Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
First, an embodiment is explained. This section is an explanatory embodiment expanding on the claims so as to fully understand how the present invention is embodied by those skilled in the art.
The IETM fault data conversion and extraction method based on the product FMEA provided by the embodiment of the invention converts FMEA data into fault isolation data through the mapping relation between relational databases, and realizes data sharing between product guarantee information systems, as shown in figure 1.
As shown in fig. 2, the method for converting and extracting IETM fault data based on product FMEA according to the embodiment of the present invention includes:
s101, obtaining an FMEA report of a product, and converting FMEA data in the FMEA report into relational data;
s102, converting the relational data into an IETM fault isolation program XML; and visually displaying the XML of the fault isolation program.
The IETM fault data conversion and extraction method based on the product FMEA provided by the embodiment of the invention is as follows:
1, S1000D fault class data module
The biggest difference between the S1000D (based on the technical publication international specification of the public source database) and other standards is modularization, and the data module is the core of the S1000D standard. The data module organizes data in XML (Extensible Markup Language) format and constrains and verifies data in a corresponding schema. In the standard specification of S1000D 5.0.0 published in 6.2019, a data module is divided into 16 information types and a schema is defined for each type. Most of the data modules describe information in a flat-narrative form, and the generated IETM is often not very interactive. To enhance the interactivity of IETM troubleshooting, S1000D introduces a Data Module specifically for creating Fault content, namely a Fault Data Module (Fault Data Module).
The fault information is mainly used for describing information such as fault phenomena, fault diagnosis, fault positioning methods and the like of products. The schema of the fault class data module is of 5 types: fault reporting information (faultReporting: 4 types including isolatedFault, detetedfault, observedFault and correlatedFault) and fault isolation information (faulisolation). The fault report information can be used for the intelligent expert diagnosis and maintenance system to help accurately process the fault information, and the fault isolation information is used for detailing a specific fault isolation program and providing interactive troubleshooting guidance for a user. The invention mainly researches fault isolation information, uses a product FMEA (failure mode analysis and effects analysis) supportability analysis result to quickly create an IETM fault isolation data module, designs an interactive display style and assists maintenance personnel to quickly finish product fault diagnosis.
The fault isolation program < faultilsolation > element is used to specify the fault isolation method, and is described in detail in the < faultilationProducer > sub-element. The method mainly comprises sub-elements such as fault identification < fault >, fault description < faultDescr > and isolation program < isolationProcedure >, and is shown in fig. 3-4.
2. Realizing the conversion of FMEA data to IETM data
FMEA reports are written according to GJB/Z1391 and 2006 Fault modes, impact and hazard analysis guidelines, FMEA data are managed by adopting a relational mode, and IETM data modules in the S1000D standard are stored and exchanged by adopting an XML mode. Thus, the conversion of FMEA data to IETM fault isolation data modules may be viewed as a conversion of relational data to XML data.
The key point of realizing the data conversion from the relational data to the XML is to establish a mapping model between data. The mapping process of the method comprises two steps: first the FMEA relational data schema maps to the object schema, and second the object schema remaps to the XML schema, as shown in fig. 5.
The fields in the FMEA report may correspond to the data in the fault isolation Schema of the S1000D standard as follows:
TABLE 1FMEA report and Fault isolation Schema mapping
| FMEA report | Fault isolation Schema structure |
| Composition code + failure mode numbering | <fault faultCode＝””> |
| Name (R) | <detailedFaultDescr> |
| Function(s) | <detailedFaultDescr>/<systemIdent> |
| Failure mode | <faultDescr>/<desc> |
| Cause of failure | <isolationMainProcedure>/<isolationStep> |
| Influence of faults | <detailedFaultDescr>/<faultMessageIndication> |
| Maintenance project | <isolationProcedureEnd> |
3. Fault isolation program XML auto generation
After the data field in the FMEA report is mapped to the IETM database, the automatic creation of a fault isolation type data module is realized through the schema constraint of the IETM data management platform, and the automatically generated XML file can be previewed after the data module is detected in the IETM database.
4 fault isolation program data display style design
The fault isolation data module (XML file) only belongs to a pure text invention, only stores fault isolation information in a structured mode, in order to enhance readability and interactivity, stepping guidance of a fault isolation program and man-machine question-and-answer interactive reading are achieved through extensible presentation list transformation (XSLT) technology and WEB front-end technology (HTML5+ JavaScript + CSS), on the basis, an IEMT browser automatically constructs and generates a graphical troubleshooting flow chart according to a troubleshooting logic model designed in the fault isolation program and through analyzing text semantic information in the XML, product fault isolation information is clearly and comprehensively presented, maintenance personnel are assisted in rapidly carrying out fault location, and fault troubleshooting efficiency and accuracy are improved.
