摘要:
为深入认识燃气管网泄漏事故的发生发展机理，提高事故分析预测的自动化、智能化、数字化水平，利用知识图谱对燃气管网泄漏事故进行研究。在事故案例分析的基础上，从人-物-环-管的角度对燃气泄漏过程以及火灾爆炸次生事故的相关实体进行归纳梳理，对实体间的逻辑关系和非逻辑关系进行辨识，并对实体的属性进行分类，进而构建出较为全面的燃气管网泄漏事故知识图谱。在此基础上，搭建BP神经网络模型，基于已知实体或属性状态，预测相关联其他实体或属性的状态。研究结果表明：燃气管网知识图谱能够有效展示燃气管网泄漏事故发展的动态过程及相关要素，结合BP神经网络能够有效预测事故的发展路径及相关状态，从而提高燃气管网泄漏事故的分析预测水平与效率。
Abstract:
In order to fully understand the occurrence and development mechanism of the leakage accident of gas network,and improve the automation,intelligence and digitalization level of accident analysis and prediction,the leakage accident of gas pipeline network were studied by using the knowledge graph.On the basis of accident cases analysis,the related entities of gas leakage process and secondary accidents of fire and explosion were summarized from the perspective of man-material-environment-management.The logical and non-logical relationship between the entities were identified,and then the attributes of entities were classified to construct a more comprehensive knowledge graph of gas pipeline network leakage accidents.Based on this,a BP neural network model was constructed to predict the state of related other entities or attributes based on the known entity or attribute state.The results showed that the knowledge graph of gas pipeline network could effectively demonstrate the dynamic process and relevant elements of the development of gas pipeline network leakage accidents,and the combination of BP neural network could effectively predict the development path and relevant states of the accidents,thus improving the analysis and prediction level and efficiency of gas pipeline network leakage accidents.
