| Car-weighting-dynamically System on Freeway plays a important role of protecting freeway to use normally. This article studies how to implement car-weighting dynamically in the situation that the sampling-time is short. The method on the base of pre-experiment knowledge is the kernel method in this article.Firstly, studying the movernental and dynamical features that cars behave in the process of Car-weighting-dynamically, and knowing that the vibrations are the main factors impacting the measure precision. So it is concluded that to reduce and avoid the stochastic vibrations is necessary and useful. Secondly, taking this result as the pre-experiment knowledge to guide the construction of the experiment system. Thirdly, finding the post-experiment knowledge well and truly by doing a good many of experiments, and then implementing compensating-arithmetic-dynamically on the basic of the post-experiment knowledge. Finally, putting forward the conception of æšroportional Maximal Value?PMV), and then seeking after the quantitative relation between PMV and static axle-load.Besides, this article studied how to implement the software system, including result-showing, soft operating flat, soft alarming and database implementing. |
