All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, if not conflicted, the various features of the embodiments of the invention may be combined with each other within the scope of protection of the invention. Additionally, while functional block divisions are performed in apparatus schematics, with logical sequences shown in flowcharts, in some cases, steps shown or described may be performed in sequences other than block divisions in apparatus or flowcharts. The terms "first", "second", "third", and the like used in the present invention do not limit data and execution order, but distinguish the same items or similar items having substantially the same function and action.
The method for generating the print file provided by the embodiment of the present invention is applied to the application scenario shown in fig. 1, where the application scenario 1 includes a user service end 10, a server 20, and at least one printing device (e.g., 31-34 shown in fig. 1). Wherein, the user service end 10 is connected to the server 20 for information interaction, for example, the server 20 is connected by communication in a local area network, a wide area network, a wireless network, a Global System for Mobile communication (GSM), a third generation Mobile communication network, a fourth generation Mobile communication network, a fifth generation Mobile communication network, etc., the user service end may be an electronic device with a communication function, such as a desktop computer, a laptop computer, a tablet computer, etc., the server may be a server, such as a rack server, a blade server, a tower server or a cabinet server, or a server cluster consisting of a plurality of servers, or a cloud computing service center, and the printing device can be any printer with printing function, such as an intelligent digital printer.
It should be noted that the method for generating a print file provided in the embodiment of the present application may be further extended to other suitable application scenarios, and is not limited to the application scenario illustrated in fig. 1. Fig. 1 exemplarily shows the user service terminal 10, the server 20 and the printing device (e.g. 31-34 shown in fig. 1), and in an actual application process, the application scenario may further include more user service terminals, servers and printing devices.
As shown in fig. 2, an embodiment of the present invention provides a method for generating a print file, which is applied to a server, and the method includes:
step S201, receiving and storing the original document file sent by the user service end.
When the original document file needs to be processed, a user sends the original document file for printing to a server through a user service end, and the server stores the original document file after receiving the original document file sent by the user service end. By storing the original document file in the server, the space of printing equipment is not occupied, and meanwhile, the original document file is not required to be transmitted to a production field, so that the original document file can be prevented from being leaked, and the copyright protection is facilitated. In some other embodiments, as shown in fig. 3, before sending the original document to the server, the user service 10 needs to obtain the original document that the client needs to print, where the client may establish communication with the user service through wireless, wired, and usb disk copy, and after establishing connection, the client may send the original document to the user service. When the number of clients needing to print is large, the user service end can receive the printing services of different clients at the same time, for example, the same user service end 10 can receive the original document files sent by the client 1, the client 2, the client 3 and the client 4 at the same time, and send the original document files to the server after receiving the original document files sent by a plurality of users.
In some other examples, in order to distinguish multiple original files, before sending the original files to the server, the user names the original files, for example, if the user ID of the user at the current user service end is three, then one three is added in front of the original file as a prefix, and since the user ID has uniqueness, the original file also has uniqueness.
Step S202, acquiring an image processing task sent by a user service end, processing the original document according to the image processing task, and generating a printing file.
Before printing, the original document file needs to be subjected to image processing, and the original document file is converted into a printing file which can be directly produced by a printing device, for example, the original document file is subjected to raster image processing and converted into a raster or dot matrix file which can be directly printed by the printing device. After sending the original document file to the server, the user service end sends an image processing task to the server, so as to tell the server how to process the original document file, so that the original document file can be directly identified by the printing equipment for production after being processed.
Step S203, storing the printing file, and providing the printing file to the user service end, so that the user service end controls a printing device to perform printing operation according to the printing file.
The method comprises the steps that after a server generates a printing file, the printing file is stored, when the user service end needs to use the printing file, the server sends the printing file to the user service end, and after the user service end receives the printing file, printing operation is carried out on printing equipment which is idle or has few printing tasks according to the printing file.
In some other embodiments, after the server stores the printed document, the server feeds back a storage path to the user service end. And when the user service end needs to use the printing file, searching an access server according to the storage path, acquiring the printing file according to the storage path, and controlling idle printing equipment to perform printing operation according to the printing file.
