数据采集系统在测量、控制、信息处理等多学科领域有着广泛的应用,传统的以单片机为核心的多路散据采集系统原理简单、技术成熟、选型方便,但也存在的外围芯片多、电路复杂、不易升级与改进等缺点;鉴于此,提出了一种以FPGA为逻辑控制核心的多路数据采集系统设计方案,重点介绍了关键器件的选择、FPGA功能模块设计、FPGA外围电路设计；并结合部队实际需求,成功地将这一方案应用到武器装备测试系统的研制过程中,体现了较高的军事及经济价值.%Data acquisition systems have extensive use in the field of science. The general data acquisition system based on MCU have many advantages such as simple principle, mature technology, convenient selection, but also have many shortcomings such as too many chips, sophisticated circuit and difficult upgrade. So the design plan of data acquisition system based on FPGA is given in this paper. Selection of important electronic device, design of FPGA and outside circuits are introduced especially. According to the army demand* the design plan is successfully applied to weapon testing system. High military and economic value is shown.
