摘要
伴随式心电监护能够有效地降低心脏病患者发生危险和死亡的概率。基于人体传感器网络(BSN)的无线心电监护是心功能监测的新方法和有效手段。针对伴随式心电监护中对节点小型化、低功耗以及良好的监测信号质量的要求,提出了一种50mm×50mm×10mm、30g的心电监护节点。节点包括单片心电模拟前端AD8232、超低功耗微处理器MSP430F1611及低功耗蓝牙模块HM-11;实时数字滤波保证了监测心电的信号质量;通过设计的差分阈值R波检测算法可准确地得到心律指标。节点功耗评估以及实际信号采集实验验证了节点功能。提出的节点在伴随式心电监护中具有较好的应用前景。
Ambulatory electrocardiogram（ECG）monitoring can effectively reduce the risk and death rate of patients with cardiovascular diseases（CVDs）.The Body Sensor Network（BSN）based ECG monitoring is a new and efficient method to protect the CVDs patients.To meet the challenges of miniaturization,low power and high signal quality of the node,we proposed a novel 50mm×50mm×10mm,30 g wireless ECG node,which includes the single-chip analog front-end AD8232,ultra-low power microprocessor MSP430F1611 and Bluetooth module HM-11.The ECG signal quality is guaranteed by the on-line digital filtering.The difference threshold algorithm results in accuracy of Rwave detection and heart rate.Experiments were carried out to test the node and the results showed that the proposed node reached the design target,and it has great potential in application of wireless ECG monitoring.
