3. INTRODUCTION GURUKULINSTITUTEOFTECHNOLOGY PRESENTED BY
NAGENDRANATH BISWAL REGD NO-1221315049 In 1886 , the first ac
transmission line was installed . Hence , the first generation of
power meters was found which we know as (Watt-Hour meter ). As most
of us know , the first generation(traditional meter reading devices
) is being used tell now in many places . To overcome this
disadvantages we have to modify a new reading system that provides
remote reading , safety , on-time readings and a simple user
interface . That is what AMR provides successfully . Power
consumption reading and analysis using AMR has a lot of benefits
which we will discuss in this papers . This benefits make it clear
that this system will be used in most of the regions of the world
in the next few years .
4. What is AMR? GURUKULINSTITUTEOFTECHNOLOGY PRESENTED BY
NAGENDRANATH BISWAL REGD NO-1221315049 AMR brings significant
benefits to the customer by providing increased meter-reading
accuracy, fewer estimated bills, rapid response to read requests,
automatic leak detection and billing options and provides detailed
usage information about individual sites, which allows the company
to offer variable rates and encourage price -responsive behavior
among customers. AMR improves operational management by providing
just-in-time meter replacement, tamper detection, remote access,
and automatic scheduling of meter reading. In short, AMR will
optimize cost savings and maximize efficiency while providing
improved customer service.
5. Traditional meter reading system
GURUKULINSTITUTEOFTECHNOLOGY PRESENTED BY NAGENDRANATH BISWAL REGD
NO-1221315049 Highly Person dependant. Human errors cannot be
avoided. Accessibility of meters in rural/ Agricultural zones.
Energy Audits performed based on bill collection which is highly
inaccurate. Billing done mainly on estimated/ monthly average basis
Inability to monitor and control discrete loads Billing cycle
requires excessive time. Meter data used only for billing, cannot
help in analysis like demand analysis, energy audit, pinpointing
losses, etc.

8. GURUKULINSTITUTEOFTECHNOLOGY PRESENTED BY NAGENDRANATH
BISWAL REGD NO-1221315049 Consumer Side Unit (CSU) Transmitter unit
is used to send the meter reading to the receiving end. The data is
send to the receiver end through RF channel. The transmitter unit
consist of transmitter module, encoder HT12E, microcontroller
AT89C2051 and display driver 74LS244.The pulses are given to the of
microcontroller via optocoupler. For display the meter reading we
are using seven segments. The supply which is given to the
transmitter unit is +5 volt. The meter data is stored on the EEPRO
memory unit .

BISWAL REGD NO-1221315049 Server Side Unit (SSU) At the receiving
side , a RF receiver collect the data transmitted from the consumer
side , decode it , and transfer the decoded data to the server
computer which analysis this data and insert it into the
database

PRESENTED BY NAGENDRANATH BISWAL REGD NO-1221315049 Consumer side
unit (CSU) operation: The microcontroller receives the measured
quantity as analog data from the energy meter port which is , in
watt-hour meters , a potential and current quantities . The
microcontroller is programmed to analysis this quantities then it
display the reading in the LCD screen . When the server wants to
collect the reading from the meter , it sends a message to the
meter which receive it throw the antenna and the GSM modem
connected with it . This message call the meter to wake up and then
it makes a data frame consisting of the meters information and
sends it to the server which collect them and store them in the
database . The data collection can be done at any time or
periodically such as hourly, daily, weekly or monthly.

PRESENTED BY NAGENDRANATH BISWAL REGD NO-1221315049 Server side
unit (SSU) operation: First , the SSU send a waking message to the
CSU to tell it to wake up and start preparing data . After the CSU
response and send the data , the SSU collect this data , analysis
it and make the computations needed , then it store them on the
database of the company . The SSU can reprogram the CSU and fully
control it by sending connect/disconnect commands or applying
remote energy management . This reprogramming and controlling
processes is being done throw commands transferred throw the
communication channel between the SSU and the CSU .
