This application discloses an intelligent monitoring method and system for the status of medical devices based on the Internet of Things (IoT), relating to the field of medical device monitoring. First, it utilizes information such as the device's service life and operating conditions to train a unique aging model for each device, predicting its normal performance parameters at the current stage of its life cycle. Then, by subtracting this predicted normal aging value from the real-time monitoring data, a clean residual signal is obtained. Subsequent anomaly detection will only target this residual signal; any significant fluctuations will likely point to an impending abnormal failure. This prediction-subtraction-detection model fundamentally solves the problem of aliasing between normal aging and abnormal deviations in data characteristics and adapts to the individual differences of devices, thereby accurately identifying true impending failures and significantly reducing the false alarm rate.
