the Foxboro IA_DCS system.It mainly clarifies the configuration requirements,network structure,and other aspects of this type of historical library,with focuses on the complete installation and debugging process in case of failure,and summarizes the steps and precautions in this process.It provides an extreme handling measure for maintenance engineers,and potentially helpful inspiration for other historical libraries using Wonderware products.
