Problems solved by technology

If the twist locks are not completely removed at this time, it will lead to a yard collapse accident due to the solid connection with the lower container during the re-transfer process
[0003] At present, ports at home and abroad mainly prevent such accidents through manual detection, but the working environment of the port is harsh and complex, labor intensity is high, and it is easy to be negligent due to personnel fatigue, so there is an urgent need for a container twistlock detection device Carry out detection and early warning

Embodiment 1

[0050] Step 1: Install 2-channel cameras (total 4-channel) on the columns beside the dragon legs at the front and rear ends of the gantry crane, and mark them as 1, 2, 3, 4, and No. 1, 2, 3, and 4 at a time from the front end to the parking space, and use them to obtain containers of different sizes Image information for frontend and backend. Preferably, the inner and outer corners of the same end (front end or rear end) of the same container always appear in the same camera at the same time without being blocked. Among them, the installation position of the camera is as follows: figure 2 shown.

[0051] Step 2: When it is used for the first time or needs to be re-calibrated, use a 4-way camera to collect a series of image data of abnormal working conditions in which the twistlocks have not been completely removed during container loading and unloading to form a sample image database. Preferably, the twistlocks that have not been removed should include various models as muc...

Embodiment 2

[0059] Step 1: Install 3 cameras (6 cameras in total) on the columns next to the dragon legs at the front and rear ends of the gantry crane, respectively, to obtain image information of the front and rear ends of containers of different sizes. Preferably, the inner and outer corners of the same end (front end or rear end) of the same size container always appear in the same camera at the same time without being blocked.

[0060] Step 2: Use the four-way camera installed in step 1 to collect image data of a series of abnormal working conditions in which the twistlocks are not completely removed during container loading and unloading. Preferably, the twistlocks that have not been removed should include various models as much as possible, and the working environment should cover all kinds of weather, such as rainy days and foggy days.

[0061] Extract the feature information of the spinlock in each frame sample image.

[0062] The above feature information is counted and a model...

Abstract

The invention relates to a detecting system and method for spin locks of containers. A visual field of a collecting system covers four corners of the container bottoms of the containers with a plurality of sizes, an IO module collects video data output by the collecting system, and analysis is carried out to generate image data; if a detecting module outputs an alarm signal, the IO module outputsthe alarm signal of the detecting module to a gantry crane control system; and the detecting module reads the image data analyzed by the IO module after receiving a crane signal, whether the spin locks exist in the container bottoms of the containers or not is judged, and if so, the alarm signal is output. According to the detecting system and method for the spin locks of the containers, machine visual technology is used, automatic detecting, recognizing and tracking of the spin locks not removed of the container bottoms of the containers are realized, and the working efficiency is improved. Adetecting result is connected to a hanger control circuit, a hanger is controlled to stop working under the abnormal working conditions, and accidents are prevented. A crane state and container typescan be automatically recognized, the change of a gantry control device is reduced, and the universality is good.

Description

technical field [0001] The invention relates to a container twistlock detection system and a detection method, in particular to a container twistlock detection system in the process of container loading and unloading by a gantry crane using machine vision technology. Background technique [0002] In port operations, for the sake of safety, during the transportation of containers, twist locks are installed under the four corners of the containers to securely connect them with transport vehicles or other containers. The twist locks below the corners of the box are all removed. If the twistlock is not completely removed at this time, it will cause a yard collapse accident due to the solid connection with the lower container in the retransfer process. [0003] At present, ports at home and abroad mainly prevent such accidents through manual detection, but the working environment of the port is harsh and complex, labor intensity is high, and it is easy to be negligent due to per...
