Description

Technical Field

[0001] This invention relates to the field of product traceability technology, specifically to a lock component, a locking device, a product sampling inspection method, and a product traceability management method. Background Technology

[0002] In recent years, with the continuous development of science and technology and the continuous improvement of people's living standards, the supply of daily necessities has become more complete and cheaper, greatly improving people's living experience. However, in actual life, the production and manufacturing of daily necessities has its normal costs, while some inferior daily necessities, due to their very low prices, are illegally used, thereby affecting the user experience or the user's health.

[0003] In existing technologies, businesses or stores often avoid providing substandard daily necessities to customers through self-regulation or passive supervision by relevant departments. However, the real-time performance and reliability of these supervision methods are poor, and therefore they cannot meet actual needs.

[0004] To address the aforementioned technical issues, existing businesses primarily rely on anti-counterfeiting labels to indicate whether a product is genuine. However, due to the diverse range of products available, many genuine products lack anti-counterfeiting labels, making this approach highly limited. In particular, for products like food, simply affixing anti-counterfeiting labels is insufficient. Unscrupulous individuals may remove these labels and attach them to inferior food products, or replace genuine products with anti-counterfeiting labels with counterfeit or substandard products for fraudulent sales. This significantly infringes upon users' rights, leads to the sale of substandard products, and poses potential safety threats. Summary of the Invention

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0031] In this invention, the terms "system" and "network" are used interchangeably. "Multiple" refers to two or more; therefore, in this invention, "multiple" can also be understood as "at least two." "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, it should be understood that in the description of this invention, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0032] Please see Figure 1 This invention provides a lock component, comprising: a lock body 20 including a locking part 201, the locking part including a lock shell 202, and a penetrating part 30. The locking part 201 and the penetrating part 30 cooperate to switch from an unlocked state to a locked state. The penetrating part 30 includes a first cavity 302, the side of which is at least partially surrounded by a transparent material. The first cavity 302 is filled / distributed with a fusible material 10 different from the transparent material, and the fusible material can be viewed through the transparent material.

[0033] In one possible implementation, on the one hand, to ensure that the user can view the characteristics of the fusible material 10 in the lock component at any time and verify its reliability; on the other hand, to facilitate the user's timely detection of any cut marks on the lock component, the side of the first cavity 302 is surrounded by a material that is at least partially transparent. For example, in the first embodiment, half of the side of the first cavity 302 is surrounded by a transparent material, and the other half is surrounded by an opaque material. In the second embodiment, the entire side of the first cavity 302 is surrounded by a transparent material for easy viewing by the user. Simultaneously, the fusible material 10 is placed in the first cavity 302. The fusible material 10 can be fully or partially filled into the first cavity 302, or it can be randomly distributed within the first cavity 302. In this embodiment, the transparent material softens above a set softening temperature. For example, the transparent material can include, but is not limited to, transparent resin, transparent plastic, glass, etc. The melting point of the fusible material 10 is not higher than the melting point of the transparent material, and the transparent material will interpenetrate and fuse with the fusible material 10 at the temperature corresponding to its melting point. The fusible material 10 is preferably a mixture of at least two materials that are fused together by heating, wherein at least one of the two materials has a color.

[0034] In this embodiment of the invention, a first locking tooth 203 can be provided in the locking part 201, and a corresponding second locking tooth 301 can be provided in the penetrating part 30. During use, by inserting the second locking tooth 301 of the penetrating part 30 into the lock shell 202 of the lock body 20, and allowing the second locking tooth 301 to enter the first locking tooth 203, the first locking tooth 203 and the second locking tooth 301 are engaged with each other. Thus, the second locking tooth 301 can move unidirectionally in the locking part 201. When the second locking tooth 301 moves to the point of locking the product, that is, when the lock component switches from the unlocked state to the locked state, the lock component can no longer move, thereby realizing the product locking function. In subsequent use, when the user receives the product locked by the locked component, the user can determine whether the lock component has been maliciously damaged or cut by observing whether the fusible material 10 in the lock component has changed, thereby ensuring the reliability of product traceability.

[0035] It should be noted that the above embodiment is only a specific embodiment of the present invention. The locking part 201 and the penetrating part 30 can also be locked in other ways, such as by bonding the top or side of the locking part 201 and the penetrating part 30 together to switch to the locked state; or, for example, corresponding insertion holes can be provided on the locking part 201 and the penetrating part 30. In this case, the locking part 201 and the penetrating part 30 can be moved in both directions to the position where the insertion holes are aligned, and then the locking part 201 and the penetrating part 30 can be switched to the locked state by the pin penetrating the insertion hole. Of course, other locking methods can be adopted according to actual needs, and no limitation is made here.

[0036] However, in practical applications, a malicious third party might consider cutting open both ends of the penetrating portion 30 and expelling the fusible material 10 to achieve a traceless cutting effect on the penetrating portion 30. Therefore, to solve the above technical problem, please refer to [link to relevant documentation]. Figure 2 In this embodiment of the invention, by providing a recessed structure and / or a raised structure 303 on the inner sidewall of the first cavity 302, the fusible material 10 is fixed and prevented from sliding within the first cavity 302, thereby effectively solving the aforementioned technical problem. It should be noted that there may be multiple recessed structures and / or raised structures 303, which can be arranged by those skilled in the art according to actual conditions; further details are omitted here.

[0037] In this embodiment of the invention, preferably, the fusible material 10 is a colored material, and the transparent material is colorless or its color is different from that of the fusible material 10. This arrangement effectively facilitates the user's distinction between the outer transparent material and the inner fusible material 10, thereby improving the user experience during the identification process.

