Description

[Technical field]

[0001] The present disclosure relates to an information processing device, an information processing system, an information processing method, a program, and a measuring instrument. [Background technology]

[0002] Conventionally, there are known techniques related to searching for measurement data files generated by a measuring device performing a measurement process on a measurement target. For example, Patent Document 1 discloses a measurement data processing device that easily and efficiently searches for measurement result data and various information data. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-267499 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the prior art, in an information processing system in which a measuring device and a server are connected to each other so that they can communicate with each other, measurement data files are transmitted from the measuring device to the server and centrally managed by the server. In this case, if the file size of the measurement data file is large, the load on the network and the server becomes large.

[0005] An object of the present disclosure is to provide an information processing device, an information processing system, an information processing method, a program, and a measuring instrument that are capable of reducing the load caused by data communication. [Means for solving the problem]

[0006] An information processing device in some embodiments is an information processing device that is communicatively connected to a measuring instrument and includes a control unit, wherein the control unit acquires metadata from the measuring instrument that is associated with a measurement data file acquired by the measuring instrument, and stores the metadata in a database used to search for a specific measurement data file stored in the measuring instrument.

[0007] This makes it possible to reduce the load caused by data communication. For example, the information processing device acquires metadata associated with a measurement data file acquired by the measuring device from the measuring device, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device and the network in the information processing system.

[0008] In one embodiment, the control unit may search for the metadata in the database based on a search keyword input by a user using a terminal device.

[0009] This allows a user to access the information processing device using a terminal device and efficiently search for a desired measurement data file via the metadata. In the information processing system, the measuring instrument generates metadata and transmits it to the information processing device, and the terminal device provides search keywords for measurement data files as binary files to the information processing device. This allows the information processing system to efficiently search for measurement data files without placing a heavy load on the network and the information processing device.

[0010] In one embodiment, the control unit may cause the terminal device to display the identification information included in the metadata as a search result, so that a user can check the identification information displayed by the terminal device as a search result and easily access the measurement data file based on the identification information.

[0011] In one embodiment, the identification information may include an identifier of the measuring device and a file path of the measurement data file in the measuring device, whereby a user can check the identification information displayed by a terminal device as a search result and easily access the measurement data file based on the identifier of the measuring device and the file path of the measurement data file in the measuring device.

[0012] In one embodiment of the information processing device, the metadata may further include, in addition to the identification information, measurement information related to the measurement process performed by the measuring device on the measurement target. This allows a user to easily extract the identification information associated with the search keyword from the database in the information processing device by inputting the measurement information as a search keyword into the terminal device. Therefore, the user can easily search for a specific measurement data file stored in the measuring device using the search keyword via the metadata stored in the information processing device.

[0013] An information processing system according to some embodiments includes any of the information processing devices described above, and the measuring instrument that generates the measurement data file by executing a measurement process on a measurement object.

[0014] This makes it possible to reduce the load caused by data communication. For example, the information processing device acquires metadata associated with a measurement data file acquired by the measuring device from the measuring device, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device and the network in the information processing system.

[0015] An information processing method according to some embodiments is an information processing method executed by an information processing device communicatively connected to a measuring device, and includes acquiring metadata from the measuring device associated with a measurement data file acquired by the measuring device, and storing the metadata in a database used to search for a specific measurement data file stored in the measuring device.

[0016] This makes it possible to reduce the load caused by data communication. For example, the information processing device acquires metadata associated with a measurement data file acquired by the measuring device from the measuring device, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device and the network in the information processing system.

[0017] A program according to some embodiments causes an information processing device communicatively connected to a measuring device to perform operations including acquiring metadata from the measuring device that is associated with a measurement data file acquired by the measuring device, and storing the metadata in a database used to search for a specific measurement data file stored in the measuring device.

[0018] This makes it possible to reduce the load caused by data communication. For example, the information processing device acquires metadata associated with a measurement data file acquired by the measuring device from the measuring device, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device and the network in the information processing system.

[0019] A measuring instrument in some embodiments is communicatively connected to an information processing device and includes a control unit, which generates a measurement data file by performing a measurement process on a measurement object, generates metadata associated with the measurement data file, and provides the metadata to the information processing device.

[0020] This makes it possible to reduce the load caused by data communication. For example, the information processing device acquires metadata associated with a measurement data file acquired by the measuring device from the measuring device, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device and the network in the information processing system.

