Each program relating to file distribution by the file distribution device 10 and the alternative device causes a corresponding processor to determine a distribution destination of a received image file GF on the basis of distribution destination relevant data of the image file GF, and distribution destination relevant/distribution destination association data that associates the distribution destination relevant data with the distribution destination.

Description

  The present invention relates to a file distribution system that distributes an image file generated by reading a document image with a scanner, and more particularly to a file distribution system that performs re-distribution by another device when file distribution fails.

  In the following Patent Document 1, an image file read by a scanner is placed in a shared folder of a file distribution device together with its attribute file (meta information file), and this device stores the contents of the meta information file in the shared folder and the meta information file. A distribution system that determines a distribution destination based on a format of an image file, a character string in a file name, and a file distribution destination determination rule, and distributes the image file to a distribution destination such as a predetermined folder of the own device or another computer. It is disclosed.

  In this system, for example, if the file distribution destination computer is in a sleep state, power-off state or maintenance, or if a connection with this computer cannot be established due to a failure during distribution, The re-distribution process is performed.

  That is, the image file to be distributed is moved into the distribution failure folder, an instance of the interpal timer is generated and the timer is started, and when this time is up, the image file and the meta information file are moved into the shared folder. It is returning.

  According to this system, redistribution can be performed in the same manner as normal distribution processing.

JP 2011-129051 A

  However, redistribution at the time of distribution failure is also performed by the file distribution apparatus, and redistribution processing is performed every time the failure is repeated. Therefore, if the cause of failure is not immediately removed, the redistribution processing increases and normal distribution processing Cause delay.

  In order to solve this problem, the system becomes complex if redistribution at the time of distribution failure is performed by a dedicated file redistribution apparatus. In addition, if the delivery failure is repeated, the re-delivery process increases as described above.

  In view of such problems, it is an object of the present invention to provide a file distribution system capable of performing redistribution with a relatively simple configuration.

  Another object of the present invention is to provide a file distribution system capable of performing redistribution with a relatively simple configuration and suppressing an increase in redistribution processing.

In the first aspect of the file distribution system according to the present invention, an image file read by a scanner is distributed via a file distribution apparatus, and when the distribution fails by the file distribution apparatus, the redistribution is replaced with a file redistribution apparatus. File distribution system,
Each program of the file distribution device and the file redistribution device determines the distribution destination of the image file received by the corresponding processor based on the meta information and the file distribution destination determination rule. The configuration of the part that distributes the image file is the same,
The program of the file redistribution apparatus is configured to, based on the (b) meta information received together with the image file and the file distribution destination determination rule, after a predetermined time has elapsed since the image file was received. The distribution destination is determined, (c) the image file is distributed to the distribution destination, and (d) when distribution of the image file fails, the image file is regarded as newly received and distributed.

  In a second aspect of the file distribution system according to the present invention, in the first aspect, the program of the file distribution apparatus and the file redistribution apparatus is such that the determined distribution destination URI is a document on the Internet. If the URI is a management service URI, the image file is registered in the document management service.

In the third aspect of the file distribution system according to the present invention, in the first or second aspect, the program of the file redistribution device is provided to the processor.
Monitor whether a file has been placed in the receiving folder,
When a file is input, it is determined whether or not a predetermined image file and meta information are included,
If an affirmative determination is made, the current time is read and used as a time stamp, and a set of the time stamp, the identification information of the image file, and the number of times the value is initialized for the first time or its identifier is waited. Add it to the back of the queue as a matrix element,
If the queue element at the head of the queue is NULL or not empty, the queue element is removed from the queue;
The difference between the current time and the time stamp belonging to the retrieved queue element is calculated periodically,
If this difference is greater than or equal to the first set value or a value determined by the first set value and the number of times, it is determined that a predetermined time has elapsed since the image file was received;
The process (a) is executed by
In the process (b), an image file and meta information corresponding to the identification information belonging to the extracted queue element are acquired from the reception folder,
In the process (d), when delivery of the image file fails, the number of times belonging to the extracted queue element is changed in one direction, positive or negative, and this waiting time is only obtained when the number of times is not equal to the second set value. A matrix element is added to the rear end of the queue.

  In a fourth aspect of the present invention, in the third aspect, in the process (a), the value determined by the first set value and the number of times is a product of the first set value and the number of times.

  In the fifth aspect of the present invention, in the third aspect, in the process (a), the value determined by the first set value and the number of times is a product of the first set value and 2 times the power.

