摘　　要：设计了基于STM32微控制器的激光打标控制系统,对激光打标系统的几何畸变进行了分析,并提出了简化的矫正方法。使用微控制器模拟振镜控制传输协议(XY2-100)控制振镜扫描,同时控制激光器的开关,完成对打标过程的控制。使用SDRAM和NAND Flash增强微控制器的数据处理能力,并实现离线打标功能。采用多项式拟合的方法,拟合出简单有效的桶枕形复合畸变误差计算公式,并对其加以实际应用,使激光打标系统可以满足实际打标要求。Laser marking control system based on STM32 microcontroller was designed. Through analyzing the geometric distortion of laser marking system,a simplified correction method was presented. To control the laser marking process,the microcontroller was used to simulate the XY2-100 transmission and control protocol,which can control galvanometer scan and laser switch. A SDRAM and a NAND Flash are used to enhance the data processing capability of the microcontroller,and offline marking function is achieved. Based on polynomial fitting,a simple and effective formula to correct barrel distortion and pincushion distortion is proposed. Using this method,this laser marking system can meet the actual marking requirements.
