[0002] In recent years, with the continuous development of science and technology, people's living standards have been continuously improved, and the supply of daily necessities has become more complete and cheaper, which has greatly improved people's life experience. However, in the actual life process, the production and manufacturing of daily necessities has its normal cost, and some inferior daily necessities are illegally used at very low prices, which in turn affects the user experience or affects the user's health.

[0003] In the prior art, each merchant or store often avoids providing inferior daily necessities to customers through self-regulation or passive supervision by relevant departments. However, the above-mentioned supervision methods have poor real-time performance and insufficient reliability, and therefore cannot meet actual needs.

[0004] In order to solve the above technical problems, existing merchants mainly use anti-counterfeiting marks to prompt users whether the products they are using are genuine products. However, due to the diversity of products in life, there are a large number of genuine products without anti-counterfeiting marks, so the limitations are very large. In particular, for products such as food, it is not possible to simply stick anti-counterfeiting marks to prevent counterfeiting. Illegal persons may tear off the anti-counterfeiting marks and stick them on inferior food, or replace genuine products with anti-counterfeiting marks with false and inferior products for false sales, thereby greatly infringing the rights and interests of users, leading to the sale of inferior products and causing potential security threats.

[0030] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0031] The terms "system" and "network" in the embodiments of the present invention can be used interchangeably. "Multiple" means two or more than two. In view of this, "multiple" can also be understood as "at least two" in the embodiments of the present invention. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the previous and subsequent associated objects are in an "or" relationship. In addition, it should be understood that in the description of the embodiments of the present invention, the words "first", "second", etc. are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0032] See also Figure 1 An embodiment of the present invention provides a lock component, which includes: a lock body 20, including a fixing portion 201, the fixing portion includes a lock shell 202, the lock component also includes a penetration portion 30, the fixing portion 201 and the penetration portion 30 cooperate with each other to switch from an unlocked state to a locked state; the penetration portion 30 includes a first cavity 302, the side surrounding material of the first cavity 302 is at least partially a transparent material, and 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 a possible implementation, on the one hand, in order to ensure that the user can check the characteristics of the fusible material 10 in the lock component at any time and verify the reliability; on the other hand, in order to facilitate the user to find the traces of the lock component being cut in time, the side surrounding material of the first cavity 302 is set to be at least partially transparent material. For example, in the first embodiment, half of the side of the first cavity 302 is surrounded by transparent material, and the other half is surrounded by opaque material; in the second embodiment, the side of the first cavity 302 is completely surrounded by transparent material for the convenience of user viewing, and the fusible material 10 is set in the first cavity 302 at the same time. The fusible material 10 can be fully filled or half filled into the first cavity 302, or can be randomly distributed in the first cavity 302. In the embodiment of the present invention, the transparent material is softened when it is above the set softening temperature. For example, the transparent material can include but is not limited to transparent resin, transparent plastic, glass and other materials. The melting point of the fusible material 10 is not higher than the melting point of the transparent material. The transparent material will interpenetrate and fuse with the fusible material 10 at the temperature corresponding to the melting point. The fusible material 10 is preferably a mixed material formed by heating at least two materials and fusing them together, and at least one of the two materials has a color.

[0034] In the embodiment of the present invention, a first latching tooth 203 may be provided in the fastening portion 201, and a second latching tooth 301 may be provided in the penetration portion 30. During use, the second latching tooth 301 of the penetration portion 30 is inserted into the lock shell 202 of the lock body 20, and the second latching tooth 301 enters the first latching tooth 203, so that the first latching tooth 203 and the second latching tooth 301 are engaged with each other, so that the second latching tooth 301 can move unidirectionally in the fastening portion 201. When the second latching tooth 301 moves to the extent of locking the product, that is, at this time, the lock component switches from the unlocked state to the locked state, and the lock component can no longer move, thereby realizing the locking function of the product. In the subsequent use process, when the user receives the product locked by the lock component, the user can determine whether the lock component is maliciously damaged or cut by observing whether the fusible material 10 in the lock component changes, 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, and the fixing portion 201 and the penetration portion 30 may also be locked in other ways, such as bonding the fixing portion 201 and the top or side of the penetration portion 30 together to switch to a locked state; for example, corresponding sockets may be provided on the fixing portion 201 and the penetration portion 30, and then the fixing portion 201 and the penetration portion 30 are bidirectionally moved to a position where the sockets are aligned, and then a pin is passed through the above sockets to switch the fixing portion 201 and the penetration portion 30 to a locked state. Of course, other locking methods may also be adopted according to actual needs, which are not limited here.

