基于物联网的智能手杖的设计

Design of smart walking cane based on IOT

为了让老年人安全出行,通过智能手杖来实时感知其出行情况。针对现有智能手杖的缺陷与功能不足,提出并采用振动与电容传感器、嵌入式微处理器、GPS全球定位、3G无线通信等技术,设计出一款全新的基于物联网的智能手杖。详细阐述其工作原理、系统构成、硬件模块设计与软件设计以及测试结果。实践表明,基于物联网的智能手杖灵敏度高、响应快,能有效判定老人是否摔倒,若老人摔倒,智能手杖自动向周围及家属并发出求助信息,使老人能及时得到救助。

In order to make the old travel safely,it is necessary to perceive the real-time travel situation by smart walkingcane automatically.A new smart walking cane based on Internet of Things(IOT)is proposed to overcome the defects and func-tional deficiency of the traditional walking cane.Some vibration sensors,capacitance sensors,embedded microcontroller,GPS,3G wireless communication and so on are adopted in the new cane.The working principle,system structure,hardware modulesdesign,software design and testing results of the smart walking cane based on IOT are described in detail.The application re-sult shows that the smart walking cane based on IOT has high sensitivity and fast response,and can effectively monitor whetherthe elderly has fallen down.If this happen,the smart walking cane will send out the information for help to passerby and hisfamily members,so that the elderly will get rescued in time.
