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The traditional archaic pumps have now been replaced by more advanced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.

Mobile phone:

Interfaces to the UART of the controlled and used to send SMS message

to the user by using GSM technology.

In this project the customer having the prepaid card. The card is nothing

magnetic member is embedded in the card.

Relay Driver and Relays: Relay drivers are used to drive the electromagnetic relay .

Relays acts as a electromagnetic switch for the Pump and motors.

This also used in

Logic functions.

Time delay functions.

12

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.

13

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.

14

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.

15

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.

Working of Level sensor

16

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.