[0038] More preferably, the fusible material 10 contains a first exotic impurity 11.

[0039] In this embodiment of the invention, by further dissolving the first exotic impurity 11 in the fusible material 10, on the one hand, the fusible material 10 has random characteristics, so that it can be detected in time even if it is replaced; on the other hand, it can make malicious cutting and destruction leave traces, thereby improving the reliability and security of the lock component.

[0040] To prevent third parties from damaging or cutting the lock components at lock housing 202, thus achieving low-cost or scratch-free disassembly, please refer to [link to relevant documentation]. Figure 3 A third cavity 204 may also be provided in the lock housing 202. A fusible material may also be filled / distributed in the third cavity 204. The fusible material in the third cavity 204 may be the aforementioned fusible material 10, or it may be a second fusible material different from the fusible material 10. The technicians may determine the material according to actual needs, and no limitation is made here.

[0041] It should be noted that the above-mentioned recessed structure and / or raised structure 303 can also be provided in the third cavity 204. This is a technical solution that is easy for those skilled in the art to conceive of based on the above invention, and will not be elaborated on here.

[0042] In this embodiment of the invention, the lock body 20 and the penetrating part 30 can be separately arranged or integrally formed.

[0043] Preferably, in an embodiment of the present invention, a second exotic impurity 40 is randomly distributed in the transparent material, that is, the second exotic impurity 40 is mixed and doped in the side portions of the lock body 20 and the penetrating portion 30.

[0044] More preferably, in order to improve the protection of the entire lock component, the lock component is made of a transparent material in which the second exotic impurity 40 is randomly distributed.

[0045] For example, please see Figure 4 In one embodiment, the aforementioned locking component can be configured on the packaging box to form a locking device. That is, the locking device provided in this embodiment is an integrated device of the locking component and the packaging box. Of course, it is easy to understand that the locking component and the packaging box can also be separate but configured as a set. The packaging box is one embodiment of the locking structure, and the locking structure can also be other structures, such as a restraint strap. In this case, the lock body 20 and the penetrating part 30 are separately arranged and are respectively fixed to the packaging box for use. In use, the packaging box can be a flip-top or open-top packaging box, which is not limited here. It should be noted that in this embodiment, when the locking component and the packaging box are separately arranged, at least one of the lock body 20 and the penetrating part 30 in the locking component is integrally arranged with the packaging box to ensure the integrity and reliability of the locking device.

[0046] After placing the product in the packaging box, the lid of the packaging box is closed, and the lock body 20 and the penetrating part 30 are locked. After locking, if a third party maliciously damages or disassembles the unlocking components, it will be necessary to cut and destroy the lock body 20 or the penetrating part 30. This will cause changes in the fusible material 10 in the penetrating part 30 or changes in the second exotic impurity 40 in the lock body 20. For example, during the use of laser cutting and ultrasonic welding, on the one hand, laser cutting will leave marks on the surface of the fusible material 10. On the other hand, in this embodiment of the invention, the melting point of the fusible material 10 is not higher than the melting point of the transparent material. At this time, the ultrasonic welding process will inevitably cause the fusible material 10 and the transparent material to fuse together, thereby damaging the lock components, so that the customer can promptly detect the damage to the lock components.

[0047] On the other hand, if a third party directly cracks or disassembles the packaging box, since the locking structure is made of a transparent material containing the second exotic impurity 40, the aforementioned malicious behavior will inevitably lead to a change in the characteristics of the second exotic impurity 40. Users can promptly detect changes in the packaging box and take corresponding rights protection measures, thereby effectively ensuring the reliability of the traceability operation.

[0048] In this embodiment of the invention, the locking device can be formed by injection molding or made by other processes, without further limitation.

[0049] For example, in practical applications, when an item needs to be kept in an irreplaceable or unalterable state (e.g., a preliminary step for traceability management), if the item has a physical shape, it can be placed in the packaging box of this locking device. Then, by fastening the lock body 20 and the penetrating part 30, the opening of the packaging box is secured by the first locking tooth 203 and the second locking tooth 301, thus locking the item inside the packaging box. Any attempt to replace the item would then require damaging the packaging box or the lock components. At this point, the user would inevitably notice the anomaly and assert their corresponding rights, effectively ensuring the item's resistance to substitution.

[0050] However, in practical applications, items that need to be locked may not be suitable for locking inside a box due to their size, quantity, or other reasons. For example, when locking livestock that need to be traced, it is impossible to lock them inside a packaging box for transportation and storage. In the fresh food and catering industry, for example, a lobster or scallop may be caught and sold individually and cannot be sealed in packaging. In order to meet the above requirements, this locking device can also adopt other configuration forms.

[0051] Please see Figure 5In one possible implementation, the lock body 20 and the penetrating part 30 are integrally formed during manufacturing to form a restraint strap. In practical applications, for example, when it is necessary to lock a pig, a hole can be drilled in the pig's ear, and the penetrating part 30 can be passed through the hole in the ear to lock the lock component, so that the locking device can be placed on the pig to be traced. Based on the above principle, any changes or replacements to the pig can be detected in time. In the second embodiment, when it is necessary to lock a chicken, the restraint strap can be put around the chicken's feet, and the lock component can be fastened to lock it on the chicken, thereby realizing the locking operation of the chicken.