[0036] However, in actual application, a malicious third party may consider cutting the two ends of the penetration portion 30 and leading out the fusible material 10 to achieve the effect of cutting the penetration portion 30 without leaving any traces. Figure 2 In the embodiment of the present invention, a concave structure and / or a convex structure 303 is provided on the inner wall of the first cavity 302, so as to fix the fusible material 10 and prevent it from sliding in the first cavity 302, so as to effectively solve the above technical problems. It should be noted that there can be multiple concave structures and / or convex structures 303, and technicians can arrange them according to actual conditions, and no further details will be given here.

[0037] In the embodiment of the present 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. Through the above arrangement, it is possible to effectively facilitate users to distinguish the transparent material on the outside from the fusible material 10 inside, thereby improving the user experience during the identification process.

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

[0039] In the embodiment of the present invention, by further dissolving the first strange impurity 11 in the fusible material 10, on the one hand, the fusible material 10 has random characteristics, so that it can be discovered in time even if it is replaced. On the other hand, malicious cutting and destruction behaviors will not leave traces, thereby improving the reliability and safety of the lock component.

[0040] In order to prevent a third person from damaging or cutting the lock components from the lock housing 202, thereby achieving low-cost or traceless disassembly, please refer to Figure 3 A third cavity 204 may be provided in the lock housing 202, and a fusible material may be filled / distributed in the third cavity 204. The fusible material in the third cavity 204 may be the fusible material 10 mentioned above, or may be a second fusible material different from the fusible material 10. The technicians may determine this based on actual needs, and no limitation is made here.

[0041] It should be noted that the above-mentioned pit structure and / or protrusion structure 303 may also be provided in the third cavity 204, which is a technical solution that can be easily thought of by those skilled in the art based on the above-mentioned invention content, and will not be elaborated herein.

[0042] In the embodiment of the present invention, the lock body 20 and the penetration portion 30 may be separately provided or integrally formed.

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

[0044] Further preferably, in order to improve the protection effect of the entire lock component, the lock component is made of a transparent material with the second singular impurities 40 randomly distributed.

[0045] See for example Figure 4 In one embodiment, the lock component can be configured on the packaging box to form a locking device, that is, the locking device provided by the embodiment of the present invention is an integrated device of the lock component and the packaging box. Of course, it is easy to understand that the lock component and the packaging box can also be separated but configured as a set. The packaging box is an embodiment of the locking structure, and the locking structure can also be other structures, such as a restraining belt. At this time, the lock body 20 and the penetration portion 30 are separated from each other and are fixed on the packaging box for use. When 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 lock component and the packaging box are separated, at least one of the lock body 20 and the penetration portion 30 in the lock component is integrated with the packaging box to ensure the integrity and reliability of the locking device.

[0046] After placing the product in the packaging box, close the lid of the packaging box, and the lock body 20 and the penetration part 30 are in a locked state. After locking, if a third person maliciously damages or disassembles the unlocking part, the lock body 20 or the penetration part 30 needs to be cut and damaged, which will cause the fusible material 10 in the penetration part 30 to change or the second strange impurity 40 in the lock body 20 to change. For example, in the process of using laser cutting and ultrasonic welding, on the one hand, the laser cutting will leave marks on the surface of the fusible material 10, and on the other hand, in the embodiment of the present invention, the melting point of the fusible material 10 is not higher than the melting point of the transparent material. At this time, the fusible material 10 and the transparent material will inevitably fuse with each other during the ultrasonic welding process, thereby destroying the lock part, so that the customer can find the destruction and damage of the lock part in time.

[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 strange impurity 40, the above malicious behavior will inevitably lead to changes in the characteristics of the second strange impurity 40. Users can promptly discover changes in the packaging box and take corresponding rights protection measures in a timely manner, thereby effectively ensuring the reliability of the traceability operation.

[0048] In the embodiment of the present invention, the locking device may be formed by injection molding or by other processes, which will not be further limited herein.

[0049] For example, in actual application, when an item needs to be guaranteed to be in a state that cannot be replaced or changed (for example, a pre-step for traceability management), if the item is a physical item, it can be placed in the packaging box of the locking device, and then the lock body 20 and the penetration part 30 are buckled together, and the opening of the packaging box is buckled by the first latch 203 and the second latch 301, so as to achieve the effect of locking the item in the packaging box. At this time, any replacement operation of the item must be carried out by destroying the packaging box or the lock component, and at this time the user will inevitably find the abnormality and claim the corresponding protection rights, thereby effectively ensuring the anti-replacement effect of the item.

[0050] However, in actual application, the items that need to be locked may not be suitable for locking in the box due to reasons such as size, quantity, etc. For example, when locking livestock that need to be traced, they cannot be locked in the packaging box for transportation and storage. Another example is in the fresh food and catering field, for example, a lobster or scallop may be caught and sold separately, and cannot be sealed and packaged. In order to meet the above requirements, the locking device can also adopt other configurations.

