  2. 2. PRESENTATION ON PREPAID ENERGY METER USING GSM By P.Uday kumar reddy M.Swetha P.Renuka P.Santosh (10141A0281) (10141A0280) (10141A0255) (10141A0261) UNDER THE ESTEEMED GUIDANCE OF Mr.JOHN WESLEY M.tech Asst.professor
  3. 3. ABSTRACT 1 Provide the adequate supply to customers and collect the fare effectively. 2 The imperfection in traditional billing systems. 3 To overcome this imperfections this project is designed. 4 The application is mainly based on microcontroller.
  4. 4. INTRODUCTION 1.Automatic meter reading (AMR) system. 2. Growth of metering instrument technology. 3. Prepayment metering
  5. 5. BLOCK DIAGRAM 1-PH 230V 230/9 T/F AC TO DC CONVE RTER 5V 16X2 LCD DISPLAY MICRO CONTROLLER (AT89S52) RELAY GSM ENERGY METER LOAD
  6. 6. MICROCONTROLLER •In this system AT89S52 microcontroller is used. •256 bytes of internal memory. •4.0v to 5.5v operating range. •32 programmable I/O lines. •AT89S52 is a lowpower, high performance 8-bit microcontroller.
  7. 7. • . Controller receives the commands from GSM modem and activates relays as per the command. • And send the feedback SMS to operator through GSM modem. • Controller connects the load to the main supply by operating relays contacts.
  8. 8. Liquid Cristal Display •Interface with either 4-bit or 8-bit microprocessor. •16x2 display •Which displays the amount of power consumed
  9. 9. GSM • GSM means Global system for Mobile communication. • GSM transfer the instruction to main circuit from operator and vice versa. • The frequency range specified for GSM is 1,850 to 1,990 MHz
  10. 10. RELAYS • Relay is an electrical switch that opens and closes under the control of another electrical circuit. • The phase of main supply is connected to relays. • OFF condition relay contacts are in open, under ON condition contacts are in closed position. • Means it connects the phase to the load in ON state only .
  11. 11. •Input supply required to operate relay is 8-12v . •The output phase connected to relay range is 7 amp 250v. •It gives the sound while contacts are closing and opening.
  12. 12. AUXILARY COMPONENTS • Led lights are used to know the circuit status ,means power in the circuit is present or not. • Reset switch is used for restart the controller tasks from the beginning when ever it is struck. • Crystal oscillator is used to generate the proper voltage to relays in controller.(means generating clock pulses).
  13. 13. ADVANTAGES • High accuracy over a wide current dynamic range. • Tamper proofing. • Reduce financial risks. • Better customer service. • Improve operational efficiencies.
  14. 14. FUTURE SCOPE • A mini printer can be interfaced to get a printed bill or details of billing. • Remote recharging can be implemented through telephone line or wireless network. • Software can be modified to view the balance on request.
  15. 15. CONCLUSION This project is performing satisfactory function in laboratory condition. The device designed is used in conjunction with an Induction Energy meter. With minor modification in the software and hardware this system can be used for field application.
