BUS DETECTION DEVICE FOR THE BLIND USING
PASSIVE RFID APPLICATION
(ABSTRACT)
RFID is a wireless personal area networking
standard which provides features like non line of sight
detection of tag by RFID reader from a distance of up
to 1.5 meter. This feature help in using RFID in many
applications.
This projects demonstrates the concept of bus detection
system by the blind people using RFID. In which the blind
people having RFID reader with some microcontroller module
which gives the buzzer sound whenever the specifc bus
comes, the bus is equipped with RFID tag. Whenever bus
comes at bus stop the blind person who is provided with RFID
reader get signal as it reads tag.

In our proposed project we are using LPC2148 (ARM7)
based microcontroller, which the current dominant
microcontroller in mobile based products. RFID reader is
connected to microcontroller based embedded board and a
program is running which will analyze tag data on the bus and
send signal to the buzzer if the bus tag data matches with
program data. We are using software development Tool as Keil,
fash magic for loading hex fle in to the microcontroller
SOFTWARE: Embedded ‘C’.
TOOLS: Keil,Flash magic.
TARGET DEVICE: LPC2148(ARM7) MicroController.
APPLICATIONS: Blind people bus indication also can
be usefull for illiterate people.
ADVANTAGES: Easy and low cost method.
REFERENCE: The 8051 micro controller and
embedded systems by Mazidi and LPC datasheets,
and the user manual for the LPC2148.
