摘要
安全级图形显示单元作为安全级核电控制系统的配套人机交互界面,用于为核电厂操作员提供安全级核电控制系统内的状态监视和手动控制功能。随着国内核电产业的发展,核电业主对安全级图形显示单元提出更高的应用要求,而现有的安全级软件设计原则限制了安全级图形显示单元功能的持续改进。本文通过对安全级图形显示单元的系统功能和底层支撑技术的分析,提出通过多协处理器并行化方法改进安全级图形显示单元的总体设计,并详细阐述了该方法的系统架构、运行机制、技术实现及其优劣性。
As the human interface of safety Digital Control System(DCS),the Safety Video Display Unit(SVDU)is used to provide nuclear power plant operators with the functions of status monitor and manual operation.With the development of domestic nuclear power industry,owners of the nuclear power plant put forward higher requirements for SVDU.However,the existing safety-level software design principles have limited the continuous improvement of SVDU.This paper analyzed the system functions and underlying supporting technologies of SVDU,then put forward a method based on parallelization of multi-processor to improve the overall design for SVDU.At last,this paper described the system structures,running mechanisms and technical realizations of this method as well as its superiority and inferiority.
