摘　　要：为了解决激光打标工业现场中抗干扰能力低、难以实现多机互联打标应用的困难,设计了一种新型高速数字激光扫描振镜驱动板卡。设计中以电机的物理数学模型、控制电路的数学模型、数字振镜电机伺服控制电路等方面考虑,做了详细介绍,进而设计了基于CPLD的高速高精度DA硬件伺服控制电路,并阐述了调试方法。结合打标软件数据协议设计了振镜数字多址接收软件和数据分配软件,经调试后实际打标测试,实现了高速数字扫描振镜的多机同步操作,并对单笔道、填充体小字、图形等进行了高速打标实测,达到了良好的使用效果。In order to solve the problems which low anti-interierence and can not realize the mterconnection in the industrial field. Designed a new high speed digital laser scanning mirror driving system, introduced the mathematic model of motor and control circuit, digital scanning mirror servo control system. Then designed the high speed and precision DA hardware servo control circuit based CPLD devices. Based on marking data protocols designed scanner data receiving software and data protocol allocate software, after debugged and making test, realized high speed digital multi scanning mirrors synchronous marking processing, and has tested actual marking like single line, filling type word, small circle and so on. It achieves much better results in the applications.
