GSM Based Weather Station Reporting System
Nowadays, electrical accidents to the line man are increasing, while
repairing the electrical lines due to miscommunication
between the maintenance staff & the electric substation staff. During the electrical fault or short circuit, the power
network will suffer from a high stress of fault current in them which may harm
the equipment permanently.
To
overcome this problem, we introduces password based load control system which is arranged in such a way that maintenance staff
or line man has to enter the password to ON/OFF the electrical line. Separate passwords are allocated for every electrical line that
access by authorized person only. Now, if there is
any mistake in the electrical line then the line man will switch off the power supply to the line by
entering password and comfortably repair the electrical line.
Block
diagram:
The
main component in the circuit is 8051 microcontroller. A 4×4 matrix keypad is
used to enter the password. The password which is entered is compared with the
predefined password stored in ROM of microcontroller. If entered password is
correct, then the corresponding electrical line is turned ON or OFF and
display line or load status on LCD. If the password is wrong, then display
“wrong password” on the LCD.
In this project a separate password is provided to each electrical line.
Activation and deactivation of the line (circuit breaker) is indicated by the
load (Light Bulbs).
