Automatic meter reading by using rf

Each electric utility chooses the architecture they want to deploy, sometimes under the direct or indirect influence of decisions made by state or local regulators. Peak Power Limits In addition to time-averaged public safety limits that require RF exposures to be time-averaged over a 30 minute time period, the FCC also addresses peak power exposures.

The main peculiarity of the Arduino pro-mini board is its size, and its capability of operating in the 3V supply. The physical layer method is a very different scheme than the X This state contains the RF Configuration VIs that are responsible for settings the power level, frequency, generation mode, and reference clock.

Theory Signal generators are used for testing many electronic circuits and systems by simulating the signals seen by the device under test DUT during actual use. Currently Julythere is a mandated program being planned in Victoria with a planned deployment of 2.

Automatic meter reading

Because these bands are also used by Industrial, Scientific and Medical devices, these bands are often called the ISM bands. There are already water-meters available which allow the interfacing of reed-switch. To sectionalize the transmission network and protect against failures, a "wave trap" is connected in series with the power transmission line.

In this report, the public safety limit for a smart meter is a combination of the individual antenna frequency limits and how much power output they create. The meters installed in Corpus Christi are not directly Wi-Fi enabled, but rather transmit narrow-band burst telemetry on the MHz band. On most frequencies, Part 15 permits only very low-power operation -- a few nanowatts in some cases.

If and when a smart meter uses carrier current technology: PLC is one of the technologies used for automatic meter reading.

To further reduce concerns, smart meters transmit RF energy only for short periods each day. Power line communication PLC is a method where electronic data is transmitted over power lines back to the substation, then relayed to a central computer in the utility's main office.

Download PDF Abstract As in every where automation is required to reduce the work so we decided to implement to automatic meter reading using power line communication.

Smart Metering Technology Promotes Energy Efficiency for a Greener World

Therefore the signal is filtered out from the powerline, demodulated and modulated on a new carrier frequencyand then reinjected onto the powerline again. We will cover these two loops separately as they operate independently of each other.

It has advantages in safetyreal time measuring and time saving as well as it has a better user interface and digital data analysis. Do they have potential RFI generating circuitry, such as digital circuitry. To receive the data without error at the receiver end the transmitter unit transmits the data in the following format.

Automatic meter reading

The digital readout of the smart meter requires close inspection, particularly where there is glare or bright sunlight, or low lighting conditions.

The RF hot spots created by reflection can significantly increase RF exposures to the public, even above current public safety limits. Since this system was developed pre-internet, Metretek utilized the IBM series 1 mini-computer.

Remote Monitoring Systems

Automatic Meter Reading (AMR) System using Arduino DESCRIPTION: The AMR basically has two units, a data-storage- transmitter unit that is fixed on the meter and a handheld receiver unit.
