摘　　要：提出在 RT- L inux上实现具有开放性、模块化、动态可重构的CNC系统的软件框架及其组成 ;介绍了 RT- Linux及其运行机制 ;给出了组成该系统基本模块 (任务模块 )的定义及任务模块之间的关系 ;任务模块间的通讯采用状态表机制实现 ;A dynamically reconfigurable and modular open architecture CNC controller based on RT-Linux is described. This system software architectural style is based on process control loops, which composed of task-modules. This CNC controller consists of the library of task modules, virtual modules system and Human-Machine interface. The task module is a basic unit of the controller. Virtual modules system is a platform for real time task-modules running and Human-Machine interface is responsible for the connection between the controller and the system. The communication between task modules is performed via state variables stored in global and local tables.
