摘要
详细叙述了用USB控制器CY7C68013与A/D转换器ADS8364,构成高精度多路同步数据采集卡的过程,并给出了相应的前端电路和FPGA的控制流程。数据采集卡通过USB协议进行数据传输,增加了数据传输的有效性和采集卡的通用性。ADS8364可以进行6通道高精度的数据采集,符合大部分的数据采集要求。通过运用FPGA对数据采样,传输等进行控制,并在传输过程中进行一些基本的数据处理。
The paper describes a multi-way synchronization data acquisition card made up of USB controller CY7C68013 and AD converter ADS8364. Its front-end circuit and the FPGA control process are given. The data acquisition card uses the USB agreement to transfer data, guaranteeing the effectiveness of data transmission and the universality of the card. ADS8364 can process 6-channel high-precision data acquisition, meeting most of the data collection requirements. FPGA is used to sample the data, control the transmission, etc. , and make some basic data processing in the process of transfer.
