In existing printing systems, usually only simple single document printing can be performed. For batch printing tasks that need to process a large amount of different content, it is often necessary to manually enter the content and adjust the format one by one, which is inefficient and prone to errors. At the same time, there is a lack of effective means for data verification and quality monitoring during the printing process, making it difficult to ensure the accuracy and stability of the printing tasks. Therefore, it is of great practical significance to develop a printing system that can efficiently process batch printing tasks and has complete data verification and monitoring functions.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0016] like Figure 1-1 As shown in FIG. 1 , the present invention provides a batch printing system integrated with OCR recognition, which comprises: A task generation module is used to generate a printing task and generate a plurality of different areas to be entered after obtaining a printing template based on the printing task; A control module, the control module includes: a task control module, a synchronization control module, a monitoring module and an information recording module, the control module is configured to: form a corresponding relationship between the data entered by the control sub-units and the information input module for multiple different areas to be recorded; form synchronization control for different areas to be recorded through a logic chain; and generate a monitoring module for monitoring the changes in the characteristics of the areas to be recorded caused by the changes in the characteristic values ​​when the task control module executes the printing task according to the synchronization control between the control sub-units; The control subunit is used to execute the printing tasks of different areas to be recorded in the printing tasks, and feed back the characteristic values ​​of the corresponding areas to be recorded when the characteristics change during the printing process to the information recording module for recording, and verify the printing information input in the printing task and the recorded information; The information recording module is used to store printing information when executing a printing task; The monitoring module is based on whether a feature value of one of the to-be-recorded areas changes from a first feature to a second feature with a feature value of a non-recorded area near the to-be-recorded area, and if so, records the amount of change of the feature value in the non-recorded area with the feature change using a reference coordinate system as a reference; The verification module verifies the printing information and record information input in the printing task, and determines whether the change in the characteristic value in the non-input area meets the preset tolerance threshold.

[0017] like Figure 1 As shown, a batch printing system with integrated OCR recognition is used. For example, in the field of vocational skills training, institutions need to print completion certificates for a large number of trainees after each training session. In the past, manually filling in certificate information is not only inefficient, but also prone to errors in information such as name, training subjects, and grades. By using a batch printing system with integrated OCR recognition, various information of trainees is organized into data files and transmitted to the batch printing system, wherein the task generation module generates printing tasks based on the certificate template, and quickly creates a waiting-for-entry area containing information such as the trainee's name, ID number, training course, grades, and completion date; wherein the control module starts working, and the task control module executes the printing task in order according to the preset instructions; wherein the synchronization control module accurately associates each waiting-for-entry area with the input data to ensure one-to-one correspondence of the information, for example, the information in the trainee's name and grade area can be accurately matched when printing.

[0018] Specifically, during the printing process, the control subunit is responsible for the printing tasks of each area to be recorded. Once there are situations such as blurred fonts and color deviations that may cause changes in the characteristics of the area to be recorded, the characteristic values ​​will be fed back to the information recording module to facilitate the subsequent verification of the printed information to ensure that the information is accurate. At the same time, each printed content is re-entered for comparison and confirmation with the original entered data.

[0019] Specifically, the monitoring module is responsible for real-time monitoring. If the characteristic value of the key information area on the certificate changes abnormally, such as the text in the name column suddenly becomes thicker or changes color, the monitoring module will quickly determine whether the characteristic value of the surrounding non-entry area has also changed, and record the change amount of the characteristic value of the abnormality through the reference coordinate system. In actual application, the reference coordinate system is established according to the overall layout of the printing template and the position of the key area; for example, a two-dimensional reference coordinate system is determined with the upper left corner of the certificate as the coordinate origin, the horizontal right as the positive direction of the X axis, and the vertical downward as the positive direction of the Y axis; the reference coordinate system covers the entire printing area, including the area to be entered and the non-entry area. For example, in the certificate printing scenario, when the key information area (area to be entered) changes abnormally, if the characteristic value of the surrounding non-entry area also changes accordingly, the pre-set reference coordinate system is used to determine the location of the abnormality, and the change amount of the characteristic value at that location (such as the degree of font thickness change, the value of color change, etc.) is recorded at the same time, and data support is provided for the subsequent inspection module to determine whether the change amount meets the preset tolerance threshold.

[0020] Among them, the inspection module will re-check the printing information and record information to determine whether the change in the characteristic value of the non-input area is within the preset tolerance threshold, so that in the process of executing the printing task, it can be ensured that each printed content can meet the preset tolerance requirements (width requirements and the size of the characters accommodated in the unit area).

[0021] In this application, with the help of the batch printing system, printing tasks can be executed in batches, and the printing of all completion certificates can be completed in a short time, and the error rate is greatly reduced, which greatly improves work efficiency and the accuracy of certificate production.

