DESIGN AND ANALYSIS OF ELEVATOR CONTROL SYSTEM USING PLC

V. Balaji, G. Sudhakar

Abstract


An elevator is one of the important aspects in electronics control module in automotive application.For most people residing in urban cities, elevators have become an integral part of their daily life. Simply stated, an elevator is a hoisting or lowering mechanism, designed to carry passengers or freight, and is equipped with a carand platform that typically moves in fixed guides and serves two or more landings.This paper mainly
focuses on using programmable logic controller to control the circuit and building the elevator model. HallEffect sensor is used for the elevator position. DC Motor is used to control the up and down movement of theelevator car. Push buttons are used to call the elevator car. The elevator position is described by using thedisplay unit. In this paper, Auto Station Software ladder logic program is used for four floors control system.An elevator system is a vertical transport vehicle that efficiently moves
people or goods between floors of a building. They are generally powered by electricmotors. The most popular elevator is the rope elevator. In the rope elevator, the car israised and lowered by transaction with steel rope. Elevators also have electromagneticbrakes that engage, when the car comes to a stop. The electromagnetic actually keepsthe brakes in the open position. Instead of closing them with the design, the brakeswill automatically clamp shut if the elevator loses power.
Keywords: PLC, Elevator, DC Motor, TPLC Controller.
