Description

[Technical field]

[0001] The present invention relates to a technique that is effective for non-destructive testing of structures such as bridges, concrete structures, road accessories, and tile structures. [Background technology]

[0002] Conventionally, hammering tests using inspection hammers have been conducted as part of non-destructive testing of structures such as bridges, concrete structures, road accessories, tile structures, etc. In general, inspectors use the inspection hammer to diagnose structures (see Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] Shinya Kitagawa and 2 others, “Characteristics Obtained from Inspection Hammers Used for Hammering Inspection”, [online], September 2014, 69th Annual Conference of the Japan Society of Civil Engineers, [Retrieved October 23, 2023], Internet<URL : http: / / library.jsce.or.jp / jsce / open / 00035 / 2014 / 69-05 / 69-05-0083.pdf> Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional non-destructive testing requires inspection by inspectors based on their own experience. This non-destructive testing is performed based on the inspectors' judgment based on their experience, making it difficult to make quantitative judgments. In addition, if the inspector is inexperienced, it is difficult for him or her to make a correct judgment. Additionally, the analytical work carried out when an inspection hammer is struck against a structure also requires standardization rather than personalization. Therefore, the present inventors focused on a mechanism for standardizing analysis work in non-destructive testing.

[0005] An object of the present invention is to provide an anomaly analysis system, an anomaly analysis method, and a program that are capable of performing an anomaly analysis of a structure without being dependent on a specific individual. [Means for solving the problem]

As a result, the abnormality analysis system 1 performs the tapping work on the structure and analyzes the vibration data, and it becomes possible to perform an abnormality analysis of the structure without relying on a personal analysis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a detailed description will be given of an embodiment of the present invention with reference to the accompanying drawings. In the following drawings, the same elements are designated by the same numbers or symbols throughout the description of the embodiment.

[0012] [Outline of Anomaly Analysis System 1] Fig. 1 is a schematic diagram for explaining an overview of an anomaly analysis system 1. Components of the anomaly analysis system 1 will be explained with reference to Fig. 1. The abnormality analysis system 1 is a system including at least a tapping device 2 that performs a tapping inspection of a structure, and a computer 10 that is communicatively connected to the tapping device 2. The tapping device 2 is a device that taps a structure with a certain amount of force when conducting a tapping inspection of the structure, and acquires and transmits vibration data generated during the tapping. This tapping device 2 taps the structure instead of an inspection hammer. The computer 10 has a server function and may be realized, for example, by a single computer, or may be realized by a plurality of computers, such as a cloud computer. In this specification, a cloud computer may refer to either a scalable use of any computer to perform a specific function, or a computer that includes multiple functional modules to realize a system, the functions of which can be freely combined.

[0013] An overview of the processing steps performed by the anomaly analysis system 1 when performing non-destructive testing of a structure will be described.

[0014] The tapping device 2 taps the structure with a certain amount of force (step S1). The striking device 2 strikes the structure instantaneously with a constant force by rotating an internal gear.

[0015] The tapping device 2 acquires vibration data when the structure is tapped (step S2). When the tapping device 2 taps on a structure, it obtains, as vibration data, a waveform having a predetermined frequency according to the state of the structure.

[0016] The tapping device 2 transmits the acquired vibration data to the computer 10 (step S3), and the computer 10 receives this vibration data (step S4).

[0017] The computer 10 analyzes the structure based on the received vibration data (step S5). The computer 10 analyzes the structure using vibration data of the structure in a preset abnormal state, or a learning model generated based on the learning results of vibration data of the structure in a past abnormal state, etc.

[0018] The above is an overview of the processing steps of the anomaly analysis system 1. According to the present anomaly analysis system 1, it becomes possible to perform an anomaly analysis of a structure without relying on a specific person.

[0019] [Device configuration] 2 is a block diagram showing the configuration of the anomaly analysis system 1. The device configuration of the anomaly analysis system 1 will be described with reference to FIG. The abnormality analysis system 1 is a system that includes at least a tapping device 2 that performs a tapping inspection of a structure, and a computer 10 that is communicatively connected to the tapping device 2. The abnormality analysis system 1 is a system in which a computer 10 is connected to a tapping device 2 so as to be capable of data communication via a network 8 such as a public line network, wired communication, or wireless communication. The method of connecting the tapping device 2 and the computer 10 is not particularly limited. In addition, the abnormality analysis system 1 may include other terminals and devices in addition to the tapping device 2 and computer 10 described above, and the number, type, and functions of these are not particularly limited and can be designed as appropriate.

