Water Recycling Car Wash System Using PLC

Download Project Document/Synopsis

Car wash systems allow for fully automated car wash in a short amount of time. Here we demonstrate a smart PLC based car wash system that allows for completely automated car washing process. The system consists of a 4 stage car wash system. The system consists of a small conveyor type belt that holds on to a car. The system has a IR sensor to check if a car has been parked in the system. On detection the system now starts the belt movement using a motorized system and vehicle moves to the first stage. This stage has a preliminary sprayer that sprays water on the car and passes it to the next stage. The next one is a spinning brush system that spins dual brushes to further clean and wipe the vehicle. The next stage is s dual sprayer that sprays water from top as well as bottom to wash the car from both sides. The belt now takes the car to the last step there we have DC fans to dry up the vehicle after the wash. The system allows for an automated car washing process using PLC to detect vehicle and control its movement at each step. The water poured on vehicle is collected under the mesh of the system and is passed through a filter to reuse for the next wash, thus saving a lot of water unnecessarily wasted in car washes.
