PREPAID CARDS FOR PETROL BUNKS


2/42

SECTION 1: PROJECT TYPE

Micro controller (AT89C51) hardware design with software development (Device

Driver).

SECTION 2: PROJECT DESCRIPTION

A scheme ofPrepaid Card for Petrol Bunk System can facilitate in improved

cash flow management in fuel utilities and can reduce problem associated with

deployment of manpower for collecting bills. Every consumer can buy a memory card (is

nothing but an EEPROM IC) with a password stored inside it using a MC program. The

memory card is available at various ranges (i.e. Rs 50, Rs 100, Rs 200 etc).In our

project we have given the name for memory card as smart card. When the consumer

insert a smart card into the card reader which is connected to tariff indicator. Then the

card reader will read the stored information and delete the information from the

EEPROM IC using the MC program. So that the smart card cannot be reused by others.

Suppose if a consumer buy a card for Rs.50/- he / she can insert this amount through the

card reader so that tariff indicator kit will be activated. According to the fuel consumption

the amount will be reduced. When the amount is over, the relays will automatically

shutdown the whole system. In our project we also have a provision to give an alarm

sound to consumer before the whole amount is reduced.

The complete project is built around the 8051 micro controller. PCB Wizard

Schematic generation software is employed to prepare the schematic for development of

project. Hardware is built according to schematic prepared by soldering each componenton the general purpose PCB. Source code is developed using KEIL micro vision software.

Vision is an IDE (Integrated Development Environment) that helps you write, compile,

and debug embedded programs. The written source code is dumped into the


3/43

microcontroller IC using a Programmer. To dump the code into microcontroller micro C

Flash software is used.
