3. SMART CAR PARKING SYSTEM
Automatic multistoried car parking systemhelps to minimize the parking area. In the
modern world where parking space has become a very big problem, it has become very
important to avoid the wastage of space in modern big companies and apartments etc.
in places where more than 100 cars need to be parked, this system proves to be useful in
reducing wastage of space. This automatic car parking systemenables the parking of
vehicles, floor after floor and thus reducing the space used. Here any number of cars
can be parked according to the requirement. These makes the system modernized and
thus space-saving one. This idea is developed using 8051 microcontroller.
1 THEORY OF PROJECT
A display is provided at the ground floor which is basically a counter which will count
the number of cars in each floor and according to that message will be displayed on it. A
gate is also provided at the ground floor which is controlled by the stepper motor.
Before the gate an IR pair is provided to sense that the car has reached towards the
gate. For e.g. suppose a car reaches between the 2 IR pairs, then the LCD will display
the particular floor on which car can be parked. As soon as the car crosses the 2nd
IR
pair, the gate will open automatically. An indicator with green and red led is kept on
each floor to indicate whether the car can be parked on that particular floor or not. If
green led of any particular floor glows, then it will indicate that the particular floor is
empty and you can park your car on that floor. But in case if red led of that particular
floor glows, then it will indicate that there is no vacancy on that floor, in such case you
can park your car on the next floor according to the indication.
If there is no parking place, then all the red indicators of the floors will glow and the
LCD will display “NO SPACE FOR PARKING” and the gate will remain closed.
Program is written using 8051 microcontroller. All the circuits are interfaced with it.
2 ADVANTAGES OF MULTI-STORY CAR PARKING:-
Any like Newyork, Delhi, London has over five million cars and two-wheelers on its
roads, but not enough parking spaces. The demand for parking space has, on an
average in the main markets of Delhi, outstripped demand by 43 per cent. It is not just a
problem of Delhi or Mumbai; all the big cities in India are facing the space crunch.

4. Parking space is fast becoming a major issue in other cities like Kolkata, Bangalore,
Hyderabad, Ahmedabad, Chandigarh, Pune and other urban and semi-urban cities.
Multi-storey car parks provide lower building cost per parking slot, as they typically
require less building volume and less ground area than a conventional facility with the
same capacity.
A multi-storey car parks offer greatest possible flexibility for the realization of optimum
parking solution. Time-saving vertical and horizontal movements take place
simultaneously ensuring fast parking and retrieval times.
3 DISADVANTAGES OF MULTI-STORY CAR PARKING:-
Drivers who use multi-story parking facilities, sometimes known as parking garages,
often enjoy a number of benefits the structures provide. Despite the ability of the
garages to house a large number of cars, multi-story parking facilities also carry a
number of distinct disadvantages that arise from their tall, enclosed and often dimly lit
nature.
1.Deterioration and Maintenance
Multi-story parking facilities support hundreds of thousands of pounds of vehicles,
people and equipment every day. Because the garages support very large amounts of
weight and loads that constantly change, the structures quickly deteriorate in the
absence of constant maintenance activity. In addition, according to Canada’s National
Resource Council, changing weather and environmental conditions can deteriorate a
garage’s steel support structure, creating an unsafe environment for garage users. A
number of corrosion inhibitors can help delay processes that eat away at the structure’s
integrity, according to the National Resource Council, but constant maintenance and
upkeep must include anti-corrosion measures to keepmulti-story parking facilities
structurally sound.
2.Parking Angle Considerations
Because many drivers of varying levels of skills and experience drive in, around and out
of parking garages every day, designers must pay special attention to the configuration
of parking spaces within the structures. In a municipal parking garage presentation
prepared by architects Sakri and Khairuddin, the designers noted that two-way traffic
flow in a multi-story garage presents a number of parking challenges for drivers and

5. designers. Parallel parking, for example, creates an inefficient use of limited space,
while straight parking spaces make parking difficult for some drivers. Other options,
like angled parking, do not work well with a two-way traffic flow and can only work
well in garages with separate entrance and exit openings.
3.Safety
Because multi-story parking facilities allow limited natural light inside, some security
experts express concern about safety inside the structures. In their municipal
presentation, architects Sakri and Khairuddin recommend security devices that directly
connect to local police or public safety stations. In addition, the architects explicitly
describe a need to reduce dark places where criminals may hide. Even with security
measures in place, though, criminals still seemto thrive in multi-story parking
structures; in a 2009 article in the Chicago Sun-Times, one parking garage user
expressedfrustration after experiencing three burglaries within two years.

