Description

Technical Field

[0001] The present invention relates to the technical field of printing management, in particular to an intelligent management system and method for multi-task continuous printing of a single-pass printer. Background Art

[0002] A single-pass printer is a device that completes printing in a single pass of the print head or print media through the print area. In the packaging industry, marking, coding, and pattern printing on cartons, cardboard, wood, and other products are important steps in the production process and are often achieved using single-pass printers.

[0003] A Chinese invention patent with publication number CN116991341A discloses an IoT-based intelligent printing device management system and method. The system can adaptively adjust the order in which documents are printed, effectively reducing the problem of users being unable to print documents in a timely manner due to emergencies. However, in actual use, it is difficult to effectively monitor and control the entire process before, during, and after printing. Management personnel are unable to quickly implement reasonable improvement measures, making printing management difficult.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent management system and method for multi-task continuous printing of a single-pass printer, which solves the problem that the existing technology is difficult to achieve effective monitoring and control of the entire process of a single-pass printer before, during and after printing, and the management personnel are unable to make reasonable improvement measures in time, resulting in great difficulty in printing management.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An intelligent management system for multi-task continuous printing of a single-pass printer includes a multi-task parallel management module, a printing impact analysis module, a printing execution monitoring module, a printing quality comparison and analysis module, and an abnormality warning module. The multi-task parallel management module receives all printing tasks from user terminals, sorts the tasks according to user needs and time sequence, and enables the single-pass printer to execute all printing tasks according to the task sorting.

[0008] Before the printing operation of the corresponding printing task, the printing impact analysis module analyzes the adverse factors affecting the printing operation and generates a high-impact printing signal or a low-impact printing signal, and sends the high-impact printing signal to the abnormal warning module;

[0009] When a low-impact print signal is generated, the single-pass printer starts printing the corresponding print task. The print execution monitoring module monitors the printing operation and determines its printing performance. By analyzing the performance, it generates a good print signal or a bad print signal, and sends the bad print signal to the abnormal warning module.

[0010] At the end of the printing operation of the corresponding printing task, the print quality comparison and analysis module collects the image of the printing area on the corresponding printing object and marks it as the printing area image. Through image recognition technology and based on the printing area image and the corresponding standard image, the printing quality is judged, and a good print quality signal or a poor print quality signal is generated accordingly, and the poor print quality signal is sent to the abnormal warning module; the abnormal warning module issues a corresponding warning when it receives a high-impact print signal, a poor print signal or a poor print quality signal.

[0011] Furthermore, the specific analysis process of the print impact analysis module includes:

[0012] The actual positions of several contour points on the object to be printed are obtained, and the deviation distance of the actual position of the corresponding contour point compared with the corresponding preset standard position is marked as the contour distance measurement value. The contour distance measurement value is numerically compared with the preset contour distance measurement threshold. If the contour distance measurement value exceeds the preset contour distance measurement threshold, the corresponding contour point is marked as an out-of-position contour point; if there is an out-of-position contour point on the object to be printed, a printing high-impact signal is generated;

[0013] If there are no unplaced contour points on the object to be printed, the contour distance measurement values ​​of all contour points are averaged to obtain the in-place accuracy coefficient, and the in-place accuracy coefficient is numerically compared with the preset in-place accuracy coefficient threshold. If the in-place accuracy coefficient exceeds the preset in-place accuracy coefficient threshold, a printing high impact signal is generated.

[0014] Furthermore, if the in-place accuracy coefficient does not exceed the preset in-place accuracy coefficient threshold, the ambient temperature and ambient humidity of the environment in which the single-pass printer is located are collected, and the difference between the ambient temperature and the median of the set standard suitable printing environment temperature range is calculated and the absolute value is taken to obtain the printing environment temperature measurement value. Similarly, the printing environment humidity measurement value is obtained;

[0015] The dust concentration and wind speed of the environment where the single-pass printer is located are collected and marked as the printing environment gray measurement value and the printing environment wind measurement value respectively. The printing environment comprehensive inspection value is obtained by weighted summing the printing environment temperature measurement value, the printing environment humidity measurement value, the printing environment gray measurement value and the printing environment wind measurement value;

[0016] And through the analysis of the printer power supply stability, the power supply impact comprehensive inspection value is obtained, and the printing environment comprehensive inspection value and the power supply impact comprehensive inspection value are numerically compared with the preset printing environment comprehensive inspection threshold and the preset power supply impact comprehensive inspection threshold respectively. If the printing environment comprehensive inspection value or the power supply impact comprehensive inspection value exceeds the corresponding preset threshold, a high printing impact signal is generated; if both the printing environment comprehensive inspection value and the power supply impact comprehensive inspection value do not exceed the corresponding preset threshold, a low printing impact signal is generated.

