OVERVIEW:
Automatic
meter reading, or AMR, is the technology of automatically collecting
consumption, diagnostic, and status data from energy metering devices
(electric) and transferring that data to a central database for billing,
troubleshooting, and analyzing. This technology mainly saves utility providers
the expense of periodic trips to each physical location to read a meter.
Another advantage is that billing can be based on near real-time consumption
rather than on estimates based on past or predicted consumption.
WORKING:
From the above block diagram,
To achieve the instrument of data copying and transmission and other functions GPRS module is used. GPRS is networks for remote communication. They can combine with each other, through the net work’s gateway to achieve a user meter copying to control and transfer in distance.
Automatic Meter Reading system should have the following functions:
- Timing, location, automatically copies the user's Electricity volume.
- Low-power, low cost, reliable, safe.
- To realize the transmission and processing of data in distance.
- Through internet, updating meter readings and faults to real time data base.
- Later Data analysis is carried out to present billing information of individual meter reading systems.
- Buzzer is turned ON to indicate “ Due bills ”
- LCD is provided to display current meter readings and energy consumption.
- Also billing information will be sent through SMS as well.
COMPONENTS REQUIRED:
- ATMEGA UNO 328.
- Two Relay shields
- GPRS Shield
- Jumper wires
- Screw shield.
- Buzzer
- LCD Shield.
