摘　　要：为满足市场对标记机系统小型化、便携化的要求,提出了一种基于ARM和MiniGUI的嵌入式数控标记机的解决方案。设计了系统的软件体系结构和矢量字库,采用实时层和非实时层的分层软件结构保障实时任务的及时处理,提供了USB和TCP/IP接口与其它系统进行数据交换,采用MiniGUI设计了系统的图形用户界面,完成了MiniGUI在ARM2410上的移植。所设计的系统有效地改善了人机接口,提高了步进电机的控制效率和质量,能够满足标记机系统的应用要求。An embedded numerical control system for marking machine tools based on ARM and MiniGUI is provided to satisfy the market need for smaller and more portable marker. The system＇s software architecture and process flow are introduced, and a kind of vector font library is designed. Hierarchical structure is adopted to guarantee the processing of real-time task in time, through dividing the software into real-time layer and non-real-time layer. Interface of USB and TCP/IP is designed to communicate with other system. MiniGUl is selected to develop the system＇s graphics user interface. MiniGUl is ported to ARM2410. The system improves the human-machine interface efficiency and the control quality of stepper motor, and satisfies the expectation of practical application.
