Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
A federation chain, belonging to one of the block chains, refers to members and limited third parties for a particular group, internally designating a plurality of preselected nodes as billers, the generation of each block being determined by all the preselected nodes together, and other access nodes can trade without asking for a billing process. Compared with a common blockchain, the alliance blockchain has more advantages in efficiency and flexibility: 1. the method still has the characteristic that the inbound block cannot be illegally tampered; 2. the transaction cost is lower, and the transaction can be verified only by a limited and high-calculation third-party node without whole-network confirmation; 3. the efficiency of node maintenance is higher.
Corresponding to the application of the alliance chain in the invention, the limited third party in the alliance chain, namely the supervision node, corresponds to the trusted third party supervision authority and can be any trusted authority which has supervision capacity on the safety quality of the dairy product; in the invention, the data entering chain does not need to be verified by each node, but can be entered after being verified by limited supervision nodes, so that the chain entering efficiency is greatly improved. Meanwhile, the alliance chain allows any authorized node to join the network, such as an authorized first node, an authorized second node, a transportation node and the like, and respectively corresponds to each entity operation stage of the whole life cycle of the dairy product, which is consistent with that each node in the alliance chain is usually corresponding to an entity organization point; in addition, in the invention, any user can enter the network to interact with other nodes after scanning the specific code.
Example one
Referring to fig. 1 and fig. 2, the present embodiment provides a dairy product tracing management method based on a block chain, which can implement a production process of any person traceable to a dairy product through a two-dimensional code of a dairy product external package.
Corresponding to each dairy animal, unique corresponding RFID label information is configured, and basic information including identity information and the like of the corresponding dairy animal is recorded in the RFID label information. The identity information may be in the form of a code or the like, which uniquely identifies the dairy animal. The RFID tag information will be provided on the dairy animal in a manner that is not easily detachable. For example, the RFID tag is formed as an ear tag that is attached to the ear of a dairy animal. The RFID tags on the dairy animals will be identified and registered prior to entering the link corresponding to each node, thereby associating link operation content with the dairy animal.
Corresponding to each link of the dairy production stage, the first node which is authorized in the block chain is used. The first node set at least comprises a feeding node, a medication node, an epidemic prevention node and a killing node. Obviously, the feeding node corresponds to a feeding link of the milk producing animal, the medicine taking node corresponds to a medicine taking link of the milk producing animal, the epidemic prevention node corresponds to a health epidemic prevention link of the milk producing animal, and the disinfection node corresponds to a disinfection and sterilization link of the milk producing animal. In this example, much attention is paid to the quality of the source of the milk, i.e. the health of the milk producing animal. The monitoring of the whole production link from a dairy product production body to before dairy product filling is realized, and the quality of the source is really controlled.
And the entity hardware equipment corresponding to each first node is provided with a camera, an RFID tag reader and a processor. The RFID tag reader is used for identifying and reading RFID tag information configured on the dairy animal entering a link corresponding to the current first node; the camera is used for monitoring the operation process of the corresponding link; the processor is used for optimizing the shot video and establishing the association relationship between the read RFID label information and the read shot video. The video optimization processing comprises video preprocessing and key information extraction, wherein the preprocessing comprises denoising processing, image quality optimization and other processing for improving the video image quality; the key information extraction refers to extracting key pictures, deleting invalid pictures, wherein the invalid pictures comprise fuzzy pictures generated by quick shaking, pictures of non-dairy animals with focuses and the like, and the key pictures are pictures directly related to corresponding links, such as feed putting pictures, medicine taking pictures and the like. By optimizing the video, invalid information can be filtered, key information is mainly reserved, and the video recording time is greatly shortened.
In a specific example, the camera of the feeding node will take pictures of the lower dairy animals including feed delivery and daily activity operations; the camera in the medicine taking link is used for shooting the daily health inspection process and the medicine taking process of the dairy animals each time, and the key shooting process comprises medicine focusing confirmation and actual medicine taking operation.
Each first node acquires traceability information, wherein the traceability information comprises RFID label information of the dairy animal, video of the dairy animal in a link corresponding to the current first node and time record. The time record refers to the time record of the first node receiving the tracing information; the video of the dairy animal in the link corresponding to the current first node, for example, the video of a cow (corresponding to RFID tag information) eating grass.
