Description

Technical Field

[0001] The present invention relates to the technical field of printing management, and 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 the printing task when the print head or print medium passes through the printing area once during the printing process. In the packaging industry, marking, coding and pattern printing of cartons, cardboards, wood boards and other products are important links in the production process, and single-pass printers are often used to achieve printing operations;

[0003] A Chinese invention patent with publication number CN116991341A discloses an intelligent printing equipment management system and method based on the Internet of Things, which can adaptively adjust the order of file printing, effectively reducing the phenomenon that users cannot print files in time when emergencies occur. However, it is difficult to effectively monitor and control the entire process before, during and after printing in actual use, and managers cannot quickly make 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] A single-pass printer multi-task continuous printing intelligent management system includes a multi-task parallel management module, a printing impact analysis module, a printing execution monitoring module, a printing quality comparison analysis module and an abnormal warning module; the multi-task parallel management module receives all printing tasks from a user terminal, and 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 printing high impact signal or a printing low impact signal, and sends the printing high impact signal to the abnormal warning module;

[0009] When a print low impact signal is generated, the single-pass printer starts the printing operation of the corresponding print task, and the print execution monitoring module monitors the printing operation and determines its printing performance, generates a print good table signal or a print bad table signal through analysis, and sends the print bad table signal to the abnormal warning module;

[0010] When the printing operation of the corresponding printing task is completed, the printing 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, and judges its printing quality through image recognition technology based on the printing area image and the corresponding standard image, thereby generating a good printing quality signal or a poor printing quality signal, and sending the poor printing quality signal to the abnormal warning module; the abnormal warning module issues a corresponding warning when receiving a high-impact printing signal, a poor-quality printing signal or a poor-quality printing 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, and the contour distance measurement value is numerically compared with the preset contour distance measurement threshold value. If the contour distance measurement value exceeds the preset contour distance measurement threshold value, 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 in-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 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 where 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, and the printing environment humidity measurement value is obtained in the same way;

[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, and 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's 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, and 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 rate, 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 sprayed in the single-pass printer and 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 numerically compared with the 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 there is a quality-different part on the printed object, a print quality-different signal is generated;

[0025] If there are no quality-differentiated parts 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-differentiated 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 the print quality normalization analysis is as follows:

[0027] The printing area image is divided into several square grids by image segmentation technology, 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 the number 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 blurred ghosting detection value is obtained by calculating the ratio of the total blurred ghosting value to the total area of ​​the printing area image; 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 abnormal warning module is communicatively connected to the printer quality inspection module, and the printer quality inspection module is used to set a detection period, comprehensively evaluate the operation status of the single-pass printer during the detection period, generate a quality inspection qualified signal or a quality inspection abnormal signal through analysis, and make the abnormal warning module issue an early warning when the quality inspection abnormal signal is generated; the specific analysis process is as follows:

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

[0031] The printer quality inspection value is obtained by weighted summing up 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 intelligent management of 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, analyzing the adverse factors affecting the printing operation and generating a high-impact printing signal or a low-impact printing signal;

[0035] Step 3: when the printing low impact signal is generated, the single-pass printer is made to execute the corresponding printing task, and the printing operation is monitored and its printing performance is judged, and a printing good table signal or a printing bad table signal is generated through analysis;

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

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

[0038] Furthermore, the present invention proposes a computer storage medium on which a computer program is stored, and when the program is executed by a processor, a method for intelligently managing multi-task continuous printing of a single-pass printer is implemented.

[0039] Furthermore, the present invention proposes a computer device, including 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 printing tasks are sorted by a multi-task parallel management module to ensure that the tasks are completed continuously and efficiently, and the adverse factors affecting the printing operation are analyzed before the printing operation of the corresponding printing task. When a printing low-impact signal is generated, the single-pass printer starts the printing operation of the corresponding printing task and judges its printing performance in real time, and judges its printing quality when the printing operation of the corresponding printing task ends, so as to realize effective supervision of the whole process before, during and after printing, significantly reduce the management difficulty of the management personnel, and facilitate the realization of large-scale, multi-task printing operations;

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0048] Embodiment 1: Figure 1 As shown, the present invention proposes a single-pass printer multi-task continuous printing intelligent management system, including 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 abnormal warning module;

[0049] The multi-task parallel management module receives all printing tasks from the user terminal, 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 printing task, the printing impact analysis module analyzes the adverse factors affecting the printing operation and generates a printing high impact signal or a printing low impact signal, and sends the printing high impact signal to the abnormal warning module. When the abnormal warning module receives the printing high impact signal, it issues a corresponding warning to remind the management personnel not to perform the printing operation temporarily, and take corresponding control measures in time, so as to reduce the degree of adverse impact on the printing quality and reduce the management difficulty of the management personnel; the specific analysis process of the printing 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, and the contour distance measurement value is numerically compared with the preset contour distance measurement threshold value. If the contour distance measurement value exceeds the preset contour distance measurement threshold value, 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 contour points that are not in place on the object to be printed, indicating that the position accuracy of the object to be printed is low, a high printing impact 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 in-place accuracy coefficient threshold, it indicates that the position accuracy of the object to be printed is low, and a printing high impact signal is generated.

