DESIGN & IMPLEMENTATION OF A

PRE-PAID ENERGY METER

 

By : Projectsworld Team


INTRODUCTION

OBJECTIVES:-

 

  • To Design a circuit of an electronic power saving pre-paid energy meter.
  •  Develop new ideas to implement this circuit purposely.
  • To study the circuitry and different types of components &  opto-coupler, 89c51 microcontroller, relay, IR-LED, photodiode and programming in assembly language .

 

A scheme of Electricity billing system called a PREPAID ENERGY METER WITH TARIFF INDICATOR can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings.

Every consumer can buy a memory card. The memory card is available at various ranges (ie. Rs 25, Rs 50, Rs 150 etc).In our project we have given the name for memory card as smart card.
When the consumer insert a smart card into the card reader which is connected in prepaid energy meter with tariff indicator kit. Then the card reader will read the stored information using the MC program. So that the smart card cannot be reused by others. Suppose if a consumer buy a card for Rs.25/- he / she can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.

NEED TO SAVE THE ENERGY:

  1. The saving of energy will help our country to develop economically and socially.
  2. The energy which is wasted can be utilized somewhere in the remote area.
  3. It is also very helpful in our life to reduce the electricity bill.

HOW CAN WE HELP IN SAVING THE ENERGY?

We can save energy by using the electrical appliances only when needed. So the appliances should be switched off when you are not using them. Generally what happens:-

  1. We are not in the room and the appliances like bulb, tube lights, fans are switched ON mode.
  2. The AC, fans are ON when the temperature is quit low. This carelessness/ignorance not only wastes the energy but also have bad effect on your health.
  3. All the lights/bulbs are ON and only when the visibility light required.
  4. Leave the computers ON while we are not working on it means when we are reading book in front of it, gossiping, going for the lunch etc.
  5. Generally in our home some program is running and nobody is there to enjoy it.
