Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Specific implementations of the invention are described in detail below in connection with specific embodiments.
The product quality traceability system and method based on the Internet of things provided by the invention solve the technical problems in the background technology.
As shown in fig. 1, a main flow chart of a product quality tracing method based on the internet of things provided by an embodiment of the present invention includes:
step S10: acquiring a circulation identification code of a first product according to the product split charging traceability request information; for a product split charging traceability request, whether the product is distributed and disassembled or not is reflected on a circulation identification code, and a basic identification subcode of the circulation identification code comprises necessary information such as the type, the model and the like of the product; the first product is one of the products, a plurality of the products are firstly packaged in sub-packaging parts, and a plurality of the sub-packaging parts are packaged in the sub-packaging parts;
step S11: acquiring an added character of the circulation identification code; particularly, whether the product is distributed and circulated or not is reflected on an added character of the added character bit of the circulation identification code;
step S12: reading the distribution disassembly and assembly information of the sub-package according to the added character and the product transaction authentication information, the distribution disassembly and assembly information comprises a first product first distribution disassembly and assembly information of the sub-split-assembly, the sub-split-packaging parts comprise a plurality of sub-split-packaging parts; if, on the other hand, the increment character of the increment character bit is empty, indicating that the first product has not been distributed, the first product is indicated to be always in the original sub-split-package, and the sub-split-package is in the fixed position of the split-package;
the arrangement of characters and product transaction authentication information is added, which indicates that the two conditions are required to be met when the distribution disassembly and assembly information is read, so that the non-regular acquisition channel of the distribution disassembly and assembly information can be effectively reduced, and the operation amount of data is reduced;
the distribution disassembly information generally relates to part process records or whole process records of distribution disassembly, and when a product relates to the movement in and out of sub-split parts, involves the transfer of a product between sub-packages, which may involve the transfer between packages when a product is not involved in the transfer of a sub-package into or out of a sub-package; the two processes can be recorded, for example, the moving-in and moving-out processes are recorded, the transfer of the sub-package is recorded, the read content comprises the number and model number of products, the moving-in, moving-out or moving-out time, moving specific operation images and the like, and the recorded information can be recorded in the sub-package or uploaded to a server after being recorded, so that the information is used as the distribution and disassembly information of the sub-package;
step S13: judging whether the first product has scattered transfer sub-packaging attributes according to the first distribution disassembly and assembly information, wherein the scattered transfer sub-packaging attributes are used for representing that a certain product is transferred between sub-packaging pieces; considering the distribution demand, the number of products required by each dealer or demander may be unequal, but in practice, the products, sub-packages, packages conform to a fixed loading and quantity relationship, thus most likely involving the sporadic transfer of the first product, i.e., the transfer of the first product from one sub-package to another to meet the actual quantity demand; it should be noted that, when the entire transfer between the sub-packages is involved, the difficulty of replacing the whole sub-split-package piece is high, so that the important consideration is that a certain product is transferred between the sub-split-package pieces;
step S14: if the first product has scattered transfer sub-packaging attributes, detecting whether an actual transfer path corresponding to the first product accords with a theoretical transfer path of the first product between the first sub-packaging piece and the second sub-packaging piece; when the first product has scattered transfer and split charging attributes, the result is directly reflected in the distribution disassembly and assembly information, so that the correlation detection of coincidence between the actual transfer path and the theoretical transfer path can be realized by identifying the result during split charging transfer, and the result can be directly read at the moment or directly identified based on the first distribution disassembly and assembly information;
whether the actual transfer path corresponds to a theoretical transfer path of the first product between the first sub-package and the second sub-package indicates whether the transfer process of the first product between the first sub-package and the second sub-package corresponds to a virtual theoretical transfer process, for example, the transfer of the first product between corresponding identical positions between the first sub-package and the second sub-package, and the relative positions between the first sub-package and the second sub-package are determined, wherein the transfer path of the first product between the first sub-package and the second sub-package is predictable, such as an arc-shaped section with the relative positions as a starting point and an ending point, respectively; if the first product is maliciously replaced in the transferring process, obviously, the identified actual transferring path may have abnormality, for example, an unnecessary road section exists, so that the path is overlong, etc. (the first product is convenient to replace);
step S15: if the product is matched with the first product, judging that the product split charging of the first product is qualified after tracing. And the product split charging is qualified after tracing, namely the transfer process of the first product between the first sub-split charging piece and the second sub-split charging piece is qualified, and no intentional or unintentional replacement exists.
