RFID technology in the solution of salt tracking and traceability management system

The National Food and Drug Safety “Eleventh Five-Year Plan” clearly requires the establishment of a food safety information system. Food management and production departments must establish supervision and quality traceability methods for the production and circulation of food, and have the ability to prevent safety problems caused by food. Although my country implements a franchise system for table salt, this should be a great advantage for building a traceable salt safety system. However, at the present stage, salt management and production departments hardly have a management system that can ensure salt safety, and traceability is even more impossible. .
The tracing and tracing of table salt is a complex project, including the production and sales of table salt. In the whole process, the sales link of table salt is the key, and fake salt and private salt enter the market from the sales link. Therefore, it is necessary to ensure that the entire salt sales link is in a monitorable state, so that consumers can understand the entire sales and circulation of salt products, and make the supervision channels open and transparent, so as to better enhance consumer confidence and ensure consumer safety.
RFID-based salt tracking and traceability system structure:
(1) CC: The National Control Center is responsible for collecting national salt circulation information from various provincial/municipal administrative centers, and conducting macro-control and planning. Supervise the safety of salt products in the entire country, and can release messages to various subsystems.
(2) SC: The administrative center stores and backs up the received data, and provides a query interface. When the user needs to inquire, visit the administrative center website through the browser, and enter the product ID to be queried and provide the corresponding authority information, and then the logistics information of different security levels can be obtained.
(3) DAP: Each manufacturer, distributor or secondary agent can be called a data collection node. Each data collection node will be equipped with several card readers (handheld/desktop). The card reader reads the data from the tag and performs simple processing, and sends the collected data to the data collection node in time for further sorting and consolidation, and then transmits it to its own administrative center for summary.
Taking into account the current situation of autonomous management of various administrative regions in our country, each administrative region can design a management system tailored to its own needs. However, in order to facilitate the unified management and query of national data, the same data structure should be used between various administrative regions to facilitate communication between administrative regions.
Characteristics of RFID salt tracking and traceability management application system
In addition to using card readers to obtain card data, there is also a management application system to process data and provide corresponding services. This system is designed in accordance with the salt management method and has the following characteristics:
(1) Have the ability to manage salt mines and salt-making enterprises. In order to achieve the purpose of supervising and supervising whether the enterprise has a legal status, and can judge whether the relevant enterprise is operating within its prescribed capacity.
(2) Manage related transportation companies/individuals. Ensure that supervisory and law enforcement personnel can conveniently inquire about the legitimacy of the identity of the transportation personnel of salt products, and whether the transportation scope complies with the regulations, etc. Ensure the safe and orderly circulation of salt products.
(3) Manage salt operators/sellers. Law enforcement personnel should be able to conveniently inspect and supervise the implementation of local salt industry management regulations and national salt industry regulations and rules by operators/sellers, and should be able to easily deal with parties, witnesses and salt involved in salt industry violations. Other units or individuals involved in illegal activities can conduct investigations and inquiries, and be able to obtain evidence in written or voice.
(4) Reserve an inspection and supervision interface for the salt industry quality inspection agency, so that the work of the quality inspection agency can be carried out conveniently and efficiently to ensure the safety of salt products.
