摘　　要：主要研究了基于USB总线,以FPGA为主控单元的振镜扫描式激光标记控制系统,对其工作原理进行了阐述并对其外围硬件架构以及FPGA内部硬件架构进行了分析设计,并利用FPGA的DSP开发工具DSPBuilder对曲线插补算法进行了算法建模设计,通过仿真分析验证了在FPGA硬件实现该算法的可行性和实用性。本系统还可以通过U盘读入原始打标数据,对其进行数据处理后完成对振镜的控制,为实现脱机标刻奠定了基础。最后对激光标记控制系统进行了实际测试,结果表明,该系统可以实现实时、高速、高精度的激光标记。The galvanometer scanning laser marking system based on the USB bus is researched,which used FPGA as the main control unit. The working principle is introduced,and the system hardware architecture and hardware structure of FPGA are analyzed and designed. the curve interpolation algorithm model based on FPGA is established by using DSP Builder,and the simulation analysis result proves the feasibility and practicality of this method. The system can read the original marking data from the U disk,and complete the control of the vibration mirror after data processing,which lay a foundation for realizing the offline marking. Finally,the actual control system was tested. The results show that the system can applied for real-time,high-speed,and high-precision laser marking.
