摘　　要：为确保生理参数监护仪健康异常自动报警的准确性,采用小波变换模极大值方法消除生理信号的噪声污染;分析了医学传感器信号和人体生理信号的特征,基于小波能量理论建立了典型故障引起信号异常的能量特征关系;通过信号能量特征模式匹配,辨别信号异常是否由生理病变引起。最后通过实验证明了报警模型的有效性。It proposes the models of intelligent health alarm for the remote monitoring services in the communities or hospitals. To ensure the alarm accuracy, it uses the wavelet transform modulus maximum to remove the signal de-noising. It analyzes the different characteristics among the abnormal signals, and establishes the relationships between the abnormal signals and their wavelet energy. The reason can be recognized that lead to the abnormal signals by the pattern matching of the energy characteristics. The experiments demonstrate the effectiveness of the models.
