Method for intelligently tracking tube numbers in circulating process of steel tube production line

Abstract

The invention discloses a method for intelligently tracking tube numbers in the circulating process of a steel tube production line. The method includes the following steps that areas are obtained through division, and a database is established; information is recorded; signals are recognized; tracking and positioning are performed, and actions of steel tubes correspond to corresponding data processing steps, so that circulating of the steel tubes on the production line with the corresponding tube numbers is tracked and positioned. The tube numbers of the steel tubes are collected into a system through information collecting points, then the steel tube numbers are bound to the steel tubes, and the action signals for entering and exiting from roller ways and the areas are displayed through an upper computer, so that the steel tubes are accurately and visually positioned according to the tube numbers, the number of recognition points is reduced, and efficiency is improved.

Description

technical field [0001] The invention relates to a pipe number tracking technology for a steel pipe production line, in particular to a method for intelligently tracking the pipe number when the steel pipe production line is circulating. Background technique [0002] In steel pipe companies that track by pipe number, each production process must enter the pipe number manually or through devices such as barcodes, which takes a lot of time and labor, and is also very cumbersome. There are obvious shortcomings in the manual identification of steel pipe numbers. The main reason is that it is difficult to avoid human errors. Operators must input them into the relevant operation interface after manual identification. Especially for high-frequency straight seam welding (HFW) production process, due to the fast production pace, manual identification becomes more difficult. There are also many problems with identification methods such as barcodes. For example, barcodes usually have a...

[0002] In steel pipe companies that track by pipe number, each production process must manually enter the pipe number or use barcodes and other devices, which takes a lot of time and labor, and is also very cumbersome

There are obvious shortcomings in the manual identification of steel pipe numbers. The main reason is that it is difficult to avoid human errors. Operators must input them into the relevant operation interface after manual identification.

Especially for the high-frequency straight seam welding (HFW) production process, due to the fast production pace, manual identification becomes more difficult

There are also many problems with identification methods such as barcodes. For example, barcodes usually have a height of 20-30mm. Barcodes of such a height are not eye-catching enough to be attached to steel pipes and are difficult to capture. For HFW and SAWH processes, flying saws are cut to form a steel pipe. The corresponding pipe number and related information are generated in real time, that is, the barcode should be formed in real time, but it is not easy to form and paste it on the steel pipe in real time synchronously with the production. It is especially difficult for the electric resistance welding (ERW) process with a faster production speed; the surface of the steel pipe may Unsmooth, unclean, emulsion or water exists, making it difficult or not firm to paste; if it is pasted on the outer surface of the steel pipe, it will be easily damaged during transportation, and it is difficult to protect the barcode on flaw detection equipment due to water on the surface of the steel pipe; If it is pasted on the inner surface of the steel pipe, it will be in contact with water during the hydrostatic test, which may cause damage to the barcode; laser scanning of the barcode requires more precise position alignment, and with the movement and rolling of the steel pipe during the production process, it is difficult to achieve automatic barcode position control. Scanning requirements; for the barcodes directly printed on the outer surface of the steel pipe, there are also problems such as scratches during the transportation and production of the steel pipe, and the automatic scanning cannot be performed because the position cannot be fixed.
