Description

[Technical Field]

[0001] The present invention relates to a waterway facilities management support system, a waterway facilities management support method, and a program. [Background technology]

[0002] A system has been disclosed in which a worker evaluates whether or not the inspection of the equipment to be inspected has been carried out correctly (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2022-54521 Summary of the Invention [Problem to be solved by the invention]

[0004] The patrol inspection work evaluation system described in Patent Document 1 acquires, from a position detection terminal, position detection information that associates the position of a worker with the time at which the worker's position was detected. The patrol inspection work evaluation system also acquires the inspection result input time at which the worker inputs the inspection result into the operation terminal. The patrol inspection work evaluation system then identifies the inspection work position based on the time of the position detection information and the inspection result input time. The patrol inspection work evaluation system calculates a value (e.g., distance) related to the positional relationship between the inspection work position and the position of the equipment to be inspected, and evaluates that the inspection was performed correctly if the value is within a predetermined range. This allows the patrol inspection work evaluation system to evaluate whether the worker performed the inspection correctly without requiring a dedicated device to transmit a signal indicating the completion of the inspection work.

[0005] However, the patrol inspection work evaluation system described in Patent Document 1 cannot identify areas that require priority inspection during normal inspections and emergency inspections such as in the event of a disaster, which creates the problem of not being able to carry out appropriate inspections of facilities.

[0006] In view of the above problems, the present invention aims to realize appropriate inspection of waterway facilities. [Means for solving the problem]

[0007] A waterway facility management support system according to one embodiment of the present invention comprises a location information acquisition unit that acquires terminal location information indicating the location of a terminal device of a worker inspecting waterway facilities of a specified waterway system; a defective facility identification unit that, when information indicating that operation input by the worker to the terminal device has been received is acquired from the terminal device, identifies a first defective facility, which is at least one of the defective facilities that is in a specified positional relationship with the location of the terminal device, based on the terminal location information and defective facility location information indicating the location of a defective facility, which is a waterway facility that has previously experienced an abnormality; and a notification unit that notifies the terminal device of first defective facility information regarding the first defective facility.

[0008] A waterway facility management support method according to one embodiment of the present invention involves a computer acquiring terminal location information indicating the location of a terminal device of a worker inspecting waterway facilities of a specified waterway system, and when the computer acquires information from the terminal device indicating that operation input by the worker to the terminal device has been received, identifying a first defective facility, which is at least one of the defective facilities that is in a specified positional relationship with the location of the terminal device, based on the terminal location information and defective facility location information indicating the location of a defective facility, which is a waterway facility that has previously experienced an abnormality, and notifying the terminal device of first defective facility information regarding the first defective facility.

[0009] A program according to one embodiment of the present invention causes a computer to acquire terminal location information indicating the location of a terminal device of a worker inspecting waterway facilities of a specified waterway system, and when information indicating that operation input by the worker to the terminal device has been received is acquired from the terminal device, identify a first defective facility, which is at least one of the defective facilities that is in a specified positional relationship with the location of the terminal device, based on the terminal location information and defective facility location information indicating the location of a defective facility, which is a waterway facility that has previously experienced an abnormality, and notify the terminal device of first defective facility information regarding the first defective facility.

[0012] Below, a waterway facilities management support system 10 according to one embodiment of the present invention will be described in detail with reference to the drawings. However, the embodiment described below is merely an example, and is not intended to exclude various modifications or the application of technologies not explicitly stated below. In other words, the present invention can be implemented by various modifications or combinations of the embodiments within the scope of its purpose. Furthermore, in the following description of the drawings, identical or similar parts are denoted by the same or similar reference numerals.

[0013] === Overview of Waterway Facilities Management Support System 10 === <<Configuration Overview>> An overview of the configuration of the waterway facilities management support system 10 will be described with reference to Figure 1. Figure 1 is a diagram showing an overview of the functional parts and processing of the waterway facilities management support system 10. The waterway facilities management support system 10 is a system for managing waterway facilities in a specified waterway system.

[0014] The predetermined waterway system is a system of waterways through which water taken from a predetermined water intake flows.

[0015] A waterway facility is a facility that constitutes a specific waterway system, and includes, for example, an artificially constructed structure for flowing water and the control equipment that controls it. Specifically, a waterway facility includes, for example, a headrace through which water flows, a gate installed in the headrace, a hoist that operates the gate, a control equipment that controls the operation of the hoist, and a building that houses the hoist and the control equipment.

[0016] As shown in FIG. 1, the waterway facilities management support system 10 includes, for example, a waterway management device 100 and a terminal device 200.

[0017] The waterway management device 100 is a device that automatically notifies workers of waterway facilities (hereinafter referred to as "faulty facilities") that have previously experienced abnormalities and are located in a predetermined positional relationship with the waterway facilities that are the subject of inspection by workers.

[0018] The predetermined positional relationship is a positional relationship that is determined in advance in relation to the worker's terminal device 200. Specifically, the predetermined positional relationship may be, for example, a positional relationship that is included in a predetermined range (for example, a radius of 1000 m) centered on the position of the terminal device 200, or a positional relationship that is included in a predetermined section of a water conduit that the terminal device 200 is close to. In other words, the predetermined positional relationship is a positional relationship between the worker and the object that allows the worker to move efficiently from the worker's current location.

[0019] The defective facility may be, for example, a water conduit that is experiencing an abnormality such as cracking, spalling, flaking, erosion, or springing, or it may be control equipment that has experienced an abnormality in the past, or it may be a building that has experienced an abnormality (cracks, spalling, etc.).

[0020] The terminal device 200 is a terminal device operated by an operator, and is a device that can acquire information about defective facilities from the waterway management device 100 by linking with the waterway management device 100.

[0021] The waterway management device 100 may be, for example and without limitation, a cloud computer, a server computer, a personal computer (e.g., desktop, laptop, tablet, etc.), a media computing platform (e.g., cable or satellite set-top box, digital video recorder), a handheld computing device (e.g., PDA, email client, etc.), or any other type of computer or communication platform. Note that at least a portion of the processing in the waterway management device 100 may or may not be implemented by one or more computers (for example and without limitation, cloud computing configured by one or more computers).