7. ABSTRACT
The Project Automatic Car Parking System using 89C51 Microcontroller is an interesting
project which uses 89C51 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 the mains are switched on, the LCD displays the
message"parking space for 10 vehicles". The number indicates the maximum capacity of park
in this project. 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. In this way, the microcontroller decrements the count whenever the car leaves the
park and displays it on LCD. lf the count reaches'0', i e. if the park is completely filled, the
microcontroller will display"NO SPACE FOR PARKING" on LCD. And now 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 This
project uses regulated 5v. 500mA power supply. Unregulated 12v DC is used for relay. 7805
three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier
is used to rectify the ac output of secondary of 230/12V step down transformer

13 3 MAJOR LIET
Industrial type prefabricated park-lifts can be used by Municipalities in high- traffic city
centers to deminish traffic caused by parking-space searching cars and increase parking
capacities Increase the car parking capacity of your office building. At an auto gallery to
demo more cars to get extra attention at the showroom. At a pay parking lot to increase the
capacity of the premises. At a city centrum hotel garden, airport, shopping mall to increase
the parking capacity Cars at a parklift is extremely secure. Getting extra space is major
advantage but there are other advantages: Cars much safer at the parklift against burglary or
theft. The chance of getting hit by other cars up above is simply none. Systems can be used
indoorsor out Needs almost no maintenance. Just like the Opti-lift Major lift is a dependent
type parking mechanism: Please review files at related downloads" section at the bottom of
this page. Hot dip galvanizing of all steel components protects these lifts for life.

5.HIGH – LIFT

18. They are engineered to lift motor vehicles for parking purposes but also suitable for car
dealers to use as a showcase with glasscover around the steel construction. Structural
Analysis for these lifts has been carried out in accordance with UBC-97(Uniform Building
Code) & AscE-7(American Society of civil Engineers) with EQ and wind loads taken into
consideration. Systems are approved by City of New York Dept. of Buildings. During
manufacture, these units are sand blasted, treated with an anti-corrosion coating and then
painted giving a long operational life.. 4 highs and 3 highs come in 2 different height
versions for sedans and suvs.
1.MULTLPARKING
Because each elevator and cart is operated independently on each level, entry and exit is
quick. Retrieval time of a vehicle is less than two minutes.
Low noise and vibration. Elevators never touch guide rails, use of urethane rollers
minimize noise when transferring pallets from elevator to carts and then to parking slot.
Entry and exit is very quick and convenient. We incorporate a built in turntable on each
elevator.
Completely equipped with multiple sensors and triple safety devices. A self malfunction
diagnostic control provides you with an excellent level of safety and reliability.

19. The Multi-Parking system has been designed to automatically move the vehicles by lift
which then transfers it to a waiting cart on one of the multi-levels. The carts then travel
horizontally and place the vehicle in its appropriate slot. This system is suitable for
middle and large-scale buildings as well as independent public parking garage. The
multi-parker can accommodate as little as 20 vehicles to several thousand units. It is
therefore suitable for large scale projects. It can move more than 2 vehicles at the same
time for maximum efficiency

20. 2. TOWER PARKING
Minimal land use. An area of 7mx7m can park up to 50 vehicles. Low noise and
vibration. Elevators never touch guide rails, use of urethane rollers minimize noise
when transferring pallets from elevator to storage Entry and exit is very quick and
convenient. We incorporate a built in turntable on the elevator and retrieval time is
less than two minutes. Completely equipped with multiple sensors and triple safety
devices. A self malfunction diagnostic control provides you with an excellent level of
safety. Has the capability of holding cue memory when multiple patrons come to
retrieve there vehicles during rush hours. The elevator type often called the Parking
Tower, is designed to automatically move the vehicles on a pallet vertically on the
elevator, it then transfers it horizontally left or right for storage. Very fast retrieval
time is accomplished in less than two minutes. This system is suitable for medium or
large scale buildings. It can also be used as a stand alone tower for a parking garage
business. Since it is controlled by an integrated computer system, the overall
operation can be viewed with one screen and its operation is very user friendly. We
incorporate German motors and components are used in every system by world
known SEW Eurodrive.

22. 3.SQUARE PARKING.
With eight times the space efficiency of a ramped garage, this system can use the
narrow basement spaces to its maximum capacity. Up to six levels can be equipped
with this new technology With the adoption of the high speed lifting mechanism, the
elevating speed has become very quick, thereby significantly shortening the time
required for entering and leaving With our upper entrance design, it is convenient
because the built-in turntable allows for easy entry and exit. After entering the
vehicle in the parking garage, the parking system is designed to move the vehicles
vertically with elevators on each end. The garage consists of several levels where the
vehicles are moved horizontally which rotate the pallets in conjunction with the
elevators. The multi floor circulation type is suitable for small and mid-sized
buildings because of its high space efficiency.

