Abstract

A communications network (12) for use by a utility (10) for communication, command, and control of the utility'"'"'s distribution area for gas, water and electrical services including the utility'"'"'s distribution system, security, workforce, and asset management. The network includes apparatus for obtaining information and data concerning usage of the electricity, gas, or water by each of the utility'"'"'s customers, the operation of installations throughout the system, and how electricity, gas, or water is being distributed throughout the system. The information and data from each source (16) is processed to provide an up-to-date overview of the system and its operation to the utility'"'"'s management and operating personnel. This includes identification of any current problems, including distribution or security, within the system, and asset monitoring and management to identify possible future problems which may occur within a predetermined period of time. Reports generated as a result of processing the information and data, besides providing current status information, also provide management and operating personnel with information as to ways of alleviating any current problems identified within the system, and steps which can be taken to forestall possible future problems which are identified.

Claims

1. A communications network for use by a utility for communication, command, and control of the utility'"'"'s commodity distribution system comprising:

apparatus obtaining information and data concerning each customer'"'"'s usage of the commodity supplied by the utility, operation of the utility'"'"'s distribution system to supply the commodity to the customers, and distribution of the commodity throughout the system;

means processing the information and data from each source thereof to provide an up-to-date overview of the system and its operation, to identify any current problems within the system, and to identify possible future problems within the system which may occur within a predetermined period of time; and

,

to provide system management with reports on the current status of the system, ways of alleviating any current problems identified within the system, and steps which can be taken to forestall any identified possible future problems.

2. A multi-tier communications network for use by a utility for communication, command, and control of the system comprising:

a first tier including apparatus obtaining information and data concerning usage by each customer of a commodity supplied by the utility, operation of the utility'"'"'s distribution system, and the distribution of the commodity throughout the system;

a second tier to which the information and data gathered from customer facilities within a defined geographic area comprising a portion of the first tier is communicated, the second tier including a data collection means within each geographic area which receives and collects the information and data; and

,

a third tier to which the information and data gathered by each data collection means is communicated, the third tier including a network operations center for collecting and evaluating all the information and data from the system to determine a current operational status of the utility'"'"'s distribution system.

3. The communications network of claim 2 in which information and data is communicated from customer facilities within a defined geographic area to the data collection means for that area at one frequency, and from the data collection means to the network operations center at a second frequency.

4. The communications network of claim 2 wherein each network operations center collects information and data from more than one data collection means.

5. The communications network of claim 4 wherein the data collection means in one geographic area communicates the information and data collected by the data collection means to a data collection means in an adjacent geographic area thereby to establish an alternate communications path between the data collection means and the network operations center.

6. The communications network of claim 5 in which the third tier further includes a plurality of regionally spaced towers to which information and data collected by data communication means within a region are communicated, the towers communicating with the network operations center.

7. The communications network of claim 6 in which the data collection means in one region communicates with a tower in an adjacent region thereby to establish an alternate communications path between the data collection means in the one said region and the network operations center.

8. The communications network of claim 2 further including a relay data collection means interposed in each path between a data collection means and the network operations center to facilitate transmissions between each data collection means and the network operations center.

9. The communications network of claim 3 in which communications between facilities and a data collection means is at a frequency of approximately 450 MHz.

10. The communications network of claim 9 in which communications between the data collection means and the network operations center is at a frequency of approximately 900 MHz.

11. The communications network of claim 3 in which the data collection means, when it has collected a requisite amount of information, executes a call-up protocol to access the network operations center and transfer its collected information.

12. The communication network of claim 2 in which the utility supplies electricity.

13. The communication network of claim 2 in which the utility supplies gas.

14. The communication network of claim 2 in which the utility supplies water.

15. The communication network of claim 2 for concurrent use by at least two utilities each of which supplies a different commodity.