[0020] The tapping device 2 is a device that performs a tapping inspection of a structure. The tapping device 2 plays the role of an inspection hammer in non-destructive inspection of a structure. The tapping device 2 includes a tapping unit 3 that taps the structure with a certain amount of force, an acquisition unit 4 that acquires vibration data when the structure is tapped, and a transmission unit 5 that transmits the acquired vibration data to a computer 10. The hitting device 2 has a handgun type shape (see FIG. 3). The hitting device 2 has one or more internal gears, and the rotation of the internal gears instantaneously hits the structure with a constant amount of force. The hitting device 2 further has an elastic body (such as a spring) that expands and contracts as the internal gears rotate, and contracts after the structure is hit by the hitting unit 3. The hitting device 2 hits the structure at constant intervals and with a constant amount of force by hitting the structure with the rotation of the internal gear and by the expansion and contraction of the elastic body. The hitting device 2 also has an expandable item (such as a pole with a predetermined length) and a detachable mechanism (see FIG. 4). The shape of the hitting device 2 is not limited to a handgun type, and may be other shapes. The number, size, type, etc. of the internal gears and elastic bodies are not particularly limited, and can be designed appropriately. Similarly, the article is not particularly limited, and can be designed appropriately.

[0021] The tapping device 2 will be described with reference to Fig. 3. Fig. 3(a) is a diagram showing a typical appearance of the tapping device 2. Fig. 3(b) is a diagram showing a typical internal structure of the tapping device 2. Fig. 3(c) is a diagram showing a typical structure of the tapping section. The tapping device 2 has an appearance of a handgun type device. When an inspector pulls a trigger 20 of the tapping device 2, a protrusion 21 taps a structure. The protrusion 21 has a hemispherical tip, and its bottom surface is attached to a tapping member 33. The tip of the protrusion 21 is rounded so as not to damage the structure. The tapping device 2 is also provided with an attachment part 22 for attaching a pole 42, which will be described later. The shape of the protrusion 21 is not limited to the above-mentioned example. The tapping device 2 has a tapping unit 30 therein. The tapping unit 30 has a plurality of internal gears 31 (a first gear 31a, a second gear 31b, and a third gear 31c), a motor 32 that rotates the internal gear 31 in accordance with the movement of the trigger 20, a tapping member 33 to which the bottom surface of the protrusion 21 is attached, a spring 34 that is connected to the end of the tapping member 33 on the opposite side to the protrusion 21, and a support member 35 that supports the spring 34. The tapping member 33 has a meshing portion 330 formed on the internal gear 31 side, and meshes with the first gear 31a through the meshing portion 330. In the internal gear 31, the first gear 31a meshes with the second gear 31b, and the second gear 31b meshes with the third gear 31c. When an inspector pulls the trigger 20, the motor 32 rotates the internal gear 31 (the third gear 31c rotates, the second gear 31b rotates in accordance with the rotation of the third gear 31c, and the first gear 31a rotates in accordance with the rotation of the second gear 31b). In accordance with the rotation of the first gear 31a, the engaging portion 330 pushes out the striking member 33, and the protrusion 21 strikes the structure. After the protrusion 21 strikes the structure, the spring 34 pulled by the striking member 33 tries to contract in an attempt to return to its original shape, and as a result, the striking member 33 moves toward the support member 35. After the striking member 33 moves toward the support member 35, the striking member 33 is pushed out by the meshing portion 330 in accordance with the rotation of the first gear 31a again due to the rotation of the internal gear 31 (rotation of the first gear 31a), and the protrusion 21 strikes the structure. By repeating this, the striking unit 30 strikes the structure instantaneously at a constant interval and with a constant force due to the rotation of the internal gear 31. If an electrical force such as a solenoid structure is used to strike a structure, the striking tool will not bounce back and will stop when it hits the structure, making it impossible to obtain the vibrations generated in the structure. However, by striking the structure using physical forces such as the internal gear 31 and spring 34, the protrusion 21 bounces back the moment it hits the structure and does not stop vibrating, making it easier to accurately obtain the vibrations generated in the structure. The internal structure of the tapping unit 30 is not limited to that shown in the figure. For example, the number and shape of the internal gears 31 are not limited to those shown in the figure, and can be designed as appropriate. Similarly, the shapes, numbers, functions, etc. of the other parts can be designed as appropriate.