When the method is applied, in consideration of split charging and specific requirement conditions of products, the added characters of the circulation identification codes are set, the added characters can carry out preliminary circulation tracing, in consideration of abnormal acquisition channels of split charging and disassembling information, the split charging and disassembling information of split charging pieces is read through the added characters and the product transaction authentication information, whether the first products have the split charging attribute is judged according to the first split charging and disassembling information, and if the first products have the split charging attribute, whether actual transfer paths corresponding to the first products accord with theoretical transfer paths of the first products between the first sub-split charging pieces and the second sub-split charging pieces is detected; if yes, judging that the product split charging of the first product is qualified, further circulation tracing is achieved, conditional at least two-stage circulation tracing is achieved integrally, and whether the first product is replaced in the transfer process between the first sub split charging piece and the second sub split charging piece can be identified.
As shown in fig. 2, as a preferred embodiment of the present invention, before the circulation identification code of the first product is obtained according to the product split charging traceability request information, the method further includes:
step S20: acquiring a tracing code verification result of the first product; the tracing code verification result generally verifies the individual tracing codes of the first product or the tracing codes of sub-split-package parts of the first product; the method mainly comprises the steps of verifying the production process, the production date and the like, wherein the step is common traceability verification in the prior art; the types of products in the present application are not limited as long as they can be used for packaging, for example, agricultural products, industrial products, living goods, and the like;
step S21: when the tracing code verification result shows that the tracing code verification result is qualified, receiving qualified identity information of an operator and continuous authentication operation input information; qualified identity information of an operator generally comprises face recognition information, account verification information and the like, and the operator is generally limited to buyers; continuing to authenticate the operation input information including operation confirmation of the traceability request;
step S22: and generating product split charging traceability request information of the first product according to the qualified identity information of the operator and the continuous authentication operation input information. When the conditions of qualified identity information of an operator and continuous authentication operation input information are met, if the login account number and the operation confirmation are the same, product split charging traceability request information is generated, namely if any of the conditions is not met, the fact that the product split charging traceability is not passed is indicated, and the product split charging traceability request is meaningless.
It can be understood that the product split charging traceability request information of the first product is generated according to the qualified identity information of the operator and the continuous authentication operation input information, so that traceability caused by invalid product split charging traceability request information is reduced, and the reasonable and effective product split charging traceability request is ensured.
As shown in fig. 3, as a preferred embodiment of the present invention, the obtaining the augmentation character of the stream identifier includes:
step S111: comparing the circulation identification code with the standard circulation identification code to obtain an added character of the circulation identification code, wherein the added character is generated according to the circulation split charging process of the product, the product comprises a first product, and obviously if the added character of the circulation identification code is not read, the added character of the circulation identification code is a vacancy, the sub split charging piece where the first product is located is indicated to be not distributed and disassembled, otherwise, the sub split charging piece where the first product is located is distributed and disassembled, and specifically, generating the added character according to the circulation split charging process of the product comprises:
step S112: the disassembly and assembly opening certificate of the split charging piece is obtained, sub-split charging of product according to disassembly and assembly opening certificate movement information of the parts relative to the first sub-set limit position, the movement information comprises movement time and movement distance, wherein a plurality of first sub-packaging limiting positions are arranged in the sub-packaging parts; the disassembly and assembly opening certificate comprises disassembly and assembly opening instructions, qualified identity information of disassembly and assembly opening, it is desirable to include at least one of the sub-assemblies being movable relative to the first sub-assembly by a limited amount, it is possible that the sub-packages move within the package, the former involving the transfer of the first product, and the latter involving the overall transfer of the sub-packages, or that the sub-packages move between packages; illustratively, the travel time is 2023/0610/1320, the travel distance is expressed as an internal travel 12I, I is an inside, i.e., 12 represents 12 units of travel; the non-internal part is not provided with an I mark; the disassembly and assembly opening certificate is qualified identity code XXXY;
step S113: and generating an added character of the circulation identification code according to the disassembly and assembly opening certificate and the movement information. Therefore, the added character of the circulation identification code is XXXY-0610/1320-12I, and certainly, the disassembly and assembly starting certificate and the movement information can be converted into the added character of the circulation identification code after the character conversion;
it should be understood that by combining the disassembly and assembly starting certificate and the movement information, a record of whether disassembly and assembly are qualified or not and movement is formed, whether the first product is circulated or not can be directly read through the circulation identification code by adding characters of the Cheng Liuzhuai identification code, and detailed and reliable records are corresponding to the specific circulation situation, so that the tracing is convenient.