  According to the configuration of the first aspect, since the redistribution is replaced by the file redistribution device when the distribution by the file distribution device fails, the load on the file distribution device can be reduced and the software configuration can be simplified. In addition, each program of the file distribution device and the file redistribution device causes the corresponding processor to determine the distribution destination of the received image file based on the meta information and the file distribution destination determination rule, Since the parts that distribute the image file to the distribution destination have the same configuration, the system development cost can be reduced.

  According to the configuration of the second aspect, when the URI of the distribution destination is the URI of the document management service on the Internet, the image file is registered in the document management service, so that various distributions can be mediated. Play.

  According to the configuration of the third aspect, in the file redistribution device, the queue element in the distribution order has the time stamp at the time of reception and the number of times of redistribution, and the current time and the first element extracted from the queue The difference from the time stamp is calculated periodically, and if this difference is greater than or equal to the first set value or the value determined by the first set value and the number of times, a predetermined time has elapsed since the image file was received Since it is not necessary to generate a timer for each delivery failure and perform processing for each failure, the CPU load is reduced. For example, a file redistribution application is installed on the administrator PC to There is an effect that it is possible to also use the distribution apparatus.

  In addition, the number of times the value is initialized for the first time is also included in the queue element, and when the distribution of the image file fails, the number of times belonging to the extracted queue element is changed in one direction, positive or negative, Since the queue element is added to the rear end of the queue only when the number of times is not equal to the second set value, it is possible to repeat redistribution up to a predetermined number of times with a simple configuration.

  According to the configuration of the fourth aspect, in the process (a), the value determined by the first set value and the number of times is a product of the first set value and the number of times. The redistribution interval becomes longer in proportion to the communication path, and it is possible to prevent the redistribution processing load from increasing more than necessary due to a failure in the communication path or the distribution destination. The possibility of installing a distribution application and also serving as a file redistribution device increases.

  According to the configuration of the fifth aspect, in the process (a), the value determined by the first set value and the number of times is a product of the first set value and 2 times the power. Each time the re-delivery interval is doubled, the effect described in the fourth aspect is enhanced.

  FIG. 1 is a schematic explanatory diagram of a file distribution system according to the first embodiment of the present invention.

  A file distribution apparatus 10 that mediates file transmission is coupled to a LAN (local area network) 40 together with an image forming apparatus 20 as a transmission source and N PCs (personal computers) 30-1 to 30-N as distribution destinations. ing. File sharing provided in these OSs for file transmission from the image forming apparatus 20 to the file distribution apparatus 10 and file distribution from the file distribution apparatus 10 to one or more of the PCs 30-1 to 30-N. By using the service, the configuration of the file distribution application is simplified. That is, a shared folder is created in the auxiliary storage device of the file distribution destination, this can be operated by the distribution source, and the file is distributed to the shared folder by distributing the file.

  The distribution destination of the file distribution apparatus 10 is not limited to the PC on the LAN 40, and the distribution is not limited to simple distribution, and the document management service 51 of the cloud 50 on the Internet 42 is distributed (registered) via the router 41. It can also be the first).

  Regarding the tagging for retrieval to a document, since the operability of the PC is better than that of the image forming apparatus 20, first, an image file read by the image forming apparatus 20 is converted into an electronic document via the file distribution apparatus 10 and a document management service. 51 is registered. At this time, the document management service 51 automatically associates the registration date and time with the document. Thereafter, the user designates the registration date and time range from the PC to the document management service 51, reads the document, designates the document, and associates a tag with the document, thereby enabling easy and appropriate search. .

  FIG. 2 is a schematic hardware block diagram related to file transmission between the file delivery apparatus 10 and the PC 30-i. The PC 30-i is one of the PCs 31 to 30-N in FIG.

  In the file distribution apparatus 10, the CPU 11 is coupled to the PROM 13, DRAM 14, hard disk drive 15, and network interface 16 via the interface 12. In FIG. 2, a plurality of types of interfaces are represented by one block 12 for simplification.

  The PROM 13 is a flash memory, for example, and stores a BIOS. The DRAM 14 is used as a main storage device. The hard disk drive 15 stores a virtual storage OS, various drivers, and a file distribution application. The network interface 16 is coupled to the network LAN 40.

  The PC 30-i includes components 31 to 37, and the components 31 to 36 correspond to the components 11 to 16 of the file distribution apparatus 10, respectively. The interactive input / output device 37 includes, for example, a keyboard, a pointing device, and a display device. The hard disk drive 35 stores an application and a scanner driver that scan an original image and process the image to generate an image file. In the case of the administrator PC 30-1, file redistribution software is further stored in the hard disk drive 35.

