To ensure that the electrical capacitance tomography (ECT) system meets the requirements of multiphase flow parameter measurement in aerospace field, an ECT system based on the CPCI industrial bus standard is designed. A high-performance field-programmable gate array (FPGA) chip is used as the main control chip to realize the integrated design of signal excitation module, multiplex switch module, data processing module, data demodulation and transmission module. The signal is preprocessed with signal filtering, amplification and phase-sensitive demodulation, and then the demodulated capacitance data is transferred to the host computer through the CPCI industrial bus interface. Finally, the image is reconstructed in the host computer. The experimental results of ECT system show that the image acquisition speed can reach 1 785 frames per second at 1 MHz excitation signal with 8 electrode sensor and 10-cycle test signal for demodulation. The system can operate under a SNR of above 60 dB, while the imaging results have good spatial resolution.
