Based on Single-Chip Adaptive Fuzzy Algorithm Escalator Energy-Saving Control System

To solve the problem caused by the inherent design of AC motor that 20%~40% energy of traditional escalator goes to waste in vain in the form of heat, this paper puts forward to the best control project of the escalator energy-saving control-adopting instantaneous detect technology, single-chip control, intelligent control system with speed control and voltage control and frequency converter, based on adaptive fuzzy algorithm to diagnose the fault of the escalator, detect dynamic state person (two class) by single-chip control, automatic transformation escalator frequency converter controller´s work method like speed control and voltage control, and safety monitor protection circuit to optimize the performance of the escalator. The practice shows that energy can be saved more than 40% by this system.
