DEFINITION

Parking of cars in a parking area is becoming a difficult task as the number of cars increases while the number of parking spaces is finite.

People spend a certain amount of time looking for parking spaces and thus traffic slows down and cause congestion.

The information of available parking spaces is not readily available to the people looking for parking spaces.

INTRODUCTION

The project portrays the idea of automated parking system.

Movement of the vehicle is controlled through the sensor inputs using a PLC.

Sensors and the programmed PLC simulates the eye and brain of a human respectively.

The vehicle is parked and retrieved without human intervention.

HISTORY

The earliest use of an APS was in Paris, France in1905. The APS consisted of a groundbreaking multi-story concrete structure with an internal elevator to transport cars to upper levels where attendants parked the cars.

In the 1920s, forerunners of automated parking systems appeared in U.S. cities like Los Angeles, Chicago, NewYork and Cincinnati. Some of these multi-story structures are still standing, and have been adapted for new uses.

 A system that is now found all over Japan —  the Ferris-wheel, was created by the Westing house Corporation in 1923.

 The Nash Motor Company created the first glass enclosed version of this system for the Chicago Century of Progress Exhibition in 1933, and it was the precursor to a more recent version, the Smart Car Towers in Europe.

PLC

• PLC - programmable logic controller

• A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on.

• PLC implements logic control functions by means of a program.

PLC COMPONENTS

There are five basic components in a PLC system:

1. The PLC processor, or CPU.

2. I/O (Input /Output) modules.

3. Bus System.

4. Programming software that runs in a PC.

5. Power supply.

PLC OPERATING CYCLE

• Four Steps in the PLC Operations

• Input Scan

• Scan the state of the Inputs

• Program Scan

• Processes the program logic

• Output Scan

• Energize/de-energize the outputs

• Housekeeping

• This step includes communications, Internal Diagnostics, etc.

• The steps are continually repeated - processed in a loop.

DELTA PLC

SCADA

• SCADA is “Supervisory Control and Data Acquisition” – real time industrial process control systems used to centrally monitor and control remote or local industrial equipment such as motors, valves, pumps, relays, etc

• A SCADA system gathers information (such as where a leak on a pipeline has occurred), transfers the information back to a central site, then alerts the home station that a leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion.

SCADA VIEW

DC GEARED MOTORS

Geared DC motors can be defined as an extension of DC motor. A geared DC Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed.

APPLICATION AND PURPOSE

Solves the problem of parking in shopping complex, public place or apartments.

It can be used in automobile servicing centers.It can also be used in automobile manufacturing industry.The parked cars and their contents are more secure since there is no

public access to parked cars.Minor parking lot damages such as scrapes and dents are eliminated.Driving around in search of a parking space is eliminated, thereby

reducing time and fuel consumption.
