[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] Some embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0023] Figure 1 A schematic diagram of a process flow of a blockchain-based Chinese medicine traceability method provided in an embodiment of the present application. Certain input parameters or intermediate results in the process allow manual intervention and adjustment to help improve accuracy.

[0024] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.

[0025] Figure 1 The process in may include the following steps:

[0026] S101: Identify and encode the container containing the Chinese medicine to generate a first identification code for the Chinese medicine; wherein the same container contains the same type of Chinese medicine, and the planting environment of the Chinese medicine is the same.

[0027] That is to say, each container is labeled with its own identification code, there is only one type of Chinese medicine in a single container, and the Chinese medicine in a single container is purchased from the same production site. This enables the classification of Chinese medicine at the smallest granularity, which can facilitate the traceability of Chinese medicine in the later stage.

[0028] S102: Obtain the planting information of the traditional Chinese medicine through the supplier node, associate the first identification code with the planting information, and upload the associated planting information to the blockchain.

[0029] In some embodiments of the present application, since the planting information has a great influence on the growth process of Chinese medicine, it will affect the quality of Chinese medicine. Therefore, the more the planting information conforms to the growth conditions of Chinese medicine, the better the quality of Chinese medicine will be. Based on this, poor quality Chinese medicine can be screened out by screening unqualified planting information.

[0030] Specifically, first, through the smart contract in the blockchain, in the preset Chinese medicine planting database, according to the type of Chinese medicine, the associated planting information is matched with the standard planting information in the Chinese medicine planting database. Among them, the standard planting information refers to the planting information suitable for the growth of Chinese medicine released by planting experts. In other words, the closer the planting information is to the standard planting information, the better the quality of the Chinese medicine.

[0031] It should be noted that in the Chinese medicine planting database, standard planting information corresponding to different types of Chinese medicines is pre-stored.

[0032] Then, it is determined whether the associated planting information matches the standard planting information in the traditional Chinese medicine planting database. If so, the associated planting information is written into the block of the blockchain.

[0033] If not, the unmatched planting information is determined. Then, the medicinal value information of the traditional Chinese medicine is obtained. The medicinal value information is used to indicate the treatment information of the specified disease by the specified components of the traditional Chinese medicine.

[0034] When obtaining the medicinal value information of the traditional Chinese medicine, the medicinal value information of the traditional Chinese medicine is called in the preset medicinal value library according to the type of the traditional Chinese medicine. It should be noted that the preset medicinal value library includes medicinal value information corresponding to multiple types of traditional Chinese medicine.

[0035] Then, the impact level of mismatched planting information on the TCM is determined based on the growing conditions of the designated ingredients during the life cycle of the TCM.

[0036] Among them, when determining the impact level of mismatched planting information on traditional Chinese medicine, first, the designated components of the traditional Chinese medicine are determined based on the medicinal value information. Then, the corresponding growth conditions of the designated components in the production cycle of the traditional Chinese medicine are determined, for example, through the Internet, the growth conditions required for the designated components published by planting experts are obtained. It can be understood that the growth conditions also refer to the planting information.

[0037] Finally, the impact level of mismatched planting information on traditional Chinese medicine was determined based on the matching relationship between mismatched planting information and growth conditions.

[0038] When determining the impact level of mismatched planting information on traditional Chinese medicine, the growth factors included in the mismatched planting information are matched with the growth factors included in the production conditions to determine a matching growth factor pair. The growth factors include sunlight conditions, soil conditions, atmospheric conditions, water quality conditions, etc.

[0039] Then, according to the number of growth factor pairs, the impact level corresponding to the mismatched planting information is determined; wherein, the greater the number of growth factor pairs, the greater the impact level.

[0040] If the impact level is greater than the preset level, the unmatched planting information is cleared from the associated planting information to obtain valid associated planting information, which is then written into the block. If the impact level is less than or equal to the preset level, the unmatched planting information is also written into the block.

[0041] S103: Obtain the first transportation information of the traditional Chinese medicine, associate the first identification code with the first transportation information, and upload the associated first transportation information to the blockchain.

[0042] S104: Identify and encode the smallest packaging layer of the processed traditional Chinese medicine at the production node to generate a second identification code for the traditional Chinese medicine.

[0043] It is understandable that due to the characteristics of Chinese medicine itself, Chinese medicine is usually in bulk in the container. Then, when it arrives at the production node, the production party usually processes the bulk Chinese medicine and then continues to package it. Therefore, in order to facilitate traceability, a second identification code is given to the Chinese medicine at the smallest packaging layer.

[0044] S105: Associating the first identification code with the second identification code.

[0045] By associating the first identification code with the second identification code, code-to-code association is achieved, opening up the traceability channel for the raw materials.

[0046] S106: Obtain processing information of the traditional Chinese medicine through the production node, associate the second identification code with the processing information, and upload the associated processing information to the blockchain.