[0022] Specifically, the task generation module includes: a feature acquisition module and a configuration module, wherein the feature acquisition module acquires the unprinted printing template during printing based on the printing task, and extracts multiple areas to be printed based on the features of the unprinted printing template. Among them, the feature acquisition module uses image recognition and data analysis technology to parse the template based on the unprinted template obtained by scanning, for example, to identify the location of key information such as the student's name, ID number, training course name, grades, and completion date on the certificate, and divide these locations into different areas to be printed, for example, the rectangular area where the student's name is located is determined as one area to be printed, and the area where the ID number is located is determined as another area to be printed, etc.

[0023] Specifically, the configuration module has several configuration units, each of which corresponds to a region to be printed. The configuration unit is used to configure the printing task of the corresponding region to be printed, and forms a link with different control subunits based on the corresponding relationship to configure the printing task to each different region to be printed. According to the characteristics and requirements of each region to be printed, each configuration unit inside it starts to work, and each configuration unit corresponds to a region to be printed one by one. Taking the student name region as an example, the corresponding configuration unit will set the font to Kaiti, the font size to No. 3, the color to black, and the center alignment and other format parameters. For the score region, the configuration unit can set a specific digital format and retain one decimal place. After the configuration unit completes the parameter configuration, it forms a link with different control subunits based on this corresponding relationship; for example, the control subunit responsible for printing the student name region will receive the printing task parameters passed by the configuration unit, including font, font size, color, alignment, and student name data to be printed; the control subunit accurately executes the printing task of the student name region according to these parameters.

[0024] In some embodiments, it also includes: a scanning module and a content recognition module, wherein the scanning module is used to scan the unprinted printing template and the printing template in the printing task, and the content recognition module is used to extract features based on optical character recognition and / or image feature recognition. Among them, after obtaining the unprinted printing template, the feature acquisition module first fully analyzes the template, and uses optical character recognition (OCR) technology and image analysis algorithms to identify the text, graphics, tables and other elements in the template. Before printing, the scanning module fully scans the unprinted certificate template and converts the image information of the template into a digital signal. The content recognition module uses optical character recognition and image feature recognition technology to extract features from the scanned template, and further confirms the accuracy of the area to be printed, such as identifying the font style, position coordinates and other information of the name area to ensure consistency with the preset template.

[0025] Specifically, during the printing process, the scanning module continues to work and performs real-time scanning of the print template in the printing task. The information recording module records various types of information in the printing process in detail, including abnormal conditions reported by the scanning module and the content recognition module. At the same time, once printing abnormalities are found during printing, such as blurred text, color deviation, etc., the monitoring module will immediately capture the changes in the feature values ​​of the area to be entered, and the content recognition module will perform feature extraction again to analyze the image features of the abnormal area.

[0026] In some embodiments, it also includes: a user interaction module and an information input module, wherein the user interaction module provides an operation interface for the generated printing template, and adjusts the positional relationship of multiple areas to be printed of the printing template based on the printing task; the user interaction module can manually fill the printing template into the task generation module; the information input module is used to input multiple groups of printing information corresponding to multiple areas to be printed.

[0027] Specifically, the user interaction module provides an intuitive operation interface for the generated certificate printing template, which is convenient for staff to operate; for example, staff can use this interface to adjust the positional relationship of each area to be printed according to actual needs; if the certificate design has changed, the original name was in the upper left corner, and now needs to be adjusted to the upper right corner, the operation can be easily completed in the user interaction module; at the same time, the user interaction module also allows staff to manually fill in the printing template into the task generation module; if individual student information is missing in the system, staff can directly enter it manually in the interactive interface, and transmit it to the task generation module after completion to ensure the smooth progress of the printing task.

[0028] Specifically, the information input module is used to input multiple sets of printing information corresponding to multiple areas to be printed; the training institution imports the sorted student information data into the information input module, and the information input module will accurately match the student's name, ID number, training course, grades, completion date and other information to the corresponding areas to be printed.

[0029] Specifically, the synchronization control of different areas to be entered through logical chains is as follows: the synchronization control module has several logical chains, and each logical chain connects the control subunits of two related areas to be printed. Among them, several logical chains of the synchronization control module connect the control subunits of the related areas to be printed; taking the two areas to be printed, the student's name and the score, as an example, a logical chain connects the control subunit responsible for printing the student's name with the control subunit responsible for printing the score; in this way, when printing the student's name, the control subunit of the score area associated with it will also be prepared synchronously; during the printing process, the printing rhythm and data matching of the two can be effectively guaranteed, ensuring that the student's name and the corresponding score are accurately presented on the certificate; for another example, the two areas of graduation date and training course are also synchronized through logical chains; the control subunit responsible for printing the graduation date is connected to the control subunit responsible for printing the training course, so that when printing the graduation date, the printing of the training course can also be coordinated with it, ensuring the consistency and accuracy of the two key information on the certificate.