In a specific example, dairy-based animals are typically characterized by being colonized and by the wide enough field of view of today's cameras. At a particular node, for example a feeding node, milk producing animals are always eating and moving collectively. For the specific nodes, the milk producing animals which go into the mirror can be determined according to the RFID label information read by the RFID label reader, and the video of one section of multi-head milk producing animals which go into the mirror at the same time is used as the video of each milk producing animal in the mirror corresponding to the same link. For example, a video recording of 5 cattle eating the feed together is shot by the camera, and the 5 cattle read corresponding RFID tag information before entering the shooting visual field, so that the video recording can be submitted as the traceability information of the corresponding feeding nodes of the 5 cattle respectively. Therefore, the focusing and video recording of each dairy animal are not needed, and the shooting contents are basically consistent. This releases much pressure to the camera and the processor, and meanwhile, the understanding of the performance of the dairy animals in the corresponding links is not influenced.
After receiving the tracing information, each first node needs to store it into the blockchain. In this embodiment, it will be stored by a limited number of supervisory nodes to ensure its security. The supervision node corresponds to a third-party supervision organization, such as a trusted dairy product quality supervision department like a dairy product industry administration department in a location. The supervision node in the block chain of this embodiment prestores the dairy animal videos corresponding to the information of each RFID tag. The dairy animal video refers to a video recording of a close-up of a certain dairy animal (assumed to be dairy animal a) for matching with the video in the traceability information, and determining whether the dairy animal in the video recording is dairy animal a or contains dairy animal a.
Specifically, after receiving a registration request sent by any first node, any supervision node analyzes the registration request to obtain corresponding tracing information. Then, inquiring a database according to RFID label information in the tracing information, and acquiring a pre-stored dairy animal video corresponding to the RFID label information; then, according to the dairy animal video, carrying out identity verification on the dairy animals in the video in the tracing information; if the verification is not passed, rejecting the registration request; and if the verification is passed, storing the tracing information, and entering the next step. Therefore, after receiving the information to be traced, the supervision node firstly verifies whether the corresponding relation between the video object in the tracing information and the alleged RFID label information is correct, if the video recorded in the tracing information is indeed the dairy animal corresponding to the RFID label information in the tracing information, the video is proved to be effective, the corresponding relation is correct, and the video can be stored as the tracing information of the dairy animal corresponding to the current node. It should be noted that, in this embodiment, the reason why the supervision node recognizes the validity of the traceability information only by verifying the identity of the milk-producing animal in the video, and does not need to verify the content of the video, is that the video in the traceability information uploaded by the first node is directly obtained by the corresponding first node, and is not transmitted, so that the supervision node is worthy of trust.
After the supervision node verifies that the identity of the milk-producing animal in the video passes, the traceability information is stored locally, and whether the corresponding first node is a killing node or not, namely whether the first node is the last link of the production stage or not, is further judged. The purpose of doing so is to realize the integration, packaging and chaining of the staged tracing information, and through the integration of the information, the subsequent inquiry and the acquisition of all the information in the whole production stage are facilitated.
And if the first node corresponding to the currently received tracing information is a killing node, the milk produced by the dairy animal is proved to have ended the production stage, and then packaging and the like are carried out. The health of the milk production body in the production stage, the milk processing mode and the processing conditions directly influence the quality of the finished milk product, so that the production stage of the milk is particularly critical and is the most important stage in the milk supply chain which is easy to cause quality problems. Therefore, it is necessary to separately integrate the traceability information of the milk production stage so that the supervisor or the consumer can trace the source flow of the milk in a targeted manner.
