Description

  The present invention relates to a network device, a network device control method, and a program thereof.

  In recent years, with respect to setting values of information processing apparatuses such as multifunction peripherals (network devices), the master data may be stored in another information processing apparatus such as a management server management server connected to the network for centralized management. These values are synchronized. When the value of the master data on the management server management server is changed, the changed value is notified to the multifunction device, and the setting value in the multifunction device is also changed. Similarly, when the setting value in the multifunction device is changed, the setting value of the master data on the management server management server is also changed. Some setting values are synchronized between multiple MFPs. When the setting value is changed, the master data on the server and the setting values in all MFPs to be synchronized The value is changed.

  Possible when the user changes the setting value from the multifunction device to preserve the setting value in case of failure of the multifunction device or to prevent mixing of values when synchronizing values with multiple multifunction devices It is necessary to transmit the setting value change to the management server management server as quickly as possible. At this time, if communication to the management server management server is performed as an extension of the setting value change operation by the user, the user is restricted for a long time until the communication is completed, such as when the management server management server is physically located far away. Doing so may cause disadvantages. Therefore, Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for reducing the waiting time of the user by responding to the process before all of the processes requested by the user are completed and accepting another job.

JP 2002-84387 A

  However, in Patent Document 1, the user can use the processing product after all the actual processing has been performed. For this reason, some setting values change the operation of the MFP itself, and therefore it is necessary to reflect the change of the setting values in the MFP independently of the communication processing to the management server. For example, if the setting value related to the entire printing function of the multifunction device is changed, communication with the management server takes a long time, and if the setting value change of the multifunction device itself is not reflected until the end of this communication, the setting change is made for printing during this period There is a risk that the contents of the above will not be reflected and the user will be disadvantaged.

  The present invention has been made in view of the above problems, and when a request for changing a setting value is received from a user or the like, the changed setting value can be used and can be quickly transmitted regardless of the communication state with the management server. An object of the present invention is to provide a network device that synchronizes the set values.

  In order to solve the above-described problem, a network device according to the present invention is a network device that communicates with a management server that manages master data of setting values to be set in a plurality of network devices, and that instructs to change the setting values. Receiving means for receiving, storage means for storing the job generated for changing the set value in the storage means, and management of the network device in response to successful storage of the job in the storage means An execution unit that executes a change of a setting value according to the stored job with respect to the database to be stored, and a setting value according to the stored job when the job is stored in the storage unit Request means for making a request for reflecting the change in the master data, and the change of the set value by the execution means is completed. Depending on the fact, without waiting for a response from the management server based on the request, and having a notification means for notifying the completion of change of the set value.

  According to the present invention, when a network device receives a request for changing a setting value, the changed setting value can be used, and the setting value can be quickly synchronized regardless of the communication state with the management server. A device can be provided.

When there is a change in the master data, the change information is notified to the MFP 120a and the MFP 120b via the network 100. When the setting value change information is received from the multifunction device 120a or the multifunction device 120b, the master data value is changed.

  The multifunction device 120 is a device (network device) that realizes a plurality of types of functions (copy, FAX, etc.), and stores therein setting values used when executing these functions. When the setting value is changed, the change information is notified to the management server 110 via the network 100. Further, when the change information of the master data of the setting value is received from the management server 110, the value of its own setting value is changed. Depending on the set value, values may be synchronized between a plurality of multifunction devices such as the multifunction device 120a and the multifunction device 120b.

  When the setting value is changed in the master data on the management server 110, the setting value change information is notified to both the MFP 120a and the MFP 120b. When the setting value of either the multifunction device 120a or the multifunction device 120b is changed, the management server 110 is notified of the change information first, and then the management server 110 sends the change information to the other multifunction device via the network 100.

  FIG. 3 is a block diagram illustrating the configuration of the multifunction peripheral 120 according to the present embodiment. The multifunction machine 120 includes a controller unit 300, an operation unit 320, a scanner 330, and a printer 340. The controller unit 300 is connected to an operation unit 320 and is also connected to a scanner 330 as an image input device and a printer 340 as an image output device.

  The controller unit 300 includes a CPU 302, and the CPU 302 starts up the OS by a boot program stored in the ROM 306. The CPU 302 executes application programs stored in the HDD 305 and executes various processes on the OS. A RAM 303 is used as a work area for the CPU 302. The RAM 303 provides a work area and an image memory area for temporarily storing image data. The HDD 305 stores the application program, image data, and various setting values. A setting value management method in the multi function peripheral 120 will be described later.

