Research on concurrency control mechanism for collaborative of virtual prototype
虚拟样机协同设计并发控制策略研究 *

To contrapose such problems as large volume of data, long-term transaction process and nested layer in collabora-tive of virtual prototype, this paper established a new strategy of collaborative design. Then discussed the relationships among structure, transaction submission, the inter-lock mechanism and conflict harmonization. According data requirements to repli-cate contents, other stations can read data and show the graph when data are changed. It is verified that the concurrency con-trol strategy not only enabled the collaborative users handle shared resources freely, but also ensured the agility concurrency control and the consistency of real-time data by an application example.
