基于本体的核电运行规程模型构建方法

运行规程是核电厂安全运行必须遵守的操作程序。核电厂运行规程繁多、查找不便,现行电子规程存在精简程度不够、内容关联程度弱、相比纸质规程优越性不强等问题。为核电厂设计一种基于本体模型的简洁高效电子化规程系统势在必行。以某核电厂化学和容积控制系统运行规程为例,运用本体模型理论,分析规程文本、挖掘规程知识、提取关键概念。使用本体开发工具构建系统,实现了电子规程及其可视化,可浏览电子规程和知识库,查询关键操作。此构建方法同样适用于其他系统的运行规程,不仅使本体知识实现重用和共享,而且有利于查询、理解、记忆规程,能够为核电厂操纵员使用规程提供帮助,提高效率,增强核电厂的安全性和智能化。

Model Building Approach for Nuclear Power Operation Procedure Based on Ontology

Nuclear power operating procedures are the operational procedures that must be followed for the safe operation of nuclear power plants. Having a lot of texts, the operation procedures are inconvenient for users to browse. However, the current electronic procedures have problems such as lack of simplification, weak content relevance, and less superiority than paper procedures. It is imperative to design a simple and efficient electronic procedure system based Ontology model for nuclear power operation. This paper takes the operating procedures of the chemical and volume systems in a nuclear power plant as an example, uses the ontology model theory, analyzes the text of procedures, develops the knowledge of the procedures and extracts key concepts. Using the ontology development tool to build the system, the electronic procedures and visualization are realized. This construction method is also applicable to the operating procedures of other systems, which not only enables the reuse and sharing of ontology knowledge, but also facilitates querying, understanding, and memorizing procedures. It can help the operators in nuclear power plants to use procedures, thereby improving the efficiency and enhancing the safety and intelligence of nuclear power plants.
