Abstract

A communication system transmits data between a plurality of locations. The communication system is suitable for use by a utility provider to monitor a plurality of metering devices from a remote location. The communication system in accordance with use by a utility provider to monitor metering devices comprises a control for at least receiving data, a plurality of metering devices arranged in a defined number of metering groups for transmitting data associated with an amount of usage of a utility, and a defined number of concentrators, each operably connected to the control and one metering group for transmission of data between the control and plurality of metering devices.

Claims

1. A remote two-way communication system comprising:

a relay having a code-division multiple access (CDMA) communication link for carrying data;

at least one servicing device for measuring a local parameter, and for transmitting data over said CDMA communication link to said relay in response to said measurement, and for receiving data over said CDMA communication link from said relay; and

a control device for receiving over said CDMA communication link from said relay data transmitted by said at least one servicing device corresponding to said measurement of said local parameter, said control device further for transmitting over said CDMA communication link to said relay data received by said at least one servicing device including instructions for said at least one servicing device to measure said local parameter, whereby data is transmitted in two directions between said at least one servicing device and said control device by being passed through said relay.

2. A system of claim 1 further comprising a user interface for communicating information corresponding to said local parameter and said data transmitted by said control device to said at least one servicing device.

3. A system of claim 2 wherein said user interface is in communication with said control device, said user interface being regulated in response to said data from said control device.

4. A system of claim 3 wherein said user interface further communicates information corresponding to regulation of said user interface.

5. A system of claim 1, wherein said first servicing device comprises a metering device and with said metering device comprising means for measuring local usage and for transmitting said data corresponding to said measured local usage.

6. A system of claim 5, wherein said at least one servicing device comprises a plurality of metering devices, with said plurality of metering devices each comprising means for measuring local usage and with said plurality of metering devices transmitting a plurality of data associated with said measured local usage in response to a plurality of data from said control device.

7. A system of claim 6, wherein said plurality of metering devices are arranged in a defined number of metering groups, with each said metering group comprising a selected number of said plurality of metering devices, and wherein said system further comprises a defined number of relays, with each relay being in communication with said control device and one metering group.

8. A system for remote two-way meter reading comprising:

a metering device comprising means for measuring usage and for transmitting data associated with said measured usage in response to receiving a read command;

a control for transmitting said read command to said metering device and for receiving said data associated with said measured usage transmitted from said metering device; and

a relay for code-division multiple access (CDMA) communication between said metering device and said control, wherein said data associated with said measured usage and said read command is relayed between said control and metering device by being passed through said relay.

9. The system of claim 8 further comprising:

a plurality of metering devices, with each said plurality of metering devices comprising means for measuring usage and for transmitting data associated with said measured usage in response to receiving a read command, wherein said plurality of metering devices are arranged in a defined number of metering groups, with each said metering group comprising a selected number of said plurality of metering devices; and

a defined number of relays, with each relay being in communication with said control and one metering group.

10. The system of claim 9 further comprising a user interface for communicating information corresponding to said measured usage.

11. The system of claim 10 further comprising a remote device in communication with said control, said remote device being regulated in response to a control message from said control.

12. The system of claim 11, wherein said user interface communicates information corresponding to regulation of said remote device.

13. The system of claim 12, wherein said remote device is in communication with control means by said metering device.
