  By the way, the setting data is generally stored as binary data in the internal memory of the electronic device, but the setting data (setting file) before being stored in the internal memory is compatible or customized between versions. It is not binary data but text data because of the nature of sex. Therefore, when setting data (binary data) is stored in the internal memory of the electronic device, it is necessary to convert the setting file (text data) into binary data. Therefore, the setting data is stored in the internal memory of the electronic device. There is a problem that it takes time. In addition, when setting data stored in advance in the internal memory of the electronic device is taken out of the electronic device, it is necessary to convert the setting data into text data. There is.

  Furthermore, if the setting data is stored as binary data in the internal memory of the electronic device, the firmware version installed in the electronic device may differ from the firmware version of the electronic device that generates the setting file. However, in such a case, the setting file may not be stored as setting data in the internal memory of the electronic device.

The present invention has been made in view of the above-described circumstances, and has the following objects.
(1) The processing time when the setting file is stored as setting data in the internal memory of the electronic device and / or the processing time when the setting data stored in advance in the internal memory of the electronic device is extracted to the outside is reduced as compared with the conventional case. .
(2) The setting file is stored as setting data in the internal memory of the electronic device regardless of the difference between the firmware version installed in the electronic device and the firmware version of the electronic device that generates the setting file.

  In order to achieve the above object, in the present invention, as a first solving means, there is provided a setting data storage unit for storing setting data including one or a plurality of setting values indicating operating conditions as binary data, and based on the setting data. An electronic device that performs a predetermined operation, an identifier table storage unit that stores an identifier table indicating a correspondence between a setting value and an identifier for identifying the setting value, and a version of firmware installed in the electronic device Version information storage means for storing information, setting data output means for outputting setting data to the outside, and assigning an identifier to a setting value in the setting data based on the identifier table and providing version information A data transfer control unit that causes the data output means to output the setting file is used.

  As a second solving means, in the first solving means described above, further comprising setting data obtaining means for obtaining a setting file from the outside, wherein the data transfer control unit includes the version information of the setting file obtained by the setting data obtaining means as version If it matches the version information of the information storage means, the setting data of the setting file is written to the setting data storage unit, and the version information of the setting file acquired by the setting data acquisition means does not match the version information of the version information storage means Adopts a means of writing only the setting value assigned with the same identifier as the identifier registered in the identifier table among the setting values of the setting file to the setting data storage unit.

  As a third solving means, in the first or second solving means, the data transfer control unit, when the identifier registered in the identifier table is not registered in the setting file, the setting value registered in the identifier table As an alternative, a means of writing in the setting data storage unit is adopted.

  As a fourth solving means, in the second or third solving means, the setting data output means and the setting data acquisition means are external recording medium interfaces that write setting data to the external storage medium and read from the external storage medium. , Is adopted.

  As a fifth solution, in the second or third solution, the setting data output unit and the setting data acquisition unit transmit the setting data to an external device based on a predetermined communication specification and set the setting data from the external device. A means of being a communication unit that receives data is adopted.

  According to the present invention, when setting data as binary data stored in the setting data storage unit is output to the outside via the setting data output means, the setting file is provided with an identifier and firmware version information added to the setting value. Output to the outside, that is, without assigning an identifier to the setting value in the setting data (binary data) and giving the firmware version information without converting the setting data (binary data) into text data as in the past. Therefore, it is possible to shorten the processing time when the setting data stored in the setting data storage unit in advance is taken out to the outside.

  According to the present invention, when the setting data in the setting file is stored in the setting data storage unit, if the version information of the setting file matches the version information in the version information storage means, the setting data of the setting file When the version information of the setting file does not match the version information of the version information storage means, the same identifier as the identifier registered in the identifier table is assigned among the setting values of the setting file. Since only the setting value is written in the setting data storage unit, the processing time can be shortened compared to the conventional method, and the setting data cannot be read from the setting file when the firmware version is different as before. Can be eliminated.

And the setting values R001, R002,. This is a table showing the correspondence with ID001, ID002,. In addition, attribute information indicating the contents and structure of the setting values R001, R002,... Is added to this identifier table for each identifier ID001, ID002,... (Each setting value R001, R002,...). ing. In addition, this identifier table may be provided in the data transfer control unit 3, for example, other than the setting data storage unit 7.

As shown in this figure, the setting file includes various setting values S001, S002,... And identifiers ID001, ID002,... Associated with the setting values S001, S002,. Includes version information. In such a configuration file, firmware version information is registered at the top, and identifiers ID001, ID002, ... and setting values S001, S002, ... are registered in pairs following this version information. Has been.

  The display unit 8 displays the waveform display of the measurement data described above, the operation state of the data storage device, and the like, and is a liquid crystal display, for example. The operation unit 9 is composed of a plurality of hardware keys, and accepts various operation instructions from the user who uses the data storage device. A system bus 10 is a signal transmission path composed of the input unit 1, the measurement data storage unit 2, the data transfer control unit 3, the external storage medium interface 4, an address line and a data line having a predetermined bit width, and a plurality of control lines. The external storage medium 5, the communication unit 6, the setting data storage unit 7, the display unit 8, the operation unit 9, and the calculation control unit 11 are interconnected so that signals can be transmitted and received.

