PROJECT DESCRIPTION

The project is designed for access control with the help of a password only. A keypad is connected to the project to enter the password. For example fatal electrical accidents to the line man are increasing day by day during the electric line repair due to lack of communication and co-ordination between the maintenance staff and the electric substation staff.

This proposed system provides a solution, which can ensure the safety of the maintenance staff, e.g., line man. The control to turn on/off the line lies with the line man only. This system has an arrangement such that a password is required to operate the circuit breaker (ON/OFF). A line man can turn off the supply and comfortably repair it, and on return to the substation, he can turn on the line by entering the correct password.

The system is fully controlled by a microcontroller from the 8051 family. A matrix keypad is interfaced to the microcontroller to enter the password. The entered password is compared with the password stored in the EEPROM interfaced to the microcontroller of the 8051 family. If the password entered is correct, then only the line can be turned on/off. Activation / deactivation of the circuit breaker are indicated by a lamp (on/off) provided in the project..

Furthermore, the project can be enhanced by integrating a GSM module such that the password can be sent over a GSM network for the user to change/enter the password for a more secured system to remotely control the circuit breaker via SMS.
