摘  要:动态重构是一种在控制系统运行时进行控制组态无扰更新的技术,它与控制系统的体系结构、控制组态方法以及管理机制等技术问题密切相关。本工作研究动态重构技术的基本特征,探讨控制组态技术标准与动态重构之间的内在联系。基于图形化的控制组态方法,提出一种独立于控制站计算平台的数据引擎模型和相应的工程实现技术,将动态重构过程转化为控制站实时数据库的数据更新过程。采用多代理软件工程的方法实现数据引擎机制。提出在可编程控制器(PLC)中实现动态重构技术的方法,并将该技术应用到发电机组的分布式控制系统中。对动态重构技术在核电站I&C系统中应用的有关问题也进行了探讨。Dynamic reconfiguration is a technology by which control configuration can be updated without disturbance when the control system is in operation and is closely related to the architecture, control configuration and management mechanism of the control system. The characteristics of dynamic reconfiguration were studied and the intrinsic relationship between dynamic reconfiguration and control configuration standard was analyzed. Based on graphic configuration, the data engine model and its implementation independent of any control platform were presented, implying that the dynamic reconfiguration was converted to data-updating in the real data base of control station. Data engine was programmed by the multiagent system software. The method of dynamic reconfiguration in the programmable logic controller (PLC) and its application to the distributed control system in power generating units were described.The application of dynamic reconfiguration in NPP I&C system was also discussed.
