Method and device for communicating change-of-value information in a building automation system
View Patent ↗An automation component configured for wireless communication within a building automation system includes a wireless communications component, a processor in communication with the wireless communications component, and a memory in communication with the processor. The memory configured to store computer readable instructions which are executable by the processor to process a change-of-value message received via the wireless communications component, generate a change-of-value update in response to the change-of-value message, and communicate the change-of-value update via the wireless communication component. This change-of-value can occur in a polled (pull) fashion, or in a pushed (when it occurs) fashions.

generate a change-of-value update in response to the change-of-value request message, wherein the change-of-value update includes a plurality of change-of-value messages received from a plurality of devices; and
communicate the change-of-value update via the wireless communication component at regular intervals according to a schedule or until a change-of-value acknowledgment is received.
2. The automation component of claim 1 , wherein the change-of-value request message is received from a wireless device.
3. The automation component of claim 2 , wherein the wireless device is a ZigBee-compliant device, a terminal equipment controller, a wireless room temperature sensor, a reduced function device, or a full function device.
4. The automation component of claim 1 , wherein the change-of-value update is a change-of-value response message.
5. The automation component of claim 1 , wherein the change-of-value update is automatically communicated.
6. The automation component of claim 1 , wherein the change-of-value update is pulled to a field panel transceiver in response to the reception of the change-of-value request message by the wireless communication component.
7. The automation component of claim 6 , wherein the computer readable instructions are further programmed to:
process an acknowledgment message communicated by the field panel transceiver in response to the change-of-value update.
8. A method of communicating information between automation components operating within a building automation system, the method comprising:
detecting an indication representing a change-of-value;
generating a change-of-value update that includes a plurality of change-of-value messages received from a plurality of devices;
repetitively communicating the change-of-value update in response to the detected indication;
receiving an acknowledgment of the communicated change-of-value update; and
terminating communication of the change-of-value update in response to the received acknowledgement.
9. The method of claim 8 , wherein the indication is a sensor reading, a temperature indication, or an actuator position.
10. The method of claim 8 , wherein at least one of the plurality of change-of-value messages includes the change-of-value and a device indicator.
11. The method of claim 8 , wherein communicating the change-of-value update includes automatically communicating the change-of-value update.
12. The method of claim 8 , wherein communicating the change-of-value update includes pushing the change-of-value update to a communicatively coupled wireless device.
13. An automation component configured for wireless communication within a building automation system, the automation component comprising:
a wireless communications component;
a processor in communication with the wireless communications component;
a memory in communication with the processor, the memory configured to store computer readable instructions which are executable by the processor;
wherein the computer readable instructions are programmed to:
receive at least one change-of-value update via the wireless communications component, wherein the change-of-value update includes a plurality of change-of-value messages received from a plurality of devices;
storing the at least one change-of-value update corresponding to at least one wireless device; and
communicate the at least one change-of-value update in response to a polling request and repeat the at least one change-of-value update at regular intervals according to a schedule or until a change-of value acknowledgment is received.
14. The automation component of claim 13 , wherein the change-of-value update is received from a wireless device selected from a Zig Bee-compliant device, a terminal equipment controller, a wireless room temperature sensor, a reduced function device, or a full function device.
15. The automation component of claim 13 , wherein the change-of-value update is a pushed communication.
16. The automation component of claim 13 , wherein the computer readable instructions are further programmed to:
communicate an acknowledgment in response to the received at least one change-of-value update.
17. A method of communicating information between automation components operating within a building automation system, the method comprising:
receiving a plurality of change-of-value messages from a plurality of wireless devices, each of the plurality of change-of-value messages representing a wireless device indication;
storing the received change-of-value messages according to the corresponding wireless device of the plurality of wireless devices; and
communicating a change-of-value update that includes the plurality of change-of-value messages, and repeating the change-of-value update at regular intervals according to a schedule or until a change-of-value acknowledgment is received.
18. The method of claim 17 , wherein the wireless device indication is selected from a sensor reading, a temperature indication, or an actuator position.
19. The method of claim 17 , wherein each of the plurality of the change-of-value messages includes the change-of-value and a device indicator.
20. The method of claim 17 , wherein communicating the change-of-value update includes automatically communicating the change-of-value-update.
21. The method of claim 17 , wherein communicating the change-of-value update includes pushing the change-of-value-update to a communicatively coupled wireless device.
