Automatic Meter Reading

CHAPTER NO. 1

The basic purpose of metering is to measure how much the consumers utilize power and it tells the total demand of the power required to run the complete electric system of the country. We measure the increasing demands on the power system by energy meters and install new generating station according to the energy requirements.
First, the most common type of electricity meter is the electromechanical induction watt-hour meter. The electromechanical induction meter operates by counting the revolutions of an aluminum disc, which is made to rotate at a speed proportional to the power. The number of revolutions is thus proportional to the energy usage. It consumes a small amount of power, typically around 2 watts.
Electronic meters display the energy used on an LCD or LED display. In addition to measuring energy used, electronic meters can also record other parameters of the load and supply such as maximum demand, power factor and reactive power used.
This thesis demonstrates the use of the GSM based energy metering and billing system. How it will improve the billing system in city and remote areas of our country.
1.1   Statement of the Problem:
Automatic meter reading (AMR) is the technology of automatically collecting data from energy metering devices and transferring that data to a central database for billing and/or analyzing. This saves employee trips, and means that billing can be based on actual consumption rather than on an estimate based on previous consumption, giving customers better control of their use of electric energy.
This means that billing can be based on actual consumption rather than on an estimate based on previous consumption, giving customers better control of their use of electric energy. The Transmitter is connected to the meter and it counts the pulses from it and displays it over the seven-segment display. It transmits the data over radio frequency. At the receiver end the data is received by an receiver module and...
