DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The principles of the present disclosure are described with reference to some exemplary embodiments. It should be understood that these embodiments are set forth for illustrative purposes only, to aid those skilled in the art in understanding and practicing the present disclosure, without implying any limitation on the scope of the present disclosure. The disclosure described herein may be implemented in various ways other than those described below. In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0013] (Embodiment 1) <Configuration> The configuration of an information processing device 10 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the information processing device 10 according to an embodiment. The information processing device 10 has an acquisition unit 11, a control unit 12, and an output unit 13. Each of these units may be realized by cooperation between one or more programs installed in the information processing device 10 and hardware such as a processor 101 and a memory 102 of the information processing device 10.

[0014] The acquisition unit 11 acquires various pieces of information from a storage unit in the information processing device 10 or an external device. The acquisition unit 11 acquires, for example, information indicating a first location, information indicating a second location, first measurement data measured at the first location, and second measurement data measured at the second location.

[0015] The control unit 12 determines the equipment to be inspected based on the data acquired by the acquisition unit 11. The output unit 13 outputs information based on the equipment determined by the control unit 12.

[0016] (Embodiment 2) Next, the configuration of the inspection system 1 according to the embodiment will be described with reference to FIG. <System configuration> FIG. 2 is a diagram showing a configuration example of an inspection system 1 according to an embodiment. In the example of FIG. 2, the inspection system 1 has an information processing device 10 and an optical fiber sensor 20. The inspection system 1 also has an inspection device 30A and an inspection device 30B (hereinafter, when there is no need to distinguish between them, they will also be simply referred to as "inspection device 30"). Note that the number of information processing devices 10, optical fiber sensors 20, and inspection devices 30 is not limited to the example of FIG. 2. Note that the technology disclosed herein can be used for the inspection (maintenance) of various facilities such as substations, plants, factories, offices, and logistics warehouses.

[0017] 2, the information processing device 10, the optical fiber sensor 20, and the inspection device 30 are connected so as to be able to communicate with each other via a network N. Examples of the network N include, for example, the Internet, a mobile communication system, a wireless LAN (Local Area Network), a short-range wireless communication such as BLE, a LAN, and a bus. Examples of the mobile communication system include, for example, a fifth-generation mobile communication system (5G), a fourth-generation mobile communication system (4G), a third-generation mobile communication system (3G), and the like.

[0018] The information processing device 10 may be, for example, a device such as a server, a cloud, a personal computer, or a smartphone. The information processing device 10 provides various services using abnormality detection of various equipment installed in a facility and an inspection device 30. For example, the information processing device 10 causes the inspection device 30 to inspect equipment in which an abnormality has occurred.

[0019] 2, the optical fiber cable of the optical fiber sensor 20 is laid along the periphery of the site of the facility. Note that the laying position of the optical fiber cable of the optical fiber sensor 20 is not limited to the example of FIG.

[0020] The optical fiber sensor 20 has an optical fiber cable 21 which is an information transmission medium. The optical fiber sensor 20 also has a sensing device 22 connected to one end of the optical fiber cable 21, and a termination device 23 connected to the other end of the optical fiber cable 21. The termination device 23 is a device that performs termination processing to suppress reflection of the sensing signal output from the sensing device 22.

[0021] The sensing device 22 outputs a pulse wave sensing signal to the optical fiber cable 21. Then, the sensing device 22 measures the reflected signals (return light) in response to the sensing signal from all positions on the optical fiber cable 21 in time series. When vibration or sound is applied to the optical fiber cable 21, or when the temperature changes, the light intensity of the return light changes. The sensing device 22 calculates the position in the optical fiber cable 21 where the vibration or sound is applied, based on the round-trip time from when the sensing signal is output to when the return light with the changed light intensity is observed.

[0022] The sensing device 22 simultaneously measures the vibration and sound applied at multiple points spaced apart by a predetermined distance (for example, 1 m). In addition, by outputting a sensing signal at a time interval at which the return light from the farthest end of the optical fiber cable 21 and the light of the sensing signal to be output next are not mixed, it is possible to measure the change over time (time transition) of the vibration and sound applied at each position. In addition, the optical fiber cable 21 may be installed at different heights at each point. This makes it possible to estimate the three-dimensional position of the location where the abnormality occurred.

