Abstract

In a data collection system having a utility data collector configured for remotely collecting utility data, a system includes one or more endpoints. Each endpoint has a utility meter, memory for storing at least utility consumption data from the utility meter, and a radio for transmitting a communication message to the utility data collector. The radio establishes a communication link between the endpoint and the utility data collector, and provides consumption data when a wireless communication channel quality test determines an adequacy of communications from the endpoint and the utility data collector (e.g. using RSSI). The utility meter sets a hold-off timer or other validity check and only performs subsequently received reset requests or other reconfigurations if the timer has expired or the validity check is valid. Other features are also disclosed.

Claims

1. At a utility data collector configured for remotely collecting utility data from one or more endpoints that include a utility meter, a method comprising:

receiving a one-way type communication message from the endpoint, wherein the endpoint and the utility data collector are configured to communicate with each other using both one-way and two-way communications;

based on receiving the one-way type communication message, performing a received signal strength indicator (RSSI) test to determine an adequacy of a communication link to be established between the endpoint and the utility data collector; and

if a threshold is met for the RSSI test, initiating two-way communications between the endpoint and the utility data collector to gather at least utility consumption data.

2. The method of claim 1 wherein utility meter is configured for reading peak demand values and wherein the two-way communications include sending a demand reset command to the endpoint.

3. The method of claim 1 wherein performing the RSSI test includes measuring an amplitude of at least one received one-way type communication message packet.

4. The method of claim 1 wherein performing the RSSI test includes considering a signal-to-noise ratio associated with the received one-way type communication message.

5. The method of claim 1 wherein the received one-way type message is a bubble-up message.

6. In a data collection system having a utility data collector configured for remotely collecting utility data, a system comprising:

one or more endpoints, wherein each endpoint comprises;

a utility meter;

memory means for storing at least utility consumption data from the utility meter;

radio means for transmitting a communication message to the utility data collector; and

,

wherein the radio means further comprises means for establishing a communication link between the endpoint and the utility data collector, and for providing at least the utility consumption data from the utility meter, when a wireless communication channel quality test determines an adequacy of communications from the endpoint and the utility data collector.

7. The system of claim 6 wherein the wireless communication channel quality test is a received signal strength indicator (RSSI) test, and wherein the utility data collector performs the RSSI test.

8. The system of claim 6 wherein utility meter and memory means are configured for reading and storing peak demand values, and wherein the radio means further comprises two-way communications means for receiving a demand reset command.

9. The system of claim 6 wherein the communications message is a one-way bubble-up message.

10. The system of claim 6 wherein the radio means further comprises means for receiving a command for correcting a clock of the endpoint, changing a time of use (TOU) schedule, or configuration programming of the storage means.

11. At a utility endpoint configured to communicate wirelessly with a utility data collector system over a radio communication link, the endpoint comprising a utility meter configured, at least in part, for reading peak demand data, a method comprising:

receiving a first request for a demand reset from the utility data collector system;

based on receiving the first request, performing the requested demand reset and setting a demand reset hold-off timer; and

if a subsequent request for a demand reset is received during a period associated with the demand reset hold-off timer, not performing the subsequently requested demand reset unless the demand reset hold-off timer has expired.

12. The method of claim 11 wherein the demand reset hold-off timer expires approximately one day after being set, and wherein a timer period may be user-programmable to other durations.

13. The method of claim 11 further comprising, if a subsequent request for a demand reset is received before the demand reset hold-off timer has expired, setting a flag to indicate receipt of the request.

14. In a system where a utility endpoint communicates wirelessly with a utility data collector over a radio communication link, wherein the utility endpoint gathers utility consumption data, an apparatus comprising:

means for receiving a first reset request message from the utility data collector;

means for performing a first requested reset, wherein the first requested reset requests reconfiguration of at least a portion of the utility endpoint;

means for receiving a second reset request message; and

,

means for performing a validity check and performing a second requested reset only if the validity check is acceptable.

15. The apparatus of claim 14 wherein the means for performing a validity check comprises means for a setting a hold-off timer based on the first reset request message or the first requested reset, and not performing the second requested reset during a period associated with the hold-off timer.

16. The apparatus of claim 14 wherein the means for performing a validity check comprises means for comparing sequence counter values.

17. The apparatus of claim 14 wherein the means for performing a validity check comprises means for receiving a confirming message after successful receipt of utility consumption data by the utility data collector.

18. The apparatus of claim 14 wherein the first requested reset comprises performing a demand reset, correcting a clock of the utility endpoint, changing a time of use (TOU) schedule of the utility endpoint, or configuration programming of storage means of the utility endpoint.
