激光精密去重机微机自动控制系统研究

Research on Automatic Control System of Laser Fine Weight Adjusting Machine

解决了利用普通型微机对激光精密去重机进行自动控制的难题。用微型计算机、D/A转换接口卡、步进电机控制器、混合式步进电机和一些必要的辅助单元,完成对激光精密去重机工作电压、重复频率、激光器头部定位的精确控制,克服了激光器中高频、高压等强电对微机的干扰和冲击。经过长时间的现场运行,没有发生误动作和安全问题。

The automatic control system for laser fine weight-adjusting machine is introduced in this article. The system is composed of PC, D/A card, step-motor, step-motor controller and other supplementary components. By using the system, it can control the laser trigger frequency and output energy and to locate the laser beam precisely.
