A Control System Design for Hand Elevator Based on PLC

Abstract

The article analyzed the situation of elevator and the elevator industry in China. This paper proposes an idea that programmable logic controller (PLC) control the hand elevator, and discusses the specific structure of the system and the method of implementation. Meanwhile, this paper analyzed hardware and software of the elevator system, used reasonable hardware and software together to achieve the objective that move with the elevator automation and simplified the control circuit, and the method greatly improved the reliability and stability of the elevator.
