Abstract
Elevator is the vertical vehicle of modern high building,which has close relationship with the life of people.The elevator developed very quickly with the increasing demand of people.The drag of elevator developed to use the frequency conversion and voltage transformation to realize the speed regulation.The logic control of elevator is accomplished by PLC instead of relay control.The article uses the PLC to control the elevator based on existed current frequency transformer.Through the resonable choice and design,we can increase the control level of the elevator,and improve the safety and comfortable feeling of elevator,and obtain perfect contrl effect.
