[0002] In recent years, attention has been focused on technology that receives optical signals from an optical fiber network including optical fibers and analyzes various state information based on sensing data (e.g., vibration data, sound data, temperature data, etc.) superimposed on the optical signals.

[0003] The status information includes, for example, the behavior of people, vehicles, and animals, the status of structures such as utility poles, the status of railroad tracks and roads, and weather conditions. Moreover, optical fibers are laid on structures such as utility poles, roads, railroad tracks, the ocean floor, and the like.

[0004] However, some status information is preferably provided only to specific service providers. For example, status information related to the privacy of a company should be provided only to that company, and should not be leaked to other service providers. Therefore, there is a need to provide status information to a service provider in accordance with the service provider.

[0005] Related techniques include the technique described in Patent Document 1. In the technique described in Patent Document 1, a privacy protection mode and a normal mode are switched depending on the subject's location. For example, when the subject moves to a private space such as a toilet, the mode is switched to privacy protection mode, and measurement is interrupted or measurement data is not recorded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Note that the following description and drawings are omitted and simplified as appropriate for clarity of explanation. In addition, in each of the following drawings, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary.

[0015] <Embodiment 1> First, with reference to FIG. 1, a configuration example of an optical fiber sensing system according to the first embodiment will be described.

[0016] 1, the optical fiber sensing system according to the first embodiment includes an optical fiber network 10 and an optical fiber sensing device 20. The optical fiber sensing device 20 includes a communication unit 21, an identification unit 22, an analysis unit 23, and a providing unit 24.

[0017] The optical fiber network 10 is composed of one or more optical fibers 11. The optical fiber 11 may be an optical fiber dedicated to sensing, or an optical fiber used for both communication and sensing. The optical fiber 11 may be an existing optical fiber or a newly installed optical fiber.

[0018] The optical fiber 11 can be installed in the following locations, for example. - Electric poles, bridges, tunnels, pipes, dams, and other structures Railroads, roads ·Underground, undersea

[0019] The status information that can be analyzed by the optical fiber sensing system according to the first embodiment is, for example, a plurality of status information as follows. - Conditions including deterioration of structures such as utility poles, bridges, tunnels, pipes, and dams - Condition of railway tracks and roads, including deterioration - Track and road conditions - Behavior of people, vehicles, animals, etc. Volcanic eruptions, earthquakes, landslides, subsidence, cave-ins, rock falls, erosion, lake eruptions, wind and flood damage, wind damage, flood damage, salt damage, snow damage, snowstorms, freezing damage, lightning, high temperatures (heat waves, extreme heat, warm winters), low temperatures (severe winters, cold summers), natural fires and other natural disasters, and damage caused by natural disasters - Power outages, construction work, etc. Weather, temperature, ground temperature, wind speed, precipitation Communication failure

[0020] The communication unit 21 receives an optical signal from the optical fiber network 10. For example, the communication unit 21 transmits pulsed light to the optical fiber 11 constituting the optical fiber network 10, and receives backscattered light generated as the pulsed light is transmitted through the optical fiber 11 as an optical signal.

[0021] Here, when vibration, sound, temperature, etc. occur around the optical fiber 11, the vibration, sound, temperature, etc. are transmitted to the optical fiber 11, and the characteristics (e.g., wavelength) of the optical signal transmitted through the optical fiber 11 change. Therefore, the optical fiber 11 can detect sensing data including vibration data, sound data, temperature data, etc., and this sensing data is superimposed on the optical signal transmitted through the optical fiber 11.

[0022] The analysis unit 23 can use a plurality of analysis methods respectively associated with the plurality of state information described above. When analyzing certain state information, the analysis unit 23 uses the analysis method associated with the state information to analyze the state information based on the sensing data superimposed on the optical signal received by the communication unit 21.

[0023] Specifically, the sensing data superimposed on the optical signal is vibration data, sound data, temperature data, etc., as described above, but even the vibration data alone contains unique vibration patterns related to various state information. For example, if the optical fiber 11 is laid on a utility pole, the sensing data (vibration data) contains a unique vibration pattern corresponding to the deterioration state of the utility pole, a unique vibration pattern corresponding to the traffic conditions of vehicles traveling near the utility pole, a unique vibration pattern corresponding to weather conditions, etc. A unique pattern related to certain state information is a unique pattern that dynamically changes depending on the state indicated by that state information.

[0024] When analyzing certain status information, the analysis unit 23 analyzes the status information by using an analysis method related to the status information, as described above. This analysis method is, for example, a method of extracting a unique pattern related to the status information from the sensing data superimposed on the optical signal received by the communication unit 21, and analyzing the extracted unique pattern to analyze the status information.