[0017] Furthermore, the specific analysis process of the printer power supply stability analysis is as follows:

[0018] The current and voltage of a single-pass printer at all times within a unit time are collected, and the variance of all currents within a unit time is calculated to obtain the printer flow wave value, and similarly, the printer pressure wave value is obtained; and when the current or voltage is not within the corresponding preset range, the single-pass printer is judged to be in a power stability state, and the proportion of the time that the single-pass printer is in the power stability state within a unit time is marked as the printer power abnormality value. The power supply impact comprehensive inspection value is obtained by numerically calculating the printer flow wave value, the printer pressure wave value and the printer power abnormality value.

[0019] Furthermore, the specific analysis process of the print execution monitoring module includes:

[0020] The print execution monitoring value is obtained through analysis, and the print execution monitoring value is compared with the preset print execution monitoring threshold. If the print execution monitoring value exceeds the preset print execution monitoring threshold, a print poor signal is generated; if the print execution monitoring value does not exceed the preset print execution monitoring threshold, a print good signal is generated.

[0021] Furthermore, the analysis and acquisition method of printing execution monitoring values ​​is as follows:

[0022] The real-time printing speed of the single-pass printer is collected, and the deviation value of the real-time printing speed compared with the set standard printing speed is marked as the printing speed detection value; the print head of the single-pass printer is monitored to collect the inkjet pressure and inkjet flow, and the deviation value of the inkjet pressure compared with the set standard inkjet pressure is marked as the inkjet pressure detection value, and the deviation value of the inkjet flow compared with the set standard inkjet flow is marked as the inkjet volume detection value; and the deviation value of the temperature of the ink to be ejected in the single-pass printer from the set standard ink temperature is marked as the inkjet temperature detection value; the printing execution monitoring value is obtained by numerically calculating the printing speed detection value, the inkjet pressure detection value, the inkjet volume detection value and the inkjet temperature detection value.

[0023] Furthermore, the specific analysis process of the print quality comparison and analysis module is as follows:

[0024] Based on the printing area image and the corresponding standard image, it is judged whether the printed text and pattern are clear, and the fuzzy ghosting part is identified. If the fuzzy ghosting part exists, the area of ​​the corresponding fuzzy ghosting part is marked as an unqualified surface condition value, and the unqualified surface condition value is compared with a preset unqualified surface condition threshold. If the unqualified surface condition value exceeds the preset unqualified surface condition threshold, the corresponding fuzzy ghosting part is marked as a quality-unusual part; if the quality-unusual part exists on the printed object, a print quality-unusual signal is generated;

[0025] If there is no quality-abnormal part on the printed object, a print quality evaluation value is obtained through print quality normalization analysis, and the print quality evaluation value is numerically compared with the preset print quality evaluation threshold. If the print quality evaluation value exceeds the preset print quality evaluation threshold, a print quality abnormality signal is generated; if the print quality evaluation value does not exceed the preset print quality evaluation threshold, a print quality good signal is generated.

[0026] Furthermore, the specific analysis process of print quality normalization analysis is as follows:

[0027] The printing area image is divided into several square grids through image segmentation technology, and the color difference data of the corresponding square grids are collected. The color difference data of all square grids are averaged to obtain the printing color difference detection value, and the proportion of square grids whose color difference data exceeds the preset color difference data threshold is marked as a high color difference proportion value;

[0028] The areas of all blurred ghosting parts are summed up to obtain the total blurred ghosting value, and the ratio of the total blurred ghosting value to the total area of ​​the printing area image is calculated to obtain the blurred ghosting detection value; the printing quality evaluation value is obtained by numerically calculating the printing color difference detection value, the high color difference occupancy value and the blurred ghosting detection value.

