摘要
设计了一种高速数据采集系统,采用TMS320F2812型号的DSP和MAX1308型号的AD转换器完成对8路同步信号的采集,通过USB接口芯片CH372将采集到的数据实时传输给计算机,计算机对整个数据采集过程进行控制并显示。该系统对单路的数据采集,可以实现800kSPS的实时数据传输,8路同步采集可以实现400kSPS的实时数据传输。
The high-speed data collection system is introduced.The high-speed DSP TMS320F2812 of TI and MAX1308 of MAXIM is used to collect eight channels simultaneous signal,the USB chip CH372 is used to send the data to computer real-time,the computer is used to control the progress of data collection and display.When collect the signal channel data,the max collection rate is 800kSPS,when collect the eight channels data and real-time transmission,the max collection rate is 800kSPS.
