The invention relates to a vehicle intelligent height limit early warning method and system. The method comprises the steps that a first terminal controls a laser correlation grating to emit infrared laser to a running vehicle in real time and receives a feedback signal; the first terminal judges that the running vehicle is over-high according to the feedback signal, sends first voice prompt information to the running vehicle by using a directional sound wave technology, controls the camera to collect a running vehicle image, identifies running vehicle data according to the running vehicle image, and sends the data to the server; and the running vehicle data are sent to a second terminal through the Lora communication technology to be displayed on a display screen, and second voice prompt information is sent to the running vehicle through the directional sound wave technology. The first terminal can quickly control the camera to capture the over-height vehicle and send out the first voice prompt information according to the feedback signal, so that early warning is carried out at the first time, and the precision of height limit early warning is improved; and display can be performed through the display screen, so that the early warning prompt effect is enhanced, and the occurrence rate of traffic accidents caused by height exceeding is greatly reduced.
本方案涉及一种车辆智能限高预警方法及系统。所述方法包括:第一终端控制激光对射光栅实时向运行车辆发射红外激光,并接收反馈信号;第一终端根据反馈信号判断运行车辆超高,则利用定向声波技术向运行车辆发送第一语音提示信息,并控制摄像头采集运行车辆图像,根据运行车辆图像识别出运行车辆数据,通过Lora通信技术将运行车辆数据发送至第二终端在显示屏进行显示,并利用定向声波技术向运行车辆发送第二语音提示信息。第一终端根据反馈信号可以快速控制摄像头抓拍超高车辆并发出第一语音提示信息,从而第一时间进行预警,提高限高预警的精度;还可以通过显示屏进行显示,加强预警提示作用,大大降低因超高引起的交通事故发生率。
