Aiming to problem of the signal sampling software, which serves the breaking test of switching device, can＇t analyze automatically to obtain time parameters. The signal singularity detecting method based on singular value decomposition is introduced, studies are conducted with simulative breaking current signal, then automatic analyzing algorithm for time parameters is provided. The result shows that this algorithm can detect the beginning and ending position of singularing in signal properly, obtain obvious peaks which indicate the boundary and realize accurate detection of time parameters, which has great significance for improving efficiency and accuracy of the product inspection.
