JP5071663B2 - Storage device and information input method - Google Patents

Description

  The present invention relates to a storage device and an information input method.

  Storage devices for storing data are known. Data stored in the storage device is identified and managed as a file which is a collection of meaningful data by the file system. For example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-325271), Patent Document 2 (Japanese Patent Laid-Open No. 2001-290690), and Patent Document 3 (Japanese Patent Laid-Open No. 2007-172263) are examples of the file management technology. It is done.

  Usually, a user accesses a storage device via an electronic device such as a computer. Hereinafter, an electronic device that accesses a storage device and reads and writes data is referred to as a host device. For example, Patent Document 4 (Japanese Patent Laid-Open No. 2005-309501) describes a technique related to a program installed in a host device that accesses a memory card.

  Some storage devices are set by the user. For example, in an SD card with a built-in wireless LAN, an IP address or the like is set in the built-in wireless LAN device. When performing such setting, the user inputs complicated information such as numbers and character strings to the storage device as setting information. In order to input setting information, an input device (for example, a keyboard) capable of inputting complicated information is required.

  However, there are cases where only an electronic device that does not include a keyboard can be selected as the host device. For example, Japanese Patent Application Laid-Open No. 2006-109140 discloses a technique when a digital camera is used as a host device for a memory card. Digital cameras are also used on the go. It is assumed that the user goes out with only a digital camera and a wireless LAN built-in SD card. There is a case where a public wireless LAN can be used in the environment outside the office. In this case, in order for the wireless LAN built-in SD card to access the public wireless LAN service, setting information such as an IP address must be input to the wireless LAN built-in SD card. However, in the user interface provided in the digital camera, it is usually possible to input instructions for selecting, deleting, and browsing a file, and an IP address cannot be specified. Although the public wireless LAN service can be used environmentally, an IP address or the like cannot be set for the wireless LAN built-in SD card. As a result, the public wireless LAN service cannot be used.

(First embodiment)
The first embodiment of the present invention will be described below in detail with reference to the drawings. In the present embodiment, a memory card 2 incorporating a wireless LAN device will be described as an example of a storage device. The computer 1 will be described as an example of a host device that accesses the memory card 2.

  FIG. 1 is a functional configuration diagram schematically showing the memory card 2 and the computer 1.

  The memory card 2 includes a storage interface unit 22, a storage area 23, a file system unit 24, an interface manager unit 25, and a wireless LAN device 21. The interface manager unit 25, the storage interface unit 22, and the file system unit 24 operate by, for example, a program stored in advance in a ROM or the like being executed by a CPU or the like.

In this memory card 2, setting to the wireless LAN device 21 is generally performed by the following operation. First, the interface manager unit 25 writes data in the storage area 23 so that an interface file group including a plurality of files is created via the file system 24. At this time, the interface file group is created according to a preset file layout. In the file layout, the layout of a plurality of files and the correspondence between each of the plurality of files and meaning (unique information) are described.
When setting the wireless LAN device 21 is desired, the user accesses the memory card 2 via the computer 1. Then, a predetermined file is selected from the interface file group and deleted.
After the predetermined file is deleted by the user, the interface manager unit 25 reads the data stored in the storage area 23 via the file system 24. The interface manager unit 25 compares the read data with the file layout and identifies which file is deleted from the interface file group. Furthermore, the interface manager unit 25 identifies the meaning associated with the deleted file based on the file layout, and generates setting data (input data) based on the identification result. The generated setting data is notified to the wireless LAN device 21. The wireless LAN device 21 performs setting based on the acquired setting data.
Here, the computer 1 serving as the host device only needs to be provided with a user interface having a function capable of selecting and deleting a file. Even if an input device (for example, a keyboard) that can input complicated information is not provided in the computer 1 that is a host device, the user can input desired information to the memory card 2 via the computer 1. Settings (settings related to the wireless LAN device 21) can be made.

  Next, the configuration of each unit will be specifically described.

  The storage area 102 is an area for storing data, and is provided in the storage element.

  The storage interface unit 22 has an interface function with the computer 1 that is a host device. The storage interface unit 22 receives an input / output request from the computer 1 via a connector terminal (not shown), and writes and reads data to and from the storage area 23 based on the input / output request.

