Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for tracing to a source of a drug based on a block chain according to an embodiment of the present application, which is applicable to a situation of tracing to a source of a drug based on a block chain, and is used to solve a problem that an existing drug tracing system is difficult to cooperatively process multi-party data of a drug in a circulation process, and the real effectiveness of drug circulation information cannot be guaranteed. The applicable blockchain may be, for example, a federation chain. The method may be performed by a blockchain-based drug tracing apparatus, which is implemented in software and/or hardware, and is preferably configured in an electronic device, such as a computing device carrying blockchain nodes.
As shown in fig. 1, the block chain-based drug tracing method is performed by block chain nodes, and specifically includes the following steps:
s110, acquiring a drug production information uplink transaction request initiated by a drug manufacturer user in a block chain network, and executing the drug production information uplink transaction request.
Specifically, a drug manufacturer is a source of drug transfer information, and when a household of the drug manufacturer starts to produce a drug, a drug information uplink request can be sent to a corresponding blockchain network, and drug production information is uploaded to a blockchain. The drug production information comprises drug names, production time, production line codes, production operator information, drug delivery date, delivery quantity, delivery destination, delivery units and the like. The blockchain-based drug traceability system responds to the chain transaction request of the drug production information and executes the request to store the corresponding drug production information to the corresponding location.
S120, acquiring a medicine warehouse-in/out information uplink transaction request initiated by a medicine dealer user in the blockchain network, and executing the medicine warehouse-in/out information uplink transaction request.
After the drug production factory finishes producing the drugs, the drugs are sent to a drug distributor, and the drug distributor records the warehousing-in record of each drug and the warehousing-out record of each drug. The warehousing record comprises information such as medicine names, medicine quantity, medicine manufacturer names and the like, and can also comprise warehousing position information after the medicines are warehoused. The delivery information includes information such as the name of the medicine, the number of deliveries, the destination of the delivery, and the carrier.
When a medicine dealer party generates a piece of medicine warehouse-in/out information, a medicine dealer user logs in a medicine traceability system, initiates a medicine warehouse-in/out information uplink request to a block chain network, and uploads the medicine warehouse-in/out information of each medicine to a block chain. And the medicine traceability system based on the block chain responds to the chain transaction request of the medicine in-out warehouse information, executes the request, and uniformly stores the corresponding medicine in-out warehouse information and the corresponding medicine production information, namely updates the state information of medicine circulation.
S130, acquiring a drug sales information uplink transaction request initiated by a pharmacy user in the blockchain network, and executing the drug sales information uplink transaction request.
After the medicines are sold by the dealers, the medicines are transferred to various pharmacy selling the medicines, and when a new medicine enters the pharmacy or a consumer purchases the medicine, the pharmacy has corresponding recorded information, sends a medicine sales information uplink request to the blockchain network, and stores the medicine sales information in the blockchain.
And the block chain-based drug traceability system responds to the drug sales information chain transaction request, executes the request, and uniformly stores the corresponding drug sales information chain transaction request, the corresponding drug production information and the drug in-out and in-out information, namely updates the state information of drug circulation.
S140, acquiring a medicine transportation information uplink transaction request initiated by a logistics company user in a block chain network, and executing the medicine transportation information uplink transaction request.
The logistics company, i.e., the carrier of the drug during circulation, is responsible for transporting the drug from the drug manufacturer to the drug distributor, or from the drug distributor to the drug store, and from the drug store to the consumer. When the medicine needs to be circulated, the logistics company uploads the medicine transportation information to the block chain. The medicine transportation information includes information such as medicine name, medicine quantity, transportation origin, destination, and transportation transfer station.
It should be noted that step S140 does not have to be in a strict sequence with steps S120 and S130, and the drug delivery information is generated when the drug is delivered from the drug manufacturer to the drug distributor or from the drug distributor to the drug store. Only for the same medicine, corresponding medicine warehouse-in and warehouse-out information, medicine sales information and medicine transportation information exist after the medicine production information exists. Further, when a drug has just completed the manufacturing process and another drug may have been shipped to a pharmacy, the progress of the drug circulation process for different types of drugs or different batches of drugs may not be the same.
