基于物联网技术的病残老人穿戴装置设计和制作

摘要

为了家庭病房和病残老人户外活动遇到意外情况时能够得到及时救治,设计并制作了一款基于物联网技术的穿戴装置.首先简单介绍了系统方案.然后,介绍了穿戴装置的硬件组成和连接方式.详细介绍了穿戴装置的监控程序、定时中断程序、以及通信程序的设计思路和流程.测试结果表明设计制作的基于物联网技术的穿戴装置能够实时测量携带人的心电、体温等信息;能够向家人发出求救短信,向医院发送体征信息,以及向路人发出求助信号和救助指示.%In order to get aided or cured in time while disabled people encounter accident outdoor or in home alone,a wearable device based on the Internet of Things (IOT) is researched in this paper.Firstly,the system scheme is introduced briefly.Then,the hardware composition and structure are described.Those flow charts of monitor routine,timer interrupt routine, and communication routines are presented in succession.
