Fault detection systems and methods for self-optimizing heating, ventilation, and air conditioning controls

Abstract:

A fault detection system for detecting a fault in a process system includes a first circuit configured to modify an input of the process system with a modifying signal. The fault detection system further includes a second circuit configured to receive an output from the process system and configured to determine whether the fault exists based on at least one of a reduction of a signal component and an unexpected transformation of the signal component, wherein the signal component corresponds to a function of the modifying signal.

Abstract(Chinese):

用于检测处理系统中的故障的故障检测系统包括被配置为利用修改信号修改处理系统的输入的第一电路。故障检测系统还包括第二电路，其被配置为接收来自过程系统的输出，并且被配置为基于信号分量的减小和信号分量的意外变换中的至少一个来确定故障是否存在，其中信号分量对应于修改信号的功能。
