[0003] [Patent Document 1] Japanese Patent Application Publication No. 01-199116 Summary of the Invention [Problem to be solved by the invention]

[0004] When there are multiple files storing setting data in the above-mentioned measuring device, the only way for a user to find out what setting data is stored in the files is to load the multiple setting data into the measuring device one by one, or to look at the file name of the setting data.

[0005] Furthermore, there was a problem in that the operation of loading the setting data files into the measuring device one by one became more difficult as the number of files increased, and the task of creating file names that enable the contents of the setting data to be identified became more difficult as the amount of information in the setting data increased.

[0006] An object of the present invention is to provide a file generation device, a measurement device, and a file generation method that generate a file that allows easy examination of what setting data is stored in the file. [Means for solving the problem]

[0007] According to one aspect of the present invention, a file generating device includes an image acquiring means for acquiring image data representing information about a measurement process executed by a measurement device, and an information acquiring means for acquiring coded data including the information represented in the image data. The file generating device further includes a generating means for storing the coded data together with the image data in an image file to generate the image file. the information acquiring means acquires, as the encoded data, setting data indicating measurement conditions to be set in the measuring device, the image acquiring means acquires, as the image data, setting image data displaying the measurement conditions, and the generating means stores the setting data and the setting image data in the image file. . Effect of the Invention

[0008] According to this aspect, the file generating device stores both image data representing information related to the measurement process and coded data containing the same content as the information represented in the image data in an image file. By using an image file as a file for storing coded data in this way, a user can display the image data representing information related to the measurement process using, for example, an image viewer function of a personal computer without a special device.

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0013] FIG. 1 is a block diagram showing the functional configuration of a measurement device according to an embodiment of the present invention.

[0014] The measuring device 1 in this embodiment executes a measurement process for measuring a physical quantity of a measurement target. The measuring device 1 functions as a file generating device for generating an image file. The file generating device generates an image file including an information area for storing information composed of letters, numbers, symbols, or a combination thereof, and an image area for storing image data that displays the information in a format that can be recognized (understood) by a person.

[0015] The measuring device 1 is realized by, for example, a power analyzer, a voltage measuring device, or a current measuring device. The measuring device 1 is configured with a processor, a ROM (Read Only Memory), a RAM (Random Access Memory), an input / output interface, and a bus that interconnects these.

[0016] The measurement device 1 includes an operation unit 10, a measurement processing unit 20, a memory unit 30, an image generation unit 40, a display unit 50, a data processing unit 60, a file processing unit 70, a file memory unit 80, a communication unit 90, and a control unit 100.

[0017] The operation unit 10 is composed of a plurality of push buttons provided around the display screen constituting the display unit 50, a touch sensor arranged within the display screen, or a keyboard and a mouse, etc. The operation unit 10 accepts an input operation by a user who uses the measuring device 1, and generates an operation signal indicating the content of the accepted input operation.

[0018] Examples of input operations include an operation of pressing the power button, an operation of setting measurement conditions, an operation of instructing the execution of a measurement process, an operation of instructing the end of a measurement process, and an operation of instructing the generation of an image file.

[0019] When the operation unit 10 receives an input operation by the user to set measurement conditions, the operation unit 10 outputs an operation signal indicating the measurement conditions to the control unit 100 in order to record the operation signal in the storage unit 30 as setting information 31. Furthermore, when the operation unit 10 receives an input operation by the user to instruct the execution of a measurement process, the operation unit 10 outputs an operation signal indicating the content of the input operation to the control unit 100.

[0020] The measurement processing unit 20 executes a measurement process for measuring a physical quantity of a measurement object. For example, the measurement processing unit 20 controls the operation of one or more sensors, measures the magnitude of power transmitted to an electric power line as a measurement object, and generates a measurement signal indicating the measured value in a time series.

[0021] Specifically, the measurement processing unit 20 calculates a measurement value of the power transmitted to the electric power line based on a detection signal output from one or more sensors for detecting the current and voltage generated in the electric power line. The measurement processing unit 20 outputs a measurement signal indicating the calculated measurement value in chronological order to the control unit 100 so that the measurement signal can be recorded in the storage unit 30 as result information 32.