[0029] Furthermore, the abnormality warning module is communicatively connected to the printer quality inspection module. The printer quality inspection module is used to set a detection period, comprehensively evaluate the operating status of the single-pass printer during the detection period, generate a quality inspection pass signal or a quality inspection abnormality signal through analysis, and cause the abnormality warning module to issue an alarm when the quality inspection abnormality signal is generated. The specific analysis process is as follows:

[0030] The number of times a poor print signal is generated during a detection period is collected and the ratio is calculated with the total printing time of a single-pass printer during the detection period to obtain a poor print detection value, and the number of times a poor print signal is generated during the detection period is collected and the ratio is calculated with the number of print objects that have been printed during the detection period to obtain a poor print detection value;

[0031] The printer quality inspection value is obtained by assigning weights and summing the print defect detection value and the print quality abnormality detection value, and the printer quality inspection value is numerically compared with the preset printer quality inspection threshold. If the printer quality inspection value exceeds the preset printer quality inspection threshold, a quality inspection abnormality signal is generated; if the printer quality inspection value does not exceed the preset printer quality inspection threshold, a quality inspection pass signal is generated.

[0032] Furthermore, the present invention proposes a method for intelligently managing multi-task continuous printing of a single-pass printer, comprising the following steps:

[0033] Step 1: sorting tasks according to user needs and time sequence, and making the single-pass printer execute all printing tasks according to the task sorting;

[0034] Step 2: Before the printing operation of the corresponding printing task, analyze the adverse factors affecting the printing operation and generate a high-impact printing signal or a low-impact printing signal;

[0035] Step 3: When the low-impact print signal is generated, the single-pass printer is caused to execute the corresponding print task, and the print operation is monitored and its print performance is judged, and a print quality signal or a print quality signal is generated through analysis;

[0036] Step 4: When the printing operation of the corresponding print task is completed, the print quality is judged based on the print area image and the corresponding standard image by image recognition technology, and a good print quality signal or a poor print quality signal is generated accordingly;

[0037] Step 5: When a high-impact printing signal, a poor-quality printing signal, or a poor-quality printing signal is generated, the abnormal warning module issues a warning.

[0038] Furthermore, the present invention proposes a computer storage medium having a computer program stored thereon, which, when executed by a processor, implements an intelligent management method for multi-task continuous printing of a single-pass printer.

[0039] Furthermore, the present invention proposes a computer device comprising a processor and a memory; the memory stores a computer program, and the processor executes the computer program stored in the memory, so that the computer device executes a single-pass printer multi-task continuous printing intelligent management method.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. In the present invention, all print tasks are sequenced through a multi-task parallel management module to ensure continuous and efficient completion of tasks. Before the printing operation of a corresponding print task, adverse factors affecting the printing operation are analyzed. When a low-impact print signal is generated, the single-pass printer starts the printing operation of the corresponding print task and its printing performance is judged in real time. Furthermore, the print quality of the corresponding print task is judged at the end of the printing operation. This enables effective supervision of the entire process before, during, and after printing, significantly reducing the management difficulty for managers and facilitating the implementation of large-scale, multi-task printing operations.

[0042] 2. In the present invention, the operating status of the single-pass printer during the detection period is comprehensively evaluated through the printer quality inspection module, and a quality inspection qualified signal or a quality inspection abnormality signal is generated through analysis. When the quality inspection abnormality signal is generated, the abnormal warning module issues a warning to remind the management personnel to inspect and repair the single-pass printer in time, ensure the subsequent stable operation of the single-pass printer and improve the printing effect. It has a high degree of intelligence, which further reduces the management difficulty of the management personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1: Figure 1 As shown, the present invention proposes an intelligent management system for multi-task continuous printing of a single-pass printer, which includes a multi-task parallel management module, a printing impact analysis module, a printing execution monitoring module, a printing quality comparison and analysis module, and an abnormality warning module;

