Abstract:
At present, most of the houses in India have the traditional mechanical watt hour meters and the billing system is not automated . At the end of each month a person from the electricity board goes to every house and takes the meter reading manually. These meter readings are used for electricity bill calculation and this bill sent to consumer house by post. Customer goes to electricity department for paying this bill amount. But in this technique we are required great number of persons for reading the meters. The procedures of sending the bills to customer are very laborious and cumbersome. But a new technology is named Automatic Meter Reading System is discuses. Apart from being a boom, AMR wipes out all the cons of conventional systems. Automatic Meter Reading System is a sophisticated system which allows companies to collect the reading without visiting the site.AMR include various technology for data collection such as power line communication, Zig-bee, Radio Frequency (RF Method) and GSM network but GSM network is best among this technology. So this paper will discuss only GSM based AMR system. Automatic meter reading system helps the customer and energy service provider to access the accurate and updated data from the energy meter.AMR System can send energy consumption in hourly, monthly or on request. This data is sent to central system for billing and troubleshooting .These data are stored into the database server for processing and recording. This technology mitigates labour cost, collection time, energy theft, avoids
late payment. Adding to this it increases data security, improved customer service,reduced revenue losses. This system is not only sending the data but also it does provide power disconnect/connect feature,power cut feature and tempering alert feature .All these advantages give this product an edge over other pragmatically prevailing devices.
II. Comparison between Automatic Meter Reading System and Conventional Metering System:
Table 1. Succinctly spouts out comparison between Automatic Meter Reading System and Conventional Metering System. Using AMR Technology we can control and monitor any energy meter located anywhere in the world.GSM based energy meter or AMR are provide tempering alert, auto disconnect feature, power cut facility. Automatic meter reading system is access to real time data and received customer complaints. So costs for meter reading will be reduced. AMR system avoids meter reading error and reading data automatically. Its also provides increased security of data
SYSTEM OVERVIEW OF AUTOMATIC METER READING SYSTEM:
Figure-1 shows a System overview of AMR.AMR Continuously monitor and record the energy meter. This can be achieved by using microcontroller unit. Microcontroller unit are interfaced with digital energy meter. Microcontroller unit are interfaced with the RTC by using 2 wire serial interfaces for date and time and RTC memory are also used as data storage permanently. Microcontroller unit are also interfaced GSM modem for remote monitoring and control domestic energy meter. The data received through GSM Modem and network. Data is being sent to the AMR on request and within a particular interval. Once the meter received the request of data from the energy provider, SMS gateway will immediately reply the meter reading with that date and time. The data received from meter is stored in database server through SMS gate way for processing and record. This data received from meter are stored in database server according to Meter ID that is providing to customer house. At the end of each month the server using the detail of database server and calculate the bill amount and send the complete detail of consummation of unit, and total bill amount. User can verify the same AMR possess have transparency on the part of customer and service provider.
