An agricultural product quality supervision traceability system based on a block chain

Abstract

The invention discloses an agricultural product quality supervision traceability system based on a block chain, and relates to the field of food safety management. The system includes an identification identifier, front-end information acquisition device, video processor,a video storage device and a traceability center system. The identification identifier is used for carrying out unique identifier coding on agricultural products and associating corresponding farm information; collecting breeding information in the production process through a front-end information collection device,the videoprocessor carries out identification; analysis and processing, obtaining information with a video image seal after the information is compared to be consistent; the video is transmitted to a cloud-endvideo storage device based on block chain storage; inspection and quarantine information in the whole production and sale process is written through the identification mark. When the tracing system enters the circulation field of wholesale, the corresponding identification mark is connected with the merchant information, so that the key information of the agricultural products entering the tracing system from the farm to the consumer can be conveniently and quickly recorded and inquired on the basis of real, detailed and complete conditions.

Description

technical field [0001] The invention relates to the field of food safety management, in particular to a blockchain-based agricultural product quality supervision and traceability system. Background technique [0002] Due to frequent occurrence of food safety accidents in our country, major epidemics such as bird flu and African swine fever have always plagued the development of the breeding industry. The country has also always emphasized the establishment of a traceability system for agricultural product quality and safety supervision under the background of big data. Over the years, the government has invested a lot of money to establish this supervision system. But so far there is no system that can effectively solve the problem of traceability of agricultural products and the tracking and tracing of major epidemics of agricultural products. The main reasons for the analysis are as follows: [0003] 1. The production cycle of agricultural products is long, involving many...

AI Technical Summary

Problems solved by technology

[0004] 2. The production units of agricultural products are uneven. There are large enterprises, cooperatives, large farmers, and individual farmers. There are a large number of scattered supervision objects. The supervision department is unable to record the detailed information of safety production in a complete, timely and accurate manner. Even the most The binding of the basic basic information of agricultural products cannot be completely authentic

For farmers with low education levels, they cannot complete information collection by themselves and increase their workload. They are unwilling to complete information collection, and still cannot obtain real agricultural product information.

[0006] 4. The existing information collection method is to fill in the form and record on the PC in the network environment, and the information cannot be timely and the authenticity of the information cannot be guaranteed. Without supervision, there is no credibility

[0007] 5. Due to the unique commodity attributes of agricultural products, the time from harvesting and processing to sales is very short and the quantity is very large. It is impossible to guarantee the authenticity, comprehensiveness and integrity of such a large amount of inspection and quarantine information in a very short period of time in the sales process.
