摘要
为了使纠偏控制器能对卷材按颜色的方式进行纠偏,提出了使用颜色传感器TCS230代替目前纠偏控制器上广泛使用的光电传感器,采用两传感器互补交错布置的结构,构建采集系统硬件平台。基于脉宽测量法,对TCS230RGB 3种滤波片的输出值进行了采集、分析和相对比值处理,并对颜色进行了模糊识别,实现了采集系统滤波片的自动选择。实验结果表明,在卷材色彩不同的情况下,系统能够自动对滤波片进行最优选择,达到了纠偏控制器的高精度控制要求。
The method of replacing traditional photoelectric sensor with TCS230 color sensor was put forward to realize coil correction in color mode.The hardware of collection system was built based on structure of complementary staggered layout between the two sensors.In the case of RGB three filters of TCS230,the output values were collected according to the measuring method of pulse width and these data were analyzed and relative ratio processed;the colors were fuzzy identified;and automatic selection of acquisition system filter was implemented.The experimental results showed that the optimal filter can be automatically selected when the coil materials are of different colors,and the requirement of correction controller with high accuracy is achieved.
