摘要
为了方便用CCD相机采集显微镜下的图像,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。上位机通过控制GPRS给单片机发送指令,然后单片机再控制步进电机运动和调节灯光的亮暗,实现显微镜的自动控制;实验证明,上位机通过GPRS,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。
In order to use the CCD camera image acquisition under the microscope is convenient,design a method to realize the automatic control of the microscope,drive the stepper motor to achieve the focal length controlled by THB6128 chip control, LED lamp and the lamp can light the dark regulation by the use of PT4115 chip.The host computer through the GPRS control to give instruction to the MCU,then MCU to control stepping motor and adjust the lighting brightness,to achieve automatic control of microscope;experiments show that the host computer through the GPRS command,the crew sent LED,by adjusting the brightness of a lamp and a stepper motor rotates to drive the next stage mobile,can obtain the clear image in a proper light under the micro- scope and the focal length;more simplified and accurate control,easy image acquisition.
