Number.
In device of the present invention, the Query Result comprises at least medicine source and whether corresponding medicine has been sold
Go out information.
Implement distributed the medicine source tracing method and device based on block chain of the present invention, have the advantages that：By
Medicine is manufactured in chemical manufacturing plant；When medicine dispatches from the factory, pass through the adhesive label progress uniqueness mark on medicine；Label is got the bid
It is marked with company-information；Chemical manufacturing plant is circulated in the medicine before link, by way of scanning label, by label
Uniqueness markup information writes block chain, and the uniqueness markup information that block chain is preserved by algorithm of knowing together is synchronized to other
Node；After medicine dispatches from the factory, the last related circulation channel information write area for selling shops will be reached by multiple dealers
Block chain is preserved；Information inquiry APP that sufferer passes through mobile terminal or other means scans label, and connects the progress of block chain
Inquiry, block chain can realize that distributed medicine traces to the source, can reduce doctor to sufferer feedback query result by block chain
Suffer from contradiction.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the flow of method in distributed medicine source tracing method and device one embodiment of the present invention based on block chain
Figure；
Fig. 2 is the structural representation of device in the embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
In distributed medicine source tracing method of the present invention based on block chain and device embodiment, its point based on block chain
The flow chart of cloth medicine source tracing method is as shown in Figure 1.In Fig. 1, being somebody's turn to do the distributed medicine source tracing method based on block chain includes
Following steps：
Step S01 chemical manufacturing plants manufacture medicine：In this step, chemical manufacturing plant is according to normal flow manufacturing medicine.
Step S02 passes through the adhesive label progress uniqueness mark on medicine when medicine dispatches from the factory：In this step, work as medicine
When product dispatch from the factory, pass through the adhesive label progress uniqueness mark on medicine.Above-mentioned label can be RFID, bar code or Quick Response Code
Deng being labeled with company-information in label, company-information comprises at least trade name, nomenclature of drug and lot number.
Step S03 chemical manufacturing plants are before medicine circulates link, by way of scanning label, by label only
One property markup information writes block chain, and the uniqueness markup information that block chain is preserved by algorithm of knowing together is synchronized to other sections
Point：In this step, chemical manufacturing plant is circulated in medicine before link, will be unique in label by way of scanning label
Property markup information write-in block chain, block chain is distributed system in itself, there may be multiple nodes, shape between this multiple node
Into a closed loop.In addition, in this step, uniqueness markup information that block chain is preserved by algorithm of knowing together is synchronized to other
Node.Which both ensured information can not tamper, information is also distributed in different places, when can balance subsequent query
Pressure.Therefore by block chain can ensure information can not distort and distributed deployment.
Step S04 will reach the last related circulation for selling shops by multiple dealers after medicine dispatches from the factory
Information write-in block chain is preserved：In this step, after medicine dispatches from the factory, it may can just be reached by multiple dealers last
Shops is sold, therefore the last related circulation channel information write-in for selling shops will be reached by multiple dealers in this step
Block chain is preserved.
Information inquiry APP that step S05 sufferers pass through mobile terminal or other means scans label, and connects block chain and enter
Row inquiry, block chain is to sufferer feedback query result：In this step, information inquiry APP or other that sufferer passes through mobile terminal
Mode scans label, then connects block chain and is inquired about, and block chain is at least wrapped in Query Result to sufferer feedback query result
Include medicine source and whether corresponding medicine has sold information etc., so as to make sufferer confirm the reliability of medicine.In the present embodiment
Method in, realize that distributed medicine is traced to the source by block chain, conflict between doctors and patients can be reduced.
The present embodiment further relates to a kind of device for realizing the above-mentioned distributed medicine source tracing method based on block chain, its structure
Schematic diagram such as Fig. 2 institutes.In Fig. 2, the device includes medicine manufacturing cell 1, mark unit 2, mark writing unit 3, circulation