[0049] The multi-task parallel management module receives all printing tasks from user terminals, sorts the tasks according to user needs and time sequence, and enables the single-pass printer to execute all printing tasks according to the task sequence, ensuring that the tasks are completed continuously and efficiently;

[0050] Before the printing operation of the corresponding print task, the print impact analysis module analyzes the adverse factors affecting the printing operation and generates a high-impact print signal or a low-impact print signal. The high-impact print signal is sent to the abnormal warning module. Upon receiving the high-impact print signal, the abnormal warning module issues a corresponding warning to remind the management personnel to temporarily suspend the printing operation and take corresponding control measures in a timely manner, thereby reducing the degree of adverse impact on printing quality and reducing the management difficulty of the management personnel. The specific analysis process of the print impact analysis module is as follows:

[0051] The actual positions of several contour points on the object to be printed are obtained, and the deviation distance of the actual position of the corresponding contour point compared with the corresponding preset standard position is marked as the contour distance measurement value. The contour distance measurement value is numerically compared with the preset contour distance measurement threshold. If the contour distance measurement value exceeds the preset contour distance measurement threshold, it indicates that the position deviation of the corresponding contour point is large, and the corresponding contour point is marked as a contour point that is not in place;

[0052] If there are any in-place contour points on the object to be printed, indicating that the position accuracy of the object to be printed is low, a high-impact printing signal is generated;

[0053] If there are no out-of-place contour points on the object to be printed, the contour distance measurement values ​​of all contour points are averaged to obtain the in-place accuracy coefficient, and the in-place accuracy coefficient is numerically compared with the preset in-place accuracy coefficient threshold. If the in-place accuracy coefficient exceeds the preset accuracy coefficient threshold, it indicates that the position accuracy of the object to be printed is low, and a high-impact printing signal is generated.

[0054] Furthermore, if the in-place accuracy coefficient does not exceed a preset in-place accuracy coefficient threshold, indicating that the position accuracy of the object to be printed is high, the ambient temperature and ambient humidity of the environment in which the single-pass printer is located are collected, and the difference between the ambient temperature and the median value of the set standard suitable printing environment temperature range is calculated and the absolute value is taken to obtain a printing environment temperature measurement value, and the difference between the ambient humidity and the median value of the set standard suitable printing environment humidity range is calculated and the absolute value is taken to obtain a printing environment humidity measurement value;

[0055] and collecting the dust concentration and wind speed of the environment where the single-pass printer is located and marking them as the printing environment dust measurement value and the printing environment wind measurement value respectively;

[0056] The print environment comprehensive inspection value Gs is calculated by weighting and summing the print environment temperature measurement value Gy, the print environment humidity measurement value Gp, the print environment ash measurement value Ge, and the print environment wind measurement value Gf using the formula Gs = (b1*Gy+b2*Gp+b3*Ge+b4*Gf) / 4. b1, b2, b3, and b4 are preset proportional coefficients greater than zero. A larger value of the print environment comprehensive inspection value Gs indicates a worse print environment and a greater adverse impact on print quality.

[0057] The current and voltage of a single-pass printer at all times within a unit time are collected, and the variance of all currents within the unit time is calculated to obtain a printer current wave value, and the variance of all voltages within the unit time is calculated to obtain a printer pressure wave value; and the current and voltage are numerically compared with corresponding preset ranges, and when the current or voltage is not within the corresponding preset range, the single-pass printer is determined to be in a power stability abnormality state, and the proportion of the time that the single-pass printer is in the power stability abnormality state within the unit time is marked as a printer power abnormality value;

[0058] By formula The printer flow wave value Lp, the printer pressure wave value Ls, and the printer electrical anomaly value Le are numerically calculated to obtain a power supply impact comprehensive inspection value Lg; wherein rw1, rw2, and rw3 are preset proportional coefficients with values ​​greater than zero, and a larger value of the power supply impact comprehensive inspection value Lg indicates a worse power supply condition for the single-pass printer, and a greater adverse impact on print quality.

