3.  TWO TYES OF CAR PARKING
 TRADTIONAL
 AUTOMATED
 REQUIRES LESS SPACE IN AUTOMATIC CAR
PARKING
 REDUCES POLLUTION
 TRADTIONAL CAR PARKING IS COSTLY
PROCESSS
 USES 8051 MICRO CONTROLLER
 USED TO OVERCOME TRAFFIC PROBLEMS

6.  In 1920 automated car parking in U.S cities
 Los angles, new york , chicago
 This system is found all over Japan in 1923
 The nash company created first glass
enclosed version in 1933.
 In later years in Europe as smart car towers
 In 1983 Kent automated parking garage was
built in new york
 Developed in 20th century.

7.  Parking system is based around micro
controller and sensors
 This process is quick and efficient.

8.  Stepper motor
 Stepper motor is a digital device
 It follows the instruction as the computer does do
 It is used for the movement of lift
 U-SHAPED PHOTO SENSORS
 The anode of IRED is connected to the power supply via the.
 The resistor adjusts the irradiance by limiting the forward current
of the IRED.
 If an object is moving between the gap the light will be blocked
and the transistor base will on, hence give an high output.

10.  SEVEN SEGMENT DISPLAY
 Used for displaying numbers and some letters
 Microcontroller Port2 is use to handle the display unit.

11.  Serial Interfacing:
This unit is to display the number of cars in parking lot on the
computer.
 The computer may be placed in any control room.
 In null modem mode pin 7,8 and pin 6,4 are shorted with each
other.
 While pin 3 is used for transmit data and pin 2 for reception

12.  The 8051 is the brain of this whole hardware.
 It reads the input signals and start sending the stepping sequences to the
motor.
 When the input beam of S1 is blocked motor start rotating in clockwise
direction.
 S1 indicates that a car has come.
 The S2 sensor is used as the gate open limit sensor
 when S2=ON it means gate is completely opened.
 motor start rotating in counter clockwise direction, closing now.
 Finally, when S3=ON it indicates that gate is completely closed now.
 A display is provided at the ground floor that displays number of cars in
each floor.

13.  An indicator with a green and red LED is kept in all the floors.
 Indicate whether the lift is busy or is it ready to take the car up or
down.
 seven segment display indicates that a car has entered in the
parking lot.
 This display is basically for the people, which are driving the car.
 serial interfacing display is for the person in control room.

14.  LiftBox Type
 Park Type
 Z Park
 ELEPARK
 Elegant Park
 Round Type

16.  No digging required.
 No Hydraulic parts.
 Electric device
 Reliable & smooth operation.
 Requires minimum Maintenance.

18.  Over 5,000 parking systems in use worldwide.
 Less Pollution
 Security from Theft and Car Damages
 Save you space, time & money
 Simple structure, simple operation
 Speedy system, moves smoothly, not noisy.
 It can be constructed and implemented in
residential areas.

19.  Parking lots also tend to be subject to
contamination.
 concentrated spots of pollutants such as
motor oil.
 preferred shaded parking spaces in the
summer.
 planting trees because of the extra cost of
cleaning the parking lot .

20.  Important factor in traffic areas
 Automated without human being
 Stepper motor plays a vital role
 Seven segment display is used at every floor
 Sensors are used for sensing the car
 This system is present in DELHI, MUMBAI,
BANGLORE
