A daily living activity remote monitoring system has been developed for supporting solitary elderly people. The monitoring system consists of a tri-axis accelerometer, six low-power active filters, a low-power 8-bit microcontroller (MC), a 1GB SD memory card (SDMC) and a 2.4 GHz low transmitting power mobile phone (PHS). The tri-axis accelerometer attached to the subject's chest can simultaneously measure dynamic and static acceleration forces produced by heart sound, respiration, posture and behavior. The heart rate, respiration rate, activity, posture and behavior are detected from the dynamic and static acceleration forces. These data are stored in the SD. The MC sends the data to the server computer every hour. The server computer stores the data and makes a graphic chart from the data. When the caregiver calls from his/her mobile phone to the server computer, the server computer sends the graphical chart via the PHS. The caregiver's mobile phone displays the chart to the monitor graphically.
为了帮助独居老人,开发了一种日常生活活动远程监测系统。该监测系统由一个三轴加速度计、六个低功耗有源滤波器、一个低功耗8位微控制器(MC)、一个1GB的安全数字存储卡(SDMC)和一部2.4GHz低发射功率移动电话(PHS)组成。附着在受试者胸部的三轴加速度计可以同时测量由心音、呼吸、姿势和行为产生的动态和静态加速度力。从动态和静态加速度力中检测心率、呼吸率、活动、姿势和行为。这些数据存储在SD卡中。微控制器每小时将数据发送到服务器计算机。服务器计算机存储数据并根据数据制作图表。当护理人员从他/她的手机呼叫服务器计算机时,服务器计算机通过PHS发送图表。护理人员的手机将图表以图形方式显示在显示器上。