[0052] Furthermore, it is readily apparent to those skilled in the art that, in order to achieve the tightening operation of the restraint strap, the bottom of the first locking tooth 203 can be in a through state. After the second locking tooth 301 is inserted into the first locking tooth 203, it can continue to move forward to reduce the restraint range of the restraint strap until the desired restraint range is met (for example, in this embodiment, it is reduced to the point where the chicken's foot is tightly restrained). Based on this, it is easy to understand that the length of the second locking tooth 301 on the penetrating part 20 needs to meet the above-mentioned restraint range requirements in order to achieve a reasonable restraint range effect, which will not be elaborated further here.

[0053] Furthermore, to meet the actual needs of more application scenarios, technicians can also configure corresponding storage bags for the restraint straps. For example, the restraint straps can be threaded through the opening of the storage bag, and after the product to be traced is placed into the storage bag, the restraint straps can be tightened to lock the product to be traced.

[0054] Of course, technicians can also apply the above-mentioned locking device to more scenarios according to actual needs, so as to meet the needs of more actual scenarios, which will not be elaborated on here.

[0055] In this embodiment of the invention, by designing the lock component in both through-hole and through-hole shapes, the practical application needs of most application scenarios in the product traceability protection process can be met, greatly improving the versatility of the locking device. At the same time, the unique features of the locking device can effectively ensure the reliability of the locked product, and when it is traced, it can ensure that its traceability information is reliable.

[0056] Preferably, a second exotic impurity 40, which is different from the fusible material 10, is randomly distributed in the above-mentioned transparent material. It should be noted that the exotic impurities mentioned in this invention may include, but are not limited to, foam, broken circuit boards, sand particles, etc., or dyes of different colors. No further restrictions are imposed here. The first exotic impurity, the second exotic impurity, and the third exotic impurity may indicate that they are exotic impurities with different serial numbers but the same, or they may indicate that they are exotic impurities of different kinds.

[0057] More preferably, the locking component is made of a transparent material in which the second exotic impurity 40 is randomly distributed. Specifically, the second exotic impurity 40 constitutes a unique feature of the locking device, so even if the locking device is deliberately damaged and replaced with another locking device, it can be detected in time, thereby achieving an effective anti-replacement effect.

[0058] In this embodiment of the invention, by designing the locking device as entirely or partially transparent, users can first check the packaging and locking components for signs of damage upon receiving the goods, and sign for them only after confirming there are no abnormalities, effectively avoiding disputes. Simultaneously, by randomly mixing a second exotic impurity 40 into the transparent material and using its characteristics as an anti-counterfeiting feature of the locking device provided by this invention, counterfeiting of the locking device can be effectively prevented, greatly improving the reliability, security, and anti-counterfeiting properties of the locking device, and meeting traceability requirements.

[0059] In this embodiment of the invention, the locking part 201 is embedded in the lock shell 202, and a second cavity 205 is formed between the locking part 201 and the lock shell 202.

[0060] In practical applications, since the locking device provided in this embodiment is made of transparent material, it may be artificially heated to a soft state and the lock component can be opened without damage, which will result in a loss of customer interests. Therefore, in order to improve the security of this locking device, in this embodiment of the invention, a fusible feature 50 is provided on the inner wall of the second cavity 205 near the locking part 201. The melting point of the fusible feature 50 is lower than the melting point of the lock shell 202 and the shape of the fusible feature 50 is randomly set.

[0061] In one possible implementation, the locking part 201 is a concave member with the first locking tooth 203 on its inner wall. The penetrating part 30 is fitted into the interior of the locking part 201 in the locked state. At this time, a second cavity 205 is formed between the locking part 201 and the lock shell 202. A fusible feature 50 is provided in the second cavity 205. For example, during the production of the lock component, the fusible feature 50 can be provided on the inner wall of the second cavity 205 of the lock component near the locking part 201 by injection or other means. The melting point of the fusible feature 50 is lower than the melting point of the lock shell 202, and the shape of the fusible feature 50 is randomly set as a special feature of the current lock component.

[0062] It should be noted that the fusible feature 50 can be directly injected and fused onto the inner wall of the second cavity 205 during the production of the lock component, or it can be fixed by setting a fixing structure inside the second cavity 205. The fixing structure can include, but is not limited to, hooks, support plates, clamps, etc. The fusible feature 50 can be injected onto the fixing structure to fix it and prevent it from falling off.

[0063] In practical applications, if someone maliciously heats the lock components, especially the first locking tooth 203 and the second locking tooth 301, in an attempt to soften the lock components for non-destructive disassembly, the fusible feature 50 located in the second cavity 205 will soften first, causing its shape to change, or even causing the fusible feature 50 to fall off. After receiving the locked item, the customer should first observe the integrity of the locking device, then verify the consistency of the second exotic impurity 40 in the locking device (to prevent the use of other legitimate locking devices to relock the item after the current locking device is damaged, even though all devices are legitimate, but replacement or alteration still occurs midway), and finally re-verify the shape and state of the fusible feature 50. This ensures that the locked item is not replaced or altered in any way, guaranteeing the reliability and traceability of the item.

[0064] It should be noted that, in the embodiments of the present invention, the first cavity 302 is set within a range that can include the locked item. For example, when the locking device described in the present invention is a strap-shaped locking device, the first cavity 302 extends from one end of the strap to the other end so that the locked item is included in the first cavity 302 in the locked state.

[0065] In this embodiment of the invention, by providing a first cavity 302 in the locking device, it is possible to effectively prevent the locking device from being seamlessly cut by tools such as lasers during use. Once such seamless cutting occurs, the inner wall of the first cavity 302 will have burrs or signs of damage, thereby further ensuring the reliability and traceability of the locking device.

