Research On Knowledge Modeling And Reasoning Of High Formwork Accident Based On Ontology

Facing the acceleration of the urbanization process,all kinds of buildings are rising from the ground,and the high formwork support technology has laid a good foundation for some new,special and different construction projects.But the accident rate of high formwork project is also high,in the case of a large number of accident control means proposed,high formwork accidents still occur from time to time,and cause casualties and economic losses.In the face of a large number of existing cases sleeping phenomenon,how to give full play to their maximum value,to provide guidance for the construction of high formwork project or the proposed project,to avoid the recurrence of similar accidents,reduce the accident rate is the purpose of this paper.Based on this,this paper introduces ontology technology and reasoning technology,which provides a new idea for high formwork accident control.In this paper,through the analysis of the theory of hazard sources,the cause mechanism of high formwork accident is proposed.On this basis,combined with the knowledge of high formwork field,the ontology model of high formwork accident is proposed.The hidden danger in the cause mechanism of high formwork accident is further analyzed from two aspects of human unsafe behavior and material unsafe state.Protege is selected as the ontology construction tool to complete the construction of high formwork accident ontology by defining class,attribute and instance.Case creation takes typical high formwork accident as prototype,runs pellet inference engine to check ontology,and realizes semantic consistency.According to the standard requirements of high formwork erection and the required procedures before the project starts,the important information and parameters are transformed into rules,and the high formwork accident control rule base is constructed with SWRL language.It is verified by two examples that the established rule base can judge the safety state of high formwork according to some parameters of high formwork support.If there is an unsafe state,corresponding control measures can be put forward for the existing hidden dangers,which has a function of event prediction.In this study,ontology technology is introduced into the field of accident control.The combination of high formwork accident ontology model and rule base has a certain practical significance for the reuse of domain knowledge and the pre decision of accident control.