[0022] The stretchable article and detachable mechanism of the hitting device 2 will be described with reference to Fig. 4. Fig. 4(a) is a schematic diagram showing the state when the hitting device 2 is attached to the stretchable article. Fig. 4(b) is an enlarged view of the hitting device 2 in Fig. 4(a). The tapping device 2 is detachably attached to one end of a telescopic pole 41. An inspector 40 uses the pole 41 to perform non-destructive inspection of an electric light 42 at a high place. A rotatable rotating part 43 is attached to the tip of the pole 41. Furthermore, the rotating part 43 is provided with a connecting part 44 for connecting with the tapping device 2. The connecting part 44 is detachable from the mounting part 22. The mounting part 22 may have, for example, a groove into which the connecting part 44 can be fitted, and the connecting part may be detachably fitted into the groove, or the mounting part 22 and the connecting part 44 may be engaged with each other, or may have another structure. The rotating part 43 and the connecting part 44 are connected by a support rod 45. When the tapping device 2 is moved vertically or horizontally, the connecting part 44 and the support rod 45 move the rotating part 43 in accordance with this movement. The connecting part 44 may be a mechanism included in the tapping device 2, or may be a mechanism included in the pole 41. When the tapping device 2 has the connecting part 44, it is sufficient that the connecting part 44 is detachably attached to the rotating part 43 and the support rod 45. When the pole 41 is attached to the tapping device 2, the trigger 20 may be pulled by a device provided on the pole 41, or the trigger 20 may be maintained in a pulled state (such as by holding the trigger 20 and maintaining the pulled state).

[0023] Returning to FIG. 2, the configuration of the computer 10 will be described. The computer 10 has a server function and may be realized, for example, by one computer, or may be realized by multiple computers such as a cloud computer. The computer 10 may also be a terminal device such as a mobile terminal (such as a mobile phone, smartphone, or tablet terminal), a personal computer, or a laptop computer. The computer 10 has a control unit such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and has a communication unit such as a device for enabling communication with other terminals and devices, and a receiving unit 11 for receiving vibration data. The computer 10 includes a storage unit such as a hard disk, a semiconductor memory, a recording medium, a data storage unit such as a memory card, etc. as a storage unit. The computer 10 includes, as a processing unit, various devices that execute various processes, an analysis unit 12 that analyzes the structure based on the received vibration data, and the like.

[0024] In the computer 10, the control unit loads a predetermined program, and thereby cooperates with the communication unit to realize a receiving module, a vibration data acquisition module, and a status data acquisition module. In addition, in the computer 10, the control unit reads a predetermined program and cooperates with the storage unit to realize a storage module. In addition, in the computer 10, the control unit reads a predetermined program and cooperates with the processing unit to realize an analysis module, a display module, a determination module, a learning module, and a generation module.

[0025] Hereinafter, each process executed by the anomaly analysis system 1 will be described together with the process executed by each of the modules described above. In this specification, each module may execute its processing contents as its own function, or may execute its processing contents via a predetermined application.

[0026] [Transmission process executed by the tapping device 2] The transmission process executed by the tapping device 2 will be described with reference to Fig. 5. This figure shows a flowchart of the transmission process executed by the tapping device 2. This transmission process shows details of a tapping process (step S1) executed by the tapping device 2 to tap a structure with a certain amount of force, an acquisition process (step S2) to acquire vibration data when the structure is tapped, and a transmission process (step S3) to transmit the acquired vibration data to the computer 10.

[0027] The tapping unit 3 taps the structure with a constant force (step S10). The striking unit 3 strikes the structure instantaneously with a constant force by the rotation of the internal gear 31.

[0028] The acquisition unit 4 acquires vibration data when a structure is struck (step S11). The vibration data is a waveform according to the state of the structure (see FIG. 6). The vibration data is a digitalized version of the change in frequency detected by the vibration sensor of the tapping device 2. When tapping, the vibration sensor detects different frequencies depending on whether the structure is in a normal state or in an abnormal state such as floating or peeling. The acquisition unit 4 acquires vibration data using a vibration sensor provided in the tapping device 2 when the tapping unit 3 taps the structure while the inspector is pulling the trigger 20.

