基于物联网的智能呼救系统的设计

The Design of Intelligent Call System Based on Internet of Things

基于物联网的智能呼救系统,采用STM32作为核心主控板,ADXL345加速度传感器对老人的体位进行检测。当老人跌倒时,加速度传感器感受到摔倒时会发出报警声,GPS定位老人地理位置信息,并由STM32对收集到的信息进行处理,GPRS/GSM发送到救护人的手机上,接收到老人的求救信息和老人的地理位置信息。这个设计能够避免老人因为救助不及时而造成的二次伤害,有一定的实际应用价值。

The intelligent call for help system based on the Internet of Things uses STM32 as the core main control board,and detects the position of the elderly through the ADXL345 acceleration sensor.When the old man fell down,the acceleration sensor would make an alarm sound when sensing the falling,located the geographic location information of the old man through GPS,processed the collected information in the STM32,and send it to the mobile phone of the rescued worker through GPRS/GMS to receive the distress information and geographical location information of the old man.This design could avoid the secondary injury caused by the elderly because of the late rescue,and had certain practical application value.