[0022] The storage unit 30 is composed of a RAM and a ROM, and stores information related to the measurement processing executed by the measurement processing unit 20. The storage unit 30 records encoded data in which letters, numbers, symbols, etc. are encoded, as information related to the measurement processing.

[0023] The encoded data may be, for example, binary data or text data. The encoded data in this embodiment is recorded in the storage unit 30 in binary format. This allows the amount of encoded data to be reduced compared to when the data is recorded in text format. In addition, it is possible to suppress alteration of information while ensuring confidentiality of the information.

[0024] The storage unit 30 in this embodiment stores setting information 31, which is encoded data of information related to the measurement process, and result information 32. The setting information 31 is setting data indicating the measurement conditions set in the measurement device 1, and the result information 32 is result data indicating the measurement results obtained by executing the measurement process.

[0025] The storage unit 30 also stores a program for the control unit 100 to execute the file generation process of this embodiment. That is, the storage unit 30 is a computer-readable storage medium on which a program for controlling each part of the measurement device 1 is recorded.

[0026] The image generating unit 40 constitutes an image acquiring means for acquiring image data that represents information related to the measurement process of the measuring device 1 in a format recognizable by a user. The image generating unit 40 in this embodiment generates image data that represents all or part of the information stored in the storage unit 30 in a predetermined format.

[0027] For example, the image generating unit 40 generates setting image data in which measurement conditions such as setting items shown in the setting information 31 are displayed in a format recognizable by the user, such as letters, numbers, and symbols, and outputs the setting image data to the display unit 50. The setting image data will be described later with reference to FIG.

[0028] Furthermore, the image generating unit 40 generates result image data that displays the time-series measurement values ​​shown in the result information 32 in a format that can be recognized by the user, such as a table or graph. Examples of graphs displayed by the result image data include bar graphs and histograms.

[0029] For example, the image generating section 40 generates waveform image data showing a waveform diagram of the measurement signal as result image data based on the result information 32. The image generating section 40 outputs the generated result image data to the display section 50.

[0030] The display unit 50 is configured with a liquid crystal panel, a touch panel, or the like for displaying images. The display unit 50 constitutes a display means for displaying image data acquired by the image generating unit 40. As a specific example, the display unit 50 displays setting items indicating measurement conditions on the display screen based on setting image data, and displays a waveform diagram of a measurement signal on the display screen based on result image data.

[0031] The data processing unit 60 constitutes an information acquiring means for acquiring coded data including information represented by image data from the image generating unit 40. The data processing unit 60 records coded data indicating information related to the measurement processing of the measuring device 1 in the storage unit 30. Then, the data processing unit 60 reads out the recorded coded data from the storage unit 30 in accordance with a command from the control unit 100.

[0032] The data processing unit 60 in this embodiment encodes the operation signal indicating the measurement conditions from the operation unit 10 into a binary format, and records the encoded data in the storage unit 30 as the setting information 31 .

[0033] Then, when the operation unit 10 accepts an input operation instructing generation of an image file, the data processing unit 60 reads the setting information 31 from the storage unit 30, and outputs the setting information 31 to the image generation unit 40 via the control unit 100. Next, the data processing unit 60 acquires the setting image data from the image generation unit 40, and outputs the acquired setting image data and the setting information 31 corresponding to the setting image data to the file processing unit 70.

[0034] Furthermore, in this embodiment, the data processing unit 60 encodes the measurement signal indicating the measurement result from the measurement processing unit 20 into a binary format, and records the encoded data in the storage unit 30 as result information 32 .

[0035] Then, when the operation unit 10 accepts an input operation instructing generation of an image file, the data processing unit 60 reads out the result information 32 from the storage unit 30, and outputs the result information 32 to the image generation unit 40 via the control unit 100. Next, the data processing unit 60 obtains the result image data from the image generation unit 40, and outputs the result information 32 to the file processing unit 70 together with the resultant image data.

