跌倒是老年人中的一个严重问题;它会导致严重的伤害和后果。跌倒后不能移动意味着受试者不能自己寻求帮助，这会显著增加跌倒引起的伤害的百分比。本文的目的是设计和实现一个跌倒检测和报警系统的老年人。它旨在通过在他们和护理人员之间进行按需或自动通信来促进跌倒后的帮助。该系统由一个可穿戴监测设备组成。该设备能够准确区分老年人的福尔斯和非福尔斯，然后通过使用现有的成熟技术（GPS、GSM/GPRS），提醒他们的护理人员。在检测到跌倒时，包含加速度计传感器、GPS接收器、处理单元和GSM模块的嵌入式系统发送警告消息，警告其他人沿着其方位发生了跌倒。此外，该设备能够通过在用户越过预定义的阈值距离时发送包含其位置（纬度和经度坐标）的SMS来提醒护理人员用户已经离开他的位置。开发的原型进行了评估，并表现出令人满意的性能。
Falling is a serious issue among old aged population; it leads to severe injuries and consequences. Inability to move after a fall means that the subject cannot ask for help by himself, which increases the percentage of fall-induced injuries significantly. The objective of this paper is to design and to implement a fall detection and alert system for the elderly persons. It aims to facilitate the help after a fall, by featuring on-demand or automatic communication between them and caregivers. The system consists of a wearable monitoring device. The device is able to accurately distinguish falls from non-falls of elderly persons and then, by using existing proven technologies (GPS, GSM/GPRS), alerts their caregivers. Upon detecting a fall, the embedded system encompassing the accelerometer sensor, the GPS receiver, the processing unit and the GSM module send a warning message alerting others that a fall occurred along with its orientation. In addition, the device is able to alert caregivers that the user has left his place by sending an SMS containing his location (latitude and longitude coordinates) as soon as he crosses a predefined threshold distance. The developed prototype was evaluated and showed satisfactory performance.