[0025] However, some status information is preferably provided only to specific service providers. For example, status information related to the privacy of a company should be provided only to that company, and should not be leaked to other service providers.

[0026] Therefore, the identifying unit 22 identifies status information corresponding to the service provider from among the plurality of pieces of status information. At this time, the identifying unit 22 may identify status information of the monitoring exclusion target from among the plurality of pieces of status information, and identify the status information obtained by excluding the status information of the monitoring exclusion target from the plurality of pieces of status information as the status information corresponding to the service provider.

[0027] The status information of the monitoring exclusion target is, for example, status information related to confidential information of a nation or a local government, status information related to the privacy of an individual or a company, etc. The status information of the monitoring exclusion target may be defined for each service provider in accordance with the policy of the service provider, or status information of the monitoring exclusion target common to the service providers may be defined.

[0028] The analysis unit 23 uses an analysis method related to the status information identified by the identification unit 22 to extract a unique pattern related to the identified status information from the sensing data superimposed on the optical signal received by the communication unit 21, and analyzes the identified status information by analyzing the extracted unique pattern.

[0029] However, the sensing data includes all data such as vibrations occurring around the optical fiber 11. Therefore, some of the sensing data is not suitable for use in analyzing the state information.

[0030] Therefore, the analysis unit 23 may exclude sensing data that is to be excluded from monitoring from the sensing data superimposed on the optical signal received by the communication unit 21, and use the remaining sensing data to analyze the status information identified by the identification unit 22.

[0031] The sensing data to be excluded from monitoring is sensing data detected in national and local government facilities, sensing data related to personal information of individuals and companies, etc. Note that the sensing data to be excluded from monitoring may be sensing data detected in a specific position or area, sensing data detected in a specific time period, or sensing data of a specific frequency.

[0032] At this time, the analysis unit 23 can identify the position on the optical fiber 11 (the distance from the communication unit 21) where the sensing data superimposed on the optical signal was detected based on the time difference between the time when the communication unit 21 sent out the pulsed light to the optical fiber 11 and the time when the communication unit 21 received the optical signal from the optical fiber 11. Furthermore, the analysis unit 23 may previously hold an area DB (DataBase) that associates the position on the optical fiber 11 (the distance from the communication unit 21) with the identifier of each area on the map, as shown in Fig. 2. This allows the analysis unit 23 to determine in which area on the map the sensing data was detected, i.e., which area's status information is being analyzed.

[0033] The providing unit 24 provides the state information identified by the identifying unit 22 and analyzed by the analyzing unit 23 to the service destination.

[0034] Next, an example of the flow of operations of the optical fiber sensing system according to the first embodiment will be described with reference to FIG. As shown in FIG. 3, first, the optical fiber network 10 (optical fiber 11) detects sensing data (step S11). Next, the communication unit 21 receives the optical signal on which the sensing data is superimposed from the optical fiber network 10 (optical fiber 11) (step S12).

[0035] Next, the identifying unit 22 identifies status information corresponding to the service destination from among a plurality of pieces of status information that can be analyzed by the optical fiber sensing system according to the first embodiment (step S13). This identification may be performed by the method of identifying status information of a monitoring exclusion target, as described above.

[0036] Next, the analysis unit 23 uses an analysis method related to the state information identified by the identification unit 22 from among the multiple analysis methods to analyze the identified state information based on the sensing data superimposed on the optical signal received by the communication unit 21 (step S14). As described above, this analysis may be performed by a method of extracting a unique pattern related to the identified state information from the sensing data and analyzing the extracted unique pattern. Thereafter, the providing unit 24 provides the service destination with the state information identified by the identifying unit 22 and analyzed by the analyzing unit 23 (step S15).

[0037] As described above, according to the first embodiment, the identifying unit 22 identifies status information corresponding to a service destination from among a plurality of pieces of status information. The analyzing unit 23 analyzes the identified status information based on the sensing data superimposed on the received optical signal, using an analysis method related to the identified status information from among a plurality of analysis methods. This makes it possible to provide the service destination with status information corresponding to the service destination.

[0038] According to the first embodiment, the identifying unit 22 may identify the status information of the monitoring exclusion target from among a plurality of status information, and identify the status information corresponding to the service provider based on the status information of the monitoring exclusion target. This makes it possible to prevent the status information of the monitoring exclusion target, which is status information related to the privacy of a company, from being leaked to the service provider that is another company.

[0039] According to the first embodiment, the analysis unit 23 may exclude sensing data of monitoring exclusion targets from the sensing data, and analyze the specified state information based on the remaining sensing data. This makes it possible to prevent sensing data of monitoring exclusion targets, such as sensing data detected in a national facility, from being used in the analysis of the state information.

