Abstract

A building management system includes a communications interface connected to HVAC devices, a device identifier configured to identify the HVAC devices, a fault detector configured to detect a fault condition in the identified devices, and a causal relationship template retriever configured to retrieve a fault causation template of system parameters specific to the fault condition. The building management system further includes a status requestor configured to retrieve operating data from the identified devices and a user interface generator. The user interface generator is configured to populate the system parameters of the fault causation template with the retrieved operating data and transmit a signal to display a user interface with the populated fault causation template on a display screen.

Claims (48)

1. A building management system (BMS) comprising:

a plurality of first HVAC devices operable to affect a physical state or condition;

a second HVAC device affected by the physical state or condition and having causal relationships with the plurality of first HVAC devices such that faulty operation of one or more of the plurality of first HVAC devices causes a detectable effect at the second HVAC device; and

a processing circuit comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

detecting a fault condition at the second HVAC device;

retrieving a fault causation template from a set of multiple different fault causation templates corresponding to multiple different fault conditions, the fault causation template corresponding to the fault condition and comprising a plurality of system parameters of the plurality of first HVAC devices that are potential causes of the fault condition;

retrieving operating data from the plurality of first HVAC devices;

populating the plurality of system parameters of the fault causation template with the operating data retrieved from the plurality of first HVAC devices; and

transmitting a signal to display a user interface comprising the fault causation template populated with the operating data on a display screen.

2. The building management system of claim 1 , the operations further comprising determining an operating state of at least one of the plurality of HVAC devices or the second HVAC device.

3. The building management system of claim 2 , wherein the operating state is at least one of an alarm state, a cooling state, a heating state, a commissioning state, and a standby state.

4. The building management system of claim 1 , wherein the display screen is a chiller device display screen.

5. The building management system of claim 1 , wherein the display screen is a user computing device display screen.

6. The building management system of claim 1 , wherein the plurality of HVAC devices and the second HVAC device include at least one of an air handling unit, an economizer-type air handling unit, a variable air volume unit, a rooftop unit, a damper, an actuator, a fan, a pump, a valve, and a thermostat.

7. The building management system of claim 1 , wherein the plurality of system parameters of the one or more of the first HVAC devices that are potential causes of the fault condition include at least one of a valve position, a damper position, a pump status, an actuator status, an air flow rate, a water supply temperature, an outdoor air temperature, and a fan percent command.

8. The building management system of claim 1 , wherein the user interface comprising the fault causation template includes a hyperlink that opens a user interface page configured to modify at least one system parameter of the system parameters.

9. The building management system of claim 1 , wherein the user interface comprising the fault causation template includes a hyperlink that opens a user interface page configured to display historical data associated with at least one system parameter of the system parameters.

10. A method of creating a data driven user interface for a building management system comprising:

operating a plurality of HVAC devices to affect a physical state or condition;

detecting a fault condition at a second HVAC device affected by the physical state or condition and having causal relationships with the plurality of HVAC devices such that faulty operation of one or more of the plurality of HVAC devices causes a detectable effect at the second HVAC device;

retrieving a fault causation template from a set of multiple different fault causation templates corresponding to multiple different fault conditions, the fault causation template corresponding to the fault condition and comprising a plurality of system parameters of the plurality of HVAC devices that are potential causes of the fault condition;

retrieving operating data from the plurality of HVAC devices;

populating the plurality of system parameters of the fault causation template with the operating data retrieved from the plurality of HVAC devices;

and transmitting a signal to display a user interface comprising the fault causation template populated with the operating data on a display screen.

11. The method of claim 10 , wherein the method further includes:

determining, by a state identifier of the building management system, an operating state of at least one of the plurality of HVAC devices.

12. The method of claim 11 , wherein the operating state is at least one of an alarm state, a cooling state, a heating state, a commissioning state, and a standby state.

13. The method of claim 10 , wherein the display screen is a chiller device display screen.

14. The method of claim 10 , wherein the display screen is a user computing device display screen.

15. The method of claim 10 , wherein the plurality of HVAC devices and the second HVAC device include at least one of an air handling unit, an economizer-type air handling unit, a variable air volume unit, a rooftop unit, a damper, an actuator, a fan, a pump, a valve, and a thermostat.
