[0021] like Figure 1 As shown, an embodiment of the present invention provides a method for generating a cigarette box QR code, comprising: Step S101, receiving production task information, determining the coding equipment and coding requirements based on the production task information, determining the coding timeline in combination with the production task information and equipment parameters of the coding equipment, and determining the cigarette box serial number according to the coding timeline.

[0022] Specifically, the production task information of cigarettes is received, wherein the production task information may include cigarette type, cigarette quantity, batch information, production date, etc., and the inkjet device and inkjet requirements of the QR code can be further determined according to the production task information, that is, according to the specific requirements of the production task information, such as (such as output, speed, accuracy, etc.), and the current task operation status of the inkjet device, the appropriate inkjet device is selected. Different inkjet devices may have different performance characteristics, such as different inkjet speeds, resolutions, inkjet widths, paper feed paper sizes, etc. The inkjet requirements may include error correction levels, including data content, etc., wherein the error correction level is an error correction capability that can be divided into four levels, from the lowest to the highest, namely L (about 7%), M (about 15%), Q (about 25%) and H (about 30%). The error correction level indicates that part of the content of the QR code is damaged or blocked, as long as it does not exceed the set error correction tolerance, such as a QR code with an L error correction level, as long as the damaged or blocked part does not exceed 7%, the original data can still be restored and the QR code data can be scanned and read. According to the production batch arrangement of the product in the production task information and the coding speed in the equipment parameters of the coding equipment, the coding time axis of the product is determined, wherein the coding time axis refers to the coding sequence time axis corresponding to the product. For example, in a batch of production task information, there are 3 batches of Class A cigarettes, A1, A2, A3, and 2 batches of Class B cigarettes, B1, B2. According to the equipment parameters, the coding time is designated from 2 o'clock to 4 o'clock, and the corresponding coding time axis can be: 2 o'clock-A1, 2:20-A2, 2:40-A3, 3 o'clock-B1, 3:30-B2. In addition, on this basis, each batch of cigarettes can be further divided into the coding time axis. For example, for the first batch of Class A cigarettes, which contains 1,000 packs of cigarettes, each pack, or every 10 packs of cigarettes, can be divided into the corresponding time axis, thereby realizing the reasonable planning of each stage in the production process. After dividing the time axis, the cigarette box serial numbers can be further divided. For example, when dividing the time axis of every 10 packs of cigarettes in the first batch of Class A cigarettes, the corresponding serial numbers can also be divided according to the same rules. For example, the serial numbers of the first batch of Class A cigarettes can be: A1-1 (first 10 packs), A1-2 (first 20 packs), A1-3 (first 30 packs)..., and the serial numbers of other batches can be deduced in the same way.

[0023] Step S102, based on the coding time axis, determine the task code and time code of the target cigarette box, and generate the QR code of the target cigarette box in combination with the coding requirement.

[0024] Specifically, based on the coding time axis of each batch of cigarettes in the production task information, the target cigarette boxes, that is, the task code and time code that should be sprayed on the cigarette boxes of each batch of cigarettes are determined, wherein the task code is a batch identifier of the cigarettes, which is used to identify the production information of the cigarettes such as the production batch and production line number, and the time code is a time identifier of the cigarettes, which is used to identify the corresponding production timestamp on the time axis when the cigarettes are produced. Combined with the coding requirements, such as the error correction level, the corresponding QR code is generated. The QR code generation steps can be specifically divided into four steps: data combination, encoding rules, error correction level, and QR code generation, including: 1. Data combination, combining the task code, time code and any other necessary information (such as relevant information of the cigarettes, serial number, anti-counterfeiting code, etc.) to form a complete data set; 2. According to the standard encoding rules of the QR code, converting the data set into a form that can be represented by the QR code; 3. According to the error correction level, adding appropriate redundant information to the data set to improve fault tolerance; 4. QR code generation, using the QR code generation software tool, the above data and parameters are used to generate an actual QR code image. In the process of generating the QR code, the physical requirements for spraying the QR code on the cigarette box can also be obtained, such as font, font size, QR code size, position, resolution, dryness, etc., so as to generate the QR code of the target cigarette box.

[0025] Step S103, detecting the image information of the two-dimensional code, determining the two-dimensional code level of the two-dimensional code based on the image information, and judging whether the two-dimensional code level meets the level requirement of the production task information.

