In this paper,the author puts forward a brand-new circular shuttle bus control speed door,aiming at solving the problems of safety hazards and high energy consumption existing in the traditional speed door when the circular shuttle bus enters and exits.The author optimizes the structural design and control system of the door,realizes the safe and efficient access management of the circular shuttle bus,and saves a lot of energy.The author introduces the design idea and implementation method adopted in this study in detail,and verifies its performance and reliability through experiments,thus improving the efficiency of the entry and exit of circular shuttle bus,reducing potential safety hazards,and making contributions to environmental protection and energy conservation.