[0051] See also Figure 5In a possible implementation manner, the lock body 20 and the penetration portion 30 are integrally formed during manufacturing and form a restraint belt. In actual application, for example, when a pig needs to be locked, a hole can be punched in the pig's ear, and the penetration portion 30 can be passed through the hole in the ear, and then the lock component can be locked to configure the locking device on the pig to be traced. Based on the above principle, any change or replacement operation on the pig can be discovered in time; in a second embodiment, when a chicken needs to be locked, the restraint belt can be put on the chicken's foot, and the lock component can be buckled to lock it on the chicken, thereby realizing the locking operation of the chicken.

[0052] Furthermore, it is easy for those skilled in the art to know that in order to achieve the tightening operation of the restraint belt, the bottom of the first tooth 203 can be in a through state, and the second tooth 301 can continue to move forward after being inserted into the first tooth 203 to narrow the restraining range of the restraint belt until the desired restraining range is met (for example, in the present embodiment, it is narrowed to tighten the chicken's feet). Based on this, it is easy to understand that the length of the second tooth 301 on the penetration portion 20 needs to meet the requirements of the above-mentioned restraining range in order to achieve a reasonable restraining range effect, and no further elaboration will be given here.

[0053] Furthermore, in order to meet the actual needs of more application scenarios, technicians can also configure corresponding storage bags for the restraints, such as passing the restraints through the opening of the storage bag, and after placing the product to be traced into the storage bag, tightening the restraints 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 to meet the needs of more actual scenarios, which will not be elaborated here.

[0055] In the embodiments of the present invention, by designing the lock component to be a shape without through holes and a shape with through holes, the actual application requirements of most application scenarios in the product traceability protection process can be met, and the versatility of the locking device is greatly improved. At the same time, the specific characteristics 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 traceability information.

[0056] Preferably, a second strange impurity 40 different from the fusible material 10 is randomly distributed in the above-mentioned transparent material. It should be noted that the strange impurities described in the present invention may include but are not limited to foam, broken circuit boards, sand and other substances, and may also be dyes of different colors. No excessive restrictions are made here. The above-mentioned first strange impurities, second strange impurities, and third strange impurities can indicate that they are the same strange impurities with different serial numbers, or they can indicate that they are different types of strange impurities.

[0057] Further preferably, the lock component is made of a transparent material randomly distributed with the second singular impurities 40. Specifically, the second singular impurities 40 constitute the singular feature of the locking device, so even if the locking device is artificially damaged and replaced with another locking device, it can be discovered in time, thereby achieving an effective anti-replacement effect.

[0058] In the embodiment of the present invention, by designing the locking device as a whole or partly transparent, it is convenient for users to first check whether there is any violent damage to the packaging box and the lock components when they obtain their products, and then sign for them after confirming that there is no abnormality, which can effectively avoid disputes. At the same time, by randomly mixing the second strange impurity 40 into the transparent material and using its characteristics as the anti-counterfeiting feature of the locking device provided by the present invention, it is possible to effectively prevent the imitation of the locking device, greatly improve the reliability, safety and anti-counterfeiting of the locking device, and meet the traceability requirements.

[0059] In the embodiment of the present invention, the fixing portion 201 is embedded in the lock housing 202 , and a second cavity 205 is formed between the fixing portion 201 and the lock housing 202 .

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

[0061] In a possible embodiment, the fixing portion 201 is a concave part with the first locking tooth 203 provided on the inner wall, and the penetrating portion 30 is embedded in the fixing portion 201 in the buckled state, and a second cavity 205 is formed between the fixing portion 201 and the lock shell 202. At this time, a fusible feature portion 50 is provided in the second cavity 205. For example, when producing the lock component, the fusible feature portion 50 can be provided on the inner wall of the second cavity 205 of the lock component near the fixing portion 201 by injection or the like. The melting point of the fusible feature portion 50 is lower than the melting point of the lock shell 202, and the shape of the fusible feature portion 50 is randomly set to serve as a specific feature of the current lock component.

[0062] It should be noted that the fusible feature 50 can be directly injected and melted on the inner wall of the second cavity 205 when producing the lock component, or a fixed structure can be set inside the second cavity 205. The fixed structure can include but is not limited to hooks, support plates, splints and other structures. The fusible feature 50 can be injected onto the fixed structure to fix it and prevent it from falling.

[0063] In actual application, once someone maliciously heats the lock component, especially the first latch tooth 203 and the second latch tooth 301, in the hope of softening the lock component for non-destructive disassembly, the fusible feature 50 arranged in the second cavity 205 will first soften, causing its appearance to change, and even the fusible feature 50 will fall off. After receiving the locked item, the customer first observes the integrity of the locking device, and then verifies the consistency of the second strange impurity 40 in the locking device (to prevent other legal locking devices from being used to re-lock after the current locking device is damaged. Although legal locking devices are used to lock the items, replacement or changes still occur in the middle), and finally verify the appearance and state of the fusible feature 50 again, so as to ensure that the locked item is not replaced or changed in any form, thereby ensuring the reliability and traceability of the item.

