Automated have added to the new look of the petrol bunks. A drastic change which has taken the city by storm is the petrol machines that have invoked a new look with automated systems invading this area also. Now one can get updated details on the mobile using the cutting edge GSM Technology. This makes the customers know the exact quantity of petrol that has to be filled in, getting over the perennial problem of forgoing small change which most of the times the attendants at the bunks pocket for themselves. The traditional archaic pumps have now been replaced by more advanced EMP Petrol Pumps for proper filling of fuel. This not only ensures accuracy, but also saves a lot of time for customers and avoids misconceptions and arguments. To demonstrate this as a project we have developed a PIC Micro controller based Petrol bunk automation system.

Abstract:
 Automated have added to the new look of the petrol bunks.
 Now one can get updated details on the mobile using the cutting edge GSM
Technology. This makes the customers know the exact quantity of petrol that
has to be filled.
 The traditional archaic pumps have now been replaced by more advanced
EMP Petrol Pumps for proper filling of fuel. This not only ensures accuracy, but
also saves a lot of time for customers and avoids misconceptions and
arguments.
 To demonstrate this as a project we have developed a PIC Micro controller
based Petrol bunk automation system.

Objective:
The objective of this project is to provide easy access and save time
in the petrol bunk

Project working:
 Each vehicle is fitted with a prepaid card. When a car has arrived at the
gate, the RFID reader reads the card and opens the gate, only when the card
is a valid card.
Once entered the user will be shown the balance amount available on the
card and he must select a option to dispense the fuel based on liters or
rupees.
The system should check whether the user has entered a valid data i.e.,
the amount should not exceed the balance available in the card.
After ensuring that, a motor is actuated to dispense the fuel. Once this is
done, the information such as available balance is sent to the user’s mobile
phone using GSM technology.

LCD Display:
Used to display the events
16x2 character LCD display
Advantages:
Very compact and light.
Low power consumption so
little heat emitted.
No geometric distortion.
Can be made in almost any size or shape.
No theoretical resolution limit.

Power Supply unit :
Generates DC Power supply for the total unit from the 230V AC supply
Key pad:
Keypad is used to set the amount of fuel to the filled in.

Alarm :
Alarm is actuated when there is a wrong card or when no balance
is available
Smoke sensor:
The Infra-Red LED is a lens that
shots a beam over a large area.
If smoke is present in the room, it
enters the optical chamber, having
smoke particles scatter and sensor
sets of the alarm.
if any smoke gets inside the
chamber and absorbs the alpha
particles,
it lowers the level of ionization,
hurting the flow of electrodes, thus
setting off the alarm.
Used to detect any smoke in the area.

Infra red Level sensors:
Used to sense the fuel level available in the tank . A sensor is able to
detect a change and communicate that change with a user.

Engine Switch:
Used to switch off engine when found on.
Software:
1. MPLAB® X IDE
MPLAB® X IDE is a software program that runs on a PC
(Windows®, Mac OS®, Linux®) to develop applications for Microchip
microcontrollers and digital signal controllers. It is called an Integrated
Development Environment (IDE), because it provides a single integrated“
environment” to develop code for embedded microcontrollers.

Conclusion:
By installing this project is made the automated petrol
bunk. The customer need not wait in the petrol bunk. It reduces the
time as well as man power.
