Crown block collision detection and intelligent collision avoidance method

Abstract

The invention discloses a crown block collision detection and intelligent collision avoidance method. The method specifically comprises the following steps of 1, whether two crown blocks are on the same rail or not is judged; 2, upon detecting the presence of crown blocks on the same rail, the state information and the task information of the crown blocks on the same rail are judged; 3, by means of a collision detection mechanism, whether the collision exists between two crown blocks or not is judged; 4, a crown block A enters an overlapped region firstly and has a high priority, while a crown block B is in the execution waiting state; 5, the crown block B stops outside the safety distance before entering the overlapped region and is switched into the waiting interruption state; 6, after the crown block A executes the hoisting and releasing operation at a target location, the crown block A begins to return; 7, the crown block B executes a task until the completion of the task. According to the invention, the enterprise production efficiency is improved, and the operation potential hazard of crown blocks is lowered. The method can be widely applied to crown block control systems in combination with crown block intelligent control and unmanned crown block autonomous operation in various warehouses and steel-making places.

Description

technical field [0001] The invention belongs to the technical field of crane control, and in particular relates to a crane collision detection and intelligent avoidance method. Background technique [0002] Most of the cross-sections of the steelmaking site and the various areas of the warehouse have multiple cranes running on the same track, and the cranes on the same track cannot cross each other. Two adjacent cranes or even multiple cranes have functions, Overlapping working areas. The operations of the cranes on site are all carried out by the crane commanders (referring to the lathe workers) on the ground who command the operators of the cranes to complete the operation tasks of the cranes 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 ...

Problems solved by technology

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 are waiting for another crane or even reversing from time to time, which not only seriously affects the normal operation and production, but also poses a great safety hazard