In one embodiment, the drug may be sold directly from the manufacturer to the pharmacy, and the drug may not have drug warehousing information corresponding to the drug dealer user.
S150, acquiring a drug information query transaction request of a drug supervision user, executing the drug information query request, and querying and feeding back related drug information of a target drug in a block chain network, wherein the drug information comprises at least one of drug production information, drug warehouse-in and warehouse-out information, drug sales information and drug transportation information.
When the blockchain stores the related information of the medicine, the medicine supervision user can inquire the related information of the medicine through the blockchain network, and the inquired information can be information of any stage in the medicine circulation process. Similarly, the steps and the above steps S110 to S140 are not strictly limited in sequence, and the drug administration user may query the information of the target drug at any time when needed, and the target drug may not be shipped or may be in transit, and the serial numbers are only for convenience of description.
Further, the structure of the block chain-based drug traceability system in this embodiment may refer to the structure shown in fig. 2, where the system includes block chain nodes such as drug manufacturers, drug distributors, drug stores, and logistics companies, and each node may send an information uplink request to the block chain-based drug traceability system to upload corresponding drug information. Before that, the blockchain-based drug traceability system also acquires a drug manufacturer user, a drug distributor user, a drug store user, a logistics company user and a drug supervision user, registers a transaction request for an account in a blockchain network, executes the account registration transaction request, and distributes a public key and a private key of the account for the drug manufacturer user, the drug distributor user, the pharmacy user, the logistics company user and the drug supervision user. Then, when each node user sends a transaction request to the blockchain-based drug traceability system, the blockchain-based drug traceability system performs identity authentication on the user who sends the transaction request based on the public key and the private key; the business request comprises at least one of a drug production information uplink business request, a drug warehouse-in and warehouse-out information uplink business request, a drug sales information uplink business request, a drug transportation information uplink business request or a drug information inquiry business request, and correspondingly, the user comprises at least one of a drug manufacturer user, a drug distributor user, a pharmacy user, a logistics company user and a drug supervision user.
In a preferred embodiment, the drug manufacturer users, drug distributor users, pharmacy users, logistics company users, and drug administration users may establish a connection with the blockchain network via the electronic administration code of the target drug and issue a corresponding transaction request. As shown in fig. 3, after a user of a drug manufacturer, a user of a drug distributor, a user of a drug store, and a user of a logistics company log in a block chain-based drug traceability system, corresponding information can be stored in a corresponding position by scanning an electronic supervision code in a two-dimensional code form, so that the circulation information of the same drug is stored in the same position. As shown in fig. 4, a drug administration user can scan the administration code to query the information of the drug corresponding to the administration code to the blockchain-based drug traceability system, so as to realize drug traceability.
The electronic supervision code of the medicine is an identifier given to each product by an official party implementing electronic supervision on the product. The electronic supervision code of each product is unique, namely one code, is like the identity card of a commodity, and is called the supervision code for short. The electronic supervision code can establish a corresponding relation with the commodity code to complete the function of settlement and pricing in the retail field. Production enterprises transmit source information of production, quality and the like of products to a monitoring network database through electronic monitoring codes, circulation enterprises perform goods feeding inspection and acceptance through the electronic monitoring codes and transmit goods feeding information to the monitoring network database, and sales information is transmitted to the monitoring network database during sales, and the data information can be used for consumers to perform true and false and quality inquiry, governments to perform law enforcement and false forging, quality tracing and product recall management, and the enterprises can know market supply and demand conditions, channel sales conditions and fake related information.
According to the technical scheme of the embodiment, by utilizing the block chain technology, a medicine manufacturer, a medicine distributor, a pharmacy user, a logistics company and a medicine supervision user cooperate in multiple ways, information in links of medicine production, medicine circulation, medicine sale, logistics distribution and the like is stored in the block chain, all the parties maintain the block chain system together, data cannot be changed randomly, and the medicine supervision user can trace the source of the target medicine in the whole process.
