【摘要】 设计了基于应变式称重传感器的车辆行驶称重系统,包括应变式称重传感器的结构特点、动态特性、信号采集放大与模/数转换的硬件结构,以及基于采样平均法的信号处理精度和传感器间距的设计表达式。该称重系统在公路车辆限速行驶状态下,能测出行驶车辆的静态质量、行驶速度以及轴距等车辆静态参数。更多还原

【Abstract】 The weigh-in-motion system of vehicle,including the structure and dynamic characters of the strain sensors,the hardware structure of signal sampling-amplifying and A/D transformation and the precision & sensor space design expression of sample mean approach was designed. The system can measure the static parameters of vehicles, such as static weight,velocity and axle space, provided that the velocity is restrained.更多还原
