基于FIRMSYS构架的MPU响应时间数学模型分析

Analysis of MPU Response Time Mathem atical Model based on FIRMSYS Framework

为了评价核电站DCS响应时间的测试方法中,重启MPU这个步骤是否必需,本文将响应通道涉及的物理部件进行耗时分析,并在此基础上建立对应的数学模型,通过大量的仿真,获得响应时间的统计概率分布,为测试中的试验步骤取舍提供了一定的理论支撑。

In this paper,we carry out the time consuming analysis of physical components involved in the test,and establish a corresponding mathematical model on this basis to evaluate whether it is necessary to restart MPU in the test method of DCS response time of nuclear power plant.Through a large number of simulation,the statistical probability distribution of response time is obtained,which provides a certain theoretical support for the selection of test steps during the test.
