This paper designed a multi-channel data acquisition method based on anti-fuse FPGA aimed at the hardware part of the multi-channel data acquisition ceU. The paper analyzed the hazards of the inrush current and how to restrain it and elaborate the superiority of the anti-fuse FPGA re to other types of FPGA and the componerUs of the module. The anti-fuse FPCA device A32100DX was used to be the master controller of the system to control the A/D conversion, the selection of the analog switches'channels and implement the function that converts the serial digital signals to parajlel.%针对多路高速数据采集单元硬件部分,设计了基于反熔丝FPGA的多路数据采集方案.分析了浪涌电流的危害以及抑制浪涌电流的方法,阐述了反熔丝FPGA的优越特点,并对系统的各组成模块进行了详细的说明.设计采用反熔丝FPGA器件A32100DX作为系统的主控器件,实现了A/D转换、模拟开关选通控制以及数字信号的并串转换等功能.
