摘要
为了提供独居老人的安全保障,设计一个无线姿态检测系统用于检测老年人的行动安全是相当必要的。这里结合了微传感器、嵌入式单片机和无线短距离通信等技术,提出一种人体姿态检测系统的设计方案。测试结果表明,该系统在人体佩戴实验中,可以区分出正常人体活动与跌倒事件,自动发出跌倒报警信号,从而使用户在尽可能短的时间内得到医疗救护。
In order to support the elder people＇s safety a posture monitoring system for monitoring the movement of the people is designed.In integration of MCU,tri-axial accelerometer sensor,wireless communication and other technologies,a design scheme for body posture detection system is proposed.The result shows that the posture monitoring system could successfully measure the user＇s gesture and alarm the falling movement.Thus the users could be medically rescued in a short time when they fall down.
