Description

Technical Field

[0001] The present invention relates to the field of electronic information technology, and in particular to a tracing system and method for realizing electronic supervision code intercommunication based on secondary nodes. Background Art

[0002] With the rapid development of information technology, electronic supervision codes, as an important means of product traceability, have been widely used in many fields. Electronic supervision code technology enables full-process traceability of products from production to consumption by giving them a unique identification code. The development of this technology not only improves the quality control level of products, but also enhances the information transparency of consumers and promotes the healthy development of the market.

[0003] At present, the electronic supervision code technology mainly relies on the first-level node, that is, the centralized server or database to store and manage product information. In the production process of the product, the electronic supervision code is directly printed on the product or its packaging box. After the product is coded, the validity of the assigned electronic supervision code needs to be identified. For unrecognizable electronic supervision codes, it is considered that the coding has failed. The system only has the coding function and cannot simultaneously realize the coding function and the identification function of the assigned electronic supervision code on the same production line. If the assigned electronic supervision code needs to be identified, it needs to be completed separately in the quality inspection link after the coding, which requires quality inspection resources, and the inspection results need to be re-compared and matched with the electronic supervision code of the data center to exclude illegal data. The business is complex and inefficient, thereby increasing the production cost of the product. In addition, although this centralized system ensures the centralized management and rapid query of data to a certain extent, it also has some limitations. For example, a centralized system may cause the entire traceability system to collapse due to a single point failure. At the same time, data security and privacy protection are also urgent issues to be addressed. In addition, the existing electronic supervision code system has poor data interoperability between different companies or organizations, which limits the sharing and use of traceability information, making data exchange and integration more difficult, and affecting the efficiency and practicality of the traceability system.

[0004] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, Chinese patent document CN202220255571.X discloses an online coding system for electronic supervision codes, which includes using a coding unit to code the product, and then using a quality inspection unit to identify the assigned electronic supervision code online without stopping the production line. Through the collaborative work between the coding unit and the quality inspection unit, the coding function and the identification function of the assigned electronic supervision code are realized on the same production line at the same time, thereby improving the coding efficiency of the packaging box skin, reducing the coding cost, and optimizing the coding process.

[0005] The above solution has solved to a certain extent the problem in the prior art that the coding function and the identification function cannot be realized simultaneously, the efficiency is low and the production cost is increased. However, the solution still has many shortcomings, such as: the data security and privacy protection are not good, and the data interoperability is poor, which limits the sharing and utilization of traceability information, resulting in greater difficulty in data exchange and integration, affecting the efficiency and practicality of the traceability system.