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

[0056] The printing environment comprehensive inspection value Gs is obtained by weighted summing the printing environment temperature measurement value Gy, the printing environment humidity measurement value Gp, the printing environment gray measurement value Ge and the printing environment wind measurement value Gf through the formula Gs=(b1*Gy+b2*Gp+b3*Ge+b4*Gf) / 4; wherein b1, b2, b3 and b4 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the printing environment comprehensive inspection value Gs is, the worse the printing environment condition is, and the greater the adverse effect on the printing quality is;

[0057] The current and voltage of the 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 the variance of all voltages within a unit time is calculated to obtain the printer pressure wave value; and the current and voltage are numerically compared with the corresponding preset ranges, and when the current or voltage is not within the corresponding preset range, it is determined that the single-pass printer is 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 a unit time is marked as the 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 the power supply impact comprehensive inspection value Lg; wherein rw1, rw2 and rw3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the power supply impact comprehensive inspection value Lg is, the worse the power supply condition for the single-pass printer is, and the greater the adverse effect on the printing quality is;

[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, indicating that the degree of adverse impact on the printing quality is generally large, then a high printing impact signal is generated; if both the printing environment comprehensive inspection value Gs and the power supply impact comprehensive inspection value Lg do not exceed the corresponding preset threshold, indicating that the degree of adverse impact on the printing quality is generally small, then a low printing impact signal is generated.

[0060] When the printing low-impact 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 printing operation and judges its printing performance. It generates a print quality signal or a print quality signal through analysis, and sends the print quality signal to the abnormal warning module. When the abnormal warning module receives the print quality signal, it issues a corresponding warning to remind the management personnel to investigate the cause and take corresponding improvement measures, thereby ensuring the stable and efficient printing operation and improving the printing 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 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 rate, 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 rate compared with the set standard inkjet flow rate 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 and the set standard ink temperature is marked as the 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 through the formula YL=0.25*(up1*WP+up2*WY+up3*WS+up4*WN); wherein up1, up2, up3 and up4 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the print execution monitoring value YL is, the more abnormal the current operation status of the single-pass printer is, and the less conducive it is to ensure the printing 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] When the printing operation of the corresponding printing task is finished, the printing 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, and judges its printing quality based on the printing area image and the corresponding standard image through image recognition technology, and generates a good printing quality signal or a bad printing quality signal accordingly, which can reasonably analyze and accurately evaluate the printing effect of each printing object, which is conducive to the subsequent processing of the printing object;

[0066] The print quality difference signal is sent to the abnormal warning module. When the abnormal warning module receives the print quality difference signal, it issues a corresponding warning to remind the management personnel to strengthen the printing supervision in time, so as to ensure the subsequent printing quality and further reduce the management difficulty of the management personnel. 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 the 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 for the corresponding printed object is poor, and a print quality-different signal is generated;

[0068] If there is no quality difference on the printed object, the print quality evaluation value is obtained through print quality normalization analysis, specifically: the print area image is divided into a number of square grids through image segmentation technology, 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 the number 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 ghosting parts are summed up to obtain a total fuzzy ghosting value, and the total fuzzy ghosting value is ratio-calculated to the total area of ​​the printing area image to obtain a fuzzy ghosting detection value;

[0070] By formula The print color difference detection value HN, the high color difference occupancy value HF and the blur 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 the larger the value of the print quality evaluation value HX, the worse the printing effect of the corresponding print object is overall;

[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] Embodiment 2: Figure 2As shown, the difference between this embodiment and the first embodiment is that the abnormal warning module is communicatively connected to the printer quality inspection module, and the printer quality inspection module is used to set a detection period. Preferably, the detection period is three hours; the operation status of the single-pass printer in the detection period is comprehensively evaluated, and a quality inspection qualified signal or a quality inspection abnormal signal is generated through analysis, and when the quality inspection abnormal signal is generated, the abnormal warning module issues an early warning to remind the management personnel to check and repair the single-pass printer in time, so as to ensure the subsequent stable operation of the single-pass printer and improve the printing effect, and the intelligent degree is high; the specific analysis process is as follows:

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

[0074] The printer quality inspection value ZP is obtained by weighting and summing the print quality inspection value ZY and the print quality inspection value ZF through the formula ZP=fg1*ZY+fg2*ZF; wherein fg1 and fg2 are preset weight coefficients, and fg2>fg1>0; and the larger the value of the printer quality inspection value ZP, the worse the overall performance of the single-pass printer during the detection period, and the greater the 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 relatively 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 relatively low, then a quality inspection qualified signal is generated.

[0076] Embodiment 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, analyzing the adverse factors affecting the printing operation and generating a high-impact printing signal or a low-impact printing signal;

[0079] Step 3: when the printing low impact signal is generated, the single-pass printer is made to execute the corresponding printing task, and the printing operation is monitored and its printing performance is judged, and a printing good table signal or a printing bad table signal is generated through analysis;

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

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

[0082] The present invention also includes a readable storage medium on which a computer program is stored.

[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 printing impact analysis module analyzes the adverse factors affecting the printing operation and generates a high-impact signal or a low-impact signal. When the low-impact 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, having a high degree of intelligence, and being conducive to realizing large-scale, multi-task printing operations.
