摘要
针对近年来安全事件频出,威胁女性单独出行时的安全,设计一种基于嵌入单片机和GPRS无线传输技术的防身报警系统。该系统以STM32嵌入式单片机为控制器,通过摄像头获取环境信息、GPS/北斗双模模块获取位置信息,利用GPRS无线传输模块向紧急联系人发送求助信息并发送遇险人位置,帮助遇险人员在遇险时及时无声告知外界自身的情况。根据试验结果表明,该系统可实现位置实时跟踪和求救短信发送,具有设计小巧、成本低、定位精准等优点。
In recent years,the frequent security incidents,threats to the safety of women traveling alone.A self-defense alarm system based on embedded MCU and GPRS wireless transmission technology was designed.The system uses STM32 embedded MCU as the controller,obtains the environmental information through the camera,obtains the position information through the GPS/BEIDOU double module,uses the GPRS wireless transmission module to send the help information to the emergency contact person and sends the person in distress the position,help the person in distress to inform the outside world of his or her situation in a timely and silent manner.The experimental results show that the system can realize the real-time tracking of position and the sending of short message for rescue.The alarm device has the advantages of small design,low cost,accurate positioning and so on.
