PLC Based Tower Type Elevator Model for Automatic Car Parking System

Abstract

Manufacturers from several industries are gaining the advantage in auto machine technology in terms of productivity, flexibility, safety, accuracy and in reducing of manual efforts etc. Operating processes are designed in different modes of operation like manual, semi-automation and automation. Semi-automation and automation processes are controlled by different control devices like micro controller, PLC etc. Currently PLC is being used for many applications like industrial automation, traffic light automation, car parking automation, home application and many areas. This study presents the application of PLC (Programmable Logic Controller) in car parking automation. The aim of this paper is to make more advantageous method of car parking by using PLC application since the car parking is main problem in shopping malls, public traffic and scarcity of land in urban areas. Different types of car parking are currently available. A step beyond the existing scenarios is tower type parking. Car parking is proposed with three floors each floor can accommodate three cars the main components are PLC, sensors and elevator, BLDC motor and programming language is ladder diagram, software is TIA portal. Car is placed on the parking area sense by sensors and select the parkingin button it parks automatically in the vacant position and light the respected slot in the panel board followed by receiving a token number. For park out select the parkingout button and slot number the car automatically reaches to ground position.
