Abstract

Methods of controlling a resource demand system are disclosed. One method includes obtaining weather data from at least one data source that collects weather data at a plurality of areas. A weather value for a target location is calculated from the weather data. A weather value is sensed for the target location. The calculated weather value is compared with the sensed weather value to validate at least one of the calculated weather value and the sensed weather value, and a control value is calculated based on at least one of the calculated weather value and the sensed weather value.

Claims

1. A method of controlling a resource demand system, comprising:

obtaining weather data from at least one data source that collects weather data at a plurality of areas;

calculating a weather value for a target location from the weather data;

sensing a weather value for the target location;

comparing the calculated weather value with the sensed weather value to validate at least one of the calculated weather value and the sensed weather value;

if a difference between the calculated weather value and the sensed value is greater than a sensed margin, then determining whether the calculated weather value or the sensed weather value is accurate, comprising comparing the calculated weather value with collected weather data, wherein the collected weather data is representative of weather of at least one of the plurality of areas; and

calculating a control value based on either the calculated weather value or the sensed weather value depending upon whether the calculated weather value or the sensed weather value is determined to be accurate, wherein the calculated weather value is determined to be erroneous if the difference between the calculated weather value and the sensed value is greater than the sensed margin and the difference between the calculated weather value and the collected weather data is outside of a collected weather data margin.

2. The method of claim 1, further comprising:

providing the control value to a control device that controls the resource demand system.

3. The method of claim 2, further comprising modifying the control value based on at least one landscape specific parameter.

4. The method of claim 1,

further comprising

concluding that the sensed weather value is erroneous if the difference between the calculated weather value and the sensed value is greater than the sensed margin and the difference between the calculated weather value and the collected weather data is within a collected weather data margin.

5. The method of claim 4, further comprising if the sensed weather value is erroneous, then providing an alert that a sensor that senses the sensed weather value is faulty.

6. The method of claim 4, wherein if the sensed weather value is erroneous, then calculating the control value comprises setting the control value to be the calculated weather value.

7. The method of claim 1, further comprising if the calculated weather value is erroneous, then providing an alert that the calculated weather value is erroneous.

8. The method of claim 1, wherein if the calculated weather value is erroneous, then calculating the control value comprises setting the control value to be the sensed weather value.

9. The method of claim 1, wherein comparing the calculated weather value with the sensed weather value to validate at least one of the calculated weather value and the sensed weather value comprises:

comparing a plurality of calculated weather values against sensed weather values over time to establish a trend in differences between the calculated weather values and the sensed weather values.

10. The method of claim 9, wherein if over time the trend in the differences between the calculated weather values and the sensed weather values are determined to be an anomaly, then validating a sensor that generates the sensed weather value, and using the sensed weather value to adjust the calculated weather value.

11. The method of claim 9, wherein if over time the trend in the differences between the calculated weather value and the sensed weather value is determined to be continuous, then determining which of the calculated weather value and the sensed weather value is erroneous.

12. The method of claim 11, wherein determining which of the calculated weather value and the sensed weather value is erroneous comprises comparing a calculated weather value for a collected weather data location with collected weather data, if within a margin, then concluding that the sensed weather value is erroneous.
