This invention provides a method and system for monitoring and adaptively calibrating the blade condition of a hawthorn slicer based on multi-sensor fusion. It collects spindle motor current signals, blade holder vibration acceleration signals, and slice images, and extracts feature values. When the vibration feature value changes abruptly and the current feature value decreases simultaneously, blade breakage is detected, triggering an emergency stop. If breakage is not detected, the average current trend is monitored to generate a wear warning. Visual acquisition is initiated according to preset conditions to obtain the actual slice thickness. Using a pre-calibrated mapping relationship between slice thickness and current and vibration feature values, the threshold compensation amount is calculated in reverse based on the thickness deviation, adaptively correcting the detection threshold. This invention reduces the false blade breakage rate, achieves proactive wear warning, compensates for sensor drift, and ensures a high slice yield.
