Production model identification.It should be noted that the production model recognition methods of production equipment provided in an embodiment of the present invention is simultaneously
It is not limitation with Fig. 2 and specific order below, it should be understood that in other embodiments, life provided in an embodiment of the present invention
The sequence for producing the part steps in the production model recognition methods of equipment can be exchanged with each other or therein according to actual needs
Part steps also can be omitted or delete.This method comprises the following steps:
Step S110, the current wave of acquisition input production equipment in the production equipment course of work.
In the present embodiment, electric current, which obtains, can integrate current sensor in equipment, for acquiring in production equipment work
The current wave of the production equipment is inputted during making.Wherein, the current wave of acquisition can be what section at preset timed intervals was acquired,
For example, the current wave of production equipment is inputted in acquisition one day as unit of day, alternatively, the current wave of acquisition is also possible in real time
Current data.It is understood that can also check the current wave received before the current wave of acquisition input production equipment
With the presence or absence of shortage of data.
Step S120 extracts multiple electric current wave bands in current wave according to the length of preset standard wave;Wherein, preset standard

Optionally, go out the number of the matching current wave band in current wave for accurate statistics, after step S123, this method
Can also include: obtain characteristic distance in minimal characteristic distance, and using minimal characteristic apart from corresponding electric current band group as
Electric current band group to be processed;The multiple target current wave bands not intersected between each other are selected from electric current band group to be processed.
Wherein, the step of multiple target current wave bands not intersected between each other are selected from electric current band group to be processed
Can specifically include: the length and minimal characteristic according to minimal characteristic apart from corresponding sliding window are apart from corresponding current wave
Section constructs unreasonable section, and ascending order traverses the corresponding characteristic distance of each electric current wave band to be processed in electric current band group to be processed,

Manage section.In turn, multiple target current wave bands not intersected between each other can be obtained in the element in ergodic sequence D.It needs
Illustrate, minimal characteristic is equally targeted electric current wave band apart from corresponding electric current wave band.
Step S124, if characteristic distance is less than preset threshold, Cutoff current wave band is and matched, preset standard wave
With electric current wave band.
For example, it is assumed that preset threshold be 0.7, then can be determined that electric current wave band of all characteristic distances less than 0.7 be with it is pre-
It is marked with the matched matching current wave band of quasi wave.
In the case where selecting the multiple target current wave bands not intersected between each other from electric current band group to be processed,
If the corresponding characteristic distance of target current wave band is less than preset threshold, determine that target current wave band is the matching current wave
Section.It is pre- by being less than in multiple target current wave bands i.e. after getting the multiple target current wave bands not intersected between each other
If the target current wave band of threshold value is determined as matching current wave band.
Step S130, if existing and the matched matching current wave band of preset standard wave in multiple electric current wave bands, it is determined that raw
Producing production model of the equipment within the matching current wave band corresponding period is default production model.
It in the present embodiment, can be first in order to determine whether a certain electric current wave band to be processed matches with preset standard wave
Calculate separately the feature of electric current wave band and preset standard wave to be processed, wherein the extraction of feature can be extract data mean value,
Variance, greater than mean value data number, the coefficient of 1 rank Fourier transformation and the inverse of first-order difference, then calculate wait locate
The distance between the feature of electric current wave band and preset standard wave (for example, mahalanobis distance, Euclidean distance) is managed, electric current to be processed is obtained
The characteristic distance of wave band and preset standard wave, finally judge this feature distance whether less than a threshold value, when less than a threshold value, then
Determine that the electric current wave band to be processed is matched with preset standard wave.
Step S140, calculates the number of matching current wave band, and determines matching current according to the number of matching current wave band
