一种便携式智能跌倒检测仪的设计与实现

摘要

In accordance with the situations of population aging problem becomes increasingly prominent and the expanded empty nest phenomenon in our country, in order to avoid the aged people have fallen when unattended, even lead to sudden death because they can not be detected and aided timely, thus the portable intelligent fall detector has been designed and implemented by adopting 3-axis fall algorithm and GPRS wireless communication technology. Through tests, it is shown that the users with wearable sensor can be accurately detected when they fall, and local audible and visible alarm and remote alarm can be issued, the instrument features precise alarm rate and high stability, in addition, it possesses broad marketing prospects and good social benefits.%针对我国日益突出的人口“老龄化”问题以及普遍存在的“空巢”现象，为了避免老人发生跌倒时无人看护，以至于不能及时发现而无法及时获得救助导致猝死等情况的发生，利用三轴跌倒算法和GPRS无线通信技术，设计并实现了一种便携式智能跌倒检测仪。通过测试表明，该跌倒检测仪能对佩戴者是否发生跌倒进行准确检测，并及时准确发出本地声光报警和远程报警，具有报警准确率高、稳定性强等特点，具有广阔的市场前景和良好的社会效益。