[0029] Vibration data will be described with reference to Fig. 6. This figure is a diagram that shows a schematic example of vibration data. In this figure, vibration data 50 is shown. This vibration data 50 is a graph with time on the horizontal axis and frequency on the vertical axis. The vibration data 50 shows the frequency detected when the object is struck. When the object is struck, a change occurs in the frequency, and each peak 51 corresponds to this change. Each peak 51 is analyzed during the analysis process by the computer 10, which will be described later.

[0030] Returning to FIG. 5, the rest of the transmission process will be described. The transmitting unit 5 transmits the acquired vibration data to the computer 10 (step S12). The transmission unit 5 links the acquired vibration data to the identifiers of the structure (site name, management number, inspector identifiers (name, ID, management number, etc.)) and transmits the data directly to the computer 10. The transmission unit 5 may be configured to transmit the acquired vibration data to the computer 10 via an external storage computer such as a cloud computer. In this case, the transmission unit 5 transmits the acquired vibration data to an external storage computer such as a cloud computer. The external storage computer receives and stores the vibration data. The external storage computer links the received vibration data to an identifier of the structure and transmits the data to the computer 10.

[0031] This completes the transmission process.

[0032] [Analysis process performed by computer 10] The analysis process executed by the computer 10 will be described with reference to Fig. 7. This figure is a flowchart showing the analysis process executed by the computer 10. This analysis process shows details of a reception process (step S4) for receiving vibration data and an analysis process (step S5) for analyzing a structure based on the received vibration data.

[0033] The receiving module receives the vibration data (step S20). The receiving module receives the vibration data transmitted by the tapping device 2 through the transmission process.

[0034] The analysis module analyzes the structure based on the received vibration data (step S21). The analysis module analyzes the structure based on each peak of the waveform in this vibration data. The analysis method executed by the analysis module may use a learning model generated as a result of a learning process described later, or may be another method such as a comparison with a waveform in a preset abnormal state. The process when the analysis module analyzes the structure using the learning model will be described in the learning process described later. In this process, a case will be described in which the analysis module compares the waveform in the currently received vibration data with a waveform indicating a preset abnormal state. The analysis module extracts each peak of the waveform in the received vibration data from the vibration data and identifies the frequency of each peak. The analysis module compares the frequency of each identified peak with the frequency of a waveform in a preset abnormal state and determines whether it matches or is close to the frequency of the waveform in the abnormal state. The frequency of the waveform in the preset abnormal state is linked to the specific content of the abnormality occurring in the structure (floating, peeling, etc.). The frequency of the waveform in the abnormal state may be set for each content of the abnormality, or may be set to a frequency corresponding to the content of the abnormality based on the inspection content according to the structure to be struck, or may be other than that. If the analysis module determines that there is no frequency of the identified peaks that matches or is close to the frequency of the waveform in the abnormal state, it determines that no abnormality has occurred in the structure from which the vibration data was obtained. When the analysis module determines that one of the identified peak frequencies matches or is close to the frequency of the waveform in an abnormal state, it determines that an abnormality has occurred in the structure from which the vibration data was acquired. Here, the analysis module also identifies the content of the abnormality in the structure from which the vibration data was acquired based on the content of the abnormality linked to the matching or close frequency of the waveform in an abnormal state.

[0035] The display module displays the analysis results of the structure (step S22). If no abnormality has occurred as a result of the analysis of the structure, the display module displays a normal notification indicating that no abnormality has occurred on its own display unit, etc. This normal notification includes the structure's identifier, the inspection date and time, the inspector's identifier, a message (text, icon, etc.) indicating that no abnormality has occurred in the structure, etc. The content of the normal notification may be designed as appropriate. The method of displaying this normal notification may be a specified UI (User Interface), email, voice, etc., and may be designed as appropriate. If an abnormality is found as a result of the analysis of the structure, the display module displays an abnormality notification indicating the occurrence of the abnormality on its own display unit or the like. This abnormality notification includes the structure's identifier, the inspection date and time, the inspector's identifier, a message (text, icon, etc.) indicating that an abnormality has occurred in the structure, the details of the abnormality, etc. The contents of the abnormality notification may be designed as appropriate. The method of displaying this abnormality notification may be a specified UI (User Interface), email, voice, etc., and may be designed as appropriate.

[0036] The storage module stores the received vibration data (step S23). The storage module may store only the received vibration data, or may store the vibration data in association with the analysis results of the vibration data.

[0037] The above is the analysis process. The computer 10 may be configured to transmit the analysis result of the current structure to an external storage computer. In this case, the external storage computer stores the analysis result in association with the vibration data when the structure is struck.

