[0007] 3) Due to the particularity of the downstream process, the arrival time of the transported raw materials has relatively strict restrictions. If it arrives at the storage tank too early, there may be nowhere to store it. If it arrives too late, it will affect the normal production of the downstream process. cause significant economic losses;

Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] One embodiment of the present invention takes the raw material factory of a large iron and steel company as an example. It is necessary to transport 6 different batches of raw materials from the stockyard to each production workshop. There are 55 available conveyor belts, 9 starting points for transporting materials, and 5 shipping destination, such as figure 1 As shown, the time interval T 0 = 5min.

[0025] In one embodiment of the present invention, the flow chart of the control method for the logistics transmission equipment in the iron and steel raw material field is given as follows: figure 2 shown. The process starts at step 201 . In step 202, the process data and control data in the conveyor belt transmission process are downloaded from the enterprise database, and the raw material information to be input is shown in Table 1:

Abstract

A control method and a control device for steel raw material yard logistics transmission equipment belong to the technical field of steel raw material production logistics. The control method includes the steps: describing a technical process and determining constraint conditions of the technical process by the aid of process data and control data during transmission of a conveyor belt; calculating raw materials conveyed by the conveyor belt at different time in order to minimize tardiness cost; and issuing results to a secondary process control system to control the logistics transmission equipment. The method is used for scientifically and quantitatively describing process features of the steel raw material transmission equipment during control, and controlling the transmission equipment by means of intelligent optimization algorithm based on description, so that a raw material transmission production system is in optimal operating state, the problems of interruption of raw material supply and the like caused by unreasonable distribution are avoided to a large extent, stable operation of the equipment is ensured, production is balanced, the utilization rate of the equipment is increased, production cycle is shortened, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel raw material production logistics, and in particular relates to a control method and device for iron and steel raw material field logistics transmission equipment. Background technique [0002] Conveyor belt (belt conveyor) is an important transmission equipment in the production process of steel industry, and its function is to allow materials to be transported to the designated destination continuously and uninterrupted. The logistics transmission equipment in the iron and steel raw material yard mainly includes the conveyor belt and its supporting transfer station. The transportation process mainly includes two stages: one is that the conveyor belt transports the raw materials from the dock to the stockyard for storage and processing; the other is that the raw materials are transported from the stockyard to the Blast furnace, sintering and other production workshops. Conveyor belts unde...