In some other embodiments, the server includes a storage server, a management server, and a processing server, and when a user needs to perform image processing on an original file, the original file is sent to the storage server through a user service end, and the storage server stores the original file after receiving the original file.
After the storage server stores the original document file, the user needs to process the original document file, so that the user can send an image processing task to the management server through the user service end, wherein the image processing task comprises a first storage path for storing the original document file and image processing parameters. Since each document file is not printed in the same printing format, the user needs to inform the management server of the image processing parameters of this document file when processing the document file.
In some other examples, since different processing servers may process different document files, after receiving the image processing task, the management server may select a corresponding processing server to process the document file according to the image processing parameter and a preset rule. First, after receiving an image processing job, the management server searches all processing servers capable of processing the document file according to the image processing parameters, such as the print size, the rotation angle, and the image color, according to the image processing parameters in the image processing job. When the image processing parameters are image processing parameters requiring specific image colors, the management server selects all processing servers capable of processing the specific image colors according to the specific image colors, and after the processing servers are searched, one of the processing servers is selected according to a preset rule.
In other examples, the processing server may be ranked, with higher rankings being more urgent image processing tasks to be processed. Therefore, when the image processing task is urgent, the corresponding processing server can be matched according to the level of the preset image processing task, so that the urgent task can be processed preferentially without queuing.
After the processing server is selected, the management server sends the image processing parameters and the first storage path of the original document file to the selected processing server, the processing server obtains the original document file from the storage server according to the first storage path of the original document file after receiving the first storage path and the image processing parameters of the original document file, processes the original document file according to the image processing parameters, and generates a printing file after the processing server completes processing on the original document file according to the image processing parameters.
And after the management server generates the printing file, the printing file is sent to a storage server for storage, and after the printing file is stored, the processing server sends feedback information to the management server to tell the management server that the original document file has been successfully processed and a second storage path of the processed printing file is completed. And after receiving the feedback information sent by the processing server and determining that the original document file is processed, the management server sends the second storage path of the printed document file to the user service end. And after receiving a second storage path of the printing file, the user service end acquires the printing file according to the second storage path, and controls idle printing equipment or printing equipment with few printing tasks to perform printing operation according to the printing file when the printing is required.
In other embodiments, the management server needs to detect the progress of the image processing task of the processing server in real time to prevent the processor from failing to delay the printing process due to a failure. And the processing server sends execution feedback information to the management server in real time in the process of processing the image processing task, and after receiving the execution feedback information, the management server judges whether the processing server can process the image processing task or not according to the execution feedback information. For example, if the processing progress of the processing server receiving the execution feedback information is 30% of the processing progress of the current image processing task, and after a period of time, if the processing progress of the received execution feedback information is greater than 30%, the processing server is considered to be able to continue to complete the image processing task, and if the execution feedback information of the processing server or the processing progress of the current processing task is 30%, the processing server is considered to have a fault and is unable to complete the image processing task, and the steps are continuously refreshed for judgment.
When the management server judges that the processing server can not complete the image processing task, the image processing task needs to be redistributed, at the moment, the management server can search the processing server capable of processing the image processing task according to the image processing parameters in the image processing task again according to the image processing parameters, the processing server does not comprise the processing server which is judged that the image processing task can not be completed by the management server, and after reselection, a processing server with a lighter load is selected according to the task load of the selected processing server for processing. If the management server judges that the processing server can complete the image processing task, the image processing task is not redistributed.
In other embodiments, in order to enable the processing server to smoothly process the services when the traffic is large, when the management server determines that the processing server cannot complete the image processing task, the management server indicates that the processing server fails, and the management server sends a fault message to a manager, so that the manager can timely find and maintain the fault of the processing server, and the processing server can normally work to smoothly complete the task.
