摘要

弹道靶道空间基准标定装置由多台步进电机驱动

在控制软件的管理下将标定装置的中心轴调节到光轴中心位置。在虚拟仪器软件Lab VIEW环境下

用图形化编程语言实现采集位置敏感探测器（PSD）反馈的模拟信号并通过A/D采集卡进行A/D转换。根据以数组形式得到的信号通过串口通信

使上位机软件对PSD反馈的光斑位置信号进行实时监控并控制步进电机的旋转

实现光斑逼近到标定装置的中心轴。基于PSD的步进电机控制系统具有良好的稳定性和准确性

已应用在弹道靶道空间基准标定装置中。标定结果表明:在该控制系统下的坐标标定误差小于1 mm。

Abstract

The ballistic range spatial benchmark device is driven by multiple stepper motor

and under management of control software

center axis of calibration device is adjusted to center position of optical axis. In the Lab VIEW environment

graphical programming language is used to collect analog signal feedbacked by position sensitive detector（ PSD） and transform analog to digital signal by A / D acquisition card. According to signal obtained by serial communication

the upper PC software monitor the spot position signal on the PSD in real-time and control rotation of stepper motor

and realize light spot close to the central axis of calibration device. Stepper motor control system based on PSD has good stability and accuracy

and has been used in ballistic range spatial benchmark device. Calibration results show that calibration error of coordinates is less than 1mm under the control system.
