摘　　要：介绍了一种新的基于多进程共享环形缓冲区的虚拟仪器结构 ,并将Petri网理论引入到虚拟仪器领域 ,用Petri网对多进程虚拟仪器进行建模 ,然后分析了它的并发与冲突、活性、安全性等结构特性。The design of virtual instrument structure based on multi-process sharing round buffer area is put forward in this paper, and the Petri net theory is introduced into the domain of virtual instrument. Petri net model of the virtual instrument structure is built, and its characters such as concurrence、conflict、activity、security etc are discussed. Finally, its application in virtual instrument platform is expounded briefly.
