摘要
常规的电容层析成像系统只能提供典型层面的二维断层图,但多数过程发生在三维空间。基于虚拟仪器技术,设计开发了一种不经过二维断层成像的直接三维电容层析成像系统。该系统可分为传感器系统、数据采集系统和成像计算机3部分。数据采集系统以内置电容传感模块的C8051F700单片机为核心构成,采集各极板间的电容数据。计算机完成图像重建,图像显示以及ECT系统控制等功能。由于采用高集成度的C8051F700和LabVIEW软件开发平台,所开发的系统结构简单成本低,易实现远程监测。
A conventional electrical capacitance tomography （ECT） system can only generate 2D tomograms of a typical sec- tion. However, most processes take place in 3D space. A direct 3D ECT system without using 2D tomoga＇ams was developed based on virtual instrument technology. The system can be divided into three parts ： sensor system, data acquisition system and imaging computer. The data acquisition system took C8051F700 ,a capacitive sensing mixed-signal MCU, as the core to acquire the capaci- tance data of all electrode pairs. The computer implements image reconstruction, image display and ECT system control. Since C8051F-/00 is a highly integrated chip and LabVIEW is used as software environment, this system is simple in structure, low in cost and easy in remote monitoring.