[0030] Specifically, the monitoring module has a setting unit, and a link is formed between different to-be-printed areas and control subunits corresponding to the unprinted template. The monitoring module builds a monitoring path when its characteristics change according to the mutually related control subunits, so as to monitor the change in the characteristic value of the to-be-printed area. Among them, the setting unit in the monitoring module forms a link between different to-be-printed areas and control subunits corresponding to the unprinted template; for example, the control subunit of the student's name area is mutually related to the control subunit of the score area, and the setting unit will establish a link between the two control subunits; based on these mutually related control subunits, the monitoring module builds a monitoring path when the characteristics change; when printing the student's name, the monitoring module follows this monitoring path and pays attention to the characteristic value change of the score area associated with it; once the characteristic value of the student's name area, such as the font, changes suddenly, the monitoring module will immediately follow the monitoring path to check whether the characteristic value of the score area also changes abnormally; in this way, the monitoring module can monitor the change in the characteristic value of the to-be-printed area in real time.

[0031] The present invention can quickly generate and process multiple printing tasks through the collaborative work of the task generation module and the control module, reduce manual intervention, and improve printing efficiency; it can also effectively ensure the accuracy of printing information and reduce the occurrence of erroneous printing through the verification function of the control subunit and the information recording module and the judgment of the inspection module; it can also monitor the changes of characteristic values ​​in the printing process in real time through the monitoring module, promptly discover possible problems, and ensure the stability of printing quality.

[0032] The present invention also provides a batch printing method integrated with OCR recognition, characterized in that: the batch printing system integrated with OCR recognition as described in any of the preceding items is adopted, comprising the following steps: S1: Create a printing task, generate a printing template and extract the area to be printed based on the printing task, and correspond each configuration unit in the configuration module to a region to be printed; S2: Import printing information, and operate and adjust the printing template; S3: The task control module executes the printing task, and the logic chain of the synchronization control module connects the control subunits of the associated areas to be printed to achieve synchronous control of the printing tasks of the related areas; S4: During the execution of the printing task, the characteristic value of the printed template is monitored, and information of each printed content is recorded and verified.

[0033] Specifically, after the system receives a batch task to print certificates, the feature acquisition module obtains the unprinted certificate template; uses OCR technology and image analysis algorithms to parse the certificate template, identify the text, graphics and other elements therein, and extracts multiple areas to be printed based on the position, attributes and logical relationships of the elements, such as the student's name, ID number, training course, grades, completion date and other areas.

[0034] Specifically, each configuration unit in the configuration module corresponds to an area to be printed; according to the design requirements and actual needs of the certificate, the configuration unit sets printing parameters for the corresponding area to be printed, such as font, font size, color, alignment, etc.; the configuration unit forms a link with different control sub-units based on the corresponding relationship, and passes the configured printing task to the control sub-unit.

[0035] Specifically, the user operates the generated certificate printing template through the operation interface provided by the user interaction module; the positional relationship of multiple areas to be printed can be adjusted according to actual conditions to meet personalized design requirements; if some templates are missing in the system, the user can also manually fill in the printing template to the task generation module.

[0036] Specifically, the information input module receives student information data imported by the user, which includes multiple sets of printing information corresponding to multiple areas to be printed, such as student name, ID number, training course, grades, completion date, etc.; the information input module accurately matches this information to the corresponding area to be printed.

[0037] Specifically, the logical chain of the synchronous control module connects the control subunits of the associated areas to be printed; for example, the control subunit responsible for printing the student's name is connected to the control subunit responsible for printing the grades, thereby realizing synchronous control of the printing tasks in the related areas and ensuring data matching and printing rhythm coordination.

[0038] Specifically, the scanning module scans the unprinted certificate template before printing, and performs real-time scanning of the template in the printing task during the printing process; the content recognition module extracts features based on the scanning results using OCR and image feature recognition technology; the setting unit in the monitoring module constructs a monitoring path when the feature changes according to the link relationship between the different to-be-printed areas corresponding to the unprinted template and the control sub-unit; the monitoring module monitors the change in the feature value of the to-be-printed area in real time along the monitoring path, and records any changes in the feature value, such as font blur, color deviation, etc., immediately.

[0039] Specifically, the information recording module stores the printing information when executing the printing task, as well as the characteristic value change information fed back by the monitoring module; the control subunit continuously verifies the printing information and the recording information during the printing process to ensure the accuracy of the printed content.

[0040] Specifically, in S4, the inspection module verifies the printing information and record information input in the printing task according to a preset tolerance threshold, and determines whether the change in the characteristic value in the non-input area meets the requirements; if the threshold requirements are met, the printing task is deemed normal and a qualified certificate is output; if not, an alarm is issued to prompt the staff to adjust or check the printing task.

[0041] In the present invention, multiple functional modules are used to work together to realize the full process automation from template acquisition, information input to printing task execution and quality monitoring, thereby improving the efficiency and accuracy of certificate printing.
