Latest Patents

One of Lei Wang's latest patents is an "Intelligent inversion method for pipeline defects based on heterogeneous field signals." This method involves acquiring heterogeneous field signals, performing abnormality judgments, correcting base values, and applying denoising treatments. The process includes padding the denoised signals, unifying them into consistent sizes, and conducting nonlinear transformations. Additionally, a sparse autoencoder is designed to extract primary characteristics, followed by a classification of pipeline defects based on their dimensions. A multi-classification neural network is then utilized to classify the signals and extract deep characteristics, ultimately constructing a random forest regression model for intelligent inversion of defect sizes.

Another significant patent is the "Method and system for blast-induced vibration monitoring of tunnels in high asymmetric in-situ stresses." This invention provides a method for monitoring blast-induced vibrations using triaxial vibration sensors fixed at various radial depths within surrounding rocks. The system enhances safety and efficiency during tunnel excavation by accurately monitoring blast vibration velocity and acceleration.
