Abstract

A device for weighing vehicles in motion comprises a weighing platform (2) disposed inside of an installation groove of a road surface base (1), the weighing platform surface and the road surface base (1) being on the same level; at least two weighing sensors (5) fixedly disposed on the weighing platform (2) for sensing and transmitting the weight of a vehicle in motion that the weighing platform (2) bears; under the surface of the weighing platform (2) is a sensor chamber (6) disposed along the direction of the vehicle movement; the sensor chamber (6) is disposed with the weighing sensors (5) at the front and the back sides along the vehicle movement direction; no gap exists between the weighing platform (2) and the inner wall of the installation groove of the road surface base (1) along the vehicle movement direction.

Description

technical field [0001] The invention relates to a vehicle dynamic weighing device, which belongs to the technical field of weighing. Background technique [0002] In order to curb overloaded transportation, in recent years, people have set up toll booths at the entrances of expressways, bridges, etc., using weight toll, that is, toll according to the weight of the vehicle when it passes, and the infrastructure for toll by weight is the vehicle weighing device. The vehicle weighing device used in the early days was a static weighing instrument. When this weighing device is used, the vehicle needs to drive to the weighing device first, and the reading can only be displayed accurately after the vehicle is stable on the weighing platform, which leads to weighing speed. It is very slow. In the case of large traffic flow, it often causes many vehicles to wait, resulting in road congestion. [0003] In order to avoid the above-mentioned defects of the static weighing device, a veh...
