摘要
在介绍电容层析成像系统组成原理的基础上,重新构建了一套数字化的数据采集系统,具有较高的采集速度和分辨率,着重分析了FPGA控制A/D采集,DSP响应中断进行DMA传输的有关问题。
On the basis of introducing the principal of Electrical Capacitance Tomography system, a digitalized data acquisition system is reconstructed, which has high acquisition rate and resolution. In this paper, some problems about the A./D acquisition controlled by FPGA and DMA transmission after responding the interrupt of DS Pare analyzed particularly.
