Embodiment Construction

[0019] refer to figure 1 , figure 2 According to the present invention, the control method for multi-path warehousing of hot-rolled rolling line steel coils includes the following steps:

[0020] (1) Tracking of the location of the steel coils in the warehouse. The process computer rolling line coil off-line performance, tracking position and storage request information from the process control system (L2) are collected on the production management computer (MES) through text communication;

[0021] (2) The decision-making control of the transportation route, the production management computer (MES) establishes the optimal transportation route for steel coil handling, and sends the start-stop information of the transportation chain through the process computer of the process control system (L2);

[0022] (3) The decision-making control of the storage location, the production management computer (MES) establishes the destination storage location of the steel coil, the product...

Abstract

The invention relates to a control method for putting hot-rolled rolling-line steel coils in storage in multiple paths and mainly solves the technical problems that in the prior art, the error rate is high and the carrying efficiency is low when the hot-rolled rolling-line steel coils are carried to a storage location of a steel coil storeroom. The technical scheme provided by the invention is that the method comprises the following steps of: 1) tracking of the positions of the steel coils which are put in storage: collecting put-in-storage request information of rolling-line steel coils of a process computer from a process control system on a manufacturing executing system by way of telegraph text communication; 2) decision control of a transport path: determining the optimum transport path of steel coil carrying by the manufacturing executing system and issuing transport chain start-stop information by virtue of the process computer of the process control system; and 3) decision control of storage location: determining the target storage location of the steel coils by the manufacturing executing system, generating a crane command and issuing the crane command to a crane in the region, wherein the crane executes the command to hoist the steel coils to the target storage location. The control method provided by the invention enables the hot-rolled rolling-line steel coils to be efficiently put in storage by using the existing manufacturing executing system and the process control system of an enterprise, and the cost is low.

Description

technical field [0001] The invention relates to a method for controlling hot-rolled steel coil storage, in particular to a multi-path control method for hot-rolled steel coil storage, which belongs to the technical field of metallurgy automation. Background technique [0002] The existing hot rolling line production is characterized by strong continuity, fast speed, and high degree of control automation. Generally, there are three or more computer systems, including the basic automation control system (L1), which is responsible for the direct control of equipment, and the process control system (L2 ), responsible for the control process parameter setting, production management computer (MES) system, responsible for production planning and logistics control. [0003] The steel coils produced by the hot-rolling rolling line generally go through processes such as coiling, bundling, weighing, and printing, and then enter the steel coil warehouse for stacking. Because differen...
