[0011] Furthermore, the system management unit includes four submodules: blockchain settings, user management, personal settings, and message notifications;

[0012] Blockchain setting module: responsible for configuring blockchain network nodes according to the requirements of the construction unit, maintaining and optimizing the performance of the blockchain network, and preventing blockchain network failures;

[0013] User management module: used by construction units to sort out the participants in the brand supply chain, verify identities, allocate nodes, grant corresponding permissions to participating units, and submit the qualifications of participating units, standardized planting agreements, and brand co-construction agreement information to the main chain;

[0019] Furthermore, when the contract self-adjustment module automatically adjusts the on-chain supervision time of the quality inspectors of each node, it obtains the task completion time of each node and the on-chain time of the quality inspectors of each node within a period of time, and analyzes the obtained time information, so as to obtain the on-chain supervision time Tc of the quality inspectors of each node:

[0020]

[0021] Among them, dT i is the completion time of each task i in each node within a period of time, dT max , dT min are the maximum and minimum time for completing tasks in each node within a period of time, Z is the total number of tasks completed by each node within a period of time, oT j is the time j that the quality inspectors of each node go on-chain for supervision each time within a period of time, and S is the total number of times the quality inspectors of each node go on-chain for supervision within a period of time.

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Figure 1 This is a schematic diagram of the system principle. DETAILED DESCRIPTION

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0042] According to one aspect of the present invention, Figure 1 As shown, a blockchain-based agricultural product supply chain quality supervision system is provided, which includes five functional units: system management, contract management, quality management, supervision management, and quality traceability. First, the construction unit manages the blockchain system through the system management unit: the construction unit configures the blockchain network nodes as required through the blockchain setting submodule, and maintains and optimizes the performance of the blockchain network to prevent blockchain network failures. In addition, the construction unit sorts out the brand supply chain participants, verifies identities, allocates nodes, gives participating units corresponding permissions through the user management submodule, and submits information such as participating unit qualifications, standardized planting agreements, and brand co-construction agreements to the main chain. At the same time, personal information can be managed and improved through the personal settings submodule. Then, the message notification submodule is used to complete the information transmission of quality inspection of each node and the push of the younger brother of the supervision part, so as to complete the relevant communication between the nodes.

[0043] Then, the smart contract service is provided through the contract management unit, and the system functions are maintained and improved by adding smart contracts to ensure the scalability of the blockchain: first, the needs of each node and the contracts of each link are analyzed in detail through the contract deployment submodule, and the needs and contracts are coded and deployed on the blockchain, including the self-inspection contract of each node and the information entry contract of each node. Then, during the normal operation of each node in the blockchain, the contract self-adjustment submodule will obtain the task completion time of each node and the on-chain time of each node quality inspector within a period of time, and analyze the obtained time information, so as to obtain the on-chain supervision time Tc of each node quality inspector, and adjust the on-chain supervision time of the node quality inspector to each node self-inspection contract:

[0044]

[0045] Among them, dT i is the completion time of each task i in each node within a period of time, dT max , dT min are the maximum and minimum time for completing tasks in each node within a period of time, Z is the total number of tasks completed by each node within a period of time, oT j is the time j that the quality inspectors of each node go on-chain for supervision each time within a period of time, and S is the total number of times the quality inspectors of each node go on-chain for supervision within a period of time.

[0046] In normal work, each node in the blockchain analyzes the key factors affecting the quality of branded agricultural products in each link of the supply chain based on the HACCP principle through the quality information entry submodule in the quality management unit, determines the information collected and entered in each link, and each participating unit uploads the quality work information responsible for the unit to the system. For example, the cooperative will plant soil environment, seeds and seedlings, use of water, fertilizer and medicine, planting / harvest time, etc. The transaction information of the farming process includes seed price, purchase source, fertilizer price, purchase source, pesticide price, purchase source and labor cost, etc. The primary processing link includes: environmental sanitation requirements, processing technology, equipment used, packaging type, etc. The transaction information of the processing process includes labor cost, input price and purchase source, etc. Brand operator labeling information, product batch, etc. It also includes key information such as warehousing logistics and sales environment. Data storage adopts a combination of blockchain and database storage. The database system stores pictures and a large amount of information, and the information summary hash value is stored in the blockchain. Then, the required smart contract is accessed through the smart contract retrieval submodule to upload information data and check the uploaded information data. Finally, the smart contract execution submodule is used to automatically execute the accessed smart contract and make an execution result.

[0047] The contract execution result acquisition and recording submodule in the supervision and management unit acquires and records the results after the contract execution submodule automatically executes the accessed smart contract and makes the execution result. At the same time, the node quality inspector online acquisition record submodule acquires and records the results of whether the quality inspectors of each node go on the chain to conduct supervision at the chain supervision time specified in the contract. Then the node credit value evaluation submodule acquires the smart contract execution results of each node within a period of time and whether the quality inspectors of each node go on the chain to conduct supervision at the chain supervision time specified in the contract, and analyzes the above obtained results to obtain the credit value X of each node:

[0048] X=(∑ n＝1 (if(r n =1,5,0))+Σ k＝1 (if(o k =1,5,0)))·μ

[0049] Among them, r n is the result of the smart contract execution of each node every n times within a period of time. When the node quality information is fully entered, r n =1, otherwise r n =0; if(x,y,z) means that when condition x is met, result y is returned, otherwise result z is returned; o k It is the result of each node quality inspector going online for supervision at the on-chain supervision time specified in the contract within a period of time. When the node quality inspector goes online for supervision at the on-chain supervision time specified in the contract, then o k =1, otherwise ok =0; μ is the pre-set conversion coefficient of the credit value, μ=0.1. Then, the supervision plan formulation module formulates a corresponding supervision plan for each node according to the credit value of each node. The higher the node credit value, the more lenient the supervision plan formulated for the corresponding node. Conversely, the lower the node credit value, the stricter the supervision plan formulated for the corresponding node.

[0050] When quality problems occur, the blockchain ledger viewing and downloading submodules in the quality traceability unit can provide each user with the right to access data. Users can view or download blockchain ledger information within their authority. The traceability information query submodule can quickly query all quality information by keyword or timestamp. The quality responsibility identification submodule can verify the digital signatures of relevant personnel to ensure the accuracy and effectiveness of information records and ensure accurate accountability.

[0051] Finally, integrate the blockchain network system and the Web software application system, complete the system's module testing and overall testing, modify system bugs, enrich system functions, and form a blockchain system that can be promoted and applied.

[0052] The electrical components that appear in this article are all electrical components that exist in reality.

[0053] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
