Research On Open Controller Software Based On Component Technology

In this paper, it researches the open numerical control system based component technology. We quest for the specialty and technique of the open numerical control. The controller is based the idea of the open system and take the operating system as the plat of the real-time controller. It analysis the methods to accomplish the real-time tasks.It's important to note that there are three levels of openness that one can achieve in implementing a control system. The first level is "Open Environment Controller". The second level is "Open Environment with Common interface Controller". The third level is "Open, Modular Architecture Controller". These levels are realized by vary technology. In the paper, it mainly reach the "Open, Modular Architecture Controller". In this level, we take the operating system as the application plat, and think the component technology as the implement technology.COM is a platform-independent, object-oriented system for creating binary software components that can interact. COM not only enhance the interoperability of the open system, but also redound to implement the interface of the open system. The EzCOM technology is expand from the COM technology. The application of the EzCOM help to realize Chinese open system.Zyco operating system provide the support for the component technology. In this paper, it researches the specialty, the problem faced and the implementing methods of the real-time task based the Zyco operating system. It put forward the basic method of the real-time system using the general operating system.In this papers, it researches the implementing method of real-time system. It is important to discuss five problems: the transform from the control module to compute module, the classification of the real-time tasks, the management of the tasks, software architecture and the speed problem of the high-speed cutting.Based the methods, the controller may implement high speed cutting.
