Problems solved by technology

However, when there are two containers on the container truck at the same time, only one of the containers can be hoisted and weighed by a special hoisting scale, or one of the containers can be placed on a special weighing scale by a spreader. The weighing device weighs it, which not only causes a large weighing error, but also affects the shipping efficiency
Therefore, when a container truck carries two containers at present, the truck scale cannot judge the physical weight of each container.

Embodiment 1

[0019] Choose Aolong ZZ43226M294, Mitsubishi FV415HRLDUM and Dongfeng EQ4243V container vehicles.

[0020] The wheelbase C 12 and the wheelbase C between the center axle and the rear axle 23 , the distance l″ between the center pin of the trailer and the central axle, the weight of the empty vehicle T, and the weight of the front axle in the empty state P 1 ′, Central axle load P 2 ′, Rear axle weight P 3 ', the angle θ between the trailer frame and the horizontal axis, and the container length L' are stored in the computer, and the mathematical model of the center of gravity l of the container along its length l = A + ( P 3 - P 3 ′ ) × ( C ...

Embodiment 2

[0024] Basically the same as embodiment 1, the difference is the correction coefficient δ = - K 1 * ( P 1 - P 1 ′ ) G cos θ , K 1 Between 1000 and 1500, the mathematical model of the center of gravity l of the container along its length l = A + ( P 3 - P 3 ′ ) × ( C 23 ...

Embodiment 3

[0029] The difference from Example 1 is the correction factor δ = - - K 1 * ( P 1 - P 1 ′ ) G cos θ + K 2 ( P 2 - P 2 ′ ) * l ′ ′ G cos θ , Correct the cargo center of gra...

Abstract

The invention relates to a weighing method by box-dividing of a container vehicle dual-box carrying, belonging to the weighing field of a container truck which carries the container. The method comprises the following steps: (1) all vehicle types and data parameters of trailer are memorized; (2) a mathematic model of 1 equal to A plus (P3 minus P'3) multiplied by ((C33 plus 1') / Gcos Theta) plus delta of the center 1 of gravity of goods along the length direction of the container and a weight mathematic model of the front container and the rear container of G1 equal to G(3L' minus 2l) / 2L' and G2 equal to G(2l-L') / 2L' are established and written into recognition management software; wherein, A is a constant ranging from 400mm to 1000mm; Dheta is ranging from 0 DEG to 30 DEG; Delta is a correction coefficient; (3) data of the full vehicle weight W and weight of all axles under static heavy vehicle state are recorded, the total weight G of goods is equal to W minus T by calculation; (4) the center 1 of gravity of goods along the length direction of the container, the weight of the front container G1 and the weight of the rear container G2 are worked out. The weighing method can respectively measure weights of all axles, total weight and respective weight of two containers by one-step balancing.

Description

technical field [0001] The invention relates to a box-divided weighing method for container vehicles carrying double boxes, and belongs to the field of weighing containers carried by container trucks. Background technique [0002] As a measuring device, the truck scale mainly weighs the tare weight and gross weight of the transporting goods vehicles to further obtain the net weight of the carrying goods, and has been widely used in the weighing of port goods. For vehicles transporting containers, the net weight is the total weight of the loaded container, that is, the weight of the cargo plus the weight of the empty container. At present, truck scales are mainly used to weigh containers in major ports to obtain the total weight of containers. With the development of the transportation industry, one container truck loading one container can no longer meet the needs of logistics, and sometimes one truck loads two containers. Therefore, when a container vehicle carries a conta...
