Research on Urban Rail Transit Train Autonomous Perception System and Key Technologies

The combination of modern sensors, artificial intelligence and automatic operation systems provides novel approaches for urban rail transit to transform from automation to intelligentization. The concept and purpose of urban rail transit autonomous perception system is proposed, and the structure, building blocks and key technologies of the system are elaborated. Results show that autonomous perception system can fully comply with urban rail transit operation scenarios, effectively exerting advantages of various sensors and algorithms in environmental perception, supporting the improvement of safety and operation efficiency of the system, further making use of the merits of urban rail transit format.
