摘　　要：为了在多通道数据采集中有更好的同步性,将频分复用技术引入到采集卡设计中,设计了一种新型多通道数据采集系统方案。可以很好地解决传统方法在数据采集上存在同步性不足和软硬件资源的浪费问题,验证了频分复用技术应用于采集系统的可行性。In order to accomplish synchronism for multichannel data collection, the frequency division multiplexing（FDM） was introduced into the design of data acquisition card. A new scheme for multichannel data collection was designed. This method could well solve the synchronicity shortage and software ＆ hardware resources waste problems existed in data acquisition of tradi tional method. The feasibility of FDM applied in acquisition system was verified.
