核电厂仪控系统中的实时操作系统应用研究

Research on Application of Real-Time Operating System in Instrument Control System of Nuclear Power Plant

实时操作系统(ROS)作为核电厂数字化仪表与控制系统中的核心组成部分具有不可替代的作用。由于其开发周期长、技术难度大,我国核电仪控实时操作系统严重依赖进口。随着国际形势的不断变化,“卡脖子”问题已对国家核电建设形成明显制约。综述了ROS的发展历史及特点,介绍了近年来ROS在我国核电厂仪控系统中的应用现状,分析了实时操作系统在核电工程应用中的主要问题,提出了核电仪控领域ROS的关键需求。该研究对我国未来自主化核电仪控ROS的研发有良好的促进作用。

Real-time operating system(ROS)plays an irreplaceable role as the core part of the digital instrument and control system in nuclear power plants.Because of its long development cycle and difficult technology,China’s nuclear and electric instrument control real-time operating system heavily depend on imports.With the constant change of the international situation,the problem of"jam neck"has formed obvious constraints on the national nuclear power construction.The development history and characteristics of ROS are reviewed,the application status of ROS in instrument control system of nuclear power plant in China in recent years is introduced,the main problems in application of ROS in nuclear power engineering are analyzed,and the key requirements of ROS in nuclear power instrument control field are put forward.The research is helpful for the future development of the autonomous ROS for nuclear electric instrument control in China.
