试验数据采集系统的信号实时性分析

The Design Analysis of Test Data Acquisition System

试验数据采集系统是专用仪控系统之一,主要在核电厂调试、运行和维修中,为其他系统提供监视、记录和分析手段以及相关的瞬态和故障录波功能。本文从试验数据采集系统的功能要求出发,结合不同平台试验数据采集系统设计,分析了目前核电设计中典型的实施方案,以及各实施方案在信号实时性方面的优缺点,为后续电站该系统的设计提供了指导作用。

Test data acquisition system(KDO)is one of the special instrument control systems,it is mainly used in the commerssioning,operation and maintenance of the nuclear power plant to provide monitoring,recording and analysis methods and related transient and perturbography function.This paper is based on the requirements of KDO system,combines with different plantforms,analysis the current typical implementation plan,including advantages and disadvantages in real time signal.Also,it provides a guidance for the future design of the system in other nuclear power plant.