[0066] Furthermore, in order to ensure that the seamless cutting operation of the locking device described in this invention by a third party can be reflected on the locking device and detected in a timely manner, multiple cavities can be provided. In the embodiment of this invention, the first cavity 302 is composed of multiple cavities, which are nested or independent of each other.

[0067] Furthermore, in this embodiment of the invention, to prevent the one-way locking part from being softened and then dragged for forced breaking, please refer to... Figure 6 A safety strip 206 can also be provided between the locking part 201 and the lock housing 202. The safety strip 206 is also made of transparent material, and the thickness of the safety strip 206 can be set to be less than the thickness of the first locking tooth 203 in the locking part 201. At this thickness, once the first locking tooth 203 is softened and stretched, the safety strip 206 will be stretched or even broken to achieve an irreversible effect, so that it can be detected by the user in time, thereby further improving the security and reliability of the locking device.

[0068] Furthermore, in this embodiment of the invention, since the penetrating part 30 is directly inserted into the locking part 201 of the lock body 20 during application, it is easy to see that, on the one hand, if a cavity is provided inside the penetrating part 30, a malicious third party can deform it by pinching the penetrating part 30, thereby achieving the effect of pulling it out of the locking part 201 without leaving a trace; on the other hand, after the penetrating part 30 is inserted into the locking part 201, since there is a gap between the part after the second locking tooth 301 and the lock shell 202, a malicious third party can also use a long strip of solid to forcibly insert it between the first locking tooth 203 and the second locking tooth 301 to separate it, thereby achieving the effect of pulling it out without leaving a trace. The above-mentioned malicious dismantling methods all cause financial losses to the user.

[0069] Therefore, in order to solve the above technical problems, please refer to Figure 7 By providing a semi-enclosed protective shell 304 outside the penetrating part 30 to protect the penetrating part 30, wherein the inner surface of the protective shell 304 is at least in contact with or wider than the outer surface of the lock shell 202, the penetrating part 30 can be effectively prevented from being squeezed and deformed or maliciously separated, thereby achieving a better protection effect.

[0070] In this embodiment of the invention, by setting the protective housing 304 as semi-enclosed, the protective housing 304 can pass through the outside of the locking part 201 to enable the second locking tooth 301 to pass through the first locking tooth 201 while protecting the second locking tooth 301, thereby effectively solving the above-mentioned technical problems and ensuring that the locking device has higher security and reliability.

[0071] On the other hand, embodiments of the present invention also provide a locking device, the locking device including the locking component described in the present invention, the locking component comprising a fusible material 10, and the locking device further including a locking structure made of a material doped with a third exotic impurity.

[0072] In this embodiment of the invention, by doping the locking structure with a third exotic impurity, the entire locking device has exotic features. After the product is locked by the locking device, malicious third parties cannot damage or replace the locking device by means of replacement, cutting, disassembly, etc., thereby effectively ensuring the locking effect of the locking device, improving the reliability of product traceability, and improving the reliability of product protection.

[0073] On the other hand, please see Figure 8 This invention provides a product sampling inspection method, the method comprising: S10) In response to product-customer binding information, obtain a sampling inspection flag, which is randomly generated; S20) If the sampling mark indicates sampling, obtain the product's locking status, which is determined by the locking device described in the embodiment of the present invention; S31) If the product is locked, obtain first recorded information for the locking device; S32) If the product is in an unlocked state, obtain second recording information for the product, the second recording information including recording information of the product from before responding to the product-customer information to when the locking device completes the locking process; S40) Perform a corresponding sampling operation based on the first recording information or the second recording information, wherein both the first recording information and the second recording information include the fusible material in the locking device and the locking device in a locked state.

[0074] In one possible implementation, to ensure the reliability and traceability of products during sales, use, and traceability protection, random sampling inspections are conducted on the products. Specifically, a pre-built sampling inspection system can be run. This system acquires the binding information between the monitored products and users in real time. For example, when a product is sold, reserved, or used, it may trigger the feedback of corresponding product-customer binding information to the sampling inspection system. This product-customer binding information may include, but is not limited to, customer order information for products, customer order information for dishes at restaurants, takeout order information, purchasing agent order information, seafood purchase information, hotel room check-in information, etc. After receiving the product-customer binding information, a sampling inspection mark is further obtained.

[0075] In this embodiment of the invention, in order to achieve complete randomization and unmanipulation of the sampling inspection behavior, the sampling inspection flag is randomly generated by a sampling inspection flag generator. The sampling inspection flag can be a data flag with a value of 0 or 1. When it is 0, it indicates that no sampling inspection operation is performed; when it is 1, it indicates that a sampling inspection operation is performed. The generation of the random flag is completely random and independent and is not affected by any external parameters.

[0076] After generating a sampling inspection mark, if the sampling inspection mark indicates sampling inspection, the product's locking status is immediately obtained. In this embodiment of the invention, the product's locking status is related to the locking device provided in this embodiment. For example, in the first embodiment, the product is pre-locked by the locking device, meaning the product is currently in a locked state. Then, first recording information for the locking device is obtained. This first recording information includes the fusible material 10 of the locking device and recording information of the locking device being in a locked state. This recording information includes, but is not limited to, recorded images, videos, etc. Specifically, when a product needs to be locked (e.g., when a product is packaged for resale, when a product purchased on behalf of another is purchased and packaged, or when seafood is caught and packaged), the merchant records first recording information for the entire process of the product being locked. In this embodiment of the invention, the locking method includes, but is not limited to, packaging, restraint, and ringing. It should be noted that the first or second recorded information should at least include the current product, the shape features of the locking device, and the features of the fusible material 10. It may also include features such as the pit structure and / or protrusion structure (303) (if any), the second exotic impurity 40 (if any), and the features of the fusible feature portion 50 (if any).

