摘要： The present invention provides a method and a system for quickly eliminating signal spikes of structural health monitoring in civil engineering, including the following steps: (1) quickly identifying, by using a threshold method, a spike position in a time domain; (2) extracting spike features in a time-frequency domain through wavelet transform for a signal within a set range near the spike position; and (3) eliminating spike feature components in wavelet coefficients, and effectively eliminating a spike through inverse wavelet transform. The method and system combine the advantages of a high calculation speed of a time domain method and high resolution of a time-frequency domain method, which can make an algorithm fast and accurate. In addition to eliminating a spike, the method and system also retain wanted signal components, and have good applicability to structural health monitoring signals in civil engineering with complex time-frequency characteristics and a large amount of data.
