Description

Technical Field

[0001] The present invention relates to the technical field of concrete testing, and in particular to a concrete test block anti-counterfeiting system and an anti-counterfeiting method. Background Art

[0002] In order to monitor the quality of concrete during construction, concrete test pieces are made and then tested and evaluated by a third-party testing agency with relevant qualifications. In this process, in order to prevent the test pieces from being replaced, the industry has designed some anti-counterfeiting methods.

[0003] The more common ones are: labels, identification codes and other forms. However, there are some problems. 1) Easy to forge: Anti-counterfeiting measures are easy to be imitated or cracked, especially those anti-counterfeiting marks that only rely on printed patterns or simple codes; due to the low technical threshold of anti-counterfeiting means, there is a lack of effective encryption mechanisms or physical protection measures. 2) Poor reliability: Traditional anti-counterfeiting labels or markers are easy to fall off or damage during concrete pouring, maintenance, transportation, and testing, especially in humid or high temperature environments; the main reason is that the material selection is improper or the fixing method is not strong enough to withstand the mechanical stress and other external forces during the construction process. 3) Inconvenient data management: Existing inspection and supervision often rely on manual records, information is not updated in time, and it is easy to lose or misrecord; the main reason is the lack of unified data standards and automated data collection methods. 4) Low verification efficiency: The current verification process usually requires manual verification of a large number of paper documents or spreadsheets, which is time-consuming and error-prone; one of the reasons is that there is no efficient information interaction platform, which makes the verification work cumbersome and complicated. 5. Lack of environmental adaptability: Some anti-counterfeiting products perform poorly in specific construction environments. For example, they may fail in low temperature or corrosive environments. The main reason is that the actual conditions of the construction site and the weather resistance requirements of long-term exposure to the outside are not fully considered during the design.

[0004] In further improvements, the industry has designed some new anti-counterfeiting methods in combination with information technology. For example, the patent with application number "2019108664573" discloses an anti-counterfeiting card for on-site witness sampling and implantation of concrete and its verification method, including an identification card with an identification code printed on the surface, including at least one barbed pin, the barbed pin is arranged at the edge of the identification card and can be bent and inserted into concrete, the identification code is arranged on the surface of the identification card; a scale capable of indicating distance and / or angle is arranged on the surface of the identification card; a positioning piece with a reference pattern for measurement is arranged on the surface, which is arranged next to the identification card, and the reference pattern and the scale form a relative position relationship; in this scheme, the relative position relationship between the barbed pin, the identification code, the scale and the reference pattern constitutes an anti-counterfeiting feature, sampling and recording on site, and anti-counterfeiting verification is detected at the inspection station, which can effectively prevent the concrete inspection piece from being swapped.

[0005] The above disclosed solution has stronger environmental adaptability and more reliable anti-counterfeiting effect.

[0006] The applicant further designed a plan based on the actual needs of the project to more reliably and comprehensively prevent the counterfeiting of concrete test blocks and enhance the reliability and comprehensiveness of the information. Summary of the invention

[0036] If the error is within the allowable range, upload the data together with the test block sample;

[0037] If the error exceeds the allowable range, the identification anti-counterfeiting label card is marked as invalid; and the process returns to step S2 and operates again.

[0038] In some embodiments, step S5 further includes: after photographing the pattern, writing a timestamp into the anti-counterfeiting label card, and attaching an RFID shielding film;

[0039] Step S7 also includes: after scanning and identification, peeling off the anti-counterfeiting label card, reading the timestamp, and comparing it with the data recorded on the server; if they are inconsistent, it is determined that the test block has been replaced;

[0060] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0061] Reference Figure 1-9 A concrete test block anti-counterfeiting system includes an anti-counterfeiting label card, and a sample preparation end and a laboratory end that communicate with a server and identify the anti-counterfeiting label card.

[0062] Among them, the sample preparation end and the laboratory end are set to multiple to accommodate more users.

[0063] Furthermore, the server is also connected to the supervision platform to report the inspection information, enabling multi-subject access by construction units, third-party inspection agencies, and government departments, with more comprehensive and reliable coverage.

[0064] Specifically, the anti-counterfeiting label card is implanted into the surface of the concrete test block to expose the identification area; after the laboratory obtains the basic information, the anti-counterfeiting verification is performed by identifying the installation position, angle, and distance of the anti-counterfeiting label card; during the operation, the relevant data can be obtained and the authenticity can be verified by scanning and sensing the anti-counterfeiting label card, which simplifies the verification process, improves work efficiency and accuracy, and the entire data is informationized, stored in the cloud, and shared by multiple entities.

