Visual identification system of container lifting appliance and container lifting method of container

Abstract

The invention discloses a visual identification system of a container lifting appliance. The visual identification system comprises a control device, wherein the control device is connected with videoinput devices and a display device, the video input devices are arranged on the lifting appliance, and the display device is used for displaying images shot by the video input devices; the four videoinput devices are arranged at the four corners of the lifting appliance respectively, and are used for shooting the four vertex angles of the container below and the positions of locking holes corresponding to all the vertex angles; then the images shot by the four video input devices are spliced into one image; and the control device is provided with a data processing unit and a butt joint unit,wherein the data processing unit identifies the contour features of the container and the features of the locking holes in the image and calculates the angle offset and the position offset between the container and the lifting appliance, the butt joint unit transmits the angle offset and the position offset calculated by the data processing unit to a plc, the plc controls the lifting appliance tobe adjusted and to lock the container, the lifting appliance is automatically aligned with the container for locking, so that the dependence on labor is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of port container loading and unloading, in particular to a visual recognition system of a container spreader and a container hanging method. Background technique [0002] In the current automated container loading and unloading operation process, most of the process is realized by PLC control unit control and sensor positioning technology. However, when the container is suspended, the spreader is aligned with the container, and the spreader lock is accurately inserted into the container. The keyhole is still completed by manual remote control, which leads to a strong dependence on labor in the process of container lifting and low efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a visual recognition system for a container spreader and a container hanging method that can improve loading and unloading efficiency and reduce la...