  An operation unit I / F 301, a device I / F 304, a network 307, and an image processing unit 308 are connected to the CPU 302 via the system bus 310, as well as the ROM 306 and the RAM 303.

  FIG. 4 is a block diagram illustrating a configuration of master data managed by the management server 110 according to the present embodiment. The master data 401 includes a setting value information DB 410, a common setting value DB 411, a device management DB 412, an individual setting value DB 413, and a configuration information management DB 414.

  FIG. 5A is a diagram showing data stored in the setting value information DB 410. The setting value information DB 410 is a database that stores metadata regarding each setting value managed by the management server 110. In the setting value information DB 410, there are a wording to be presented to the user, a key identifier for identifying the setting value when communicating with the multifunction device 120, an initial value, a value range, an applicable model / version, and a display condition for the setting value. Stored.

  Each setting value managed by the setting value information DB 410 may have a different setting value range or initial value, such as whether or not the setting value exists, depending on the model of the MFP 120 and the firmware version. In FIG. 5A, the setting value represented by the key identifier “settings.pattern” is present in all individuals in the models A and B, but in the model C, the firmware version is 3.01. It indicates that it exists only in subsequent individuals. In addition, the setting value whose key identifier is represented by “settings.density” indicates that in the model B, the range of the setting value and the initial value differ depending on the version of the installed firmware.

  FIG. 5B is a diagram illustrating data stored in the common setting value DB 411. The common setting value DB 411 is a database that manages setting value values that are commonly used by all of the plurality of MFPs 102 that manage setting values by the management server 110. The common setting value DB 411 stores a key identifier and a value corresponding to the identifier. In the present embodiment, this key identifier is an identifier having the same system as the key identifier of the setting value information DB 410.

  FIG. 5C shows data stored in the individual setting value DB 413. The individual setting value DB 413 is a database that manages setting values having different values in each of the plurality of multifunction peripherals 102 that manage setting values by the management server 110. It is assumed that a plurality of individual setting value DBs 413 exist corresponding to the individual MFPs. The individual setting value DB 413 stores a key identifier and a value corresponding to the identifier. This key identifier is an identifier having the same system as the key identifier of the setting value information DB 410.

  FIG. 5D is a diagram showing the contents of device configuration information for each multifunction device managed by the configuration information management DB 414. The configuration information management DB 414 is a database that stores and manages a plurality of device configuration information. This device configuration information includes an individual identifier for identifying the individual MFP 120, a model name, a firmware version, license information indicating available functions, and the like. The model name, firmware version, license, and the like have the same system as that stored in the setting value information DB 410.

  The device management DB 412 is a database for managing individual identifiers of the MFPs 120 whose setting values are managed by the management server 110. The management server 110 uses each database of the master data 401 described above to set different setting values for each of the managed multifunction devices 120, setting values common to all the managed multifunction devices, and the setting values themselves. It is possible to collectively manage metadata.

  FIG. 6 is a diagram illustrating an example of the configuration of the setting value DB 601 stored in the HDD 305 of the multifunction peripheral 120 according to the present embodiment. The setting value DB 601 is a database that stores setting values used in the multifunction machine 120. The setting value stored in the setting value DB 601 is composed of elements such as a key identifier for identifying the setting value, a value of the setting value, a UI display word, an initial value, a value range, and a display condition. These elements are managed in the same system as that managed by the master data 401. When the setting value is changed in the management server 110 or the multifunction device 120, the setting value is synchronized by communicating at least the key identifier and the value in the data shown in FIG.

  FIG. 7A is a flowchart illustrating an example of processing executed by the multifunction device 120 when the user of the multifunction device 120 changes the setting value. This processing is executed by the CPU 302 of the multi function peripheral 120 reading out a program from the HDD 305, developing it in the RAM 303, and executing it. First, upon receiving a setting value change instruction from the user, the multi-function peripheral 120 displays a setting value editing screen on the operation unit 320, and accepts a setting value change content from the user (step S701).

  Here, FIG. 8 is a diagram illustrating an example of a setting value editing screen displayed on the operation unit 320 by the multi function peripheral 120 in step S701. FIG. 8 shows a screen for setting whether to enable the copy-forgery-inhibited pattern function during printing. When the user presses the “OK” button after selecting the “valid” or “invalid” button, the CPU 302 determines the value after the setting change from the content operated by the operation unit 320.

