数字化堆外核测量系统设计与实现

Design and Implementation for Digital Outer Reactor Nuclear Measurement System

为满足核电厂堆外核测量系统的数字化改造需求,设计了一种基于Lab VIEW平台的堆外核测量系统,并解决了该系统传统上位机显示功能单一、无数据记录和存储功能、无运行性能监测功能、无用户管理功能等问题。充分运用该平台的内存优化、面向对象编程、高级控件应用、报表工具包等技术,建立了一套集就地音频控制、数据采集和处理于一体的上位机系统,并使之满足数字化系统的要求。该系统在运行性能监测、故障自诊断等方面作了创新性研究,在监测范围、数据可靠性和显示等方面作了重大提升。综合运用计算机和数据库等多学科技术,详细阐述了程序架构的设计、人机交互界面的设计、通信网络搭建、子界面的动态调用等实现方法。阳江核电厂3号机组的堆上试验结果表明,该系统具有配置方便、易扩展、运行稳定、数据处理能力强等优点。

To meet the demands for digitized retrofit of the outer reactor nuclear measurement system,a system for outer reactor nuclear measurement based on LabVIEW platform is designed to solve the problems of traditional host computer, e. g. , unitary display function, lack of data record and storage capabilities, running performance monitoring function and user management functions, etc. Making full use of the technologies of memory optimization, object - oriented programming, application of advanced controls and reporting toolkit, etc. , the host computer integrating the local audio control, data acquisition and processing is established, thus the demands for digitized system are satisfied. For this system, the innovative research on monitoring system performance and fault self - diagnosis is carried out, and significant upgrade on the scope of monitoring, data reliability and data display methods is made. By comprehensively using multidisciplinary technology of computer and database, the design of the human - computer interaction, the construction of communication network, and the implementing method of dynamic calling of sub - panels are expounded in detail. Through the tests for unit 3 of Yang Jiang nuclear power station,the result shows that this system has the advantages of convenient configuration, ease extension, good running stability and strong data processing capability, etc.
