Embodiment Construction

[0026] figure 1 An exemplary system is shown in which the invention may be practiced. The system includes a meter 10 that operates in accordance with the principles of the present invention. Meter 10 is communicatively coupled with a plurality of external computers, such as external computers 26 and 28, via a computer network 24, such as the Internet. Of course, network 24 may be any computer network, such as a local area network (LAN) or a wide area network (WAN) that supports communications between computers on network 24 and meters 10 .

[0027] The meter 10 includes a signal processing component 15 , a processor 18 , a display 20 and a communication circuit 22 . Meter 10 may also include other communication circuitry employing other communication networks such as dedicated line networks, wireless and / or cellular networks. Such devices allow for remote meter reading, reporting of power outages and other functions as known in the art.

[0028] The signal processing means...

Abstract

A utility meter is able to receive programs for adding functionality to the meter over a computer network. The meter includes an interpreter for executing an interpretive language program and a computer network access port for receiving an interpretive language program from another computer over a computer network. The interpreter executes the interpretive language program to provide a meter function for the utility meter. In one embodiment, the interpreter is a Java Virtual Machine that interprets Java applets or Java scripts. The ability to write meter functions in a machine independent language such as Java or Active X enables utility customers to write and download additional functionality to meters over the Internet without requiring the meter manufacturer to develop a meter function program.

Description

[0001] This application claims the benefit of US Provisional Application No. 60 / 325,031, filed September 25,2001. field of invention [0002] The present invention relates to utility meters, and more particularly, to utility meters including one or more programmable processors for performing the functions of the meters. Background of the invention [0003] Demand meters, such as electric demand meters, often employ microprocessors to obtain comprehensive information about the consumption of goods by the facility or system to which the demand meters are connected. In the past, mechanical counter meters could only provide limited information, such as the cumulative total of electricity, gas, and water consumed. However, current processor-based meters are capable of usage analysis such as load profiling, which is already known in the electricity metering industry, demand analysis to identify high demand periods of the day or month, Time of use metering of cost rates varying by...
