当信号处理模块发现实时脉搏强度值超过强度阈值(4dB>3dB)，并且实时压力值超过压力阈值(500Pa>400Pa)时，说明拾音器已经处于肱动脉血管的上方位置，位置合适，并且贴紧皮肤。信号处理模块立即通知拾音器和控制模块。When the signal processing module finds that the real-time pulse intensity value exceeds the intensity threshold (4dB>3dB), and the real-time pressure value exceeds the pressure threshold (500Pa>400Pa), it means that the pickup is already in the upper position of the brachial artery, the position is appropriate, and it is close to the skin .
