The architecture design and technical implementation of the configuration software,Huaneng Rivival Distributed Control System(DCS)(HNICS-316),is introduced,which is the new generation product of domestic industrial control system and has the characteristics of configuration design and debugging.This software is developed on domestic workstation with a layered component architecture based on the process of configuration design.At the same time,a novel modular integration method based on a data-driven scheme and message bus technology is proposed.On this basis,a component-based data management system and a graphical system with model/view structure are contrived to realize the fast refreshment of data from memory to the human machine interface.The above design pattern reduces the coupling between modules and the complexity of the software,improves the maintainability,scalability and portability of the software,hence simplifies the procedure of crossplatform development of the software and enhances the efficiency of parallel development.In order to solve the insufficient software and hardware performance of the domestic workstation,and achieve a lightweight deployment of the software,new proposals of configuration data management system based on controller device lock mechanism,segmented file structure with high granularity and low resource consumption,and master/salve device data synchronization technique based on multi-level configure analysis method are offered.The configuration resource share mechanism based on dynamic-grading tag name checking is designed to resolve the data define confliction problem when multiple users editing on the workstation at the same time,which improves the efficiency of configuration downloading and master/slave data synchronization under fast control cycle.At the same time,it reduces the software and hardware resource consumption of the workstation and simplifies the deployment procedure of the software,realized the stable and efficient operation of the software on domestic workstation.The software has been successfully applied in 300 MW and 1000 MW thermal power units.By field application and the testing of third-party authority,the software is stable,convenient,and flexible enough,which meets the application requirements of large thermal power units.
