A water level precision optimization method and system based on a high-precision constant-current bubble water level gauge

Abstract

The application provides a water level precision optimization method and system based on a high-precision constant-current bubble water level gauge, and belongs to the technical field of hydrological monitoring. The method comprises the following steps: constructing a working condition characteristic vector at the current time based on multi-source data; compensating the reading of a back pressure sensor to obtain a first water level value; matching the working condition characteristic vector at the current time with a pre-stored optimal compensation parameter solution set; in response to the matching degree being greater than or equal to a preset matching threshold, using the matching compensation parameter in the optimal compensation parameter solution set to correct the first water level value to obtain a final optimized water level value; in response to the matching degree being less than the preset matching threshold, generating an optimization parameter based on a preset correlation matrix; inputting the first water level value, the optimization parameter and the working condition characteristic vector into a residual correction model to obtain a water level residual correction value; and adding the first water level value and the water level residual correction value to obtain a final water level value. The application improves the measurement stability and accuracy of the bubble water level gauge.
