摘　　要：为了提高数字信号处理的快速稳定性,介绍了一种在轴承故障诊断系统中作为核心的数据采集卡的设计方法。该采集卡采用高速浮点TMS320C6701DSP,外接AD9042和工业标准集成电路,实现了信号的采集与处理,及主机与DSP间的数据传输。实验结果表明,这种设计方法应用于轴承的故障诊断中,完全可以满足数据采集及处理的需要。In order to advance the speed and stability of digital signal processing, a design of data acquisition card was introduced, which was used as core in bearing fault diagnosis. Data acquisition card adopted float and high-speed TMS320C6701DSP, external connected with AD9042 and industrial standard integrated circuit. Signal collection and processing, and transmission between host and DSP were realized. Experimental results indicate that the design applies to the bearing fault diagnosis, can satisfy demand of data collection and signal process completely.
