XXX: Design of Elevator Control System based on PLC
Abstract:
Currently。there are three main control methods for elevator
control systems: relay control system。PLC control system。and
puter control system。Due to its high reliability。easy
maintenance。strong anti-interference ability。short design and
debugging cycle and other advantages。the PLC control system
has e the most widely used control method in elevator control
systems。Based on the structure of the elevator and the structure
and working principle of the programmable controller。this paper
focuses on the design of a four-story elevator control system using
Siemens S7- programmable controller.
