Abstract

Prognostics and health management (PHM) is a highlight of current research in modern industrial equipment fields. Aiming at the requirement of verification of PHM system’s fault diagnosis capability, a fault injection device is designed and it consists of the digital control unit, fault injection unit, failure mode switching unit, channel switch unit, a status indication unit, data acquisition unit, communication unit and control software unit. The procedures of fault injection experiment are expounded in this chapter. Then a control computer system is applied to a fault injection experiment based on the probe-type fault injector, and the capabilities of fault diagnosis of PHM system are verified. Experiment results show that the probe-type fault injector can be effectively used to verify the PHM fault diagnosis capability of electronic systems and it is non-destructive and easy for operation.