[0036] The file processing unit 70 constitutes a generating means for storing coded data indicating information related to the measurement process and image data representing all or a part of the information in an image file. As the image file, for example, a predetermined image file having versatility is used, and specifically, a PNG (Portable Network Graphics) file, a JPEG (Joint Photographic Experts Group) file, etc. are mentioned.

[0037] In this embodiment, when the file processing unit 70 receives a command to generate an image file from the data processing unit 60, it acquires the above-mentioned encoded data and corresponding image data from the data processing unit 60. Then, the file processing unit 70 generates a PNG file by storing the acquired encoded data and image data in a PNG file.

[0038] For example, the file processing unit 70 acquires the setting information 31 and setting image data based on the setting information 31 from the data processing unit 60. Then, the file processing unit 70 compresses the setting image data and stores the compressed setting image data in the image area of ​​the PNG file, and also stores the setting information 31 in the information area of ​​the PNG file.

[0039] Alternatively, the file processing unit 70 acquires the result information 32 and result image data based on the result information 32 from the data processing unit 60. Then, the file processing unit 70 compresses the result image data and stores the compressed result image data in the image area of ​​the PNG file, and also stores the result information 32 in the information area of ​​the PNG file.

[0040] At this time, the file processing unit 70 may compress the result information 32, which is encoded data of the measurement signal in which a large number of measurement values ​​are indicated in a time series, and store the compressed result information 32 in the information area of ​​the PNG file. Generally, the size of the result information 32 is relatively large. For this reason, by compressing the result information 32 in the same way as image data and storing it in the PNG file, the size of the PNG file can be reduced.

[0041] In this way, the file processing unit 70 stores information related to the measurement process and image data representing all or part of this information in an image file. The file processing unit 70 outputs the generated image file to the file storage unit 80.

[0042] The file storage unit 80 is composed of a RAM and a ROM. The file storage unit 80 stores image files generated by the file processing unit 70. The file storage unit 80 may be configured as one unit with the storage unit 30. Alternatively, the file storage unit 80 may be configured as a separate unit from the measurement device 1, and may be configured as an external memory such as a USB memory that can be connected to the measurement device 1.

[0043] The communication unit 90 is configured with a communication circuit that communicates with the outside. For example, the communication unit 90 transmits or receives the image file generated by the file processing unit 70 to or from an external device wirelessly or wired via a network such as the Internet network or a telephone network.

[0044] In addition, in a situation where the setting information 31 or the result information 32 is managed in an external device, the communication unit 90 may transmit or receive the setting information 31 or the result information 32 from the external device. In this case, the communication unit 90 outputs the setting information 31 or the result information 32 to the control unit 100 in order to store the setting information 31 or the result information 32 in the storage unit 30.

[0045] The control unit 100 is a computer that controls each part of the measurement device 1. The control unit 100 is configured with a processor. Examples of the processor include a CPU (Central Processing Unit) and an MPU (Micro Processor Unit).

[0046] In this embodiment, when the control unit 100 receives, for example, an operation signal from the operation unit 10 instructing the generation of a PNG file related to the setting information 31, it issues a file generation command to the data processing unit 60 and acquires the setting information 31 from the data processing unit 60.

[0047] Then, control unit 100 controls image generation unit 40 to obtain setting image data for displaying the contents of setting information 31 on the screen, and outputs the setting image data to data processing unit 60. In accordance with a command from data processing unit 60, file processing unit 70 stores setting information 31 together with the setting image data in a PNG file to generate a PNG file. File processing unit 70 outputs the generated PNG file to file storage unit 80.

[0048] Thereafter, when the operation unit 10 receives an input operation from the user instructing to display the image file, the control unit 100 controls the data processing unit 60 to acquire the setting image data contained in the PNG file recorded in the file storage unit 80.

[0049] More specifically, in accordance with an instruction from data processing unit 60 , file processing unit 70 reads a PNG file from file storage unit 80 , obtains the setting image data stored in the information area of ​​the PNG file, and outputs it to data processing unit 60 .

