Abstract

Abstract

In this paper, a set of a fast test system for electromechanical response time, using PXI data acquisition platform and MATLAB for data analysis, is built to measure the fast response time of the control rod drive mechanism (CRDM) and filter out the noise interference in the test environment. This test system can collect the real-time and high-frequency position signals of the control rod quickly and uses the moving average filtering and segmental curve fitting to filter and fit the position data of the control rod. Besides, the test system uses the FFT spectrum analysis to verify the effect of signal denoising. This test system is used in the electromechanical response time test of the CRDM in the first scram system of the thorium molten salt reactor-liquid fuel 1 (TMSR-LF1), demonstrating the test system in this study is consistent to the requirement of the CRDM electromechanical response time test on feasibility, reliability and applicability.