[0077] Subsequently, after obtaining the binding information between the product and the customer, the corresponding sampling inspection operation is performed based on the first recorded information mentioned above.

[0078] In the second embodiment, the product is not pre-locked by the locking device provided by the present invention, that is, the product is currently in an unbound state. Then, the second recording information for the product is immediately obtained. Specifically, after the product is configured to the user's consumption scenario, the consumption scenario can be continuously recorded through a fixed terminal device. After obtaining the product-customer binding information, the second recording information from before responding to the product-customer binding information to the completion of the locking process using the locking device is obtained, and the corresponding sampling operation is performed based on the second recording information.

[0079] Of course, the second recording information can also be recorded by personnel (staff or users) in the consumption scene after obtaining the inspection mark, starting from before the product is locked by the locking device through the terminal device. The recording process includes the process of the product being locked and information such as the shape and unusual features of the locking device that locks the product, and generates the corresponding second recording information, which will not be elaborated on here.

[0080] Specifically, after the product is locked by the locking device provided by this invention, a designated person takes the locked product to a designated inspection area for inspection. Before forcibly breaking the locking device and conducting the inspection, the inspector further collects pre-inspection images / videos of the locked product and uploads them to the traceability management platform before conducting the product inspection. When it is necessary to trace the reliability of its traceability information in the future, specifically when the user checks the reliability of the traceability information of similar products in the same batch as the product, the user compares and verifies the first or second recorded information and the corresponding pre-inspection images / videos to confirm that the current product and the locking device are not damaged or replaced before the inspection.

[0081] Of course, the traceability management system or inspection personnel can also immediately compare and determine whether the current product has been modified or replaced when they obtain the above information on-site, and only begin product inspection operations after confirming that the product is correct. Specifically, extract the first lock random feature corresponding to the locking device from the first or second recorded information; extract the second lock random feature corresponding to the locking device from the pre-inspection image / pre-inspection video; determine whether the first lock random feature and the second lock random feature are the same; if so, determine that the first or second recorded information matches the corresponding pre-inspection image / pre-inspection video; otherwise, determine that the first or second recorded information does not match the corresponding pre-inspection image / pre-inspection video.

[0082] During the inspection process, inspectors first need to forcefully break through the locking device, remove the locked product, and perform inspection operations on the product. After completing the sampling inspection, they obtain the sampling inspection results corresponding to the product and bind and store the sampling inspection results with the product's coding information to complete the product's sampling inspection verification process. The coding information includes, but is not limited to, the product's batch information.

[0083] In this embodiment of the invention, before any sale or use of the product, a random sampling inspection is triggered, and the product is locked by the locking device provided in this embodiment of the invention to ensure its authenticity when it is sampled during the sale or use process. This effectively constrains merchants to provide genuine and reliable products, eliminates counterfeiting and fraud, and protects the legitimate rights and interests of customers.

[0084] For further details, please see Figure 9 This invention provides a product traceability management method, applied to a traceability management system, the method comprising: S10) Obtain recording information for the product, the recording information including the fusible material 10 in the locking device according to the embodiment of the present invention, the product being locked by the locking device, and the recording information being recorded by the terminal device; S20) Obtain the product's coding information, and generate the product's traceability binding information based on the coding information and the recording information; S30) Perform the product sampling inspection method described in the embodiments of the present invention; S40) Determine whether a source tracing query instruction has been obtained; S50) If so, provide feedback on the traceability binding information corresponding to the current product.

[0085] In one possible implementation, a traceability management system is established to reliably manage product traceability. During product traceability management, traceability information is collected and managed from the product's source. Specifically, firstly, recorded information about the product is acquired. The product is locked by the locking device provided in this embodiment of the invention. This recorded information includes the fusible material 10 within the locking device, and the recorded information is recorded by a terminal device.

[0086] Specifically, in the first embodiment, when the traceability management system determines that a product needs to be traced, it sends a corresponding recording / shooting instruction to the terminal device, and the terminal device performs the corresponding recording operation based on the recording / shooting instruction; in the second embodiment, the recording information can also be recorded by the merchant inputting a corresponding operation instruction to the terminal device when the preset recording conditions are met. The preset recording conditions include, but are not limited to, at least one of the following: the recording location is in a preset location, the recording device is a trusted device, and the product to be recorded is the product at the time of recording.

[0087] During recording, the recording begins before the product is locked by the locking device provided by the present invention, and then the entire process of locking the product is recorded. After the product is locked, all features of the locking device (including but not limited to the shape, features of the fusible material 10, shape features of the fusible feature part 50, and locking status) are recorded to form corresponding traceability verification information.

[0088] In this embodiment, after the traceability management system receives the uploaded traceability verification information, it can further determine whether the random features of the locking device in the traceability verification information have been applied to other products. If they have been applied to other products, it can be considered that the locking device has been stolen or copied, and therefore it can be determined to be an illegal locking device.

[0089] In another embodiment, the user can also take a picture of the characteristic information of the locking device of a product through the user terminal and upload it to the traceability management system for verification. If the traceability management system determines that the characteristic information of the locking device is applied to other products or bound to other users, it can be considered that the locking device has been stolen or copied and pirated, and the locking device is identified as an illegal device and feedback is given to the user terminal.

