摘要
目前我国对重车收费大多采用静态称重,人工收费,少数地区虽采用动态称重,但称重精度较低,所以汽车只能低速通过,由此导致通行效率低,收费站大面积拥堵,其中最主要的原因在于:现有动态汽车衡无法在重车高速行驶或不规范行驶时保证其称重精度。为此,本文通过研究传感器的性能以及布局和动态称重精度的关系,利用计算机建模和实地测试相结合的方法,对不停车计重收费(EWTC)系统进行优化,使重车以30km/h通过动态汽车衡误差在±1.5以内。
At present, most of the heavy vehicles in China adopt static weighing, manual charging. A small number of regions use dynamic weighing, but the weighing accuracy is low, so the cars can only pass at low speed. This leads to low pass efficiency and large congestion of the toll station. The most important reason is that the existing dynamic truck scale can not ensure the weighing accuracy of heavy truck with high speed or irregular travel. To this end, through the study of the sensor＇s performance and the relationship between the layout and dynamic weighing accuracy, this paper uses computer modeling and field testing methods to optimize EWTC system to make the error in ±1.5 of the heavy car passing the dynamic automobile scale with the speed of 30km/h.
