One kind of equipment fault diagnosis method based on double data path

The present invention discloses a kind of fault diagnosis method based equipment dual data paths, comprising collecting equipment operating parameters, the operating parameters including type of equipment, the equipment ID, the acquisition time, operating parameters of the type and operating parameter value corresponding to; receiving equipment operating parameters , and in accordance with the type of equipment operating parameters statistical analysis, the induced outage probability of the knowledge table; analyzing equipment operating parameters for any irregularities data center according to the stored parameters abnormal range knowledge table; if present, the abnormality alert, while the data center storage induced outage probability of the knowledge table determined operating parameters and the probability of fault type, fault induced and alert.
