AI Technical Summary

Technical Problem

Existing methods for detecting penicillin fermentation liquid levels suffer from problems such as inaccurate measurement, susceptibility to interference, delayed control, reliance on manual intervention, and inability to make real-time dynamic adjustments. These issues make it difficult to meet the demands of modern fermentation industries for high-precision and high-stability automatic control.

Method used

A machine vision-based intelligent liquid level recognition and dynamic control method is adopted. Through video acquisition, image preprocessing, image segmentation, gradient-liquid level mapping database and time series analysis, combined with multi-dimensional indicators (liquid level value, rate value, fuzzy value), automatic control is achieved, and a complete reference standard selection scheme is constructed.

Benefits of technology

It achieves non-contact precision measurement, intelligent multi-parameter decision-making, and fully automatic closed-loop control, which improves the stability and yield of the fermentation process, reduces manual intervention, and improves response speed and control stability.
