Abstract

A building management system includes a communications bus, field devices connected to the communications bus, a cloud service including a machine learning engine; and a controller for an HVAC device. The controller communicates with the communications bus and the cloud service and is configured to transmit messages through the communications bus to the field devices, compile a list of connected field devices, receive sample data from the connected field devices, and transmit the sample data from the connected field devices to the cloud service. The controller is further configured to receive identifying characteristics for each of the connected field devices from the cloud service and to select a control logic file for the HVAC device based on the identifying characteristics.

Claims

1. A building management system comprising:

a communications bus;

a plurality of field devices connected to the communications bus;

a cloud service comprising a machine learning engine; and

a controller for an HVAC device, wherein the controller is communicably connected to the communications bus and the cloud service and is configured to;

transmit messages through the communications bus to the plurality of field devices connected to the communications bus;

compile a list of connected field devices from the plurality of field devices connected to the communications bus;

receive sample data from the connected field devices;

transmit the sample data from the connected field devices to the cloud service;

receive at least one identifying characteristic for each of the connected field devices from the cloud service, and

select a control logic file for the HVAC device based at least in part on the identifying characteristics.

2. The building management system of claim 1, wherein the plurality of field devices includes at least one temperature sensor, pressure sensor, or humidity sensor.

3. The building management system of claim 1, wherein sample data comprises at least one of temperature data, pressure data, and humidity data.

4. The building management system of claim 1, wherein the plurality of field devices communicate with the controller via the IEEE 1451.4 TEDS standard.

5. The building management system of claim 1, wherein an identifying characteristic comprises the field device location within the building management system.

6. The building management system of claim 1, wherein the HVAC device is at least one of a fan coil unit, a roof top unit, and an air handling unit.

7. The building management system of claim 1, wherein the cloud service comprises a machine learning engine.

8. The building management system of claim 1, wherein the controller is further configured to modulate an operation of at least one of a cooling coil and a heating coil in response to a message from the cloud service.

9. The building management system of claim 1, wherein the controller is further configured to modulate an operation of a fan in response to a message from the cloud service.

10. A method for controlling an HVAC device, the method comprising:

transmitting messages through a communications bus to a plurality of field devices connected to the communications bus;

compiling a list of connected field devices from the plurality of field devices connected to the communications bus;

receiving sample data from the connected field devices;

transmitting the sample data from the connected field devices to a cloud service;

receiving at least one identifying characteristic for each of the connected field devices from the cloud service, and

selecting a control logic file for the HVAC device based at least in part on the identifying characteristics of the connected field devices.

11. The method of claim 10, wherein the plurality of field devices includes at least one temperature sensor, pressure sensor, or humidity sensor.

12. The method of claim 10, wherein the sample data includes at least one of temperature data, pressure data, and humidity data.

13. The method of claim 10, wherein the plurality of field devices communicate with the controller via the IEEE 1451.4 TEDS standard.

14. The method of claim 10, wherein the HVAC device is at least one of a fan coil unit, a roof top unit, and an air handling unit.

15. The method of claim 10, wherein the cloud service comprises a machine learning engine.

16. The method of claim 10, wherein the method further comprises:

modulating an operation of at least one of a cooling coil and a heating coil; and

modulating an operation of a fan.
