PREPAID ENERGY METER USING SMARTCARD

By, MELBIN, SANDEEP & VASUDEV (S6 eee)Project guide : Miss. MINI KRPREPAID ENERGY METER USING SMARTCARDPREPAID ENERGY METER USING SMARTCARD To design and develop a prepaid energy meter where consumers buys energy in advance. It is implemented with the help of a smart card by recharging it for a specific amount.aIM22Electricity users can buy specific amount of energy to use it only when they needed. This is achieved by interfacing energy meter with smart card technology.

Smart cards have achieved a growing acceptance as a powerful tool for security, identification, and authorization.

People can buy specific amount of energy to use it only when they need.

To reduce the power bill defaulter using smart card technology.

Saves lot of time and power for electricity department.

User can recharge the card whenever the power is required.PREPAID ENERGY METER USING SMARTCARDabstract3The project consists of a microcontroller, energy meter, relay, buzzer, LCD, Keypad, LED indicators and smart card reader. The microcontrollers internal non-volatile memory is used to store the electricity consumed.The nonvolatile memory inside the Smartcard is used to store the prepaid amount. When the recharged units become zero on power consumption, the microcontroller put off all the loads connected to it by giving an audible beep sound. User has to recharge the same Smartcard for further usage of electricityPREPAID ENERGY METER USING SMARTCARDabstract4Displays the consumption of electricity along with balance amount through a front end display fitted into the meter.

Creates day to day awareness about daily usage.

Reduces problem associated with billing for consumer particularly living in isolated rural areas and slums.

Moreover this also reduces deployment of extra man power for taking meter reading, payment collection.

Avoids payment defaulters and further disconnection.Removes the entire infrastructure for electricity bill collection system.PREPAID ENERGY METER USING SMARTCARDSIGNIFICANCE OF PROJECT5162 LCDENERGY METERATMEL89S52BUZZERDRIVERRELAYLOADEEPROMSLOT FOR RECHARGEPREPAID ENERGY METER USING SMARTCARDBLOCK DIAGRAM6CIRCUIT DIAGRAM7

77The microcontroller will read the power consumed and update the balance unit available in EEPROM.

The system will produce a beeping sound when the balance is below a specified unit.

The power get automatically cut when the balance in the Smart card is nil or zero.PREPAID ENERGY METER USING SMARTCARDEXPECTED RESULT8Employed in large apartments and flats where residents can have improved cash flow management in energy utilization.

This system can be replaced with the GSM Modems, by which tracking of the consumers load on a timely basis is possible, which will help in tracking maximum demand, detect theft and more over instead of recharging the chip, the readily available recharge cards used in cell phones can be introduced. Using these other mechanisms, consumers can recharge their meters at their convenience and making the system much more user friendly PREPAID ENERGY METER USING SMARTCARDSCOPE OF THIS PROJECT9www.8051projects.net
