摘要
针对无损检测技术中激振检振技术对相位信息应用的工程需求,基于MAX1308设计了一种8通道并行数据获取系统,数据完整地保持了各通道间的相位信息。并根据工程需求设计了调理电路,系统可以完成电压±5V之间的信号采样,每通道的采样速率达到456ks/s。
To meet the technique requirements of vibration absorber acquisition system based on MAX1308 was designed in this paper, in nondestructive testing technology, an 8-channel parallel data in which the data could keep the phase information integrality between each channel. According to the requirements of engineering, the conditioning circuit was designed, the system could completely get the signal samples between plus and minus 5 V voltage, the sampling rate can be up to 456 ksps per channel.