  FIG. 3 is a functional block diagram of the file distribution apparatus 10. Each functional block operates in cooperation with computer hardware and software. FIG. 4 is a sequence diagram of a process in which a user U operates the image forming apparatus 20 to scan a document image to generate a scanned image and automatically distribute the file to the PC 30-i via the file distribution apparatus 10. It is.

  The configuration and operation of FIG. 3 will be described below with reference to the sequence of FIG. The following parentheses are step identification codes of the sequence in FIG.

  (S1) The user U operates the operation panel of the image forming apparatus 20 or inputs a user ID and password to the image forming apparatus 20 by using an IC card and logs in. The scan / distribution function or the document management service is operated on the operation panel. The document registration function to 51 (ScanToDocManager) is selected, conditions such as color / monochrome mode, resolution, and image file format in image reading are selected, and a scan start button is pressed.

  (S2) In response to this, the image forming apparatus 20 scans the document image under the selected condition, and generates the image file GF on the memory of the image forming apparatus 20 or in the auxiliary storage device.

  When ScanToDocManager is selected in step S1, this function name “ScanToDocManager” is added to the name of the scanned image file GF.

  (S3) Next, the image forming apparatus 20 relates to this image file, and includes a user identifier input at the time of login and an identifier (source identifier) of the image forming apparatus 20, for example, a model and a set of serial numbers. An information file MF is generated.

  (S4) Next, the image forming apparatus 20 transmits (injects) the scan image file GF and the meta information file MF into the reception folder 70 which is a shared folder in the file distribution apparatus 10 by using the file sharing service of the OS. . Thus, the scanned image file 71 and the meta information file 72 are stored in the reception folder 70. In order to simplify the configuration, the scan image file GF and the meta information file MF have the same file name main body portion and are linked to each other, and only the file name extensions are different from each other. The image file and the meta information file may be archived and sent as one file.

  Here, as shown in FIG. 5, the in-folder monitoring unit 73 includes a queue management unit 74 and a queue 75.

  (S5) The queue management unit 74 monitors whether or not a file has been input into the reception folder 70 via the event notification function included in the service software operating in the background of the OS. If this is detected, it is determined from these extensions whether the scan image file GF and the meta information file MF are a pair. If the determination is affirmative, the main body portion FNm having the name of the scanned image file GF is added to the rear end of the queue 75 as a queue element 75e. In FIG. 5, the queue 75 holds elements 75e having values FNm to FN0, with FNm positioned at the rear end and FN0 positioned at the head.

  Here, as illustrated in FIG. 6, the delivery destination determination processing unit 76 includes a file format detection unit image file format detection unit 77, a meta information extraction unit 78, and a delivery destination determination unit 79.

  (S6) If the element 75e exists in the queue 75 in FIG. 5, that is, if the head element 75e is not NULL, the image file format detection unit 77 extracts this element 75e and performs the following processing.

  That is, the file format detection unit image file format detection unit 77 finds out the files in the reception folder 70 whose file name main body matches FN0, of which the extension is “pdf” or “jpg”, A file that matches one of the predetermined image file extensions such as “png” and “bmp” is found, and this is used as the format identifier of the scanned image file.

  (S7) Next, the meta information extraction unit 78 extracts the user identifier and the transmission source identifier from the meta information file whose file name main body matches FN0 and whose extension is “meta” among the files in the reception folder 70.

  (S8) Next, the delivery destination determination unit 79 includes the file name body part FN0, the meta information including the image file format, the user identifier, and the transmission source identifier, and the file delivery destination determination rule 80 as shown in FIG. The delivery destination URI is determined, and control is transferred to the delivery unit 81. Since the file delivery destination determination rule 80 has a hierarchical structure, it can be constituted by an XML file, for example.

  The file delivery destination determination rule 80 in FIG. 7 indicates that the delivery destination is determined by a combination of a user identifier (user ID), a transmission source identifier, a character string included in the file, and an image file format identifier (file extension). Yes. A blank indicates that it is optional, and in the case of the same user identifier, the priority is higher in the upper row, the meta information is collated in order from the upper row, and the delivery destination of the first matching row is applied.

  The first line of the file distribution destination determination rule 80 is to distribute to the distribution destination A regardless of the user ID, the transmission source identifier, and the image file format if “ScanToDocManager” is included in the file name body. Is shown.

  In the present embodiment, the distribution destination A in FIG. 7 is the URI of the document management service 51, and the distribution destinations B to I are all the paths of the folder 61 or the folder 62 shown in FIG. It is assumed that the URI of the shared folder outside the apparatus 10 is, for example, A = “SMB: //192.168.126.162/SCAN/Deliberation.jpeg/”, E = “c: / Design”.

