Abstract

The present invention achieves technical advantages as an AMR device and system adapted to couple to utility meters and operate under Part 15 of the FCC Rules. The device and system also includes a data profile module.

Claims

1. An automated meter reading (AMR) system, comprising:

an interface module adapted to couple to a meter measuring a quantity of delivered product and providing a first signal indicative of the measured quantity, the module including a wireless transmitter modulating and transmitting the first signal as an RF signal at a user selectable transmission interval, at a power level no greater than 1 mW and at a frequency in an unlicensed frequency band, adapted to reduce interference in the unlicensed frequency band without requiring external polling and without the assistance of a wireless communications network; and

a profile module operatively coupled to the interface module and having a transceiver and a controller receiving the first signals, the profile module creating and storing usage profile data as a function of the measured quantity, wherein the usage profile data is generated at a profile data interval and is adapted to be obtained by a remote user via the transceiver.

2. The device as specified in claim 1 wherein the profile data interval is user selectable.

3. The device as specified in claim 2 wherein the profile data interval is substantially longer than the transmission interval.

4. The device as specified in claim 1 wherein the wireless transmitter transmits the modulated first signal at a fixed frequency.

5. The device as specified in claim 1 wherein the profile data interval is adapted to be selectively adjusted by a field technician.

6. The device as specified in claim 1 wherein the controller is adapted to be wirelessly polled by a remote user via the transceiver.

7. The device as specified in claim 1 wherein the device includes an internal battery and operates therefrom.

8. The device as specified in claim 1 wherein the transceiver is an IR transceiver.
