Description

Technical Field

[0001] This specification relates to the field of computer technology, and in particular to a traceability method, apparatus, equipment and medium for battery recycling. Background Technology

[0002] Used batteries are hazardous waste. If disposed of carelessly, the heavy metals and toxic waste liquids they release will severely pollute the environment and pose a serious threat to human health. Therefore, centralized recycling of used batteries, refining them into recycled lead, and promoting their reuse is the fundamental solution to this pollution problem. Used batteries contain a large amount of recyclable heavy metals and acids. For example, the recycling of lead-acid batteries mainly focuses on the reuse of waste lead, and also includes the utilization of waste acid and the plastic casing.

[0003] After being disposed of, the lead in used batteries can be completely recycled. Under traditional methods, the various processes of used battery recycling lack effective oversight and cannot be traced back to their origins. Therefore, more effective traceability methods for battery recycling are needed to strengthen the oversight of each process. Summary of the Invention

[0049] This specification provides a method, apparatus, equipment, and medium for tracing the origin of battery recycling through its embodiments.

[0050] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0051] Figure 1 This is a schematic flowchart illustrating a battery recycling traceability method provided in one or more embodiments of this specification. Certain input parameters or intermediate results in the process may be manually adjusted to help improve accuracy.

[0052] The method flow steps of the embodiments in this specification are as follows:

[0053] S102, during the production of the specified battery, a corresponding identification number is generated at the production process node, and the identification number is associated with the identification information of the specified battery.

[0054] In the embodiments of this specification, the identification information of a designated battery may include the product model, production date, battery capacity, and circulation information of the designated battery. An identity number for the designated battery can be generated through the identifier resolution code engine module. The identifier resolution code engine module has the characteristic of "heterogeneous code compatibility," obtaining a unique identity identifier for the product within the national identifier resolution system without affecting the designated battery manufacturer's own product identification and coding specifications, thus reducing the difficulty and cost of modifying product identifier resolution registration. That is, when an enterprise registers its enterprise and product code on the platform, the identifier resolution code engine module automatically binds an industrial internet identifier to that code, minimizing intrusion into the enterprise's existing systems, reducing modification difficulty, and increasing integration efficiency. At the designated battery production source enterprise, through the application for a product identifier number, an "ID card" is generated for each battery. The identification information corresponding to the ID card number can not only include information such as the product model, production date, and battery capacity of the designated battery, but also provide data maintenance and updates based on the identity code input library and battery temporary storage points during circulation and use, locking the circulation information.

[0055] S104, when the specified battery is sold, used and recycled, the identification information of the specified battery is added sequentially at the sales program node, the use program node and the recycling program node, generating the first supplementary information of the sales program node, the second supplementary information of the use program node and the third supplementary information of the recycling program node.

[0056] In the embodiments of this specification, the first supplementary information may include the sales amount, the seller's identifier, and the transaction time of the specified battery. The first supplementary information can be used to specify relevant information in the battery sales process, and the required information can be obtained subsequently through the first supplementary message. The second supplementary information may include the user's identifier and the usage time of the specified battery. The second supplementary information can be used to specify relevant information in the battery user's usage process, and the required information can be obtained subsequently through the second supplementary message.

[0057] In the embodiments of this specification, when generating the third supplementary information of the recycling program node, the shape of the specified battery can be recycled by the identification module. If it is determined that the shape of the specified battery meets the recycling detection requirements, the recycling direction of the specified battery is determined according to the identification information of the specified battery. Batteries whose shape meets the recycling detection requirements can be those that are undamaged or have only minor damage. If the battery is severely damaged and there is serious leakage of components, such batteries can be disposed of to avoid environmental impact.

[0058] In the embodiments of this specification, when the identification module performs recycling detection on the shape of the specified battery, the image of the specified battery can be determined first; the identification module analyzes the image of the specified battery to determine whether the shape of the specified battery meets the preset recycling requirements. The identification module can use a neural network.