[0050] Next, the control unit 100 outputs the acquired setting image data to the image generating unit 40, thereby causing the display unit 50 to display the measurement conditions indicated in the setting information 31.

[0051] Next, a configuration example of the operation unit 10 in the measurement device 1 will be described with reference to FIG.

[0052] 2 is a front view of the measurement device 1 in this embodiment. In the example shown in Fig. 2, a USB memory is inserted into an insertion slot 81 as the file storage unit 80 shown in Fig. 1.

[0053] The operation unit 10 includes a display screen 11 constituting a touch panel, a power switch 12, a file screen button 13, a measurement condition setting button 14, a measurement screen button 15, a data save button 16, and a recording start / stop button 17.

[0054] For example, when the measurement condition setting button 14 is pressed by a user, the measurement conditions such as the type of physical quantity of the object to be measured, the resolution, and the measurement range RANGE for each channel CH are displayed on the display screen 11. The measurement conditions are set by the user pressing various buttons (not shown) or inputting information into the touch panel display screen 11. As a result, setting information 31 indicating the set measurement conditions is recorded in the storage unit 30.

[0055] Furthermore, when the user presses the file screen button 13, a field for inputting the file name of the image file and keyboard buttons are displayed on the display screen 11. In this state, the user can set the file name by operating the keyboard buttons.

[0056] At this time, when the data save button 16 is pressed by the user, an operation signal instructing the generation of an image file is output from the operation unit 10 to the control unit 100. As a result, an image file storing the setting information 31 together with the setting image data is recorded in the USB memory.

[0057] In addition, when the user presses the record start / end button 17, the measurement results are recorded sequentially in the memory unit 30 shown in Figure 1, and when the user presses the record start / end button 17 again, recording of the measurement results in the memory unit 30 ends and result information 32 is generated.

[0058] At this time, when the data save button 16 is pressed by the user, an operation signal instructing the generation of an image file is output from the operation unit 10 to the control unit 100. As a result, for example, an image file storing the result information 32 together with the waveform image data is recorded in the USB memory.

[0059] Next, the setting image data stored in the image file will be described with reference to FIG.

[0060] 3 is a diagram showing an example of an image 82 generated from the setting image data in this embodiment. In this example, the image 82 is displayed on the display screen 11 of the display unit 50.

[0061] In the image 82, as the measurement conditions indicated in the setting information 31, a serial number for identifying the setting information 31, and the wiring type, voltage range, and current range of the first channel CH1 to be measured are displayed.

[0062] In this way, by generating setting image data showing image 82 based on setting information 31, the contents of setting information 31 are displayed on display screen 11 in a format that the user can understand, allowing the user to easily understand the measurement conditions.

[0063] On the other hand, since the setting information 31 is binary data encoded in binary format, even if the setting information 31 is displayed on the display screen 11 in binary format, it is difficult for a user to decipher the measurement conditions shown in the setting information 31.

[0064] For this reason, the measuring device 1 generates image data showing the image 82 based on the setting information 31, associates the setting information 31 with the generated image data, and stores the image file. This allows the user to easily understand the measurement conditions by simply executing a process to read the image file.

[0065] 3 shows image 82 generated based on setting information 31 indicating simple measurement conditions for ease of understanding, but the setting conditions indicated in setting information 31 are not limited to this. For example, setting information 31 may be setting information indicating measurement conditions including multiple measurement items for six channels.

[0066] Next, the image file that stores the setting information 31 will be described with reference to Fig. 4. In this embodiment, the well-known internationally standardized PNG file is used as the image file.

[0067] FIG. 4 is a diagram showing a schematic diagram of the data format of a PNG file 800 in this embodiment.

[0068] The PNG file 800 is made up of a PNG file ID at the beginning that indicates an identifier for identifying the PNG file, and four chunks added to this.

[0069] The image header IHDR is a required chunk that indicates the format of the setting image data or resultant image data generated by the image generating unit 40 shown in FIG. 1, and the palette PLTE is a required chunk that indicates information on the color palette.

