摘要
电动轮椅可以让老年人远距离出行,但是监护人不一定能时刻跟随照顾,针对这一问题设计了一种电动轮椅户外监测系统。通过硬件电路集成和控制与通讯程序编写来实现轮椅定位信息,乘坐信息,轮椅电量信息等数据实时上传OneNet云平台,监护人可在Web和APP端随时随地查看轮椅乘坐状态和位置信息。系统选用STM32F103作为控制的核心芯片,GPS/GSM模块作为定位和数据上传的核心硬件,薄膜压力传感器和加速度陀螺仪传感器作为安全检测模块,轮椅上还集成了紧急报警按钮和语音播报模块,在老人遇到危险的时候可以一键拨打电话联系监护人,语音模块还可提供安全坐姿提醒和低电量报警。
Electric wheelchair can let old people long-distance travel,but the guardian can not moment with care,in order to solve this problem an electric wheelchair outdoor monitoring system is designed.Through the hardware circuit integration and the control and communication program,the wheelchair positioning information,ride information,wheelchair power information and other data can be uploaded to the ONENET cloud platform in real time.Guardians can check the wheelchair riding status and location information on the Web and APP terminals anytime and anywhere.System chooses STM32F103 as control core chip,GPS/GSM module,which is the core of the positioning and data upload hardware,thin film pressure sensor and acceleration gyroscope sensor as a security detection module,the wheelchair has integrated the emergency alarm button and speech module,when the old man in danger can call contact the guardian,a key voice module can also provide security posture to remind and low battery alarm.
