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

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.
