Description

Logistics conveying belt based on RFID technology Technical Field The invention relates to the field of logistics conveying, in particular to a logistics conveying belt based on an RFID technology. Background Along with the rapid development of the modern logistics industry, an automatic storage and sorting system becomes a key link for improving logistics efficiency, and the radio frequency identification technology is widely applied to a logistics conveying system due to the advantages of non-contact identification, batch reading, large data capacity and the like, so that real-time tracking and management of cargo circulation information are realized, an electronic tag is attached to the surface of the cargo, and when the cargo moves along with a conveying belt and passes through an RFID reader, an antenna in the RFID sends a radio frequency signal to the electronic tag and receives a response signal returned by the tag, so that automatic identification and collection of cargo identity information are completed. However, in the practical application process, the identification accuracy of the RFID reader to the electronic tags is limited by various factors, wherein the problem of signal interference between the tags is particularly remarkable, when the distance between two adjacent goods on the conveyor belt is too small, the two attached electronic tags are too close to each other in physical position, so that when the antenna of the RFID reader sends signals, the two tags are simultaneously in the identification range of the reader and respond simultaneously, at the moment, the radio frequency signals returned by the two tags are overlapped and aliased in space to generate a signal collision phenomenon, so that the RFID reader cannot accurately analyze the complete information of the single tag, and further the problem of identification errors such as misreading, misreading or failure in reading occurs, and the problem of signal interference is more serious in the scenes of dense goods arrangement, faster running speed of the conveyor belt or larger identification range of the reader. In particular, for the goods with easy moving or rolling appearance, the signal interference problem is further aggravated, such as the rod-shaped paper tube goods, when the goods are transported on the conveyor belt, because the cylindrical structure of the goods has instability, rolling, displacement or mutual approaching easily occurs, when two adjacent paper tube goods are mutually stuck due to rolling, the distance between the two attached electronic labels is rapidly reduced, and even the condition that the labels are in physical contact or overlap possibly occurs. At this time, the radio frequency signal coupling effect of the two tags is obviously enhanced, the signal interference degree is far beyond the general situation, the RFID reader can hardly distinguish independent signals of the two tags, serious identification errors are caused, and the accuracy and the efficiency of logistics sorting are seriously affected.