[0040] <Embodiment 2> Next, with reference to FIG. 4, a configuration example of an optical fiber sensing system according to the second embodiment will be described. As shown in FIG. 4, the optical fiber sensing system according to the second embodiment is a more specific example of the optical fiber sensing system according to the first embodiment described above.

[0041] Specifically, in the optical fiber sensing system according to the second embodiment, an optical fiber network 10 is formed by an optical fiber 11 laid on a utility pole P, and three service destinations X, Y, and Z exist.

[0042] Moreover, it is assumed that the state information that can be analyzed by the optical fiber sensing system according to the second embodiment is the following three items. Condition information A: Deterioration state of utility pole P Status information B: Traffic conditions of vehicles traveling near utility pole P Condition information C: Weather conditions

[0043] Here, as an example, an analysis method for analyzing the state information A indicating the deterioration state of the utility pole P will be described. First, the analysis unit 23 extracts a vibration pattern as shown in Fig. 5 and Fig. 6 from the sensing data superimposed on the optical signal received by the communication unit 21. Fig. 5 and Fig. 6 show a vibration pattern after FFT (Fast Fourier Transform) of a vibration pattern in which the horizontal axis indicates time and the vertical axis indicates vibration intensity. In the vibration patterns shown in Fig. 5 and Fig. 6, the horizontal axis indicates frequency and the vertical axis indicates vibration intensity.

[0044] In the vibration patterns shown in Figures 5 and 6, a peak in vibration intensity occurs. The magnitude of the peak in vibration intensity and the frequency at which this peak occurs vary depending on the deterioration state of the utility pole P. Specifically, when the utility pole P is in a deteriorated state (Figure 6), the magnitude of the peak in vibration intensity is larger and the frequency at which this peak occurs is shifted to the higher frequency side compared to when the utility pole P is in a normal state (Figure 5).

[0045] Therefore, the analysis unit 23 judges the deterioration state of the utility pole P based on the magnitude of the vibration intensity peak and the frequency at which this peak occurs. Note that the analysis unit 23 may previously hold a utility pole DB that associates the position on the optical fiber 11 (the distance from the communication unit 21) with the identifier of each utility pole P, as shown in Fig. 7. This allows the analysis unit 23 to judge which utility pole P the sensing data was detected on, i.e., which utility pole P's deterioration state is being analyzed.

[0046] In the optical fiber sensing system according to the second embodiment, status information of the monitoring excluded targets is defined for each service destination X, Y, Z, and the identification unit 22 is assumed to hold in advance a monitoring excluded target DB in which identifiers of the service destinations X, Y, Z are associated with status information of the monitoring excluded targets of each service destination X, Y, Z, as shown in FIG. 8.

[0047] Furthermore, in the optical fiber sensing system of this embodiment 2, the sensing data to be excluded from monitoring is defined as sensing data detected in area R1 (see Figure 2), and the analysis unit 23 is assumed to previously store information (not shown) on the sensing data to be excluded from monitoring.

[0048] The flow of operations of the optical fiber sensing system according to the second embodiment is similar to that of the first embodiment shown in Fig. 3. Specifically, the flow is as follows.

[0049] Step S11: First, the optical fiber network 10 (optical fiber 11) detects sensing data.

[0050] Step S12: Next, the communication unit 21 receives the optical signal on which the sensing data is superimposed from the optical fiber network 10 (optical fiber 11).

[0051] Step S13: Next, the identifying unit 22 refers to the monitoring excluded target DB of FIG. 8 and identifies status information corresponding to each of the service destinations X, Y, and Z in no particular order.

[0052] 8, for example, the monitoring exclusion targets for service destination X are status information B and C. Therefore, the identifying unit 22 identifies status information A, which is obtained by excluding status information B and C from status information A and BC that can be analyzed by the optical fiber sensing system according to the second embodiment, as status information corresponding to service destination X. Similarly, the identifying unit 22 identifies status information B and C corresponding to service destination Y, and identifies status information A and C corresponding to service destination Z.

[0053] Step S14: Next, the analysis unit 23 analyzes, in no particular order, each of the status information A, B, and C. For example, the status information A indicating the deterioration state of the utility pole P is analyzed as follows.

[0054] First, the analysis unit 23 acquires sensing data superimposed on the optical signal received by the communication unit 21. However, in the present embodiment 2, sensing data detected in the area R1 (see FIG. 2) is defined as sensing data to be excluded from monitoring.

[0055] Therefore, next, the analysis unit 23 removes the sensing data detected in the region R1 from the sensing data acquired above. Hereinafter, the sensing data after this removal is referred to as the remaining sensing data.