[0064] It should be noted that, in the embodiment of the present invention, the setting range of the first cavity 302 is a range within which the locked object can be included. For example, when the locking device described in the present invention is a locking device in the form of a restraining belt, the first cavity 302 extends from one end of the restraining belt to the other end so as to include the locked object in the first cavity 302 in the locked state.

[0065] In an embodiment of the present 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 a tool such as a laser during use. Once the above-mentioned seamless cutting occurs, burrs or signs of damage will appear on the inner wall of the first cavity 302, thereby further ensuring the reliability and traceability of the locking device.

[0066] Furthermore, in order to ensure that a third party's seamless cutting operation on the locking device described in the present invention can be reflected on the locking device and discovered in time, multiple cavities can be set. In an embodiment of the present invention, the first cavity 302 is composed of multiple cavities, and the multiple cavities are nested with each other or independent of each other.

[0067] Further, in the embodiment of the present invention, in order to prevent the one-way clamping portion from being softened and dragged for violent cracking, see Figure 6 A safety strip 206 may be provided between the fixing portion 201 and the lock housing 202. The safety strip 206 is also made of a transparent material, and the thickness of the safety strip 206 may be set to be smaller than the thickness of the first latch tooth 203 in the fixing portion 201. Under this thickness, once the first latch tooth 203 is softened and stretched, the safety strip 206 is elongated or even broken to achieve an irreversible effect, so that it can be discovered by the user in time, thereby further improving the safety and reliability of the locking device.

[0068] Furthermore, in the embodiment of the present invention, during the use of the penetration portion 30, since it is directly inserted into the fixing portion 201 of the lock body 20, it can be easily known that, on the one hand, if a cavity is set in the penetration portion 30, a malicious third party can deform the penetration portion 30 by pinching it, thereby achieving the effect of extracting it from the fixing portion 201 without leaving a trace; on the other hand, after the penetration portion 30 is inserted into the fixing portion 201, since there is a gap between the part after the second tooth 301 and the lock shell 202, the malicious third party can also use a long strip of solid to force it into between the first tooth 203 and the second tooth 301 to separate them, thereby achieving the effect of extracting it without leaving a trace. The above-mentioned malicious disassembly methods all cause loss of interests to users.

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

[0070] In the embodiment of the present invention, by setting the protective shell 304 to be semi-closed, the protective shell 304 can pass through the outer side of the fixing portion 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 safety and reliability.

[0071] On the other hand, an embodiment of the present invention further provides a locking device, which includes the locking component described in the present invention, the locking component contains a fusible material 10, and the locking device also includes a locking structure, which is made of a material doped with a third exotic impurity.

[0072] In the embodiment of the present invention, by doping the locking structure with a third strange impurity, the entire locking device has a strange feature. After the product is locked by the locking device, a malicious third party cannot non-destructively crack or replace the locking device by 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, see Figure 8 The embodiment of the present invention provides a product sampling inspection method, the method comprising: S10) Responding to the product-customer binding information, obtaining a random inspection mark, wherein the random inspection mark is randomly generated; S20) if the sampling inspection mark indicates sampling inspection, obtaining a locking state of the product, wherein the locking state is determined by the locking device according to the embodiment of the present invention; S31) if the locking state of the product is a locked state, obtaining first recording information for the locking device; S32) if the locking state of the product is unlocked, obtaining second recorded information for the product, the second recorded information including recorded information of the product from before responding to the product-customer information to completing the locking process using the locking device; S40) performing a corresponding sampling operation based on the first recording information or the second recording information, wherein the first recording information and the second recording information both include the fusible material in the locking device and the locking device in a locked state.

[0074] In one possible implementation, in order to ensure the reliability and traceability of products during sales, use and traceability protection, random sampling of products is performed. Specifically, a pre-built sampling system can be run, which obtains the binding information of the monitored products and users in real time. For example, when the product is sold, reserved or used, it may trigger the feedback of the corresponding product-customer binding information to the sampling system. The product-customer binding information may include but is not limited to the customer's order information for the product, the customer's order information for dishes in the restaurant, takeout order information, purchasing order information, seafood purchase information, hotel room check-in information and other information. After receiving the product-customer binding information, a sampling mark is further obtained.

[0075] In an embodiment of the present invention, in order to achieve complete randomization and non-manipulability of the sampling behavior, the sampling mark is randomly generated by a sampling mark generator. The sampling mark can be a data mark with a value of 0 or 1. When it is 0, it indicates that the sampling operation is not performed; when it is 1, it indicates that the sampling operation is performed. The generation of the random mark is completely random and independent, and is not affected by any external parameters.

