摘要
通过设计电荷放大、低通滤波及电压放大电路,对动态称重传感器采集的数据进行处理,得到车速、轴数、轴重等车辆参数,通过4G网络传输至服务器。然后进行路面模拟测试和高速公路现场实测,试验结果表明,系统可以实时采集道路轴载谱并上传至服务器。
By designing charge amplifying,low-pass filtering and voltage amplifying circuits,the data collected by the dynamic load cell is processed to obtain vehicle parameters such as vehicle speed,axle number,axle weight,etc.,which are transmitted to the server through the 4G network.Road surface simulation tests and highway field tests are conducted.The test results show that the system can collect the road axle load spectrum in real-time and upload it to the server.