[0090] For example, in one embodiment, the locking device consists of a lock component and a packaging box. During use, if the packaging box is maliciously opened, the lock component will show signs of damage. If the lock component is maliciously heated and an attempt is made to disassemble it without leaving a trace by softening the lock component, the fusible feature 50 will deform, thereby causing a change in the traceability verification information. After obtaining the packaging box with the lock component, the user can directly check the lock body 20 and compare the fusible feature 50 inside the current anti-substitution lock with the image / video at the time of packaging to determine whether the current locking device has been forcibly cracked.

[0091] For example, in the first embodiment, a hotel needs to manage the traceability of the purchased dishes. Therefore, when purchasing dishes, a handheld terminal device records the purchasing process, including selecting dishes, purchasing dishes, and receiving the receipt after purchase.

[0092] However, in practical applications, the traceability management system may receive recording information from various terminal devices. In order to ensure the reliability of the recording process, it is necessary to perform trusted verification on the terminal devices.

[0093] In this embodiment of the invention, the method further includes: obtaining authentication information of the terminal device; verifying the authentication information, and if the authentication information is verified successfully, determining that the terminal device is a trusted device; obtaining the location of the product's supply source and the geographical location of the terminal device; determining whether the terminal device is located within a preset range of the supply source location based on the geographical location; if the terminal device is a trusted device and the terminal device is located within the preset range of the supply source location, marking the recorded information as trusted and storing the recorded information.

[0094] In one possible implementation, the traceability management system simultaneously verifies multiple pieces of information about the terminal device. Specifically, it can first obtain the terminal device's authentication information. For example, it can pre-store the key seed of each legitimate terminal device in the traceability management system. This authentication information includes the terminal device's key seed. When the terminal device sends recording information to the traceability management system, the recording information can include the key seed to facilitate authentication. Of course, this authentication information can also be signature information formed by using a signature method based on a key and timestamp / interaction content as the original signature data. Of course, those skilled in the art, based on the above technical solution, can also generate the terminal device's authentication information in other ways. For example, a verification message can be pre-built into the terminal device or application. During interaction, the terminal device uploads the verification message and timestamp hash as a verification message hash value to the traceability management system for authentication. This authentication message includes, but is not limited to, the terminal device's ID, system version number (to determine if it is a customized system), device identification code (to determine if it is a customized device), and application identification code (to determine if its built-in application is a factory-installed application), etc., and verifies them. If the verification is successful, the terminal device is determined to be a trusted device.

[0095] On the other hand, the system can obtain the location of the supplier of the product to be traced and the current geographical location of the terminal device. This supplier location can be a location pre-entered by the merchant into the traceability management system, or it can be location information automatically retrieved by the system from a third-party information source based on supplier information. This geographical location includes, but is not limited to, the terminal device's current latitude and longitude, compass direction, pressure, and altitude. Based on this geographical location, it can be calculated whether the terminal device is currently within a preset range of the supplier location. If the terminal device simultaneously meets both of the above conditions—that is, the terminal device is a trusted device and its geographical location is within the preset range of the supplier location—then the recorded information is marked as trusted and stored.

[0096] For example, in one embodiment, merchants need to record traceability information for seafood products. Therefore, recording begins before setting sail. The recorded information includes, but is not limited to, information about the fish storage area and the coastline before fishing. Fishing begins upon reaching the fishing location (e.g., the seabed of a certain sea area). During the fishing process, fishing actions and environmental information are recorded in real time and then uploaded. In this embodiment, the terminal device can also collect GPS information and compass pointing information. When uploading the recorded information, it can also include the aforementioned GPS information and compass pointing information. Through the GPS information and compass pointing information, the traceability management system can obtain information about the merchant's geographical location changes and orientation during the fishing process, thereby accurately determining whether the recorded information was generated from fishing operations in the expected sea area. After landing, the recorded information also includes the process of tagging and entering information for the seafood products. For example, in this embodiment, the seafood products are locked using a restraint strap with locking components to complete the tagging operation. When recording traceability information, the specific characteristics of the seafood, the restraint strap, and the locking components need to be recorded and uploaded, and the batch information for each seafood product is also entered.

[0097] It should be noted that the above verification process can proactively request verification from the traceability management system before sending the recording instruction, and generate recording information after successful verification; alternatively, the terminal device can be verified after generating recording information from the traceability management system. If the verification is successful, the traceability management system stores the recording information; otherwise, the recording information is discarded or stored but not marked as trusted. Further details will not be elaborated here.

[0098] On the other hand, it is easy for those skilled in the art to understand that the verification process of the above two conditions should not include a specific order. The above embodiments are only preferred embodiments and are not intended to limit the execution order. Further details will not be provided here.

[0099] In this embodiment of the invention, by verifying the identity and recording location of the traceability information entered by the terminal device when acquiring the traceability information, the accuracy and reliability of the source of the traceability information can be effectively guaranteed, thus protecting the rights and interests of users.

[0100] During the generation of recorded information, the terminal device can directly upload the recorded information for a specific time period (the time period corresponding to the process of locking the product) to the traceability management system, or the terminal device can upload the recorded time frequency for the product in real time, and the traceability management system can automatically extract the recorded information for the corresponding time period.

[0101] In this embodiment of the invention, obtaining recording information for a product includes: obtaining a recorded video of the product, the recorded video including fusible material 10; determining a cut-off time period; performing video segment extraction on the recorded video based on the cut-off time period to obtain corresponding recording information, the recording information including the product's traceability information entry process or the binding process of the product's product information and customer information, the recording information being uploaded by a trusted device.

