Active visual technology-based monitoring system used for crane remote operation and implementation method thereof

Abstract

The invention discloses an active visual technology-based monitoring system used for crane remote operation. The monitoring system comprises a main control computer and camera shooting equipment. The main control computer is provided with an image processing software, and is cooperatively connected to a server through a data I / O interface; the camera shooting equipment is used for taking images of a container loading and unloading scene, and is controlled by the main control computer to process obtained images of key procedures of each operation step, and to transfer the images of the key procedures to a display device for displaying, wherein the key procedures need attention; and then operators can control the crane to complete loading and unloading operations of containers remotely in an operation room according to the image displayed by the display device. Advantages of the monitoring system are that: remote monitoring and operating of each operation step can be realized by using the active visual technology, by taking images of the container loading and unloading scene with the camera shooting equipment, by processing obtained images of key procedures of each operation step, and by displaying the images with the display device. Investment cost of the monitoring system is low, maintenance is simple, and the monitoring system is capable of realizing all-weather operations.

Description

technical field [0001] The invention relates to video monitoring technology for remote operation of container gantry or bridge cranes used in container terminals or storage yards, in particular to a monitoring system for remote operation of cranes based on active vision technology and its implementation method. Background technique [0002] When working in container terminals or yards, the driver of the container crane usually sits in the driver's cab bending over and operating the equipment with his head down. Occupational diseases such as lumbar or cervical spine injuries. Changing to remote operation, the driver can sit in an operating room with a better working environment far away from the equipment, and operate the equipment facing the display image, which can greatly improve the driver's working environment and reduce the driver's physical exertion. Semi-automatic or fully automatic driving, a driver can watch several devices at the same time, which can also greatly ...

Problems solved by technology

At present, there are two commonly used remote operation video monitoring systems, one is based on laser scanning system, that is, through the laser scanner and camera installed on the crane, the outline scanning and shooting of the stacked containers are carried out, and the scanned The results are converted into three-dimensional graphics in real time and displayed on the monitor of the remote operator, thereby guiding the driver to load and unload the container. The disadvantage of this system is that it requires a large one-time investment, high maintenance costs, and the laser scanner is very demanding on the environment when it is used. High, fog, rain, and dust on the surface of the scanning lens will affect the scanning results

In this way, on the one hand, the video images that need to be transmitted to the remote driver’s console occupy a large bandwidth, and the cost of the required equipment is high. On the other hand, the driver still needs to find and select key parts in the panorama when operating. The workload is large and the efficiency is low.
