摘　　要：目前诸多心电传送系统的发射电路都较为复杂.本系统以ARM为控制中心的设计,采用先调频(V/f)后解调(f/V)的工作方式,其心电发射机具有电路简单、功耗低、发射频率稳定的优势.采用软解调方案,即通过FM接收机接收心电双调频信号,然后经放大整形,再经软件解调,经积分电路还原为心电图信号,显示在TFT显示屏上.通过串口在PC上显示心电波形,实现对患者实时心电监护,达到心电监护便携式设计的目标.它不仅可在家庭、运动场等小范围内对老年人、运动员、患者进行心电监测,还可以经心电远程传送进一步实现基层及中心医院的心电监护与诊断.At present more ECG transmission system transmission circuit is many complexes. This system in the ARM for the design of the control center, the first frequency modulation （V/0 after demodulation （f/V） way of working, the ECG transmitter has some advantages such as simple circuit, low power consumption, the advantages of stable transmission frequency. The scheme of soft of demodulation by FM receiver receive ECG double frequency modulation signal, and then plastic enlargement, then through software demodulation, the integral circuit reduction for ECG signal, show on the TFT screen. Via a serial port on the PC display of ECG waveform, To realize real-time ECG monitoring for patients to achieve the goal of the portable ECG monitoring design.It not only can be in the family and playground and other small scale for the elderly and athletes and patients with ECG monitoring, also can send further implement individuation to electric remote ECG monitorin and diagnosis of the basic and central hospital.