  The file system unit 24 is provided for managing the data stored in the storage area 23 as a file that is a group of meaningful data.

  The interface manager unit 25 reads out data stored in the storage area 102 via the file system unit 24 to identify what information is input from the user. Then, setting data is generated based on the identification result and notified to the wireless LAN 21.

  Specifically, the interface manager unit 25 writes data in the storage area 23 in accordance with a file layout set in advance in a ROM or the like. The file layout indicates the file layout in the interface file group. In addition, when a file included in the interface file group is deleted from the user via the computer 1, the interface manager unit 25 identifies which file is the deleted file. Then, by acquiring the meaning associated with the deleted file, input data is generated and notified to the wireless LAN 21.

Next, the file layout will be described. The file layout is information indicating the file layout in the interface file group and the meaning associated with each file. In the file layout, unique information (meaning) such as letters, numbers and setting contents is mapped to each file. Each file is a file that can be recognized by the computer 1 that is a host device, and includes content representing the associated meaning. In the present embodiment, a case where each file is a text file will be described.
FIG. 2 is a conceptual diagram showing an example of a file layout used when setting the IP address of the wireless LAN device. The IP address is a 32-bit numerical value. In order to make it easier for humans to read, 32 bits are represented by “.” Divided into 8 bits. Each 8 bits is represented by a decimal value from 0 to 255. For example, it is expressed in the form of 192.168.0.1. In order to specify such an IP address, the user must enter four decimal digits.
In the file layout shown in FIG. 2, an interface file named IPADDR is arranged in the top directory. In the file layout, this “IPADDR” is associated with information indicating that “the IP address of the wireless LAN device is set”. Below the “IPADDR” directory, directories 1st, 2nd, 3rd, and 4th are arranged. The “1th” directory is associated with the meaning of “the first 8 it number”. Further, “2th”, “3th”, and “4th” are associated with meanings indicating “second”, “third”, and “fourth” 8-bit numbers, respectively.
Files associated with numerical values of 0 to 255 are arranged under the 1st to 4th directories, respectively. The content and name of each file are preferably such that the meaning can be inferred when the user views the file via the host device. In the example shown in FIG. 2, a file having a file name “1st — 000.txt” is created under the 1st directory. The content of this file is “1st 0”. When the user refers to this file, the content of “1st 0” is notified to the user via the computer 1. The file name “1st — 000.txt” includes the character strings “1st” and “000”. When the user confirms the file name of the file, the meaning is easily associated with the file. Can be guessed. Similarly, “1st — 001.txt” to “1st — 255.txt” under the 1st directory, “2nd — 000.txt” to “2nd — 255.txt” under the 2nd directory, and “3rd — 000.txt” under the 3rd directory. To “3rd — 255.txt”, and “4th — 000.txt to 4th — 255.txt” are arranged below 4th.

  The computer 1 serving as the host device notifies the memory card 2 of an input / output request and inputs / outputs data to / from the memory card 2. The computer 1 also includes a file system (not shown) for identifying the data stored in the storage area 23 as a file. The file system provided in the computer 1 has the same file format as that of the file system 24 provided in the memory card 2, but is independent. The computer 1 used in the present embodiment may be a commercially available one, but does not necessarily have a keyboard, and can access the memory card 2 to select and delete data stored in the storage area 23. It only needs to have a user interface function that can be used. The user can refer to the interface file group of the memory card 2 by accessing the memory card 2 by the computer 1, and can perform file operations (selection and deletion).

  Next, the operation of the memory card 2 according to the present embodiment will be described. In the present embodiment, an operation when an IP address is set in the wireless LAN device 21 of the memory card 2 will be described. FIG. 3 is a flowchart showing the overall operation when the user sets an IP address in the memory card 2.

Step S10-1: Formatting Memory Card First, the memory card 2 is connected to the computer 1, and the storage area 23 in the memory card is formatted. By formatting, the data in the storage area 23 can be read and written in a specific format.

Step S20-1: Restart of Computer Next, the computer is restarted.