[0059] The printing environment comprehensive inspection value Gs and the power supply impact comprehensive inspection value Lg are numerically compared with the preset printing environment comprehensive inspection threshold and the preset power supply impact comprehensive inspection threshold respectively. If the printing environment comprehensive inspection value Gs or the power supply impact comprehensive inspection value Lg exceeds the corresponding preset threshold, it indicates that the adverse impact on the printing quality is generally large, and a high-impact printing signal is generated; if the printing environment comprehensive inspection value Gs and the power supply impact comprehensive inspection value Lg do not exceed the corresponding preset threshold, it indicates that the adverse impact on the printing quality is generally small, and a low-impact printing signal is generated.

[0060] When the low-impact printing signal is generated, the single-pass printer starts the printing operation of the corresponding printing task. It should be noted that the single-pass printer uses a high-precision print head to achieve high-definition and high-precision printing on the surfaces of materials such as cartons, cardboards, and wood boards, and supports multiple printing modes (such as text, barcodes, QR codes, patterns, etc.) to meet different printing needs.

[0061] The print execution monitoring module monitors the print operation and determines its printing performance. Through analysis, it generates a good print signal or a poor print signal, and sends the poor print signal to the abnormal warning module. Upon receiving the poor print signal, the abnormal warning module issues a corresponding warning, reminding the management personnel to investigate the cause and take corresponding improvement measures, thereby ensuring the stable and efficient printing operation and improving the print quality, significantly reducing the management difficulty of the management personnel. The specific analysis process of the print execution monitoring module is as follows:

[0062] The real-time printing speed of the single-pass printer is collected, and the deviation of the real-time printing speed from the set standard printing speed is marked as a printing speed detection value; the print head of the single-pass printer is monitored to collect inkjet pressure and inkjet flow rate, and the deviation of the inkjet pressure from the set standard inkjet pressure is marked as an inkjet pressure detection value, and the deviation of the inkjet flow rate from the set standard inkjet flow rate is marked as an inkjet volume detection value; and the deviation of the temperature of the ink to be ejected in the single-pass printer from the set standard ink temperature is marked as an inkjet temperature detection value;

[0063] The print execution monitoring value YL is obtained by numerically calculating the print speed detection value WP, the inkjet pressure detection value WY, the inkjet volume detection value WS, and the inkjet temperature detection value WN using the formula YL=0.25*(up1*WP+up2*WY+up3*WS+up4*WN); wherein up1, up2, up3, and up4 are preset proportional coefficients whose values ​​are greater than zero. The larger the value of the print execution monitoring value YL, the more abnormal the current operation of the single-pass printer is, and the less conducive it is to ensuring print quality.

[0064] The print execution monitoring value YL is numerically compared with the preset print execution monitoring threshold. If the print execution monitoring value YL exceeds the preset print execution monitoring threshold, it indicates that the current operating condition of the single-pass printer is abnormal, which is not conducive to ensuring print quality, and a print poor signal is generated; if the print execution monitoring value YL does not exceed the preset print execution monitoring threshold, it indicates that the current operating condition of the single-pass printer is normal, which is conducive to ensuring print quality, and a print good signal is generated.

[0065] At the end of the printing operation of the corresponding print task, the print quality comparison and analysis module collects an image of the print area on the corresponding print object and marks it as a print area image. Based on the print area image and the corresponding standard image, the module uses image recognition technology to judge the print quality and generates a good print quality signal or a bad print quality signal. This module can reasonably analyze and accurately evaluate the printing effect of each print object, which is beneficial for subsequent processing of the print object.

[0066] The print quality error signal is sent to the abnormal warning module. When the abnormal warning module receives the print quality error signal, it issues a corresponding warning and promptly reminds the management staff to strengthen the printing supervision, thereby ensuring the subsequent printing quality and further reducing the management difficulty of the management staff. The specific analysis process of the print quality comparison and analysis module is as follows:

[0067] Based on the printing area image and the corresponding standard image, it is judged whether the printed text and pattern are clear, and the fuzzy ghosting part is identified. If the fuzzy ghosting part exists, the area of ​​the corresponding fuzzy ghosting part is marked as an unqualified surface condition value, and the unqualified surface condition value is numerically compared with a preset unqualified surface condition threshold. If the unqualified surface condition value exceeds the preset unqualified surface condition threshold, the corresponding fuzzy ghosting part is marked as a quality-different part; if the quality-different part exists on the printed object, it indicates that the printing effect of the corresponding printed object is poor, and a print quality-different signal is generated;

