Problems solved by technology
[0005] The disadvantages of this method mainly include: the exchanged data packets do not contain BOM structure information, data update, and exchange attribute information. It is necessary to manually organize and update the product structure tree, with low efficiency and high error rate, and it is impossible to obtain and judge the update status information of the data. , resulting in repeated sending of frozen data that has been exchanged and unupdated data that does not need to be exchanged, and even can only achieve full data exchange. The data exchange volume is huge and the efficiency is low.

Embodiment 1
[0040] Taking the transnational multi-party collaborative development engineering data exchange system of a certain research institute as an example, in the process of developing a certain aircraft model, a certain research institute needs to regularly exchange model development data with a foreign research and development institution to meet the requirements of collaborative development, and develop according to the method of the present invention A data exchange system that can meet the needs of collaborative development of large-scale products has been established. This system has been deployed in various collaborative development units. Now take this scenario as an example to illustrate the implementation process of the method. For the implementation flow chart, please refer to figure 1 :
[0041] 1) During the development process of this aircraft model, a consistent Dassault VPM1.6 product data management system was adopted to manage product data. Under the environment of ...

The invention discloses a collaborative data exchange method, belongs to the technical field of multi-sited collaborative design of large-scale products and relates to transnational multi-party digital design collaborative data exchange application of large-scale products such as a helicopter. The collaborative data exchange method is characterized by comprising the following steps of utilizing a product data management system and organizing and expressing a data structure and a design file of a product by using pattern data sets as the center; extracting historical data exchange record variable values of the pattern data sets in a database of the product data management system; executing a discriminator 1; filtering and deleting the frozen and exchanged pattern data sets; extracting digital sequence variable values of the pattern data sets; executing a discriminator 2; filtering and deleting the non-updated pattern data sets. The collaborative data exchange method eliminates the defect that in a conventional file-based data exchange method, the data structure of the product needs to be maintained in a manual manner; data increment exchange is implemented; data exchange efficiency is promoted; consistency of data among collaborative enterprises is ensured.
Description
technical field [0001] The invention belongs to the technical field of collaborative design of large-scale products in different places, and relates to the collaborative data exchange application of transnational multi-party digital design of large-scale products such as helicopters. It can be widely applied to the remote collaborative research and development process of other high-end manufacturing industries (such as automobiles, ships, aircraft, etc.). Background technique [0002] The agility and personalized design requirements of the future market for product design will urge today's product development companies to adopt more remote collaborative development models to give full play to the resources and technological advantages of their respective companies, share knowledge, experience and data in product development, and accelerate product development. Deformation design, personalized design and manufacturing process. As the key technology of collaborative developme...
