摘要
介绍了数据采集系统的发展状况,分析了高速数据采集系统应满足的性能要求,给出了系统硬件结构图及主要模块电路,说明了系统软件的结构与主要程序流程。使用AD976A为A/D转换芯片,DSP(TMS320C5402)为中央控制芯片,FT245BM为USB2.0通信接口芯片,FLASH为数据存储芯片,最终完成了高速数据采集系统的设计方案。
It introduces the status of the data acquisition system, analyzes the function demands of the high speed data acquisition system, gives in detail about the system frame and the circuits of the main module. In this system, it uses AD976A as the analog to digital converter, DSP（TMS320C5402）as the CPU, and takes FT245BM to realize the USB2.0 communication interface function, FLASH memory is used to backup the sampling data, It shows the design scheme for high speed data acquisition system.
