Embodiment 1

[0025] like figure 1 Shown is the arrangement scheme of the conjoined platform weighing device of this embodiment. Wherein, the weighing platform 101 and the weighing platform 102 are hinged by using the hinge 103 to form an articulated weighing platform for carrying the vehicle to be weighed. The center distance between the weighing platform 101 and the weighing platform 102 is about 800mm.

[0026] Load cells ( 104 a and 104 b , 105 a and 105 b ) are arranged on the fulcrums of the four corners of the weighing platform 101 . Load cells ( 106 a and 106 b ) are arranged on the fulcrums of the two corners on one side of the weighing platform 102 . Wherein, sensor 104a is connected with sensor 104b to form a first group of sensors, sensor 105a is connected to sensor 105b to form a second group of sensors, and sensor 106a is connected to sensor 106b to form a third group of sensors.

[0027] The weighing platform 101 is fixed and supported by the fulcrums located at its four c...

Embodiment 2

[0035] like image 3 As shown, the vehicle dynamic weighing device of this embodiment includes: two weighing platforms connected to each other, used to carry the vehicles to be weighed passing by; three groups of load cells are respectively arranged on the two weighing platforms, It is used to collect the axle load signal of each axle of the vehicle being weighed; the weighing data processor is used to receive the axle load signal and generate the axle load data of the vehicle under test according to the axle load signal; the external data interface or display screen is used for Output the said axle load data.

[0036] The two weighing platforms are rectangular, and the two weighing platforms are hinged.

[0037] Set two sets of load cells on one of the two weighing platforms, and set a set of load cells on the other of the two weighing platforms; the weighing data processor obtains two sets of load cells respectively. The axle load signals of each axle of the vehicle being ...

Abstract

The invention provides a dynamic weighing method of vehicle and an apparatus thereof. The apparatus comprises: two blocks of weighing platforms, wherein the platforms are connected mutually and are used for bearing a passing vehicle that is weighted; at least two sets of weighing sensors, which are respectively arranged on the two weighing platforms and are used for collecting axle-load signals of all axles of the weighted vehicle; and a weighing data processor, which is used for receiving the axle-load signals and generating axle-load data of the weighted vehicle according to the axle-load signals. According to the invention, the weighing measurement enables data bulk of a characterized driving state to be satisfied; meanwhile, an identification problem of a vehicle driving state of a measured vehicle can be solved, wherein the vehicle driving state includes backup, so that weighing precision is improved.

Description

technical field [0001] The present invention relates to the vehicle weighing technology, especially the vehicle dynamic weighing technology used on highways and other roads, specifically a vehicle dynamic weighing method and device. Background technique [0002] At present, the vehicle dynamic weighing system is widely used in the weighing system of expressways, mines and ports, etc., and plays an important role in traffic management, over-limit and overload control, and import and export supervision. [0003] In the prior art, the weighing platform of the vehicle dynamic weighing system adopts a single weighing platform with a surface width of about 0.8m. The disadvantages of this single weighing platform vehicle dynamic weighing system are: [0004] (1) Due to the limitation of the width of the weighing platform, even when the vehicle under test is running at a low speed, it is difficult for the data collected by the vehicle dynamic weighing system to fully characterize th...