  The arithmetic control unit 11 includes at least a CPU (Central Processing Unit) and a ROM (Read Only Memory) that stores a predetermined arithmetic control program. When the CPU executes the arithmetic control program, the arithmetic control program, the communication The input unit 1, the measurement data storage unit 2, the data transfer control unit 3, the external storage medium interface 4, the external storage based on the request received by the unit 6 from the external device and the operation instruction received by the operation unit 9 from the user. The medium 5, the communication unit 6, the setting data storage unit 7, the display unit 8, the operation unit 9, and the system bus 10 are comprehensively controlled.

  Here, the data transfer control program executed by the data transfer control unit 3 and the operation control program executed by the operation control unit 11 are application programs that operate on the firmware installed in the data storage device in advance. The arithmetic control unit 11 stores firmware and version information of the firmware in advance.

  Next, the main part operation (setting data saving process and loading process) of the data storage apparatus configured as described above will be described in detail with reference to FIG. 4 and FIG.

  First, the setting data saving process will be described with reference to FIG. In a state in which the external storage medium 5 is attached to the external storage medium interface 4, the data transfer control unit 3 reads the setting data from the setting data storage unit 7 (step S1), and binary data having a predetermined bit width is obtained from the setting data. A certain set value S001, S002,... Is cut out (step S2). Then, the data transfer control unit 3 refers to the identifier table described above, and assigns identifiers ID001, ID002,... To the set values S001, S002,. .

  Further, the data transfer control unit 3 stores in advance in the data transfer control unit 3 at the head of the data group composed of the pairs of the set values S001, S002,... And the identifiers ID001, ID002,. By adding firmware version information (that is, firmware version information of the data storage device that generated the setting file), a setting file having the data structure shown in FIG. 3 is generated (step S4). Then, the data transfer control unit 3 outputs the setting file generated in this way to the external storage medium interface 4 and saves it in the external storage medium 5.

  That is, in the setting data saving process in the data storage device, each setting value (binary data having a predetermined bit width) constituting the setting data stored in the setting data storage unit 7 is not converted into text data. The file is saved (saved) in the external storage medium 5 as a setting file that is paired with an identifier whose relationship is defined in advance and to which firmware version information is added. Therefore, according to the present data storage device, it is possible to shorten the time required for saving the setting data as compared with the prior art.

Next, setting data loading processing will be described with reference to FIG.
In a state where the external storage medium 5 is attached to the external storage medium interface 4, the data transfer control unit 3 acquires a setting file from the external storage medium 5 via the external storage medium interface 4 (step Sa1). Then, the data transfer control unit 3 determines whether or not the firmware version information registered at the top of the setting file matches the firmware version information stored in advance in the arithmetic control unit 11 (step Sa2). ).

  That is, version information different from that of the data storage device is registered in the setting file created by the data storage device in which the firmware version different from the firmware installed in the data storage device is installed. When such a setting file is attached to the external storage medium interface 4, the determination in step Sa2 is “No”, while a setting file in which version information matching the version information of the data storage device is registered is an external file. If it is attached to the storage medium interface 4, the determination in step Sa2 is “Yes”.

  If the two versions do not match, that is, if the determination in step Sa2 is “No”, the data transfer control unit 3 refers to the identifier table described above to set the setting value (predetermined bit width) registered in the setting file. (Binary data) is checked (step Sa3), and only the setting value (binary data having a predetermined bit width) assigned the same identifier as the identifier registered in the identifier table is written in the setting data storage unit 7 (step Sa4). ). On the other hand, if the determination in step Sa2 is “Yes”, the data transfer control unit 3 sequentially writes all setting values (binary data having a predetermined bit width) registered in the setting file in the setting data storage unit 7 (step S2). Sa4).

  Depending on the version relationship between the two, there may be a situation where the identifier registered in the identifier table is not registered in the setting file. In such a case, the data transfer control unit 3 causes the setting data storage unit 7 to write the setting value (initial value) registered in the identifier table as an alternative.

  According to such setting data loading processing, the setting value (binary data having a predetermined bit width) registered in the setting file is stored in the setting data storage unit 7 as binary data. There is no need to convert it to data, and therefore it is possible to shorten the time required for writing (loading) the setting data as compared with the prior art.

  Further, according to such setting data loading processing, when the firmware version information registered in the setting file is different from the firmware version information stored in advance in the arithmetic control unit 11, that is, the setting file is generated. When the firmware involved in the data and the firmware of the data storage device to which the setting data is written are different, the data having the same identifier can be written in the setting data storage unit 7, so that the versions are different as in the prior art. In this case, it is possible to avoid a situation in which the setting data cannot be written at all.

  In the above-described embodiment, the present invention is applied to a data storage device that is one of electronic devices. However, an electronic device that operates by storing a set value in an internal memory includes a measurement device, a display device, and the like. There are various things. The present invention can be applied to various electronic devices other than data storage devices.

  In the above embodiment, the setting data stored in the setting data storage unit 7 is saved in the external storage medium 5 and the setting data is written from the external storage medium 5 to the setting data storage unit 7, that is, the setting data output unit. The setting data acquisition means has been described for the external storage medium 5, but the present invention is not limited to this. The communication unit 6 may be used instead of the external storage medium 5, or the external storage medium 5 and the communication unit 6 may be used as the setting data output unit and the setting data acquisition unit.
