摘　　要：针对传统独居老人监护系统过于依赖摄像头等设备的缺点,提出了一种物联网和超声波传感器技术相融合的独居老人监护系统。使用MSP430F5438单片机、TDC-GP22高精度时间测量芯片和nFR24L01无线射频芯片设计了一款基于时差法的超声波流量计,用水数据通过nFR24L01模块进行无线传输至NLECloud云平台,通过递推算法预测老人用水量,并且给出异常处理。研究结果表明,通过实时准确监测与预测用水量,为独居老人的生活提供安全保障,同时也最大程度保护了独居老人的隐私。In contrast to the traditional monitoring system,which relies on cameras heavily,a new design is proposed by applying internet of things and ultrasonic sending technology.Combining microcontroller MSP430F5438,high-precision interval measuring chip TDC-GP22 and radio-frequency chip nFR24L01,a flowmeter is made based on TDOA(Time Difference of Arrival).Water consumption data is uploaded to NLECloud through nFR24L01 wireless module,which will be analyzed with recursive algorithm to generate alarm.With this study,by monitoring water consumption in real time and predict future usage,the health and safety of elderly living alone can be ensured,in addition,elderly's privacy can be guaranteed at the same time.
