EB Load Monitoring Through Telephone
Abstract
EB Load Monitoring Through Telephone project is developed
for the users to monitor a system load through Telephone. There are two units. One in the office and the other in the
user area. In the Office, a microcontroller kit is connected with a DTMF
encoder. A LCD display is connected with the microcontroller kit.
In the user area, a microcontroller kit is connected with a
telephone line. According to the usage of the electric power, the
microcontroller sends signal to the driver section and thereby operates a
telephone. Also the microcontroller operates corresponding relays to send the
meter reading through the telephone line.
In the other side, the telephone line receives the signal
through a DTMF encoder, the signal is converted to digital signal and given to
the microcontroller. According to the signal, the microcontroller sends signal
to a LCD display to display the meter reading in the user area.
Thus the individual consumer load is sensed and are
currently monitored in the office. It uses PIC16F73 (28 pin Micro controller). The micro
controller program is written in assembly language