24. 4 Puzzle Parking in 2.3, or 5 HIGH versions
Independent parking The top layer pallets can move up and down lower layer pallets can
move either left to right or up and down. Max time to retrive cars is 60 sec with 2& 3
high systems and 90 sec with 4& 5 High systems PLC control. easy operation, push
button lifting with chain at 2& 3 highs and steel cables at 4& 5 High systems Built in
drop protection, prevents failure and accidents. photoelectric checking system which
controls vehicle size Emergency stop pushbutton Steel construction with complete
galvanization Safe operation, low maintenance

26. WORKING
The initial condition for the lift is at ground. At the ground controller always check for
the car to park and to retrieve car. Car Parking Parking process starts with the car enters
in the slot. Each floor consist of two sensors, upper extreme& lower extreme to set/stop
the position of the lift A display is provided at the ground floor which is basically a
counter that displays number of cars in each floor. It informs whether the floors are fully
filled with the cars or is it having place in a particular floor or not. There is facility of lift
to carry the car to up and down. Movement ofLift is controlled by stepper motor. When
the lift reaches the first floor, the processor compares the filled amount to that of the
already fed capacity of that floor, and if it finds that the first floor is fully filled, it goes
to the second floor and thus the procedure stops here. As soon as a car is placed in a
particular floor, the display counter at the ground floor increments as to indicate the floor
capacity has decreased by one. After the lift places the car in a particular floor, it comes
back to its normal position and that time, the motor that drives it also stops. When a
person needs to come down from a particular floor to ground floor, he is expected to
focus the headlight onto the LDR placed in that floor. Now sensor section sends signal to
motor that the lift has to be send back to that particular floor and sends a signal to glow
RED LED indicating that the lift is busy. As soon as the lift reaches that particular floor
car should come inside the lift, the display counter at the ground floor decrements by one
as to indicate the floor capacity has increased by one. Lift comes back to its normal
position and the that time, motor that drives it, also stops.

27. LITERATURE REVIEW
This article by Smith and Roth(2003), talks about how advanced Car Park techniques are
being implemented using the SMS services available on cellular phones. It describes how
useful these advanced car parking systems are in providing drivers with information about
the structure of the car park system and the spaces available for them to park their cars.
The availability of the vacant parking spaces is calculated by means of sensors installed in
the parking areas, which count the number of cars that enter and exit from the parking
space. Also, the number of parking tickets issued at the ticket counter can be used to
calculate the vacant spaces. All this information from the sensors and the ticket counters
is used to update a central database which stores all the information about the areas of the
parking space which is vacant or occupied. Smith and Roth(2003) also compare the
parking techniques used at various airports in the United States. Among these, the
notable ones are Houston International airport and the Baltimore airport at
Massachusetts. The parking spaces at Houston international airport have wires embedded
at the entry. exits and the various levels of the parking lots. These wires act as sensors
and record the entry and exit of the card to update the central database. At the Baltimore
airport, there are ultrasonic sensors at the top of each parking space which sense the
availability or unavailability of each space. These sensors update the central
database. Information from this central database is used to display information at
the"way-find" signs at the end of each row of the parking area and advise the drivers
whether parking space is available or unavailable in that particular row These advanced
car park systems also provide advanced, electronic payment options for the
customers. The idea behind these electronic payment options is to
prevent the customers from having to wait in long queues to but a ticket. "Queues can
cause congestion in areas within and outside ofparking facilities[1]. Smith and
Roth(2003). in their article, cite examples of mobile parking or"m- parking" facilities
that are being used in Vienna(Austria) and Melbourne(Australia). Under the m-parking
technology, customers initially register their mobile number, the license plate number of
the car and their credit card number with the car park authorities, to create what is called
a"virtual parking ticket account 12l. This completes the initial, one-time registration
process. Whenever the customer needs to park, they would send an SMS text message to

28. the number provided by the car park authorities. The SMS message would consist of the
license plate number of the car, the location code of the parking area where they want to
park and the time duration(in minutes) for which the customer wants to park. In
return, the customer would then receive a text message from the car park message
centre, with the confinmation and the expiry time of their electronic parking ticket. The
customer would be sent a reminder SMS, 10 minutes before the parking time
expires. The bill for the parking ticket would come up on the customer's mobile bill
Thus, these advanced car park techniques provide the car parking authorities as well as
the customers with the following advantages(Smith and Roth, 2003) Reduction in time
spent and fuel consumed while searching for available parking space. in congestion due
to fewer cars driving around searching for Reduction Elimination of queues entering
parking facilities because drivers will not go to a facility where there is no available
space. Reduction in illegally parked vehicles. vy Rene distribution of flow and parking
demand through the area