[0022] The terminal device 200 may be, for example and without limitation, a smartphone, a mobile phone (feature phone), a personal computer (e.g., desktop, laptop, tablet, etc.), a media computing platform (e.g., cable, satellite set-top box, digital video recorder), a handheld computing device (e.g., PDA (Personal Digital Assistant), email client, etc.), a wearable device (e.g., eyeglasses, watch, etc.), or another type of computer or communication platform.

[0023] <<Processing Overview>> Next, an overview of the processing of the waterway facilities management support system 10 will be described with reference to FIG.

[0024] In step S10, the terminal device 200, for example, receives operational input from a worker and transmits information relating to the inspection results of the waterway facilities (hereinafter referred to as "inspection result information") to the waterway management device 100. The terminal device 200 transmits location information indicating the location of the terminal device 200 (hereinafter referred to as "terminal location information") to the waterway management device 100. The terminal device 200 may automatically transmit the location information to the waterway management device 100 periodically, for example, using a beacon or GPS.

[0025] The inspection result information may be, for example, information indicating that input of the inspection result has been completed, or information indicating the content of the inspection result.

[0026] In step S11, the waterway management device 100 acquires, for example, inspection result information and terminal position information. The waterway management device 100 stores the inspection result information and terminal position information in the storage unit 110.

[0027] In step S12, the waterway management device 100 refers to the memory unit 110 and, based on the terminal location information, identifies at least one faulty facility (hereinafter referred to as the "first faulty facility") that has previously experienced an abnormality and is located in a predetermined positional relationship with the location of the terminal device 200.

[0028] In step S13, the waterway management device 100 determines whether the degree of abnormality of the first malfunctioning facility satisfies a predetermined condition.

[0029] The degree of abnormality is a parameter that indicates the degree of abnormality of a defective facility. The degree of abnormality may, for example, be a numerical indication of the degree of abnormality, or may be an indication of the degree of abnormality in multiple stages. For example, when the degree of abnormality is indicated in multiple stages, it may be evaluated as S-1 to S-5, in which case S-5 indicates a state in which there is no abnormality in the waterway facility, S-1 indicates an abnormal state that has a significant impact on the stability of the waterway facility, and the degree of abnormality that has a greater impact on the stability of the waterway facility increases from S-5 to S-1.

[0030] The specified condition refers to the result of comparing the degree of abnormality with a standard; for example, if the degree of abnormality is expressed numerically, it may be the result of comparing with a threshold value, or if the degree of abnormality is expressed in multiple stages, it may be the result of identifying whether or not it is at a predetermined stage.

[0031] In step S14, if the degree of abnormality of the first defective facility (each of at least one defective facility) satisfies a predetermined condition, the waterway management device 100 notifies the terminal device 200 of information regarding the defective facility that satisfies the predetermined condition (hereinafter referred to as ``first defective facility information'').

[0032] The first defective facility information includes, for example, information such as the specifications of the first defective facility and past inspection results.

[0033] In this way, when workers are performing normal or emergency inspections, the waterway management device 100 notifies the worker's terminal device 200 of past repair status, abnormality history, specifications, etc., regarding abnormalities in faulty facilities that require continuous monitoring, allowing the worker to check for any faulty facilities without missing any. This enables the waterway facilities management support system 10 to achieve more efficient preventive maintenance and stock management of waterway facilities.

[0034] ==Waterway management device 100== The functional configuration of the waterway management device 100 will be described with reference to Fig. 1. As shown in Fig. 1, the waterway management device 100 may include functional units such as a storage unit 110, an acquisition unit 120, a defective facility identification unit 130, an abnormality degree identification unit 140, an abnormality degree determination unit 150, a similar facility identification unit 160, and a notification unit 170. The functional units are functions that are realized, for example, by a processor 1001 reading out a program stored in a memory 1002.

[0035] The storage unit 110 stores, for example, an inspection result database D111 and a waterway facilities database D112.

[0036] An example of the inspection result database D111 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the inspection result database D111. The inspection result database D111 is a database that stores current and past inspection results, and is a database that is referenced when executing processing by various functional units.

[0037] As shown in FIG. 2, the inspection result database D111 may include items such as [Facility ID], [Facility Name], [Location], [Inspection Results], [Level of Abnormality], and [Progression of Abnormality]. [Facility ID] stores a facility ID, which is identification information that can uniquely identify a waterway facility (such as a waterway, building, gate, or control equipment). [Location] stores coordinates indicating the latitude and longitude of the waterway facility, as well as a facility number. [Inspection Results] stores information indicating the contents of past inspection results for the waterway facility. [Level of Abnormality] stores information indicating the level of abnormality of the waterway facility. [Progression of Abnormality] stores information indicating the progression of the level of abnormality; for example, if the level of abnormality is worsening, information indicating that this is worsening is stored.

[0038] An example of the waterway facility database D112 will be described with reference to Figure 3. Figure 3 is a diagram showing an example of the configuration of the waterway facility database D112. The waterway facility database D112 manages various information related to waterway facilities. By referring to the waterway facility database D112, the waterway management device 100 can, for example, transmit the specifications of a waterway facility to the terminal device 200, and can also identify waterway facilities with specifications similar to those of a defective facility.

[0039] As shown in Figure 3, the waterway facility database D112 may include items such as [Facility ID], [Facility Name], [Location], [Specifications], [Similar Facilities], and [Importance]. [Facility ID] stores the facility ID, which is identification information that can uniquely identify a waterway facility. [Location] stores the coordinates and facility number of the waterway facility. [Specifications] stores information indicating the specifications (such as specifications) of the waterway facility. [Similar Facilities] stores identification information (such as facility ID) that can identify waterway facilities with specifications similar to the waterway facility in question. [Importance] stores the importance of the waterway facility in question (in Figure 3, as an example, the highest importance is set to "1"). Importance will be described later. The items [Similar Facilities] and [Importance] may be associated with the [Facility ID] item of the inspection result database D111 in Figure 2 and reflected in the inspection result database D111.

