A non-ticket personnel dynamic tracking method and system for a construction site

Abstract

The application discloses a construction site-oriented non-ticket surface personnel dynamic tracking method and system, comprising: collecting information data of personnel entering a construction site and comparing with a construction ticket surface roster to screen suspected non-ticket surface personnel; establishing a heterogeneous graph based on information data of the suspected non-ticket surface personnel and information data in a ticket surface personnel database, and performing aggregation of local similar nodes based on the heterogeneous graph to identify target non-ticket surface personnel; obtaining a motion trajectory of the target non-ticket surface personnel, calculating a deviation degree based on the motion trajectory of the non-ticket surface personnel, and obtaining a trajectory deviation degree index of the target non-ticket surface personnel; constructing a behavior causal diagram model based on the trajectory deviation degree index, discriminating a behavior state of the target non-ticket surface personnel based on the behavior causal diagram model, and generating a behavior risk discrimination result; and generating a risk level label based on the behavior risk discrimination result.
