摘要
实现了在无线体域网中对体温、脉搏和血氧饱和度等体征参数的采集与处理。选择数字温度传感器DS18B20完成对人体体温参数的采集,并使用双光束透射法对脉搏、血氧饱和度进行无创检测,而后通过蓝牙实现数据的无线传输。设计以小型化、低功耗为原则,通过数字信号处理技术完成一系列工作。实验结果表明设计方案具有很高的稳定性和可靠性。
A design aiming at samplig and processing healthy parameters in WBAN is discussed. Digital thermometer DS18B20 is selected to get the body temperature,and non-invasive dual-ray method is used to detect the pulse and oxygen saturation,then data wireless transmission is realized through Bluetooth.Based on the simple construction and low-power consumption,the digital signal processing methods are adopted to complete a series of work. By testing,a good performance is achieved to show the design has a high stability and reliability.
