[0026] In view of this, on the one hand, embodiments of the present invention provide a research and development material traceability management method, including: receiving purchased research and development materials, assigning a unique traceability code to each piece of research and development material; collecting complete data of each piece of research and development material, constructing a research and development material data management library including the traceability code, and recording the experimental flow data of the research and development materials; periodically extracting experimental result data from the experimental flow data, statistically analyzing abnormal experimental result data in the experimental result data that characterizes the abnormal disposal of the research and development materials, determining whether the number of abnormal experimental result data exceeds a preset threshold, and if so, extracting the traceability code of the research and development material involved in each abnormal experimental result data, and generating a traceability code set; analyzing whether there are any abnormalities in the batches of research and development materials involved in the traceability code set, obtaining anomaly analysis results; and outputting the anomaly analysis results.
[0027] The present invention provides a research and development material traceability management method that assigns traceability codes to research and development materials and associates them with the experimental process, thereby constructing a material traceability management system for the entire research and development process. This provides data support for tracing material problems during the research and development process, effectively saving the diagnostic and analysis process for research and development failures caused by material problems, significantly shortening the research and development cycle, and reducing trial and error costs.
[0028] In some embodiments, the research and development material traceability management method provided by the present invention can be executed by any electronic device 20 with data processing capabilities, such as a general-purpose computer, personal computer, laptop computer, switch or tablet computer, etc. The specific implementation of the electronic device 20 is not limited here.

[0030] Processor 210 may include one or more processing cores. Processor 210 connects to various parts within electronic device 20 using various interfaces and lines, and performs various functions and processes data of electronic device 20 by running or executing instructions, programs, code sets, or instruction sets stored in memory 220, and by calling data stored in memory 220. Optionally, processor 210 may be implemented using at least one of the following hardware forms: Central Processing Unit (CPU), Graphics Processing Unit (GPU), Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA).
[0031] The memory 220 may include random access memory (RAI) or read-only memory (ROI). Optionally, the memory 220 may include non-transitory computer-readable storage ledger. The memory 220 may be used to store instructions, programs, code, code sets, or instruction sets. The memory 220 may include a stored program area.

[0034] It is understood that the structure illustrated in this embodiment does not constitute a specific limitation on the electronic device 20. In other embodiments of the present invention, the electronic device 20 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.
[0035] The following description, in conjunction with the accompanying drawings, illustrates a research and development material traceability management method provided by an embodiment of the present invention.
[0036] like Figure 2 As shown, this embodiment of the invention provides a method for traceability management of R&D materials, which may include, but is not limited to: Step S1: Receive the purchased R&D materials, assign a unique traceability code to each piece of R&D material.
[0037] In the specific implementation process, R&D materials are usually purchased in batches according to experimental needs. Since a batch of purchased R&D materials may be quite large, in order to facilitate management, this embodiment of the invention assigns a unique traceability code according to the smallest packaging of the R&D materials.
[0038] In one feasible implementation, the method of assigning a unique traceability code to each piece of research and development material as described in this embodiment of the invention may include, but is not limited to: A multi-segment structure is adopted to assign a unique code to each of the aforementioned R&D materials, generating a unique traceability code.
[0039] In specific implementation, the multi-segment structure in the embodiments of the present invention may include, but is not limited to, [organization identification code], [material classification code], [cryptographically secure random number] and [verification code], to ensure the uniqueness and readability of the traceability code.
[0040] In one feasible implementation, after generating the unique traceability code, the embodiments of the present invention may, but are not limited to, further include: Collect key material information of the research and development materials, and use an encryption algorithm to perform encryption operations on the traceability code and the key material information to generate a digital tag.
[0041] In specific implementation, the key material information mentioned in the embodiments of the present invention may include, but is not limited to, batch number, production date, specifications, etc., and is not limited here. The encryption algorithm mentioned in the embodiments of the present invention may be, but is not limited to, national cryptographic algorithms (such as SM2) or RSA algorithms, and is not limited here.
[0042] In this embodiment of the invention, a digital tag is generated by combining the traceability code with the key information of the research and development materials through an encryption algorithm. The digital tag is bound to the traceability code, which can play an anti-counterfeiting role.
[0043] In the specific implementation process, after generating the traceability code, the embodiments of the present invention affix a QR code or UHF label containing the traceability code to the packaging of the research and development materials to complete the mapping from physical entity to digital identity.
[0044] Step S2: Collect complete data for each of the R&D materials, construct an R&D material data management library including the traceability code, and record the experimental flow data of the R&D materials.
[0045] In one feasible implementation, the collection of complete data for each piece of R&D material and the construction of an R&D material data management library including the traceability code, as described in this embodiment of the invention, may include, but is not limited to: Collect complete data of the R&D materials and store the complete data off-chain to obtain a unique content identifier; Construct a Merkle tree with the source code and the content identifier as its core; Write the root hash of the Merkle tree into the specified blockchain network.
[0046] In specific implementation, the complete data mentioned in the embodiments of the present invention may include, but is not limited to, basic information, key parameters, and qualification documents of the research and development materials. The basic information may include, but is not limited to, the name and specifications of the research and development materials; the key parameters may include, but are not limited to, purity, concentration, and pH value; and the qualification documents may include, but are not limited to, quality inspection reports and scanned copies of supplier qualifications, etc., without limitation.
