Abstract

A method of communicating with automation components configured for use within a building automation system is disclosed. The method includes determining a first communication schedule such that the first communication schedule configured to govern an activity schedule for use by an automation component, communicating the first communication schedule to the automation component such that the automation component currently implements a second communication schedule to govern the activity schedule, and adjusting the second communication schedule to equal the communicated first communication schedule such that the activity schedule increases a communication frequency in response to the adjustment. The method may further include defining a duration during which the first communication schedule equals the second communication schedule.

Claims

1. A method of communicating with automation components configured for use within a building automation system, the method comprising:

determining a first communication schedule, the first communication schedule configured to govern an activity schedule for use by an automation component, the first communication schedule being to direct activation of the automation component for communication;

defining a duration of time the first communication schedule is to be implemented;

communicating the first communication schedule and the duration of time the first communication schedule is to be implemented to the automation component, wherein the automation component currently implements a second communication schedule to govern the activity schedule;

adjusting the second communication schedule to equal the communicated first communication schedule, wherein the activity schedule increases a communication frequency in response to the adjustment from the second communication schedule to the communicated first communication schedule; and

implementing the second communication schedule once the duration of time elapses after the adjustment.

2. The method of claim 1, wherein determining the first communication schedule includes identifying a target communication frequency.

3. The method of claim 2, wherein identifying the target communication frequency includes identifying a duration.

4. The method of claim 1, wherein the activity schedule includes a first period associated with an inactive period and a second period associated with an active period, wherein the first period is longer than the second period.

5. The method of claim 1, wherein the first communication schedule directs the automation component to activate for communication one second out of every two seconds.

6. The method of claim 1, further comprising:

establishing a direct communication link between the automation component and a device.

7. The method of claim 1, wherein the device is a mobile device.

8. The method of claim 1, wherein communicating the first communication schedule to the automation component includes communicating the first communication schedule to the automation component via a second automation component.

9. A mobile device for communicating with automation components within a building automation system, the mobile device comprising:

a processor in communication with a memory, the processor configured to;

determine a first communication schedule, the first communication schedule configured to govern an activity schedule for use by an automation component, the first communication schedule to direct activation of the automation component for communication;

define a duration of time the first communication schedule is to be implemented;

communicate the first communication schedule and the duration of time the first communication schedule is to be implemented to the automation component via a wireless communication component, wherein the automation component currently implements a second communication schedule to govern the activity schedule; and

adjust the second communication schedule within the automaton component to equal the communicated first communication schedule for the communicated duration of time the first communication schedule is to be implemented, wherein the activity schedule increases a communication frequency in response to the adjustment from the second communication schedule to the communicated first communication schedule.

10. The device of claim 9, wherein the processor is configured to utilize a target communication frequency to determine the first communication schedule.

11. The device of claim 10, wherein the target communication frequency includes a duration.

12. The device of claim 9, wherein the activity schedule includes a first period associated with an inactive period and a second period associated with an active period, wherein the first period is longer than the second period.

13. The device of claim 9, wherein the first communication schedule directs the automation component to activate for communication one second out of every two seconds.

14. The device of claim 9, wherein the wireless communication component is configured to establish a direct communication link to the automation component.

15. The device of claim 9, wherein the communicated first communication schedule to the automation component is communicated to the automation component via a second automation component.