[0076] After the random inspection mark is generated, if the random inspection mark indicates random inspection, the locking state of the product is immediately obtained. In the embodiment of the present invention, the locking state of the product is related to the locking device provided in the embodiment of the present invention. For example, in the first embodiment, the product is locked by the locking device in advance, that is, the product is currently in a locked state, then the first recording information for the locking device is obtained, and the first recording information includes the fusible material 10 of the locking device and the recording information of the locking device in the locked state. The recording information includes but is not limited to the recorded images, videos and other information. Specifically, when the product needs to be locked (for example, the product is packaged for sale, the purchased product is purchased and packaged, and the seafood is salvaged and packaged), the merchant records the first recording information for the entire process of the product being locked. In the embodiment of the present invention, the locking method includes but is not limited to packaging, binding, ringing and other methods. It should be noted that the first recorded information or the second recorded information should at least include the appearance features of the current product, the locking device, the features of the fusible material 10, and may also include the features of the pit structure and / or the protrusion structure (303) (if any), the second singular impurity 40 (if any) and the fusible feature part 50 (if any).

[0077] Thereafter, after the binding information between the product and the customer is obtained, a corresponding sampling operation is performed according to the first recording information.

[0078] In the second embodiment, the product has not been 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, and after the product-customer binding information is obtained, 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 according to the second recording information.

[0079] Of course, the second recording information can also be that a person (staff or user) in the consumption scene obtains the inspection mark and starts shooting the product through a terminal device before the product is locked by the locking device. The shooting process includes the process of the product being locked and the shape, singular features and other information of the locking device that locks the product, and the corresponding second recording information is generated, which will not be elaborated here.

[0080] Specifically, after the product is locked by the locking device provided by the present invention, special personnel will take the locked product to the designated inspection place for inspection. Before brute-forcing the locking device and conducting the inspection, the inspector will further collect recorded pre-inspection pictures / pre-inspection videos of the locked product, and upload them to the traceability management platform to conduct product inspection operations. 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 the same type of products in the corresponding batch of the product, the user will compare and verify the above-mentioned first recorded information or the second recorded information and the corresponding pre-inspection pictures / pre-inspection videos to confirm that the current product and the above-mentioned locking device are not damaged or replaced before the inspection.

[0081] Of course, the traceability management system or the inspector can also immediately compare and determine whether the current product has been modified or replaced when the above information is obtained on site, and start the product inspection operation after confirming that the product is correct. Specifically, extract the first lock random feature corresponding to the locking device from the first recording information or the second recording information; extract the second lock random feature corresponding to the locking device from the pre-inspection picture / pre-inspection video; determine whether the first lock random feature is the same as the second lock random feature; if so, determine that the first recording information or the second recording information matches the corresponding pre-inspection picture / pre-inspection video; otherwise, determine that the first recording information or the second recording information does not match the corresponding pre-inspection picture / pre-inspection video.

[0082] During the inspection process, the inspector first needs to brute force the above-mentioned locking device, take out the locked product and perform inspection operations on the product. After completing the sampling operation, obtain the sampling results corresponding to the product, and bind the sampling results with the coding information of the product for storage to complete the sampling verification process of the product. The coding information includes but is not limited to the batch information of the product and other information.

[0083] In the embodiment of the present invention, a random inspection operation is triggered on the product before any sale or use of the product, and the product is locked by the locking device provided by the embodiment of the present invention to ensure its authenticity when it is inspected during the sales or use process, thereby effectively constraining merchants to provide real and reliable products, eliminating counterfeiting and fraud, and protecting the legitimate rights and interests of customers.

[0084] For further information, see Fig. 9 The embodiment of the present invention provides a product traceability management method, which is applied to a traceability management system. The method includes: S10) obtaining recorded information for the product, wherein the recorded information includes the fusible material 10 in the locking device according to the embodiment of the present invention, the product is locked by the locking device, and the recorded information is recorded by the terminal device; S20) acquiring coding information of the product, and generating traceability binding information of the product based on the coding information and the recording information; S30) executing the product sampling method described in the embodiment of the present invention; S40) determining whether a traceability query instruction is obtained; S50) If yes, feedback the traceability binding information corresponding to the current product.

[0085] In a possible implementation, a traceability management system is built to reliably manage the traceability of products. In the process of tracing the traceability of products, the traceability information is collected and managed from the source of the product. Specifically, firstly, recorded information for the product is obtained. The product is locked by the locking device provided by the embodiment of the present invention. The recorded information includes the fusible material 10 in the locking device. The recorded information is recorded by the terminal device.

