【摘要】 为了解决钢厂带钢在切割中的跑偏问题,设计了以TMS320LF2407微处理器为控制核心及线阵CCD为边缘检测器件的自动对中系统。系统采用CPLD设计线阵CCD动态驱动电路,解决了CCD输出信号受环境影响而产生的饱和失真和背景与物体无法分开的问题,大大提高系统的抗干扰能力。系统检测精度高、运行速度快、实时性强。更多还原

【Abstract】 In order to resolve the problem of bias in cutting of steel belts in steel factories,a automatically centering system based on TMS320DLF2407 MCU and CCD linear array was presented.CPLD was used in the CCD dynamic driving circuit so as to resolve the problem of saturation distortion and mixture of background and detecting object,which was caused by the affection of environment to the CCD output signal.As a result,the system has very good anti-interference ability,high measurement precision,short running time and can work in real-time situation.更多还原