[0021] The measuring device in one embodiment may further include a storage unit, and the control unit may store the measurement data file in the storage unit. This allows the measurement data file to be managed by the measuring device, not the information processing device. Therefore, the measuring device does not need to transmit the measurement data file itself to the information processing device. As a result, even if the file size of the measurement data file is large, the load on the information processing device and the network in the information processing system is reduced. Effect of the Invention

[0022] According to an information processing device, an information processing system, an information processing method, a program, and a measuring instrument according to an embodiment of the present disclosure, it is possible to reduce the load caused by data communication. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a block diagram showing a schematic configuration of the information processing device in FIG.

[Figure 4] FIG. 2 is a block diagram showing a schematic configuration of the terminal device of FIG. [Diagram 5] 1. FIG. 4 is a sequence diagram illustrating an example of an information processing method executed by the information processing system of FIG. [Figure 6] 2 is a diagram for explaining an example of processing by the information processing device of FIG. 1; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The background and problems of the prior art will now be described in more detail.

[0025] In the prior art, in an information processing system in which a measuring device and a server are connected to be able to communicate with each other, measurement data files are transmitted from the measuring device to the server and centrally managed by the server. A user accesses the server using a terminal device that the user uses, and searches for a desired measurement data file from among multiple measurement data files stored in the server.

[0026] In conventional technology, a server centrally manages measurement data files, so the measuring instrument needs to transmit the measurement data file to the server. In recent years, the file size of measurement data files has tended to become larger, and transmitting such measurement data files to the server by the measuring instrument increases the load on the network and the server.

[0027] In addition, measurement data files are often binary files and do not have search keywords for searching measurement data files, so users have no option but to search by file name and save date and time, making it difficult to efficiently search for measurement data files.

[0028] The conventional technology described in Patent Document 1 uses a means for searching by adding additional information to a file name. However, in commonly used OSs (Operating Systems), an upper limit is set on the length of a file name, so there is also an upper limit on the amount of additional information that can be added to a file name. Therefore, in the above means described in Patent Document 1, only limited information such as lot numbers is used as a search keyword, making it difficult to use a variety of search keywords.

[0029] In order to solve the above problems, the present disclosure aims to provide an information processing device, an information processing system, an information processing method, a program, and a measuring instrument that can reduce the load caused by data communication. For example, the present disclosure aims to provide an information processing device, an information processing system, an information processing method, a program, and a measuring instrument that allow a user to efficiently search for a desired measurement data file without placing a heavy load on a network, a server, etc.

[0060] Fig. 5 is a sequence diagram for explaining an example of an information processing method executed by the information processing system 1 of Fig. 1. With reference to Fig. 5, an example of the information processing method executed by the information processing system 1 of Fig. 1 will be mainly explained.

[0061] In step S101, control unit 25 of measuring device 20 generates a measurement data file by executing a measurement process on the measurement object.

[0062] In step S102, control unit 25 of measuring device 20 stores in memory unit 22 of measuring device 20 the measurement data file generated in step S101.

[0063] In step S103, control unit 25 of measuring instrument 20 generates metadata to be associated with the measurement data file generated in step S101. At this time, control unit 25 may store the generated metadata in memory unit 22 together with the measurement data file in a state where the metadata is associated with the measurement data file.

[0064] For example, control unit 25 acquires the serial number of measuring device 20, which was stored in advance as information in storage unit 22 when measuring device 20 was manufactured, by referencing storage unit 22. For example, control unit 25 acquires the host name of measuring device 20, which was set when measuring device 20 was connected to the local network for the first time and which was stored in advance as information in storage unit 22, by referencing storage unit 22.

[0065] For example, each time a measurement data file is generated in measuring instrument 20, control unit 25 acquires the file path of the measurement data file that is similarly stored in memory unit 22 in association with the measurement data file, by referring to memory unit 22. For example, control unit 25 acquires measurement information that is input by the user of measuring instrument 20 using input unit 23 and that is similarly stored in memory unit 22 in association with the measurement data file, by referring to memory unit 22.

[0066] As described above, the control unit 25 acquires necessary information based on the storage unit 22 and the input unit 23, and thereby generates metadata to be associated with the measurement data file generated in step S101.

[0067] In step S104, control unit 25 of measuring instrument 20 provides the metadata generated in step S103 to information processing device 10. For example, control unit 25 transmits the metadata generated in step S103 to information processing device 10 via communication unit 21 of measuring instrument 20 and network 40. Control unit 13 of information processing device 10 receives the metadata generated by measuring instrument 20 in step S103 from measuring instrument 20 via network 40 and communication unit 11.

[0068] The metadata provision process in step S104 may be performed each time a measurement data file is generated in step S101, or may be performed periodically or non-periodically for multiple measurement data files at once. In this manner, control unit 13 of information processing device 10 acquires from measuring instrument 20 metadata associated with the measurement data file acquired by measuring instrument 20.

