ADVANCED EMBEDDED AUTOMATIC CAR PARKING SYSTEM
The Project Automatic Car Parking System using 89S52 Microcontroller is an interesting project which uses AT89S52 microcontroller as its brain. The project is designed for car parking.
The aim of this project is to atomize the car park for allowing the cars into the park. LCD is provided to display the information about the total number of cars that can be parked and the place free for parking. Two IR TX – RX pairs are used in this project to identify the entry or exit of the cars into/out of park. These two IR TX – RX pairs are arranged either side of the gate. The TX and RX are arranged face to face across the road so that the RX should get IR signal continuously.
Whenever a car comes in front of the gate, the IR signal gets disturbed and the microcontroller will open the gate by rotating the stepper motor. The gate will be closed only after the car leaves the second IR pair since the microcontroller should know whether the car left the gate or not. Now the microcontroller decrements the value of the count and displays it on LCD. Thus, the microcontroller decrements the count whenever the car leaves the parking place and displays it on LCD.
If the count reaches ‘0’ and if any vehicle tries to enter the park, the gate will not be opened since there is no space. If any vehicle leaves the park, the controller will increment the count and allows the other vehicles for parking.
