This paper introduced the energy saving potential of escalator in the metro transit system and analyzed the influence factors of the real- time passenger flow in escalator system. This technical scheme based on the real - time control of the escalator passenger flow was studied. The control scheme of the energy saving was designed basing on passenger flow during peak hours and off- peak hours. Given mathematical model for the scheme practicability and designed the corresponding program. The simulation results of the power consumption under both rated speed and frequency conversion control show that the technical scheme based on the real time passenger flow has energy - saving effect. Lastly, three kinds of control schemes and their energy - saving effects were compared and analyzed and the superiority of application in different passenger flow was expressed.
