First Claim
Patent Images
1. A computerized method for analyzing faults in a building management system, the method comprising:
- at a computer of the building management system, detecting a fault by evaluating data of the building management system using a system of rules;
determining a conditional probability for each of a plurality of possible fault causes of the detected fault;
determining a most likely fault cause by comparing the determined probabilities; and
electronically reporting the most likely fault cause.

Abstract
A controller for a building management system is configured to analyze faults in the building management system. The controller detects a fault in the building management system by evaluating data of building management system using a system of rules. The controller determines a conditional probability for each of a plurality of possible fault causes given the detected fault. The controller determines the most likely fault cause by comparing the determined probabilities and electronically reports the most likely fault cause.

11. A method for analyzing faults in a building management system, comprising:
-
at a supervisory controller of the building management system, detecting a fault by evaluating data of one or more remote devices in the building management system; in response to detecting the fault and by the supervisory controller, acquiring and storing new data from the building management system; and analyzing the detected fault using the new data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A supervisory controller for a building management system, comprising:
-
a communications interface; and a processing circuit configured to receive data from one or more remote devices in the building management system via the communications interface; wherein the processing circuit is configured to detect a fault by evaluating the received data; and wherein the processing circuit is configured to acquire and store new data from the building management system in response to detecting the fault.
