显微镜工作台定位系统的设计与实现

设计了一套基于AT89C52单片机的显微镜工作台定位系统。机械传动部分采用小模数齿轮实现机械运动和动力的传递,单片机电路控制部分实现计数脉冲的获取和电机的控制,上位机控制环节完成用户命令的发布。该系统可以按照预先设定的方式控制电机,实现显微镜工作台的二维运动,两方向重复定位精度±50μm,满足了多波长光存储实验的要求,同时为医疗检验提供了自动化手段。

Design and realization of orientation system for worktable of microscope

The orientation system for microscope worktable based on AT89C52 chip microcomputer is designed. Fine-pitch gears are used in mechanically-driven section to realize the transfer of movement and power. Circuit control section is used to gain count impulses and to control motors. Commands and data can be sent from host computer. The microscope worktable can be controlled to move according to the pre-established mode, and realize 2D movement. The re-orientation accuracy of 2 directions is ±50μm, which needs the demand of the experiments of multi-wave optical storage, and provides an automated methods for medical detection.
