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 provide security for the elderly living alone, it is necessary to design a wireless attitude detection system to detect the safety of the elderly. Here combined with micro-sensors, embedded microcontroller and wireless short-range communication technology, a human posture detection system design. The test results show that the system can distinguish the normal human activities and fall events in the human body wearing test and automatically send the fall alarm signal so that the user can get the medical aid in the shortest possible time.
