基于无线网络的心电信号系统采集电路的设计

摘要

A kind of low power consumption and low cost equipment to detect ECG signal according to the sub-health people is designed.Finally,it will be used widely.In view of the human body＇s physiological characteristics considering the external conditions and the characteristics of each CC2431 chip,we put forward the new collection structure,established circuit modules,use multisim related simulation software test it to improve the reliability of the circuit as far as possible.%针对亚健康人群及康复阶段心疾患者设计了一种无线、低功耗的心电检测设备,目的是降低功耗、降低成本、便于组网给监护中心提供实时心电信号,以便能实时检测,降低死亡率而被广泛应用。针对人体的生理特点,并考虑到外部条件以及处理器CC2431的特点,对心电信号提出新的采集结构,建立起系统的各部分模块,利用multisim等相关仿真软件对其进行检验,尽可能地提高电路的可靠性。