[0023] By using the optical fiber sensor 20, the construction of the installation is easier than when, for example, multiple microphones or multiple vibration sensors are used. Furthermore, if an optical fiber cable 21 for communication has already been laid, the optical fiber cable 21 can be used in common for communication and for facility maintenance, eliminating the need for new installation construction. Furthermore, since no electricity flows through the optical fiber cable 21, it can be used in facilities where flammable gas may be present. Note that in the inspection system 1 according to the embodiment, at least one of multiple microphones and multiple vibration sensors may be used instead of or in addition to the optical fiber sensor 20.

[0024] The inspection device 30 is a device having sensors for inspecting various facilities such as substations, power plants, factories, and chemical plants. The inspection device 30 may have a function of performing inspection while autonomously moving around the periphery of the facility. In this case, the inspection device 30 may be, for example, an autonomous mobile robot that moves on the ground by wheels or legs. The inspection device 30 may also be, for example, a drone (unmanned aerial vehicle) or a balloon that moves by flying.

[0025] <Hardware configuration> Fig. 3 is a diagram showing an example of a hardware configuration of an information processing device 10 according to an embodiment. In the example of Fig. 3, the information processing device 10 (computer 100) includes a processor 101, a memory 102, and a communication interface 103. These units may be connected by a bus or the like. The memory 102 stores at least a part of a program 104. The communication interface 103 includes an interface required for communication with other network elements.

The processor 101 may include one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), and a processor based on a multi-core processor architecture, as a non-limiting example. The computer 100 may have multiple processors, such as application-specific integrated circuit chips that are time-slaved to a clock that synchronizes the main processor.

The functionality of the program modules may be combined or split between program modules as desired in various embodiments. The machine-executable instructions of the program modules may be executed in local or distributed devices. In a distributed device, the program modules may be located in both local and remote storage media.

[0029] The program codes for carrying out the methods of the present disclosure may be written in any combination of one or more programming languages. These program codes are provided to a processor or controller of a general purpose computer, a special purpose computer, or other programmable data processing apparatus. When the program codes are executed by the processor or controller, the functions / operations in the flowcharts and / or the block diagrams they implement are performed. The program codes are executed entirely on the machine, partly on the machine, as a stand-alone software package, partly on the machine and partly on a remote machine, or entirely on a remote machine or server.

[0030] The program can be stored and provided to the computer using various types of non-transitory computer-readable media. The non-transitory computer-readable media include various types of tangible recording media. Examples of the non-transitory computer-readable media include magnetic recording media, magneto-optical recording media, optical disk media, semiconductor memories, and the like. The magnetic recording media include, for example, flexible disks, magnetic tapes, hard disk drives, and the like. The magneto-optical recording media include, for example, magneto-optical disks, and the like.

Examples of the temporary computer-readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire or an optical fiber, or via a wireless communication path.

[0031] <Processing> Next, an example of processing of the information processing device 10 according to the embodiment will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a flowchart showing an example of processing of the information processing device 10 according to the embodiment. Fig. 5 is a diagram showing an example of a facility DB 501 according to the embodiment. Fig. 6 is a diagram showing an example of a type DB 601 according to the embodiment.

[0032] In step S1, the acquisition unit 11 of the information processing device 10 acquires measurement data of the transition of the amplitude (intensity) of vibration or sound measured at each predetermined position of the optical fiber cable 21 and information indicating each of the predetermined positions from the optical fiber sensor 20. The information indicating each of the predetermined positions may include, for example, information on the latitude, longitude, and altitude of each of the predetermined positions. Note that the information indicating each of the predetermined positions may be registered in advance in the sensing device 22, for example.

[0033] Next, the control unit 12 of the information processing device 10 estimates the area where the abnormality has occurred based on the data acquired by the acquisition unit 11 (step S2). Here, the information processing device 10 may first determine whether or not the transition of the vibration or sound measured by the optical fiber sensor 20 is abnormal, for example, by using AI (Artificial Intelligence) or the like.