[0040] The acquisition unit 120 acquires various types of information from other devices. For example, the acquisition unit 120 acquires inspection result information and terminal location information from the worker's terminal device 200. Furthermore, for example, the acquisition unit 120 may acquire information indicating that the worker has performed an operation input to the terminal device 200 (hereinafter referred to as "operation information").

[0041] The operation information may be, for example, information regarding the input of inspection results, information regarding the operation of photographing, or information indicating that an operation input has been received for a specified object (such as a button to identify defective facilities) displayed on the display unit of the terminal device 200.

[0042] The defective facility identifying unit 130 identifies a defective facility that has a predetermined positional relationship with the terminal device 200 as a first defective facility. Specifically, when the defective facility identifying unit 130 acquires operation information from the terminal device 200, it identifies the position of the terminal device 200. Here, the defective facility identifying unit 130 refers to the inspection result database D111 and identifies a defective facility that has a predetermined positional relationship with the position of the terminal device 200 (for example, within a radius of 1000 m) based on position information of the defective facility (hereinafter referred to as "defective facility position information") as the first defective facility.

[0043] The first defective facility may include multiple defective facilities. That is, for example, when multiple defective facilities are identified to be in a predetermined positional relationship with the terminal device 200, the defective facility identifying unit 130 may identify the multiple defective facilities as the first defective facilities. Specifically, for example, when the terminal device 200 is located in a predetermined building of the waterway facility, the defective facility identifying unit 130 may identify the building as a defective facility exhibiting an abnormality such as peeling, and a water conduit near the building as a defective facility exhibiting an abnormality such as peeling, as the first defective facility.

[0044] The abnormality degree identifying unit 140 identifies the abnormality degree of the first malfunction facility. Specifically, the abnormality degree identifying unit 140 refers to the inspection result database D111 to identify the abnormality degree of at least one malfunction facility that is the first malfunction facility.

[0045] The abnormality degree determination unit 150 determines whether the abnormality degree of each of at least one malfunctioning facility that is the first malfunctioning facility satisfies a predetermined condition. Specifically, the abnormality degree determination unit 150 may determine that the predetermined condition is satisfied when the abnormality degree indicated by a numerical value exceeds a predetermined threshold. Furthermore, the abnormality degree determination unit 150 may determine that the predetermined condition is satisfied when the abnormality degree indicated by multiple levels corresponds to a predetermined level (for example, S-3, S-2, S-1, which indicate greater impact on the facility).

[0046] The similar facility identification unit 160 identifies a defective facility (hereinafter referred to as a "second defective facility") that is a waterway facility (hereinafter also referred to as a "similar facility") that has specifications similar to the specifications of at least one of the first defective facilities.

[0047] The second defective facility may include multiple defective facilities. That is, for example, when multiple defective facilities are identified as having specifications similar to at least one of the first defective facilities, the similar facility identification unit 160 may identify the identified multiple defective facilities as the second defective facilities.

[0048] Specifically, for example, when the first defective facility is a predetermined culvert portion of a waterway, the similar facility identification unit 160 refers to the waterway facility database D112 and identifies identification information (e.g., facility name or facility ID) of at least one culvert portion having specifications similar to those of the predetermined culvert portion that is the first defective facility. Then, when the similar facility identification unit 160 refers to the inspection result database D111 based on the identification information and identifies the culvert portion as a defective facility, it may identify the culvert portion as a second defective facility.

[0049] In addition, if the inspection result database D111 pre-stores an item (for example, the [Similar Facilities] item in the waterway facility database D112) that can identify a waterway facility similar to each waterway facility of each facility ID (each first defective facility), the similar facility identification unit 160 may identify the second defective facility by referring to that item in the inspection result database D111.

[0050] In addition, if the inspection result database D111 and the waterway facility database D112 do not contain an item corresponding to the [Similar Facilities] item in the waterway facility database D112, the similar facility identification unit 160 may identify similar facilities with similar specifications by performing text analysis using machine learning on the specifications of each waterway facility included in the waterway facility database D112.

[0051] The similar facility identification unit 160 may identify a second malfunctioning facility based on a change over time in the degree of abnormality of a first malfunctioning facility. Specifically, the similar facility identification unit 160 identifies whether the degree of abnormality at a first time point in the past (hereinafter referred to as the "first degree of abnormality") for each of at least one malfunctioning facility that is the first malfunctioning facility is worse than the degree of abnormality at a second time point that is earlier than the first time point (hereinafter referred to as the "second degree of abnormality") for each of at least one malfunctioning facility that is the first malfunctioning facility. The similar facility identification unit 160 identifies a second malfunctioning facility related to the malfunctioning facility identified as having a worsening degree of abnormality.

[0052] Specifically, the similar facility identification unit 160 refers to the inspection result database D111 and, based on the inspection result information, identifies a second defective facility related to a defective facility that has been identified as having a worsening degree of abnormality if the numerical value indicating the degree of abnormality has increased (for example, if it has increased from 20 to 30) or if the stage indicating the degree of abnormality has worsened (for example, if it has worsened from S-3 to S-1).

[0053] The notification unit 170 notifies the terminal device 200 of various information related to the defective facility.

[0054] Specifically, the notification unit 170 may, for example, transmit to the terminal device 200 first defective facility information regarding a first defective facility identified as being in a predetermined positional relationship with the terminal device 200. This enables the waterway facilities management support system 10 to ensure that workers properly inspect the defective facility, for example, during inspections. Furthermore, the waterway facilities management support system 10 can provide information indicating the specifications of the defective facility and changes in abnormal conditions to the workers during inspections, thereby enabling them to carry out appropriate inspection work.

