Abstract

As the economy of a nation is getting stronger, more people can afford to buy their own cars. This is a common situation in developing country such as Malaysia. The increase number of car owners had causes problems such as road congestion and difficulties in parking the car due to limited number of car parks or parking lots. Example of these conditions can be seen in large cities or towns. One example of a conventional car park is by reserving a big piece of land where all the parking lots are on the ground level outside a building. Another type of conventional car park is the multi storey car parks where it is build underground or above the ground intended to reduce parking space. The weakness of these existing parking systems is that it requires the car drivers a lot of time to search for an empty parking lot hence wasting the car’s fuel. In some modern countries, they had already developed an alternative to counter this problem by building an automated parking system. The system will automatically park the car into the parking lot without being accompanied by the driver or passenger. The driver will enter a garage and leave the car there for the system to do the parking. Then, when the car owner want to retrieve their car, they will command the system to automatically sent there car back into the garage so they can exit the car park facility. In this project, a model of a parking system by an application of programmable logic controller (PLC) will be developed. The purpose is to give an overview on how a PLC works to control and automate a given system, in this case the parking model. The study will begin by understanding the basics of PLC and then applying the knowledge in automating the mechanism of the parking model. When the model is completed, analysis such as model operation analysis and emendation of the PLC ladder diagram will be carried out until the desired operation is achieved.
