But along with the development of computer software technology, new PDM system no longer supports early stage, non-mainstream software, results in hand cramps for the informatization of enterprise.The problem that enterprise faces is exactly to spend huge sums again to purchase new software, also needs former figure shelves by translation interface or the manual again software format that transfers system's support to.If former software does not provide general-purpose interface, also need special research and development translation interface could realize the conversion of drawing and integrated.

Three, summary of the invention

Technical matters to be solved by this invention provides a kind of integrated approach of product data management system.This method has overcome the limitation that the preceding PDM integrated application system of H exists, and can realize that the encapsulation of the existing CAD software of present most commercialization PDM software and enterprise is integrated.

Technical scheme of the present invention: be a kind of integrated approach of product data management system, it is characterized in that accompanying method comprises the steps:

1) carry out the engineering drawing design in CAD software, design result saves as the CAD document;

2) in the CAD environment, generate print file, or generate document printing by batch program;

3) in the PDM environment, create document object, with reference documents or the annex of document printing as the CAD document, from the CAD document, extract document properties automatically by keyboard input document properties (as management information such as coding, title, department's types) or use document properties template, and deposit it in PDM database;

4) in the PDM environment, create the parts object, with the description document of CAD document as the parts object, by the keyboard input part attribute (as coding, title, material, the figure number of parts, and deposit it in PDM database management information such as categorical attribute, technical requirement) or use the parts attribute templates from the CAD document, to extract the parts attribute automatically;

5) examine in the label flow process in the engineering of PDM, search above-mentioned parts object, open related description document (CAD document), utilize the built-in browser of PDM system in reference documents or annex (document printing), to go over, finish the relevant design business activity of figure shelves.

The present invention compares with existing integrated approach, has following beneficial effect:

1. formulate the environmental restraint that PDM system integration scheme is not subjected to CAD software and operation thereof, need not change CAD software in order to realize integrated;

2. do not need to develop special data exchange interface, more be not subjected to the restriction of exchanges data standard;

3. solved the problem of going over based on the engineering drawing in the operation flow of WEB technology, needn't be in operation flow each first file in download, open CAD software again and browse;

4. all can print drawing as required voluntarily at any service link, or control, and needn't rely on CAD software or print driver prints by drawing print management system (flow process);

5. this method helps improving the inheritance of Enterprise Resource, accelerates the construction process of IT application in enterprises.

Four, embodiment

Be example with the WINDCHILL integrated application system below, be specifically described as follows:

For ease of narration, provide the several concept explanations among the PDM that the present invention relates to here:

In the WINDCHILL system, the unified parts object that adopts of the assembly in the engineering design, parts, conjunction and part manages.By setting up the use (Use) between the parts object and being used (Usedby) relation structure product tree.

Document object among the WINDCHILL is not equal to all kinds of e-files under the operating system, but the notion of using in the service management.For ease of understanding, can be considered as a folder bag to document object, some different but vital documents (master file and a plurality of annex) of close ties of wherein can packing into.On the folder bag, write down the attribute (comprising information such as numbering, title, founder, key word) of document.The document is divided into two classes:

Common document---be used for the reference of parts object or description document.Refer generally to utilize the various files of all kinds of text-processing softwares (as Word, Excel etc.) establishment.

The CAD document---be used for the description of parts object.Refer to drawing/model file specially with the CAD software creation of system's support.

Need to prove that ICEM DDN V2.0 software is for operating in the CAD software in the IRIX operating system in early days, the WINDCHILL system does not support this software, though can will use the CAD engineering drawing of this software drafting according to common document and parts object association, but in the product design flow process, can't realize going over function, and open the restriction that also is subjected to the CAD software runtime environment after downloading.

Below examine to sign flow process with concrete engineering be example, the integrated detailed process of interactive mode realization be described:

1) carry out the engineering drawing design in ICEM DDN software, design result saves as the CAD document.

2) utilize the printing function of ICEM DDN software to generate document printing, or use batch program to generate document printing automatically.

3) create document object in the WINDCHILL system, operation steps is as follows:

(1) clicks the establishment documents button, enter the establishment Document Interface;

(2) specifying above-mentioned CAD document is the main contents file;

(3) attribute (coding, title, type, title, department, marshalling etc.) of input document object;

(4) specify above-mentioned document printing as reference document or annex;

(5) preserve document object.

4) create parts object and related with document object in the WINDCHILL system, operation steps is as follows:

(1) opens the product information browser, enter the establishment component interface;

(2) specify the document object of above-mentioned establishment for describing document;

(3) attribute of specified parts object (coding, title, material, categorical attribute, marshalling, workflow etc.);

(4) as required, set up the structure (but selection operation) of parts object;

(5) preserve the parts object.

5) start engineering and examine the label operation flow, role in the flow process (proof-reader, process structure examiner, standardization examiner, auditor and ratifier) goes over this parts object according to professional responsibility, if this parts object certain link is on stream rejected, the designer can check and go over, and according to going over suggestion it is made amendment.With proof-reader is example, and the concrete operations step is as follows:

(1) enters in proof-reader's worksheet, open the check and correction task relevant with these parts;

(2) attribute of inspection part object;

(3) the CAD document of click parts object association;