[0102] In one possible implementation, a recorded video of the product is first acquired. This recorded video includes the fusible material 10 in the locking device provided in this embodiment of the invention. Then, a cut-off time period is determined. For example, this cut-off time period can be manually specified by a technician, or it can be automatically determined by the traceability management system based on the identification results of the product to be recorded and the locking device locking it. Then, the recorded video is subjected to a corresponding video segment extraction operation according to the cut-off time period to obtain the corresponding recording information. The recording information includes the product's traceability information entry process or the binding process of the product's product information and customer information. In this embodiment of the invention, in order to ensure the reliability of the uploaded recorded video and the security of the recorded video after it is recorded, the terminal device uploading the recorded information is a trusted device, and this terminal device does not have any data interface. That is, the recorded information can only be uploaded to the traceability management system via wireless communication.

[0103] Since the traceability management system cannot verify the reliability of the recorded information, it cannot distinguish its authenticity. Since the images / videos may be forged or edited, reliability verification is required to improve the reliability of the recorded information.

[0104] Specifically, after obtaining the recording information, the continuity of the recording information can be verified. Specifically, during the recording process, the traceability management system can automatically generate a judgment on whether the recording frames of the recording information meet the preset continuous recording conditions. For example, if the recording information is a photo, it is necessary to verify whether the shooting time of each photo is less than the preset time interval. If the shooting time is less than the preset time interval, it is determined that the photo meets the preset continuous recording conditions. If the recording information is a video, the continuity of the video can be determined by verifying the continuity of the video frames (such as verifying whether there are transient frames). If the verification is successful, the above image information / video information is used for product identification to obtain the product identification number. This product identification number is configured for the product during the manufacturing process.

[0105] For example, in one embodiment, traceability management of hotel supplies is implemented. Specifically, when managing the traceability of bedding, after the bedding is produced or disinfected, a corresponding product identifier can be configured for the bedding. The product identifier includes, but is not limited to, character IDs containing its number, QR codes, multi-dimensional codes, RFID tags, etc., and can also be an identifier with specific shape characteristics. For example, in this embodiment, a sewn product made with a specific number of stitches, a specific sewing trajectory, or a specific sewing pattern is used as the product identifier for the bedding. In the process of using the sewn product as the product identifier for the bedding, the product identifier can be sewn onto its surface or sewn into the inside of the bedding. No further restrictions are imposed here.

[0106] After verifying the continuity of the recorded information, the product identifier in the recorded information can be identified using image recognition and other methods, and the product identification number can be identified. At this time, it is matched with the preset product number, which is the number that the merchant has pre-entered into the traceability management system.

[0107] In practical applications, although continuous verification is performed on the recorded information, it is still impossible to identify if the entire recorded information is falsified by the merchant. Therefore, in order to further ensure the reliability of the recorded traceability information, on-site verification information can be set up. The on-site verification information includes on-site verification information and verification time period. The on-site verification information can be preset by the management personnel and stored in a preset verification database. When a product enters traceability information, on-site verification information can be randomly generated based on the preset verification database, and the merchant is required to display the on-site verification information during the verification time period when recording traceability information to improve reliability.

[0108] In this embodiment of the invention, the method further includes: acquiring on-site verification information for the product, the on-site verification information including traceability verification content and traceability verification time period, the on-site verification information being randomly generated based on a traceability verification database; sending the on-site verification information to a terminal device; and acquiring and storing verification feedback information recorded by the terminal device in response to the on-site verification information.

[0109] Specifically, during the recording process, if the recorded information meets the preset continuous recording conditions, a verification frame corresponding to the traceability verification period is extracted from the recorded information. Then, feature recognition is performed on the verification frame to obtain verification features. At this point, it is determined whether the verification features match the traceability verification content. For example, in this embodiment, the traceability verification content includes, but is not limited to, information such as text, images, markings, and human actions displayed on-site. If the verification features match the traceability verification content, a verification result indicating that the continuous verification has passed is generated; otherwise, a verification result indicating that the continuous verification has failed is generated. If the recorded frame does not meet the preset continuous recording conditions, a verification result indicating that the continuous verification has failed is generated.

[0110] It should be noted that the above verification process can also be determined by the user. The traceability management system only needs to store the collected verification information on the server and display it to the user when needed, so that the user can verify the information himself, thereby reducing the computing pressure on the server. This will not be elaborated on further here.

[0111] In this embodiment of the invention, by adding random on-site verification information during the recording process of traceability information, and by verifying the recorded information on-site after obtaining it, the falsification of recorded information is effectively prevented, and the reliability of the recorded information is effectively guaranteed.

[0112] If the continuity verification of the recorded information passes, product identification is performed on the image / video information to obtain the corresponding product identification number. The product identification is configured during the product manufacturing process. It is then determined whether the product identification number matches the preset product number. If yes, a verification result indicating that the recorded information has passed is generated; otherwise, a verification result indicating that the recorded information has failed is generated.

[0113] Furthermore, if the product identification number is determined to match the preset product number, it is determined whether the product is locked by the locking device; if so, the lock association frame related to the locking device is extracted from the recorded information; the lock association frame is subjected to feature recognition to generate the corresponding lock feature; it is determined whether there is a matching feature in the preset feature library that matches the lock feature; if so, a verification result of random feature verification passing is generated; otherwise, a verification result of random feature verification failing is generated.

[0114] After obtaining the product's recording information, the system further obtains the product's encoding information and generates traceability binding information based on the encoding and recording information. This information is then stored in the traceability management system for later retrieval. In subsequent applications, the traceability management system monitors the product-customer binding information in real time. Upon obtaining this information, it first executes the product sampling method provided in this embodiment of the invention, and then determines whether a traceability query instruction has been received (e.g., sent by a user terminal). If so, it immediately provides the traceability binding information corresponding to the current product, allowing the user to view the product's traceability information.