Step S30-1: Initialization of Memory Card and Creation of Interface File The computer 1 notifies an initialization request for using the memory card 2 at startup. In the memory card 2, an initialization process is executed. During the initialization process, the interface manager unit 25 reads data in the storage area 23 via the file system unit 24. The file does not exist immediately after formatting. Since the file does not exist, the file manager unit 25 writes data in the storage area 23 so that the interface file group is created according to the file layout. In order to avoid inconsistency with the file system provided on the computer 1 side, the setup to the memory card 2 performed when the computer is started is performed during the period in which the interface manager 25 can access the storage area 23. It shall be limited during the period. When the creation of the interface file group is completed, the interface manager unit 25 notifies the computer 1 side that the initialization is completed via the storage interface unit 22. Thereafter, access to the storage area 22 from the computer 1 side is permitted.

Step S40-1; Deletion of File When the user wants to input some information to the storage device, the user accesses the memory card 2 via the computer 1 and reads out the data stored in the storage area 22 to the computer 1. Then, the file corresponding to the IP address to be set is deleted from the interface file group. At this time, since each file is a text file, the user can easily guess what information is associated with the file by referring to the file. Also, the information associated with the file can be estimated by checking the file name. For example, when “192.168.0.1” is input as the IP address, the user transmits “IPADDR / 1st / 1st — 192.txt”, “IPADDR / 2nd / 2nd — 168.txt” via the computer 1. , “IPADDR / 3rd / 3rd — 0.txt” and “IPADDR / 4th / 4th — 001.txt” are deleted.

Step S50-1: Restarting the computer After deleting the interface file, the computer is restarted (step A5).

Step S60-1: Memory Card Input Recognition After the memory card is energized, the memory card 2 receives an initialization request from the computer again. As an initialization process in the memory card 2, the interface manager unit 25 reads data stored in the storage area 23 via the file system unit 25. Then, it is specified which file in the file layout is the file deleted in step S40-1. Based on the identification result, the meaning associated with the deleted file is acquired, and setting data is generated. The generated setting data is notified to the wireless LAN device 21. For example, when a file associated with the numbers “192”, “168”, “0”, and “1” is missing, the interface manager unit 25 selects “192”, “168”, “168” based on the file layout. The numbers “0” and “1” are acquired. Then, data indicating “192.168.0.1” is generated as setting data and notified to the wireless LAN device 21. In the wireless LAN device 21, an IP address is set based on the setting data.
After that, the interface manager unit 25 restores the interface file group based on the file layout. After the restoration, the computer 1 side is notified that the initialization has been completed, and access from the computer 1 side is permitted.

  With the above operation, the user can set the wireless LAN device 21 without using a keyboard or the like.

  Next, the operation on the memory card 2 side will be described in detail with reference to FIG.

Step S1-1: Initialization of Memory Card First, when the computer 1 is turned on, an initialization request is notified from the computer 1 side to the memory card 2 side. An initialization process is executed on the memory card 2 side.

Step S2-1: Recognition of Missing File During initialization of the memory card 2, the interface manager unit 25 reads data from the storage area 23 via the file system 24. Then, the file layout is compared with the read file to check whether there are any missing files in the interface file group.

Step S3-1: Determination of Missing File If there is a missing file in step S2-1, it is determined whether all or part of the interface file group is missing. If everything is missing, it is recognized that the memory card 2 has just been formatted, and the process proceeds to step S6-1. On the other hand, if only a part is missing, it is considered that information has been input by the user, and the next step S4-1 is executed.

Step S4-1: Generation of data for setting When it is determined in step S3-1 that some files are missing, the interface manager unit 25 creates a missing file based on a preset file layout. Get the mapped information and generate the setting data.

Step S5-1: Notification of Setting Data The interface manager unit 25 notifies the wireless LAN 21 of the generated setting data.

Step S6-1: Notification of setting data After the completion of Step S5-1 or when it is determined in Step S3-1 that all files are missing, the interface manager unit 25 sets a preset file layout. Based on the above, data is stored in the storage area 22 so that the interface file group is restored (created).

  After restoring the interface file group, the interlace manager unit 25 notifies the computer 1 side of the completion of the initialization process via the storage interface unit 22, and permits access from the computer 1 side.

