【摘要】 针对公路运输车辆载荷质量的检测采用的计量器具体积大、工作位置固定、不能做到随时随地检测载荷质量的问题,提出一种采用变极距电容传感器的车载式载荷检测装置,该装置中的加速度传感器用于测量前进方向的加速度和竖直方向的加速度。通过实验测试及分析表明,加速度在车辆称重测量中的影响比较大,因此在装置的软件部分必须予以补偿。更多还原

【Abstract】 Aimming to large measurement system used to measure the load of vehicles travelling on highways are fixed and hence unable to measure vehicle-load at ang time and inany place,this paper presents an on-vehicle measure device, which is based on measurement of change in capacitance due to variation in distance between electrodes mounted on vehicle.Acceleration transducers are used to measure the vehicle’s forward and the vertical accelerations.A feature of this on-vehicle measuring device is that it can provide both static and dynamic load measurement.It is concluded that acceleration has a big effect on the vehicle-load measurement and software compensation is needed.更多还原