[0047] In specific implementation, embodiments of the present invention may, but are not limited to, store the complete data in cloud storage or IPFS (InterPlanetary File System) to obtain a unique content identifier, such as a URL in cloud storage or a CID (digital fingerprint of a file) in IPFS.
[0048] In specific implementation, the Merkle tree in this embodiment of the invention may include batch, operation timestamp, and operation type, in addition to the two core data elements of the traceability code and the content identifier, without limitation.
[0049] This invention utilizes the immutability of blockchain to assign credible timestamps and proof of existence to all critical operations, providing sufficient credibility support for subsequent traceability of abnormal R&D materials.
[0050] In one feasible implementation, the recording of experimental flow data of the research and development materials in this embodiment of the invention may include, but is not limited to: According to the pre-set circulation rules, the circulation status of the R&D materials at each circulation node and the associated information of the circulation status are recorded.
[0051] In the specific implementation process, the embodiments of the present invention divide the life cycle of the research and development physical objects into multiple flow nodes such as coding, in stock, awaiting use, issued, in use, consumed, and discarded, and set conversion rules for each node. For example, the status change must be driven by scanning the traceability code, and some nodes must be forced to record related information, etc., which are not limited here.
[0052] In one feasible implementation, the associated information of the flow status in the embodiments of the present invention may include, but is not limited to, the experiment number, the experiment steps, and the amount of research and development materials used.
[0053] It should be noted that the experiment number, experimental steps, and R&D material usage in the embodiments of the present invention are only related information of the experiment-related nodes. The embodiments of the present invention can also set related information in other nodes, for example: Inbound: The warehouse manager scans the barcode, the status changes to "in stock", and records the storage location, environmental data, etc.; Issuance: The lab technician scans the code and submits the project number, and the status changes to pending issuance; after approval, the status changes to issued. Experiment usage: The experimenter scans the code, the status changes to "in use", and the experiment number, experimental steps and material usage are forcibly associated; Experiment End: After the experimenter confirms, the status changes to Consumed (normally used up) or Discarded (abnormally discarded, the reason must be filled in).
[0054] This invention provides data support for subsequent traceability analysis of experimental results by recording the circulation status of the research and development materials at each circulation node and the associated information of the circulation status.
[0055] Step S3: Periodically extract experimental result data from the experimental flow data, count the abnormal experimental result data in the experimental result data that represent the abnormal disposal of the R&D materials, determine whether the number of abnormal experimental result data exceeds a preset threshold, if so, extract the traceability code of the R&D materials involved in each abnormal experimental result data, and generate a traceability code set.
[0056] In the specific implementation process, the period for statistical analysis of the experimental flow data in this embodiment of the invention is determined according to the actual research and development situation. For example, time can be used as the period unit, such as 24 hours or 48 hours as a period for data statistics; of course, other period units can also be used, such as the experimental result quantity as the period unit, etc., which are not limited here.
[0057] In the specific implementation process, the experimental result data in the embodiments of the present invention shall be actively filled in or selected by the experimenter when the experiment ends and the experimental material status is changed. This may include, but is not limited to, filling in data that indicates normal consumption or data that indicates disposal due to abnormality of the research and development materials. No limitation is made here.
[0058] In specific implementation, the preset threshold in the embodiments of the present invention is determined according to actual needs, and is not limited here.
[0059] Step S4: Analyze whether there are any anomalies in the batches of R&D materials involved in the traceability code set, and obtain the anomaly analysis results.
[0060] In one feasible implementation, the analysis of whether there are any anomalies in the batches of R&D materials involved in the traceability code set, and the obtaining of anomaly analysis results, in this embodiment of the invention may include, but is not limited to: Calculate the frequency of each R&D material batch appearing in the abnormal experiment flow data of the current period in the traceability code set, and obtain the current period abnormal experiment usage frequency of each R&D material batch; The abnormality degree of the R&D material batch is obtained by comparing the frequency of the current cycle abnormal experiment with the average frequency of the historical cycle abnormal experiment. Determine whether the anomaly level is greater than a preset threshold. If so, record the R&D material batch as an abnormal R&D material batch and obtain the anomaly analysis result.
[0061] In the specific implementation process, the same batch of R&D materials may be used in multiple experiments. After obtaining the traceability code set, the R&D materials of the same batch, i.e. the R&D material batch, are extracted from the traceability code set and analyzed in a unified manner to calculate the frequency of the R&D material batch in the abnormal experimental flow data of the current period.
[0062] Step S5: Output the anomaly analysis results.
[0063] In one feasible implementation, the output anomaly analysis results described in this embodiment of the invention may include, but are not limited to: Output the abnormal R&D material batch and the experimental data related to the abnormal R&D material batch.
[0064] The above-mentioned R&D material traceability management method provided by the present invention assigns traceability codes to R&D materials and associates them with the experimental process to build a material traceability management system for the entire R&D process. It provides data support for tracing material problems in the R&D process, effectively saves the diagnostic and analysis process of R&D failures caused by material problems, significantly shortens the R&D cycle, and reduces trial and error costs.
[0065] It should be noted that, in addition to reverse traceability, the above-mentioned R&D material traceability management method provided in this embodiment of the invention can also receive forward query requests, display all status records of the entire life cycle of the R&D material through the traceability code, and list all associated experimental record sets.
