Embodiment Construction

[0041] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0042] Such as figure 1 In order to automate the layout of the container area of ​​the terminal yard, the sea-side crane and the land-side crane span the container area and run on the same track, which cannot be crossed. There are two types of tasks, container storage task and container retrieval task. The operation process is as follows: 1) when the container storage operation is performed, the crane lifts the container from the transfer position at both ends and transports it to the corresponding storage position; 2) when the container storage operation is performed During the container picking operation, the crane lifts the container from the container picking position and transports it to the ...

Abstract

The invention discloses a double crane real-time dispatching-control cascading system and method. The system comprises a dispatching layer and a control layer. The dispatching layer receives double crane dispatching task information and conducts recombination dispatching and real-time optimization, and the dispatching plan is obtained. The input end of the control layer is connected with a dispatching layer cascading structure, the output end is connected with a main motor of each crane, calculation is conducted according to the dispatching plan, the optimal control value is generated, and thecranes are regulated and controlled in real time according to the optimal control value. The system solves the problems that the dispatching plan real-time performance is poor, efficiency is low, andaccuracy and stability of the control system are poor; and dispatching plan and control scheme parameter sharing is achieved, mutual feedback and coordination are achieved, and it is guaranteed thatcontinuous system work stability and accuracy are kept when faults happen.

Description

technical field [0001] The invention relates to the field of dispatching cranes in an automated container terminal yard, in particular to a real-time dispatching-control cascading system and method for double cranes. Background technique [0002] The automated container terminal yard usually consists of several container areas, and each container area is equipped with one or more cranes for loading and unloading of containers. There are mainly three operating processes at the terminal: import boxes, export boxes and transfer boxes. At present, due to the high operational flexibility of the double crane configuration, most of the import and export containers are stored in a mixed storage mode in the container area to improve the operation efficiency of the storage yard. [0003] At present, the mixed storage of import and export containers in the automated container terminal yard is scattered in the bays and ranks corresponding to the container area. The two automated yard ...
