Visual material tracking method and system for on-line identification of flaw detection plates and representative plates

Abstract

The invention provides a visual material tracking method and system for on-line identification of flaw detection plates and representative plates. The method comprises the steps of pre-selecting steel billets of the representative plates and steel billets of the flaw detection plates for classification, then classifying the representative plates and the flaw detection plates through jet printing of plate numbers containing different tail end characters, and finally, realizing on-line type identification, on-line sampling and on-line flaw detection of the steel plates through a main display screen in an operation room and a display screen on a flaw detection station. Therefore, the steel plate type can be identified on line at the first time without looking over an MES system or a rolling plan list. Meanwhile, the phenomena of missing detection and missing sampling can be obviously reduced, the situation that flaw detection or sampling of a turning plate is conducted again is reduced, and the generation of non-plans is also reduced.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a visual material tracking method and system for online identification of flaw detection plates and representative plates. Background technique [0002] In the existing steel plate production line, each large steel plate has a unique 11-digit large plate number, and the function of the large plate number is to track the material of the steel plate and the area where it is located. In the prior art, according to product requirements, some steel plates require online flaw detection and sampling. [0003] However, the flaw detection or sampling process has the following defects: 1) The flaw detection and sampling position needs to check whether each board needs flaw detection or sampling through the planning sheet or MES, which is inefficient; 2) Due to the shortage of post personnel and some new workers The phenomenon of flaw detection board leakage and represent...

[0003] However, the flaw detection or sampling process has the following defects: 1) The flaw detection and sampling post needs to check whether each board needs flaw detection or sampling through the planning sheet or MES, which is inefficient; 2) Due to the shortage of post personnel and some new workers The phenomenon of flaw detection board leakage and representative board leakage sampling occurs from time to time, re-detection leads to complicated process, and wastes a lot of manpower and material resources; The contract delivery period is extended, which affects the contract delivery
