Embedded Based Multi Channel Data Transceiver
Abstract
Data transmission and reception in different frequency
requires process like modulation, tuning etc. In this project, we use a
different technique to transmit and receive data without doing any phase or
frequency modulation.
The main module in this project is Antenna(Core of sliding
plates) which determines the frequency of transmitting and receiving data. The
angle of the core plates can be adjusted using a motor. The direction of the
antenna can be horizontally adjusted using a geared motor. The angular
direction of the antenna is also adjusted using a geared motor. These motors
are controlled by the microcontroller.
The user can set the frequency through the key pad. The
settings are displayed in the LCD display. Accordingly the microcontroller
sends signal to the direction control motors through driver unit. Accordingly
the direction control motors turn the antenna.
The data to be transmitted is given to the antenna. This
data is transmitted in the particular frequency. Similarly the data can be
received by setting the antenna in a particular direction. The microcontroller used in this project is PIC 16F877A. The
microcontroller program is written in assembly language.
