Problems solved by technology

[0004] However, the nuclear power industry has very strict requirements for commodity-level items, and requires strict evaluation of their use effects. Currently, there is no unified standard evaluation method for the corresponding real-time operating system, and quantitative evaluation results cannot be given. In most cases, The effect is determined through trials, and it is possible to discover the problem that the real-time operating system is not applicable at the later stage of the project, which will cause huge losses to the project's research and development progress and cost

Abstract

The invention discloses a method and a device for evaluating a real-time operating system of a nuclear power instrument control system. The method specifically comprises the following steps of: determining a security level of a function executed by the instrument control system to which a to-be-evaluated real-time operating system is applied; determining an applicable standard of the to-be-evaluated real-time operating system according to the security level; function requirements and performance requirements of the real-time operating system to be evaluated are determined according to design requirements; determining a used evaluation model according to the application standard, the function requirement and the performance requirement; analyzing and calculating the to-be-evaluated real-time operating system to obtain an analysis result; and performing quantitative evaluation on the analysis result by using the evaluation model to obtain a quantitative evaluation result of the real-time operating system to be evaluated. The effect of the corresponding real-time operating system can be obtained without trial through evaluation, and whether the real-time operating system is applicable or not can be found as early as possible, so that loss of research and development progress and cost of the nuclear power instrument control system is avoided.

Description

technical field [0001] The present application relates to the field of nuclear power technology, and more particularly, to a method and device for evaluating a real-time operating system of a nuclear power instrumentation and control system. Background technique [0002] With the continuous development of computer technology, the use of digital instruments and control systems to replace traditional instruments has become the mainstream trend of new nuclear power plants. Most of the digital I&C systems are developed based on the corresponding real-time operating systems. The use of real-time operating systems to develop I&C systems has the advantages of short development cycle, strong scalability and high reliability. [0003] At present, the domestic nuclear power I&C system is mainly developed based on the commercial real-time operating systems provided by VxWorks and other domestic suppliers. These commercial real-time operating systems are all general-purpose products and...
