摘　　要：为方便CCD相机采集显微镜下的图像,对显微镜的控制进行了研究;设计了一种实现显微镜自动控制的方法;利用THB6128芯片驱动步进电机实现焦距的电控调节,利用PT4115芯片控制LED灯实现照明灯光亮暗的调节,基于LabVIEW虚拟仪器平台开发主控制程序搭建外围硬件,实现显微镜的自动控制;实验证明,上位机运用程序通过串口进行数据通信向下位机发送指令,通过调节LED灯的亮暗以及步进电机转动带动载物台的上下移动,实现了在一个合适的光照和焦距下获取清晰的图像;使显微镜控制更加的简化与精确,便于图像的采集。To facilitate the CCD camera to capture images under the microscope, control of the microscope is studied. Design a method for realizing automatic control the microscope. Electrical control to adjust the focus use THB6128 chip stepper motor drive, use PT4115 chip control LED lights achieve the lights dim lighting adjustment, based on LabVIEW virtual instrument platform to develop the main control program to build the peripheral hardware, realize the automatic control of microscope. Experiments prove that the PC sends instructions to the lower computer through serial data communication, by adjusting the LED lamp light and dark as well as a stepper motor driven rotation of the stage moving up and down, achieved obtain a clear image at a suitable lighting and focus. Make microscope control more simplified and precise, easy image acquisition.
