基于物联网的自动报警智能拐杖系统的设计

Design of an automatic alarm walking stick system based on Internet of things

随着社会事件的发生,老人安全出行再次引发人们的重点关注。一种基于物联网能实现自动报警的智能拐杖能够保障老人安全出行,拐杖系统包括数据采集与数据处理的拐杖终端。该系统利用ADXL345三轴加速度传感器测量倾角精度高,SIM908模块集GPS单元与GSM单元于一体的特点,可准确获得老人行走状态并进行判断、处理。实验结果证明,该系统可实现定位、摔倒判断、自动报警、通信等功能,克服了目前国内相关产品只能手动报警的缺陷,可为老人安全出行提供保障。

Safety for the old is a matter of considerable interest .It is a design of intelligent walking stick system which can realize automatic alarm based on Internet of things .Data sampling and data processing are included in the walking stick terminal .The system takes good use of which ADXL345 acceleration sensor has the advantage in measuring angles with high precision and SIM 908 integrates GPS and GSM to get accurate condition of the old ,then decide and take actions . It overcomes the shortage that related domestic products currently can only ask for help manually . Experiment proofs the system can get positions ,detect falling down ,communication and alarm automatically .It is a method to providing security for the elderly .
