摘　　要：在自动引导车(AGV—auto-guided vehicle)沿着引导线移动过程中,当光电传感器距离引导线的高度、外界光照的亮度等变化时,反射光的检测电压也随之变化,利用PIC16F819内置的ADC模块,对检测的电压进行模数转换,由输入的数字电压得到的动态阈值能够正确识别引导线和地面。该方法具有较强的抗干扰性,满足实际现场引导线识别的要求。During the AGV（auto-guided vehicle） was moved along guide line,when ambient environment was changed,such as the high from photoelectric detector to guide line and the brightness of ambient light,the detection voltage of the reflected light also was changed,by ADC modules in PIC16F819 device,the analog detection voltage was converted to the digital voltage,the guide line and the ground can was identified by the dynamic threshold calculated from input digital voltages.This method has strong anti-interference,and meets the requirement of actual field guide line identification.
