The present invention relates to a fault diagnosis and intelligent warning method for monitoring a system device, including the following steps: step 1. establishing independent alarm analysis logic and independent recovery analysis logic based on a fault model of each alarm; step 2. controlling the alarm logic and the recovery logic to be mutually exclusively executed; the step 3. performing delay processing on an alarm event and a recovery event; and step 4. establishing a cascading relationship between alarm events generated after the delay processing: establishing an alarm cascading group based on a relationship between different alarm events, automatically determining, by using generation of an alarm event as a triggering condition, whether alarms in a same cascading group simultaneously exist within a time, and generating association information between alarm events. Compared with the prior art, the present invention has the following advantages: reducing a probability of occurrence of false alarms, reducing a quantity of invalid alarms, reducing storage space overheads, reducing system CPU consumption, reducing workloads of maintenance personnel, and the like.
