Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
Embodiment 1
A kind of locomotive maintenance method based on expert knowledge library, including
S1, the foundation of knowledge base
Knowledge point is arranged according to fixed mapping ruler, establishes expert knowledge library；
The mapping ruler between knowledge in knowledge base point: R [s, d]=(s → d) is defined first；
Knowledge node s is the starting knowledge point under rule R, and d is the object knowledge point under rule R.
The main monitoring object of maintenance support system be rail line overall signal equipment, so s be ATP, ZC, CI,
ATS, semaphore, track section, meter shaft, transponder,.All monitorings line track traffic signals equipment set.
Each starting knowledge point can generate a knowledge according to regular R in s, so d is to be known according to what regular R was generated
The set of knowledge.
Important elements include: that (attribute: device type, location of the machine to be installed are set signalling arrangement during maintenance management
Standby service life, equipment have used the time), warning message (attribute: when alarm title, alarm level, alarm generate place, alarm
Between), processing method and work order executor.
Wherein work order executor is divided into specific breakdown maintenance personnel and expert group.
So R=[signalling arrangement+warning message+processing method+work order executor].
S2, the input of knowledge base
Existing maintenance knowledge is input to expert knowledge library according to fixation mapping ruler described in S1；
The knowledge inputted in knowledge base is divided to two kinds, and one is theoretical knowledges and Heuristics based on industry specialists, a kind of
It is direct field experience knowledge acquisition.
Knowledge acquisition process from industry specialists is as shown in Figure 3:
S211, by industry specialists about signalling arrangement breakdown maintenance knowledge entry；
S212 holds specialists meeting and is evaluated
S213, every knowledge typing knowledge base that evaluation is passed through；
Wherein, R principle is deferred to, work order executor fills in expert group.
Directly acquisition knowledge process is as shown in Figure 4 on site in source:
S221, maintenance personnel complete the maintenance of a faulty equipment；
S222, judges whether failure repairs success, if success, fills in work order receipt and is uploaded to maintenance support system,
A knowledge is generated according to rule, by the knowledge typing knowledge base of generation；If unsuccessful, fill in work order receipt and be uploaded to maintenance
Terminate after support system.
S3, the output of knowledge base
Information required for field maintenance person inputs according to regulation mapping ruler to knowledge base, knowledge base are advised according to mapping
Then result is exported to maintenance personnel；
The output of expert knowledge library is mainly to provide live same type or like device breakdown maintenance for maintenance personnel
It is recommended that so the output of expert knowledge library is one or more knowledge most like with failure described by current maintenance workers list.Dimension
Shield personnel can repair failure described in maintenance work order with reference to these knowledge.
The solution of most like knowledge:
It will be according to an output representation of knowledge are as follows:
[a* device type+location of the machine to be installed+b* equipment life+equipment has used time+c* alarm title+d* report to D=
Alert grade+alarm place+e* alarm generation time+f* work order executor]
The wherein value range of each weight are as follows: { a, b, c, d, e, f } ∈ [0,1], and meet a+b+c+d+e+f=1.
(each weight depending on project reality.Such as, when work order executes some artificial maintenance personnel, f=
0.05, when work order executes artificial expert group, f=0.15.)
Define degree of fitting: N=a+b+c+d+e+f.
After maintenance support system acquisition to a live fault alarm information, system software is asked according to degree of fitting formula
Solve preceding 10 (configurable) Heuristicses of degree of fitting N greater than P (e.g., P=0.5, can configure), as maintenance reference proposition with
Maintenance workers list sends jointly to maintenance personnel.
The maintenance work order process flow of maintenance support system based on expert knowledge library is as shown in Figure 5.
Maintenance personnel obtains after carrying out locomotive maintenance behind knowledge point, and result is arranged, is added in knowledge base.
