摘　　要：DSP系统具有高速、小型化、稳定性好、精度高和集成度高等特点。本文设计了一种基于DSP技术的线阵CCD数据采集系统,以TMS320VC5502型DSP和TLV1572型A/D转换器为例,分析了CCD输出数据和A/D转换数据的工作时序,详细介绍对线阵CCD输出视频信号的数据采集过程,并通过MAX232器件把采集结果传给PC机。该系统设计方案电路简单,可靠性好,易于实现,具有一定的通用性。A DSP system is a minitype integrative system with high speed, high precision and stabilization. A data acquisition system with linear CCD is designed. Using TMS320VC5502 and TLV1572 A/D converter, the time sequence of data outputted by CCD and data converted by A/D converter are analvzed. The procedure of how to acquire the video signal from the linear CCD and how to transmit these signals from MAX232 to a PC is also introduced. The system with general purpose is designed with high reliability and can be implemented easily.
