核电仪控实时操作系统软件需求研究

Requirements Research on Nuclear Power Instrumentation and Control Real-Time Operating System Software

实时操作系统作为核电厂数字化仪控系统的核心组成部分,在核电厂数字仪控系统中发挥重要作用。但我国核电厂应用的实时操作系统严重依赖进口。为打破国外技术壁垒、实现核电厂的实时操作系统完全自主化,对适用于核电厂的实时操作系统软件需求进行研究。深入学习了实时操作系统的经典书籍,研究了核电软件法规和实时操作系统相关标准,调查了实时操作系统在核电数字仪控系统中的应用需求,分析了在核电厂成熟应用的友商产品的软件需求。提出了适用于核电厂数字仪控系统的可靠性和安全性的实时操作系统软件需求,包含外部接口需求、功能需求、性能需求和软件系统属性等。该研究为后续实现独立自主的核电仪控实时操作系统软件的设计及研制奠定了基础。

As the core component of nuclear power plant digital instrumentation and control system,real-time operating system plays an important role in nuclear power plant digital instrumentation and control system.However,China’s nuclear power plants rely heavily on imported real-time operating systems.To break the foreign technical barriers and realize the complete autonomy of the real-time operating system of nuclear power plants,the real-time operating system software requirements applicable to nuclear power plants are studied.The classic books on real-time operating system is studied deeply,the nuclear power software regulations and real-time operating system related standards are researched,the application requirements of real-time operating system in nuclear power digital instrumentation and control system are investigated,and the software requirements of the mature application of friendly products in nuclear power plants are analyzed.The software requirements of real-time operating system for nuclear power plant digital instrumentation and control system in terms of reliability and safety are proposed,including external interface requirements,functional requirements,performance requirements and software system attributes,etc.This study lays a foundation for the design and development of sequential independent real-time operating system software for nuclear power instrumentation and control.
