基于IA系统的冗余和高速历史库的搭建和维护

Building and maintaining the redundant historian and high-speed historian based on IA

主要介绍数字化系统中涉及数据存储读取相关的历史库的整体硬件软件配置、供电和网络的搭建、正常运行期间的维护和注意事项,理清高速历史库和冗余历史库的关联和差异,以期能更清晰地使用和维护历史库。历史库通过硬件获取机组数据并存储,可通过软件处理,根据需要提供图形、曲线和报表等,将数据直观地提供给使用者。核电站的数据非常重要,它不仅仅具有日常机组运行的监视功能,还有对机组设备维修时缺陷分析的指导作用,保证机组更加稳定地运行,作为维护者需要了解整体的软硬件架构,保证历史库的正常运行。

This paper mainly introduces configuration of hardware and software,power supplying and network building,maintaining and some matters needing attention during normal operation of the historian in digital system relates to data storing and reading,and gets clear on the difference and relationship between the high-speed historian and redundant historian,in order to more clearly use and maintain the historian.The historian accesses and stores unit data by hardware,and the data can be transformed into a graph,trend and report according to the needs,directly available to the user.The nuclear power unit data is very important,because it not only has the function of monitoring the daily operation of the unit,but also has the guiding effect on defect analysis when the unit equipment repairing,assuring more stable operation.The defenders need to understand the hardware and software architecture,to ensure the normal operation of the historian.
