Research on Remote Fault Diagnosis System based on PLC Controlling

摘要

Today's industrial control equipments on site become more automated, complex and continuous; in order to ensure normal, reliable and efficient operations of those equipments, and to ensure the safety of site personnel, condition monitoring and fault diagnosis must be carried out on those on-site equipments. In this paper, based on the studies of traditional fault diagnosis theories and modern fault diagnosis theories, it uses fault tree analysis (FTA) to establish the fault diagnosis model of tread line control system.
