Claim 3:
4. The method according to claim 1, wherein setting the diagnostic label as the identification framework comprises:
dividing data to be tested first into two types of diagnosis of healthy and unhealthy in a first stage of diagnosis, so that the identification framework is Θ={healthy, unhealthy}, or dividing the data to be tested into different health levels,
wherein when the diagnosis result is that the data to be tested is in an unhealthy state and a fault type has to be further detected, at this time, a second stage of diagnosis is entered, where the fault type is Fi (i=1, 2, . . . ), and the identification framework is set to Θ={F1, F2, . . . , Fi, . . . },
wherein when the diagnosis result is that the data to be tested is in the unhealthy state and a fault location has to be further detected, at this time, a third stage of diagnosis is entered, where the fault location is Lj (j=1, 2, . . . ), and the identification framework is set to Θ={L1, L2, . . . , Lj, . . . },
wherein to ensure a unified description, all elements in the identification framework are marked as Θ={H1, H2, . . . , Hl, . . . , HN}, where l represents number of a subset in the identification framework, and N represents number of all subsets in the identification framework.
