Embodiment 1

[0045] This embodiment provides a method for the CAE database system to obtain CAD data, such as figure 1 As shown, steps S101, S102, S103 and S104 are included. Each step is described in detail below.

[0046] Step S101: According to the CAD data to be obtained by the CAE database system, obtain the BOM information of the CAD data from the PDM database system.

[0047] The process of obtaining the BOM information of the CAD data may be that the PDM database system pushes the BOM information to the CAE database system, or may directly retrieve and obtain the BOM information of the CAD data from the PDM database system.

[0048] Specifically, the BOM information may include a head node ID and a version number.

[0049] Step S102: According to the BOM information, search whether the BOM exists in the CAE database system.

[0050] Specifically, according to the BOM information pushed by the PDM database system or directly retrieved and obtained from the PDM database system, it...

Embodiment 2

[0065] Corresponding to Embodiment 1, this embodiment provides a device for acquiring CAD data by a CAE database system, such as figure 2 As shown, it includes an acquisition module 201 , a retrieval module 202 , a creation module 203 and a writing module 204 . Each module is introduced in detail below.

[0066] The acquiring module 201 is configured to acquire the BOM information of the CAD data from the PDM database system according to the CAD data required to be acquired by the CAE database system.

[0067] The process of acquiring the BOM information of the CAD data by the acquiring module 201 may be that the PDM database system pushes the BOM information to the CAE database system, or may directly retrieve and acquire the BOM information of the CAD data from the PDM database system.

[0068] Specifically, the BOM information may include a head node ID and a version number.

[0069] The retrieval module 202 is configured to retrieve whether the BOM exists in the CAE dat...

Abstract

The present invention provides a method and device for obtaining CAD data by a CAE database system, the method comprising: obtaining the information of the BOM of the CAD data from the PDM database system according to the CAD data to be obtained by the CAE database system; BOM information, search whether the BOM exists in the CAE database system; when the BOM is not found in the CAE database system, create a BOM in the CAE database system, and write the CAD data into the created The specified location of the BOM; when the BOM is found in the CAE database system, it is judged whether the CAD data exists in the specified location of the BOM, and if the CAD data does not exist in the specified location of the BOM, the The CAD data is written into the specified location of the BOM. The method and device for obtaining CAD data by a CAE database system provided by the present invention can realize that the CAE database system obtains and effectively stores required CAD data from a PDM database system.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and a device for obtaining computer-aided design CAD data by a computer-aided engineering CAE database system. Background technique [0002] At present, the CAE database system is in the process of development, while the product data management PDM database system is relatively mature, and CAD data is generally managed in the PDM database system. There are two main ways for CAE database system to manage data, one is to manage CAE data directly in PDM database system, and the other is to manage through an independent CAE database system. For the first method, since CAD data and CAE data are managed in the same system, the data can be managed in the same way, and there is no problem of version traceability between CAD data and CAE data; for the second method of data management, in When considering the version traceability of CAD data and CAE data, it is necessary to ass...