[0086] Specifically, in the first embodiment, when the traceability management system determines that a product needs to be traced, a corresponding recording / shooting instruction is issued 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 by inputting the corresponding operation instruction to the terminal device when it is determined that the preset recording conditions are met. The preset recording conditions include but are not limited to at least one of the conditions that the recording position is at a preset position, the recording device is a trusted device, and the product is a product to be recorded during recording.

[0087] When recording, the recording starts from before the product is locked by the locking device provided by the present invention, and then the entire process of the product being locked is recorded. After completing the locking operation of the product, all the features of the locking device (including but not limited to the outer shape, the features of the fusible material 10, the shape features of the fusible feature part 50, and the locking status, etc.) 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 applied to other products, it can be considered that the locking device has been stolen or copied and pirated, and can therefore be judged as an illegal locking device.

[0089] In another embodiment, the user may also use the user terminal to photograph the characteristic information of a locking device that locks a product 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, then it can be considered that the locking device has been stolen or copied and pirated, and the locking device is determined to be an illegal device and feedback is given to the user terminal.

[0090] For example, in one embodiment, the locking device is composed of a lock component and a packaging box. During use, if the packaging box is maliciously opened, the lock component may be seen to be damaged; if the lock component is maliciously heated and an attempt is made to soften the lock component and then disassemble it without leaving any trace, the fusible feature 50 will be deformed, thereby causing a change in the traceability verification information. After obtaining the packaging box equipped with the lock component, the user can directly view the lock body 20 and compare the fusible feature 50 in the current anti-replacement lock with the image / video at the time of packaging, thereby determining whether the current locking device has been brute-force cracked.

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

[0092] However, in actual application, the traceability management system may receive recording information from various terminal devices. In order to ensure the reliability of the recording process, the terminal devices need to be trusted and verified.

[0093] In an embodiment of the present invention, the method also includes: obtaining identity authentication information of the terminal device; verifying the identity authentication information, and if the identity authentication information is verified, determining that the terminal device is a trusted device; obtaining the supply source location of the product 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 a possible implementation, the traceability management system verifies multiple information of the terminal device at the same time. Specifically, the identity authentication information of the terminal device can be obtained first. For example, the secret key seed of each legal terminal device can be pre-stored in the traceability management system. The identity authentication information includes the secret key seed of the terminal device. When the terminal device sends the recording information to the traceability management system, the recording information can contain the secret key seed to facilitate the traceability management system to authenticate the identity. Of course, the identity information can also be a signature information formed by a signature method based on the key and the timestamp / interaction content as the signature original data. Of course, for those skilled in the art, according to the above technical solution, it can be thought that other methods can be used to generate the identity authentication information of the terminal device. For example, a verification information can be pre-built into the terminal device or application. When interacting, the terminal device hashes the verification information and the timestamp into the verification information hash value and uploads it to the traceability management system for identity authentication. The identity authentication message includes but is not limited to the ID of the terminal device, the system version number of the terminal device (to determine whether it is a customized system), the device identification code of the terminal device (to determine whether it is a customized device), the application identification code (to determine whether its built-in application is a factory application), and other information, and is verified. If the verification passes, the terminal device is determined to be a trusted device.

[0095] On the other hand, the supply source location of the product to be traced and the current geographical location of the terminal device can be obtained. The supply source location can be the location pre-entered by the merchant into the traceability management system, or it can be the location information automatically captured by the traceability management system from a third-party information source based on the supplier information. The geographical location includes but is not limited to the current latitude and longitude information of the terminal device, compass direction information, pressure information, altitude information and other information. According to the geographical location, it can be calculated to determine whether the terminal device is currently located within the preset range of the supply source location. If the terminal device meets the above two conditions at the same time, that is, the terminal device is a trusted device and the geographical location is within the preset range of the supply source location, the recorded information is marked as trusted and stored.

[0096] For example, in one embodiment, the merchant needs to record the traceability information of seafood products, so the recording starts before going out to sea. The recorded information includes but is not limited to the information of the fish warehouse and the coast before fishing, and the fishing begins after reaching the fishing location of the seafood (such as the seabed of a certain sea area). During the fishing process, the fishing action and fishing environment information are recorded in real time, and then the recorded information is uploaded. In an embodiment of the present invention, the terminal device can also collect GPS information and compass pointing information, etc. When uploading the recorded information, the recorded information can also include the above-mentioned GPS information and compass pointing information. Through the above-mentioned GPS information and compass pointing information, the traceability management system can obtain the merchant's geographical location change information and orientation information during the fishing process, so as to accurately determine whether the recorded information is generated by the fishing operation in the expected sea area. After landing, the recorded information also includes the process of labeling and information entry of seafood products. For example, in this embodiment, the seafood product is locked by a tie belt equipped with a lock component to complete the labeling operation. When recording the traceability information, the specific characteristics of the seafood, tie belt and lock component need to be recorded and uploaded, and the batch information of each seafood product needs to be entered at the same time.