Specifically, if it is determined that the first node corresponding to the currently received tracing information is not a killer node, the received tracing information is broadcasted to other supervisory nodes for storage. In this case, the tracing information is stored in each supervision node in a distributed manner, so that any node is ineffective in modifying the tracing information, and the safety of the tracing information is guaranteed. If the first node corresponding to the currently received tracing information is judged to be a killing node, the supervision node firstly acquires the tracing information of each corresponding first node according to the RFID label information in the tracing information. The traceability information obtained here refers to the set of traceability information of the dairy animals identified by the RFID tag information in each link of the whole production stage. No matter which supervision node receives the effective tracing information uploaded by any first node, the effective tracing information is broadcasted to other supervision nodes, so that each supervision node stores all the tracing information uploaded by any first node, and the acquisition of the set of the tracing information is feasible. Then, the supervision node generates a two-dimensional code corresponding to the RFID tag information according to the obtained (set of) traceability information and the current time. That is to say, all the traceability information of each dairy animal in the production stage corresponds to each dairy animal through a two-dimensional code. Then, the supervision node packages the generated two-dimensional codes and the traceability information corresponding to each first node (i.e. all traceability information of the dairy animal in the production stage) into traceability blocks. In addition, the tracing block is broadcasted to other supervision nodes, and the security of the tracing block is ensured through the chaining of the tracing block, so that the tracing block cannot be tampered.
And storing a first association relation between each tracing block and the corresponding two-dimensional code. Since the two-dimensional code also uniquely corresponds to the RFID tag information, the first association relationship may be understood as recorded as: relation between dairy animals, the tracing blocks and the two-dimensional codes.
Therefore, the live records of the corresponding dairy animals in all links of the whole production stage can be easily associated through the two-dimensional code.
In actual application, N bottles of dairy products can be obtained according to the milk produced by one dairy animal, namely, one dairy animal corresponds to N bottles of dairy products. And the two-dimensional code corresponding to the RFID label information corresponding to the dairy animal is obtained from the supervision node according to the corresponding relation, and then the two-dimensional code is jet-printed on the outer package of the dairy product through the package node (namely, the second node), so that the creation of the traceability way of a single dairy product finished product is completed. Whether the dairy product is a consumer or a supervision party, the image records of the dairy animals in all links from feeding to milking and then before packaging can be traced back through the two-dimensional code on any dairy product finished product outer package, so that the quality of the dairy product is guaranteed to be over-standard.
In a specific example, after scanning the two-dimensional code, any intelligent terminal requests any supervision node to acquire a corresponding tracing block; the supervision node acquires a source tracing block corresponding to the two-dimensional code according to the first incidence relation and sends the source tracing block to the intelligent terminal; the intelligent terminal analyzes the tracing block to obtain tracing information; the tracing information comprises video of each link of the corresponding dairy animal in the whole production stage. Optionally, all the videos are partitioned according to links, and then each video is sequenced according to time conditions and displayed to a user; optionally, all the videos are directly sorted according to the time sequence, and are displayed to the user. And the intelligent terminal plays the corresponding video in the corresponding tracing information according to the selection of the user. For example, the consumer can directly click the video in the killing link on the intelligent terminal to know the killing process of the dairy product, and the current killing process of the dairy product is known through the video information.
Example two
Referring to fig. d, the present embodiment is further extended on the basis of the first embodiment to implement monitoring of the whole life cycle of the dairy product.
The method of this example also monitors the packaging stage after the production stage described in example one. The method comprises the following steps:
the packaging stage corresponds to a second node; the second node comprises a filling node and a packaging node. The physical hardware device corresponding to the second node is also provided with a camera and a processor. Wherein, when the filling node is filling, will acquire the video recording of filling process through the camera to two-dimensional code and the only identification code (dairy products identification) that the dairy products that definitely the filling obtained correspond. Regarding the latter, the filling node performs related marking on dairy products obtained by filling the milk produced by the same dairy animal, and the marking objects are RFID label information corresponding to the dairy animal and a unique identification code of the dairy product; and then, acquiring the corresponding two-dimensional code according to the RFID label information, so that the association relation between the RFID label information, the two-dimensional code and the unique dairy product identification code can be determined. And the packaging node prints the two-dimensional code on the corresponding outer package of the dairy product by spraying according to the association relationship, and packages the two-dimensional code into a box to obtain the relationship between the unique identification code and the box code of the dairy product, and meanwhile, the video of the dairy product package is synchronously shot and obtained. Through the second node, the association relationship between the two-dimensional code and the unique identification code of the dairy product can be clarified and materialized, and meanwhile, a second association relationship between the RFID label information, the two-dimensional code, the unique identification code of the dairy product and the box code of the dairy product is established.
