Embodiment 1

[0037] Such as figure 1 , 2 As shown, a database-based 3D model management system includes a server and a client, the server includes a model database, 3D model files, and a WEB server, and the client includes a model requirement module, a model cache module, and a model configuration module, where:

[0038] The model database is used to store 3D model data, and uniformly encode and uniquely identify the 3D model;

[0039] The WEB server is used to obtain a model request, initiates the model request to the model database, and searches and searches in the model database, and finally the model database returns the corresponding model information to the WEB server;

[0040] The 3D model file is used to store 3D models of different versions in different hard disk locations by carrying out version identification of the 3D model;

[0041] The model configuration module is used to generate a model configuration file according to the model type and version information of the 3D mod...

Embodiment 2

[0060] Such as image 3 As shown, a database-based 3D model management method is divided into two parts: server and client. The server is deployed with Tomcat server, MySQL database, model files and model management software WPF. As a WEB server, Tomcat realizes the model data reception and response management of the client through the HTTP protocol. When receiving the model data request, it obtains the model data stored in the MySQL database through database query, and then obtains the model from the model file based on the model data, and then Return the model to the data requester. The model management software WPF realizes the registration and deregistration management of model files and model data, and realizes the model management and version management of the database. Generate configuration files in the form of xml, json, etc., which can be sent online or copied from the client.

[0061] The client user initiates a model data request through a browser such as IE, Fir...

Embodiment 3

[0063] According to the different requirements of different industrial software for models, different sub-model libraries are defined, including CAD model libraries for operation guidance, CG model libraries for 3D visualization operation guidance and 3D monitoring, etc., and each sub-model library is unified through the model database Manage and uniquely identify.

[0064] The model database does not contain 3D model data, and the 3D model files are stored in the hard disk. The 3D model data and the 3D model are relatively independent, and can realize CAD models made by software such as UG, Pro / E, Catia, SolidWorks, 3dmax, Maya, Blender, etc. The manufactured CG models and other types and standards of model storage improve the compatibility of 3D models in the model database. At the same time, the relatively independent storage method makes the upgrade and backup of the model library more efficient and flexible.

[0065] The 3D model files can be serialized in binary or deci...

Abstract

The invention discloses a database-based three-dimensional model management system, which comprises a server and a client, the server comprises a model database, a 3D model file and a WEB server, andthe client comprises a model demand module, a model cache module and a model configuration module; The three-dimensional model management method comprises the following steps: S1, generating a model configuration file, and storing the model configuration file to a client; S2, the client analyzes the model configuration file and sends a request to a WEB server of the server; S3, after the WEB server receives the model request, inquiring a model storage position and version data required by the request from a model database, obtaining a corresponding 3D model file from the 3D model file based onthe storage position and the version data of the model, and returning the 3D model file to the client through the WEB server; And S4, after receiving the 3D model file, the client stores the 3D modelfile into a model cache module for a user to use.

Description

technical field [0001] The invention relates to three-dimensional model management, in particular to a database-based three-dimensional model management system and method. Background technique [0002] At present, in fields with high manufacturing levels such as aerospace, aviation, and automobile industries, paperless workshop manufacturing has gradually become the mainstream workshop production trend. The design and manufacture of domestic small satellites has formed a set of full three-dimensional digital design and manufacturing methods, opened up the data flow from overall integrated design to final assembly products, and realized the paperless design and manufacturing process of small satellites. Aeroengine manufacturing is based on the MBD three-dimensional process system. According to the characteristics and requirements of the three-dimensional process, based on the collaborative platform of CAD and PLM, on the basis of CAX and IE, the process design system formed t...