[0038] [Learning process executed by computer 10] The learning process executed by the computer 10 will be described with reference to Fig. 8. The figure shows a flowchart of the learning process executed by the computer 10.

[0039] The vibration data acquisition module acquires past vibration data (step S30). The past vibration data acquired by the vibration data acquisition module may be vibration data received by the above-mentioned analysis process, may be vibration data stored in an external storage computer, or may be other vibration data. When the vibration data acquisition module acquires vibration data received by the analysis process, it acquires the vibration data received by the analysis process and stored by the storage module. When the vibration data acquisition module acquires vibration data stored in the external storage computer, it transmits a transmission request for the vibration data to the external storage computer. The external storage computer transmits the vibration data based on this transmission request. The vibration data acquisition module receives this vibration data and acquires past vibration data. Even when the vibration data acquisition module acquires vibration data other than the above, it is sufficient to perform the necessary processing as appropriate and acquire the past vibration data, as in the above example.

[0040] The state data acquisition module acquires the state of the structure when the past vibration data was acquired (step S31). The state data acquisition module acquires, as state data, the state of the structure when the tapping device 2 acquired the past vibration data. The status data acquired by the status data acquisition module may be based on analysis results linked to the acquired vibration data, or it may be based on the actual status of the structure as determined by an inspector or the like separately from the analysis results, or it may be something else. The state data acquisition module acquires the state of the structure in the analysis results linked to the acquired past vibration data (either a normal or abnormal state, and in the case of an abnormality, the details of the abnormality). The processes of steps S30 and S31 may be performed together with the above-mentioned analysis process. In this case, the processes of steps S30 and S31 may be omitted, and the vibration data received during the analysis process and the analysis results of the vibration data may be used in the process described later.

[0041] The determination module determines whether the acquired state of the structure is abnormal or not (step S32). The determination module determines the state of the structure based on whether the acquired state of the structure is normal or abnormal. When the determination module determines that the acquired state of the structure is normal (step S32 NO), the computer 10 ends this learning process.

[0042] On the other hand, if the determination module determines that the acquired state of the structure is abnormal (YES in step S32), the learning module learns the received past vibration data and the actual abnormal state of the structure (step S33). Examples of learning methods include machine learning using supervised learning, unsupervised learning, reinforcement learning, etc., and deep learning using convolutional neural networks, recurrent neural networks, long-short-term memories, etc. In this embodiment, machine learning using supervised learning will be described as an example. The learning module performs learning using the frequency of the waveform in the received past vibration data, the fact that this waveform is abnormal, and the details of the abnormality as teacher data. The learning method is not limited to the above example, and can be designed as appropriate. Similarly, the algorithm used for learning can be designed as appropriate.

[0043] The generation module generates a learning model based on the learning result (step S34). The generation module generates a learning model for the vibration data using a predetermined algorithm based on the learning result. The algorithm used to generate the learning model can be designed as appropriate.

[0044] The storage module stores the generated learning model (step S35).

[0045] The above is the learning process. The computer 10 can also be configured to execute the process of step S21 described above using a learning model generated by the learning process. This case will be described. The analysis module analyzes the received vibration data based on the generated learning model. The analysis module extracts each peak of the waveform in the received vibration data from the vibration data and identifies the frequency of each peak. The analysis module compares the frequency of each identified peak with the frequency of the waveform in the learning model and determines whether they match or are close. If the analysis module determines that they match or are close, it analyzes that the structure from which the received vibration data was obtained is in an abnormal state, and if it determines that they do not match or are close, it analyzes that the structure from which the received vibration data was obtained is in a normal state. When the analysis module determines that the structure is in an abnormal state, in addition to being abnormal, it also analyzes the content of the abnormality.

[0046] Although the above-mentioned processes are described as separate processes, the anomaly analysis system 1 can be configured to execute a combination of some or all of the above-mentioned processes.

[0047] The above-mentioned means and functions are realized by a computer (including a CPU, an information processing device, and various terminals) reading and executing a predetermined program. The program may be provided, for example, from a computer via a network (Software as a Service (SaaS)) or as a cloud service. The program may also be provided in a form recorded on a computer-readable recording medium. In this case, the computer reads the program from the recording medium, transfers it to an internal or external recording device, records it, and executes it. The program may also be recorded in advance on a recording device (recording medium) and provided from the recording device to the computer via a communication line.
