This invention discloses a multi-channel PPG wide-range blood oxygen saturation estimation method for high-altitude environments, belonging to the technical field of physiological signal processing and dynamic blood oxygen monitoring. The method first acquires multi-channel PPG signals and reference measurements, and obtains standardized data through preprocessing such as time alignment, invalid data removal, and noise suppression. Then, it constructs an estimation model containing a quality-aware feature extraction module, an attention-based cross-site fusion module, and a regression head. Reliability masks are generated through multi-scale convolution to optimize feature quality, and multi-head self-attention is used to fuse features from multiple sites. Training employs a composite loss function combining MSE and PCC to iteratively optimize parameters. This invention can accurately handle PPG signal noise interference in high-altitude environments, achieving accurate and continuous estimation of blood oxygen saturation over a wide range of 70%-100%, making it suitable for high-altitude hypoxia monitoring scenarios and highly practical.