  (S9) The distribution unit 81 moves the scanned image file 71 to the determined distribution destination via the OS file system in accordance with the URI of the distribution destination, distributes it using the SMB protocol, or sends it to the document management service 51. Perform the registration process. In this specification, “movement” and “registration” are both forms of distribution.

  FIG. 8 is a schematic flowchart showing document registration processing when the distribution destination for one element 75e is the document management service 51. In the following, the step identification codes in FIG. 8 are shown in parentheses.

  (S10) The file delivery apparatus 10 issues a registration request to the document management service 51 using the SOAP / HTTP protocol.

  (S11) If there is no response to this request yet, the process proceeds to step S12, and if present, the process proceeds to step S13.

  (S12) If the set time, for example, 30 seconds has not elapsed since the request start in step S10, the process returns to step S11. If it has elapsed, that is, for example, the file distribution destination PC 31 is in a sleep state or a power off state If the connection with the document management service 51 cannot be established within the set time due to a failure or a failure in the middle of distribution, the process proceeds to step S15.

  (S13) The document management service 51 requests the file distribution apparatus 10 for the user ID and password. In response to this, the file distribution apparatus 10 refers to a table (not shown), reads out the user ID and password for the document management service 51 corresponding to the user ID input by the image forming apparatus 20, and stores them in the document. Transmit to the management service 51. If the authentication is passed, the process proceeds to step S14.

  (S14, S15) By registering the scanned image file GF in the document management service 51 in accordance with a predetermined protocol, the document registration process for the element 75e is completed. However, if the above reason occurs during the registration process and the connection with the document management service 51 is cut off, the process proceeds to step S16.

  (S16) The distribution unit 81 transmits the scanned image file 71 and the meta information file 72 to the administrator PC 30-1, and ends the distribution process related to the element 75e.

  Next, file redistribution in the administrator PC 30-1 will be described.

  The reason why the file redistribution application is installed in the administrator PC 30-1 without including an independent file redistribution device is that the redistribution processing usually hardly occurs and the burden on the processor as described later is reduced. This is because the file redistribution application is configured.

  FIG. 9 is a functional block diagram of a file redistribution function unit 60R configured by a file redistribution application and hardware installed in the administrator PC 30-1.

  The file redistribution function unit 60R adds a transmission delay unit 90 to the file distribution function unit 60 of FIG. 3, slightly changes the configuration of the in-folder monitoring unit 73 of FIG. The redistribution destination is in the reception folder 70R, that is, a configuration having many common parts with the file distribution function unit 60, thereby reducing the development cost of the entire system. The distribution destination determination processing unit 76R, the file distribution destination determination rule 80R, and the distribution unit 81R of the file redistribution function unit 60R are respectively the distribution destination determination processing unit 76, the file distribution destination determination rule 80, and the distribution of the file distribution function unit 60 of FIG. The configuration is the same as that of the unit 81.

  FIG. 10 is a functional block diagram showing the configuration of the in-folder monitoring unit 73R and the transmission delay unit 90.

  Similarly to the queue management unit 74 in FIG. 5, the queue management unit 74R monitors whether or not files have been input into the reception folder 70R. From the name, it is determined whether or not it is a set of the scanned image file GF and the meta information file MF. If an affirmative determination is made, the current time is read from the clock unit 91 of the transmission delay unit 90 to obtain a time stamp TSm, and a set of this TSm, the body portion FNm of the name of the scanned image file GF, and the number of times Nm is waited for. It is added to the rear end of the queue 75 as a matrix element. Here, the number Nm is the number of distributions of the same target in the file redistribution function unit 60R, and the initial value is 1.

  In the transmission delay unit 90, the difference calculation unit 92 extracts the element 75Re from the queue 75R and substitutes the value into the variable 920 if the head element 75Re of the queue 75R is not NULL (or empty), and the time stamp TS0. And the difference between the current time indicated by the clock unit 91 and the time stamp TS0 is periodically calculated. If this difference is greater than or equal to the set value 94, the comparison unit 93 causes the distribution destination determination processing unit 76R of FIG. 9 to be executed.

  The delivery destination determination processing unit 76R reads the contents of the variable 920 and determines the delivery destination based on the file name main body part FN0 in the same manner as the delivery destination determination processing unit 76 described above. The distribution unit 81R distributes the image file to this distribution destination in the same manner as the distribution unit described above. When the delivery fails, the delivery unit 81R notifies the queue management unit 74R of the failure.