[0070] The image data IDAT is a required chunk indicating the image compressed data obtained by compressing the image data using the compression method indicated in the palette PLTE, and corresponds to the image area of ​​the image file in this embodiment. The image end IEND is a required chunk indicating the end of the image data IDAT.

[0071] On the other hand, the setting data seTt is an auxiliary chunk that can be set arbitrarily, and corresponds to the information area of ​​the image file in this embodiment. The setting data seTt stores the setting information 31 or the result information 32 shown in Fig. 1. When the result information 32 is stored in the setting data seTt, information compression data obtained by compressing the result information 32 by the file processing unit 70 may be stored.

[0072] Although the setting data seTt is placed between the image data IDAT and the image end IEND as an example, the present invention is not limited to this and the setting data seTt may be placed anywhere in an area where an auxiliary chunk can be placed.

[0073] In this way, by using a PNG file to associate information regarding the measurement process with image data representing that information, it becomes easier to manage the setting information 31 and result information 32 and the user can easily understand the contents.

[0074] Next, the operation of the control unit 100 constituting the measurement device 1 in this embodiment will be described with reference to FIGS.

[0075] 5 is a flowchart showing an example of the processing procedure of a file generation method for generating an image file. In this example, a USB memory inserted into an insertion slot 81 of the measurement device 1 serves as the file storage unit 80.

[0076] First, the user presses the file screen button 13 of the measurement device 1 shown in Fig. 2, and the name of the image file to be recorded in the file storage unit 80 is set on the touch panel display screen 11. Then, when the data save button 16 of the measurement device 1 is pressed, an operation signal instructing the generation of an image file is supplied from the operation unit 10 to the control unit 100.

[0077] As a result, the control unit 100 controls the data processing unit 60 to obtain coded data indicating information related to the measurement processing of the measurement device 1. As a specific example, the control unit 100 issues a command to the data processing unit 60 to read the setting information 31 from the storage unit 30. As a result, the control unit 100 obtains the setting information 31 in binary format.

[0078] In step S1, the control unit 100 controls the image generating unit 40 to obtain image data that represents information related to the measurement process of the measuring device 1 in a format that can be recognized by the user.

[0079] 3, the control unit 100 issues a command to the image generating unit 40 to generate setting image data indicating an image 82 based on the setting information 31. As a result, the control unit 100 acquires the setting image data indicating the image 82 from the image generating unit 40.

[0080] In step S2, the control unit 100 obtains encoded data of the information represented in the obtained image data.

[0081] As a specific example, the control unit 100 identifies the binary setting information 31 used to generate the acquired setting image data from the information stored in the storage unit 30. As a result, the control unit 100 acquires the binary setting information 31 as coded data indicating information corresponding to the setting image data.

[0082] In step S3, the control unit 100 controls the file processing unit 70 via the data processing unit 60 to store in an image file the encoded data including the information represented in the image data together with the image data representing the information related to the measurement processing of the measurement device 1. This generates an image file having the information related to the measurement processing of the measurement device 1 and the image data representing that information in a format recognizable by the user.

[0083] As a specific example, the control unit 100 instructs the file processing unit 70 to store compressed image data obtained by compressing the setting image data in the image data IDAT, as shown in FIG. 4, and to store the setting information 31 corresponding to the setting image data in the setting data seTt.

[0084] In this way, the file processing unit 70 generates a PNG file 800 that stores the setting information corresponding to the setting image data. The PNG file 800 is then recorded in the USB memory that constitutes the file storage unit 80.

[0085] When the process of step S3 ends, the series of process steps for the file generation method according to this embodiment ends.

[0086] FIG. 6 is a flowchart showing an example of a processing procedure of a file reading method for reading the image file generated in FIG.

[0087] In step S11, when the control unit 100 receives an operation signal from the operation unit 10 instructing acquisition of encoded data, the control unit 100 controls the file processing unit 70 to acquire the setting information 31 stored in the information area of ​​the image file.

