3. 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. 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. 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. 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 .
9. 9. GURUKULINSTITUTEOFTECHNOLOGY PRESENTED BY NAGENDRANATH 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

AMR theory of operation GURUKULINSTITUTEOFTECHNOLOGY 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.
13. 13. AMR theory of operation GURUKULINSTITUTEOFTECHNOLOGY 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 .
