Abstract

基于CC2530设计了低功耗、小体积的无线心电监测传感器节点。介绍了心电信号的测量原理，给出了传感器节点的硬件设计，并简要介绍了传感器节点的软件设计。基于所设计的传感器节点搭建了测试系统，测试结果表明该传感器节点能够测量心电图和心率参数，能够满足无线监测应用需求。 A low-power wireless ECG sensor node, with small physical size, is designed based on CC2530. The principle of ECG measurement is introduced. Then the hardware and software design of the sensor node is presented. Finally, a measurement system is built based on the wireless ECG sensor nodes. Test results show that the ECG sensor node can be used to measure ECG and heart rate, which can meet the application demand of wireless monitoring.
