基于MSP430F247嵌入式单片机无线心电监护系统的网络传输

Wireless net electrocardiogram monitor system based on MSP430F247 embedded MCU

介绍了一种基于嵌入式单片机和通用分组无线服务的心电监护仪设计。包括硬件设计和软件设计两个部分:硬件设计部分着重介绍了心电调理模块(放大与滤波,50Hz工频干扰消除),采集存储模块以及液晶显示模块和通用分组无线服务模块;软件设计部分着重介绍软件总体设计和液晶动态显示软件流程,同时给出了部分通用分组无线服务模块软件设计程序。整个系统以MSP430F247单片机为核心,包括心电信号的采集,存储和显示;以及心率计算,报警设置,有线和无线两种网络传输方式。该系统具有功耗低,便于携带,监护时间长,网络化、实时采集和传输等优点,作为家庭医疗和社区医疗的心电监护具有较大的实际意义。

A new method of designing a wireless electrocardiogram （ECG） monitor which based on embedded MCU and general packet radio service （GPRS） is introduced. The design includes two parts： hardware and software. The hardware circuit contains ECG conditioning circuit module （amplifying circuit, filtering circuit and trap circuit of 50 Hz）, sample and memory circuit module, display circuit of LCD and GPRS communication module. And the software includes overview chart, LCD dynamic display chart and the procedure of GPRS. Simultaneously, it takes MSP430F247 as the core of controller and consists of ECG collection, storage, and display. Also it has the arithmetic of heart rate, and warning equipment. The communication of wire and wireless are designed. The system is characterized by low-power, portable, long monitoring time, and a wide range of wireless network coverage. This application is optimum in the fields of home health care and community medical care.
