Characteristic with sample in this classification.The method is it is determined that only according to one or several closest samples on categorised decision
Classification determining the classification belonging to sample to be allocated.KNN methods only have in classification decision-making with minimal amount of adjacent sample
Close.Because KNN methods are mainly by neighbouring sample limited around, rather than by differentiating the method for class field determining generic
, for the more sample set to be allocated of the intersection or overlap of class field, KNN methods are more suitable for compared with additive method.
In the present embodiment, the server 300 takes out predetermined number from being stored in the sample set of data base 350
The sample for reference vector of (such as, T), and by the sample for reference of the predetermined number (such as, T) it is vectorial and it is described vibrate to
Amount (V) is brought into be analyzed one by one in predefined diversity judgement function and obtains analysis result.The basis of the server 300
The analysis result of the diversity judgement function be met with the default similarity of the moments of vibration (V) require it is several (such as,
N) sample vector.The particular number (T) of the predetermined number that the sample for reference vector is chosen can set according to actual test situation.
Citing is described in detail to said process below.
Pre-defined one phase for being used to judge moments of vibration (V) and the sample for reference vector of predetermined number (such as, N number of)
Like the diversity judgement function of degree.For example：| A-B |, i.e., for certain moments of vibration Va and certain sample vector Vb to be judged, use
The distance between two vectors are judged, i.e. the vector length of the difference of two vectors is judging two vectors whether phase mutual connection
Closely.When the vector length of the difference of two vectors presets judgment value less than one, show that two vectors meet default similarity and require.
Wherein, the default judgment value can set according to actual test situation.Accordingly, for certain moments of vibration (V), can pass through and pre-
If the sample for reference vector of quantity (T) enters one by one row distance calculating, find meet N number of sample that default similarity requires to
Amount.Wherein, the big I of N values sets according to actual test situation.
Step S150, server 300 judges the vibrational state of the plant equipment according to the vibrating data analysis result,
And shown the vibrational state of the plant equipment.
In the present embodiment, the vibrational state includes normal condition and abnormality, and it is not right that the abnormality includes
Middle state, unbalanced state, state of wear, loosening state, malfunction etc..Wherein, the respective state letter of every kind of vibrational state
Breath is pre-stored in the vibrational state set of data base 350 (such as, S), and every kind of vibrational state is in the vibrational state collection
Closing in (S) has corresponding identifier, for example：Normal condition can be identified with S1 marks, condition of misalignment with S2, Bearing Grinding
Available S3 marks are damaged, by that analogy.
In the present embodiment, the server 300 is right based on the vibrational state set (S) and mapping set (such as, F)
Meeting several (N) sample vectors required with the default similarity of the moments of vibration (V) carries out matching operation, obtains described several
(N) sample vector each distinguishes corresponding vibrational state.The server 300 is analyzed several (N) sample vectors and is each divided
Not corresponding vibrational state obtains the optimum vibrational state of a matching rate as the vibrational state of the plant equipment.The clothes
The vibrational state that business device 300 can map the corresponding plant equipment by the moments of vibration (V) and with it is saved in the clothes
In the data base 350 of business device 300, with continuous exptended sample set.The server 300 is by the vibrational state of the plant equipment
Presentation of information to staff, to inform whether plant equipment described in staff needs repairing.
In the present embodiment, the optimum vibrational state of the matching rate refers to the N number of of the default similarity requirement of the satisfaction
Certain most vibrational state of correspondence is mapped in sample vector, the matching rate can set according to actual test.Such as, matching rate
80% is set to, is being met in 10 sample vectors that default similarity is required, there are 8 to be normal condition, then be can determine that described
Moments of vibration (V) is normal condition, i.e., the corresponding plant equipment of described moments of vibration (V) is in normal condition.
