Hardware Setup



A power
supply is an electronic device that feed electric energy to the electrical
device. The main function of a power supply is to switch one form of electrical
energy to another and, as a result this is used to supply power to the ration
distribution kit.



The RFID uses wireless technology to
identify the object. It consists of RFID tag and the reader. The bidirectional
communication between the tag and the reader is accomplished by the radio
frequency (RF) part of the electromagnetic spectrum to carry the information
between an RFID tag and reader. Passive RFID tags are used in this system as an
e-ration card. It does not require any external power supply. The tag antenna
receives the RF signal (13.56MHz) from the reader. This received signal is
rectified and supplied to the chip to power it up. Now tag retransmits the
signal to reader. The reader receives it. Then the signal is sent for further
computation of the data.


3.       GSM

The GSM (Global System for Mobile
communication) module consists of GSM modem. It is a standard developed by the
European telecommunication standard institute to describe protocols for 2G
digital cellular networks used by mobile phones. It accepts SIM cards, and
operates over a subscription to a mobile operator, just like mobile phones. It
uses frequencies between 890-915 MHz UL and 935-960 DL (Band of 25MHz). Through
this GSM modem, SMS is delivered automatically to the subscriber about
availability of food grains at the ration distribution centre and about the



The RS-232 is a
communication cable, commonly used for transferring and receiving the serial
data between two devices. It supports both synchronous and asynchronous
data transmissions. Many devices in the industrial environment are still using
RS-232 communication cable. Rs-232 cable is used to identify the difference of
two signal levels between logic 1 and logic 0.

        The logic 1 is represented by the -12V
and logic 0 is represented the +12V. The RS-232 cable work at different baud
rate like 9600 bits/s, 2400bits/s, 4800bits/s etc. The RS-232 cable has two
terminal devices namely Data Terminal Equipment and Data communication
Equipment. Both device will sends and receives the signals. The data terminal
equipment is computer terminal and data communication Equipment is modems, or
controllers etc.


5.       LCD

Liquid Crystal Display is the technology
use to display the various information to the consumer. In this system LCD is
used to convey message with user. It shows the message and according to that
the customer responds to the system.


6.       Motor with Driver Circuit

The internal configuration of a DC motor
is designed to harness the magnetic interaction between a current-carrying
conductor and an external magnetic field to generate rotational motion. In the
proposed system we are using motor for the withdrawal of sugar or rice. The
motor driver circuit is used to provide proper matching between motor and



It consists of piezo crystals between two
conductors. When a potential is applied across these crystals, they push on one
conductor and pull on the other. This, push and pull action, results in a sound

If the RFID tag is invalid then AT89S52 will
send signal to the buzzer. Buzzer will receive the signal coming from AT89S52
and it will produce some noisy sound.


8.       Motor Driver Interface IC L293D

L293D is a dual H-bridge motor driver integrated circuit (IC).
Motor drivers act as current amplifiers since they take a low-current control
signal and provide a higher-current signal. This higher current signal is used
to drive the motors.

L293D contains two
inbuilt H-bridge driver circuits. In its common mode of operation, two DC
motors can be driven simultaneously, both in forward and reverse direction. The
motor operations of two motors can be controlled by input logic at pins 2 &
7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor.
Logic 01 and 10 will rotate it in clockwise and anticlockwise directions,

This is an excellent automated trailing
system for distribution of ration material, the ration Materials (wheat, rice, sugar,
pulses, oil, kerosene, etc) distributed through automatic mechanism without any
help of humans.  The system is successfully
implemented and tested using aadhar card and RFID technology, the government
authorities can monitor and control of ration material the distributing
material. The government money and public time is saved; poor people are
greatly benefited and the database can be maintained for long years easily
without any illegal activities. System is transparent and it control over
corruption and distribution of ration in open market. Dealer as well as fraud
customer will not be able to keep duplicate ration cards. It help to modernize
traditional rationing system and fight against corruption up to a great extent.