[0068] If there are no areas of uneven quality on the printed object, a print quality evaluation value is obtained through print quality normalization analysis. Specifically, the print area image is divided into several square grids using image segmentation technology, and the color difference data of the corresponding square grids are collected. The color difference data of all square grids are averaged to obtain the print color difference detection value, and the proportion of square grids whose color difference data exceeds the preset color difference data threshold is marked as a high color difference proportion value;

[0069] The areas of all fuzzy ghost parts are summed up to obtain a total fuzzy ghost value, and the ratio of the total fuzzy ghost value to the total area of ​​the print area image is calculated to obtain a fuzzy ghost detection value;

[0070] By formula The print color difference detection value HN, the high color difference proportion value HF, and the blur and ghost detection value HW are numerically calculated to obtain a print quality evaluation value HX; wherein sy1, sy2, and sy3 are preset proportional coefficients whose values ​​are greater than zero, and a larger value of the print quality evaluation value HX indicates a worse overall printing effect for the corresponding print object;

[0071] The print quality evaluation value HX is numerically compared with the preset print quality evaluation threshold. If the print quality evaluation value HX exceeds the preset print quality evaluation threshold, it indicates that the printing effect for the corresponding printing object is generally poor, and a print quality error signal is generated; if the print quality evaluation value HX does not exceed the preset print quality evaluation threshold, it indicates that the printing effect for the corresponding printing object is generally good, and a print quality improvement signal is generated.

[0072] Example 2: Figure 2As shown, the difference between this embodiment and the first embodiment is that the abnormality warning module is communicatively connected to the printer quality inspection module. The printer quality inspection module is used to set a detection period. Preferably, the detection period is three hours. The operating status of the single-pass printer during the detection period is comprehensively evaluated, and a quality inspection pass signal or a quality inspection abnormality signal is generated through analysis. When the quality inspection abnormality signal is generated, the abnormality warning module issues an early warning to remind management personnel to inspect and repair the single-pass printer in a timely manner, thereby ensuring the subsequent stable operation of the single-pass printer and improving the printing effect. The degree of intelligence is high. The specific analysis process is as follows:

[0073] The number of times a poor print signal is generated during a detection period is collected and the ratio is calculated with the total printing time of a single-pass printer during the detection period to obtain a poor print detection value, and the number of times a poor print signal is generated during the detection period is collected and the ratio is calculated with the number of print objects that have been printed during the detection period to obtain a poor print detection value;

[0074] The printer quality inspection value ZP is calculated by weighting the poor print quality detection value ZY and the abnormal print quality detection value ZF using the formula ZP = fg1*ZY + fg2*ZF. Here, fg1 and fg2 are preset weight coefficients, and fg2>fg1>0. Furthermore, a larger value of the printer quality inspection value ZP indicates worse overall performance of the single-pass printer during the detection period, and a greater probability that the single-pass printer has an abnormality.

[0075] The printer quality inspection value ZP is numerically compared with the preset printer quality inspection threshold. If the printer quality inspection value ZP exceeds the preset printer quality inspection threshold, it indicates that the operating performance of the single-pass printer during the detection period is generally poor, and the probability of an abnormality in the single-pass printer is high, then a quality inspection abnormality signal is generated; if the printer quality inspection value ZP does not exceed the preset printer quality inspection threshold, it indicates that the operating performance of the single-pass printer during the detection period is generally good, and the probability of an abnormality in the single-pass printer is low, then a quality inspection pass signal is generated.

[0076] Example 3: Figure 3 As shown, the difference between this embodiment and the first and second embodiments is that the present invention proposes a single-pass printer multi-task continuous printing intelligent management method, comprising the following steps:

[0077] Step 1: sorting tasks according to user needs and time sequence, and making the single-pass printer execute all printing tasks according to the task sorting;

[0078] Step 2: Before the printing operation of the corresponding printing task, analyze the adverse factors affecting the printing operation and generate a high-impact printing signal or a low-impact printing signal;

[0079] Step 3: When the low-impact print signal is generated, the single-pass printer is caused to execute the corresponding print task, and the print operation is monitored and its print performance is judged, and a print quality signal or a print quality signal is generated through analysis;

[0080] Step 4: When the printing operation of the corresponding print task is completed, the print quality is judged based on the print area image and the corresponding standard image by image recognition technology, and a good print quality signal or a poor print quality signal is generated accordingly;

[0081] Step 5: When a high-impact printing signal, a poor-quality printing signal, or a poor-quality printing signal is generated, the abnormal warning module issues a warning.