  Returning to FIG. 7A, the MFP 120 generates the contents of the setting values designated by the user as a job so that the setting contents changed at any subsequent timing can be referred to. And store (save) (step S702). Specifically, the key identifier of the setting value whose setting has been changed and the changed value are stored as a set in a predetermined area of the HDD 305 as a file. This job is used when a request is made to change the master data 401 of the management server 110 later. Details of this request processing will be described later. In addition, if there is other necessary information such as the date and time when the setting change was accepted, the identifier of the user who changed the setting, etc., they may be stored in the job at the same time.

  Next, the multi function peripheral 120 determines whether or not the job can be stored without any problem in step S702 (step S703). If the job has been successfully saved (YES), the multi function peripheral 120 rewrites the contents of the setting value DB 601 stored in the HDD 305 in accordance with the contents of this job (step S704). In the multifunction machine 120, the changed setting value can be used by the user. Finally, the multifunction machine 120 updates the display of the operation unit 320 to an appropriate screen (step S705) and ends the process. That is, the user is notified of the completion of the setting value change.

  On the other hand, if it is determined in step S703 that the job has not been successfully saved (failed) (NO), the process proceeds to step S705. In step S <b> 705, the MFP 120 cannot later transmit the changed content to the management server 110, and thus updates the screen without rewriting the setting value DB 601 stored in the HDD 305, and ends the process. As a result, for example, even when a job cannot be saved due to an insufficient area in the HDD 305, the setting value DB 601 managed by the multifunction device 120 and the contents of the master data 401 managed by the management server can be kept synchronized. It becomes.

  FIG. 7B is a flowchart showing processing for requesting the management server 110 to change the master data 401 in accordance with the contents of the job stored in step S702 of FIG. In this process, it is assumed that the CPU 302 of the multi-function peripheral 120 reads out a program from the HDD 305, develops it in the RAM 303, and executes it asynchronously and simultaneously with the process shown in FIG.

  After starting the processing, the multifunction device 120 loops the following processing while the job can be processed. Note that whether or not the job can be processed may be arbitrarily determined. For example, by determining that the job cannot be processed during the start-up or termination processing of the multifunction device 120, It is possible to shorten the processing time for starting and ending. Next, the multifunction device 120 determines whether a file corresponding to the job is stored in a predetermined area of the HDD 305 (step S710). This process corresponds to the process of saving the change contents of the setting value as a job in step S702.

  If a job exists in step S710 (YES), the contents of the job are read, and the management server 110 is requested to change the master data 401 together with the changed key identifier and value (step S711). Here, as a method of requesting a change to the management server, for example, it is conceivable to notify the change contents by HTTP (Hypertext Transfer Protocol). It doesn't matter.

  Next, the multi function peripheral 120 determines whether or not the request processing performed in step S711 has succeeded (step S712). The specific determination method may be determined from, for example, whether or not the server can be connected or the response content of the server, but any other determination method may be used. If it is determined in step S712 that the request process is successful (YES), the multi function peripheral 120 deletes the file corresponding to the requested job (step S713) and returns to the top of the loop.

  On the other hand, if it is determined that the request processing in step S712 is not successful (failed) (NO), the process returns to the top of the loop without deleting the file corresponding to the job, and the job request is retried again. Here, the process of step S711 is performed asynchronously and simultaneously with the process of FIG. Therefore, even if communication with the management server is delayed due to network congestion or the like, the process of responding to the user is not delayed in step S705, and the waiting time of the user does not change.

  In the process shown in FIG. 7B, in step S710, it is determined whether there is a file in a predetermined area of the HDD 305. However, the present invention is not limited to this, and other methods are adopted. Also good. Conventionally, for example, a method is conceivable in which all of the set value DB 601 is searched at a constant period to extract a portion different from the master data 401 and notify the management server 110 of the extracted portion. However, in this method, it is necessary to search the set value DB 601 at a constant cycle and collate with the master data 401 regardless of whether or not the set value has been rewritten, which may reduce the processing efficiency.

