The invention discloses a multi-lane bridge vehicle passing information and vehicle weight identification method and system, and relates to the technical field of vehicle weighing, and the method comprises the steps: employing a standard weight vehicle to independently drive on each lane of a bridge for calibration, and obtaining the geomagnetic response and dynamic strain response in each calibration process, obtaining a bridge multi-lane response matrix; the vehicle passing information of each lane of the bridge is calculated by matching the sensing wave crest characteristics when the vehicle passes through the plurality of geomagnetic sensors; based on a non-negative matrix factorization algorithm, in combination with the bridge multi-lane response matrix and the bridge real-time multi-lane dynamic strain response vector, obtaining a multi-lane vehicle weight distribution ratio and a target vehicle weight; and when the vehicle weight of the target vehicle is greater than the preset weight, transmitting the vehicle information of the target vehicle to a background server in real time. According to the invention, vehicle passing condition identification and vehicle weight calculation under the complex vehicle passing condition of the whole deck of the multi-lane bridge can be realized, and all-weather identification of the vehicle passing condition is realized.

    本发明公开了一种多车道桥梁车辆通行信息与车重识别方法及系统,涉及车辆称重技术领域,该方法包括采用标准重量车辆在桥梁各车道上单独行驶以进行标定,并获取每次标定过程中的地磁响应和动应变响应,得到桥梁多车道响应矩阵;通过匹配车辆通过多个地磁传感器时的感应波峰特征,解算得到桥梁各车道的车辆通行信息;基于非负矩阵分解算法,并结合桥梁多车道响应矩阵和桥梁实时多车道动应变响应向量,得到多车道车重分配比和目标车辆车重;当目标车辆的车重大于预设重量时,将目标车辆的车辆信息实时传输至后台服务器。本发明能够实现了多车道桥梁全桥面复杂车辆通行状况下的车辆通行状况识别与车重解算,实现车辆通行状况全天候识别。