[0065] Correspondingly, the sample preparation end is an intelligent terminal or smart phone equipped with a camera, a level, and a GPS component; the laboratory end is a host equipped with a camera; it can be understood that the laboratory host communicates with each testing instrument, associates the test block identification information with the test information, and uploads the test block's test information to the supervision platform accordingly.

[0066] In some embodiments, the anti-counterfeiting label card includes: a substrate 1 , an identification code 2 and a direction mark 3 arranged on the front side of the substrate 1 , and a bending leg 4 for fixing the substrate 1 .

[0067] Among them, for the identification code 2, a QR code combined with a visible code can be selected.

[0068] As in Figure 2 , 3 In the code, identification code 2 is set to two forms: QR code and digital + English readable code. The QR code is easy for the equipment to scan and identify, has a certain fault tolerance, and is still readable when it is damaged to a certain extent, maintaining high availability; the readable code is used for manual identification, which is convenient for personnel to quickly identify the basic information of the test block.

[0069] Specifically, the QR code uses an encryption algorithm to generate a unique code (the encryption algorithm can be designed by yourself or a public algorithm is used, which is a conventional application and will not be described here), so that each anti-counterfeiting label card has a unique digital signature, which improves the anti-counterfeiting performance, reduces the risk of counterfeiting, and effectively prevents copying and forgery. In addition, important parameters such as production information and quality inspection data are stored synchronously and associated, and can be quickly identified and read through handheld devices, realizing comprehensive information management of concrete samples and facilitating tracking and query.

[0070] For the direction indicator 3, a triangle mark or an arrow is used to facilitate quick confirmation of the basic direction.

[0071] Furthermore, a plurality of alignment identification lines 5 are arranged around the upper surface of the substrate 1 to assist in positioning and enhance accuracy.

[0072] like Figure 2 , 3 As shown, the alignment identification lines 5 are arranged radially around the center of the circle and avoid the area where the two-dimensional code is located; it cooperates with the direction mark 3 to facilitate rapid alignment and identification of the high-precision position of the anti-counterfeiting label card.

[0073] In some embodiments, the base sheet 1 and the bending leg 4 are integrally formed and made of plastic material; and preferably, a high-temperature resistant plastic type is used so that it can withstand extreme conditions such as high temperature and high humidity during the concrete curing process and maintain its functions intact, thereby enhancing the scope of application of the product and adapting to various construction environments.

[0074] Among them, the bending foot 4 is a plurality of arrow structures arranged in a surrounding manner; in the normal state, the bending foot 4 and the substrate 1 are in a flat state, and the overall structure is a planar structure, which is convenient for production, storage, transportation and other processes; during installation, the bending foot 4 is bent downward so that it is perpendicular to the substrate and directly inserted into the concrete test block; after the arrow is inserted, it has good stability and pull-out resistance; through this structural design that is easy to implant in concrete, the card is well combined with the concrete, and it is not easy to fall off or be damaged, thereby ensuring the stability and reliability of the anti-counterfeiting card.

[0075] It is understandable that the material of the anti-counterfeiting label card should have a certain flexibility so that it is not easy to break when the bending leg 4 is bent, and maintains a good integrated shape.

[0076] like Figure 2 , 3 , as shown in 4; the substrate 1 is set as a circular structure; there are four bending feet 4 arranged around it, and the four arrow-shaped bending feet 4 form a backward hook-type rivet; the direction mark at the upper position is the reference direction. When preparing samples, collecting samples and conducting experiments, the arrow clock is pointed forward for basic positioning, so as to cooperate with the identification of the installation position, angle and distance of the anti-counterfeiting label card; the QR code in the middle position is a unique code and will not be repeated; when preparing samples and collecting samples, the QR code is scanned to enter relevant information; during the experiment, the camera recognizes the QR code information, and the test block information and experimental data are automatically reported to the supervision platform after the experiment; the code below the QR code is also the unique label code, which will not be repeated and can be set according to the standardized coding format such as company name and project name; the company or project abbreviation, or other readable information is set at the bottom to quickly obtain the basic information of the test block; for example, YLTZ in the figure is the company abbreviation, which can quickly identify the production unit.

[0077] In some embodiments, an RFID chip is disposed in the substrate 1 .

[0078] Correspondingly, RFID reading and writing components are provided at the sample preparation end and the laboratory end.

[0079] At the same time, the RFID chip counts and records each read and write operation; by detecting the number of read and write operations, anti-counterfeiting can be further enhanced.

[0080] It is understandable that in normal operation, the number of times the RFID chip is read and written is relatively fixed (the number of operations of the sample preparation unit and the laboratory unit is basically fixed). If the number of times the RFID chip is read and written is obviously too many, it is possible that the anti-counterfeiting label card has been read and written without authorization, and there is a risk of information leakage and attack; at this time, it should be questioned; and the sample preparation unit and the laboratory should communicate to determine whether it is still available.

