摘要
本文在介绍电梯基本结构的基础上,阐述了电梯的拖动原理和控制原理,研讨基于PLC和变频器的VVVF电梯控制系统的实现方案,设计出了采用PLC进行逻辑控制的变频器调速集成电梯控制系统。
This paper,based on the introduction of the elevator or basic structure,expatiates the drive and control principle of elevator.The implementation project of elevator＇s VVVF control system based on PLC and transducer is studied and proposed.This article was precisely has carried on the improvement design in view of these questions to the existing elevator system.Uses PLC to carry on the logical control,modulates velocity the elevator control system with the frequency changer.
