| 摘 要： | 针对目前大多数采集系统无法实现多通道高分辨率采样及携带不方便等情况,提出了一种基于USB的多路数据采集系统的设计方法。系统利用ARM+FPGA+AD7656的系统组合实现16路通道同步信号采样,FPGA用于实现对A/D转换的逻辑控制,通过ARM7处理器对A/D转换数据进行处理,再由USB接口与计算机进行数据通信。测试结果表明,基于FPGA与ARM的多通道数据采集系统结构简单、控制方便、设计成本较低,能够准确快速地对16路信号同时进行采集。

| Abstract: | As most current acquisition systems can not implement multi-channel sampling with a high-precision and are inconvenient to carry,it has been put forward a design of multi-channel data acquisition system based on USB.The system uses the compound mode of ARM+FPGA+AD7656 to implement 16-channel synchronous sampling.The FPGA is used to complete the logic control of the A/D conversion,and use the ARM7 processor to process the data of A/D conversion.Then the system would communicate with computer through the USB ... |
