AI Technical Summary
Existing ultrasonic preservation technology is unable to adjust excitation parameters in real time according to the condition of meat and changes in the environment. It lacks the ability to fuse and perceive information from multiple sources, resulting in unstable preservation effects, insufficient adaptability to heterogeneous meat pieces, and a lack of dynamic mapping relationship and closed-loop feedback mechanism between quantitative indicators of freshness and ultrasonic excitation parameters.
A multimodal sensor is used to fuse gas composition, temperature, humidity, spectrum and ultrasonic echo information to construct an rFRI comprehensive index for freshness quantification. The PLT predictor is used to realize dynamic mapping of ultrasonic excitation levels. At the same time, a modular ultrasonic array is used to independently control sub-modules, and a closed-loop feedback mechanism is constructed in combination with echo signals. An online learning module is introduced to optimize the model.
It achieves adaptive adjustment of ultrasonic parameters, improves preservation accuracy and system response, has self-learning and self-evolution capabilities, and adapts to the stability and reliability of diverse application scenarios.
