Abstract

A method and system for monitoring utility meter status, and transmitting a status message via an output device connected to a universal communications interface in the event that the utility meter status meets a predetermined condition. Typically, the predetermined condition is a power loss, signified by a drop in voltage or current. The system is connected to a utility meter, such as an electric meter. The voltage level of the electric meter is monitored through a voltage input interface. An analog-to-digital converter transforms the voltage waveform into a series of digital is data packets, which are then transmitted to a microprocessor. The microprocessor monitors the digital signal for a power loss indication, or other predetermined condition. Once a predetermined condition is met, the microprocessor transmits a status message across a universal serial bus to a universal communications interface. The universal communications interface is connected to at least one slot, which contains at least one output device. The universal communications interface is further able to determine the proper signal format employed by the output device for information transmission. Upon receipt of the status message, the universal communications interface converts the status message to the signal format employed by the output device, and passes the converted status message to the output device via the slot. The output device may then transmit the status message to a remote receiver in order to quickly and accurately update distant locations regarding the utility meter.

Claims

1. A system for monitoring a utility status, comprising:

a universal communications interface configurable for communicating with a plurality of different types of communication devices, each communication device operative to communicate with a corresponding receiving device via one of a variety of different communications mediums;

a processor, in communication with the universal communications interface, wherein the processor is operable to;

receive a utility signal;

generate a status message based at least in part on the utility signal;

identify a connected communication device, of the plurality of different types of communication devices, connected to the universal communications interface;

format the status message into a format compatible with the connected communication device; and

send the formatted status message to the connected communication device for subsequent transmission by the connected communication device.

2. The system of claim 1, wherein the processor comprises a utility meter processor.

3. The system of claim 1, wherein the utility signal comprises an analog wave form;

and

wherein the universal communications interface comprises an analog-to-digital converter operative to convert the analog wave form into a digital signal.

4. The system of claim 1, wherein the utility signal is received from a connect/disconnect monitor of a utility meter.

5. The system of claim 1, wherein the utility signal is received from a tamper detection monitor of a utility meter.

6. The system of claim 1, wherein the utility signal is received from a voltage monitor of a utility meter.

7. The system of claim 1, wherein the utility signal is received from a current monitor of a utility meter.

8. The system of claim 1, wherein the utility signal is received from an outage notification monitor of a utility meter.

9. The system of claim 1, further comprising a memory storage connected to the processor for storing computer-executable instructions executed by the processor;

and

wherein said computer-executable instructions cause the processor to determine whether the utility status signal exceeds a threshold value and, if so, to generate the status message.

10. The system of claim 9, wherein the memory storage further stores data relating to signal formats compatible with each of the plurality of different types of communication devices.

11. The system of claim 1, wherein the universal communications interface and processor reside within a utility meter.

12. The system of claim 1, wherein the universal communications interface is operable to interchangeably connect with each of the plurality of different types of communication devices.

13. A method of monitoring utility status, comprising:

receiving a utility signal;

generating a status message based at least in part on the utility signal;

identifying a communication device, of a plurality of different types of communication devices each operative to communicate via a respective one of a variety of different communications mediums, wherein the communication device is connected to a universal communications interface configurable for communicating with each of the plurality of different types of communication devices;

formatting the status message into a format compatible with the identified communication device; and

sending the formatted status message to the identified communication device for subsequent transmission by the identified communication device.

14. The method of claim 13, wherein receiving a utility signal comprises receiving a utility signal at a processor.

15. The method of claim 14, wherein generating a status message comprises generating a status message, at the processor, based at least in part on the utility signal.

16. The method of claim 13, wherein sending the formatted status message comprises sending the formatted status message from the processor to the identified communication device for subsequent transmission by the identified communication device.
