The invention relates to a vehicle height limit detection early warning system and a working method of the early warning system. The vehicle height limit detection early warning system warns an over-height vehicle, and the license plate number of the over-height vehicle is displayed on an LED display screen in the advancing direction of the vehicle; the system comprises two sets of ultrasonic distance measuring sensors, two sets of license plate recognition cameras, a central data processor, two sets of LED display screens, two sets of stand columns and a power source, and the two sets of stand columns are provided with the two sets of ultrasonic distance measuring sensors and the two sets of license plate recognition cameras respectively. The two sets of ultrasonic distance measuring sensors are arranged in the vehicle coming directions of two directions away from a height-limited building by a certain distance respectively, and the central data processor is installed in a distribution box on a stand column and collects signals of the ultrasonic distance measuring sensors in real time. Whether the over-height vehicle passes on a height-limited road section or not is detected, once the over-height vehicle is found, the camera is immediately triggered to photograph and recognize a license plate, and the license plate is displayed on the front LED screen to warn the vehicle to detour, so that a rear height-limited building is protected.
本发明涉及一种车辆限高检测预警系统和预警系统的工作方法,该车辆限高检测预警系统警示超高车辆,将超高车辆的车牌号显示在车前进方向的LED显示屏上,包括两套超声波测距传感器、两套车牌识别摄像头、中央数据处理器、两套LED显示屏、两套立柱、电源,两套立柱上分别安装两套超声波测距传感器和两套车牌识别摄像头,两套超声波测距传感器分别设置在离限高建筑一定距离的两个方向的来车方向上,中央数据处理器安装在立柱上的配电箱内,实时采集超声波测距传感器的信号。本发明在限高路段上检测是否有超高车辆经过,一旦发现则立即触发摄像头拍照识别车牌,并在前方LED屏上显示该车牌,警示车辆绕道而行,从而保护后方限高建筑。
