RECOGNITION : FIRST PRIZE
The aim of this project is to demonstrate the incorporation of computer
method in railway traffic control to improve, safety, speed of handling
the traffic and reliability. Here we employ the microprocessor (Intel 8085)
to handle the signaling, track changing and gate operation and to monitoring
the traffic. The system starts with the tracking if the train is sensed
at the station side or starts with the gate operation (i.e. gate closing
and opening) along with the track changing if the train is sensed at the
gate side. Once the train arrival is sensed at a distance of about 3 kms
the microprocessor performs the gate operation along with the track changing,
the identification of the train is done at a distance of 3 kms accordingly
the particular operation is performed by the processor.Depending upon the
priority of the incoming train, the unengaged track is given for train halting.

RECOGNITION: APPRECIATION PRIZE
The main application of this project is that, whatever reading we are getting
at the consumer's energy meter the same reading we can get at the electricity
office. It means that now we are directly communicating with consumer's
energy meter and if there will be any overload then e can get information
in the office only, so that we can repair it in less time. Here we are using
two parts, which are transmitting by the transmitted by the transistor with
certain frequency, the same information will be taken by the receiver part,
with same frequency and it will display on display unit. The project is
nothing but a step in the field of power electronics to improve our power
distribution for the better and bright future.
It contains mainly two parts, which are,fuse blow indicator and the energy
meter reader, hence by the use of antennas we can get information about
energy meter not only in electricity office but anywhere that we want.
Since it is wireless communication and the receiver part is so small that
one can make it anywhere. For the consumer it applicable because it can
give details about any short circuit or over voltage in their house wherever
they are. For the Government it is suitable because it is giving full
details about the distribution of energy and over / under voltage. Further
improvement of this project is applicable in industry for the Safety purpose
also.

ADVERTIESMENT DISPLAY

RECOGNITION: APPRECIATION PRIZE
The aim of this project is to design a Moving Message Display System of
the type commonly seen in shop windows, airports, and other public buildings.
The display will be required to be able to scroll a message from right to
left, with at least eight characters on screen at any instant. Other display
features (such as flashing text) will not be needed, since it would be extremely
difficult to add these using ordinary logic ICs.
An EPROM is used to store the message to be displayed on the LED display.
Bits from the EPROM output correspond to the seven LED's in one column
of the display. A high output turns an LED on, the LED display being a
common cathode type. In order to scroll the message across the screen,
the cathodes (displqy columns) of the LED's are scanned by the Cathode
Multiples Block at a speed high enough so that the flickering cannot be
seen. As each column is selected, the corresponding data for the LED anodes
(display rows) is output from the EPROM and the main Address Counter is
incriminated. After a number of scans set by the Scan counter, the Base
Address Counter is incriminated and the new value loaded into the Main
Address Counter. This sequence gives the issusion of the message scrolling
across the display. The system has a single clock which is effectively
divided down by each block.