[0059] In this embodiment of the specification, before determining the recycling direction of the designated battery based on its identification information, the designated battery can be subjected to component testing to determine its component information. The component information of the designated battery is then compared with a preset component standard to determine whether the designated battery has recycling value. If the designated battery is determined to have recycling value, the step of determining the recycling direction based on the identification information of the designated battery is executed. The recycling direction can be determined after analyzing the battery type. For example, the processing direction for lithium-ion batteries is to first incinerate the battery to remove organic matter, then screen to remove iron and copper, and finally heat and dissolve the remaining powder in acid. Cobalt oxide can then be extracted using an organic solvent and used as a raw material for pigments and coatings.

[0060] S106, store the first supplementary information, the second supplementary information and the third supplementary information in the previous level program node or the next level program node.

[0061] In the embodiments of this specification, storing the first supplementary information, the second supplementary information, and the third supplementary information in the upper-level program node or the lower-level program node can prevent the loss of information in a certain program node, thus preventing the situation where it cannot be queried.

[0062] S108, if it is determined that there is supplementary information for a missing program node in the sale, use and recycling of the specified battery, a traceability request is sent to the upper-level program node of the missing program node, so that the upper-level program node of the missing program node can call the supplementary information of the missing program node and supplement the identification information of the specified battery in the missing program node through the supplementary information of the missing program node.

[0063] In the embodiments described in this specification, a blockchain module can be used to verify the identities, lock in responsibilities, and ensure the security and immutability of data for the production program nodes, sales program nodes, user program nodes, and recycling program nodes, guaranteeing the authenticity and reliability of data during the recycling process of designated batteries. The blockchain module can provide functions such as digital identity management and authentication for organizations / individuals / devices, notarization of code generation and verification processes, notarization and auditing of authorization processes, and programmable smart contract capabilities. The blockchain service also supports cross-enterprise digital signature mutual trust and cross-enterprise device interconnection identity authentication.

[0064] It should be noted that the above process can be implemented through a battery recycling trading supply and demand module, establishing a trading platform for the recycling and reprocessing of waste batteries. This platform is divided into a sales outlet end and a recycler end, connecting the waste lead-acid battery recycling industry chain and addressing the pain points of sales outlets, recyclers, and smelters. The process is as follows: Repair shops collect batteries (with authorization) ---> Battery storage at designated storage points ---> Battery sorting ---> Shipping ---> Smelters receive waste batteries (fill out payment slips) ---> Payment is made, and the funds are then returned to each link in the distribution chain.

[0065] It should be noted that this specification discloses a waste lead-acid battery recycling management platform based on identifier resolution and blockchain. Based on the national identifier resolution system, each waste battery is assigned a unique identification code. The platform aggregates the identity information of various entities involved in the battery recycling process, providing a basic platform function for supply and demand matching. Each entity in the recycling process achieves traceability of battery recycling by scanning the updated identifier data when entering and leaving the warehouse. The smelter, the last link in the recycling chain, makes payments after recycling, and these payments are then returned to each entity to incentivize each link to maintain the identifier information as required. The innovation of this specification's embodiment differs from existing recycling models. It achieves traceability and legal recycling of waste batteries through identifier information, and uses blockchain to lock in the responsibilities of each entity at each stage. The platform achieves supply and demand matching for recycling, solving the difficult problems in the market's waste lead-acid battery recycling process.

The device includes: an identification generation unit 202, a supplementary information generation unit 204, a supplementary information storage unit 206, and an information traceability unit 208.

[0067] The identity generation unit 202 generates a corresponding identity number at the production process node when the specified battery is produced, and associates the identity number with the identification information of the specified battery.

[0068] The supplementary information generation unit 204, when the specified battery is sold, used, and recycled, sequentially supplements the identification information of the specified battery at the sales program node, the usage program node, and the recycling program node, generating the first supplementary information of the sales program node, the second supplementary information of the usage program node, and the third supplementary information of the recycling program node;

[0069] Supplementary information storage unit 206 stores the first supplementary information, the second supplementary information and the third supplementary information in the previous level program node or the next level program node;

[0070] If the information traceability unit 208 determines that there is supplementary information for a missing program node in the sale, use and recycling of the specified battery, it sends a traceability request to the upper-level program node of the missing program node so that the upper-level program node of the missing program node can call the supplementary information of the missing program node and supplement the identification information of the specified battery in the missing program node through the supplementary information of the missing program node.
