基于双通道无线心电监护终端设计

Development of a based on dual channels portable ECG monitor terminal

随着无线通讯技术的发展,本文提出一种新的基于GPRS和CDMA双通道的便携式心电实时监护终端。通过在ARM7处理器LPC2148上移植μC/OS-II嵌入式操作系统,该监护终端实现了三导联心电数据的采集和实时处理。对比同类无线监护终端,该终端采用双通道通信,保证了网络信号微弱时,心电数据的传输和备份。本文将对该终端实现原理进行深入讨论,同时介绍该监护终端的软硬件架构。

With the development of the wireless communication technique, a portable remote ECG real-time monitor based on GPRS and CDMA dual channels is introduced. By integrating ARM7 microprocessor LPC2148 with μC/OS-Ⅱ, the monitor realized threelead ECG signal acquisition and real-time processing. Compared with other similar device, this terminal with dual channels can imp/ement effective data backup, when the wireless network doesn＇t work. The principle of above system and system realization process were introduced, and the chief frameworks of hardware and software structure were put forward in this paper.
