基于物联网的多功能防身报警器

Design of multifunctional self-defense alarm based on Internet of things

为提高相对弱势群体人身安全的保障,设计了一款以STM32单片机为控制核心的多功能防身报警器。使用c语言编程,进行电路模块化设计。采用主控制器模块、GSM模块、GPS模块、报警模块、按键模块和蓝牙模块等,在紧急情况下为用户提供警鸣、短信求助联系紧急联系人等服务。操作简便,增强了使用者的人身安全保障。

In order to improve the security of the vulnerable groups,a multifunctional personal alarm based on single chip microcomputer STM32 was designed.C language was used for programming and modular circuit design.The main controller module,GSM,GPS,alarm,key and Bluetooth module are adopted to provide users with alarm sound,short message and contact services in emergency situations.It is easy to operate,enhance the user’s personal safety protection.
