Problems solved by technology

This round-robin is slow and consumes processing and communication resources
Also, if the communication link between the concentrator and the terminal is broken by intentionally isolating the substation from the wires through a power failure, current systems generally do not have the capability to re-establish communication between the terminal and an alternate concentrator

Embodiment Construction

[0020] Various embodiments of the present invention are described in detail below with reference to the drawings, in which like numerals represent like parts and assemblies throughout the several views. Reference to different embodiments does not limit the scope of the invention, which is only limited by the scope of the appended claims. Additionally, any examples set forth in this specification are not intended to be limiting but merely to suggest a few of the many possible embodiments for the claimed invention.

[0021] figure 1 is a block diagram illustrating one link of a power distribution system 100 that distributes power between distribution substations and customer equipment at power consumers. An electrical distribution system, or as it is sometimes referred to, is a part of a power system that receives power from generating equipment via high-voltage transmission lines, reduces or steps down the voltage, and then distributes the power to terminals at energy users' p...

Abstract

A system for receiving and processing signals received from a plurality of endpoints. Each endpoint includes an endpoint transmitter in electrical communication with a power distribution line within a power distribution system. The system comprises a power line coupler. A substation receiver is in electrical communication with the power line coupler. A substation circuit is in electrical communication with the substation transceiver. The substation circuit is configured to simultaneously demodulate signals received from the plurality of different endpoints.

Description

[0001] This application is filed as a PCT International Application in the name of Hunt Technologies, Inc., USA, claiming U.S. Patent Application No. 10 / 626495, filed July 24, 2003, U.S. Patent Application No. 10 / 626496, filed July 24, 2003, and Priority to U.S. Patent Application No. 10 / 626,465, filed July 24, 2003. technical field [0002] The present invention relates generally to data communications, and more particularly to data communications over power lines. Background technique [0003] As is true for most companies, utility companies strive to reduce business overhead costs while providing convenience to customers. For example, utilities are transitioning away from costly and time-consuming manual methods of determining the amount of electricity consumed by utility customers. Traditionally, personnel regularly visit the customer's home and ask to come in to read the customer's electricity usage from the meter. This approach is costly, slow and disruptive to custo...
