Description

[0001] Document type conversion system and providing method [

The present invention relates to a document type conversion system and a method for providing the same. More particularly, the present invention relates to a document type conversion system capable of quickly converting a large number of document files by performing a job of converting a file type of a digital document in parallel, and a method of providing the same.

In order to open and view a digital document created through a specific document creation program (word processor) in a terminal device such as a computer, a document creation program used to create the digital document in the terminal device, a viewer for viewing the digital document, The application needs to be installed. However, not all users have installed a specific document creating program or viewer on their terminal device. Users who use a terminal device that does not have a document creating program or a viewer installed on the terminal You may not be able to view the document. Of course, such a user may install a document creating program used to create the digital document or a document viewer capable of viewing the digital document in his / her terminal device, but inconvenience may arise in the installation of the program, A lot of time can be wasted looking for.

Therefore, in the case of a digital document to distribute and transmit a digital document to another person, the file type of the digital document is converted into a type that is easy to browse, and then distributed and delivered. In many cases, a PDF developed by Adobe Systems (Portable Document Format, movable document format).

PDF has been developed for the same purpose regardless of computer environment, and has device independence and resolution independence. No proprietary technology was used in the document format or production technology. And the document format is open to support PDF in various commercial and free programs. The advantage of being able to express most documents, difficult to modulate contents through encryption and compression techniques, to give various licenses, and to be supported by various programs can be compared with other document formats.

In addition, in order to prevent the edited digital document from being edited, the digital document may be converted into an image type such as JPG or TIFF and distributed.

There are various techniques for changing the file type, but there is a method of using a file printer (virtual printer) which outputs the file of the target type as a representative. Generally, a printer generally refers to a device that prints a document or an image created by a document creation program of a computer on a print sheet. However, a file printer is software that outputs a digital document in a file of a specific type instead of printing it on paper. Most file printers have a user interface or application programming interface (API) that is very similar to that of a real printer, so users can convert the type of digital document in the same way that a printer prints a digital document You can work.

1 is a diagram for explaining an operation of converting a digital document using a file printer.

In order to change the A.doc file created by Microsoft Word program (MS Word) to PDF type, the user first has to use a reader application (document creation program or viewer application; 1) that can read .doc file in MS Word format A.doc (3) is read (S10). Thereafter, an output menu may be selected in the reader application, and a print device to be output may be selected as the PDF file printer 2 and an output request for A.doc may be made to the file printer 2 (S20). Then, the file printer 2 can output the PDF file A.pdf (4).

The file type conversion method described above may cause problems when a plurality of reader applications simultaneously output a digital document. Referring to FIG.

Most file printers, like regular printers, have a spooling function. Spool (Simultaneous Peripheral Operation On-Li) is a technique designed to reduce waiting time caused by slow processing speed of peripheral devices compared to central processing unit by allowing central processing unit and input / output unit to operate independently in a computer system , And the spooler is a program that manages spooling, such as queuing jobs and pulling them out one at a time. Most operating systems include a printer spooler, and some applications have their own print spooler.

2 shows a case in which the reader applications 1 to 3 (1-1 to 1-3) sequentially write A.doc (3-1), B.txt (3-2), C, jpg (3-3) It indicates the case of converting to PDF type through a file printer.

In this manner, when a plurality of applications request output to a file printer at the same time, the requested print jobs are sequentially input to the job queue by the spooler described above, and the file printer 2 sequentially executes file conversion operations To convert A.doc to A.pdf (4-1), B.txt (3-2) to B.pdf (4-2), C.jpg (3-3) to C .pdf (4-3).

However, in the case of an actual printer, the work should be performed serially (that is, in order) using a work queue, but a file printer output in the form of a file. There is no problem even if it is processed. If the file printer stops operating due to an error in any one of the print jobs due to such a characteristic, all the subsequent print jobs contained in the job queue may not be processed. For example, if a printing error occurs during the output operation of B.txt in FIG. 2, the output operation of C.jpg can not proceed.

Referring to FIG. 3, a document type conversion system 100 may be provided to implement a document type conversion system providing method according to an embodiment of the present invention. The document type conversion system 100 converts the file types of the plurality of original digital documents 300-1 to 300-N to generate corresponding target digital documents 310-1 to 310-N .

Here, the file type refers to a special way of encoding digital information into a computer file, and may also be referred to as a file format. The file type is generally identified through a file extension. Depending on the operating system, the file type may be classified through external metadata such as metadata (e.g., file header, magic number) or MIME type in the file .

In one embodiment, the document type conversion system 100 may be implemented and included in a given computing system 10, as shown in FIG. In this case, all or a part of the document type conversion system 100 may be implemented as predetermined conversion software driven by the computing terminal 10.

In yet another embodiment, the document type conversion system 100 may be implemented as a separate physical device from the computing system 10, as shown in FIG.

