Abstract
The escalator provides great convenience for people's life. It is an indispensable means of transportation in major shopping malls and other public places. Therefore, we also put forward higher requirements for the safety and reliability of escalator control system. Firstly, this paper introduces the principle and characteristics of PLC control system, and compares the advantages of PLC escalator control system. Finally, this paper analyses the design requirements of elevator control system, and puts forward a kind of escalator control system based on PLC. At the same time, it describes the design scheme of hardware circuit, the specific main control system circuit and program control flow.
