摘要
介绍一种基于650 nm波长激光的三维坐标测试仪电子控制系统设计。该电子控制系统采用ATMEL89C2051单片机作为主控器件,采用S9013三极管作为激光射头的电源驱动器件。通过改变单片机输出的频率控制三极管的导通周期产生可变电压作为激光射头的工作电源,从而控制激光射头产生明暗的光线。
In the paper, the design of 3 -D laser measure electronic- control system is given and the laser＇s wave is 650 nm in the system. ATMEL 89C2051 is used for centre controller. Transistor S9013 is used for driving the laser diode. The output voltage of S9013 can be changed with the changing frequency of high and low voltage, thus the power can control laser diode converting between dark and light.