As a preferred embodiment of the present invention, reading the distribution disassembly and assembly information of the sub-package according to the augmentation character and the product transaction authentication information includes:
step S121: and acquiring transaction authentication information of both sides of the product, and reporting the transaction authentication information of both sides and the added character to acquire a decryption file obtained by decrypting the distribution disassembly and assembly information. The transaction authentication information of the two parties comprises qualified authentication identities, qualified authentication programs and the like of the two transaction parties of the product;
the first example is that the client side encrypts the transaction authentication information of both sides and the added character through a public key and reports the encrypted transaction authentication information and the added character to the server, the server decrypts the received data by using a private key, verifies the reliability of the transaction authentication information of both sides and the added character (including verifying whether the transaction authentication condition is met or not and the authenticity of the added character), and supports the client side to log in or supports the node to log in about the distribution disassembly information when the verification passes so as to acquire the distribution disassembly information, so that illegal acquisition of the distribution disassembly information after the transaction authentication information of both sides and the added character are revealed can be avoided; the public key and the private key are a key pair obtained through a non-encryption algorithm, the public key is used for encryption, and the data encrypted by the public key can be decrypted only by using the corresponding private key;
in the second example, when the distribution disassembly and assembly information is stored locally, the distribution disassembly and assembly information is encrypted, and the server issues a decryption file for decrypting the distribution disassembly and assembly information by reporting the transaction authentication information of both parties and the added character to the server, so as to realize local decryption. The first and second examples may be implemented in combination or may be implemented separately.
When the method is applied, the first distribution disassembly and assembly information can be obtained through the transaction authentication information and the added characters of the two parties, so that the difficulty of obtaining the first distribution disassembly and assembly information can be increased, abnormal obtaining channels can be reduced, and the operation amount of data can be reduced.
As shown in fig. 4, as a preferred embodiment of the present invention, the method further includes:
step S30: when the first sub-assembly and the second sub-assembly are in a set horizontal alignment, prompting the first product to be packaged in the first sub-package and the second sub-split components are transferred in parallel; the parallel transfer is in accordance with a set horizontal alignment state when the transfer is performed; setting a horizontal alignment state for simplifying the transfer path;
step S31: acquiring an actual transfer path of the first product for parallel transfer;
specifically, after detecting that the first sub-split-package piece and the second sub-split-package piece are in a set horizontal alignment state, periodically collecting the positions of products to be detected, and spatially arranging the positions of the products to be detected according to time sequence, so that an actual transfer path can be obtained; for example, by periodically capturing an image of a product to be detected, identifying the position of the product in the image, and then distributing the position of the product in the image in the same plane, an actual transfer path can be obtained; it should be noted that the acquisition of the position of the product to be detected can be performed by the characteristics of the product to be detected, if the position which does not accord with the characteristics of the first product is obviously acquired, the position should be acquired and marked, and the subsequent position can be directly used for judging whether the first product is replaced or not; the features of the first product comprise feature shapes or identifiers of the first product, and the identifiers comprise tracing codes of the product;
step S32: detecting whether the actual transfer path is similar to the theoretical transfer path, wherein the theoretical transfer path is the theoretical transfer path of the first product relative to the first sub-split charging piece and the second sub-split charging piece; the theoretical transfer path is based on the first sub-set of the set horizontal alignment state Split charging member and second sub-split charging member is calculated by simulation of the corresponding position of the sensor; the theoretical transfer path, for example, defining the transfer of the first product at the same corresponding positions of the first sub-package and the second sub-package, respectively, is generally used to simulate the transfer path of the first product, including an arc or similar arc formed between the same corresponding positions, such as a downwardly opening parabola, and the criteria for detecting whether the actual transfer path is similar to the theoretical transfer path include: the path length difference, the similarity of the path shape and the dense distribution of the positions of the products, and if one of the two paths is unsatisfied, the dissimilarity between the actual transfer path and the theoretical transfer path is judged, namely, the travel for transferring or replacing the first product exists; for the dense distribution of the positions of the products, if the density of the positions of the products is too high, the abnormal stay is indicated; also determining dissimilarity between the actual transfer path and the theoretical transfer path;
step S33: if so, the first and second data are not identical, it is determined that the actual transfer path corresponds to the theoretical transfer path of the first product between the first sub-assembly and the second sub-assembly.
It will be appreciated that the determination of the actual transfer path corresponds to the theoretical transfer path of the first product between the first sub-package and the second sub-package, i.e. is mainly used to verify that the transfer of the first product between the first sub-package and the second sub-package is a continuous and normal process, and is not continuous (when there is a replaced moment) nor too far from the travel (when there is a replaced travel), so that the detection method provided by the embodiment can improve the probability of identifying that the first product is replaced in consideration of various possibilities.
