Describes the fault patterns of sensors and presents their mathematical functions. Based on the measured data of building energy management systems, uses the principal component analysis(PCA) method to establish a model and detect and diagnose four types of sensor faults in air conditioning monitoring systems. The results show that the PCA method has good performance in fault detection and diagnosis.
