Abstract

A host automated meter reading (AMR) device may communicate with one or more client AMR devices in proximity to the host meter. The host and client AMR devices operate as master and slave devices, respectively, in a host-client AMR device system. The host AMR device may transmit command and control functions to the client AMR devices, and may receive AMR device information from each client AMR device. The host AMR device may also transmit AMR device information from both itself and the client AMR devices over a communications network to a utility. Furthermore, the host AMR device may receive command and control functions from the utility via the same communications network, and may relay those functions to the AMR devices associated with that particular host AMR device.

Claims

1. A host automated meter reading (AMR) device, comprising:

a communication module, in communication with a plurality of client AMR devices,

wherein said communication module is operable to receive meter data associated with said plurality of client AMR devices, and is operable to transmit said meter data to a utility remote from said plurality of client AMR devices; and

a universal communications interface, local to the host meter, functionally coupled to a processor and configurable for communicating with a plurality of different types of communication devices, each different type of communication device operative to communicate with a client AMR device via one of a plurality of different communication mediums;

a slot functionally coupled to the universal communications interface and configured to interchangeably connect one of the plurality of different types of communication devices;

wherein the processor communicates with the universal communications interface to determine which one of the plurality of different types of communication devices is connected to the slot; and

wherein the processor formats the meter data into a format compatible with the connected communication device and transmits the formatted meter data to the universal communications interface for transmission to the connected communications device.

2. The host AMR device of claim 1, wherein the host AMR device further comprises at least one interface to receive meter data associated with said host AMR.

3. The host AMR device of claim 2, wherein the communication module is further operable to transmit, to the utility, the meter data associated with the host AMR.

4. The host AMR device of claim 2, wherein the communication module is further operable to receive instructions from said utility and to forward said instructions to at least one of said plurality of client AMR devices.

5. The host AMR device of claim 2, wherein said at least one interface comprises a PCMCIA slot.

6. The host AMR device of claim 1, wherein the communication module is operable to execute a request received from said utility, wherein said request is associated with at least one of said plurality of client AMR devices.

7. The host AMR device of claim 1, wherein said communications module is operable to communicate with said utility via a communications medium selected from the group of communication mediums consisting of cellular, satellite, telephone, cable, and RF modems.

8. The host AMR device of claim 1, wherein said communications module is operable to communicate with at least one of said plurality of client AMR devices via a Wi-Fi (Wireless Fidelity) communication medium.

9. The host meter communication device of claim 1, wherein said communications module is operable to communicate with at least one of the plurality of client AMR devices via a network interface card, a wireless network interface card, or a serial communications card.

10. A host-client automated meter reading (AMR) system, comprising:

at least one host AMR device, said at least one host AMR device comprising a communications module, wherein said at least one host AMR device is in communication with a utility via said communications module;

a plurality of client AMR devices, each of said plurality of client AMR devices in communication with said at least one host AMR device via said at least one host AMR device communications module; and

wherein said at least one host AMR device includes a universal communications interface, functionally coupled to a processor and configurable for communicating with a plurality of different types of communication devices, each different type of communication device operative to communicate with a client AMR device via one of a plurality of different communication mediums;

a slot functionally coupled to the universal communications interface and configured to interchangeably connect one of the plurality of different types of communication devices;

wherein the processor communicates with the universal communications interface to determine which one of the plurality of different types of communication devices is connected to the slot; and

wherein the processor formats meter data into a format compatible with the connected communication device and transmits the formatted meter data to the universal communications interface for transmission to the connected communications device.

11. The system of claim 10, wherein said communication module is operable to communicate with said utility via a communications medium selected from the group of communication mediums consisting of cellular, satellite, telephone, cable, and RF modems.

12. The system of claim 10, wherein said communication module is operable to communicate with at least one of said plurality of client AMR devices via a Wi-Fi communication medium.

13. A method of communicating between local meters and a utility, comprising:

providing a host meter;

transmitting command data from the host meter to a plurality of client meters using a short range communication capability of said host meter;

receiving, at said host meter, meter data from said client meters using a short range communication capability of said host meter;

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 meter data into a format compatible with the identified communication device; and

sending the formatted meter data to the identified communication device for subsequent transmission by the identified communication device; and

relaying the received meter data back to a utility using a long range communication capability of said host meter.

14. The method of claim 13, further comprising the step of receiving command data from a utility using the long range communication capability of said host meter.

15. The method of claim 13, wherein said long range communication capability of the relaying step is provided by a communication mediums means selected from a group consisting of a cellular, satellite, telephone, cable, and RF modems.

16. The method of claim 13, wherein said short range communication capability of the transmitting step is provided by a Wi-Fi communication medium.

17. The method of claim 13, wherein said short range communication capability of the receiving step is provided by a Wi-Fi communication medium.

18. A method of communicating between host and client meters comprising the steps of:

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 communication module configurable for communicating with each of the plurality of different types of communication devices;

formatting command data into a format compatible with the identified communication device;

sending the formatted command data to the identified communication device for subsequent transmission by the identified communication device;

transmitting from the identified communication device command data from said host meter to a plurality of client meters using a short range communication capability of said host meter; and

receiving at each of said plurality of client meters data from said host meter using another short range communication capability provided by each of said plurality of client meters.
