摘　　要：为使数控系统软件可重构,提出一种面向活动对象的软件设计方法,给出设计原理、实现方法;以实际应用为例,阐明设计方法、重构流程及重构结果。该方法基于面向对象设计,并给每个对象赋予一个独立执行线程、事件队列和状态机。活动对象相互独立、不共用资源、能够独立执行,通过事件队列与其他对象通信,以"出版-订阅"的方式投递和接收事件。在该方式下,数控系统的重构复杂程度低、修改便捷、重构效率高。To let CNC system software reconfigurable, an active object oriented software design method was proposed, and its design principles were given. Based on the actual application as an exam- ple, this paper expounded the design method, reconstruction process and reconstruction results. The method based on object--oriented design endued each object with its own thread of execution,event queue and state machine. The active objects,which were independent and did not share resources,com- municated with other objects through the event queue, deliver and receipt events in publish--subscribe way. In this way,a new reeonfigurable CNC system was constructed,with low degree of complexity, convenient modification and high reconstruction efficiency.
