摘要
针对近年来安全事件频出,现有安全防护产品存在易误伤等问题,文中设计了一种基于OneNET平台的远程防身报警器。该系统以STM32嵌入式单片机为控制器,通过摄像头和GPS/北斗双模模块获取环境与位置信息;利用GPRS无线传输模块将遇险人位置地图在OneNET云平台上显示,并将遇险人的求救信号和位置信息发送给紧急联系人,帮助遇险人员及时无声向外界求助;同时现场发出强光和高分贝报警为遇险人提供帮助和脱险机会。试验结果表明,该系统可实现位置实时准确跟踪和求救短信发送,具有一定的实用价值。
Based on the frequent safety incidents in recent years,and the problem of easy accidental injury of current safety protection products,this paper designs a remote self-defense alarm based on OneNET platform.The system uses STM32 embedded microcontroller as the controller to obtain the environment and position information through the camera and the GPS/beidou module,and uses the GPRS wireless transmission module to display the distress person s position map on the OneNET cloud platform.Then,the distress signal and the location information of the person in distress are sent to the emergency contact person who can help the person in distress to seek help from the outside world in time and silently.Meanwhile,the strong light and high decibel alarm will help the person in distress to escape from danger.The experiment results show that the system can realize the real-time accurate tracking of position and the sending of short message for rescue,which proves certain practical value.
