Abstract

An electrical utility meter system measures residential energy consumption and automatically communicates this information to a host computer via the Internet. The host computer can then be accessed by the end utility customer or other authorized entities. This Internet or web based system offers two-way communication capability to support meter reconfiguration. This system is comprised of two major elements, a hardware unit and database software. The hardware unit includes a printed circuit card that is retrofitted into a form 2S single-phase residential meters. The unit measures residential energy consumption in predefined intervals, stores the measurements, and communicates at predefined times to a host database server. The unit can accommodate various wired or wireless communication technologies through a simple communications port.

Claims

1. A method for programming a programmable electric utility meter, comprising:

utilizing a handheld device to download configuration information to said electric utility meter via an optical link at said electric utility meter;

downloading Internet service provider information from said handheld device to said electric utility meter via said optical link to enable the electric utility meter to communicate with at least one Internet service provider;

transmitting a password to said meter from said handheld device via said optical link, wherein said password is valid only for a pre-determined time period and is required for said electric utility meter to communicate with a server; and

utilizing the handheld device to initiate communications between said electric utility meter and said server after said password is verified by said server.

2. A method in accordance with claim 1, comprising:

selecting said handheld device from one of a personal digital assistant or a computer.

3. A method in accordance with claim 1, comprising:

downloading a premises identification code from said handheld device to said electric utility meter via said optical link.

4. A method in accordance with claim 1, wherein:

said Internet server provider information comprises at least one telephone number.

5. A method in accordance with claim 4, comprising:

utilizing said at least one telephone number to access said server via a communications link.

6. A method in accordance with claim 1, comprising:

utilizing said handheld device to control said meter such that said electric utility meter initiates a connection via a public network communications link to said server.

7. A method in accordance with claim 6, comprising:

utilizing said handheld device to cause said electric utility meter to upload stored data to said server.

8. A method in accordance with claim 1, comprising:

utilizing said handheld device to perform field diagnostic functions with said electric utility meter via said optical link.

9. A method in accordance with claim 1, wherein said communication step comprises:

said electric utility meter responding to said handheld device to establish a TCP/IP connection to said server via a communications link over a public network.

10. A method in accordance with claim 9, comprising:

sending a message from said electric utility meter to said server indicating that it has powered up.