[0055] Furthermore, specifically, for example, for each of at least one first malfunctioning facility identified as being in a predetermined positional relationship with the terminal device 200, the notification unit 170 may notify the terminal device 200 of first malfunctioning facility information relating to the malfunctioning facility, which is determined by the abnormality degree determination unit 150 to satisfy a predetermined condition among the at least one first malfunctioning facility. This enables the waterway facilities management support system 10 to provide information about waterway facilities with particularly noticeable abnormalities to the workers, for example, during their inspection, thereby enabling them to carry out efficient inspection work.

[0056] Specifically, the notification unit 170 may notify the terminal device 200 of, for example, information regarding the second defective facility identified by the similar facility identification unit 160 (hereinafter referred to as "second defective facility information"). The second defective facility information includes, for example, information such as the specifications and past inspection results of each of at least one defective facility that is the second defective facility. The notification unit 170 may or may not transmit the second defective facility information together with the first defective facility information. This allows the waterway facilities management support system 10 to have workers check past abnormalities in waterway facilities similar to the waterway facility being inspected, thereby enabling preventive maintenance such as increasing the frequency of inspections of similar waterway facilities.

[0057] Furthermore, specifically, the notification unit 170 may notify the terminal device 200 of second malfunctioning facility information relating to a second malfunctioning facility that is similar to a malfunctioning facility that has been identified by the similar facility identification unit 160 as having a worsening degree of abnormality among at least one of the first malfunctioning facilities. As a result, when the abnormal condition of the first malfunctioning facility is worsening, the waterway facilities management support system 10 can determine that similar facilities similar to the first malfunctioning facility are also likely to have a worsening abnormal condition, automatically extract the similar facilities, and notify workers of information relating to the similar facilities, thereby enabling preventive maintenance such as increasing the frequency of inspections of similar waterway facilities.

[0058] The notification unit 170 may generate a screen for displaying various information on the display unit of the terminal device 200. Specifically, the notification unit 170 may generate information for displaying a defective facility notification screen T10 on the display unit of the terminal device 200.

[0059] The malfunctioning facility notification screen T10 will be described with reference to Fig. 4. Fig. 4 is a screen showing an example of the malfunctioning facility notification screen T10. The malfunctioning facility notification screen T10 is a screen for notifying a worker of first malfunctioning facility information and second malfunctioning facility information.

[0060] As shown in FIG. 4, the malfunctioning facility notification screen T10 includes a waterway system display area T11, a first malfunctioning facility display area T12, and a second malfunctioning facility display area T13.

[0061] The waterway system display area T11 is an area that displays, for example, an outline of a waterway facility in a plan view. In the waterway system display area T11, for example, the current position of the terminal device 200 is displayed as position T11a, and the first defective facility identified by the defective facility identification unit 130 is displayed as first defective facility T11b. This allows the waterway facilities management support system 10 to allow workers to easily understand the positional relationship between the current position and the first defective facility T11b.

[0062] Furthermore, in the waterway system display area T11, for example, the second defective facility identified by the similar facility identification unit 160 is displayed as second defective facilities T11c, T11d. This allows the waterway facilities management support system 10 to allow the worker to easily understand the positional relationship between the current location and the second defective facilities T11c, T11d.

[0063] Furthermore, the waterway system display area T11 may display the travel route from the current location to the first defective facility T11b and the second defective facilities T11c and T11d, respectively. This allows the waterway facilities management support system 10 to easily move workers to the waterway facilities to be inspected.

[0064] The first defective facility display area T12 displays information such as the degree of abnormality, past inspection results, specifications, etc. of at least one defective facility that is the first defective facility, based on the first defective facility identified by the defective facility identification unit 130, by referencing the inspection result database D111 and the waterway facility database D112. This allows the waterway facility management support system 10 to have the worker inspect the nearby first defective facility during the worker's waterway facility inspection work, thereby enabling preventive maintenance to be carried out.

[0065] The second defective facility display area T13 displays information such as the degree of abnormality, past inspection results, and specifications of the second defective facility in a manner that can be confirmed by workers, by referencing the inspection result database D111 and the waterway facility database D112, based on the second defective facility identified by the similar facility identification unit 160. This enables the waterway facility management support system 10 to increase the frequency with which workers inspect second defective facilities that are similar to the first defective facility during their waterway facility inspection work, thereby enabling preventive maintenance to be carried out.

[0066] The first malfunctioning facility display area T12 or the second malfunctioning facility display area T13 may include information indicating that the abnormal condition of the first malfunctioning facility is worsening. This allows the waterway facilities management support system 10 to enable workers to identify malfunctioning facilities whose abnormal conditions are worsening and similar facilities whose abnormal conditions may be worsening, thereby enabling preventive maintenance to be carried out.

[0067] === Variations === A modified waterway facilities management support system 10a will be described with reference to Figures 5 and 6. Figure 5 is a diagram showing an overview of the configuration of the modified waterway facilities management support system 10a. Figure 6 is a screen showing an example of a list notification screen T20. Below, only the differences from the waterway facilities management support system 10 will be described, and unless otherwise specified, it will be assumed that the waterway facilities management support system 10 is the same as the waterway facilities management support system 10.

[0068] <<First Modification>> In comparison with the waterway facilities management support system 10, the waterway facilities management support system 10a may further include a list generation unit 180 in the waterway management device 100a.

[0069] The list generation unit 180 creates a list of priorities for inspection work on the waterway facilities to be inspected. Specifically, the list generation unit 180 may, for example, refer to the waterway facilities database D112 to generate a list (hereinafter referred to as a "first list") that is prioritized based on the importance of the waterway facilities.

[0070] The importance level is an indicator of importance in water management. For example, a high importance level is assigned to a waterway that serves as the main line of a waterway system, while a low importance level is assigned to a waterway facility that has little impact on water supply, such as a waterway at the end of a waterway facility. For example, a high importance level may be assigned to a waterway facility located above train tracks or roads, under a river, adjacent to important facilities such as hospitals, or adjacent to private homes, while a low importance level may be assigned to a waterway facility that is unlikely to be affected or damaged by leaks or other causes. Furthermore, the importance level may be set higher for a section through which water for multiple uses, including municipal water, industrial water, and agricultural water, than for a section through which only agricultural water flows. The importance level is stored, for example, in association with the [facility ID] item in the inspection result database D111 and the waterway facility database D112.