  Compared with this, in the method according to the present embodiment, it is not necessary to search or collate a database for determining whether or not there is a job, so that the processing efficiency can be improved. Note that job information is not necessarily stored as a file in the HDD 305, and may be a predetermined area of the RAM 303, for example. In this case, a predetermined area of the RAM 303 is confirmed in step S710.

  In addition, depending on the OS executed on the CPU 302, when the job is successfully stored in step S703, a signal or the like is generated to notify the processing of FIG. 7B that the job has been stored. Therefore, if the start of step S711 is triggered by this signal generation, asynchronous processing can be performed without periodically checking the contents of the folder.

  In the present embodiment, the case where the user of the multifunction device 120 changes the setting value has been described. However, when the master data of the management server 110 is changed, the setting value of the multifunction device 120 is also used using the same process. May be changed. For example, the MFP 120 periodically polls (inquires) whether there is a change in master data to the management server 110, and if there is a change, sets the setting value corresponding to the change to the management server 110. It may be acquired from and reflected.

  As described above, when the MFP receives a setting change, the change contents are stored, and only when the storage is successful, the setting value DB is updated, and the management server is notified asynchronously to thereby reduce the waiting time of the user. It is possible to reliably manage the set value without increasing it.

(Second Embodiment)
In the first embodiment, the processing when the MFP 120 receives a change in the setting value from the user has been described. 2. Description of the Related Art In recent years, there are information processing apparatuses such as multifunction peripherals that can identify individual users and use preference settings for each user when a single device is shared by a plurality of users. For example, if a user uses black and white printing and often uses double-sided printing, by setting these settings in association with a specific button, the user simply presses this button after logging in to the device.・ Double-sided printing can be executed.

  In such an apparatus, settings that are reflected regardless of the user and settings that can be used only by a specific user are mixed. In this embodiment, even in such a case, the setting value can be efficiently managed between the management server and the multifunction peripheral.

  FIG. 9 is a diagram illustrating a configuration of the master data 401 according to the present embodiment. In the present embodiment, in order to manage setting values for each user, the master data 401 includes a user information DB 901 and a user setting value DB 902. FIG. 10A is a diagram illustrating data stored in the user information DB 901. The user information DB 901 is a database for managing information related to users who use the multifunction device 120. The user information DB 901 stores a user ID for uniquely identifying a user, a user name input by the user at the time of login, and the like.

  FIG. 10B is a diagram illustrating data stored in the user setting value DB 902. The user setting value DB 902 is a database for managing setting values for each user that can be used by each user who uses the multifunction machine 120. The user setting value DB 902 stores a user ID for uniquely identifying the user, a key identifier for uniquely identifying the setting value, and the contents of the setting value. This user ID has the same system as that in the user information DB 901.

  In this embodiment, it is assumed that the HDD 305 of the multifunction peripheral 120 also stores a database equivalent to the user information DB 901 and the user setting value DB 902 and is synchronized with the database on the management server 110. Here, only the processing of the present embodiment will be described in the flowchart shown in FIG.

  In the present embodiment, information indicating the type (category) of the set value is added to the job file stored in step S702. The type of setting value is information indicating a setting value that is reflected regardless of the user (for example, a setting value related to the device setting) or a setting value that is effective only for a specific user (setting value related to the user setting). is there. In addition, when a setting value effective only for a specific user is changed, the user identifier is included in addition to the job.

  In the present embodiment, one process similar to the process shown in FIG. 7B is further executed in parallel. That is, two processes shown in FIG. 7B are executed in parallel, but the determination process in step S710 is different between these two processes. In one process, in step S710, it is determined whether or not the setting value reflected regardless of the user is stored as a job. If it is stored (YES), the subsequent process is performed.

  In another process, in step S710, it is determined whether or not a setting value effective only for a specific user is stored as a job. If it is stored (YES), the subsequent process is performed. As described above, a plurality of jobs corresponding to different setting value types are simultaneously processed in parallel. When there are a plurality of jobs corresponding to the same set value type, the plurality of jobs are executed sequentially.

  If there is no dependency between the change of the setting value that is valid only for a specific user and the setting value that is reflected regardless of the user, the setting value change request to the management server is performed by the above processing. Can be performed in parallel at the same time as possible, so that rapid information transmission is possible.

  As described above, according to the present embodiment, the MFP 120 and the management server 110 can be used even when the setting described above is used and the setting reflected regardless of the user and the setting that can be used only by a specific user are mixed. Set values can be managed efficiently between
