Abstract

The invention belongs to the technical field of digital manufacturing of aircrafts, and relates to a method for verifying consistency of a product structure and a model derived from a VPM. Firstly, analyzing the issued model file through the secondary development of CATIA, reading the product structure in CATProduct, and then calculating the unique code of each CATPart; deploying a remote call service on a database server of the VPM, and acquiring structural information and attributes of the product by inquiring a database table of the VPM; the local program calls the service by taking the drawing number version as a parameter, acquires the structure and attribute information of the product, and simultaneously acquires the position of the CATPart file corresponding to the part and the version in a Vault warehouse; calling a remote service program deployed in a Vault warehouse to obtain the position of the electronic warehouse where the CATPart is located, finding out the digital-analog file, calculating a unique code, and returning the result; and finally, comparing the unique codes of the local product structure and the model file with the returned result of the program call, and judging the difference between the unique codes to determine the consistency of the issued data and the data in the VPM.

Description

Method for verifying consistency of product structure and model derived from VPM

Technical Field

The invention relates to a consistency verification method for a VPM derived product structure and model, belonging to the technical field of digital manufacturing of aircrafts.

Background

The current aircraft design phase is typically model design with CATIA and collaborative design management using VPM. After the design is completed, CATProduct files are exported from the VPM, and CATParts are organized using CATProducts to form a product structure, which is then issued. However, due to errors of the export procedure or problems of some types such as transmission stage, the model file opened in the field can appear in the phenomenon that the VPM is inconsistent, so that the model cannot guide production correctly. There is no way to verify that the received product structure and model remain consistent with the design end.

Disclosure of Invention

The invention divides the consistency of verification and distribution data into two aspects, namely, the consistency of the structure and the attribute of the product is verified, and the consistency of the model is verified.

The technical scheme of the invention is as follows:

a method for verifying the consistency of a product structure and a model derived from a VPM comprises the following steps:

firstly, a data packet file is acquired, a model file issued is analyzed through secondary development of CATIA, the product structure in CATProduct, namely the father-son relationship among instance numbers, drawing numbers, versions and instances, and the CATPart file associated with each drawing number and version are read, and then the unique code of each CATPart is calculated. And recorded in the program memory. And deploying a remote call service on a database server of the VPM, and acquiring structural information and attributes of the product by querying a database table of the VPM. The local program calls the service by taking the drawing number version as a parameter, acquires the structure and attribute information of the product, and simultaneously acquires the position of the CATPart file corresponding to the part and the version in the Vault warehouse. And then calling the position of the electronic warehouse where the CATPart obtained in the previous step is located, finding out the digital-analog file, calculating a unique code, and returning the result. And finally, comparing the unique codes of the local product structure and the model file with the returned result of the program call, and judging the difference between the unique codes to determine the consistency of the issued data and the data in the VPM.

The invention has the beneficial effects that: the invention provides a method for rapidly checking whether the received CATIA product structure, model file and design end VPM data are consistent. Compared with manual detection, the method is quicker and more accurate, and the accuracy of production basis is greatly improved.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the drawings.

A method for verifying the consistency of a product structure and a model derived by a VPM (virtual private Mobile) requires the deployment of two services, the information acquisition and verification in four steps:

the first step, through the model file of the analysis release of the secondary development of CATIA, read the product structure in CATProduct, namely the father-son relation among example number, figure number, version, example, and CATPart file that each figure number, version are correlated with, calculate the unique code of each CATPart again. The information of the issued file is obtained through the mode and recorded in the program memory.

And secondly, deploying a remote call service on a database server of the VPM, and acquiring the structure information and the attribute of the product by inquiring three tables of the VPM database vpmassemblyrelation, vpmpartversion, vpmpartmaster and the version information of the product. The first step program uses the drawing number version of the product as a parameter to call the service, and obtains the structure and attribute information of the product. Meanwhile, the service can obtain the storage position of the CATPart file corresponding to the drawing number and version in Valut by querying the VPM database table vpmpartversion, vpmpartmaster, vpmtpproperty, vpmtprelationctoa database table. The first step program calls the service by taking the figure version of the part as a parameter, and the position of the CATPart file corresponding to the part and the version in the Vault warehouse can be obtained.

Thirdly, deploying a remote calling program in a Vault warehouse, finding out the digital-analog file by using the position of the electronic warehouse where the CATPart obtained in the second step is located, calculating a unique code, and returning the result.

And fourthly, comparing the unique codes of the product structure and the attribute information and the CATPart obtained in the first step with the information obtained in the second step and the third step, and judging the consistency of the product structure and the model.

In addition, if the product structure is found to be a black box in the fourth verification process, the second step and the third step are repeated to calculate the unique code of the CATProduct file of the black box, and then the comparison verification is carried out.
