Description

technical field [0001] The invention relates to the field of steel coil transfer in the metallurgical industry, in particular to a method for precise positioning of steel coil sequences based on multi-carrier identification technology. Background technique [0002] Character recognition (OCR, namely Optical Character Recognition) technology refers to electronic equipment (such as scanners or digital cameras) to check the characters printed on the carrier, determine its shape by detecting dark and bright patterns, and then use the character recognition method to translate the shape into The process of computer writing. [0003] RFID radio frequency identification (RFID, Radio Frequency Identification) technology is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets.

Problems solved by technology

The current material transfer system is easily affected by optical imaging, external environment and some random factors, resulting in a character recognition accuracy of only about 70%.

Although the RFID radio frequency identification technology can improve the data identification accuracy through the reasonable application of the anti-collision algorithm, due to the influence of factors such as the position of the RFID label, the quality of the label, and the surrounding environment, the reading equipment still cannot accurately determine the order of the labels within the identification range.

The distortion of steel coil information is not conducive to the tracking and management of steel coil quality, and may even cause the automatic production system to be paralyzed
