摘要
介绍了远程心电监护系统中无线信号采集系统软硬件设计的关键技术,该技术实现了对心电信号的采集、滤波以及无线传输等功能,具有便携、低功耗、抗干扰、实时、智能化等特点;系统以MSP430单片机为控制核心,将信号滤波放大后经nRF905无线模块发送至上位机,实验证明能够满足连续监护的要求。
Presents the crucial techniques of hardware and software designing applied to wireless signal sampling device.in electroeardiogram monitoring. This type of device is designed with the functions of sampling, filtering, wireless transmitting, and characterized with portable, low-power, anti-interference, intelligent, etc. The system is controlled by MSP430 singlechip. It filters and amplifies the signal and send data wirelessly, Experiments indicate the system is suitahle for continuous monitoring.