[0081] Furthermore, a transparent RFID shielding film is attached to the upper surface of the substrate 1 .

[0082] It should be noted that the transparency of the RFID shielding film does not need to be very high, but it should not affect the reading of the identification code 2.

[0083] The RFID shielding film has: a first state in which the anti-counterfeiting label card is pasted after being placed in place, and a second state in which the anti-counterfeiting label card is removed before laboratory verification.

[0084] Therefore, the RFID shielding film can not only isolate unauthorized information interaction, but also form a protective film to reduce damage to the surface of the anti-counterfeiting label card during maintenance and transportation.

[0085] In addition, a simple anti-counterfeiting film is formed, which can be discovered if it is peeled off by someone.

[0086] Furthermore, RFID shielding film can be combined with common anti-counterfeiting film technology (such as the anti-counterfeiting technology of peeling off the bottom, setting a bottom pattern in a position that does not affect the information on the label card; fragile sticker technology, adding a circle of fragile stickers on the outer circle of the RFID shielding film; etc.) to further enhance its anti-counterfeiting performance.

[0087] In some embodiments, the edge of the substrate 1 is provided with notches at random positions.

[0088] Among them, the gap is cut manually before placement; thus, the unpredictability and randomness of manual processing can be used to further enhance the overall anti-counterfeiting (the gap is photographed and uploaded, and can be automatically identified by the equipment, or manually compared and identified).

[0089] A concrete test block anti-counterfeiting method adopts the above-mentioned concrete test block anti-counterfeiting system.

[0090] The method for preventing counterfeiting of concrete test blocks comprises the following steps: S1, identity authentication → S2, basic information input → S3, placement information generation → S4, placement of anti-counterfeiting label card → S5, test block pattern upload → S6, test block sampling and inspection → S7, laboratory sample collection → S8, pre-experimental verification → S9, experimental pattern upload → S10, data reporting.

[0091] S1. Identity authentication: The operator at the sample preparation end authenticates his identity and logs in after passing the authentication.

[0092] Among them, identity authentication adopts the forms of face recognition, SMS password, account password, etc.; it is sufficient to be able to identify the identity and authority of the operator.

[0093] S2. Basic information input: Scan the identification code of the anti-counterfeiting label card, enter the project name and location information; locate the current location and compare it with the geographical location of the project; if the comparison is consistent, upload the input information; if the comparison is inconsistent, an error message will be prompted and the entry will be rejected.

[0094] S3, placement information generation: call the camera, and display the auxiliary lines on the screen; after the test block is inserted, the placement position and placement angle are randomly generated and simulated on the screen.

[0095] In this step, information is randomly generated by the system and is completely unpredictable, which significantly enhances the overall anti-counterfeiting performance and has high reliability.

[0096] Among them, Figure 4 As shown; the auxiliary lines include nine-square grid lines or sixteen-square grid lines, a horizontal prompt box, and a test block edge box and an anti-counterfeiting label card edge box of corresponding proportions.

[0097] During operation, first place the sample preparation end to a horizontal state according to the horizontal prompt box.

[0098] After that, move the test block edge frame to the concrete test block at an appropriate distance.

[0099] Then, the system randomly generates the placement position and angle, and simulates the display on the screen.

[0100] At the same time, a picture is taken after the random information is generated, and a simulated anti-counterfeiting label card is displayed on the picture; it is convenient for operators to view the picture and place the anti-counterfeiting label card.

[0101] It is understandable that after taking a photo, there is no need to pay attention to the position of the sample making end; just put it aside and place the anti-counterfeiting label card while looking at the photo; there is no need to hold the sample making end all the time to avoid the problem of inconvenience in operation caused by camera shaking.

[0102] It is understandable that when placing the anti-counterfeiting label card, a ruler or an angle ruler can be used to assist in positioning.

[0103] In the specific operation, first hold the sample-making end and place it above the concrete test block; with the help of the nine-square grid lines or sixteen-square grid lines, place the concrete test block in the middle of the screen; adjust the distance from the concrete test block according to the size and overlap of the test block boundary frame and the test block; at the same time, according to the real-time feedback of the horizontal prompt box, place the sample-making end in a relatively horizontal state; when the level is maintained and the test block boundary frame overlaps with the test block, automatically take a picture and randomly generate the placement position and placement angle, which are simulated and displayed on the screen.

[0104] like Figure 4In the example; with direction mark 3 as the basic direction mark, the anti-counterfeiting mark card is located in the upper left position of the concrete test block; the specific angle is that the central vertical axis of the concrete test block is offset 10.4 cm to the upper left, and the included angle is 40.5 degrees.