  As described above, according to the present embodiment, even from a host device that does not have a user interface that can input complicated information, a user can create a storage device that does not originally have an input interface, such as a memory card. On the other hand, information can be input. In this embodiment, the computer 1 is exemplified as the host device. However, a function required as a user interface is file selection and deletion, and an input device such as a mouse may be connected.

  Further, according to the present embodiment, the file included in the interface file group is a text file, and the file name or the contents of the file represents the meaning associated with the file, so that the user can refer to the text file. The meaning associated with each file can be easily guessed on a device capable of doing so.

  In this embodiment, the case where the setting value of the wireless LAN device is input has been described. However, the input data is not limited to the setting value of the wireless LAN device, and may be the setting value of other devices.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a functional configuration diagram schematically showing the storage device (memory card 2) according to the present embodiment. This embodiment is different from the first embodiment in that a digital camera 3 is used as a host device. In the memory card 2, the interface manager unit 25 creates an image file as an interface file group instead of a text file. Since other points are the same as those in the first embodiment, detailed description thereof is omitted.

  The digital camera 3 is configured to access the storage area 23 via the storage interface 22 of the memory card 2 and to store, delete, and refer to an image file by a user operation. The digital camera 3 includes a display screen (not shown), and the content (content) of the designated image file is displayed as an image on the display screen.

  FIG. 6 is a conceptual diagram showing a file layout set in the present embodiment. This file layout conforms to DCF (Design rule for Camera File System) established by JEITA (Japan Electronics and Information Technology Industries Association). According to the DCF format, a directory called DCIM is arranged in the top directory, and a directory having a name composed of a 3-digit number and a 5-digit alphabet is arranged below the top directory. Furthermore, an Exif file format image file having a file name composed of three alphanumeric characters (upper case), four numeric characters, and an extension is arranged. More specifically, directories called 100CONFI, 101MENU, 111STRIN,... 11nSTRIN (n is an integer) are arranged under the DCIM directory.

  100CONFI is a directory relating to the setting status. 100CONFI includes a “current setting” file and a “clear setting” file. The “current setting” file is an image file indicating the current setting value. When a “current setting” file is selected and referred to by the user from the interface file group, an image indicating the current setting value is displayed on the display screen of the digital camera 3. The “clear setting” file is associated with information indicating that the setting is cleared. When the “clear setting” file is deleted from the interface file group, the interface manager unit 25 generates data for deleting all existing settings.

  101 MENU is a directory for selecting setting items. In 101MENUS, an “SSID (Service Set Identifier)” file and an “encryption scheme” file are arranged. The “SSID” file is a file for designating “SSID” as a setting item of the wireless LAN. When the “SSID” file is deleted by the user, “SSID” is designated as a setting item. The “encryption method” is a file for specifying an encryption method as a setting item. When the “encryption scheme” file is deleted by the user, “encryption scheme” is designated as a setting item.

  111STRIN,... 11nSTRIN (n is an integer) is a directory for supporting the input of a character string. The third character of each directory means the nth character of the character string. For example, “111 STRIN” is a directory for designating the first character string, and “115 STRIN” is a directory for designating the fifth character string. Each directory is associated with an image file associated with alphanumeric characters a, b,..., Z, 0, 1,..., And a SIFT that converts the alphanumeric characters from lowercase to uppercase. An image file is stored. The content of the image file (the content displayed on the display screen when referred to by the user) may be modified so that it is easy to understand other than the associated characters. For example, in the example shown in FIG. 6, an image file including the content “1st:” is stored so that the meaning of “first character” can be easily understood.

  Next, the operation of this embodiment will be described.

