Intelligent measuring device and method for leakage of dike building under freeze-thaw environment

Abstract

The present application belongs to the technical field of safety monitoring of hydraulic engineering, and particularly relates to a kind of intelligent measuring device and method for leakage of dike-penetrating building under freeze-thaw environment, comprising selecting a plurality of monitoring points on the dike-penetrating building, and arranging multi-dimensional sensor modules to synchronously collect multi-dimensional parameters related to freeze-thaw cycle and leakage of dike-penetrating building; constructing a hybrid wireless transmission architecture of external wireless transmission unit of data collector; preprocessing multi-dimensional parameters; calculating key characteristic parameters from preprocessed multi-dimensional parameters, and quantifying real-time risk index based on key characteristic parameters; predicting future trend according to historical data of key characteristic parameters; establishing a hierarchical early warning mechanism based on real-time risk index and trend of key characteristic parameters; and identifying and locating cracks of dike-penetrating building under freeze-thaw environment. The present application effectively improves the accuracy and intelligence of leakage measurement of dike-penetrating building under freeze-thaw environment, and saves labor cost.
