Abstract

The invention relates to an on-line examination system and a method for a steel pipe. The system comprises a pipe mouth image collecting device, a pipe wall image collecting device, an upper computer module and a power source. The pipe mouth image collecting device and the pipe wall image collecting device are respectively connected with the upper computer module to collect the steel pipe mouth image and pipe wall image and then the steel pipe mouth image and the pipe wall image are sent to the upper computer module. The upper computer module is used for analyzing the collected image, rejecting disqualified steel pipe and counting parameter acceptability of the steel pipe mouth and the pipe wall. The power source is respectively connected with the pipe mouth image collecting device, the pipe wall image collecting device and the upper computer module and is used for supply electric power to the pipe mouth image collecting device, the pipe wall image collecting device and the upper computer module. The on-line examination system and the method for the steel pipe have the advantages that artificial interference is not needed, accuracy is high, precision and production efficiency are high, labor intensity is reduced, instantaneity is high, practical applicability is high and cost is low.

Description

technical field [0001] The invention relates to the field of steel pipe detection, in particular to an online detection system and method for steel pipes. Background technique [0002] Steel pipes are a major product produced by rolling mills of iron and steel enterprises, and are widely used as steel bars for construction, machinery manufacturing, and metal raw materials. In the production process of steel pipes, the quality inspection of steel pipes is the most important link. Effective quality inspection of steel ingots can ensure its production efficiency and product quality, and it is also a powerful guarantee for enterprises to obtain economic benefits. [0003] The traditional steel pipe inspection method adopts manual inspection, and the defective and unqualified steel pipes are eliminated through workers' observation on the assembly line. However, this detection method relies entirely on the experience of workers to judge the degree of defect of the steel pipe and...
