用一片Ａ／Ｄ进行多通道数据采集不仅在速度上受到限制，而且难以克服通道间转换过程中引入的嗓声和道间串扰。在需要进行不同通道信号之间的相位分析时，各采样通过之间的相位误差也难以克服。介绍了多通道并行数据采集技术，给出了利用并行技术进行多通道采集以及利用并行技术进行单路信号超高速采集的软／硬件实现技术，讨论了实现并行数据采集的误差校正方法以及利用并行技术进行数据采集系统的容错设计。
Multichannel data acquisition with a single A / D is not only limited in speed, but also difficult to overcome the crosstalk and crosstalk introduced during the transition between channels. When the phase analysis between different channel signals needs to be performed, the phase error between the sampling passes can not be overcome. This paper introduces the multi-channel parallel data acquisition technology, gives the hardware / software implementation of multi-channel acquisition using parallel technology and single-channel signal acquisition using parallel technology, and discusses the error correction method to achieve parallel data acquisition and the use of parallel Technology for data acquisition system fault-tolerant design.