[0097] It should be noted that the above-mentioned verification process can actively request verification from the traceability management system before sending the recording instruction, and the recording information will be generated after the verification is passed; it can also verify the terminal device after the recording information is sent to the traceability management system. If the verification is passed, the traceability management system will store the recording information, otherwise the recording information will be discarded or stored but not marked as trusted. No further details will be given 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 sequence. The above embodiment is only a preferred embodiment and is not regarded as a limitation on the execution order, so no further elaboration is made here.

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

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

[0101] In an embodiment of the present invention, the obtaining of recorded information for a product includes: obtaining a recorded video for the product, the recorded video including fusible material 10; determining a capture period; performing a video segment extraction operation on the recorded video based on the capture period to obtain corresponding recorded information, the recorded information including a process of entering traceability information of the product or a process of binding product information of the product with customer information, and the recorded information is uploaded by a trusted device.

[0102] In a possible implementation, firstly, a recorded video of the product is obtained, the recorded video includes the fusible material 10 in the locking device provided in the embodiment of the present invention, and then an interception period is determined. For example, the interception period can be manually specified by a technician, or the traceability management system can automatically determine the interception period based on the recognition results of the product to be recorded and the locking device that locks it. Then, the corresponding video segment extraction operation is performed on the recorded video according to the interception period to obtain the corresponding recording information, and the recording information includes the traceability information entry process of the product or the binding process of the product information and customer information of the product. In an embodiment of the present invention, in order to ensure the reliability of uploading the recorded video and the security of the recorded video after it is recorded, the terminal device that uploads the recorded information is a trusted device for uploading, and the terminal device does not have any data interface, that is, the recorded information can only be uploaded to the traceability management system through wireless communication.

[0103] Since the traceability management system cannot verify the reliability of the recorded information, it is impossible to distinguish its authenticity, and the pictures / videos may be forged or manually edited. Therefore, in order to improve the reliability of the recorded information, it is necessary to verify its reliability.

[0104] Specifically, after obtaining the recording information, the recording information can be verified for continuity. 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 photographed 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 (for example, verifying whether there are transient frames in the video frames, etc.), and if the verification is passed, the above-mentioned image information / video information is subjected to product identification recognition to obtain the product identification number of the product, which is configured for the product during the preparation process.

[0105] For example, in one embodiment, traceability management is performed on hotel supplies. Specifically, when traceability management is performed on bedding, a corresponding product identification can be configured for the bedding after it is produced or disinfected. The product identification includes but is not limited to a character ID containing its number, a QR code, a multi-dimensional code, an RFID tag, etc., and can also be an identifier with a specific shape feature. For example, in this embodiment, a sewn product made with a specific number of sewing stitches, a specific sewing trajectory, or a specific sewing pattern is used as the product identification of the bedding. In the process of using the sewn product as the product identification of the bedding, the product identification can be sewn on its surface or sewn inside the bedding, and no excessive restrictions are made here.

[0106] After confirming that the continuity verification of the recorded information has passed, image recognition or other methods can be used to identify the product logo in the recorded information and identify the product identification number therein. At this time, it is matched with the preset product number, which is the number pre-entered into the traceability management system by the merchant.

[0107] In actual application, although the recorded information is continuously verified, if the entire recorded information is falsely recorded by the merchant, it is still impossible to identify it. Therefore, in order to further ensure the reliability of the recorded traceability information, on-site verification information can also be set. The on-site verification information includes on-site verification information and verification period. The on-site verification information can be pre-set by the management personnel and saved in a preset verification library. When the traceability information of a product is entered, the on-site verification information can be randomly generated based on the preset verification library, and the merchant is required to display the on-site verification information during the verification period when recording the traceability information to improve reliability.

[0108] In an embodiment of the present invention, the method also includes: obtaining on-site verification information for the product, the on-site verification information including traceability verification content and traceability verification period, and the on-site verification information is randomly generated based on a traceability verification library; sending the on-site verification information to a terminal device; obtaining and storing verification feedback information recorded by the terminal device for the on-site verification information.

[0109] Specifically, during the recording process, when it is determined that the recording information meets the preset continuous recording conditions, the verification frame corresponding to the traceability verification period is extracted from the recording information, and then the verification frame is feature-recognized to obtain the verification feature. At this time, it is determined whether the verification feature matches the traceability verification content. For example, in this embodiment, the traceability verification content includes but is not limited to text, pictures, marks, human body movements and other information displayed on site. If the verification feature matches the traceability verification content, a verification result of continuity verification passing is generated; otherwise, a verification result of continuity verification failing is generated; if the recording frame does not meet the preset continuous recording conditions, a verification result of continuity verification failing is generated.