[0115] For example, in one embodiment, a user asks a merchant to purchase products on their behalf overseas. After arriving at the purchasing location overseas, the merchant uses a trusted terminal device to start recording the purchasing process. After the product purchase is completed, the merchant uses the locking device provided in this embodiment to lock and package the product and its receipt. The terminal device records the entire process of purchasing and packaging the product, as well as the random and unique characteristics of the locking device. The recorded information is then uploaded to the traceability management system. For example, after uploading the recorded information to the traceability management system, the merchant further enters product-customer binding information, such as customer order information, room check-in information, and menu order information. At this time, the traceability management system monitors in real time whether it receives a traceability query command, for example, the traceability query command is issued by the user's terminal.

[0116] After receiving the packaging box containing their product, users first check the internal special substances through the transparent lock body to see if they are consistent. For example, they check whether the shape of the fusible feature 50 in the lock body 20 has changed, whether the position has changed, and whether the exotic substances mixed in the fusible feature 50 are consistent with those in the product packaging. At the same time, users also verify whether the second exotic impurity 40 mixed in the lock body 20 and the penetrating part 30 is consistent with those in the packaging. For example, users can obtain the traceability binding information of the product through the traceability interface (such as a QR code) set on the product packaging and perform consistency comparison to verify the product traceability and product reliability.

[0117] On the other hand, please see Figure 10 This invention provides a product traceability recording method, applied to a terminal device, wherein the terminal device is electrically connected to the traceability management system described in this invention, and the method includes: S10) In response to a recording request, perform a recording operation corresponding to the recording request and generate corresponding image information / video information, the image information / video information including the product preparation process, the product preparation process including the process of locking the product using the locking device according to the present invention; S20) Obtain product parameters and preparation scene information, and generate corresponding recording information based on the product parameters, the preparation scene information and the image / video information.

[0118] On the other hand, please see Figure 11 This invention provides a method for displaying traceability information, applied to a user terminal, wherein the user terminal is electrically connected to the traceability management system described in this invention, and the method includes: S10) In response to a user operation, send a source tracing information viewing instruction based on the user operation; S20) Obtain traceability binding information for the traceability information viewing instruction, wherein the traceability binding information is related to the locking device described in this invention; S30) Displays the traceability binding information.

[0119] In this embodiment of the invention, the traceability binding information includes recording information for the product, and displaying the traceability binding information includes: determining whether there is a trusted marker for the recording information; if the trusted marker exists, adding the trusted marker to the recording information, generating new traceability binding information, and displaying the new traceability binding information; otherwise, displaying the traceability binding information.

[0120] In one possible implementation, after purchasing a product, a user wishes to obtain and view the product's traceability information. Therefore, the user terminal is electrically connected to the traceability management system. For example, in this embodiment, the user terminal scans the QR code corresponding to the product to obtain an interface for connecting to the traceability management system, and establishes a connection based on this interface. The user then operates the user terminal, which monitors in real time whether it receives the user's operation. Upon receiving the operation, the user terminal sends a corresponding traceability information viewing command to the traceability management system. After receiving the traceability information viewing command, the traceability management system provides corresponding traceability binding information. Upon receiving this traceability binding information, the user terminal displays the traceability binding information.

[0121] Furthermore, the traceability binding information includes recorded information about the product. In order to improve the display effect of the traceability binding information, provide users with a better traceability viewing experience, and improve the accuracy of traceability, when displaying the traceability binding information, it is further determined whether the recorded information has a trusted tag. The trusted tag is generated in the verification process when the recorded information is stored. If a trusted tag exists, the trusted tag is added to and displayed for the recorded information.

[0122] In this embodiment of the invention, by providing users with a more prominent display method using trusted markings, users can more conveniently and intuitively see the traceability information and credibility of the current product, greatly improving the reliability of product traceability and enhancing the user experience.

[0123] Based on the same inventive concept, please refer to Figure 12This invention provides a product sampling inspection device, characterized in that the device includes: a flag acquisition unit, configured to acquire a sampling flag in response to product-customer binding information, the sampling flag being randomly generated; a status acquisition unit, configured to acquire the product's locking status when the sampling flag indicates sampling, the locking status being determined by the locking device described in this invention; a first recording unit, configured to acquire first recording information for the locking device when the product's locking status is locked, the first recording information including exotic impurities of the locking device and recording information of the locking device being in a locked state; a second recording unit, configured to acquire second recording information for the product when the product's locking status is unlocked, the second recording information including recording information of the product from before responding to the product-customer information to the completion of the locking process using the locking device; and a sampling inspection unit, configured to perform a corresponding sampling inspection operation based on the first recording information or the second recording information, both the first recording information and the second recording information including the fusible material 10 in the locking device and the locking device being in a locked state.

[0124] On the other hand, please see Figure 13 This invention provides a product traceability management device, applied to a traceability management system. The device includes: an information acquisition unit for acquiring recorded information about a product, the recorded information including fusible material 10 in a locking device as described in this invention, the product being locked by the locking device, and the recorded information being recorded by a terminal device; a traceability binding unit for acquiring product coding information and generating traceability binding information for the product based on the coding information and the recorded information; a sampling inspection unit for executing a product sampling inspection method as described in this invention; and a judgment unit for judging whether a traceability query instruction has been obtained, and if so, providing traceability binding information corresponding to the current product.
