Problems solved by technology
However, the independent traceability islands formed by each platform cannot form an effective traceability supervision in the case of scarce regulatory resources
Secondly, the food traceability code has the risk of double spending and lacks credibility
Furthermore, the current traceability platform cannot prevent the secondary damage caused by the identified problem food in the first place

Embodiment Construction
[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.
[0055] Such as figure 1 and figure 2 As shown, a food traceability health code method according to an embodiment of the present invention is divided into a traceability part and a collaborative supervision part, the traceability part is the main part, and the collaborative supervision step is parallel to the traceability process step;
[0056] in,
[0057] The traceback steps include:
[0058] Obtain initial traceability product information and initialize product health code status, and then initialize current traceable digital assets; obtain di...

The invention discloses a food health code tracing method and system, the method comprises a tracing part and a cooperative supervision part, and the cooperative supervision step and the tracing process step are executed in parallel. The tracing step comprises: obtaining initialized tracing product information and an initialized product health code state, and then initializing current tracing digital assets; obtaining digital asset circulation; and obtaining the terminal control of the digital asset circulation, and cancelling the circulation of a single tracing code. The cooperative supervision step comprises: obtaining product cooperative quality feedback of a traced product; and automatically executing a smart contract according to the quality feedback condition, and controlling the health state feedback of the tracing product. The system comprises a production module, a circulation module, a consumption module, a supervisor module and a detector module. According to the invention, through multi-party maintenance of the health state pool, the pressure of scarcity of supervision resources is relieved, and secondary damage caused by affirmation of a defective product can be prevented at the first time when the defective product appears.
Description
technical field [0001] The invention relates to the application fields of food safety and traceability, in particular to a method and system for food traceability health codes. Background technique [0002] With the expansion of China's food production and consumption scale, the fast-growing food industry can effectively alleviate the domestic food shortage problem. However, the food safety incidents in recent years have exposed the long-standing shortcomings of the food safety supervision mechanism, and have also attracted the attention of all sectors of society to food safety issues. [0003] At present, in response to food safety issues, scholars and companies from all walks of life have proposed to establish a food traceability platform for supervision. The current platform models for food traceability are divided into: self-built platforms by enterprises, platforms established by governments, and third-party service platforms. However, the isolated islands of traceabi...