[0034] If it is determined that there is an abnormality, the information processing device 10 may, for example, calculate the difference in time (arrival time difference) that it takes for the vibration or sound to propagate from the source of the vibration or sound to each predetermined position on the optical fiber cable 21. Then, based on each calculated arrival time difference, the information processing device 10 may calculate the difference in distance from each predetermined position to the source. Then, based on the calculated distance difference, the information processing device 10 may, for example, estimate a two-dimensional or three-dimensional area in which the source is located.

[0035] Next, the control unit 12 of the information processing device 10 refers to the equipment DB (Data Base) 501 and the type DB 601, and determines which equipment is to be inspected based on the measurement data acquired by the acquisition unit 11, among the equipment installed in the estimated area (step S3). This makes it possible to appropriately identify, for example, the equipment in which an abnormality has occurred.

[0036] In the example of FIG. 5, in the equipment DB 501, a type ID and information on an installation location are recorded (registered) in advance by an administrator (operator) or the like in association with the equipment ID. The equipment DB 501 may be recorded in a recording device inside the information processing device 10, or may be recorded in a DB server or the like outside the information processing device 10. The equipment ID is identification information of the equipment (device). The type ID is identification information of the type (model) of the equipment. The installation location is information indicating the location where the equipment is installed. The installation location may include information such as latitude, longitude, and altitude.

[0037] 6, one or more abnormality data are recorded (registered) in advance in the type DB 601 by an administrator (operator) or the like in association with a type ID. The type DB 601 may be recorded in a recording device inside the information processing device 10, or may be recorded in a DB server or the like outside the information processing device 10. The abnormality data may be, for example, waveform data indicating a transition of vibration or sound measured by the optical fiber sensor 20 or the like when an abnormality occurred in the past in equipment of a type related to the type ID.

[0038] The information processing device 10 may first extract each facility ID installed in an area where it is estimated that the source of the abnormal vibration or sound is located from the facility DB 501. Then, the information processing device 10 may extract each abnormality data associated with the type ID of each extracted facility ID from the type DB 601.

[0039] The information processing device 10 may then calculate the degree of similarity between the waveform of the measurement data measured by the optical fiber sensor 20 and the waveform of each of the extracted abnormal data. Here, the information processing device 10 may calculate the degree of similarity using the measurement data at a point having the largest maximum amplitude among the measurement data at each point measured by the optical fiber sensor 20. Furthermore, the information processing device 10 may calculate, for example, a correlation coefficient between the waveform of the measurement data and the waveform of the abnormal data as the degree of similarity.

[0040] Then, the information processing device 10 may determine each piece of equipment of the type for which the calculated similarity is equal to or greater than a threshold value as equipment to be inspected (checked). Also, the information processing device 10 may determine each piece of equipment of the type for which the calculated similarity is the highest as equipment to be inspected (checked).

[0041] Next, the output unit 13 of the information processing device 10 outputs information based on the equipment to be inspected determined by the control unit 12 (step S4). Here, the information processing device 10 may transmit, for example, a command to instruct the autonomously moving inspection device 30 to inspect the determined equipment to be inspected. In this case, the command may include, for example, information such as the installation location of the equipment to be inspected.

[0042] Then, the inspection device 30, which has an autonomous robot, unmanned aerial vehicle, or a balloon, may autonomously move to the location of the specified equipment to be inspected and transmit images of the surroundings of the equipment to be inspected taken by a camera to a monitoring center, etc.

[0043] <Modification> The information processing device 10 may be a device contained in one housing, but the information processing device 10 of the present disclosure is not limited to this. Each unit of the information processing device 10 may be realized by cloud computing configured by one or more computers, for example. At least a part of the processing of the information processing device 10 may be realized by, for example, an inspection device 30. The information processing device 10 may be built into, for example, the housing of the inspection device 30. Such information processing devices 10 are also included in examples of the "information processing device" of the present disclosure.