FIG. 7 is a flowchart showing the overall operation when the user sets the wireless LAN device 21 from the digital camera 3. Similar to the first embodiment, the memory card 2 is formatted by the digital camera 3 (step S10-2), and then the digital camera 3 is restarted (step S20-2). When the digital camera 3 is activated, an initialization process is performed on the memory card 2 side, and the interface file group shown in FIG. 6 is created (step S30-2). Next, the user reads out a file stored in the storage area 22 of the memory card 2 via the digital camera 3.
Specifically, a case where “SSID” is selected as “setting item” and a character string “abc” is set will be described. The user selects the “SSID” file in the “101MENU” directory, the “a” file in the “111STRIN” directory, the “b” file in the “112STRIN” directory, and the “c” file in the “113STRIN” directory from among the read files. Is deleted (step S40-2). Thereafter, the digital camera 3 is restarted (step S50-2). Then, when the digital camera 3 is activated, the memory card 2 performs the initialization process again. At this time, the interface manager unit 25 reads data from the storage area 22 and recognizes that there is a deleted file from the interface file group (step S60-2). The missing file is a file corresponding to the setting item “SSID”, a file corresponding to the first character string “a”, the second character string “b”, and the third character string “c”. The interface manager unit 25 determines that the user has input that the character string “abc” is designated as “SSID”. The interface manager unit 25 generates data for designating the character string “abc” as “SSID” as setting data, and notifies the wireless LAN device 21 of the data. The wireless LAN device 21 performs setting based on the acquired setting data (S60-2). Thereafter, the interface manager unit 25 restores the interface file group and permits access from the digital camera 3 side.

  Next, the operation on the memory card 2 side will be described with reference to FIG. FIG. 8 is a flowchart showing an operation when the memory card 2 is energized by the digital camera 3.

  When the memory card 2 is energized from the digital camera 3, the interface manager unit 25 starts an initialization process (step S1-2). The interface manager unit 25 reads data from the storage area 23 via the file system unit 24, and checks whether there is a missing file from the interface file group (step S2-2). If it is missing, it is determined whether all files or only some of the files are missing from the interface file group (step S3-2). If all the files are missing, the process of step S8-2 is executed. If only some files are missing, the process of the next step S4-2 is executed.

  If only some files are missing from the interface file group, the interface manager unit 25 checks whether the “setting clear” file has been deleted (step S4-2). If the “clear setting” file has been deleted, it is assumed that the user has input a request to clear the wireless LAN setting, and data indicating that the setting is cleared is generated to generate the wireless LAN device. 21 is notified. In the wireless LAN device 21, the existing setting is cleared (returned to the initial value). Thereafter, the process proceeds to step S8-2. If the “clear setting” file has not been deleted, the process of the next step S5-2 is executed.

  When the “clear setting” file is not missing, the interface manager unit 25 identifies the deleted file among the files associated with the character string, and creates data indicating the character string based on the identification result. (Step S5-2). Similarly, the deleted file is identified among the files associated with the setting item, and it is determined which setting item is selected based on the identification result (step S6-2). For example, when a file associated with “SSID” has been deleted, data indicating “SSID” is created as a setting item. The interface manager unit 25 creates setting data by combining the created character string data and setting item data, and notifies the wireless LAN device 21 of the setting data. As a result, in the wireless LAN device 21, the existing setting is rewritten with the content of the notified setting data (step S7-2).

  After execution of step S7-2 or when all the files are missing in step S3-2, the interface manager 25 writes data in the storage area 23 and creates (restores) an interface file group. Thereafter, the interface manager unit 25 notifies the digital camera 3 that the initialization process has been completed via the storage interface 22, and permits access from the digital camera 3 (step S8-2).

  As described above, according to the present embodiment, since the interface file group includes the image file, it is possible to perform settings for the memory card 2 using a device that can refer to and delete the image file as a host device. .

  Further, since the contents of the image file indicate the meaning associated with the file in the file layout, when the user selects and refers to the file with the host device (digital camera 3), which file is referred to It can be confirmed as an image whether it is associated with such meaning. As a result, the user can definitely delete the file corresponding to the information to be input.

  In addition, since the setting data is created based on the files deleted from the interface group, the user need only delete the minimum number of files. If data for setting is created based on the files left in the interface group, the user has to delete a large number of files. Some host devices do not allow selection of a plurality of files at a time, depending on the type, and the files must be deleted one by one. On the other hand, according to the present embodiment, the user can easily input information.

The present invention has been described with reference to the first and second embodiments. However, the present invention is not limited to the above-described embodiment. These embodiments can also be used in combination.
For example, in the above-described embodiment, a case where a memory card is used as the storage device and a computer and a digital camera are used as the host device has been described. However, a file system having the same file format is installed in the host device and the storage device. If it is, combinations other than those described above are possible.
Further, the configuration of the file layout can be appropriately changed depending on what information can be input to the storage device, the specifications of the user interface provided in the host device, and the like.
