Describes the type of sensor fault and gives its fault function. The principal component analysis method is used to model the measurement data of building energy management and control system and to detect and diagnose the four types of sensor faults in the air conditioning detection system. The results show that the principal component analysis has good fault detection and fault diagnosis capabilities.
