Design and Development of Energy-saving Control System for Escalators Based on Intelligent Information Processing
Abstract: Currently widely used escalators are usually in a high energy consumption, serious mechanical wear, low efficiency and low service life condition. And there is a certain energy waste on the traditional escalator’ variable-frequency speed control system which adopts inpidual drive. According to the number of passages of shopping mall and subway station change frequently, the energy-saving control system for escalators based on common-DC-bus and the control method based on the traffic model are proposed to further enhance the use efficiency and energy-saving effect of the escalators. And combine those ideas an energy-saving control system for escalators based on intelligent information processing was designed. The energy-saving control simulation platform for escalator which based on intelligent information processing verified the feasibility of the design. Theoretical analysis shows that energy can be further saved by using the system.
