Abstract

A system for visually detailing the layout of a wireless network and for providing performance statistics regarding the network. Graphical diagrams are generated in accordance with a request wherein the diagrams illustrate nodes and data collectors in the wireless network. The nodes record data related to a commodity usage and transmit the data to the collectors, which in turn transmit aggregated data from a plurality of nodes to a central data collection server.

Claims

1. A system comprising:

a wireless network comprising a collector and a plurality of meters that communicate wirelessly with the collector, each of the meters having a wireless communication path to the collector that is either a direct path or an indirect path through one or more intermediate meters that serve as repeaters, the wireless communication paths between each meter and the collector defining a layout of the network;

a data collection server that receives from the collector operational data concerning the collector and each of the meters; and

a network management system that maintains a database of states of the collector and the meters,

wherein state changes of the collector and the meters are received by said data collection server and forwarded to said network management system, and wherein said network management system provides reports on said wireless network in accordance with said state changes.

2. The system of claim 1, wherein said database maintained by said network management system comprises a current network state database and a historical network state database.

3. The system of claim 2, said network management system comprising:

a user interface for receiving requests; and

a graph rendering tool that receives said requests and renders a graphical view of said network layout.

4. The system of claim 3, wherein said network management system retrieves network state information from said historical network state database to produce said graphical view.

5. The system of claim 3, wherein said graphical view is configurable via said user interface to visually identify predetermined performance parameters.

6. The system of claim 3, wherein said graph rendering tool operates independent of said user interface and produce said graphical view in response to said state changes, and

wherein said network management system stores said graphical view until requested.

7. The system of claim 5, wherein the predetermined performance parameters include a reading performance between each meter and the collector.

8. A system for providing a graphical view of a network layout, comprising:

a data collection server that receives operational data from a wireless network that comprises a collector and a plurality of meters that communicate wirelessly with the collector, each of the meters having a wireless communication path to the collector that is either a direct path or an indirect path through one or more intermediate meters that serve as repeaters, the wireless communication paths between each meter and the collector defining a layout of the network;

a network management system that maintains a database of states of the collector and the meters; and

a graph rendering tool that renders a graphical view of said network layout in accordance with said states of the collector and the meters,

wherein state changes of the collector and the meters are received by said data collection server and forwarded to said network management system, and wherein said network management system provides reports on said network layout in accordance with said state changes.

9. The system of claim 8, wherein said database maintained by said network management system comprises a current network state database and a historical network state database.

10. The system of claim 9, said network management system further comprising a user interface for receiving requests for said graphical view.

11. The system of claim 10, wherein said network management system retrieves network state information from said historical network state database to produce said graphical view.

12. The system of claim 10, wherein said graphical view is configurable via said user interface to visually identify predetermined performance parameters.

13. The system of claim 10, wherein said graph rendering tool operates independent of said user interface and produce said graphical view in response to said state changes, and

wherein said network management system stores said graphical view until requested.

14. The system of claim 12, wherein the predetermined performance parameters include a reading performance between each meter and the collector.

15. A method for providing a graphical view of a network layout, comprising:

receiving operational data from a wireless network that comprises a collector and a plurality of meters that communicate wirelessly with the collector, each of the meters having a wireless communication path to the collector that is either a direct path or an indirect path through one or more intermediate meters that serve as repeaters, the wireless communication paths between each meter and the collector defining a layout of the network;

maintaining a database of states of the collector and the meters in accordance with said operational data; and

rendering a graphical view of said network layout in accordance with said states of the collector and the meters.

16. The method of claim 15, wherein maintaining said database includes maintaining a current network state database and a historical network state database.

17. The method of claim 16, further comprising:

retrieving network state information from said historical network state database; and

producing said graphical view.

18. The method of claim 15, further comprising configuring said graphical view via a user interface to visually identify predetermined performance parameters.

19. The method of claim 15, further comprising:

automatically producing said graphical view in response to state changes; and

storing said graphical view until requested.

20. The method of claim 18, wherein the predetermined performance parameters include a reading performance between each meter and the collector.
