摘要/Abstract

摘要： 介绍了一种以射频芯片nRF24L01为无线通信核心的无线心音遥测系统的实现方案。整个系统通过8位单片机STC12C5A60S2来控制。STC12C5A60S2内部的10位ADC可以对放大滤波后的心音信号进行采集,再写入nRF24L01进行无线传输,接收端由单片机通过nRF24L01接收数据,再由UART通过串口将其传输到PC机进行显示与分析。经测试,该系统在室内通信良好,所显示的心音波形满足要求。此外就各模块的通信协议以及对应的程序也进行了具体分析。

Abstract: This paper introduced the design of a wireless PCG monitor based on nRF24L01．The controller is STC12C5A60S2with a 8bit MCU．10bit ADC in STC12C5A60S2is used to convert the PCG signal which has been out of the amplifier and filter．The data will be writen in the memory of nRF24L01and be transmitted．The receiver takes the data and sends them to computer for display and analysis．The result of testing shows that the indoor communication is well and waveform of PCG meets the requirements．In addition,the communication protocol and the program were also analyzed.