  In response to this, the queue management unit 74R increments the number N0 of the variable 920 by 1, and if the number N0 is equal to or less than the set value M, the contents of the variable 920 are substituted for the new element 75Re. It is added to the rear end of the queue 75R. As a result, redistribution is repeated up to M times at the time interval of the set value 94.

  According to the first embodiment, when the file distribution apparatus 10 fails to distribute, the redistribution is replaced by the administrator PC 30-1 having the file redistribution function, so that the load on the file distribution apparatus 10 is reduced. In addition, the software configuration can be simplified, and each program related to file distribution of the file distribution apparatus 10 and the administrator PC 30-1 receives the image file GF received for the corresponding processor, its meta information, and the file distribution destination. Based on the determination rule 80, the distribution destinations are determined, and the configuration of the parts for distributing the image file GF to the distribution destinations is the same, so that the system development cost can be reduced.

  Further, when the URI of the distribution destination is the URI of the document management service on the Internet, the image file GF is registered in the document management service 51, so that this system has an effect that various distributions can be mediated.

  Further, in the file redistribution apparatus 10, the time stamp TSm at the time of reception and the number Nm of redistributions are given to the elements of the distribution order queue 75R, and the current time and the time stamp TS0 of the first element extracted from the queue 75 are provided. If the difference is equal to or greater than the set value 94, it is determined that a predetermined time has elapsed since the image file GF was received, and a timer is generated for each delivery failure and processed for each. Since the CPU load is reduced, it is possible to install the file redistribution application on the administrator PC 30-1 and also use the file redistribution apparatus.

  Further, the number Nm of values initialized for the first time is also included in the queue element, and when the delivery of the image file GF fails, the number N0 of the extracted queue element 75Re is incremented by 1, and the number of times is Since this queue element is added to the rear end of the queue 75R only when it is not equal to the set value, there is an effect that redistribution can be repeated a predetermined number of times with a simple configuration.

  FIG. 11 is a functional block diagram illustrating configurations of the in-folder monitoring unit 73R and the transmission delay unit 90A according to the second embodiment of the present invention.

  In the second embodiment, the transmission delay unit 90 in FIG. 10 is obtained by inserting a multiplication unit 95 between the comparison unit 93 and the set value 94 as the transmission delay unit 90A. The multiplier 95 outputs a value obtained by multiplying the set value 94 by the number of times N0 in the variable 920. If the difference obtained by the difference calculation unit 92 is equal to or greater than this value, the comparison unit 93 causes the distribution destination determination processing unit 76R in FIG. 9 to be executed.

  The other points are the same as in the first embodiment.

  According to the second embodiment, since the redistribution interval becomes longer in proportion to the number of redistribution N0, it is possible to prevent the redistribution processing load from increasing more than necessary due to a failure in the communication path or the distribution destination. Therefore, the possibility that the file redistribution application is installed in the administrator PC 30-1 or the like and also serves as a file redistribution apparatus increases.

Note that the multiplication unit 95 may output a value obtained by multiplying the set value 94 by the value 2 ^N0 . In this case, the redistribution interval is twice the previous interval, and the effect is enhanced.

  In the first and second embodiments, the administrator PC 30-1 has a file redistribution function. Therefore, when a failure occurs in the administrator PC 30-1 or the LAN 40, redistribution to the document management service 51 is performed. If this is not possible and the failure continues, redistribution will fail during that time.

  FIG. 12 is a schematic explanatory diagram of a file delivery system according to the third embodiment of the present invention for solving this problem.

  In the third embodiment, the same file redistribution function in the administrator PC 30-1 of the second embodiment is provided as a file redistribution service 53 to the cloud 52 on the Internet 42. Then, only for redistribution to the document management service 51, the file redistribution service 53 sends the scanned image file GF and meta information file MF to be redistributed from the file distribution apparatus 10 to the file redistribution service 53. Redistribution to the management service 51 is performed.

  The other points are the same as in the first embodiment.

  In the above, preferred embodiments of the present invention have been described. However, the present invention includes various modifications, and other configurations that realize the functions of the respective components described in the above embodiments are used. However, other configurations that would be conceived by those skilled in the art from these configurations or functions are also included in the present invention.

  For example, the meta information may be information associated with the distribution destination, and includes information including the distribution source user ID and the document type, only information embedded in the image file GF, or only the file name of the image file GF. Also good.

  The queue element may be a set of values as described above or an identifier (pointer) thereof.

  Furthermore, the initial value of the redistribution count Nm may be set to 10, for example, and may be configured to decrement by 1 each time redistribution is repeated, and stop the redistribution when the count Nm reaches the set value 0 is there.
