The invention relates to a method for identifying an overweight vehicle on a bridge, and relates to the field of bridge monitoring, management and maintenance. The method comprises the steps: collecting stress values of corresponding bridge beams when vehicles pass through a monitoring device; if the stress value is greater than a preset stress value, calculating a first weight W1 and a second weight W2 of the vehicle passing through the monitoring device according to an area method and a peak value method; determining the final weight W of the vehicle based on W1 and W2, and if W is larger than the preset weight, calculating the running speed V of the vehicle passing through the bridge, if the running speed V is smaller than the preset speed, calculating the time range of the vehicle entering the visual field of the camera, judging whether a large truck passes or not by monitoring video information passing through the camera within the time range, and if yes, it is judged that the vehicle is an overweight vehicle. According to the method for identifying the overweight vehicle on the bridge, the problems of high equipment cost, high installation process difficulty and low accuracycaused by single identification standard in the prior art are solved.
本申请涉及一种识别桥梁上超重车辆的方法,涉及桥梁监测管养领域。本方法包括通过监测装置采集车辆经过时对应桥梁处的应力值,若该应力值大于预设应力值,再根据面积法和峰值法计算经过监测装置的车辆的第一重量W1和第二重量W2,基于W1和W2确定该车辆的最终重量W,若W大于预设重量,再计算车辆通过桥梁时的行驶速度V,若该行驶速度V小于预设速度,再计算车辆将进入摄像头视野的时间范围,并通过监测时间范围内经过摄像头的视频信息判断是否有大型货车通过,若有,则判定该车辆为超重车辆。本申请提供的识别桥梁上超重车辆的方法,解决了相关技术中存在设备成本高、安装过程难度大、识别标准单一造成准确率低的问题。