The embodiment of the invention has the advantages that the original document file is sent to the storage server for storage through the user service end, the original document file can be converted into the printing file which can be identified by the printing equipment after image processing, therefore, after the original document file is stored in the storage server, the user service end sends the image processing task of the original document file to the management server, the image processing task comprises image processing parameters and a first storage path of the original document file, the management server finds all processing servers which can process the image processing task according to the image processing parameters after receiving the image processing parameters and the first storage path of the original document file, then selects one of the processing servers according to preset rules, and sends the image processing task to the selected processing server after selection, to cause the processing server to process the image processing task. And after the processing server finishes the image processing task, the processing server sends the generated printing file to a storage server so that the storage server stores the printing file, and sends a second storage path of the printing file to a management server, and the management server sends the second storage path of the printing file to the user service end after confirming that the processing server finishes the image processing task. When the user needs to print, the user service end acquires the print file according to the second storage path of the received print file, and then controls the printing equipment to print according to the print file. By the mode, the original document file is directly processed by the server and the printed file is generated, so that the printing equipment only needs to perform printing operation according to the printed file, the printing equipment is always in a production state, and the production efficiency is improved. The plurality of printing devices can share the server, and the storage server, the management server and the processing server are coordinated to process the tasks, so that the workload of the printing devices and the preparation time before printing are reduced, the utilization rate of the server is improved, and the cost is reduced. The design manuscript is only stored in the storage server, and can not be directly provided for a production field, so that the problem of copyright disclosure caused by the complexity of production field environment and personnel can be avoided, and the copyright protection is facilitated.
As shown in fig. 4, an embodiment of the present invention further provides a method for generating a print file, which is applied to a user service end, where the method includes:
step S401, sending the original document file to a server, so that the server stores the original document file.
When the original document file needs to be processed, a user sends the original document file for printing to a server through a user service end, and the server stores the original document file after receiving the original document file sent by the user service end. By storing the original document file in the server, the space of printing equipment is not occupied, and meanwhile, the original document file is not required to be transmitted to a production site, so that the original document file can be prevented from being leaked.
Step S402, sending an image processing job to the server, so that the server processes the document file according to the image processing job, and generates a print file.
When printing, the original document file needs to be subjected to image processing first, and the original document file is converted into a printing file that can be directly produced by the printing device, for example, the original document file is converted into a raster or dot matrix file that can be directly printed by the printing device through raster image processing. After sending the original document file to the server, the user service end sends an image processing task to the server, so as to tell the server how to process the original document file, so that the original document file can be directly identified by the printing equipment for production after being processed.
In some other embodiments, the server includes a storage server, a management server, and a processing server, and after the storage server stores the original file, the user needs to process the original file, so the user may send an image processing task to the management server through the user service end, where the image processing task includes a first storage path for storing the original file and an image processing parameter. After receiving the image processing task, the management server searches all the processing servers capable of processing the original document according to the image processing parameters, such as the printing size, the rotation angle, the image color and the like, according to the image processing parameters in the image processing task. When the image processing parameter is that a specific image color is required, the management server searches all processing servers capable of processing the specific image color according to the specific image color. After the processing servers are selected, one of the processing servers is selected according to a preset rule, for example, according to the current task load of the processing server, when the printing traffic is large, more than one image processing task needs to be performed by each processing server, so when the management task allocates the image processing tasks, the processing server with the relatively small load is preferentially selected for processing.
In other examples, the processing server may be ranked, with higher rankings being more urgent image processing tasks to be processed. Therefore, when the image processing task is urgent, the corresponding processing server can be matched according to the level of the preset image processing task, so that the urgent task can be processed preferentially without queuing.
After the processing server is selected, the management server sends the image processing parameters and the first storage path of the original document file to the selected processing server, the processing server obtains the original document file from the storage server according to the first storage path of the original document file after receiving the first storage path and the image processing parameters of the original document file, processes the original document file according to the image processing parameters, and generates a printing file after the processing server completes processing on the original document file according to the image processing parameters.
And step S403, receiving the printing file sent by the server, and controlling the printing equipment to perform printing operation according to the printing file.