As shown in fig. 5, as a preferred embodiment of the present invention, the method further includes:
step S40: based on the second sub-split-packaging limiting position corresponding to the sub-split-packaging piece, reading the identification information of the first sub-split-packaging piece and the second sub-split-packaging piece to detect whether the first sub-split-packaging piece and the second sub-split-packaging piece are positioned on the second sub-split-packaging limiting position corresponding to the split-packaging piece; specifically, in the implementation process, two second division limiting positions are respectively provided with an identification information reading device or a module; the identification information comprises an (electronic) identification code, which can be a package tracing code or a different identification code;
step S41: if so, the first time period is longer than the second time period, it is determined that the first sub-assembly and the second sub-assembly are in a set horizontal alignment. So that when the sub-packages to be identified are respectively arranged in the corresponding second package defining positions, if the read identification information corresponds to the first sub-package and the second sub-package respectively, indicating that the first sub-assembly and the second sub-assembly are in a set horizontal alignment;
when the split charging device is applied, a plurality of second split charging limiting positions are arranged on the split charging piece, the second split charging limiting positions can be first split charging limiting positions, the size of the second split charging limiting positions is generally just matched with the size of the sub split charging piece, the second split charging limiting positions can be arranged on the cover body of the split charging piece, so-called set horizontal alignment state is that the distance between the two split charging limiting positions is proper, and the second split charging limiting positions are positioned on two standard split charging limiting positions which are horizontal and vertical, so that the detection is facilitated. Therefore, the related method for setting the horizontal alignment state provided by the embodiment can simplify the identification of the actual transfer path.
As shown in fig. 6, as a preferred embodiment of the present invention, the method further includes:
step S50: detecting the contact area between the transfer clamping part and the first product under a set condition; the transferring clamping part is used for clamping the first product on the first sub-part the transfer is performed between the sub-package and the second sub-package, which comprises a mechanical arm or a manual hand, and in one scheme, when detecting the contact area, a prompt of symmetrical clamping is sent out, namely, the clamping and transferring of the first product are required to be realized through two symmetrical clamping points (the contact area is not smaller than the preset area caused by cladding clamping is avoided), for example, two fingers (clamping arms) are required to realize the clamping of the first product, so that the requirement that the contact area is smaller than the preset area is met; the detection of the contact area can be identified by including the clamping part and the first product partial image;
step S51: when the contact area is smaller than a preset area, acquiring a global image covering a theoretical transfer path; conversely, when the first product is clamped by the asymmetric clamping points, excessive contact with the first product can occur, and in this case, for a product with a smaller size, a product in which a hiding attempt is attempted to replace the first product is easy to occur, and this case cannot be identified or is difficult to identify through the global image; the global image needs to cover at least the theoretical transfer path, and when the theoretical transfer path is covered, the global image also covers the actual transfer path under the condition that the actual transfer path is similar to the theoretical transfer path, and the arrangement of the related acquisition devices of the global image can be closely arranged on the split charging pieces without additional arrangement;
step S52: identifying whether a non-first product exists on the actual transfer path based on the global image;
step S53: if so, determining that the actual transfer path does not conform to the theoretical transfer path of the first product between the first sub-package and the second sub-package. That is, based on the global image, when it is identified that a product other than the first product exists on the actual transfer path, under the set condition, even if the actual transfer path is similar to the theoretical transfer path between the first sub-package and the second sub-package, it is determined that the actual transfer path does not conform to the theoretical transfer path of the first product between the first sub-package and the second sub-package, whereas under the set condition, it is determined that the actual transfer path conforms to the theoretical transfer path of the first product between the first sub-package and the second sub-package, if it is identified that the product other than the first product does not exist on the actual transfer path, it is determined that the actual transfer path is similar to the theoretical transfer path of the first product between the first sub-package and the second sub-package;
in practice, the set conditions include that the ratio between the size of the first product and the length of the theoretical transfer path is smaller than the preset duty cycle. For the satisfaction of the above setting conditions, simply, the size of the first product is too small relative to the theoretical transfer path, so that the first product is easy to be replaced in the process of being transferred, that is, the replacement process is not easy to be found, because the theoretical transfer path is long, and any replacement point may not be easily monitored; resulting in a transferred non-first product; of course, if the quality traceability based severe detection requirement is met, the detection of steps S50-S53 may be performed even if the ratio between the size of the first product and the length of the theoretical transfer path is not smaller than the preset duty ratio.
It should be appreciated that, by adding detection under set conditions, especially for undersized products, the area of the product covered by the transfer nip during transfer may be too large, resulting in an excessive contact area, which may result in the first product being easily replaced during transfer and difficult to find, for example, by hiding another product in a certain position of the transfer nip for an opportunistic replacement, so that in this case, even if the actual transfer path for the first product meets the theoretical transfer path, there is a greater likelihood of replacement, and when the contact area is less than the predetermined area, additional detection of the global image may further enhance accurate detection of transfer, thereby ensuring that even for smaller sized products, safe transfer between the first sub-package and the second sub-package may be strictly ensured.
