At present, some alcoholic beverage manufacturers are trying to use Internet of Things technology to present the entire product production process from raw materials to finished products and then to consumers through logistics. This article starts from the design of Ultra High Frequency (UHF) electronic tags in Radio Frequency Identification (RFID) technology to find collectible data that can replace ordinary barcodes and associate them with the system platform. Using terminal equipment, the data can be collected over long distances. Read accurate data to achieve product traceability and control. From production and warehousing to market sales and circulation, some products have achieved five-code correlation. Information such as production warehousing, sales outbound, quality inspection and spot inspection, and warehouse staff inventory counting are transmitted to the system by scanning the QR code on the pallet. , and then associate each product information with the shipping customer information from the system, so that each product has production information and outbound logistics information, which greatly facilitates consumers to check the authenticity of the product. However, entering information requires manual scanning and verification one by one. Each operation requires a lot of repeated physical labor, which increases the workload of the staff and makes inventory counting less efficient.
RFID technology has the characteristics of electronic tags that store a large amount of information, are quick and easy to read, and are not easy to copy. It enables the visualization of information such as product origin, production date, validity period, manufacturer, etc. With the development and evolution of this technology, it is gradually used in procurement and warehousing. , production, packaging, unloading, distribution, sales and other links are widely used. Therefore, embedding UHF electronic tags in products can not only quickly upload each product information to the system, improve the efficiency of product inventory and transfer, save a lot of repetitive manual labor, but also eliminate counterfeit products through the anti-counterfeiting traceability system.
To realize the full-process logistics traceability and control of wine, it is necessary to research and design a complete RFID system that can accurately read in an environment with multiple liquids, complex accumulation, and debris obstruction. In the entire wine production to sales transfer process, in addition to collecting and reading scenes one by one (bottle or box) on the production line, electronic tags also need to read scenes remotely in the transfer warehouse for inventory and traceability management.
To be able to accurately read tags in environments with lots of liquids, complex accumulations, and obstructions, the tags must meet the liquid resistance, chip sensitivity, and omnidirectional reading requirements of the tag antenna. At the same time, the reader combination (RFID Reader and Antenna) must be met. Must have good reading performance. The sensitivity of the UHF electronic tag chip (TAG CHIP) and the performance of the antenna (TAG Antenna) have the potential to meet the reading requirements of usage scenarios.
The UHF antenna determines the reading performance of the tag. In the face of multi-liquid and complex accumulation scenarios in wine storage sites, the linear design of the antenna needs to be designed accordingly to resist liquids. By designing the antenna of the electronic tag and binding it with a highly sensitive UHF chip, after selecting the labeling position, long-distance reading can be achieved in multi-liquid and complex accumulation scenarios in wine management, and can be implemented in traceability management. Reading through walls.
Choose a highly integrated, common handheld reader that uses an 8 dbi antenna.
According to the information network architecture theory of RFID technology, an RFID label is attached to each bottle of wine packaging. This label contains an RFID code to identify the bottle of wine, and then the detailed information of the product can be queried through this RFID code.
Through research and testing of RFID systems for product accumulation in complex environments, choosing a higher sensitivity UHF chip can improve the group reading rate of UHF electronic tags in multi-liquid and complex accumulation environments; the design of electronic tag antennas is narrow and long, with a large aluminum layer area and The wired radiation opening cavity will increase the backscattered signal and further improve the group reading rate in a complex stacking environment; the larger the exposed area of the reader antenna, the greater the intensity of the received and returned signals, making group reading easier. The higher the rate; at the same time, when building an RFID system, the antenna gain dbi of the reader is not as large as possible. The antenna gain should be selected considering common application scenarios.
and adjustments.