[0026] Specifically, the image information of the two-dimensional code is obtained through an image acquisition device, the image information is analyzed, and the two-dimensional code level of the two-dimensional code is determined. The evaluation of the two-dimensional code level can be based on the ISO / IEC15415 standard or other relevant standards, and a series of parameters of the two-dimensional code image can be evaluated, including but not limited to decoding ability, symbol contrast, printing increment (modulation), axial inconsistency, and unused error correction capability. The two-dimensional code level standard can be divided into 5 levels from high to low, namely, A, B, C, D, and F. Decoding capability means that the entire data information can be successfully decoded, then the decoding is passed, and the decoding level is A, otherwise it is F; symbol contrast is used to measure the contrast between black modules and white modules. Good contrast helps improve reading speed and accuracy; printing increment measures the change in reflectivity of a single module in the QR code. Ideally, all black modules should have the same dark color, and white modules should also be uniformly bright; axial inconsistency reflects the consistency of the QR code pattern in the horizontal or vertical direction; unused error correction capability indicates the gap between the actual error correction capability used and the level set during design. If the QR code does not fully utilize its error correction function, it may indicate a potential problem. Evaluate the QR code level corresponding to the QR code according to the parameters, and judge whether the QR code level meets the level requirements of the production task information. In the above example, for general production task information, the four levels of ABCD are qualified levels, and the F level is unqualified.

[0027] Step S104, when the level of the two-dimensional code meets the level requirements of the production task information, extract the code to be checked from the two-dimensional code, obtain the task code and time code of the code to be checked, and compare them with the corresponding cigarette box serial number. When the comparison results match, output the result that the two-dimensional code is qualified.

[0028] Specifically, when the quality level of the QR code meets the level requirements of the production task information, it means that the QR code meets the physical printing requirements, and the data in the QR code needs to be verified. Among them, the object of verification can be extracted from the QR code, that is, the QR code is sampled, and the task code and time code of the sampled target are compared with the corresponding cigarette box serial number, wherein the number of samples can be determined according to the level requirements of the production task information. When the level requirements are higher, the more samples are sampled. The comparison includes two parts. One is to compare the task code with the cigarette box serial number, that is, to compare the task batch and production line in the task code with the cigarette box serial number on the spraying timeline, so as to determine whether there are problems with the production batch and production line in the cigarette production process. By comparing the task code, it can be confirmed whether the task information in the QR code is consistent with the task information recorded by the system. This helps to ensure that the QR code on each cigarette box correctly reflects the production batch and production line to which it belongs. Secondly, by comparing the time code with the cigarette box serial number, it can be determined whether the cigarettes were sprayed according to the spraying timeline during production. If they are not sprayed according to the spraying timeline, there may be time disorders on the time code such as string codes or garbled codes. By comparing the time code, it can be confirmed whether the time information in the QR code is consistent with the time information recorded by the system. This helps to ensure that the QR code on each cigarette box correctly reflects its production time and is produced according to the expected timeline. When the task code and time code of the sampling target are the same as the information in the corresponding cigarette box serial number, it means that there is no problem with the QR code data, and the QR code is output as qualified.

[0029] In addition, when the task code and time code of the code to be checked do not match the comparison result of the corresponding cigarette box serial number, obtain other two-dimensional codes within the preset range before and after the code to be checked on the coding time axis, wherein the preset range can be set according to the production task information, such as 5 minutes before and after, when the code to be checked does not match the cigarette box serial number, obtain all the two-dimensional codes of the code to be checked on the coding time axis before and after 5 minutes for further detection, when the comparison result is still that all the two-dimensional codes of 5 minutes before and after do not match, continue to expand the preset range, such as doubling to 10 minutes, and then detect again. Until the task code and time code of other two-dimensional codes are detected, they match the corresponding cigarette box serial number. The match at this time is that before and after the spraying time axis, there are task codes and time codes of other two-dimensional codes, which match the corresponding cigarette box serial number. Stop further detection at this time, and output the unmatched two-dimensional code and the corresponding cigarette box serial number with the comparison result within the preset range, so that the relevant staff can carry out subsequent maintenance work.

[0030] A method for generating a two-dimensional code for a cigarette box provided by an embodiment of the present invention receives production task information, determines the coding equipment and coding requirements based on the production task information, determines the coding timeline in combination with the equipment parameters of the production task information and the coding equipment, and determines the cigarette box serial number according to the coding timeline; determines the task code and time code of the target cigarette box based on the coding timeline, and generates the two-dimensional code of the target cigarette box in combination with the coding requirements; detects the image information of the two-dimensional code, determines the two-dimensional code level of the two-dimensional code based on the image information, and determines whether the two-dimensional code level meets the level requirements of the production task information; when the two-dimensional code level meets the level requirements of the production task information, extracts the code to be checked from the two-dimensional code, obtains the task code and time code of the code to be checked, and compares them with the corresponding cigarette box serial number, and when the comparison results match, outputs the result of the qualified two-dimensional code. In this way, it can be ensured that the two-dimensional code on the cigarette box is not only up to standard in terms of physical printing quality, but also accurate in terms of the data content of the cigarette. This not only improves the reliability of the production process, but also enhances the traceability and safety of the product.
