Real time implementation of home energy management

Abstract

Automation is the key word in every industry. Automation is essential to obtain the desired response much faster than the conventional methodologies. It ensures efficiency and increase in production and reduces human errors. The optimal goal of this project is to obtain a bi directional data communication by using the existing power lines. Here the energy consumed by the user is continuously measured and updated. At the end of the billing period, it can be received by the electricity board office on request. A processor IC senses the energy consumed, produces a digital pulse accordingly and displays the amount of energy consumed. These pulses are suitably modulated by the MODEM and superimposed along with the same power line. These pulses are alone retrieved at the electricity board’s office by the other MODEM and stored in the PC database. The tariffs are calculated based upon the slabs fed in the PC and sent through the modem which is received by the other modem. The LCD provided displays the number of units consumed and the cost. In this project, along with the automatic meter reading two more important things are implemented, they are power on demand and prepaid system with recharging facility.
