Abstract

A method and system of optimally adjusting the environment of a predetermined location based upon the movement of a mobile communication device using location-based services.

Claims

1. A method of adjusting control devices of a building automation system (BAS), the method including the steps of:

determining recovery time for an environmental control system that is in a first energy mode for a predetermined location;

generating a first geo-fencing perimeter, where the first geo-fencing perimeter is associated with movement of a user and the recovery time; and

changing the environmental control system from the first energy mode to a second energy mode based upon the proximity of the mobile communications device to the first geo-fencing perimeter.

2. The method of claim 1, where the proximity of the first geo-fencing perimeter is determined by a crossing of the first geo-fencing perimeter.

3. The method of claim 1, further including the steps of:

generating a second geo-fencing perimeter; and

calculating a return time from a travel time and a distance the mobile communications device travels between the second geo-fencing perimeter and the first geo-fencing perimeter along with a distance to the predetermined location.

4. The method of claim 1 includes, determining the proximity to the first geo-fencing perimeter with location information from a mobile communications device carried by the user that is configured to communicate with the BAS.

5. The method of claim 4, where determining the proximity of the first geo-fencing perimeter further includes identifying the proximity of the first geo-fencing perimeter at the mobile communications device.

6. The method of claim 4, where determining the proximity of the first geo-fencing perimeter further includes identifying the proximity of the first geo-fencing perimeter at the BAS using the location information from the mobile communications device.

7. The method of claim 1, where determining the recovery time of the environmental system uses historical operational data associated with operation of the environmental system and the predetermined location.

8. The method of claim 1, includes placing the predetermined location in the first energy mode when a user leaves the predetermined location.

9. The method of claim 1, includes detecting that no one is in the predetermined location;

and

placing the predetermined location in the first energy mode.

10. A system for adjustment of control devices in a building automation system (BAS), comprising:

a processor in an environmental control system that determines a recovery time for a predetermined location that is in a first energy mode when changed to a second energy mode;

a first geo-fencing perimeter generated by the processor, where the first geo-fencing perimeter is associated with movement of a mobile communication device and the recovery time, where the environmental control system changes from the first energy mode to the second energy mode based upon the proximity of the user to the first geo-fencing perimeter.

11. The system of claim 10, where the proximity of the first geo-fencing perimeter is determined by the BAS detection of the first geo-fencing perimeter being crossed by the mobile communications device.

12. The system of claim 10, further includes;

a second geo-fencing perimeter generated by the processor; and

a return time calculated from a travel time associated with the mobile communications device reported to the BAS, a distance the user travels between the second geo-fencing perimeter and the first geo-fencing perimeter along with a distance to the predetermined location.

13. The system of claim 10, where the proximity to the first geo-fencing perimeter is determined with location information from a mobile communications device that is configured to communicate with the BAS.

14. The system of claim 13, where the proximity of the first geo-fencing perimeter determination further includes identification of the proximity of the first geo-fencing perimeter at the mobile communications device.

15. The system of claim 13, where the proximity of the first geo-fencing perimeter determination further includes identification of the proximity of the first geo-fencing perimeter with a processor in the BAS using the location information from the mobile communications device.

16. The system of claim 10, where the recovery time of the environmental system uses historical operational data associated with operation of the environmental system and the predetermined location.

17. The system of claim 10, includes the predetermined location being placed in the first energy mode when a user leaves the predetermined location.

18. The system of claim 10, includes at least one sensor that detects that no one is in the predetermined location;

and

placing the predetermined location in the first energy mode in response to detection of no one in the predetermined location.

19. A non-transient computer-readable medium with a plurality of instructions for a method of adjusting control devices of a building automation system (BAS), the instructions including the steps of:

determining recovery time for an environmental control system that is in a first energy mode for a predetermined location;

generating a first geo-fencing perimeter, where the first geo-fencing perimeter is associated with movement of a mobile communications device and the recovery time; and

changing the environmental control system from the first energy mode to a second energy mode based upon the proximity of the mobile communication device to the first geo-fencing perimeter.

20. The non-transient computer-readable medium with a plurality of instructions for a method of adjusting control devices of a building automation system (BAS) of claim 19, where the proximity of the first geo-fencing perimeter is crossing the first geo-fencing perimeter.

21. The non-transient computer-readable medium with a plurality of instructions for a method of adjusting control devices of a building automation system (BAS) of claim 19, further including the steps of:

generating a second geo-fencing perimeter; and

calculating a return time from a travel time and a distance the mobile communication device between the second geo-fencing perimeter and the first geo-fencing perimeter along with a distance to the predetermined location.
