Automated Carwash Using Programmable Logic Control (PLC)

This paper presents development of Automated Carwash using Programmable Logic Control (PLC) Controller, for supporting their technologies and protocols. The main objective of the study is to reduce the volume of water use in car wash and to help to mitigate possible hazard from prolonged chemical response or any potential injury that might occur. In Kuwait, carwash is among the activities that consume a great deal of desalination water. The total intake for washing a single car is from 50-100 gallons of fresh water. The investigation shows that 75% of the water can be filtered and reused. As feed for the final rinse and make-up, an average intake of about 25% of freshwater is required. Due to the challenge in global economy, it is better to apply an automated process in carwash to reduce the human supervision and communication. In this work, PLC was activated according to its set process and used in achieving the automatic carwash system.
