s101, acquiring actual attributes and state information of the overweight vehicle to be detected before passing through a bridge, wherein the actual attributes and state information comprise position, speed, acceleration, braking distance, total weight, load distribution, wheel track, axle number, wheel number and overall dimension.
The load distribution includes but is not limited to linear distribution load, surface load and body load. The wheel base refers to the distance measured on the supporting surface between the tire symmetry planes of the left and right wheels on the same axis; when two wheels (two tires on the same side of a single shaft) are used, the distance between the symmetrical planes of the left and right wheels measured on the supporting surface is referred to. The number of wheels refers to the total number of wheels of the vehicle. The overall dimension can be expressed by length, width and height.
The total weight here refers to the weight of the overweight vehicle itself plus the weight of the transported goods.
