Hot rolling slab yard two-crane-spanning automatic control method

Abstract

The invention discloses a hot rolling slab yard two-crane-spanning automatic control method. Under the premise of ensuring a safe distance of driving, a computer system calculates and allocates, according to a target position of a driving crane working task and a real-time position fed back by a driving crane, a lifting area of another driving crane, and then coordinates working executing processof the driving cranes according to priority, task generation time and waiting time of each driving crane, and then efficiency of cooperation working spanning the two driving cranes is improved. The driving crane working task is allocated through a dynamic red line method. When the same spanning driving crane conflicts in task execution, the optimal driving crane cooperation working scheme is calculated according to the task priority, issuing moments, avoidance time, etc., so defects of high labor intensity, misoperation and the like caused by manual intervention for driving crane working can be effectively overcome, and working efficiency of slab yard driving cranes are effectively improved. The method can be put into use in the steel industry involving storage management, and the method has great application and promotion values.

Description

technical field [0001] The invention relates to the technical field of driving control for a hot-rolled slab warehouse, in particular to an automatic control method for two vehicles at the same span in a hot-rolled slab warehouse. Background technique [0002] At present, the driving operation of the hot-rolled slab warehouse is generally selected by the operator and sent to the driving positioning system (CLTS) through the warehouse management system. management system. In the actual production process, there are various types of driving operations and different priorities, and there is often a phenomenon of cross-operation in the same span. Because the human factor of the team operation is dominant, the driving orders are often not allocated reasonably, and there are also scheduling problems during execution. Unreasonable problems lead to low driving execution efficiency and ultimately affect the feeding rhythm. Taking the slab warehouse of a steel factory in Shanghai as...

Problems solved by technology

[0003] At present, the cooperative operation between the vehicles is completely manual, which has the following disadvantages: 1) There are many manual interventions and the intensity is high. The frequent intervention of the operator not only increases the labor intensity of the operator itself, but also is not conducive to the fine management of the slab; 2) ) The driving operation efficiency is low, and the manual coordination of the driving operation cannot comprehensively consider the priority of the driving operation, task time and other factors, so the decision made is not optimal, which also reduces the operating efficiency of the driving
