摘要
脉率是重要的人体生命特征之一。文章基于nRF2401的脉率监测系统设计了病床到病房、病房到护士站两层无线传输系统。该系统通过光电传感器CT188采集病人食指末端的脉搏变化信号;通过滤波和计算得到相应的脉率信息;通过nRF2401无线网络将相关数据在病房大屏显示;通过串口将数据送到护士端电脑,为后续病情诊断提供数据。该系统传输稳定,可以降低护士的工作量,提高工作效率。
Pulse rate is one of the important human life characteristics.The pulse rate monitoring system based on nRF2401 designs two-layer wireless transmission systems from hospital bed to ward and from ward to nurse station.The pulse change signal at the end of the patient’s index finger is collected through the photoelectric sensor ct188,the corresponding pulse rate information is obtained through filtering and calculation,and the relevant data is displayed on the large screen of the ward through the nRF2401 wireless network.The data is sent to the nurse computer through the serial port to provide data for subsequent disease diagnosis.The system has stable transmission,which can reduce the workload of nurses and improve work efficiency.
