本文介绍的光电跟踪系统是直接利用脉冲信号的相位信息来确定图线矢量角所属象限,用计数测时的办法检测光环对图线的偏离,经过逻辑判断驱动两个步进电机,实现跟踪头对图线的跟踪。与现有的相位信号——模拟信号——随动系统方案相比,机械结构简单、系统频带宽、维修调整方便。本文对研究图形——数据转换技术也能有些参考价值。
This article describes the optical tracking system is the direct use of pulse signal phase information to determine the quadrant of the vector line angle of the figure, with a measure of the way to detect the halo of the deviation of the line, through the logic to drive the two stepper motor to achieve tracking head Trace to the graph line. Compared with the existing phase signal-analog signal-servo system scheme, the mechanical structure is simple, the system bandwidth is wide, and the maintenance and adjustment are convenient. This article can also be of some reference value for the research of graphics-data conversion technology.