[0071] For example, the list generating unit 180 generates a first list in which the priority of waterway facilities with a relatively high level of importance is set high and the priority of waterway facilities with a relatively low level of importance is set low.

[0072] At the time of an earthquake, the list generation unit 180 generates a list (hereinafter referred to as the "second list") different from the first list, in which each waterway facility in a specified waterway system is prioritized based on specified conditions.

[0073] The predetermined conditions include, for example, conditions regarding the seismic intensity when an earthquake occurs, conditions regarding hazard maps, and conditions regarding the rate of water leakage accidents in waterway facilities.

[0074] Specifically, when the acquisition unit 120 acquires information indicating the current seismic intensity for each location (hereinafter referred to as "earthquake information") at the time of an earthquake, the list generation unit 180 generates a second list by prioritizing each of the multiple waterway facilities based on the importance corresponding to each of the multiple waterway facilities and the seismic intensity indicated by the earthquake information. The earthquake information may include, for example, the current speed, acceleration, and SI (Spectral Intensity) value for each location. In the following description, it is assumed that the earthquake information is information indicating the seismic intensity.

[0075] In this case, the list generation unit 180 may generate the second list by prioritizing each of the multiple waterway facilities based on the total value (hereinafter referred to as the "changed value") obtained by multiplying the importance and seismic intensity (for example, normalized values) of each of the multiple waterway facilities by a weighting. That is, the second list is set, for example, taking into account the importance of each waterway facility, so that waterway facilities located in areas with relatively high seismic intensity are given higher priority.

[0076] As a result, the waterway facility management support system 10a allows workers to easily know which waterway facilities should be inspected as a priority in accordance with the seismic intensity distribution when an earthquake occurs, thereby enabling workers to carry out inspections quickly.

[0077] The waterway facilities management support system 10a is not limited to generating the first list, and may, for example, not generate the first list but generate a second list when an earthquake occurs.

[0078] <<Second Modification>> In the first modified example, the first list is generated based on the importance of the waterway facilities, but this is not limiting. For example, the list generation unit 180 may generate a first list in which the priorities of the malfunctioning facilities, which are waterway facilities that have malfunctioned in the past, are prioritized based on the degree of abnormality of each malfunctioning facility.

[0079] That is, the list generation unit 180 may identify defective facilities by referring to the inspection result database D111, and then generate a first list in which the priority of defective facilities with a relatively high degree of abnormality (e.g., S-1) is set high and the priority of defective facilities with a relatively low degree of abnormality (e.g., S-3) is set low.

[0080] Here, when earthquake information is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by prioritizing each of the multiple defective facilities in the waterway system based on the seismic intensity corresponding to each of the multiple defective facilities and the degree of abnormality of each of the multiple defective facilities.

[0081] In this case, the list generation unit 180 may generate a second list by prioritizing each of the multiple defective facilities based on the total change value obtained by multiplying the seismic intensity and abnormality degree (e.g., normalized value) corresponding to each of the multiple defective facilities by a weighting factor.

[0082] As a result, when an earthquake occurs, the waterway facility management support system 10a appropriately sets inspection priorities for defective facilities that are particularly prone to malfunctions based on the seismic intensity distribution, thereby enabling workers to carry out inspections quickly.

[0083] <<Third Modification>> Furthermore, the list generating unit 180 may generate a first list in which priorities are assigned based on, for example, the importance of each malfunctioning facility, which is a waterway facility that has malfunctioned in the past, and the degree of abnormality of each malfunctioning facility.

[0084] Here, when earthquake information is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by prioritizing each of the multiple defective facilities based on the importance and degree of abnormality of each of the multiple defective facilities and the seismic intensity corresponding to each of the multiple defective facilities.

[0085] In this case, the list generation unit 180 may generate a second list by prioritizing each of the multiple defective facilities based on the total change value obtained by multiplying the importance, abnormality degree, and seismic intensity (e.g., normalized values) corresponding to each of the multiple defective facilities by a weighting factor.

[0086] As a result, the waterway facility management support system 10a can set inspection priorities for defective facilities that are particularly prone to malfunction depending on the seismic intensity distribution when an earthquake occurs, taking into account their importance and degree of abnormality, thereby enabling workers to carry out inspections quickly.

[0087] <<Fourth Modification>> Furthermore, the list generating unit 180 may generate a first list in which the first defective facilities that are in a predetermined positional relationship with the position of the terminal device 200 are prioritized based on the importance of each of them.

[0088] Here, when earthquake information is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by prioritizing each of the first defective facilities based on the importance of each of the multiple first defective facilities identified by the defective facility identification unit 130 based on the position of the terminal device 200 and the seismic intensity corresponding to each of the first defective facilities.

[0089] In this case, the list generation unit 180 may generate the second list by prioritizing each of the first defective facilities based on the total change value obtained by multiplying the importance and seismic intensity (e.g., normalized value) corresponding to each of the first defective facilities by a weighting factor.

[0090] As a result, when an earthquake occurs, the waterway facility management support system 10a can set inspection priorities taking into account the importance of the first defective facility, which is particularly likely to malfunction depending on the seismic intensity distribution and is located close to workers so that it can be inspected quickly, thereby enabling workers to perform inspections quickly.

[0091] <<Fifth Modification>> Furthermore, the list generating unit 180 may generate a first list in which first malfunctioning facilities that are in a predetermined positional relationship with the position of the terminal device 200 are prioritized based on the degree of abnormality of each of the first malfunctioning facilities.

[0092] In this case, when earthquake information is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by prioritizing each of the first defective facilities based on the degree of abnormality in each of the multiple first defective facilities identified by the defective facility identification unit 130 based on the position of the terminal device 200 and the seismic intensity corresponding to each of the first defective facilities.

[0093] In this case, the list generation unit 180 may generate the second list by prioritizing each of the first defective facilities based on the total change value obtained by multiplying the abnormality degree and seismic intensity (e.g., normalized value) corresponding to each of the first defective facilities by a weighting factor.

