Detailed Description
The present application realizes standard specification digitization by establishing a standard specification data model, so that a computer can directly use the standard specification to perform various operations such as selection, construction, optimization and the like on a product, and the present invention is further described in detail with reference to fig. 8 and a specific implementation method.
A standard specification digital processing method facing equipment technical indexes specifically comprises the following steps:
Analyzing the product standard type and index composition characteristics commonly used by the product, and establishing a general technical index data model of the equipment by using an XML editing tool. The general technical index data model is used as a master file for index digital processing, defines information composition, attribute relation, necessity, constraint and value range of equipment technical indexes, and mainly comprises the following steps: the system comprises a standard number, a product name, a product to which the standard number belongs, an index name, an index to which the index belongs, an index chapter number, an index technical requirement, an index numerical value, an index metering unit, a test method chapter number, an identification test method, a quality consistency test method, a first article inspection method, experience teaching and training and the like.
As shown in fig. 1, a SCHEMA file is created by using a general XML editing tool (such as XMLSpy, xmlquiire, etc.), and a W3C XML SCHEMA is selected in fig. 1 to create the SCHEMA file, which may be named as "general technical indicator model. XSD", and the SCHEMA file is a specific implementation of the general technical indicator data model.
The general technical index data model in the SCHEMA file may specifically include standard information and product information, where the standard information includes a standard number and a standard name, the product information includes a product name, a product to which the standard information belongs and a technical index, and the technical index includes an index name, an index to which the standard information belongs, an index chapter number, an index technical requirement, an index value, an index measurement unit, a test method chapter number, an identification test method, a quality consistency test method, a first article inspection method, and an experience training. Fig. 2 is a block diagram of the universal specification data model, and those skilled in the art can set the elements in the universal specification data model according to actual needs.
The specific content in the SCHEMA file is determined according to the elements in the generic technical indicator data model, and the SCHEMA file functions to define a legal component group of an XML document, such as: elements that may appear in a document, attributes that may appear in a document, which elements are sub-elements, the order of sub-elements, the number of sub-elements, etc. Fig. 3 is a SCHEMA file created from the structure diagram of the generic technical indicator data model shown in fig. 2.
Creating a new XML document for each standard specification file based on the general technical index data model constructed in the step 1; extracting technical contents in aspects of product functions, performances, interfaces, tests, packaging, transportation and the like in the corresponding standard specification file one by one and one by one according to element composition defined by the universal technical index data model, and sequentially inputting the technical contents into the corresponding XML tags to form an instantiated XML document; a standard may contain a plurality of products, and a product may contain a plurality of index information.
Firstly, a general XML document is created based on the general technical index data model constructed in the step 1 by using a general XML editing tool. As shown in FIG. 4, in this embodiment, Altova XMLSpy is used to create an XML instantiated document based on the Universal technical indicator model XSD file.
And then, extracting the technical contents related to the indexes in the standard specification one by one and one by one, and respectively inputting the technical contents into the corresponding XML tags. As shown in fig. 5, taking the extraction of information in the standard "general specification for aircraft wheels and brake devices" as an example, the following information is extracted:
standard information:
standard number: GJB 1184A-2010
Standard name: general specification of aircraft wheel and brake device
Product information:
the product name is as follows: airplane wheel
The product is a lifting device
The technical indexes are as follows:
index name: air tightness of tubeless airplane wheel
The indexes are as follows: air tightness
The number of the index seal bar: 3.2.2.1
The technical requirements of the indexes are that the airplane wheel rolls for 40km under rated static load, and the pressure drop is not more than 0.03 MPa.
Index value: 0.03
The index measurement unit is as follows: mpa (Mpa)
Test methods chapter number: 4.5.2
The identification test method comprises the following steps: the wheel provided with the inner tube vertically rolls for 40km under rated load and inflation pressure, and the pressure drop meets the requirement of c) in 3.2.2.1. The rolling mileage of the experiment can be accumulated in the rolling experiment mileage.
Quality consistency test method: NULL
The first piece inspection method comprises the following steps: NULL
Experience training: NULL
Step 3, XML document verification
After the standard index data is extracted, automatically checking the instantiated XML document based on the rule defined by the data model so as to verify whether the XML document has effective data and good format. The SCHEMA data model may verify: structure of elements and attributes; the order of the elements; data values of elements and attributes, according to range, enumeration and style matching; uniqueness of values in the examples, etc. If the verification fails, the instantiated XML document needs to be re-modified according to the rules of the SCHEMA data model until the document verification is completed. In the embodiment, the instantiated XML document is automatically checked by using the rule defined by the XSD, so as to form a final XML document corresponding to the standard specification.
After the standard index data is extracted and the instantiated XML document is formed, the document can be verified by using the format checking function and the data verification function of the Altova XMLSpy tool. And after the verification is passed, a final XML document with good format and effective data is formed. The following is a validated XML document for "general aviation wheel and brake device specifications":
