干涉式非接触眼压计中AT89c51控制系统
AT89c51 Micro Control System of the Non-Contact lntraocular Pressure Measurement Based on Laser Interference
【摘要】 文中详细介绍干涉式非接触眼压计中的AT89c51单片机控制系统。AT89c51单片机以串行控制方式驱动步进电机。由定时器中断控制电机运行速度,同时对弱光检测单元获得的脉冲信号进行计数并显示。
【Abstract】 In this paper,the AT89c51 micro control system of the non-contact intraocular pressure measurement based on laser interference is introduced in detail.The AT89c51 microcontroller is used to drive the stepping motor in serial control mode,control the velocity of the motor through interrupt of Timer,count and display pulses from the faint-optical signal detection system.
