摘要
为避免因司机的大意和路况不熟造成的违规停车问题,营造更好的交通秩序,文中基于单片机设计了一种辅助停车预警系统。系统采用raspberry pi 4B作为控制中心,将OpenCV算法、北斗卫星定位、WiFi通信、物联网平台与微信小程序相结合,以实现对路边禁停标识的识别和对驾车人的智能预警,并具有行车数据云储存、手机小程序端智能语音提醒、经停轨迹查看等功能。该系统实现了在raspberry pi 4B上的正确识别显示、OneNET平台上的后台显示以及手机端微信小程序的显示和语音提醒。运行结果显示,在理想的路况下,对禁停标识达到了80%的识别效果,并能将数据实时上传至OneNET云端,微信小程序中也可正确地进行语音预警和查看有禁停趋向的地点信息,具有成本低、使用便捷、扩展方便等优点,具有较高的商业价值和社会意义.
In order to avoid illegal parking problems caused by the driver’s carelessness and unfamiliar road conditions,and create a better traffic order,this system designs an auxiliary parking early warning system based on a single-chip microcomputer.The system uses raspberry pi 4B as the control center,and combines OpenCV algorithm,Beidou satellite positioning,WiFi communication,Internet of Things platform and WeChat applet to realize the identification and intelligent warning of drivers,and it has driving data in cloud storage,intelligent voice reminders on the mobile phone applet,and viewing of transit trajectories. This system realizes the correct recognition display on the raspberry pi 4B,the background display on the OneNET platform,the display of the WeChat applet on the mobile phone and the voice reminder. The operation results show that under ideal road conditions,80% of the recognition effect of the prohibition signs is achieved,and the data can be uploaded to the OneNET cloud in real time. The WeChat applet can also correctly perform voice warnings and view the locations with prohibition parking.The systerm has the advantages of low cost,convenient use,convenient expansion,etc.,and has high commercial value and social significance.