[0088] As a specific example, the control unit 100 issues a command to the file processing unit 70 to acquire the setting information 31 stored in the setting data seTt of the PNG file 800 from the file storage unit 80. As a result, the control unit 100 acquires the setting information 31 in binary format from the file processing unit 70.

[0089] In step S12, the control unit 100 judges whether or not an operation signal instructing execution of a measurement process has been received from the operation unit 10. If the control unit 100 has not received an operation signal instructing execution of a measurement process from the operation unit 10, the control unit 100 ends the processing procedure of the file reading method in this embodiment.

[0090] In step S13, the control unit 100 controls the measurement processing unit 20 to execute the measurement process based on the binary format setting information 31. When the process of step S13 ends, the series of process steps for the file reading method in this embodiment ends.

[0091] The effects of this embodiment will be described in detail below.

[0092] The measurement device 1 functioning as a file generating device in this embodiment includes an image generating section 40, a data processing section 60, and a file processing section .

[0093] The image generating unit 40 functions as an image acquiring means for acquiring image data representing information related to the measurement process executed by the measuring device 1, and the data processing unit 60 functions as an information acquiring means for acquiring coded data indicating the above information represented in the image data acquired by the image generating unit 40. The file processing unit 70 functions as a generating means for storing the above coded data together with the acquired image data in an image file and generating the image file.

[0094] Moreover, the file generation method in this embodiment includes the processes of steps S1 to S3 as shown in FIG.

[0095] Step S1 corresponds to an image acquiring step of acquiring image data representing information related to the measurement process executed by the measurement device 1, and step S2 corresponds to an information acquiring step of acquiring coded data indicating the information represented in the acquired image data. Furthermore, step S3 corresponds to a generating step of storing the coded data acquired in step S2 together with the image data acquired in step S1 in an image file to generate the image file.

[0096] According to these configurations, the measurement device 1 as a file generating device and the file generating method store both the encoded data of the information related to the measurement process and the image data representing the information in an image file. By using a general-purpose image file as a file for storing the encoded data in this way, a user can display the image data representing the information related to the measurement process on a screen using, for example, an image viewer function of a personal computer, even without a special device.

[0097] In this way, by storing the setting data as coded data in the image file of this embodiment, it is possible to easily check what setting data is stored.

[0098] Furthermore, by opening multiple image files simultaneously or displaying multiple image files in a list format, the user can easily check what kind of measurement processing information encoded data is stored in the image file. Since the image file of this embodiment also stores encoded data represented by image data, the measurement device 1 can also read encoded data related to the settings of the measurement device 1, such as measurement conditions, by reading this image file.

[0099] Therefore, even if there is a large number of image files storing information related to measurement processes, it becomes easy to select the image file storing the encoded data related to the target measurement process, so that the physical quantity of the object to be measured can be appropriately measured.

[0100] Moreover, the measurement device 1 in this embodiment further includes a measurement processing section 20, which functions as a measurement means for executing a measurement process for measuring a physical quantity of a measurement object.

[0101] According to this configuration, the measurement is made possible by the file generating device that can easily manage related data while allowing the user to understand the contents of the data related to the measurement process. This allows the measurement and file generation that can easily manage data related to the measurement to be performed by the same device.

[0102] Furthermore, the data processing unit 60 in this embodiment acquires setting information 31 (setting data) indicating measurement conditions set in the measurement device 1 as encoded data of information related to the measurement process of the measurement device 1. The image generating unit 40 acquires, as the above image data, setting image data that displays the measurement conditions indicated in the setting information 31. Then, the file processing unit 70 stores the setting image data based on the setting information 31 and the setting information 31 in an image file.

[0103] According to this configuration, together with the setting image data, setting information 31 indicating the same measurement conditions as those displayed in the setting image data is stored in the image file. Accordingly, the user can correctly identify the image file indicating the measurement conditions intended by the user by reading the image file and displaying the measurement conditions. Therefore, the user can cause the measurement device 1 to execute the measurement process according to the setting information 31 stored in the image file indicating the measurement conditions intended by the user.

