The weighing sensor signals collected at the front end are converged into a weighing controller, and the weighing controller processes the signals according to a two-stage division scheme of a preset weighing area. The device is schematically shown in FIG. 1.
The two-stage division scheme of the weighing area is as follows:
pre-combination division of a weighing area, presetting a combination scheme aiming at the width of a road surface and the width of a lane which are installed on the spot, configuring a weighing platform and a sensor, determining the boundary condition of the pre-combination scheme as a first-stage combination, and dynamically adjusting and dividing the boundary condition of the pre-combination scheme as the boundary condition of a dynamic self-adaptive scheme in a limited interval. Such as the maximum number of dynamic adjustment units.
As shown in fig. 2, first, it is determined that the area 0 is a boundary area of the present scheme, and all weighing areas should be divided not to exceed the area 0. Then, the area 1, the area 2 and the area 3 are determined as weighing areas of the lanes according to the number of the lanes.

When the single lane is weighed, the vehicle covers the corresponding single lane weighing area, and the weighing basic unit combination scheme is limited to the combination of a plurality of minimum weighing units in the single lane area. When weighing across lanes, the vehicle will cover the corresponding adjacent lane weighing area. The weighing basic unit combination scheme is to combine a plurality of minimum weighing units in corresponding adjacent lanes. See fig. 3, 4.
