CONTENTS
In the project “Car Parking System” we have shown the concept of an automatic car parking system which will automatically sense the entry & exit of cars through the gate and then display the no. of cars in the parking lot.
The sensing of entry and exit of cars is done with the help of Infrared transmitters and receivers.
Introduction:
Block Diagram of The Project
Powered by +5V & +12V supply Current consumption 0.45mA for
Microcontroller circuit, 0.75mA for switching circuit, 200mA for amplification circuit
Automatic detection of any incoming/outgoing car
Automatic opening and closing of entry gate User interface using LCD and switches Always display the number of cars present
in the Parking Lot
Features of Project:
Power supplies are designed to convert high voltage AC mains to a suitable low voltage supply for electronics circuits and other devices. A power supply can be broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:
Power Supply
Transformer – steps down high voltage AC mains to low voltage AC.
Rectifier – converts AC to DC, but the DC output is varying.
Smoothing – smoothes the DC from varying greatly to a small ripple.
Regulator – eliminates ripple by setting DC output to a fixed voltage.
Each of the block has its own function as described below
AT89C51 microcontroller used in this project.
It is MTP(Multi Time Programmable) IC. Hardware Featurea) 40 pin ICb) 4Kb of Flashc) 128Bytes of RAMd) On Chip Oscillator and Clock Circuitrye) Two 16-Bit Timer/Counter
Microcontroller
The LCD, which is used as a display in the system, is LMB162A. The main features of this LCD are: 16*2 display, intelligent LCD, used for alphanumeric characters & based on ASCII codes.
The LCD containsa) 8-pins are used as 8-bit data I/O.b) 3-pins are used as control lines.c) 2-pins are used as backlight & LCD
voltage.d) 2-pins in backlight & LCD ground.e) 1-pins is used for contrast change
Display Unit
The 555 timer is used in the Infrared transmitters and receivers. At the transmitter it is used to produce a pulse of 38 kHz. This pulse is then fed to the Infrared LED so that it produces bursts of Infrared energy at the rate of 38 kHz. The reason of transmitting frequency being this much particular value is that the Infrared receiver (i.e. TSOP 1738) works at maximum efficiency when the Infrared rays falling on it, are of 38 kHz.
Intruder
The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation.
The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence.
Stepper Motor
1) This project can be used for parking system in any shopping mall, multiplex
2) Can be used for industries, commercial offices and educational institutes.
Applications and Advantages:
By the end of this project
Connections and testing in Proteus is studied. Coding and compiling of a C program in Keil Vision
software is studied. Hardware implementation by connecting Schematic
and making Board layout EAGLE is done successfully. The hardware kit is tested successfully by
embedding the C program – Hex file in the AT89C51 Microcontroller.
The operation of microcontroller is analysed in simulation and practically.
