摘　　要：详细描述了μcos-Ⅲ在数控系统中的应用。根据数控系统的实时多任务的特性,提出了数控系统的运行结构和模块结构,在此基础上给出了数控系统任务的划分,以及任务间同步的实现,采用优先级天花板协议避免任务间优先级逆转。最后给出了基于数控系统的实现。In this paper, the μcos-III real time system is used to construct numerical control system. The modeling and running architecture of the numerical control system is briefly introduced. The data operation is executed in a critical section （by disabling interrupts and semphore）, so that the data always maintain consistency. A method is proposed forμcos-III to implement a periodic task.μcos-III is successfully applied to build a embedded CNC controller, and it has been widely used in industry.
