This invention provides a bed-mounted sleep breathing state monitoring system and method. It collects bed-mounted pressure signals generated during the user's sleep process using an under-bed pressure sensor module. Based on these signals, it determines the start and end times of candidate sleep breathing abnormalities. The bed-mounted pressure signals from the start to the end time are then input into a pre-set deep neural network for feature extraction and classification, ultimately determining whether a sleep breathing abnormality event exists. This method accurately captures the complete temporal features of sleep breathing abnormalities without relying on fixed time window segmentation, effectively avoiding issues such as event truncation and feature aliasing. It achieves adaptive localization and automated detection of sleep breathing abnormalities, significantly improving the accuracy and completeness of sleep breathing abnormality event identification and reducing the risk of missed or false detections.
