Embodiment 1

[0043] to combine figure 1 and figure 2 In this embodiment, in order to realize the full speed control and precise positioning of the unmanned crane, its control system mainly includes the crane operation information acquisition unit, the crane path prediction and planning unit, the crane operation interval setting unit, the speed control curve and the optimization unit, anti-sway control unit, crane running speed and positioning control unit.

[0044] When the warehouse management system issues a crane scheduling task, the crane operation information acquisition unit obtains the actual position of the crane and the corresponding avoidance point information. According to the actual position of the crane and the information of the corresponding avoidance point, the path prediction and planning unit of the crane will predict and plan the path in advance, and will issue an alarm for the avoidance point and the target point that are not within the allowed operating area during o...

Embodiment 2

[0058] Before the warehouse area management system issues the crane scheduling task, the crane operation information acquisition unit will obtain the actual operating position information of all cranes in the warehouse area and the corresponding operating status of the cranes in advance, and combine these information with the cranes that are about to perform tasks For the target point to be run, the path and the corresponding avoidance point are generated in advance. The path is directional, and it will directly give an alarm to those who are not within the allowed operating area during the journey.

[0059] The crane operation information acquisition unit acquires the following information:

[0060] 0N# crane actual coordinate information C0N(Xn, Yn) in the storage area

[0061] Crane running status information (1 is running, 0 is stopped)

[0062] If it is in the running state, there is direction information (1 positive direction, 0 negative direction) and the final target ...

Abstract

The invention discloses an anti-swing whole-course speed planning control and positioning system and method for an unmanned crown block, and belongs to the technical field of intelligent control of a metallurgical reservoir area. In the automatic operation process of the unmanned crown block, under the condition that a plurality of avoiding points exist in the path information issued by the warehouse management system, path prediction and planning are carried out in advance, under the condition of anti-swing control, the whole-course speed control and accurate positioning of the crown block are realized, and the process of turning back operation of the crown block mechanism does not exist in the path operation process, so that the operation efficiency of the unmanned crown block is improved. And automatic crown block control which does not stop in the whole process and maximizes the overall operation efficiency of the crown block is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent control of metallurgical storage areas, and more specifically, relates to a whole-process speed planning control and positioning system and method for unmanned crane belt anti-sway. Background technique [0002] In most metallurgical warehouse areas, crane operations are involved. Traditionally, the crane commander (referring to the lathe operator) on the ground directs the crane operator to complete the crane operation task through the walkie-talkie. Different cranes have different commanders to command operations. Due to factors such as the long track of the crane, the narrow field of vision of the ground commanders, and the poor communication between the commanders, when multiple cranes perform tasks at the same time, one Cranes sometimes wait for another crane, or even back up, which not only seriously affects normal production, but also poses a serious safety hazard. [0003] The intell...
