When slot oil pressure data are strong incidence relation or the extremely important non-control, when the non-control does not fall within corresponding control
Pressure oil groove oil pressure data invalid is directly thought in the limit section of data.Above-mentioned several situations need to determine according to the actual situation
It is fixed.
It more preferably, in the present embodiment, further include to new collected process data in data correlation processing step S2
Judged:
It is corresponded to when the numerical value of some key non-control and/or multiple non-control falls into pressure oil groove oil pressure data
When the limit section of value, then it is assumed that meet related relevance rule between pressure oil groove oil pressure data non-control associated with it
Rule, then judge that pressure oil groove oil pressure data are effective, and the control foundation as corresponding oil gear pressure oil groove oil pressure；
Judgement does not fall between the non-control pressure oil groove oil pressure data associated with it in limit section and does not meet simultaneously
Related relevance rule, and it is further contemplated that the non-control is invalid data, it reports an error to non-control, and do not made
For the diagnosis basis of oil gear pressure oil groove oil pressure.
With being mentioned in above-mentioned data correlation processing step S2 on the contrary, whether the step is for judging pressure oil groove oil pressure data
For normal data, specifically, if most of non-control or some crucial non-control fall into the pressure oil groove
The limit section of oil pressure data, then it is assumed that pressure oil groove oil pressure data are normal data.
At this point, corresponding to this kind of situation, it is preferable that in the present embodiment, for some non-control and/or multiple non-
The value of control data falls into the case where limit section of corresponding control data, judgement do not fall within the non-control in limit section with
Related relevance rule is not met between associated pressure oil groove oil pressure data, and is further contemplated that the non-control is invalid
Data report an error to non-control and not as the control foundation of diagnosis oil gear pressure oil groove oil pressure.
And then judge to obtain that the element of the non-control or relevant device are abnormal, and take corresponding operating.I.e. at this time not
The non-control for falling into deviation profile region can be abnormal data under normal conditions, and artificial/machine is needed accordingly to be judged
Operation.
It is preferred that in the present embodiment, when some key non-control and/or multiple non-control
When numerical value falls into pressure oil groove oil pressure data and corresponds to the limit section of value, and there are the numerical value of one and/or several non-control
When not falling within pressure oil groove oil pressure data and corresponding to the limit section of value, diagnoses it and be not inconsistent between associated pressure oil groove oil pressure data
The related relevance rule of conjunction, and according to the situation that reports an error of non-control, shift to an earlier date according to pressure oil groove oil pressure data and/or lags
Mode carries out PREDICTIVE CONTROL to oil gear pressure oil groove oil pressure.
Specifically, when limit section due to being in pressure oil groove oil pressure data in most of non-control, non-controlling number
According to the control foundation not as oil gear, but its non-control for going beyond the limit of process section can also illustrate related content
Go wrong (collection terminal itself goes wrong or data acquisition goes wrong), therefore can be reported an error at this time according to non-control
