摘要
针对目前老人出行安全的问题,设计一款在老人出现意外状况时能及时呼救和报警的智能拐杖。设计以STM32单片机为控制核心,结合当前先进的成熟的信号处理算法、传感器技术、无线通信技术,采用MPU6050水平检测模块实时测量拐杖与地面的倾角,在出现突发情况时通过语音模块识别求救,GPS模块实现定位功能,以信息的方式发送给监护人。此外,系统还能显示温湿度、PM2.5浓度等环境信息。测试结果表明,整个系统性能稳定,灵敏度高,操作方便,并且功能易于扩展,满足老年人出行多方面需求。
Aiming at the problem of safety for the elderly, a smart crutch is designed which can call for help and call the po-lice in time when an accident occurs. The design takes STM32 microcontroller as the control core, combines the current advancedsignal processing algorithm, sensor technology, wireless communication technology, and adopts the MPU6050 horizontal detection mod-ule to measure the angle between crutches and the ground in real time. In case of emergency, the GPS module realizes the position-ing function through the voice module identification and call for help GPS module, and sends the information to the guardian in theway of information. In addition, the system can also display temperature and humidity, PM2.5 concentration and other environmentalinformation. The test results show that the whole system has the advantages of stable performance, high sensitivity, convenient opera-tion, and easy expansion of functions to meet the needs of the elderly in many aspects of travel.