[0069] In step S105, control unit 13 of information processing device 10 stores the metadata acquired in step S104 in a database used to search for a predetermined measurement data file stored in measuring instrument 20. For example, control unit 13 stores the metadata acquired in step S104 in storage unit 12.

[0070] In step S106, the control unit 13 of the information processing device 10 acquires a search request for metadata based on an input operation by the user using the input unit 33 of the terminal device 30. For example, the user accesses the information processing device 10 while operating the input unit 33 of the terminal device 30, and inputs a search keyword related to information included in the metadata.

[0071] In step S107, the control unit 13 of the information processing device 10 searches for metadata stored in the storage unit 12 in accordance with the search request acquired in step S106. For example, the control unit 13 searches for metadata in a database based on a search keyword input by the user using the terminal device 30.

[0072] In step S108, the control unit 13 of the information processing device 10 causes the terminal device 30 to display the identification information included in the metadata as the search result of the search processing in step S107. At this time, the control unit 13 of the information processing device 10 may also cause the terminal device 30 to display the measurement information associated with the identification information as the search result of the search processing in step S107, in addition to the identification information. The control unit 35 of the terminal device 30 causes the display of the output unit 34 to display the identification information and the like included in the metadata as the search result of the search processing by the information processing device 10.

[0073] As described above, in information processing system 1, measuring instrument 20 stores a measurement data file that it has generated in storage unit 22 of measuring instrument 20. Meanwhile, information processing device 10, which is communicatively connected to measuring instrument 20, manages metadata transmitted from measuring instrument 20. Information processing device 10 uniquely identifies the measurement data file based on a unique identifier that identifies measuring instrument 20 and a file path in measuring instrument 20 that saves the measurement data file. Information processing device 10 manages the measurement information together as information accompanying the measurement data file, making it possible to use the measurement information as a search keyword.

[0074] A user accesses the information processing device 10 using the terminal device 30 that the user uses, inputs a search keyword via the input unit 33 of the terminal device 30, and searches for a target measurement data file via metadata. The information processing device 10 displays, as a search result, the identification information of the measuring device 20 that matches the search criteria input by the user on the output unit 34 of the terminal device 30. Based on the identification information displayed on the output unit 34 of the terminal device 30, the user can access a measurement data file that is stored in a specific measuring device 20 with a specific file path.

[0075] Fig. 6 is a diagram for explaining an example of processing by the information processing device 10 in Fig. 1. Fig. 6 shows an example of metadata on a database stored in the storage unit 12 of the information processing device 10 in step S105 in Fig. 5.

[0076] As shown in Fig. 6, the metadata associates information with each measurement data file generated by the measuring instrument 20. The "measurement data file" in Fig. 6 merely conceptually indicates the measurement data file with which the metadata is associated, and does not mean that the data content of the measurement data file itself is included in the metadata. The metadata is composed solely on the basis of identification information, including an identifier and a file path, and measurement information.

[0077] For example, in the metadata, the identifier of the corresponding measuring instrument 20 is associated as information with each measurement data file. In the metadata, the file path of the measurement data file in the measuring instrument 20 is associated as information with each measurement data file. As described above, in the metadata, the corresponding identification information is associated with each measurement data file. In addition, in the metadata, the corresponding measurement information is associated with each measurement data file.

[0078] According to the embodiment described above, it is possible to reduce the load caused by data communication. For example, the information processing device 10 acquires metadata associated with a measurement data file acquired by the measurement device 20 from the measurement device 20, and stores the metadata in a database used to search for a specific measurement data file. This allows the information processing device 10 to process only the metadata of the measurement data file without directly managing the measurement data file. Therefore, the measurement device 20 does not need to transmit the measurement data file itself to the information processing device 10. As a result, even if the file size of the measurement data file is large, only metadata having a smaller data volume compared to the measurement data file is transmitted, thereby reducing the load on the information processing device 10 and the network 40 in the information processing system 1.

[0079] The information processing device 10 searches for metadata in a database based on a search keyword input by a user using the terminal device 30. This allows a user to access the information processing device 10 using the terminal device 30 and efficiently search for a target measurement data file via the metadata. In the information processing system 1, the measuring instrument 20 generates metadata and transmits it to the information processing device 10, and the terminal device 30 provides the information processing device 10 with search keywords for measurement data files as binary files. This allows the information processing system 1 to efficiently search for measurement data files without placing a heavy load on the network 40 and the information processing device 10.

[0080] The information processing device 10 displays the identification information included in the metadata as a search result on the terminal device 30. This allows the user to check the identification information displayed by the terminal device 30 as a search result and easily access the measurement data file based on the identification information.