[0110] It should be noted that the above verification process can also be judged by the user independently. The traceability management system only needs to store the collected verification information in the server and display it to the user when needed. The user can verify the information by himself to reduce the computing pressure of the server. I will not go into details here.

[0111] In the embodiment of the present invention, random on-site verification information is added during the recording process of the traceability information, and on-site verification is performed after the recorded information is obtained, thereby effectively preventing the falsification of the recorded information and effectively ensuring the reliability of the recorded information.

[0112] When the continuity verification of the recorded information passes, the image information / video information is subjected to product identification recognition to obtain the corresponding product identification number, and the product identification is configured during the product preparation process; it is determined whether the product identification number matches the preset product number; if so, a verification result indicating that the recorded information verification passes is generated; otherwise, a verification result indicating that the recorded information verification fails is generated.

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

[0114] After obtaining the recorded information of the product, the coding information of the product is further obtained, and the traceability binding information of the product is generated according to the coding information and the recorded information, and the information is stored in the traceability management system and waits for calling. In the subsequent application process, the traceability management system monitors the product-customer binding information in real time, and after obtaining the product-customer binding information, first executes the product sampling method provided by the embodiment of the present invention, and then determines whether a traceability query instruction is obtained. For example, the traceability query instruction can be sent by the user terminal. If so, the traceability binding information corresponding to the current product is immediately fed back for the user to check the traceability information of the current product.

[0115] For example, in one embodiment, a user asks a merchant to purchase a product on his behalf overseas. After the merchant arrives at the purchasing site overseas, he uses a trusted terminal device to start recording the purchasing process of the product. After the product is purchased, the locking device provided in the embodiment of the present invention is used to lock and package the product and the product receipt. The terminal device records the entire process of product purchase and packaging, as well as the random specific characteristics of the locking device, and then uploads the recorded information to the traceability management system. For example, after the merchant uploads the recorded information to the traceability management system, the merchant further enters product-customer binding information, such as customer order information, room occupancy information, and food order information. At this time, the traceability management system monitors in real time whether a traceability query instruction is obtained, for example, the traceability query instruction is issued by a user terminal held by the user.

[0116] After receiving the packaging box containing his product, the user first checks through the transparent lock body to see whether the specific substances inside are consistent, for example, whether the shape of the fusible feature part 50 in the lock body 20 is deformed, whether the position is changed, and whether the strange substances mixed in the fusible feature part 50 are consistent with those when the product is packaged. At the same time, the user also verifies whether the second strange impurities 40 mixed in the lock body 20 and the penetration part 30 are consistent with those when packaged. For example, the user obtains the traceability binding information of the product through the traceability interface (such as a QR code) set on the product packaging, and performs a consistency comparison to perform product traceability and product reliability verification.

[0117] On the other hand, see Fig.10 The embodiment of the present invention provides a product traceability recording method, which is applied to a terminal device, and the terminal device is electrically connected to the traceability management system according to the embodiment of the present invention. The method includes: S10) in response to a recording request, performing a recording operation corresponding to the recording request and generating corresponding picture information / video information, wherein the picture information / video information includes a product preparation process, wherein the product preparation process includes a process of locking the product using the locking device according to the present invention; S20) Acquire product parameters and preparation scene information, and generate corresponding recording information based on the product parameters, the preparation scene information and the picture information / video information.

[0118] On the other hand, see Fig.11 The embodiment of the present invention provides a traceability information display method, which is applied to a user terminal, and the user terminal is electrically connected to the traceability management system according to the embodiment of the present invention. The method includes: S10) in response to a user operation, sending a traceability information viewing instruction based on the user operation; S20) obtaining traceability binding information for the traceability information viewing instruction, wherein the traceability binding information is related to the locking device of the present invention; S30) Displaying the traceability binding information.

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

[0120] In a possible implementation, after purchasing a product, the user wishes to obtain and view the traceability information of the product, and therefore electrically connects the user terminal to the traceability management system. For example, in this embodiment, the user terminal obtains an interface connected to the traceability management system by scanning the QR code corresponding to the product, and establishes a connection relationship with the traceability management system based on the interface. Then the user operates the user terminal, and the user terminal monitors in real time whether the user operation is obtained, and when the user operation is obtained, the corresponding traceability information viewing instruction is sent to the traceability management system. After obtaining the traceability information viewing instruction, the traceability management system feeds back the corresponding traceability binding information, and the user terminal displays the traceability binding information after receiving the traceability binding information.

[0121] Furthermore, the traceability binding information includes recorded information for 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 traceability accuracy, when displaying the traceability binding information, it is further determined whether there is a trusted mark for the recorded information.
