摘要
随着核电仪控技术水平的提高,全数字化仪控技术在核电系统中得到了广泛地应用和推广。核电DCS控制系统由传统的模拟技术正朝着全数字化技术急速推进。在我国在建核电站中,全部采用了数字化控制系统技术,但大都为国外产品。为了实现国产化的要求,多家单位都针对核电站数字化控制系统展开了研究。本文主要针对常规的数字化控制系统中的数据库所采用的数据压缩方法进行论述。
With the improvement of technical level of Nuclear Power Instrumentation ＆ Control, digital control technology has been widely used and promoted in the Nuclear power system, nuclear DCS system rapidly change from traditional analog technology to fully digital technology. Nuclear power plants under construction in China all adopt the technology of digital control system, but most are foreign products. In order to achieve the requirements of localization, many units have carried out the research on nuclear digital control system.In this paper, the digital control system in a conventional database data compression method.