4 is a block diagram illustrating a configuration of a document type conversion system according to an embodiment of the present invention. 4, the document type conversion system 100 includes an account creation module 110, a login module 120, a logout module 130, a control module 140, a process removal module 150, And a command input module 160. According to an embodiment of the present invention, some of the above-described components may not necessarily correspond to components necessary for implementation of the present invention, Of course, may include more components.

The document type conversion system 100 may include hardware resources and / or software required to implement the technical idea of the present invention, and it is understood that the document type conversion system 100 necessarily means one physical component or one device It is not. That is, the document type conversion system 100 may mean a logical combination of hardware and / or software provided to implement the technical idea of the present invention. If necessary, May be implemented as a set of logical structures for implementing the technical idea of the present invention. In addition, the document type conversion system 100 may mean a set of configurations separately implemented for each function or role for implementing the technical idea of the present invention. For example, the account creation module 110, the login module 120, the logout module 130, the control module 140, the process removal module 150, and / or the command input module 160 may be connected to different physical devices Or may be located in the same physical device. Also, depending on the implementation, the account creation module 110, the login module 120, the logout module 130, the control module 140, the process removal module 150, and / or the command input module 160 Each of the modules may also be located in a different physical device, and configurations located in different physical devices may be organically coupled to each other to realize the functions performed by the respective modules.

In this specification, a module may mean a functional and structural combination of hardware for carrying out the technical idea of the present invention and software for driving the hardware. For example, the module may mean a logical unit of a predetermined code and a hardware resource for executing the predetermined code, and it does not necessarily mean a physically connected code or a kind of hardware. Can be easily deduced to the average expert in the field of < / RTI >

The control module 140 may include other components included in the document type conversion system 100 according to an embodiment of the present invention such as the account creation module 110, the login module 120, the logout module 130, The process removal module 150 and / or the command input module 160, etc.).

The login module 120 may log in to an operating system installed in the computing system 10 with a plurality of different user accounts to generate a plurality of process operating environments corresponding to the plurality of user accounts.

3, the login module 120 can log into the operating system of the computing system 10 with the USER 1 account and create the process execution environment 200-1. The process execution environment 200-2 can be created by logging into the operating system of the computing system 10, , And log into the operating system of the computing system 10 with the USER N account to create the process execution environment 200-N. Such a login process to a plurality of user accounts can be performed in parallel. At this time, each of the process drive environments 200-1 to 200-N may be identified by a user account. FIG. 3 shows an example of a file type conversion operation using a file printer. In this case, each of the process operating environments 200-1 to 200-N is a file printer 220-1 to 220-N .

The file printers 220-1 to 220-N may be virtual printers that output the input information as a digital document of a specific file type, and the output file types may be different from each other.

If the login module 120 fails to log in using a specific user account, the user account that fails to log in through the account creation module 110 may be created and then logged in again.

Meanwhile, the login module 120 may try to log in using pre-stored user accounts, but may generate a user account name according to a predetermined naming rule and log in using the created user account. For example, when the login module 120 needs to log in with ten user accounts, the login module 120 generates ten account information by attaching different serial numbers to a predetermined string, Can be used to log in.

Meanwhile, the control module 140 can be executed in a process driven environment in which a predetermined conversion process is generated each time a user account is logged into the operating system and a corresponding process operating environment is created.

The conversion process may perform an operation of converting a predetermined original document to generate a target document having a predetermined conversion file type. The conversion process may convert a plurality of original documents in turn. In this case, the conversion process may receive a list of original documents to be converted from the control module 140. [ On the other hand, the types of original documents may be different from each other.

In one embodiment, the manner in which the conversion process changes the file type may vary. For example, the conversion process may include a predetermined rule list for changing a file type, and the conversion process parses an original document to extract an element constituting the original document, and then, using the rule list, The type of the original document may be converted by converting each element of the document into an element of the target document corresponding thereto.

In another exemplary embodiment, a file printer for generating a file of the converted file type may be separately included in a process-driven environment in which the conversion process is executed. In this case, And outputting the document to generate the destination document.

In addition, the conversion process may convert the type of the original document using a predetermined reader application that can read the document corresponding to the original file type. That is, the conversion process loads a predetermined reader application capable of reading a document corresponding to the original file type, the loaded reader application reads the original document, drives the file printer, It is possible to control the destination document to be generated by transmitting it to the printer.

Also, according to an embodiment, the conversion process may call a reader application that can read the digital document of such file type after verifying the file type of the original document to be converted. For example, the conversion process may be divided through file extensions, but depending on the embodiment, internal metadata (file header, magic number) or external metadata (Mac OS type code, UTI of Mac OS X, OS / Attribute, POSIX extension property, MIME type, file format identifier (FFID), file content based format authentication).

On the other hand, the file types of a plurality of original documents to be converted may be different from each other, and the file types of generated destination documents may also be different from each other. For example, the conversion process may alternatively select a reader application depending on the type of the original digital document, and may alternatively select a file printer depending on the type of destination document.

