摘要
为解决缆机运行管理过程中,大量多源异构结构化和非结构化知识难以复用及知识管理效率低的问题,分析缆机安装和运维过程中积累的大量技术规范、专家经验等安全知识,提取缆机运行相关实体类,采用五元组模型结构化表达缆机安全运行本体知识,并建立类间二元关系,使用Protégé中的本体表达语言程序化表示;构建缆机实体、安全预警、应急预案3大领域本体知识库;采用3Dmax软件,构建缆机运行三维场景模型,导入Unity3D引擎,在用户界面和交互功能中,实现本体知识库知识检索;针对缆机各实体存在的安全隐患、事故实例、应急预案,构建完整的缆机安全运行知识检索三维可视化平台.结果表明:缆机安全运行本体知识库,能够集中统一管理各种缆机安全运行知识,结合知识检索平台,可实现知识的高效查询和复用.
Abstract
In order to solve the problem that a large amount of multi-source heterogeneous structured and unstructured knowledge in the operation and management of cable crane is difficult to reuse,a large number of technical specifications,expert experience and other safety knowledge accumulated in the installation and operation and maintenance of cable crane were analyzed,and related entity classes of cable crane operation were extracted.A quintuple model was used to structurally express the safe operation of the ontology knowledge of the cable crane,and the binary relationship between classes was established.Then,the ontology expression language in Protégé was used to represent it programmatically.The ontology knowledge base of the cable crane entity,safety early warning and an emergency plan was constructed.3D scene model of the cable crane was constructed using 3Dmax software,and then the model was imported into Unity3D engine.Knowledge retrieval of the ontology knowledge base was realized through user interface design and interaction functions in the engine.At the same time,based on the existing examples of faults and accidents,the corresponding emergency plans were associated with the hidden dangers existing in each entity of the cable crane.Finally,a complete 3D visualization platform for safe operation knowledge retrieval of cable cranes was constructed.The results show that all kinds of safe operation knowledge of cable-winch can be centrally and effectively managed by constructing an ontology knowledge base,and a knowledge retrieval platform combined with an ontology knowledge base can effectively realize efficient query and reuse of knowledge.
