Abstract:
The project “Wireless Notice board Display” is based
upon wireless transmitting of data on a simple LCD. Basically in colleges there
are notice boards which are still operated manually. Each time they have to
display a new notice, they will go and stick the piece of paper on which the
notice is written. In our project, there will be an LCD in place of notice
board and operating software in place from where it has to be operated. The
user simply has to type the message in the textbox given in the GUI and simply
click on the send button. The GUI is programmed in such a way that it sends one
by one character at a time to the notice board through Transreceiver. The whole
system of notice board is such that it will eventually receive the character
and start displaying it on the LCD screen. The kind of Transreceiver this
project uses is of high range. So it can directly work on the departmental
level. More modifications can be done in future, such as increasing size of
LCD, increasing the range of Transreceivers etc. But for now it can be easily fixed
into class rooms and students can check this instant notice board for any
updates from authorities.
Introduction:
One of the main reason behind making this project
was, When we saw the procedure of displaying the normal notice on our departmental
notice board, we thought of digitalizing the whole process. The basic necessity
of this project is that, during normal procedure of notice, it may get delayed
due to substantial methods. But when we digitalize the process, the respected
higher authorities could directly send the message from their computer without
even moving from chair. Which will surely overcome this delay, and also there
is no wastage of paper for each notice, which eventually is environment
friendly.
This system is efficient and can be used in many
places including government offices, schools, Colleges, factories and many more
industrial, commercial and medical places.
Problem
Formulation:
The basic general Idea of the project was to send a
simple message or notice from the computer. The person or the user will have software
installed on his/her Computer made especially for operating notice board. The
user has to simply type the notice in the GUI and click on the send button. And
the GUI will then send the data on the notice board for displaying. The notice
then will be finally displayed on the LCD screen attached. The problem with the
earlier system was that it used hard copies of notice which proved worth after
its use. And also displaying and changing the notices on the regular basis. The
whole Development of the project will be distributed in three parts:
1. Transmitting
section: In this phase a GUI for operating the software has to be made
attached with the transmitting hardware.
2. Receiving
section: In this phase, An LCD will be attached to a small system which
will receive data from transmitting section and display one by one on the
screen at a time.
3. Integrating
section: In this phase, we will synchronize the transmitting section
and receiving section respectively.
Ojective
and Scope of the project:
1. To digitalize the present system of notice
boards.
2. To make a convenient and easy to use system with
increased efficiency.
3. To make a eco friendly system.
4. To prevent the disadvantages present in the
current system such as delay in notices etc.
5. To make a centralized operator for all the notice
boards.
6. Enhancement of the department in the technical
means.
Methodology:
1. Transmitting
section:
In our project,
there will be an LCD in place of notice board and operating software in place
from where it has to be operated. The user simply has to type the message in
the textbox given in the GUI and simply click on the send button. The GUI is
programmed in such a way that it sends one by one character at a time to the
notice board through Tran receiver
2.
Receiving Section:
The whole system of notice board is such
that it will eventually receive the character and start displaying it on the
LCD screen.
Hardware
and Software Used:
Hardware
Used:
1. Microcontroller(8051
family based P89V51RD2):
A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core,
memory, and programmable input/output peripherals. Program memory in the
form of NOR flash or OTP ROM is also often included on chip, as
well as a typically small amount of RAM.
Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose
applications.
2. CC2500
Tran receiver:
The CC2500 radios are transceivers
designed for very low-power wireless applications. The CC1100/CC1101 radios can
operate at frequency bands 315, 433, 868, and 915 MHz. The CC2500 radio
operates at 2.4 GHz.
3. 16x2
LCD:
A 16x2 liquid crystal display (LCD) is a thin, flat
electronic visual display that uses the light modulating properties of liquid
crystals (LCs) Which can display up to 32 Characters at a time.
Software
Used:
1. Matlab:
Matlab or Matrix Labortory is a software which is widely used for image
processing and GUI development. We are using Matlab for the GUI purpose and
also because it provides a very convenient method for serial communication.
2. Keil
Cross Compiler: Keil Cross Compiler is a compiler that is mainly used
for converting Embedded C language into Assembly language program.
3. Flash
Magic: Flash Magic is a software that will be used to program the
microcontroller.
Conclusion:
Now a days it is really important for digitizing
all possible means. Since we are living in 21st century an era where
there is technological boom all over the world. Its has widely grown in many
sectors including education sectors also. So Education sector must not be
untouched through this. Through our project we are taking a small step towards digitalization
of the class rooms and preventing the old and hectic methods of education. It
will be fast, effective and user friendly. This project is also playing a role
in saving environment by saving the papers used for notice board along with its
modernization.
