Abstract

The present invention achieves technical advantages as an AMR device adapted to couple to utility meters and detect an excess rate of product delivery and responsively generate an alert indicative of this excess rate. Advantageously, the alert is provided to a remote device to provide notice of an abnormal condition, such as a leak which could produce flooding, or customer exceeding an allowed delivery rate, such as during conservation periods.

Claims

1. A device for coupling to a meter measuring a quantity of delivered product, comprising:

an interface module adapted to couple to the meter and to provide a first signal indicative of the measured quantity;

a wireless transmitter, responsively coupled to the interface module and adapted to modulate and transmit the first signal as an RF signal at a transmission interval, at a power level no greater than 1 mW and at a frequency in an unlicensed frequency band, and further adapted to reduce interference in the unlicensed frequency band without requiring external polling and without the assistance of a wireless communications network;

a profile module having a transceiver and a controller adapted to receive the first signal and to create and store 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; and

an alarm system adapted to generate an alarm when the measured quantity exceeds a programmable threshold, wherein the threshold is adapted to be remotely established.

2. The device of claim 1 wherein the alarm system further comprises a programmable consumption profile.

3. The device of claim 1 wherein the threshold is indicative of a restriction established by a government entity.

4. The device of claim 1 wherein the threshold is a function of time.

5. The device of claim 1 wherein the alarm system is adapted to be remotely reset.

6. The device of claim 1 wherein the alarm system automatically resets based on the product delivery data.

7. A device for coupling to a meter measuring product delivery, comprising:

an interface module adapted to couple to the meter, the interface module adapted to provide a first signal indicative of the product delivery; and

a profile module having a transmitter, and a controller adapted to receive the first signal, the profile module adapted to create and store usage profile data as a function of the product delivery, wherein the profile module has a programmable threshold, the controller adapted to responsively create at least one alert when the product delivery exceeds the programmable threshold, wherein the programmable threshold is remotely programmable.

8. The device of claim 7 wherein a first signal indicative of the product delivery is a signal indicative of instantaneous product delivery.

9. The device of claim 7 wherein the threshold is indicative of a restriction imposed by a governmental entity.

10. The device of claim 7 wherein the transmitter is adapted to send data representative of a product delivery parameter at an interval and the alert independent of the interval.

11. The device of claim 7 wherein the device alert is adapted to be reset remotely from the device.

12. The device of claim 7 wherein the transmitter transmits the alert at a first frequency and data representative of a product delivery parameter at a second frequency.

13. The device of claim 7 wherein the threshold is a function of a time.

14. The device of claim 7 wherein the alarm system is adapted to automatically reset based on the product delivery data.

15. A device for coupling to a meter measuring a quantity and time of delivered product, comprising:

an interface module adapted to couple to the meter, the interface module providing a first signal indicative of the measured quantity,

a wireless transmitter, responsively coupled to the interface module, modulating and transmitting the first signal as an RF signal at a 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 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.

16. The device as specified in claim 15 wherein the profile data interval is user selectable.

17. The device as specified in claim 16 wherein the profile data interval is substantially longer than the transmission interval.

18. The device as specified in claim 17 wherein the wireless transmitter transmits the modulated first signal at a fixed frequency.

19. The device as specified in claim 15 wherein the profile data interval is adapted to be selectively adjusted by a field technician.

20. The device as specified in claim 15 wherein the controller is adapted to be wirelessly polled by a remote user via the transceiver.

21. The device as specified in claim 15 wherein the device includes an internal battery and operates therefrom.

22. The device as specified in claim 20 wherein the transceiver is an IR transceiver.
