Steel slab warehouse entering control method

Abstract

The invention discloses a steel slab warehouse entering control method and belongs to the information technical field. The method includes the following steps that: information of slabs to enter a warehouse and information of slabs and stack positions in the slab warehouse are determined; a mathematical model and process constraint conditions thereof of slab warehouse entering scheme evaluation indexes are established; an initial slab warehouse entering scheme is determined; the initial slab warehouse entering scheme is optimized through adopting a neighborhood task order exchange-based search iteration method; a final optimal slab warehouse entering scheme, adopted as an execution operation instruction of slab warehouse entering transfer equipment, is transmitted to a transfer equipment terminal controller, so that operation can be performed; and the transfer equipment arrives at a designated position under the control of a GPS positioning system, so that warehouse entering operation control of warehouse entering slabs can be completed. According to the steel slab warehouse entering control method of the invention, the stack positions where the warehouse entering slabs are stacked are reasonably arranged, and therefore, potential stack collapse of slab preparation materials can be decreased fundamentally, and the operation distance of the transfer equipment can be controlled, and the work efficiency of the transfer equipment in the slab warehouse can be improved, and logistics cost of the slab warehouse can be decreased, and the production efficiency of a production line can be improved.

Description

Technical field [0001] The invention belongs to the field of information technology, in particular to a storage control method for iron and steel slabs. Background technique [0002] Aiming at the problem of stacking steel slabs in the warehouse, that is, the decision of the stacking position of the slabs in the warehouse, the physical stacking process requirements (including Width group and length group) and the matching process requirements of slabs and stacks (including slab flow direction, contract, tapping mark, etc.), physical stacking process requirements ensure the safety of slab stacking, and the matching of slabs and stacks Process requirements ensure that additional stacking is reduced when slabs are extracted for rolling. At present, most of the slab stacking decisions are made manually. Due to the limitation of manpower, only the physical stacking process requirements are often considered, and the stacking position cannot be determined comprehensively under the...