[0094] As a result, when an earthquake occurs, the waterway facility management support system 10a can set inspection priorities for the first defective facility, which is particularly prone to malfunction depending on the seismic intensity distribution and is located close to workers and can be inspected quickly, taking into account the degree of abnormality, thereby enabling workers to perform inspections quickly.

[0095] <<Sixth Modification>> Furthermore, the list generating unit 180 may generate a first list in which the priorities of the first malfunctioning facilities that are in a predetermined positional relationship with the position of the terminal device 200 are assigned based on the importance and the degree of abnormality of each of the first malfunctioning facilities.

[0096] Here, when earthquake information is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by prioritizing each of the first defective facilities based on the importance and degree of abnormality of each of the multiple first defective facilities identified by the defective facility identification unit 130 based on the position of the terminal device 200, and the seismic intensity corresponding to each of the first defective facilities.

[0097] In this case, the list generation unit 180 may generate the second list by prioritizing each of the first defective facilities based on the total change value obtained by multiplying the importance, abnormality degree, and seismic intensity (e.g., normalized values) corresponding to each of the first defective facilities by a weighting factor.

[0098] As a result, when an earthquake occurs, the waterway facility management support system 10a can set inspection priorities for the first defective facility, which is particularly prone to malfunction depending on the seismic intensity distribution and is located close to workers and can be inspected quickly, taking into account its importance and degree of abnormality, thereby enabling workers to inspect it quickly.

[0099] <<Seventh Modification>> Furthermore, in the first or sixth variant, when earthquake information for each location is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may further generate a second list by prioritizing each of the at least one defective facility (or first defective facility) indicated in the first list based on information regarding hazard maps (hereinafter referred to as "hazard map information").

[0100] Hazard map information is, for example, information made public by public institutions, and indicates the degree and extent of risk of liquefaction due to earthquakes.

[0101] In this case, the list generation unit 180 generates a second list by prioritizing each of the at least one defective facility based on modified values ​​obtained by multiplying the seismic intensity, the degree of risk of liquefaction, and / or the importance and abnormality degree corresponding to the location of the terminal device 200 and each of the at least one defective facility (or the first defective facility) by a weight (for example, a normalized value of each).

[0102] This enables the waterway management device 100 to provide workers with appropriate inspection instructions in the event of an earthquake, taking into account the importance and degree of abnormality of the defective facility, as well as the seismic intensity and the risk of liquefaction.

[0103] <<Eighth Modification>> Furthermore, in the first or seventh variant, when earthquake information for each location is acquired by the acquisition unit 120 at the time of an earthquake, the list generation unit 180 may generate a second list by changing the priority of the multiple defective facilities (or first defective facilities) indicated in the first list based on the water leakage accident rate, for example.

[0104] The water leakage accident rate is information stored in the waterway facilities database D112, for example, and is an index indicating the possibility that a waterway, which is a waterway facility, will cause a water leakage accident.

[0105] In this case, for example, the list generation unit 180 generates a second list by prioritizing each of the at least one defective facility based on a modified value obtained by multiplying a weighting factor by the location of the terminal device 200 and the seismic intensity, water leakage accident rate, and / or importance and abnormality degree corresponding to each of the at least one defective facility (or the first defective facility) (for example, a normalized value of each).

[0106] This enables the waterway management device 100 to give appropriate inspection instructions to workers when an earthquake occurs, taking into consideration the importance of defective facilities, the degree of abnormality, and the rate of water leakage accidents.

[0107] <<List notification screen T20>> Referring to FIG. 6, the list notification screen T20 including the second list will be described. FIG. 6 is a screen showing an example of the list notification screen T20. The list notification screen T20 is a screen that notifies a worker of, for example, the first list and the second list so that they can be compared. Note that FIG. 6 shows, as an example, the first list and the second list displayed so that they can be compared, but this is not limited to this. For example, the first list and the second list may each be displayed separately. In this case, the waterway management device 100a may display a selection object on the list notification screen T20 to select whether to display the first list or the second list.

[0108] As shown in FIG. 6, the list notification screen T20 includes a waterway system display area T21, a first list display area T22, and a second list display area T23.

[0109] The waterway system display area T21 is an area that displays, for example, an outline of a waterway facility in a plan view. In the waterway system display area T21, for example, each seismic intensity area may be displayed in a different color, and the current position of the terminal device 200 (position T21P in Figure 6) and each of the multiple waterway facilities (waterway facilities T21a to T21j in Figure 6) may be displayed in a distinguishable manner. This allows the waterway facilities management support system 10a to enable workers to easily understand the relationship between their position, seismic intensity, and the waterway facilities.

[0110] The first list display area T22 is an area that displays at least a part of the first list. The first list display area T22 displays defective facilities, for example, in order of increasing importance. As an example, the first list display area T22 shown in Figure 6 displays five waterway facilities in order of decreasing importance among the multiple waterway facilities in waterway system A in the first list. Specifically, waterway facility T21e, waterway facility T21f, waterway facility T21g, waterway facility T21h, and waterway facility T21i are displayed in the first list.

[0111] The second list display area T23 is an area that displays at least a part of the second list. The second list display area T23 displays in the second list waterway facilities prioritized based on predetermined conditions when an earthquake occurs. As an example, the second list display area T23 in Figure 6 displays in the second list the five waterway facilities among the multiple waterway facilities in waterway system A in descending order of the above-mentioned change value, specifically waterway facilities T21b, T21c, T21a, T21g, and T21e.

[0112] In this way, the second list can display waterway facilities included in areas with high seismic intensity with a high priority. This enables the waterway facilities management support system 10a to provide appropriate inspection instructions to workers in the event of an earthquake, taking into account the importance and seismic intensity of the waterway facilities.

[0113] In the above, the term "waterway facility" may be read as "faulty facility" or "first faulty facility." In other words, the waterway facility management support system 10a may display a first list and a second list in the list display area T22 and the second list display area T23 for faulty facilities that have previously experienced a fault, or for first faulty facilities that are in a predetermined positional relationship with the terminal device 200.