[0105] It can be understood that the center of the test block is positioned at the intersection of the horizontal and vertical auxiliary lines formed in the middle position of the side edges of the test block edge frame; the center of the anti-counterfeiting label card is positioned at the center of the circle of the anti-counterfeiting label card edge frame in conjunction with the radially arranged alignment identification lines 5; the size of the anti-counterfeiting label card is fixed, and the size of the sample also has specific specifications, which makes it extremely convenient to locate the center with good accuracy.

[0106] S4. Place the anti-counterfeiting label card: insert the anti-counterfeiting label card into the uncured concrete test block according to the generated placement position and angle.

[0107] Wherein, in step S4, the anti-counterfeiting label card is flush with the upper surface of the concrete test block.

[0108] During the specific operation, first bend the bending leg 4 downward until it is perpendicular to the substrate 1; then, press and insert it directly into the uncured concrete test block; the side containing the QR code faces upward, and the insertion depth makes the QR code plane flush with the test block plane; it should be noted that the direction mark 3 should face the front position (it can face the front, including the front left, the front right, and it is not required to face the front) to locate the relative position of the anti-counterfeiting label card and the test block.

[0109] like Figure 4 In the example, the anti-counterfeiting label card is located at the upper left position of the concrete test block; similarly, when the anti-counterfeiting label card is located at the lower left or lower right position of the concrete test block, the direction indicator 3 should also face the front position.

[0110] S5. Upload the test block pattern: Take a picture of the test block after placement and upload it.

[0111] Specifically, step S5 includes the following steps:

[0112] Place the sample preparation end to a horizontal state according to the horizontal prompt box;

[0113] Move the test block edge frame to the appropriate distance to match the concrete test block;

[0114] Automatically identify and adjust the position of the border frame of the anti-counterfeiting label card to overlap with the anti-counterfeiting label card;

[0115] Identify the direction indicator and midpoint of the anti-counterfeiting label card, calculate the installation direction, angle and distance of the anti-counterfeiting label card, and compare them with the data randomly generated in step S3;

[0116] If the error is within the allowable range, upload the data together with the test block sample;

[0117] If the error exceeds the allowable range, the identification anti-counterfeiting label card is marked as invalid; and the process returns to step S2 and operates again.

[0118] The above operation interface is similar to step S3, which can be referred to Figure 4 .

[0119] Optionally, step S5 also includes: after photographing the pattern, writing a timestamp into the RFID chip of the anti-counterfeiting label card, and pasting an RFID shielding film; thereby locally recording the photographing time, and shielding and protection being formed by the RFID shielding film.

[0120] S6. The test blocks are sampled and sent for inspection. According to the maintenance requirements, the test blocks are sent to the laboratory after being sampled.

[0121] S7. Laboratory sample collection: Scan the identification code of the anti-counterfeiting label card, obtain the information and verify it; if the test block information is consistent with the entrusted information, complete the sample collection registration and upload the sample collection record; if the information is inconsistent, it is judged that the test block has been replaced.

[0122] It is understandable that, in addition to the host, the laboratory end can also be equipped with an intelligent terminal or smart phone with a camera and RFID reading and writing components to form a handheld terminal as a sample receiving end, which is used for QR code scanning and RFID reading and writing operations when collecting samples; wherein, the sample receiving end can directly communicate with the server, or communicate with the laboratory end through the intranet; similarly, the sample receiving end is also set to be several.

[0123] Optionally, step S7 also includes:

[0124] After scanning and identification, peel off the anti-counterfeiting label card; read the timestamp and compare it with the data recorded on the server; if they are inconsistent, it is determined that the test block has been replaced.

[0125] Furthermore, step S7 also includes:

[0126] Read the RFID chip count record. If the number of read and write times is obviously beyond the normal range, question the test block and send an inquiry to the sample preparation unit. If there is no reasonable explanation, the test block is judged to be abnormal and will not be accepted.

[0127] S8. Verification before the experiment: Use the camera connected to the host to identify the installation position, angle, and distance of the anti-counterfeiting label card, and compare it with the test block data uploaded by the sample preparation end; if they are consistent, the experiment can be carried out; if they are inconsistent, it is judged to be replaced.

[0128] It can be understood that a fixed sample placement position and a corresponding camera position are set up in the laboratory; after the sample is placed in place, the camera can quickly focus, identify, and make an anti-counterfeiting judgment; the anti-counterfeiting judgment process is similar to step S5, identifying the direction mark and midpoint of the anti-counterfeiting label card, calculating the installation direction, angle, and distance of the anti-counterfeiting label card, and comparing the data with the information uploaded in step S5.

[0129] S9. Upload the experimental pattern: take a picture of the test block in the detection status and upload it.

[0130] S10. Data reporting: Experimental data is uploaded to the supervision platform.
