The results show: the principle of the heart sound sensor is practicable; the CS theory can acquire the applications expected in compression and recovery of the heart sound; the convergence node of WSN can work normally and staidly. 通过实验证明:心音传感器的原理切实可行;压缩感知理论能够在心音采集、压缩和恢复的应用中达到预期的要求;无线传感器网络的汇聚节点能够正常稳定的工作。
