Construction, as a significant production activity, is inherently prone to accidents. These accidents often result from a chain of multiple hazards. However, existing methods of hazard analysis are limited to single-dimensional network modeling and static analysis, which makes them inadequate for addressing the complexity and variability of construction sites. This paper presents a dynamic construction hazard analysis method that integrates real-time information into knowledge graphs. In this approach, label entities are added to general knowledge graphs, linking hazard entities to their labels. Labels identified through vision-based methods are then incorporated into the graphs, allowing for the effective extraction and updating of subgraphs in response to spatiotemporal changes in the scenario. Additionally, graph analysis metrics have been proposed to evaluate the system from multiple levels. Finally, the method was applied to a bridge foundation construction case, demonstrating its practicality and significance in preventing accidents by enabling dynamic hazard analysis.

使用与实时信息集成的知识图谱对建筑工地进行动态危害分析



建筑作为一项重要的生产活动,本质上容易发生事故。这些事故通常是由一系列多重危险引起的。然而,现有的灾害分析方法仅限于单维网络建模和静态分析,这使得它们不足以解决建筑工地的复杂性和可变性。本文提出了一种动态施工危险分析方法,该方法将实时信息集成到知识图谱中。在这种方法中,标签实体被添加到一般知识图谱中,将危险实体链接到其标签。然后,通过基于视觉的方法识别的标签被合并到图形中,从而允许有效地提取和更新子图以响应场景中的时空变化。此外,还提出了图形分析指标,用于从多个级别评估系统。最后,将该方法应用于桥梁基础施工案例,通过动态灾害分析证明了该方法在预防事故方面的实用性和意义。
