Container weighing method and system

Abstract

The invention discloses a container weighing method and system, and the method comprises the steps of driving a Z-axis moving mechanism of a hoisting device to move to a set height according to the distance between the hoisting device and the top of a container after the total weight of a vehicle loaded with the container is weighed, and controlling an XY-axis moving mechanism of the hoisting device to obtain the position of a hoisting hole of the container; after the XY-axis moving mechanism and the Z-axis moving mechanism are driven to drive a lifting appliance to descend to the position of the lifting hole and lock the container, driving the lifting appliance to lift to finish the vertical lifting of the container; and weighing the net weight of the vehicle after the container is lifted, and obtaining the weight of the articles in the container according to the total weight of the vehicle, the net weight of the vehicle and the self-weight of the container. The weight of articles in the container is obtained according to the total vehicle weight, the net vehicle weight and the self-weight of the container, and the container does not need to be unloaded and then weighed, so that the authenticity of the weighing data is guaranteed; when the container is hoisted, the position of the hoisting hole of the container is automatically obtained, and the full-automatic unattended weighing is achieved.

Description

technical field [0001] The invention relates to the technical field of containers, in particular to a container weighing method and system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As a large-scale loading container for imported cotton, the container has been manually unpacked and weighed during the customs cotton inspection process; its loading and unloading efficiency directly affects the operating efficiency and throughput of the port; affects customers The work efficiency of customs declaration and exit; at the same time, the unattended weighing process can effectively eliminate the integrity risk of inspectors. The weighing of the container is the key point in the transportation system. For the weighing of the container, the existing method is adopted. One is to install a floor scale on the ground, use a crane to lift the cont...

AI Technical Summary

Problems solved by technology

[0004] (1) The efficiency of multiple lifting is too low, and the workload is increased;

[0005] (2) If there is a container overweight, the container overweight warning can only be known after the container is unloaded and weighed, that is, it is impossible to effectively and quickly know whether the container weight meets the requirements, and it also increases the number of container weighing;

[0006] (3) The existing method also has the problems of container weight fraud and untrue data, because the container needs to be unloaded and weighed first, and after the weighing is completed, it is hoisted to the transport vehicle, and the container will appear after unloading. The phenomenon that the item is removed and the weight of the actual item is falsified;

[0007] (4) The work efficiency is low, and the whole weighing process takes 4 hours to complete the total weight of a box