[0082] The present invention also includes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the aforementioned method for intelligent management of multi-task continuous printing for a single-pass printer. Those skilled in the art will appreciate that all or part of the steps in each of the aforementioned method embodiments can be accomplished by hardware associated with the computer program.

Specifically, the memory includes various media capable of storing program code, such as ROM, RAM, a magnetic disk, a USB flash drive, a memory card, or an optical disk.

[0084] Preferably, the processor can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

[0085] The working principle of the present invention is as follows: when in use, all printing tasks are sorted by the multi-task parallel management module, so that the single-pass printer executes all printing tasks according to the task sorting, ensuring that the tasks are completed continuously and efficiently, and before the printing operation of the corresponding printing task, the adverse influencing factors of the printing operation are analyzed by the printing impact analysis module and a high-impact printing signal or a low-impact printing signal is generated. When the low-impact printing signal is generated, the single-pass printer starts the printing operation of the corresponding printing task, and the printing execution monitoring module monitors the printing operation and judges its printing performance. When the printing operation of the corresponding printing task is completed, the printing quality comparison and analysis module uses image recognition technology and judges its printing quality based on the printing area image and the corresponding standard image, thereby realizing effective supervision of the entire process before, during and after printing, significantly reducing the management difficulty of management personnel, and having a high degree of intelligence, which is conducive to realizing large-scale, multi-task printing operations.