[0114] ===Terminal Device 200=== Returning to FIG. 1, the functional configuration of the terminal device 200 will be described. As shown in FIG. 1, the terminal device 200 may include functional units, such as a memory unit 210, a transmission / reception unit 220, a display processing unit 230, and an operation unit 240. The functional units are functions realized, for example, by the processor 1001 reading out a program stored in the memory 1002. The memory unit 210 stores various information. The transmission / reception unit 220 transmits and receives various information (e.g., location information and inspection result information) to and from the waterway management device 100. The display processing unit 230 displays information on the screens transmitted from the waterway management device 100 (a defective facility notification screen T10, a list notification screen T20) on the display unit. The operation unit 240 receives operational input from an operator and transmits information corresponding to the operational input to the waterway management device 100 via the transmission / reception unit 220.

[0115] ===Processing Procedure=== Next, the processing procedure of the waterway facilities management support system 10 will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the processing procedure of the waterway facilities management support system 10.

[0116] In Figure 7, as an example, the processing procedure of the waterway facilities management support system 10 is described when, while an operator is inspecting the waterway system A, as shown in Figure 4, he is notified of a first defective facility T11b and also of second defective facilities T11c and T11d, and then an earthquake occurs as shown in Figure 6. For convenience, the following description will be given assuming that the list generation unit 180 provided in the waterway facilities management support system 10a (waterway management device 100a) relating to the modified example is provided in the waterway facilities management support system 10 (waterway management device 100).

[0117] In step S100, the terminal device 200 receives operational input from the worker and generates inspection result information. The terminal device 200 transmits the inspection result information to the waterway management device 100. The terminal device 200 may also periodically transmit terminal position information to the waterway management device 100. At this time, the terminal device 200 notifies the worker of the current position in the waterway system A by, for example, displaying the waterway system display area T11 of the defective facility notification screen T10 shown in FIG. 4 on the display unit.

[0118] In step S101, when the waterway management device 100 acquires, for example, inspection result information, it refers to the inspection result database D111 and transmits first defective facility information to the terminal device 200 based on the terminal location information and the defective facility location information.

[0119] In step S102, the terminal device 200 displays the first defective facility information in the first defective facility display area T12. At this time, the terminal device 200 may display the past inspection results and facility specifications of the defective facility T11b, which is the first defective facility displayed in the first defective facility display area T12, so that the worker can view them (for example, links to the inspection result database D111 and the waterway facility database D112) ("T11b inspection results.PDF" and "T11b specifications.PDF" in FIG. 4).

[0120] In step S103, when the waterway management device 100 acquires inspection result information, for example, it refers to the inspection result database D111 and the waterway facility database D112 to determine whether the abnormality degree of the first defective facility satisfies a predetermined condition. Here, the predetermined condition is a condition that the abnormality degree has worsened compared to the previous abnormality degree.

[0121] If the predetermined condition is met (step S103: YES), the waterway management device 100 transmits second defective facility information (information on a waterway facility similar to the first defective facility) to the terminal device 200 in step S104.

[0122] If the specified conditions are not met (step S103: NO), the waterway management device 100 does not send the second defective facility information to the terminal device 200, and if further inspection result information is obtained from the terminal device 200, it executes processing from step S101.

[0123] In step S105, the terminal device 200 displays the second defective facility information in the second defective facility display area T13. At this time, the terminal device 200 may display the past inspection results and facility specifications of the defective facilities T11c and T11d, which are the second defective facilities displayed in the second defective facility display area T13, so that the worker can view them (for example, links to the inspection result database D111 and the waterway facility database D112) as shown in Fig. 4 ("T11c inspection results.PDF", "T11c specifications.PDF", "T11d inspection results.PDF", and "T11d specifications.PDF" in Fig. 4).

[0124] In step S200, the waterway management device 100, for example, refers to the inspection result database D111 to generate a first list in which a plurality of first defective facilities are prioritized based on the degree of abnormality (as will be described in the processing of the fifth modified example above as an example). The waterway management device 100 transmits the first list to the terminal device 200.

[0125] In step S201, the terminal device 200 displays the first list on the list notification screen T20.

[0126] In step S202, the waterway management device 100 acquires earthquake information from a predetermined system.

[0127] In step S203, the waterway management device 100 refers to the inspection result database D111 and generates a second list (see FIG. 6) in which defective facilities in a specified waterway system (waterway system A in FIG. 6) are prioritized based on the terminal location information, earthquake information, and abnormality level. The waterway management device 100 transmits the second list to the terminal device 200.

[0128] In step S203, the waterway management device 100 may generate a second list in which only the multiple malfunctioning facilities that are the first malfunctioning facilities are ranked.

[0129] In step S204, the terminal device 200 displays the list notification screen T20 on the display unit so that the second list can be compared with the first list.

[0130] ===Hardware Configuration=== The hardware configuration of the waterway management device 100 and the terminal device 200 will be described with reference to Fig. 8. Fig. 8 is a diagram showing an example of the hardware configuration.

[0131] As shown in FIG. 8, the computer 1000 includes a processor 1001, a memory 1002, a storage device 1003, an input I / F unit 1004, a data I / F unit 1005, a communication I / F unit 1006, and a display device 1007.

[0134] The storage device 1003 is a non-volatile storage medium such as a hard disk drive (HDD), flash memory, etc. The storage device 1003 stores an operating system and various programs for realizing the above-mentioned components.

[0135] The input I / F unit 1004 is a device for receiving input from a user. Specific examples of the input I / F unit 1004 include a keyboard, a mouse, a touch panel, various sensors, and a wearable device. The input I / F unit 1004 may be connected to the computer 1000 via an interface such as a USB (Universal Serial Bus).

[0136] The data I / F unit 1005 is a device for inputting data from outside the computer 1000. A specific example of the data I / F unit 1005 is a drive device for reading data stored in various storage media. The data I / F unit 1005 may be provided outside the computer 1000. In this case, the data I / F unit 1005 is connected to the computer 1000 via an interface such as a USB.

