摘要
针对社会中的老人群体,该文从实际应用角度出发,提出了基于Cortex-M4的便携式求救仪设计方法。仪器采用以Cortex-M4为内核的STM32F407单片机控制GSM模块发送求救短信,并利用GPS技术实现对用户的位置定位。解决了老人独自在家或行走在外时,突发险情,难以及时求救的问题。该仪器已得到成功应用,经实践表明,其可靠性很强且操作简单。
For the old of the social group,this article from the perspective of practical application,puts forward a de- sign scheme which is based on the design of portable instrument based on the Cortex-M4 kernel. The instrument use STM32F407 microcontroller,which put Cortex-M4 as kernel to control the GSM module to send distress mes- sage,and use GPS technology to learn about the user＇s local position. It has solved the problem that the old man is difficult to for help in time when they stay alone at home or walking alone at outside,they confront the sudden dan- ger. The instrument has been applied successfully,tbe practice shows that its reliability is very strong and its opera- tion is very simple.
