核电站风险监测系统数据库的设计和实现

Design and implementation of a database for nuclear power plant risk monitor

风险监测系统是一种能辅助和优化核电站运行和维修决策的实时风险在线分析工具。数据库作为风险监测系统的重要部分,是分析计算工作的基础,而且其涉及数据量大、数据关系复杂、使用对象广泛,因此其设计和实现是风险监测系统的关键环节之一。本文采用了面向对象关系设计模式进行了数据库设计,并介绍了在数据库实现中面临的一系列问题和为解决这些问题所引入的方法和技术。实践表明数据库设计满足系统要求,安全性和性能满足用户要求。

Risk monitor is a plant specific real-time analysis tool used to assist and optimize the plant＇s operation and decision-making of maintenance.As an important part of risk monitor,database is the basis of computing and analyzing and is used widely,which involves volumes of data and complicated relation among data.So database is a key question in risk monitor＇s implementation.In this paper object-oriented relationship database was adopted,and in the process of implementation many methods and technology were imported to solve some problems in the implementation of database.The practice demonstrated that the design of the database and the database＇s security and performance could meet the need of risk monitor.
