High-precision fuel oil liquid level detection method and system and storage medium

Abstract

The invention discloses a high-precision fuel oil liquid level detection method and system and a storage medium, and the method comprises the steps: training a neural network model based on a tested spectrogram and a calibrated liquid level height to obtain a liquid level height compensation model; and training based on empirical data to obtain an actor-commentator network. Inputting a spectrogram, measured in real time, of an output signal of the signal processor at the current temperature into the liquid level height compensation model to obtain a predicted liquid level compensation height; inputting the current real-time state into an actor-commentator network to obtain an optimal liquid level compensation weight; the liquid level compensation height after temperature compensation is obtained in real time on the basis of spectrogram detection, and the optimal liquid level compensation weight strategy is obtained on the basis of state detection, so that the liquid level compensation height is corrected, and a high-precision liquid level detection result is obtained. According to the invention, environmental factors and experience factors are measured as a whole, the precision of fuel oil height detection is effectively improved, and the method has good practicability.
