Password based control system for line man saftey

  1. 1. SIR VISHVESHWARAIAH INSTITUTE OF SCIENCE&TECHNOLOGY ANGALLU, MADANAPALLI-517325 DEPARTMENT OF ELECTRICAL & ELECTRONICS ENGINEERING A PROJECT ON PASSWORD BASED CONTROL SYSTEM PRESENTED BY A.SOWMYA 10W51A0202 K.BHAVANA 10W51A0224 M.RAMESH 10W51A0239 Y.NAGA JYOTHI 10W51A0257 V.MADHUSUDHAN NAIDU 11W55A0210 Under the Guidance of Sri T.MUNI PRAKASH, M.Tech, Assistant professor Department of Electrical & Electronics Engineering
  2. 2. CONTENTS  Main Objective  Kit Components Explanation  Block Diagram  Working Procedure  Advantages  Applications  Conclusion and Future scope  References
  3. 3. MAIN OBJECTIVE  The project is designed to trip the circuit with the help of a password.  This control system provides a solution , which can ensure the safety of line man.  The system is fully controlled by the 8052 microcontroller (where password is saved initially)and by an IC.
  4. 4. Hardware Requirements  Transformer  Bridge Rectifier  Voltage Regulator  Micro Controller  EEPROM  TRIAC  Keypad  LCD screen
  5. 5. TRANSFORMER STEP UP TRANSFORMER STEP DOWN TRANSFORMER
  6. 6. BRIDGE RECTIFIER
  7. 7. VOLTAGE REGULATOR  A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level.
  8. 8. MICROCONTROLLER
  9. 9. PIN DIAGRAM OF 8052
  10. 10. TRIAC  The TRIAC is a three terminal semiconductor device for controlling current.  It is effectively a development of the SCR or thyristor, but unlike the thyristor which is only able to conduct in one direction, the TRIAC is a bidirectional device.
  11. 11. KEYPAD  Keypads are the most widely used input devices of the 8052and a basic understanding of them is essential. The keypads are mainly three types: 1) 4*3 keypad 2) 4*4 keypad 3) 4*8 keypad.  The keypad used in this project is 4*3 keypad.
  12. 12. LCD DISPLAY  LCDs are the most widely used output devices of the 8052.  LCD stands for Liquid Crystal Display.  LCD is finding wide spread use replacing LEDs.  They are used for writing different messages on a miniature LCD.

  15. 15. ADVANTAGES  It avoids the electrical accidents.  Improves lineman safety.  Easy of operation.  Easy to maintain and repair.  APPLICATIONS  Can be used any where in the substation to trip the circuit.  Most useful to operate in the public areas.
  16. 16. CONCLUSION  Security is prime concern in our day-to-day life. Every one wants to be as much as secure as to be possible.  This system provides a new approach to secure the life of a lineman.  The circuit can be tripped without any fail and load can also be controlled when required.
  17. 17. FUTURE SCOPE  The project can be interfaced with the GSM modem for the remote control of circuit breaker via SMS. So the circuit breaker can, not only operate from the substation, but also from distance through wireless communication.  SCADA can also be implemented to know where the fault is occurred in the system directly and so a linemen can directly locate the fault location and can rectify it.
