摘　　要：目前数据采集记录仪体积较大,采样频率低,记录通道少,记忆空间易受干扰而多变。本系统以Xilinx的Virtex-5系列现场可编程门阵列(FPGA)芯片XC5VLX30作为核心控制单元;采用ADI公司的高速AD进行模数转换;外围采用多片并口存储器作为存储单元,延长记录时间。本系统能够采样16通道以上、精确度8位模拟信号,采样速率能达500 Mbps以上,并把采样数据无线传输给上位机进行处理。Nowadays,-the-data-acquisition-recorder-is-featured-with-large-volume,-low-sampling-frequency,-and-less-recording-channels.-Its-memory-space-is-changeable-and-susceptible-to-interference.-The-core-control-of-this-system-is-Xilinx-Virtex-5-XC5VLX30-series-Field-Programmable-Gate-Array(FPGA)-chip.-It-adopts-the-high-speed-AD-of-ADI-Company-to-accomplish-analog-to-digital-conversion.-Peripheral-unit-employs-multiple-parallel-memories-as-storage,-which-can-extend-the-recording-time.-The-proposed-system-is-able-to-sample-more-than-16-channels-of-analog-signals-with-8-bit-precision.-The-sampling-rate-can-reach-above-500-Mbps.-And-the-sampled-data-can-be-transferred-wirelessly-to-the-PC-for-processing.
