ABSTRACT

The increasing number of cars and the ever-decreasing amount of free space makes searching for parking place very difficult, especially in metropolitan areas. This does not just apply to cities, urban areas and business parks, but also to office buildings, airports, train and subway stations, trade centers and hotels. Parking is increasingly becoming the deciding factor for companies who are looking to re-locate or build to suit.

There are over 550 million cars on the road worldwide, and this number is increasing at a rate of more than 5% annually. As the number of drivers grows, so does the demand for convenient and safe parking. Automated parking, a method of automatically parking and retrieving cars, solves these and many other parking problems.

INITIATION FOR OUR AUTOMATIC SYSTEM

Finding parking spaces in urban areas is becoming more and more difficult as the number of vehicles significantly increases every year. The scarcity of parking space also limits the opportunity to expand existing residential and office buildings, hotels, private and public parking facilities.

So our project aim is to build a garage for twice as many cars in the same amount of space or uses much less space (up to half the amount) for the same amount of cars. Therefore, our parking solutions will facilitate the reduction of operating costs.

Also people finding difficulty to protect their cars from theft, when they park the car.

Automation is a technology concerned with the application of mechanical, electronic, and computer based systems to operate and control process.

Compared to present all other auto car parking system, our proposed model possesses better advantages in terms power consumption by system, time of parker and security, with cost effectiveness.

Pin Configuration of 89C52

Internal Architecture 0f 89C52

USE OF 89C52

• Controlling unit.

• Storage unit.

• Processing unit.

Model in Detail

USE OF PORTS

•Port 1 – Data lines for LCD.

•Port 2 – Motor excitation.

•Port 3.0 & 3.1 – Control lines of LCD.

•Port 3.6 & 3.7 – Address lines of EEPROM.

STEPPER MOTOR

A unique type of motor is the STEPPER MOTOR. Instead of rotating smoothly around and around as most of the motor do, stepper motor rotates from one position to the next when pulsed. Common step sizes range from 0.9 to 30 degree. Steppers might be through of as “digital” motors. A stepper motor is step from one position to the next by the proper combination of fields in the motor. The drive sequence can be produced by connecting the switches to the outputs of a 4 – bit ring counter.

Stepper Motor Circuit

Features of Motors

• 250mA/winding for 1Kg Torque Motor.

• 1A/ winding for 2Kg Torque Motor.

• 12V Stepper Motors.

Liquid Crystal Display

Frequently an AT89C51 program must interact with the outside world using input and output devices that communicate directly with a human being. One of the most common output devices used is a LCD. Some common LCD’s are 16x2 and 20x2 displays,

Which mean 16 characters per 2 line and 20 characters per lines, respectively.

 

Power Supply Circuit

Power Supply Description

Bridge rectifier is use to get 12V output to the stepper motor. Bridge rectifier uses the diode

6A4 of the current rating 5A. Voltage regulator 74L805 use to give voltage of 5V to micro

controller and other electronic

SERIAL EEPROMS

WAY TO OUR MODEL

FEW EXISTING MODELS

It Will look like this……

RESULT

• Effective utilization of empty places, since bi directional movement of lift.

• User friendly.

• No ambiguity procedure.

• Less maintenance, with less power consumption.

• More secure.

APPLICATION

• This can be applied even in developed cities, where people face scarcity of place in small countries.

• In shopping complexes, Hotels, Apartments.

• In public places like Airports, Hospitals, Railway Stations, In famous visiting places where people find difficulty to park.

CONCLUSION

• This can be implement in small areas.

• This model works by using low power compare all other models.

• Parker time can be saved by fast parking and exiting.

• More security, in terms of Smart Card

• Less initial investment, no human security.