[0047] S107: Obtain the second transportation information of the Chinese medicine to the corresponding seller node, associate the second identification code with the second transportation information, and upload the associated second transportation information to the blockchain, so that the consumer node can scan the second identification code through a scanning device to obtain the associated planting information, the associated first transportation information, the associated processing information and the associated second transportation information of the Chinese medicine from the blockchain.

[0048] In some embodiments of the present application, after the associated second transportation information is uploaded to the blockchain, when quality problems occur in the traditional Chinese medicine, in order to promptly check whether there are problems in each link, the seller's node may frequently check the traceability information of the traditional Chinese medicine in a short period of time.

[0049] Based on this, it is possible to obtain the access request initiated by the seller node by scanning the second identification code, obtain the frequency of the seller node access request within a preset period, and determine whether the frequency exceeds the access threshold through the preset access smart contract.

[0050] If yes, it is determined that the Chinese medicine has the possibility of being potentially unqualified, and the supplier node is notified to conduct quality inspection on the Chinese medicine. If no, it means that the Chinese medicine does not have the possibility of being potentially unqualified, and no notification information is sent to the supplier node.

[0051] In some embodiments of the present application, when uploading the associated planting information, the associated first transportation information, the associated processing information, and the associated second transportation information to the blockchain, in order to store more efficiently and respond to the needs of each node in a timely manner, first, the basic information corresponding to the associated planting information, the associated first transportation information, the associated processing information, and the associated second transportation information is determined, and the basic information is written into the block body. The basic information is related to the identity of each node and the type of each information.

[0052] Then, the summary information corresponding to the associated planting information, the associated first transportation information, the associated processing information, and the associated second transportation information is generated respectively. Then, the corresponding summary information is stored in a pre-constructed distributed database. In the distributed database, the supplier node, the production node, and the seller node correspond to different databases respectively;

[0053] Finally, a mapping relationship between the distributed database and the block body is established, and the mapping relationship is written into the block header so that the data mapping can be recorded in the block header. Through the mapping relationship, the corresponding information can be obtained from the distributed database.

[0054] This enables basic information to be stored in the block body. The data information generated during the operation of the blockchain is stored in a database outside the main chain in the form of a summary, and is stored in a classified form to facilitate traceability and data analysis. The data mapping is recorded in the block header.

[0055] Furthermore, each database in the distributed database has a multi-level storage structure, and stores the corresponding summary information in a pre-built distributed database, specifically including:

[0056] First, the summary information and the storage time of the summary information are obtained, and the summary information is stored in the first level of the corresponding database; wherein the database is divided into multiple levels in sequence according to the preset data capacity, and the capacity of the first level is lower than that of other levels;

[0057] Then, if the storage duration of the summary information exceeds the preset time limit, the summary information is backed up and stored in the second level; the first level is lower than the level of the second level;

[0058] Finally, in the first level, a backup link of the summary information is generated, and the summary information is cleared, so that the summary information is backed up level by level, thereby enabling more efficient storage.

[0059] In some embodiments of the present application, when the supplier node, the producer node, and the seller node apply to go online, an asymmetric encryption public key and private key pair are generated for each node, taking the supplier node as an example.

[0060] First, a hash calculation is performed on the associated planting information to obtain a first hash value, and the first hash value is digitally signed by a private key corresponding to the supplier; wherein the public key is used to verify the digitally signed first hash value.

[0061] Then, the public key is hashed to obtain a second hash value, the second hash value is associated with the associated planting information, and the identity number of the supplier node is generated through the second hash value;

[0062] Finally, the first hash value of the digital signature and the identity number of the supplier node are uploaded to the blockchain through the supplier node and broadcasted to the entire network, thereby achieving fair and equitable supply and demand transactions and providing real data to support decision-making and business evaluation.

[0063] It should be noted that although the embodiments of the present application are based on Figure 1 Steps S101 to S107 are described in sequence, but this does not mean that steps S101 to S107 must be performed in a strict order. Figure 1 The order shown in the figure is to introduce and explain step S101 to step S107 in sequence, in order to facilitate those skilled in the art to understand the technical solution of the embodiment of the present application. In other words, in the embodiment of the present application, the order between step S101 to step S107 can be appropriately adjusted according to actual needs.

[0064] pass Figure 1 The method uses identification to break the information silos between Chinese medicine planting, circulation, and production, realizes information interaction, collaborative operation, and data sharing between upstream and downstream enterprises, improves enterprise production efficiency, and reduces the cost of enterprise supply and demand docking. Ultimately, in the Chinese medicine production process, through the docking of the identification resolution system with industrial software, it collects information such as raw material procurement, circulation, and production, and realizes the full life cycle control of Chinese medicine manufacturing from raw material planting, circulation, to Chinese medicine production.

[0065] Based on the same idea, some embodiments of the present application also provide devices and non-volatile computer storage media corresponding to the above methods.
