A basic prototype of soft CNC system is built based on Windows. NET development platform and real-time extension kernel RTX, and system functions are devided by modules based on non-real-time and realtime component technologies. Also, the multitask scheduling model is analyzed and designed in depth, and realtime and multithready execute techniques are introduced to accomplish communication task.%基于Windows.NET开发平台及实时扩展内核RTX构建了全软件数控系统基本原型,结合非实时任务组件和实时任务组件技术对系统功能进行了模块划分,深入讨论了多任务调度策略,并引入多线程技术和实时技术完成系统的通信任务.
