Dual-channel Confirmation Scheme of Train Occupancy Based on Comprehensive Video Analysis and Its Implementation
The ZPW-2000 track circuit train control system for the entire Beijing-Shanghai HSR has integrated the capability of section occupancy logic inspection.Nevertheless,efficient technical measures for addressing fault occupancy and occupancy loss are lacking.To tackle this issue,the scheme of"dual-channel confirmation of train occupancy"was proposed.This involves extracting,merging,comparing,and analyzing track circuit data from the train control system and information from the integrated video surveillance system through an intelligent operation and maintenance management system.Algorithms for moving target detection and train following movement detection are employed for video analysis,while the YOLO v8 model is utilized to identify train types and section occupancy status.By conducting data fusion and comparative analysis of relevant systems,a dual-channel confirmation approach is established for track section status based on track circuits and field video feedback.This approach enhances the handling effficiency of fault occupancy and occupancy loss and improves the safety and reliability of train following movements.
