chrispeng [ad_1]
Yunnan Pu’er tea has become the core brand of Yunnan tea industry with its excellent quality and profound cultural heritage. However, in recent years, there are also some crises that cannot be ignored in the Pu’er tea market. A small number of illegal enterprises and individuals often impair the reputation of Pu’er tea by pretending to be inferior or adulterated; counterfeit trademarks, trademark infringements, unlicensed business operations, fake production company names, and malicious speculation disrupt the tea market from time to time.
In product packaging, in response to the problems of Pu’er tea, Kunchuan Digital Technology Co., Ltd. proposed to use RFID technology as a platform to develop a “pu’er tea anti-counterfeiting authentication system” to protect the healthy development of the Pu’er tea industry and achieve targeted attacks Counterfeit products protect the interests of manufacturers and consumers.
Overall system deployment and application process
The anti-counterfeiting and traceability system of Pu’er tea consists of a front-end system, a back-end service system, and a communication network.
Front-end system
The front-end system is the antenna that constitutes the entire anti-counterfeiting traceability system. Using RFID tags as the information carrier and retrieval basis, it completes the information writing, identification, determination, and restoration of the entire logistics link of the product from the manufacturer, logistics, distributor to the final consumer And show. So as to achieve the consistency of logistics and information flow, ensure the uniqueness of a single product, and achieve identifiable and traceable. Relying on the multiple associations of electronic tags, paper tags, RFID reading and writing equipment, encryption/decryption algorithms and background database systems, the non-reproducibility of anti-counterfeiting information is guaranteed and the purpose of anti-counterfeiting traceability is achieved. The front-end system includes:
Product information registration subsystem: The product information registration subsystem is deployed in manufacturing companies and consists of barcode recognition equipment, RFID reading and writing equipment, and corresponding computer software and hardware. In the pressing link of the product, the electronic tags registered in the retrospective anti-counterfeiting system are pressed into the tea cake, and the product’s anti-counterfeiting code is encrypted and then written into the electronic label. At the same time, the tags are recorded in the local data cache, and the local data cache and the background database system establish a synchronization mechanism.
The product registration subsystem is the source of anti-counterfeiting tracking. In the production process, an information association between electronic tags, anti-counterfeiting tags and database systems is established to prevent the entry of illegal data.
Anti-counterfeiting information query subsystem: The anti-counterfeiting query subsystem is used in the tea sales link, and is divided into two types: fixed query machine and hand-held. The fixed query machine is used in large shopping malls, supermarkets or businesses that can access the Internet through computers. Just place the tea cakes with RFID tags on the inquiry table, and the system automatically recognizes the tag number and anti-counterfeiting code, and retrieves information such as manufacturer, product, production date, and production process.
The handheld RFID query machine is generally used in the merchant’s purchase inspection link, and is connected to the anti-counterfeiting database through GPRS for retrieval. At the same time, the back-end database system automatically records the information such as the inquired label, location, and inquiring machine number, which is used for the tracking of the entire logistics link.
Anti-counterfeiting website and SMS platform: Consumers scratch off the coating on the label, and verify the authenticity of the anti-counterfeit code through SMS or website. In addition to reflecting the authenticity of tea and product-related information, it also reflects the set according to the wishes of consumers Content such as “Marriage Celebration”, “Meeting Commemoration” and so on.
Back-end service system
The back-end management system of the anti-counterfeiting traceability platform includes manufacturer and dealer registration management, electronic label issuance and registration management, Pu’er tea product information management, electronic label query management, etc.
Manufacturer and distributor registration management: To ensure the authenticity of anti-counterfeiting information and the quality of products that have passed anti-counterfeiting certification, manufacturers and products entering the anti-counterfeiting system should first be certified by the Pu’er Tea Authoritative Certification Center. The electronic label is registered by the anti-counterfeiting traceability platform and the electronic label ID number is issued. Only the registered labels enter the production and circulation links to prevent the inflow of illegal channels.
