The Design of Elevator Control System Based on PLC
Abstract: In the multi-storey buildings, the elevator is indispensable as transportation and is closely related to people's life, the elevator performance is good or bad is directly related to people's life quality. Elevator control system play a vital role in the whole process of elevator running. This design is an elevator control system designed by the PLC of Siemens S7-200 series, and the frequency converter change the elevator car speed, photoelectric encoder detecting the location of the capsules and convey it to programmable logic controller (PLC), after analysis and integrating, PLC sends out the signal and achieves implementation layer refers to the control of the elevator, inside the car and in each room of the station hall, elevator running direction instructions records and dock layer station control, automatic mode and automatic doors, and other functions through the control of traction motor, door motor and frequency converter. The result of the simulation indicated that the design of the system can realize the control request.