Meanwhile, the control module 140 may perform a file type conversion operation of an original document without a separate conversion process generated in each process operation environment. For example, the control module 140 outputs a predetermined original document to a file printer included in the corresponding process operating environment whenever a new process work environment is created by login to a specific user account, You can create a destination document of the file type. For example, the control module 140 may generate a thread corresponding to the specific user account, and the generated thread may execute a reader application in a process running environment corresponding to the specific user account, This original document can be controlled to be output to a file via a file printer.

The document type conversion system 100 according to the above-described embodiment may be useful especially when a plurality of reader applications share one file printer. In the past, when a plurality of reader applications request output to a file printer, they are sequentially stacked in a job queue and serialized. Therefore, not only is the speed very slow, but also the remaining conversion jobs are not processed There was a problem that I could not do. However, the document type conversion system 100 according to an embodiment of the present invention uses a reader application capable of reading an original document to be converted and a file printer capable of outputting as a file type of a target document The type conversion of a large number of digital documents can be performed in parallel through a plurality of file printers while easily converting file types, thereby providing a technical idea capable of solving the conventional problems.

On the other hand, among a specific reader application, there may be a process of requesting input of a user in a series of processes from loading an original document file to outputting through a file printer, and stopping the operation until input of a user is made. This application can cause problems in batch operations where multiple original documents must be converted in order. In order to solve such a problem, the command input module 160 detects that an input UI requesting a user's input command is outputted from the reader application, and can input a predetermined command to the input UI instead of the user.

Meanwhile, the process removal module 150 may remove all the processes created under a predetermined target user account name.

As described above, the document type conversion system 100 according to an embodiment of the present invention can create a process drive environment for each of a plurality of user accounts and perform a file type conversion operation therein. Therefore, if a conversion process executed in a process-driven environment corresponding to a specific user account is stopped due to an error of a file printer or a reader application, the process removal module 150 is executed in the process- You can remove the process. At this time, since each process operating environment is independent of each other, processes in other process operating environments can continue to operate without being affected.

According to an embodiment, the process removal module 150 obtains the producer information of all the processes executed in the computing system 10 to remove a process operating in a process-driven environment corresponding to a specific target user account, It is possible to remove the process when the process creator is the target user account as compared with the target user account to be removed.

Meanwhile, when the file type conversion operation is completed in the process operating environment corresponding to the specific user account, the logout module 130 logs out the user account from the operating system and releases the system resources allocated to the process operating environment .

5 is a flowchart illustrating an operation method of a document type conversion system according to an embodiment of the present invention.

The document type conversion system 100 may perform the following operations for a plurality of user accounts U _i (1 <= i <= N). Work on each user account can be done in parallel.

First, the document-type conversion system 100 may log in to the account U _i to the operating system installed on a given computing system (S100).

If the login is successful, a process operating environment corresponding to U _i may be created (S 110). For example, if the login is successful when the operating system is Windows operating system sessions, windows stations and acquires the desktop that authorizes the user U _i access and set your account profile and environment variable process-driven environment E _i Lt; / RTI &gt; At this time, the process driving environment may include a file printer P _i .

Thereafter, the document type of the original document can be converted through the reader application that can read the original document and the file printer P _i included in the process driving environment E _i , which is executed in the process driving environment E _i (S 120)

When the conversion operation is completed, the document type conversion system 100 logs out the U _i (S 130) and releases the resources allocated to the process driving environment E _i (S 140).

On the other hand, according to an embodiment, the document type conversion system 100 may include a processor and a memory for storing a program executed by the processor. The processor may include a single-core CPU or a multi-core CPU. The memory may include high speed random access memory and may include non-volatile memory such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid state memory devices. Access to the memory by the processor and other components can be controlled by the memory controller. Here, when the program is executed by a processor, the program may cause the document type conversion system 100 according to the present embodiment to perform the method of providing the document type conversion system described above. For example, when the program is executed by the processor, the program causes the document type conversion system to log in to the operating system with a user account that has not yet logged in to an operating system installed in a predetermined computing system, Generating a conversion process that operates in the process-driven environment, and converting the predetermined original document through the generated conversion process to generate a target document having a predetermined conversion file type And to perform a document type conversion system providing method.

Meanwhile, the method for providing a document type conversion system according to an exemplary embodiment of the present invention may be implemented in the form of computer-readable program instructions and stored in a computer-readable recording medium. The target program may also be stored in a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Program instructions to be recorded on a recording medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of software.

Examples of the computer-readable recording medium include magnetic media such as a hard disk, a floppy disk and a magnetic tape, optical media such as CD-ROM and DVD, a floptical disk, And hardware devices that are specially configured to store and execute program instructions such as magneto-optical media and ROM, RAM, flash memory, and the like.
