Research on situation deduction for railway passenger station safety based on digital twin
In order to grasp the safety change trend of railway passenger station in real time,the digital twin technology was introduced into the field of passenger station safety management.Through designing the framework for situation deduction of passenger station safety,a four-layer deduction system including the safety situation awareness model of passenger station safe-ty awareness,understanding and prediction and the safety results was established,and a framework for situation deduction of passenger station safety based on digital twin was designed.According to the boarding process of passenger as the main line,the change in the coordinated actions among station personnel,equipment,trains,and operations during both routine and emergency scenarios was extracted,then a digital twin collaborative action behavior model of the station was formed,and the mirror image reflected the deduction process of passenger station safety situation.Taking the flood event of a passenger station as a typical case,the specific content of the cooperative behavior of the situation deduction was refined.The results show that the effectiveness of digital twin technology in safety situation deduction of Qinghe station is verified from three twin indexes:appearance fidelity,data acquisition accuracy and process simulation loyalty.The research results can provide strong technical support for the safety management of passenger stations.
