Abstract

Data relating to energy management may be collected and stored from one or more sites. This data may be analyzed by a series of rules, and each rule may look for certain patterns in the data over time. Each time a pattern is detected in the data, the rule may create and store an event back into the database. Each event may represent the detection of a specific condition that starts at a specific time and continues for a specific duration. Each rule may also dynamically assign and update a score to each event that indicates its level of importance and persistence. Once the raw data has been analyzed and events have been created that represent basic conditions, a new set of rules may analyze the events themselves, in addition to, or rather than, the raw data. Successive passes of rules can thus detect higher level, broader problems.

Claims

1. A system for detecting a pattern from one or more events comprising:

data collected from one or more sites over time wherein said data is generated from equipment for monitoring and controlling environmental conditions at said one or more sites;

one or more rules, where the one or more rules look for certain patterns in the data over time and dynamically assign and update a score to each event that indicates its level of importance; and

a processor, wherein said processor applies said data against said one or more rules to create one or more events wherein said one or more events represent a detection of a specific condition that starts at a specific time and continues for a specific duration and applies said one or more events and additional data collected from said one or more sites over time to said one or more rules to create one or more additional events wherein once the one or more additional events have been created and the additional data has been analyzed, using a new set of rules to analyze the one or more additional events wherein said one or more additional events include whether said one or more events exceeds the specific duration.

2. The system of claim 1 wherein a priority or ranking may be assigned to said one or more additional events.

3. The system of claim 1 wherein said data includes temperature, light, or humidity.

4. The system of claim 1 wherein said one or more rules are computer programs that analyze a series of said data over time.

5. The system of claim 1 wherein information concerning said one or more additional events are delivered to a user.

6. The system of claim 1 wherein said one or more additional events are compared to one another based on said one or more sites from which said additional data was collected.

7. The system of claim 1 wherein a change in said additional events over time is detected or analyzed by the processor.

8. The system of claim 1 further comprising a computer visualization system for displaying over time said one or more additional events.

9. The system of claim 1 wherein said one or more events includes one or more of a:

unique identifier, start time, finish time, event key, sensor key, category, score, and message.

10. A method for detecting a pattern from one or more events comprising:

collecting data, utilizing a processor, from one or more sites over time wherein said data is generated from equipment for monitoring and controlling environmental conditions at said one or more sites;

applying one or more rules to said data where the one or more rules look for certain patterns in the data over time; and

utilizing the results from said application of one or more rules to create one or more events wherein said one or more events represent a detection of a specific condition that starts at a specific time and continues for a specific duration, where the one or more rules dynamically assign and update a score to each event that indicates its level of importance;

applying said one or more events and additional data collected from said one or more sites over time to said one or more rules to create one or more additional events wherein once the one or more additional events have been created and the additional data has been analyzed, using a new set of rules to analyze the one or more additional events wherein said one or more additional events include whether said one or more events exceeds the specific duration.

11. The method of claim 10 wherein a priority or ranking may be assigned to said one or more additional events.

12. The method of claim 10 wherein said data includes temperature, light, or humidity.

13. The method of claim 10 wherein said one or more rules are computer programs that analyze a series of said data over time.

14. The method of claim 10 wherein information concerning said one or more additional events are delivered to a user.

15. The method of claim 10 wherein said one or more additional events are compared to one another based on said one or more sites from which said additional data was collected.

16. The method of claim 10 wherein a change in said additional events over time is detected or analyzed by the processor.

17. The method of claim 10 further comprising a computer visualization system for displaying over time said one or more additional events.

18. The method of claim 10 wherein said one or more events includes one or more of a:

unique identifier, start time, finish time, event key, sensor key, category, score, and message.
