Steel tracking and identification system

Abstract

The present invention provides a steel product tracking recognition system. The steel product tracking recognition system comprises: a plurality of carrying devices, a plurality of wireless Radio Frequency Identification (RFID) readers and a controller. The carrying devices are respectively arranged to a plurality of recognition areas, each carrying device comprises at least one carrying RFID tag disposed at one side of the carrying device, the carrying devices are used to carry steel products, and each steel product has a steel product RFID tag. The RFID readers are respectively arranged to two sides of the recognition areas, and are used to read the carrying RFID tags of the carrying devices and the steel product RFID tags to obtain reading matching signals of the recognition areas. The controller is connected to the RFID readers, gives a weighting value to each recognition area according to the reading matching signals of the recognition areas, and accumulates the weighting values of the recognition areas to determine positions of the steel products in the recognition areas. Manual operation cost expenditure can be largely reduced, and automatic operation can be achieved.

Description

technical field [0001] The invention relates to a tracking and identification system for steel products. Background technique [0002] The Radio Frequency Identification (RFID) system has the characteristics of long reading distance, fast speed and easy automation. It has been widely used in various industries in recent years. However, in practical applications, its long reading distance reduces the reliability of the RFID system and the accuracy of interpretation; and because of the radio wave radiation characteristics, it is difficult to accurately control the angle of its reading range, so the RFID system In application, most of them can only provide whether the RFID tag is read or not, but cannot determine the orientation or exact position of the read RFID tag. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tracking and identification system for steel products, which solves the problem that most of the RF...
