Method for designing ultra-high frequency radio frequency identification (RFID) label applied to identification of carton of cigarettes and label

Abstract

The invention relates to a method for designing an ultra-high frequency radio frequency identification (RFID) label applied to identification of a carton of cigarettes and the label, which belong to the technical field of radio frequency. A conventional packaging material of the carton of cigarettes, namely an aluminium foil film, serves as a radiator, a part of the aluminium foil film is removed to be designed into a slot antenna, a package of the carton of cigarettes is opened by utilizing segmentation lines of the aluminium foil film, and the physical destroy of the RFID label is finished simultaneously. The design method is particularly applied to cigarette manufacturing engineering in conventional tobacco industry by utilizing the conventional packaging material of the carton of cigarettes, so that cost is reduced greatly, and then the promotion of the RFID label in the tobacco industry is realized.

Description

technical field [0001] The invention relates to an RFID tag design method in the field of radio frequency technology, in particular to a UHF RFID tag design method suitable for cigarette case identification and the tag. Background technique [0002] In the tobacco industry, in order to establish a production process and an efficient distribution system, the sorting system [Sorting System] that plays a decisive role in logistics and distribution is the core. A variety of technologies are introduced to save costs, improve efficiency, and reduce labor-intensive. The traditional sorting system of the tobacco industry uses the RS485 Bus interface to collect data, which has the advantages of bar code (bar-code) and optical scanner [Optical Scanner], multi-node [Multi Node] support and long-distance high-speed induction communication. But it also has disadvantages such as the barcode system is susceptible to dust pollution, slow network speed, inconvenient real-time processing, an...

AI Technical Summary

Problems solved by technology

From an electrical point of view, since the aluminum foil used as a raw material for cigarette packaging is close to the attached RFID tag, an electrical equipotential surface [Equipotential Surface] is formed, which will lead to low reflection efficiency induced by RFID tags and parasitic elements [Parasitic Element], Resonant Frequency Shift [Resonant Frequency Shift], the overall readable distance and integrated recognition rate of the RFID system are significantly lower

Therefore, the fundamental limitation of adopting the method of attaching labels externally is that the electrical characteristics of the RFID system are low. At the same time, the tax rate in the retail price of tobacco in cigarette packs is as high as 70-80%. Tobacco manufacturers feel that the cost of introducing RFID tags is the largest. Burden, which fundamentally hinders the promotion of cigarette package identification [Item Level]
