System, method and apparatus for building operations management
A system, method and apparatus for integrated building operations management. Nodes in the sensor network can be configured to interface with a building control system to exchange sensor-related information.
1. A device at a monitored location, comprising
a transceiver that receives a configuration update packet, the configuration update packet including configuration information that is delivered by a host system that is remote from the monitored location;
a wired communication interface configured to connect the device to a BACnet device that supports a BACnet data communication protocol; and
a controller that periodically initiates a formation of a request to obtain sensor data from the BACnet device using the configuration information, and delivers the request to the BACnet device via the wired communication interface.
2. The device of claim 1 , wherein the transceiver is a wireless transceiver.
3. The device of claim 2 , wherein the wireless transceiver is based on IEEE 802.15.4.
4. The device of claim 1 , wherein the configuration update packet is received from a gateway device.
5. The device of claim 4 , wherein the gateway device is installed at the monitored location.
6. The device of claim 4 , wherein the device is configured to receive, from the gateway device, sensor based information that has been processed by the host system and to present the sensor based information to the BACnet device via the BACnet data communication protocol.
7. The device of claim 6 , wherein the sensor based information is a control signal configured to change a state of a device at the monitored location.
8. The device of claim 1 , wherein the device is configured to receive baud rate information and parity information, the baud rate information and the parity information enabling the device to form a message for communication using the BACnet data communication protocol.
9. The device of claim 1 , wherein the BACnet device is part of a building control system that controls a Heating, Ventilation and Air Conditioning (HVAC) system.
10. A method, comprising:
receiving, by a transceiver in a device in a building, a configuration update packet including configuration information that is delivered by a host system that is remote from the monitored location, wherein the device further includes a wired communication interface configured to connect the device to a BACnet device that supports a BACnet data communication protocol;
forming periodically, by the device, a request to obtain sensor data from the BACnet device using the configuration information; and
delivering, by the device, the request to the BACnet device via the wired communication interface.
11. The method of claim 10 , wherein the transceiver is a wireless transceiver.
12. The method of claim 11 , wherein the wireless transceiver is based on IEEE 802.15.4.
13. The method of claim 10 , wherein the receiving comprises receiving from a gateway device.
14. The method of claim 13 , wherein the gateway device is installed at the monitored location.
15. The method of claim 13 , further comprising receiving, by the device, sensor based information that has been processed by the host system and to present the sensor based information to the BACnet device via the BACnet data communication protocol.
16. The method of claim 15 , wherein the sensor based information is a control signal configured to change a state of a device at the monitored location.
17. The method of claim 10 , wherein the receiving comprises receiving baud rate information and parity information, the baud rate information and the parity information enabling the device to form a message for communication using the BACnet data communication protocol.
18. The method of claim 10 , wherein the BACnet device is part of a building control system that controls a Heating, Ventilation and Air Conditioning (HVAC) system.
