多通道VXI数据采集模块关键技术的研究

Research of Key Technique of Multi-channel Data Acquisition Module Based on Vxibus

针对VXI总线C尺寸数据采集模块通道数少,通道切换不灵活的现状,对多通道数据采集模块硬件设计方法进行了研究.提出了通道自由切换,各通道自动校准以及数据存储等关键技术的解决方法,并采用DSP作为本地CPU,提高了模块测量的准确度,丰富了模块的功能.

Aiming at the less number of channels and not flexible scanning of Vxibus C-Size data acquisition module now, the paper studied the primary design method of multi - channel data acquisition module. And it presented the solution to some key problems, such as flexible scanning, automated calibration, data memory and so on. And DSP was assigned to be the local CPU, which strengthened the accuracy and function of the module greatly.