[0081] The identification information includes the identifier of the measuring device 20 and the file path of the measurement data file in the measuring device 20. This allows the user to check the identification information displayed by the terminal device 30 as a search result, and easily access the measurement data file based on the identifier of the measuring device 20 and the file path of the measurement data file in the measuring device 20.

[0082] In addition to the identification information, the metadata further includes measurement information related to the measurement process performed on the measurement target by the measuring instrument 20. This allows the user to input the measurement information as a search keyword into the terminal device 30, and easily extract the identification information associated with the search keyword from the database in the information processing device 10. Therefore, the user can easily search for a specific measurement data file stored in the measuring instrument 20 using the search keyword via the metadata stored in the information processing device 10.

[0083] Measuring instrument 20 stores the measurement data file in storage unit 22. As a result, the measurement data file is managed by measuring instrument 20, not by information processing device 10. Therefore, measuring instrument 20 does not need to transmit the measurement data file itself to information processing device 10. As a result, even if the file size of the measurement data file is large, the load on information processing device 10 and network 40 in information processing system 1 is reduced.

[0084] Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art can make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present disclosure.

[0085] For example, a general-purpose electronic device such as a smartphone or a computer can be configured to function as the information processing device 10 according to the embodiment described above. Specifically, a program describing the processing contents for realizing each function of the information processing device 10 according to the embodiment is stored in the memory of the electronic device, and the program is read and executed by the processor of the electronic device. Therefore, the present disclosure can also be realized as a program executable by a processor.

[0086] Alternatively, the present disclosure may be realized as a non-transitory computer-readable medium storing a program executable by one or more processors to cause the information processing device 10 according to an embodiment to execute each function. It should be understood that these are also included in the scope of the present disclosure.

[0087] For example, at least a portion of the processing operations executed in the information processing device 10 in the embodiment described above may be executed in the measuring device 20 or the terminal device 30.

[0088] In the above embodiment, the information processing device 10 searches for metadata in a database based on a search keyword input by a user using the terminal device 30. However, the present invention is not limited to this. The search method used in the information processing system 1 may include any other method.

[0089] In the above embodiment, the measurement information is used as a search keyword, but this is not limiting. When searching for metadata in step S107 of Fig. 5, at least one of the identifier of the measuring device 20 and the file path of the measurement data file in the measuring device 20 may be used as a search keyword.

[0090] In the above embodiment, the information processing device 10 has been described as causing the terminal device 30 to display the identification information included in the metadata as a search result, but is not limited thereto. The information processing device 10 may cause the terminal device 30 to display the search result by any other display method. For example, the information processing device 10 may cause the terminal device 30 to display the measurement information as a search result in addition to the identification information.

[0091] In the above embodiment, the information processing device 10 has been described as outputting the search results in a visual manner using the output unit 34 of the terminal device 30, but is not limited thereto. The information processing device 10 may output the search results from the output unit 34 of the terminal device 30 in any manner other than the visual manner. For example, the information processing device 10 may output the search results in an auditory manner using the output unit 34 of the terminal device 30.

[0092] In the above embodiment, the identification information has been described as including an identifier of the measurement device 20 and a file path of the measurement data file in the measurement device 20, but is not limited to this. The identification information may include any other information capable of identifying the measurement data file stored in the measurement device 20.

[0093] In the above embodiment, the metadata includes, in addition to the identification information, measurement information related to the measurement process performed by the measuring device 20 on the measurement target. However, the metadata is not limited to this. The metadata may include any other information that can be used as a search keyword.

[0094] In the above embodiment, the information processing system 1 is described as including the information processing device 10, the measuring device 20, and the terminal device 30, but is not limited to this. The information processing system 1 may not include the terminal device 30, and may have only the information processing device 10 and the measuring device 20 that generates a measurement data file by executing a measurement process on a measurement target.

[0095] In the above embodiment, the measurement device 20 has been described as storing the measurement data file in the storage unit 22 of the measurement device 20, but this is not intended to be limiting. The measurement device 20 may store the measurement data file in any other storage device different from the measurement device 20 in addition to or instead of the storage unit 22 of the measurement device 20.

[0096] In the above embodiment, a measurement data file is exemplified as a search target in the information processing system 1, but the search target is not limited to this. The information processing system 1 can similarly improve the efficiency of file searches for any other binary files.

[0097] The information processing system 1 does not depend on a network configuration. Therefore, in the information processing system 1, for example, it is possible to implement the server function provided by the information processing device 10 on the cloud. This makes it possible to search for measurement data files in a measuring device 20 installed in a remote location from a terminal device 30 used by a user.

[0098] In the above embodiment, the measuring instrument 20 has been described as including, for example, a waveform measuring instrument and an optical measuring instrument, but is not limited thereto.