[0056] Next, the analysis unit 23 analyzes the status information A using an analysis method related to the status information A. Specifically, the analysis unit 23 extracts vibration patterns as shown in Fig. 5 and Fig. 6 from the remaining sensing data, and analyzes the deterioration state of the utility pole P based on the magnitude of the vibration intensity peak in the extracted vibration pattern and the frequency at which this peak occurs. At this time, the analysis unit 23 can determine which utility pole P's deterioration state is being analyzed by referring to the utility pole DB shown in Fig. 7. This completes the analysis of the state information A. The analysis unit 23 also analyzes the other state information B and C using the analysis method related to the state information B and C.

[0057] Step S15: Thereafter, the providing unit 24 provides the status information A to the service providing destination X, the status information B and C to the service providing destination Y, and the status information A and C to the service providing destination Z, in random order.

[0058] The optical fiber sensing system according to the second embodiment is a more specific example of the optical fiber sensing system according to the above-mentioned first embodiment. Therefore, according to the second embodiment, the same effects as those of the above-mentioned first embodiment can be obtained. The specific effects obtained by the second embodiment are as follows.

[0059] Status information according to service providers X, Y, and Z can be provided to those service providers X, Y, and Z, respectively. It is possible to prevent the leakage of status information B and C, which are excluded from monitoring for service provider X, to service provider X. Similarly, it is possible to prevent the leakage of status information A to service provider Y, and the leakage of status information B to service provider Z. It is possible to prevent sensing data detected in area R1 (see Figure 2) that is subject to monitoring exclusion from being used in analysis.

[0060] <Other embodiments> In the above-described first and second embodiments, the communication unit 21 is provided inside the optical fiber sensing device 20, but this is not limiting. The communication unit 21 may be separated from the optical fiber sensing device 20. Fig. 9 shows a configuration example of an optical fiber sensing system in which the communication unit 21 is separated from the optical fiber sensing device 20. In the optical fiber sensing system shown in Fig. 9, the optical fiber sensing device 20 can be installed at a location away from the communication unit 21, and can be arranged on the cloud, for example.

[0061] <Hardware configuration of optical fiber sensing device> Next, with reference to FIG. 10, a hardware configuration of the computer 30 that realizes the optical fiber sensing device 20 according to the above-mentioned first and second embodiments will be described.

[0062] 10, the computer 30 includes a processor 301, a memory 302, a storage 303, an input / output interface (input / output I / F) 304, and a communication interface (communication I / F) 305. The processor 301, the memory 302, the storage 303, the input / output interface 304, and the communication interface 305 are connected by a data transmission path for transmitting and receiving data to and from each other.

The memory 302 is, for example, a random access memory (RAM) or a read only memory (ROM). The storage 303 is, for example, a storage device such as a hard disk drive (HDD), a solid state drive (SSD), or a memory card. The storage 303 may also be a memory such as a RAM or a ROM.

[0064] The storage 303 stores programs that realize the functions of the components of the optical fiber sensing device 20. The processor 301 executes each of these programs to realize the functions of the components of the optical fiber sensing device 20. When executing each of the above programs, the processor 301 may read these programs onto the memory 302 and then execute them, or may execute them without reading them onto the memory 302. The memory 302 and the storage 303 also serve to store information and data held by the components of the optical fiber sensing device 20.

[0065] The above-mentioned program can be stored using various types of non-transitory computer readable media and can be supplied to a computer (including the computer 30). The non-transitory computer readable medium includes various types of tangible storage media. Examples of the non-transitory computer readable medium include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), compact disc-ROMs (CD-ROMs), CD-recordables (CD-Rs), CD-rewritables (CD-R / Ws), semiconductor memories (e.g., mask ROMs, programmable ROMs (PROMs), erasable PROMs (EPROMs), flash ROMs, and RAMs). The program can also be supplied to a computer by various types of transitory computer readable media. Examples of the transitory computer readable medium include electric signals, optical signals, and electromagnetic waves. The transitory computer readable medium can supply the program to a computer via a wired communication path such as an electric wire and an optical fiber, or via a wireless communication path.

[0066] The input / output interface 304 is connected to a display device 3041, an input device 3042, a sound output device 3043, and the like. The display device 3041 is a device that displays a screen corresponding to drawing data processed by the processor 301, such as an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube) display, or a monitor. The input device 3042 is a device that accepts an operation input by an operator, and is, for example, a keyboard, a mouse, or a touch sensor. The display device 3041 and the input device 3042 may be integrated and realized as a touch panel. The sound output device 3043 is a device that acoustically outputs a sound corresponding to the sound data processed by the processor 301, such as a speaker.

[0067] The communication interface 305 transmits and receives data to and from an external device. For example, the communication interface 305 communicates with the external device via a wired communication path or a wireless communication path.

Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