The method comprises the steps that after a server generates a printing file, the printing file is stored, when the user service end needs to use the printing file, the server sends the printing file to the user service end, and after the user service end receives the printing file, the user service end controls idle printing equipment or printing equipment with few tasks to perform printing operation according to the printing file.
In some other embodiments, after the processing server generates the print file, the print file is sent to a storage server for storage, and after the print file is stored, the processing server sends a feedback message to a management server to inform the management server that the original document file has been successfully processed and a second storage path of the processed print file is completed. And after receiving the feedback information sent by the processing server and determining that the original document file is processed, the management server sends the second storage path of the printed document file to the user service end. And after receiving a second storage path of the printing file, the user service end acquires the printing file according to the second storage path, and controls idle printing equipment or printing equipment with few tasks to perform printing operation according to the printing file when the printing is required.
The embodiment of the invention has the advantages that the user service end sends the original document file to the storage server, and the storage server stores the original document file after receiving the original document file. And after receiving the image processing task, the management server searches all processing servers capable of processing the image processing task according to the image processing parameters, and then selects one of the processing servers to process the image processing task according to the task load of the processing servers. And after receiving the image processing task, the processing server acquires the original document file according to the first storage path of the original document file, processes the original document file according to the image processing parameters and generates a printing file. The processing server sends the printing file to a storage server for storage, feeds a second storage path of the printing file back to a management server, the management server receives the second storage path and determines that the processing server completes the image processing task, and then sends the second storage path of the printing file to a user service end, and when the user service end needs to print, the user service end obtains the printing file according to the second storage path of the printing file and controls printing equipment to print according to the printing file. By the mode, the original document file is directly processed by the server and the printed file is generated, so that the printing equipment only needs to perform printing operation according to the printed file, the printing equipment is always in a production state, and the production efficiency is improved.

in some other embodiments, after the storage server 110 stores the original document file, the user service 10 sends an image processing task to the management server 120, where the image processing task includes image processing parameters, and after receiving the image processing task, the management server 120 selects the corresponding processing server 130 to process the original document file according to the image processing parameters and preset rules. First, the management server 120, upon receiving an image processing job, searches all the processing servers 130 capable of processing the original document according to the image processing parameters, such as a print size, a rotation angle, and an image color, according to the image processing parameters in the image processing job. When the image processing parameters are image processing parameters requiring a specific image color, the management server 120 selects all processing servers 130 capable of processing the specific image color according to the specific image color, and after the processing servers are searched, selects one of the processing servers 130 according to a preset rule, for example, according to the current task load of the processing server 130, because when the printing traffic is large, more than one image processing task is required to be performed by each processing server 130, the management server 120 preferentially selects the processing server 130 with a relatively small load for processing when distributing the image processing tasks.
In other embodiments, as shown in fig. 6, the processing server 130 includes an image processing task agent module 131 and at least one image processing engine (e.g., 132 in fig. 6), the image processing task further includes a first storage path of the original document file, after the processing server 130 is selected, the management server 120 sends image processing parameters and the first storage path of the original document file to the image processing task agent module 131 of the selected processing server, the image processing task agent module 131 selects an idle or less image processing engine according to the working status of the at least one image processing engine after receiving the first storage path of the original document file and the image processing parameters, after the image processing engine is selected, acquires the original document file from the storage server 110 according to the first storage path of the original document file, and sends the original document file and the image processing parameter to the image processing engine, so that the image processing engine processes the original document file according to the image processing parameter, and generates a print file after the image processing engine of the processing server 130 completes the processing of the original document file according to the image processing parameter. Different image processing engines can execute processing concurrently, so that the processing capacity can be greatly improved, and the efficiency is improved.
