发电企业实时数据库管理系统的研究与实现
|
摘要
实时数据库管理系统是指对数据存储、传输、读取有严格的时间限制的数据库管理系统,与关系型数据库管理系统的区别在于实时数据库管理系统的正确性不但依赖于逻辑结果,而且还依赖于逻辑处理的时间。近年来随着电力企业对信息化需求的提高,实时数据库管理系统已经成为电力企业自动化系统中必不可缺少的重要部分。
实时数据库管理系统在发电企业中的主要应用是对生产控制系统产生的数据进行实时的优化、压缩和保存。实时数据作为企业的重要数据资源为企业决策提供支持,并对提高企业管理水平和生产效率、保证发电安全稳定运行、增强企业的竞争能力以及提高企业的综合效益具有重要意义。
Real Time Database Management System (RTDMS) is a kind of database management system which had strict constraints on delay of the data storage, transmitting, and reading. The different difference between of RTDMS and relation database management system (RDMS) is that the validity of RTDMS reliability was not only depending on the logic results but also depend on the delay of the logic processing. Recently, because of the high requirements on the information technology of the electric power enterprises, RTDMS has become one of the most important parts of the power enterprise automation system.The most important application of RTDMS in electric power enterprises is that it can do the real time optimization, compression and reservation on the data which are produced by the PCS(Product Control System) or DCS(Distributed Control System). Being the most important data resource, real time data not only provide the enterprises decision supports, but also on many other aspects, such as management enhancements, production efficiency, security and stabilization on electricity generating, competition ability, and the integration benefits.Zhou Chao (Applied Computer Technology) Directed by Prof. Wu Kehe
