Control system design of adjust speed elevator based on programmable logical indecator

摘要

The control method and a stable operation of high-rise building elevators are currently hot spots of the programmable logic controller in elevator control research. This paper focused on five-story elevators, designs and implements a speed-regulation elevator control system using combination of OMRON CJ1M programmable logic controller and Yasukawa Inverter. Particularly, the elevator's function, operation, design ideas and programming are deeply discussed. The entire system includes external hardware design and control programming design. This system achieves a well control of speed-regulation of the elevator.