In other embodiments, the image processing engine sends the print file to the image processing task agent module 131 after generating the print file, so that the image processing task agent module 131 sends the print file to the storage server 110 for storage. After the print file is stored, the image processing job agent module 131 sends a feedback message to the management server 120, informing the management server 120 that the original file has been successfully processed and the second storage path of the processed print file. After receiving the feedback information sent by the image processing task agent module 131 and determining that the original document file has been processed, the management server 120 sends the second storage path of the print document to the user service terminal 10. After receiving the second storage path of the print file, the user service end 10 acquires the print file according to the second storage path, and when the print file needs to be printed, controls the printing device with idle or few tasks to perform the printing operation according to the print file.
In other embodiments, since the processing server 130 may have a failure or the like when processing the image processing task and cannot complete the image processing task assigned by the management server 120, the management server 120 needs to detect the progress of the image processing task of the processing server 130 in real time, so as to prevent the processor from failing and delaying the printing process. The processing server 130 will send execution feedback information to the management server in real time during the process of processing the image processing task, and after receiving the execution feedback information, the management server 120 determines whether the processing server 130 can process the image processing task according to the execution feedback information. For example, if the processing progress of the processing server 130 receiving the execution feedback information is 30% of the processing progress of the current image processing task, and after a period of time, if the processing progress of the received execution feedback information is greater than 30%, the processing server 130 is considered to be able to continue to complete the image processing task, and if the execution feedback information of the processing server 130 is received or the processing progress of the current processing task is 30%, the processing server 130 is considered to have a fault and be unable to complete the image processing task, and the above steps are continuously refreshed for determination.
When the management server 120 determines that the processing server 130 cannot complete the image processing task, the image processing task needs to be redistributed, at this time, the management server 120 re-searches the processing server 130 capable of processing the image processing task according to the image processing parameters in the image processing task according to the image processing parameters, where the processing server 130 does not include the processing server 130 that the management server 120 determines that the image processing task cannot be completed, and after re-selection, selects one processing server 130 with a lighter load according to the task load of the selected processing server 130 for processing. If the management server 120 determines that the processing server can complete the image processing task, the image processing task is not re-allocated.
In other embodiments, in order to enable the processing server 130 to smoothly process the services when the traffic is large, when the management server 120 determines that the processing server 130 cannot complete the image processing task, it indicates that the processing server 130 fails, and the management server 120 sends a failure message to the manager, so that the manager can timely find and maintain the failure of the processing server 130, and the processing server 130 can normally work to smoothly complete the task.
The embodiment of the present invention has the advantages that the original document file is sent to the storage server 110 by the user service end 10 for storage, and the original document file needs to be converted into a print file that can be identified by the printing device through image processing, so after the original document file is stored in the storage server 110, the user service end 10 sends an image processing task of the original document file to the management server 120, where the image processing task includes an image processing parameter and a first storage path of the original document file, after receiving the image processing parameter and the first storage path of the original document file, the management server 120 finds all processing servers 130 capable of processing the image processing task according to the image processing parameter, then selects one of the processing servers 130 according to a preset rule, after selection, the image processing task is sent to the selected processing server 130 so that the processing server 130 processes the image processing task. After the processing server 130 completes the image processing task, the processing server 130 sends the generated print file to the storage server 110, so that the storage server 110 stores the print file, and sends the second storage path of the print file to the management server 120, and after confirming that the processing server 130 completes the image processing task, the management server 120 sends the second storage path of the print file to the user service terminal 10. When the user needs to print, the user service end 10 obtains the print file according to the second storage path of the received print file, and then controls the printing device to perform the printing operation according to the print file. By the mode, the original document file is directly processed by the server and the printed file is generated, so that the printing equipment only needs to perform printing operation according to the printed file, the printing equipment is always in a production state, and the production efficiency is improved. Here, a plurality of printing apparatuses can share a server, and the storage server 110, the management server 120, and the processing server 130 process tasks in coordination with each other, thereby reducing the workload of the printing apparatuses and the preparation time before printing, improving the utilization rate of the server, and reducing the cost. The design manuscript is only stored in the storage server, and can not be directly provided for a production field, so that the problem of copyright disclosure caused by the complexity of production field environment and personnel can be avoided, and the copyright protection is facilitated.
