This document presents details about an automatic car wash system project created by three students at Isra University under the supervision of Mr. Asif Javed Bajwa. It describes the components, working process, and advantages of the PLC-based system. The system uses a programmable logic controller and sensors to automatically move a car through five stages - shampooing, brushing, rinsing, drying, and exit. It is intended to save time, reduce hazards, and provide an efficient service for customers.

- 4. Why automatic car wash project? Save time Hazards free Society life style changing To provide efficient & reliable service Utilization of limited manpower Not too complicated ( customer friendly ) Environment friendly
- 5. COMPONENTS LIST Programmable Logic Controller Photo Electric Sensors Relays module Wiper motor Dc motors Led Lights Conveyor belt Water showers Brushes Dryers Terminal Block and Button
- 6. Components description Programmable Logic Controller : PLC is programmable controller device use to controller any system from remote area . Photo Electric sensor: A photoelectric sensor, or photo eye, is an equipment used to discover the distance, absence, or presence of an object by using a light transmitter. Relay Module: An electrical device, which is activated by a current or signal to open or close circuit.
- 7. Programmable Logic controller Mitsubishi I. Model: FX1S30MR II. I/O : 30 I/O III. Number of Inputs 16 IV. Number of outputs 14 V. Programming Language Used Ladder Logic VI. 512 auxiliary relays, 64 timers, 32 counters, 256 data registers
- 8. Components Description. DC motor: A DC motor is a class of electrical machines that converts direct current electrical power into mechanical power. I. Speed: 100 rpm II. Voltage : 12v DC III. Power : 3 watt IV. Current: 300mA Wiper motor: Gear motors used with conveyor belts that use a very low rotational output speed to create incredible amounts of torque. I. Speed: 30 rpm II. Voltage: 12v DC III. Current: 7 A
- 9. Components Description: Conveyer Belt: Conveyer is mechanism which will carry the car. Water sprinkle : It will use for showering the water and shampooing over the car Water Pump: It will Suck the water ,shampoo and it will spraying by water sprinkle
- 10. Five Stages 1. Initial Stage 2. S1 (Working of Sensor one) 3. S2 (Working of Sensor Two) 4. S3 (Working of Sensor Three) 5. S4 (Working of Sensor Four)
- 11. Sensor ONE Detect the car Give signal to the PLC in form of 12 v Stop the wiper Motor Allow Pump ONE to sprinkle Shampoo and water Allow to sprinkle for time frame given Limited time delay After the time delay the Wiper Motor start again and convey the car to next stage
- 12. Sensor TWO When the Car reach the Sensor 2 Detect Stop the Wiper Motor Allow the Brushes to cleaning through the rotation With in time frame After the Given Delay time the Wiper motor start again and conveyer move the care one step Ahead
- 13. Sensor THREE When the Car reach the Sensor 3 Detect Stop the Wiper motor Allow pump TWO to sprinkle clean water . For washing After given time the Wiper motor start again and forward the car to next stage
- 14. Sensor Four When the Car reach the Sensor 4 Detect it Stop the wiper motor Allow to ON dry fans After the time frame the fan stop Wiper motor start again and moving forward to Ending Point Done and system stop their all process
- 15. CAR WASH FLOW PROCESS Start Registration & payment with supervisor Declare what type of service need Bring customer’s car to washing platform Perform desire services Customer can take their car Finish
- 16. WORKING Sensor 1 detects the car stop the conveyor and allow Pump 1 open to spray Shampoo Pump 1 open & sprays shampoo on car on limited delay After delays car move sensor 2 detects it Conveyor will start move Brush starts work on car After delays car move sensor 3 detects it Pump 2 open & sprays clean water After delays sensor 4 detects the car Dryer starts work & dry the car After delays car move Sensor 4 detects the car And car exit from exit door

- 20. ADVANTAGES Less Area required Less time requirement in operation Less man power requirement Pollution free Easy to operate Standards parts and components are easily available Can be use in domestic service stations Very less maintenance
- 21. LIMITATIONS Primary investment is high More amount of water is required System installation is complex
- 22. TARGET AUDIENCE Supermarkets & malls GAS stations Railway stations & Air ports Hotels Resorts Theaters & universities Public places & private companies
- 23. SWOT ANALYSIS STRENTH Fast services Great quality service Modern technology & machine Skilled worker Easy access Wash up to 50 cars per hour THREATS Competitors The biggest carwash company from foreign country is our threat if they coming to make business near by us. OPPERTUNITIES Busy car owners WEAKNESS Quite high cost for operation A little high price from competitors according to our quality service and our high technology equipment.
- 24. FUTURE ENHANCEMENT Interior wash Under chases wash coin or token system Also we can implement a counter which will be allowing the number of cars washed to be counted
- 25. CONCLUSION After Woking on this automatic car wash , we can came to conclusion than such automation system are: Quite beneficial Saving time of operation Man power reduced Improving the economy of the system In the future such type of automated systems will have more demanded.