The second node acquires packaging information, wherein the packaging information comprises a two-dimensional code, a unique identification code and a box code corresponding to the dairy product, a video of the link corresponding to the current second node of the dairy product and a time record; then, the second node sends the package information to any supervision node; after the supervision node verifies that the received package information passes, the package information is stored locally and is broadcast to other supervision nodes. The verified contents comprise formats, unique dairy product identification codes and the like, and the purpose is to verify the validity of the packaging information.
Further, after the packing node, the present embodiment will also monitor the subsequent transportation phase. Specifically, the transportation node acquires transportation information, which includes transportation conditions, box codes and positioning information thereof. The physical hardware equipment corresponding to the transportation node can be transportation points arranged in various places, and the transportation information is acquired by the transportation points and then is sent to the transportation node; the transportation node is responsible for integrating the transportation information and then sending the transportation information to any supervision node for safe storage; for the supervision node, after the received transportation information is verified to be valid, the transportation information needs to be broadcast to other supervision nodes for storage.
And furthermore, after the packaging stage and the transportation stage are sequentially carried out, the integration of the whole life cycle pipeline data of the dairy product is triggered through warehousing of the information on shelves of the dairy product, the pipeline blocks are obtained through packaging, the pipeline blocks are merged into chain safe storage, and meanwhile, the convenience acquisition of the pipeline blocks is provided.
Specifically, after a box code is scanned and obtained through code scanning equipment connected with a block chain system, information on shelving of a dairy product corresponding to the box code is recorded in the system; after receiving the information on shelves, any supervision node can acquire transportation information corresponding to the box code according to locally stored transportation information; and then, respectively acquiring the two-dimensional code and the unique identification code associated with the box code by the supervision node according to the second association relation. Namely, the two-dimensional codes (one or more than two) corresponding to the box codes and the unique identification code set corresponding to the box codes are respectively obtained.
It should be noted that there are cases where one box code corresponds to more than two-dimensional codes, for example, a box of milk contains a bottle of boxed milk B produced by a cow B in addition to boxed milk a produced by a cow a, and different dairy animals correspond to different RFID tag information, and different RFID tag information corresponds to different two-dimensional codes. At this time, according to the box code, two or more two-dimensional codes associated with the box code (corresponding to the above example, the two-dimensional code corresponding to the cow a and the two-dimensional code corresponding to the cow B are obtained at the same time) are obtained.
Then, the supervision node acquires corresponding tracing blocks according to the two-dimension codes associated with the box codes (if more than one two-dimension code is available, the corresponding tracing blocks are acquired respectively); the supervision node acquires packaging information corresponding to each unique identification code from locally stored packaging information according to the unique identification code set associated with the box code; and the supervision node packs the acquired tracing block, the packaging information and the transportation information into a flow block and broadcasts the flow block to other supervision nodes. Therefore, the safe chain-entering storage of the pipeline blocks is realized, and the pipeline blocks can not be tampered through the chain-entering. In addition, a third association with the bin code and the pipeline block is established for reading.
The intelligent terminal requests any supervision node to acquire a flow block corresponding to the box code by scanning the box code; the intelligent terminal analyzes and obtains the running data (including the tracing block, the packaging information and the transportation information which are obtained simultaneously) according to the received running block, and then plays the video in the information according to the selection of the user.
Therefore, live monitoring of the whole life cycle of the dairy product and tracing of running water of the whole life cycle of the dairy product are achieved. As the monitoring mechanism serving as the monitoring node in the block chain directly participates in the generation of the related data of the source tracing, the data reliability is higher; meanwhile, certain constraint force can be generated for manufacturers to promote the quality safety of the milk control product; for consumers, the method has the advantages that the method is a way of independently tracing the production stage of the dairy products and a way of tracing the whole life cycle of the dairy products, and the consumers are relieved of the quality and drinking of the dairy products by using the video recording fact, so that the method is more favorable for dairy product popularization.
