Password based circuit breaker control to ensure electric

  1. 1. PASSWORD BASED CIRCUIT BREAKER CONTROL TO ENSURE ELECTRIC LINE MAN’S SAFETY
  2. 2. ABSTRACT  The project is designed to control a circuit breaker with help of a password .  This proposed system provides a solution, which can ensure the safety of the maintenance staff.  EXAMPLE: Line man  The control to turn ON/OFF the line lies with the line man only
  3. 3.  This system has an arrangement such that a password is required to operate the circuit breaker (ON/OFF).  Line man can turn off the supply and comfortably repair it, and return to the substation, then turn on the line by entering the correct password.  The system is fully controlled by a PIC16F877A IC.  If the password entered is correct, then only the line can be turned ON/OFF. Activation / deactivation of the circuit breaker is indicated by a lamp (ON/OFF).

  6. 6. DESCRIPTION OF COMPONENTS: PIC16F877A  PIC16F877A is the flash technology, so that data is retained even when the power is switched off.  Easy programming and Erasing are other features of PIC 16F877A.  The A/D convertor module in PIC 16877A has eight inputs .The conversion of analog input results in a corresponding 10 bit digital output. The A/D module has four registers.
  7. 7. LCD Display (16x2)  LCD (Liquid Crystal Display) screen is an electronic display module.  A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits  A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data.
  8. 8. CONCLUSION  Thus the mini project ,’’PASSWORD BASED CIRCUIT BREAKER CONTROL TO ENSURE ELECTRIC LINE MAN’S SAFETY THE PIC MICROCONTROLLER’’.  This proposed system provides a solution, which can ensure the safety of the maintenance.  The control to turn ON/OFF the line with the line man only...
