一种新型的局域网嵌入式数控系统

With the development of computer and network technology and the application of machine tool, in order to resolve the traditional stand-alone mode, enhancing the efficiency of NC system. Through introduce CAN(Controller Area Network) bus , a new type of LAN(Local Area Network) was designed. The network system structure and the embedded NC system based on ARM9 and motor control chip MCX314As was given. This LAN embedded NC system can realize one computer control more NC tool and resolve the problem of low real-time which result from network transmission. The realization of whole system can improve efficiency of NC process and enhance real-time ability.