[0137] The communication I / F unit 1006 is a device for performing data communication via the Internet N, either wired or wirelessly, with devices external to the computer 1000. The communication I / F unit 1006 may be provided external to the computer 1000. In this case, the communication I / F unit 1006 is connected to the computer 1000 via an interface such as a USB.

[0138] The display device 1007 is a device for displaying various types of information. Specific examples of the display device 1007 include a liquid crystal display, an organic EL (Electro-Luminescence) display, and a display of a wearable device. The display device 1007 may be provided outside the computer 1000. In this case, the display device 1007 is connected to the computer 1000 via, for example, a display cable. Furthermore, when a touch panel is adopted as the input I / F unit 1004, the display device 1007 can be configured as an integral part of the input I / F unit 1004.

[0139] ===Summary=== <1> The waterway facilities management support system 10 according to this embodiment comprises an acquisition unit 120 (location information acquisition unit) that acquires terminal location information indicating the location of the terminal device 200 of a worker inspecting waterway facilities in a specified waterway system, a defective facility identification unit 130 that, when operation information (information) indicating that operation input to the terminal device 200 by the worker has been received from the terminal device 200, identifies a first defective facility, which is at least one defective facility that is in a specified positional relationship with the location of the terminal device 200, based on the terminal location information and defective facility location information indicating the location of a defective facility, which is a waterway facility that has previously experienced an abnormality, and a notification unit 170 that notifies the terminal device 200 of the first defective facility information regarding the first defective facility. This enables the waterway facilities management support system 10 to achieve efficient preventive maintenance and stock management of waterway facilities.

[0140] <2> The waterway facilities management support system 10 according to this embodiment further includes an abnormality degree identification unit 140 that identifies the abnormality degree, which is a parameter indicating the degree of abnormality of the first defective facility, and an abnormality degree determination unit 150 that determines whether the abnormality degree of each of at least one of the first defective facilities satisfies a predetermined condition. The notification unit 170 notifies the terminal device 200 of the first defective facility information regarding the defective facility that is determined to satisfy the predetermined condition. This enables the waterway facilities management support system 10 to, for example, ensure that workers properly inspect the defective facility during inspections. Furthermore, the waterway facilities management support system 10 can provide workers with information indicating the specifications of the defective facility and changes in the abnormal state during inspections, thereby ensuring that workers perform appropriate inspection work.

[0141] <3> The waterway facilities management support system 10 according to this embodiment further includes a similar facility identification unit 160 that identifies a second defective facility, which is at least one waterway facility in a specified waterway system that has specifications similar to those of the first defective facility and that has previously experienced an abnormality, and the notification unit 170 notifies the terminal device 200 of second defective facility information, which is information relating to the second defective facility. This enables the waterway facilities management support system 10 to allow workers to check past abnormalities in waterway facilities similar to the waterway facility being inspected, thereby enabling preventive maintenance such as increasing the frequency of inspections of similar waterway facilities.

[0142] <4> In the waterway facilities management support system 10 according to this embodiment, the similar facility identification unit 160 identifies whether a first abnormality degree, which is the degree of abnormality at a first time point in the past for each of at least one first defective facility, has worsened compared to a second abnormality degree, which is the degree of abnormality at a second time point earlier than the first time point for each of at least one first defective facility, and the notification unit 170 notifies the terminal device 200 of second defective facility information relating to the defective facility identified as having a worsening degree of abnormality. As a result, when the abnormal condition of the first defective facility worsens, the waterway facilities management support system 10 can determine that the abnormal condition of similar facilities where abnormalities are occurring is also likely to worsen, automatically extract the similar facilities, and notify workers of information about the similar facilities, thereby enabling preventive maintenance such as increasing the frequency of inspections of similar waterway facilities.

[0143] <5> The waterway facilities management support system 10 according to this embodiment further includes a similar facility identification unit 160 that identifies whether a first abnormality degree, which is the degree of abnormality at a first time point in the past for each of at least one first defective facility, has worsened compared to a second abnormality degree, which is the degree of abnormality at a second time point earlier than the first time point for each of at least one first defective facility, and identifies waterway facilities in a specified waterway system that have specifications similar to the specifications of the defective facility identified as having a worsening degree of abnormality, and a notification unit 170 notifies the terminal device 200 of facility information that is information about the waterway facilities identified by the similar facility identification unit 160. Thus, when the abnormal condition of the first defective facility is worsening, the waterway facilities management support system 10 can determine that the abnormal condition of similar facilities similar to the first defective facility is also likely to be worsening, automatically extract the similar facilities, and notify workers of information about the similar facilities, enabling preventive maintenance such as increasing the frequency of inspections of similar waterway facilities.

[0144] <6> The waterway facilities management support system 10 according to this embodiment further includes an acquisition unit 120 (inspection result information acquisition unit) that acquires inspection result information indicating the results of workers' inspections of waterway facilities from the terminal device 200, and when the defective facility identification unit 130 acquires the inspection result information, it identifies a first defective facility that is in a predetermined positional relationship with the location of the terminal device 200. This enables the waterway facilities management support system 10 to achieve efficient preventive maintenance and stock management of waterway facilities.

[0145] <7> The waterway facilities management support system 10a according to this embodiment further comprises a list generation unit 180 that generates a first list in which each of a plurality of malfunctioning facilities, which are first malfunctioning facilities, is ranked based on the degree of abnormality of each of the malfunctioning facilities, and an acquisition unit 120 (earthquake information acquisition unit) that acquires earthquake information including information indicating the current seismic intensity for each location from a predetermined system, and when the list generation unit 180 acquires earthquake information, it generates a second list in which the malfunctioning facilities in a predetermined waterway system are ranked based on the earthquake information and the degree of abnormality of each of the plurality of malfunctioning facilities in the predetermined waterway system, and the notification unit 170 notifies the terminal device 200 of the first list and the second list so that they can be compared.
