This document describes an automatic meter reading system using power line communication. The system has two main sections - the consumer section and the utility section which communicate via the existing power lines. At the consumer section, a microcontroller monitors and controls power usage to prevent exceeding predetermined limits. It can also cut power to certain devices. The utility section can remotely read consumers' energy meters by sending unique addresses through the power lines. Meter readings and billing details are then displayed for the consumer. The system provides automatic and accurate electricity billing without additional infrastructure for data transmission.

purposes. This technology is preferred over other
communication technologies like Satellite, Wireless and
Optical fiber communications due to wide availabilities of
power lines as Power lines are one of the most widely
available communication medium for PLC technology and
also it is already existing infrastructure.[1]

distances and with big amount of power in play. In this last
case AC power line systems are able to offer several services
such as reading the electricity meter, transmitting data and
voice over the standard lines, paying the electricity bill,
storing information about the network (peaks of power
absorption, revealing tampering attempt),solvingthe“local-
loop” problem.[4]

1.4 Proposed Experimental Work
Fig- 2 Block diagram of automatic meter reading using
power line communication.
Fig-2 shows to the Automatic meter reading using Power
line communication. And also consumerand utilitysectionis
shown in figure given above. This system has two main
sections, consumer and utility section, which are
intercommunicated using Power Line.
1) Load Management System The effectivemanagement of
the loads at the consumer side is an one of the main aim of
this system. A Microcontroller(LPC2148)isprovidedat each
consumer side which controls the load. In this system the
peak time is decided by total load connected to the utility
and is not fixed. Hence a predetermined peak value is
initially set in the microcontroller and if the power
consumption exceeds the predetermined value, the
microcontroller initially warns the consumer through the
LCD module. If no action is performed by the consumer, the
controller cuts of the supply to certain devices in a
prioritized manner.
2) Energy meter system -This system is kept in
synchronizing with the utility. Each and every consumer is
provided with a unique address which is stored in the
Microcontroller as well as the utility data bank. When the
meter reading of a particular consumer is to be done, the
Utility sends the required address through the power line.
The required consumer microcontroller is uniquely
identified and the microcontroller is instructed to read the
Meter. The meter reading is taking with the help of the
blinking pulses and the reading is returned to the utility. At
the utility, the required calculations are done and the bill
details are retransmitted and the microcontroller displays
this in the LCD module. The information is also saved in the
data bank for future use.
3) PLC modem- It is the ‘modem’ system of the setup. It
modulates and demodulates the data that is to be sent
through the power line. FSK modulation technique is
followed by the unit. It is placed at the consumer as well as
utility side for transmission and reception and vice versa.
Serial communication method is used for the power line
transfer.
1.5 METHODOLOGY
The system setup is divided into 2 sections, namely the
Consumer section and the Data Monitoring section.
A) The consumer section of the automatic electricity billing
system has-
1) An energy measuring unit consisting of a digital energy
meter and a light dependent resister.
2) Relay is an used to the working of the switching unit.
3) A control unit used to control the processes taking place.
4) An LPC2148 microcontroller is used.
5) An LCD module is used.](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