[0104] That is, the user can avoid erroneously selecting setting information 31 that indicates measurement conditions different from the measurement conditions indicated in the setting image data.

[0105] In particular, the setting information 31 in this embodiment is composed of binary data. This reduces the amount of data in the setting information 31 while reducing the risk of a third party tampering with the measurement conditions. Therefore, it is possible to perform the measurement intended by the user while reducing the storage capacity of the measurement device 1.

[0106] The measurement device 1 in this embodiment further includes a display unit 50 that functions as a display means capable of displaying image data acquired by the image generating unit 40. The data processing unit 60 then acquires setting information 31 included in the image file, and the measurement processing unit 20 executes measurement processing based on the setting information 31 acquired by the data processing unit 60.

[0107] According to this configuration, the measurement device 1 can execute a measurement process based on the setting information 31 stored in the image file simply by reading the image file. Therefore, the setting information 31 and the setting image data can be easily managed without degrading the operability for the user.

[0108] For example, the measurement device 1 may operate as follows. In the measurement device 1, the display unit 50 displays the setting image data stored in an image file. After that, when the data processing unit 60 receives a command to execute a measurement process of the measurement device 1, it acquires the setting information 31 included in the image file storing the setting image data displayed on the display unit 50. Then, the measurement processing unit 20 executes the measurement process based on the setting information 31 acquired by the data processing unit 60.

[0109] Alternatively, the data processing unit 60 may receive a command to execute the measurement process of the measurement device 1 in a state in which it has acquired the setting information 31 contained in an image file storing the setting image data displayed on the display unit 50. In this case as well, the measurement processing unit 20 executes the measurement process based on the setting information 31 acquired by the data processing unit 60.

[0110] Thus, in the measurement device 1, the display unit 50 displays the setting image data stored in the image file. Thereafter, the data processing unit 60 acquires the setting information 31 included in the image file storing the setting image data displayed on the display unit 50, and the measurement processing unit 20 executes the measurement process based on the setting information 31 acquired by the data processing unit 60.

[0111] According to this configuration, compared to a case where the setting information 31 and the setting image data are managed separately, it is possible to prevent the user from selecting setting information different from the setting information 31 corresponding to the setting image data when performing the measurement process. This makes it possible to carry out the measurement intended by the user.

[0112] In this embodiment, the data processing unit 60 acquires result information 32 (result data) indicating the measurement results by the measurement device 1 as coded data, and the image generating unit 40 acquires result image data displaying the measurement results as image data. The file processing unit 70 then stores the result information 32 and the result image data in an image file.

[0113] According to this configuration, the result information 32 showing the same content as the measurement result displayed in the result image data is stored in the image file together with the result image data. Accordingly, the user can correctly identify the image file showing the measurement result intended by the user by reading the image file and displaying the measurement result.

[0114] Therefore, the user does not need to execute a process of generating result image data based on result information 32 in measuring device 1 each time in order to understand the contents of result information 32. Therefore, the processing load associated with understanding the contents of result information 32 can be reduced.

[0115] For example, the result information 32 is waveform data that indicates, in time series, measurement values ​​obtained by executing a measurement process in the measurement device 1, and the result image data is waveform image data that indicates a waveform diagram generated based on the waveform data.

[0116] In this example as well, it is no longer necessary to generate waveform image data based on waveform data, thereby enabling the user to easily understand the contents of the waveform data while reducing the processing load of generating waveform image data.

[0117] Although the embodiments of the present invention have been described above, the above-mentioned embodiments merely show some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above-mentioned embodiments.

[0118] For example, in this embodiment, the measuring device 1 executes the file generation process of storing the setting information 31 and the setting image data based on the setting information 31 in an image file, but the file generation process may be executed by a device separate from the measuring device 1. As a specific example, a separate file generation device acquires the setting information 31 from the measuring device 1, generates the setting image data based on the setting information 31, and executes the file generation process.

[0119] Furthermore, in this embodiment, the measurement device 1 is provided with the communication unit 90, but for example, the communication unit 90 may be omitted. [Explanation of symbols]
