摘要
数据存档系统是控制棒驱动机构(Control Rod Drive Mechanism,CRDM)样机控制系统的重要组成部分,主要用于存储控制棒的实时、报警信息及其他设备信息等数据,一方面能够使运行人员对熔盐堆CRDM样机的运行、调试和维修等工况进行分析和处理,另一方面为今后基于数据分析的预警和诊断技术发展积累数据资源。本文基于开源、数据类型和接口丰富、扩展功能强大的关系型数据库Postgre SQL,设计实现了熔盐堆CRDM样机数据存档系统的数据库。为提高数据库的性能并确保安全可靠的存储数据,在数据采集上采用了双机热备技术,同时使用Java语言开发了控制棒棒位检索工具并连接数据存档系统。该系统在熔盐堆CRDM样机中的成功应用证明其是一种先进的、低成本的、稳定的数据存档系统。
[Background] Data archiver is an important part of the molten salt reactor control rod drive mechanism （CRDM） prototype control system. It is used to store real-time parameters, alarm and other information of equipment, etc., and accumulate data for further data-based prognostics and diagnostics. [Purpose] This study aims to develop a CRDM data archiver based on PostgreSQL. [Methods] A dual-machine hot standby technique was employed to improve the performance of database and store data reliably. The control rod position retrieval tool was implemented by using Java programming. [Results] A data archiver based on PostgreSQL was developed and applied to CRDM prototype. [Conclusion] The data archiver designed based on PostgreSQL is proved to be an advanced, low cost and stable system.
