Embodiment Construction

[0079] The specific content and steps of the steel coil inventory control method based on the crane positioning system of the present invention are:

[0080] 1. Install the crane laser positioning system-level transportation chain tracking and positioning system to coordinate the storage location in the steel coil warehouse and the rolling line transportation chain, and establish the storage location tracking for each steel coil.

[0081] 2. Use laser measurement technology to detect the running coordinates of the crane, combine the coordinate information with the crane operation command, display them together on the vehicle terminal, and transmit the results of the crane operator's operation to the coil warehouse management system in real time.

[0082] 3. Tracking of the transportation chain The running position of the steel coils in the transportation chain is tracked until the steel coils come off the assembly line and enter the steel coil warehouse; the steel coil warehous...

Abstract

Disclosed is a steel coil stock control method based on a crane positioning system. The method comprises the following steps: installing a conveying chain tracking and positioning system of a crane laser positioning system grade, conducting coordinate positioning on stock sites and rolling line conveying chains in a steel coil warehouse, establishing stock site tracking for each steel coil, detecting the operating coordinate of a crane through a laser measuring technology, combining coordinate information with crane work commands, and tracking the steel coil according to the operating position of the steel coil in one conveying chain till the steel coil is off line to be placed in the steel coil warehouse. The stacking principle in the steel coil warehouse is determined, a mathematic model and an algorithm are established, and optimized control over the stock of the steel coil warehouse is conducted through a crane positioning system, so the status of steel coil stock can be analyzed in an accurate and systemic manner, the functions of a steel coil warehouse management system are improved, crane positioning and steel coil warehouse management highly fit each other, automated operation of the steel coil warehouse is achieved, and the stock is increased. Moreover, the turnover rate of the steel coil warehouse and the work efficiency of workers are improved, the labor cost is reduced, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the field of application software and database development control, in particular to a method for optimizing the inventory of a hot-rolled steel coil warehouse based on a crane positioning system. Background technique [0002] A company's 1700mm hot rolling production line is a continuous casting-rolling production line organized according to customer orders. The rolling rhythm is fast. Theoretically, the inventory of its steel coil warehouse and finished product warehouse should not be too high. However, the current inventory is generally high, which not only takes up a lot of working capital, prolongs the production cycle, increases the production cost, but also sometimes interferes or hinders the normal production. Therefore, the inventory problem should be analyzed correctly and systematically, and the inventory should be effectively controlled. [0003] The steel coil warehouse management system is a subsystem of the manu...
