Linux-based Platform for Open Architecture Controller and Its Modular Developing Method

Linux-based Platform for Open Architecture Controller ( POAC ), a new open architecture controller and its modular developing method are discussed. POAC divides the application software of controller into the developing system and the application system. In the developing system, PAOC abstracts a series of function modules with unified data interface and function interface. In the application system, POAC defines the model of the architecture module, realizing the interoperability and interchangeability between the architecture modules. The modular developing method entities the users to make up an application system with some architecture modules, which consist of a set of function modules. The modular developing method decreases the developing time from the standard of controller architecture to the product.     

基于Windows NT和Linux的开放式数控系统

论述了一种新的开放式数控系统——WLONCS(Windows NT and Linux based Open Numerical Contro1 System)．WLONCS把数控系统的功能实现抽象为一系列功能模块、把操作系统的任务实现表示为一组任务框架．WLONCS的任务模块是可独立运行的实现某种控制功能的程序模块，它是通过在任务框架中集成某些功能模块的功能而得到的．一组相关的任务模块组合在一起可以构成一个具体的数控系统．WLONCS可以产生基于Windows NT RTX的数控系统和基于Linux RT Linux的数控系统．
