摘　　要：以ARM9和FPGA作为核心处理器,并以Windows CE.NET 5.0作为开发平台,采用了多线程技术实现各功能模块的并发处理,研制了一种基于嵌入式平台的高速激光雕刻控制系统。为实现能量补偿,设计了调节电路来调节激光器输出功率的大小。针对高速激光雕刻的特点,着重分析了一种改进型S曲线加减速控制方法,并将其应用于系统设计中。系统已经用于某类激光雕刻机,实现了高速高精度雕刻。A design of high-speed laser carving control system based on embedded system was presented.ARM and FPGA are the kernel processors of the control system,which takes Windows CE.NET 5.0 as the software development platform and implements concurrent processing of the functional modules by the multithread technique.A regulating circuit by which the laser output power can be adjusted was designed to engrave multi-grey image.The paper emphatically analyzed an improved S-curve acceleration and deceleration control method for high speed laser sculpture.It was proved that the control system can effectively improve the efficiency and the processing quality of high-speed laser engraving machine.
