AI Technical Summary

Technical Problem

Traditional single-loop water filling methods rely on fixed parameters and static thresholds, which fail to respond to changes in temperature and pressure in real time. This results in inaccurate water filling control, which can easily lead to insufficient water filling, overfilling, or liquid level fluctuations, posing safety risks.

Method used

By adopting a real-time temperature-pressure compensation mechanism and adaptive control strategy, the water filling rate and liquid level threshold are adjusted in real time through a neural network model to achieve dynamic water filling mode switching, thereby improving the accuracy of volume measurement and the safety and efficiency of the water filling process.

Benefits of technology

It significantly improves the accuracy and adaptability of water filling control, reduces manual intervention, enhances the reliability and stability of system operation, and avoids problems of insufficient or excessive water filling caused by changes in operating conditions.
