Method for on-line automatic information tracking of steel tubes

Abstract

The invention discloses a method for on-line automatic information tracking of steel tubes. Original information of a steel tube is sent to a steel tube information identification system through a port, the system converts the original digital-value information to bar code and digital-value information, and the bar code and digital-value information is tagged on the surface of the steel tube. An information identification system collects images of the steel tube surface in each work position of a production line, and the images are converted to recordable digital-value original information. The digital-value information is combined with the production information generated in each work position of the production line through an industrial network information port system, and finally a complement of steel tube information is achieved. The method uses a coding system of binary system or Gray code, and is advantaged by simple coding system, redundant function, high identification rate, and automatic identification function. The method is not only suitable to be applied in steel tube production lines, but also in steel plate production lines or other production lines with relatively poor work condition.

Description

technical field [0001] The invention relates to an automatic information tracking method, in particular to an automatic online information tracking method for steel pipes. Background technique [0002] Many steel pipe production lines organize production according to batches, etc., and it is impossible to accurately locate the information of each steel pipe. Often, information is lost or mixed batch production is caused due to scheduling or steel pipe offline and other factors. There are also some markings on the steel pipes by hand printing labels, etc., and tracking by manually scanning barcodes at subsequent stations. However, due to the long industrial process of steel pipe production, the working conditions are responsible, and there are various harsh conditions such as water and oil during the period. , It will often cause the logo to be lost, etc., and it takes a lot of manpower to organize this method, and the operation is not ideal.
