摘　　要：针对同时对多路信号进行处理的需求,借助高速模拟开关和高性能A/D转换器设计了基于FPGA的多通道、高精度数据采集存储器,实现了对32路模拟信号的采集、转换,数据经过有效的数字滤波后既可以通过LVDS总线实时上传给上位机,也可以存储到Flash存储器中。测试结果表明:采集的数据没有丢帧、跳帧的情况,能很好的还原被测信号。For processing many signals at the same time, a multi-channel, high-precision data acquisition and storage device based on FPGA was designed, where high-speed multiplexers and high-performance A/D coventer were used. The device samples and converts 32 channels analog signals,then,after passing an effective digital filter,the data can be uploaded to PC through LVDS bus and also can be stored into flash memory. Test results show that the data acquired can well rebuild the original analog signal, having no frame loss or frame skip.
