摘要
设计了一种其于PCI高分辨率线阵CCD图像采集系统,它由光学镜头、硬件电路与机械传送装置3部分组成,其中CPLD是硬件电路中的核心,主要实现CCD驱动、专用A/D转换时序、FIFO读写控制、以及步进机驱动控制信号,采用PCI接口实现与上位机通信。实验结果表明,系统设计符合设计要求,并且可广泛用于相关检测领域。
A linear CCD image acquisition system with high resolution is designed based on PCI, which contains three parts-optical lens, hardware and mechanical transmission device. CPLD is the brain of this hardware, and mainly realize that drive linear CCD, generate analogy-to-digital converters＇timing, control FIFO＇read and write and provide stepping motor with driving signal,and this system uses PCI interface to communicate with PC. The result indicates,it accords with the designing requirement that the system is designed. It can be used in inspection system widely.