Information related system issuance and registration management: In order to ensure the effectiveness of anti-counterfeiting, in addition to the unique identification of products with anti-counterfeiting labels, there are also corresponding “encryption/decryption” algorithms encapsulated in the corresponding read-write control software. Each set of distributed software uniquely corresponds to the reader to ensure the relevance of the RFID tag and the identification system. Therefore, the software system used for Pu’er tea anti-counterfeiting needs to be registered before production and then distributed to manufacturers and merchants for use. The system ensures the legitimacy of the reader.
Electronic label query management system: Pu’er tea companies enter the product information corresponding to the label into this system for storage. The content mainly includes the basic information of the product, such as: origin, manufacturer, brand, production date, variety, grade, etc., used to meet general requirements The needs of users to query anti-counterfeiting information.
Pu’er tea product information system: This system is mainly designed to meet the demand for more information on Pu’er tea, or used for higher-grade Pu’er tea information. In addition to basic information on anti-counterfeiting, the content mainly includes tea raw materials (from which type of tea tree), growth environment (climate, temperature, humidity of the year), picking time, production process, cultural connotation, subjective and objective provided by professional authorities or persons Evaluation etc.
Communication network
The main purpose is to use the existing network infrastructure to develop a transmission system for RFID information using mobile phone short messages, the Internet, GPRS, CDMA and other information transmission methods.
Equipment selection criteria
Considering the characteristics and needs of Pu’er tea products, combined with the characteristics of RFID technology, the project adopts 13.56MHz frequency band and IS015693 standard RFID technology and products. The product form includes software, hardware, and software and hardware systems or devices. The software is an anti-counterfeiting background management system, SMS platform and website, and the hardware is an RFID anti-counterfeiting product registration system, special encapsulated RFID tags, and various forms of RFID anti-counterfeiting inquiry machines. .
1. RFID tags: Adopt 13.56MHz, ISO15693 standard, UID 64Bits, theoretically the number of tags that can be used is 248 =281474976710656, and the storage capacity is 256bit RFID tags.
2. RFID product registration and query system: there are handheld and desktop query systems, using 13.56MHZ, Iso15693-compliant readers, tags and other products, which have recoil ability, can penetrate non-metallic materials, and read distance From 5CM to 40CM, it is suitable for Pu’er tea anti-counterfeiting and traceability requirements.
Handheld query machine: read one tag at a time, the reading distance is 50MM; small desktop query system: read one tag at a time, the reading distance is 50MM, USB or RS232 interface;
Integrated inquiry machine: Read less than 10 tags at a time, with a reading distance of 200MM, USB or RS232 interface. In the process of designing the technical scheme of this project, according to the characteristics and project requirements of Pu’er tea, many tests and comparisons were made on various technical standards of RFID, and finally the technology and products of HF (13.56MHz) and IS015693 standards were selected. The reasons are as follows:.
First of all, the use of RFID technology for anti-counterfeiting traceability of Pu’er tea products requires the RFID tag to be embedded in the tea cake, and the tag is not easy to be too large, which is difficult to achieve with UHF technology. Secondly, because the project needs to manage Pu’er tea logistics, the RFID technology used needs to have anti-conflict capabilities, and finally the HF ISO15693 standard technology and products are selected. During the development of the project, the development and design of anti-counterfeiting query equipment encountered many unexpected problems. For example, for hand-held inquiry, it is necessary to take into account the requirements of the interface of the mobile phone, the interface of the reader module and the reading distance; the demand for the integrated inquiry machine is to be able to read 7 cakes of Pu’er tea stacked together, etc. After continuous exploration, a series of software and hardware products supporting the system have been developed to basically meet the demand for anti-counterfeiting and traceability of Pu’er tea and achieve the project’s expected goal.
Implementation Effect
The use of RFID technology for anti-counterfeiting of dry Pu’er tea, combined with the construction of a Pu’er tea traceability system, meets the needs of enterprises, consumers, and governments in terms of market, technology, and economy. For production enterprises, it can enhance the value of the corporate brand, grasp market information and trends in a timely manner, manage inventory more effectively, reduce the amount of loss of goods, and improve the efficiency of the logistics supply chain. So as to greatly save costs and improve the overall competitiveness and service level of the enterprise. For dealers, the system can provide a convenient and authoritative way to provide consumers with authentic information and increase sales; it can also customize personalized information for consumers to meet various needs of customers.
