A Distributed Online Valve Monitoring Method Based on NB-IoT

Abstract

This invention discloses a distributed valve online monitoring method based on NB-IoT, belonging to the field of valve monitoring technology, including the following steps: S1, obtaining low-dimensional observation vectors; S2, by improving the WDCNN model, extracting deep features through complex domain convolution, correcting the probability distribution boundary using manifold curvature, superimposing auxiliary noise to calculate the sensitivity index, and weighting the peak value of the output signal-to-noise ratio to obtain robustness confidence; when the confidence exceeds a critical value, generating an interruption signal; S3, outputting a nonlinear state dataset; S4, outputting the topological fingerprint of the current waveform; S5, generating matching determination results; S6, performing split processing based on the matching determination results; S7, optimizing the transmission signal based on NB-IoT technology using high-dimensional lattice theory encoding and lattice basis reduction. This invention overcomes the limitations of traditional methods such as high power consumption, single feature extraction, and low transmission efficiency, providing an intelligent solution for valve online monitoring.
