Design and realization of elevator control system based on PLC

Li Tao

Abstract

The application of S7-200 series Programmable Logic Controller (PLC) in the three-story elevator control system is introduced in this paper,and hardware and software design of the control system using PLC controller are given. Control system design plan,design process,system composition of three-story based on PLC are proposed,and a complete program of the elevator control system is designed,finally,the functions of system are validated on the three-story elevator model. From the results,it is shown that the system has function of no driver control,and is a high degree of security and reliability of the elevator control system.