Before the printing operation of the corresponding print task, the print impact analysis module analyzes the adverse influencing factors of the printing operation and generates a high-impact print signal or a low-impact print signal; when the low-impact print signal is generated, the single-pass printer performs the printing operation of the corresponding print task, and the print execution monitoring module monitors the printing operation and determines its printing performance, and generates a good print signal or a bad print signal through analysis; When the printing operation of the corresponding print task is completed, the print quality comparison and analysis module collects the image of the print area on the corresponding print object and marks it as the print area image. Based on the image recognition technology and the print area image and the corresponding standard image, the module judges the print quality and generates a good print quality signal or a poor print quality signal. When the abnormal warning module receives a high-impact print signal, a poor print signal or a poor print quality signal, it issues a corresponding warning. The specific analysis process of the print impact analysis module includes: The actual positions of several contour points on the object to be printed are obtained, and the deviation distance of the actual position of the corresponding contour point compared with the corresponding preset standard position is marked as the contour distance measurement value. The contour distance measurement value is numerically compared with the preset contour distance measurement threshold. If the contour distance measurement value exceeds the preset contour distance measurement threshold, the corresponding contour point is marked as an out-of-position contour point; if there is an out-of-position contour point on the object to be printed, a printing high-impact signal is generated; If there are no unplaced contour points on the object to be printed, the contour distance measurements of all contour points are averaged to obtain the in-place accuracy coefficient, and the in-place accuracy coefficient is numerically compared with a preset in-place accuracy coefficient threshold. If the in-place accuracy coefficient exceeds the preset in-place accuracy coefficient threshold, a high-impact printing signal is generated. If the in-place accuracy coefficient does not exceed the preset in-place accuracy coefficient threshold, the ambient temperature and humidity of the single-pass printer environment are collected, and the difference between the ambient temperature and the median of the set standard suitable printing environment temperature range is calculated and the absolute value is taken to obtain the printing environment temperature measurement value. Similarly, the printing environment humidity measurement value is obtained; The dust concentration and wind speed of the environment where the single-pass printer is located are collected and marked as the printing environment gray measurement value and the printing environment wind measurement value respectively. The printing environment comprehensive inspection value is obtained by weighted summing the printing environment temperature measurement value, the printing environment humidity measurement value, the printing environment gray measurement value and the printing environment wind measurement value; And through the analysis of the power supply stability of the printer, a power supply impact comprehensive inspection value is obtained, and the printing environment comprehensive inspection value and the power supply impact comprehensive inspection value are numerically compared with the preset printing environment comprehensive inspection threshold and the preset power supply impact comprehensive inspection threshold respectively. If the printing environment comprehensive inspection value or the power supply impact comprehensive inspection value exceeds the corresponding preset threshold, a high printing impact signal is generated; if both the printing environment comprehensive inspection value and the power supply impact comprehensive inspection value do not exceed the corresponding preset threshold, a low printing impact signal is generated; The specific analysis process of the printer power supply stability analysis is as follows: The current and voltage of a single-pass printer at all times within a unit time are collected, and the variance of all currents within the unit time is calculated to obtain the printer flow wave value. Similarly, the printer pressure wave value is obtained. When the current or voltage is not within the corresponding preset range, the single-pass printer is judged to be in a power stability abnormality state, and the proportion of the time the single-pass printer is in the power stability abnormality state within the unit time is marked as the printer power abnormality value. The power supply impact comprehensive inspection value is obtained by numerically calculating the printer flow wave value, the printer pressure wave value, and the printer power abnormality value. The specific analysis process of the print execution monitoring module includes: The print execution monitoring value is obtained by analysis, and the print execution monitoring value is compared with the preset print execution monitoring threshold value. If the print execution monitoring value exceeds the preset print execution monitoring threshold value, a print poor signal is generated; if the print execution monitoring value does not exceed the preset print execution monitoring threshold value, a print good signal is generated; The analysis and acquisition methods for printing execution monitoring values ​​are as follows: The real-time printing speed of the single-pass printer is collected, and the deviation value of the real-time printing speed compared to the set standard printing speed is marked as a printing speed detection value; the print head of the single-pass printer is monitored to collect inkjet pressure and inkjet flow rate, and the deviation value of the inkjet pressure compared to the set standard inkjet pressure is marked as an inkjet pressure detection value, and the deviation value of the inkjet flow rate compared to the set standard inkjet flow rate is marked as an inkjet volume detection value; and the deviation value of the temperature of the ink to be ejected in the single-pass printer from the set standard ink temperature is marked as an inkjet temperature detection value; and a printing execution monitoring value is obtained by numerically calculating the printing speed detection value, the inkjet pressure detection value, the inkjet volume detection value, and the inkjet temperature detection value; The specific analysis process of the print quality comparison and analysis module is as follows: Based on the printing area image and the corresponding standard image, it is judged whether the printed text and pattern are clear, and the fuzzy ghosting part is identified. If the fuzzy ghosting part exists, the area of ​​the corresponding fuzzy ghosting part is marked as an unqualified surface condition value, and the unqualified surface condition value is compared with a preset unqualified surface condition threshold. If the unqualified surface condition value exceeds the preset unqualified surface condition threshold, the corresponding fuzzy ghosting part is marked as a quality-unusual part; if the quality-unusual part exists on the printed object, a print quality-unusual signal is generated; If there are no quality-defective areas on the printed object, a print quality evaluation value is obtained through print quality normalization analysis, and the print quality evaluation value is numerically compared with a preset print quality evaluation threshold. If the print quality evaluation value exceeds the preset print quality evaluation threshold, a print quality-defective signal is generated; if the print quality evaluation value does not exceed the preset print quality evaluation threshold, a print quality-good signal is generated. The specific analysis process of print quality normalization analysis is as follows: The printing area image is divided into several square grids through image segmentation technology, and the color difference data of the corresponding square grids are collected. The color difference data of all square grids are averaged to obtain the printing color difference detection value, and the proportion of square grids whose color difference data exceeds the preset color difference data threshold is marked as a high color difference proportion value; The areas of all blurred ghosting parts are summed up to obtain the total blurred ghosting value, and the ratio of the total blurred ghosting value to the total area of ​​the printing area image is calculated to obtain the blurred ghosting detection value; the printing quality evaluation value is obtained by numerically calculating the printing color difference detection value, the high color difference occupancy value and the blurred ghosting detection value.
