1 Overview
In recent years, food safety crises have occurred frequently, seriously affecting people’s health, and arousing widespread concern around the world. Food goes through multiple links from raw material procurement to processing to transportation. There are many processes, and the supervision of a certain process may cause serious food safety and cause irreversible safety incidents.
In order to protect the health of consumers, reduce the occurrence of food safety incidents, and reduce the losses caused by this, a new generation of information technology is adopted to strengthen the effective management of information in each key link of food production, storage, packaging, and sales. This kind of information is monitored and managed to realize early warning and traceability, to prevent and build food safety problems. Once a problem occurs, it can also be traced back to the source quickly to prevent further expansion of the situation in time.
2. System design
The product anti-counterfeiting traceability system based on RFID technology designed by Zhilian Technology is launched after in-depth analysis and research on the industry. It adopts advanced RFID automatic identification technology and uses RFID electronic tags as anti-counterfeiting traceability information carriers. It integrates RFID technology and computer network technology. , Digital communication technology, database technology, software engineering technology in a large-scale information system. The system can be applied to the anti-counterfeiting traceability of high-end alcohol, tea, tobacco and other commodities, as well as the anti-counterfeiting traceability of high value-added valuables.
The anti-counterfeiting traceability system can not only effectively resist the phenomenon of counterfeiting, but also improve the efficiency of enterprise production and logistics, and improve the overall management level of the enterprise, thereby enhancing consumer confidence, improving product visibility, and establishing product brands. The use of RFID technology for anti-counterfeiting traceability, compared with traditional anti-counterfeiting technology, has the advantage that each tag has a globally unique ID number, which is directly written into the chip, which cannot be modified, is difficult to imitate, has no mechanical wear, and is anti-fouling.
3. System principle
Usually the electronic tag is placed on the object, and the reader sends out a certain frequency radio frequency signal through the antenna; when the electronic tag enters the radio wave receiving coverage of the reader, its micro-shaped antenna generates an induced current, and the electronic tag gains energy to be activated and read The reader sends the data and other information needed for identification (the electronic tag demodulates the command from the received radio frequency pulse and sends it to the control logic, and the control logic receives the command to complete the storage, sending data or other operations); the reader receives the information from the electronic tag Carrier signal, after demodulating and decoding the signal, it is sent to the computer host for processing; the computer system judges the legitimacy of the label according to logical operations, makes corresponding processing and control for different settings, and sends out instruction signals.
4. System composition
RFID-based product anti-counterfeiting traceability system is mainly composed of core database, anti-counterfeiting certification center, NFC mobile phone anti-counterfeiting query terminal, self-service anti-counterfeiting query machine terminal, and PC-side RFID anti-counterfeiting traceability system management software.
· The core database is mainly used to store the anti-counterfeiting traceability information of the product and the information related to the product. It is the core component and data source of the whole system.
· The anti-counterfeiting certification center consists of a core database and RFID anti-counterfeiting traceability services, and provides a unified service interface for the anti-counterfeiting query and traceability of the entire system.
· Anti-counterfeiting query machine terminal is used to facilitate consumers to inquire about product anti-counterfeiting at the point of sale and confirm the production and circulation information of the product.
· The NFC mobile phone anti-counterfeiting query terminal provides the functions of verifying the authenticity of the product and product traceability anytime and anywhere.
· RFID anti-counterfeiting traceability system management software, used for logistics tracking, sales management, product association, product information editing and other management.

6. Functions and advantages
1. Realize product anti-counterfeiting
Since the electronic tag has a globally unique code and cannot be copied, it is impossible for a counterfeiter to imitate a real electronic tag and can truly realize the anti-counterfeiting of the product.
2. Realize product traceability
In the process of commodity transportation, the logistics information is transmitted to the core database through the network in real time through the UHF handheld machine. When purchasing the commodity, the consumer can check the circulation information of the commodity at any time through the NFC mobile phone or the floor-mounted inquiry integrated machine. Realize the traceability of commodities.
3. Realize product logistics tracking
In the process of commodity transportation, manufacturers can view commodity logistics information in real time through the RFID anti-counterfeiting traceability system, and easily realize logistics tracking.
4. Realize product sales management
Because all the products sold are registered, manufacturers can get first-hand information at the first time. The timely and effective grasp of market dynamics allows manufacturers to adjust their market strategies in a timely manner. What is more important is to formulate timely and accurate implementation of sales strategies, which in fact greatly reduces the overall cost of sales.
7. System software configuration
1. Mobile phone anti-counterfeiting and traceability software / floor-standing query all-in-one machine anti-counterfeiting and traceability software
Used for consumer anti-counterfeiting traceability operations and dealers’ commodity registration operations
2. RFID anti-counterfeiting traceability system management software
RFID anti-counterfeiting traceability system management software is used for product registration, product information editing, sales management, anti-counterfeiting traceability, logistics management
