Abstract
With the improvement of human life quality, life expectancy generally increases. As a result, more and more elderly people living alone appear. Recently, the safety problems of the elderly living alone have attracted more and more attention from the public. Due to living alone, the elderly cannot be found at the first time when an accident occurs indoors or out, and the rescue time is delayed. This article proposes a way to use the speed up module to realize real-time face detection on the Raspberry Pi and optimize the processing of PIR sensor signals and write a logic system based on the camera and PIR signals to record and analyze the life of the elderly living alone and warning system to their family members.
随着人类生活质量的提高，预期寿命普遍延长。因此，出现了越来越多的独居老人。近来，独居老人的安全问题越来越受到社会各界的关注。由于独居，当老人在室内外发生意外时，无法第一时间发现，延误了救援时间。本文提出了一种在树莓派（Raspberry Pi）上使用加速模块实现实时人脸检测的方法，并优化了 PIR 传感器信号的处理，编写了基于摄像头和 PIR 信号的逻辑系统，对独居老人的生活进行记录和分析，并向其家人发出预警系统。
