Description

[Technical Field]

[0001] The present invention relates to a maintenance management support system used to manage deformation of structures. [Background technology]

[0002] Infrastructure structures, such as concrete structures and tunnel structures, require proper maintenance. In particular, maintenance work requires the proper detection, recording, and repair of any deterioration in the performance of a structure from its ideal healthy state (known as "deformation"), such as cracks, peeling or loosening of concrete, or water leaks.

[0003] There are various methods for detecting abnormalities in structures, including visual inspection, in which the structure is visually inspected to detect any abnormalities; tapping inspection, in which the structure is tapped with a designated tool and the sound produced is used to check for any abnormalities; and inspection methods in which the structure is photographed, the captured image information is visually inspected, and the areas where there are abnormalities are extracted.

[0004] Visual inspections and hammering inspections require going to the structure and conducting the work, which takes time. For this reason, the method often used is to photograph the structure and extract the abnormalities from the photographed image information.

[0005] In the case of inspection methods that use image information, the person in charge visually checks the photographed image information of the structure to visually identify any abnormalities. Then, for the abnormalities identified during the tracing work, information indicating the existence of abnormalities (hereinafter referred to as "deformation information") is added to the CAD data that manages the abnormalities (deformation tracing data) (this is called tracing work). The deformation tracing data is used to create a repair plan for the structure, and the actual repair work is carried out based on the repair plan.

[0006] An example of such a computer system is shown in Non-Patent Document 1 below. [Prior art documents] [Non-patent literature]

[0007] [Non-Patent Document 1] Sankyo Engineering Co., Ltd., "Crack Draw21", [online], Internet<URL:http: / / www.sankyo-eng.com / crackdraw.html> Summary of the Invention [Problem to be solved by the invention]

[0008] The inspection method using image information can be realized by using a computer system such as that shown in Non-Patent Document 1.

[0009] On the other hand, when managing deformation of a structure, it is not enough to simply look at the CAD data that manages the deformation; it is necessary to simultaneously compare photographed images of the structure (for example, a tunnel wall), deformation development diagrams, inspection data, specification data, etc., and decide whether to repair the deformed areas.

[0010] However, in the past, it was necessary to launch separate software for each purpose, such as using an image viewer for photographed images of structures, CAD software for deformation development diagrams, an inspection system for inspection data, and spreadsheet software for specification data, and to make judgments while looking at the individual displays provided by each software. In other words, there was no unified way to view each piece of data, and each piece had to be handled using separate software, which resulted in a heavy workload. [Means for solving the problem]

[0011] In view of the above problems, the inventors have invented a maintenance management support system that can display various data in a unified manner when managing structural deformation.

[0012] The first invention is a maintenance management support system used for the maintenance management of a structure, the maintenance management support system having a data storage unit that stores structure images and deformation development diagrams, and a detailed information display processing unit that displays the structure images and deformation development diagrams in an overlapping manner, and the detailed information display processing unit: The structure image and the deformation development diagram are superimposed and displayed in a first display area, and the display range of the structure image and the deformation development diagram is displayed in a second display area, and the second display area has a scale that indicates the display range using the distance from a reference position and a display area for information on the section in the display range, This is a maintenance management support system that displays the structure image and the deformation development diagram in conjunction with each other.

[0013] By configuring the present invention, it is possible to display structure images and deformation development diagrams in conjunction with each other for managing structure deformation. This improves usability because structure images and deformation development diagrams, which were previously displayed separately, can now be displayed in conjunction with each other.

[0014] In the above-mentioned invention, the data storage unit further stores inspection data of the deformation in the deformation development diagram, and the detailed information display processing unit can be configured as a maintenance work support system that displays the inspection data of the deformation in conjunction with the structure image and / or the deformation development diagram.

[0015] As shown in this invention, by displaying the inspection data of the deformation in conjunction with the image of the structure and the development diagram of the deformation, the inspection data that was previously displayed separately can be displayed in conjunction with the image of the structure and the development diagram of the deformation. This allows for a unified view, improving usability.

[0016] In the above-mentioned invention, the data storage unit further stores repair data for the deformation in the deformation development diagram, and the detailed information display processing unit can be configured as a maintenance work support system that displays the repair data for the deformation in conjunction with the structure image and / or the deformation development diagram.

[0017] As shown in the present invention, by displaying the repair data of the deformation in conjunction with the data, it is possible to display information on the repair of the deformation in conjunction with the data. This allows for a unified view, improving usability.

[0018] In the above-mentioned invention, the data storage unit further stores data on the number of deformations, and the detailed information display processing unit can be configured as a maintenance work support system that displays the number of deformations in conjunction with the structure image and / or the deformation development diagram.

[0019] As shown in this invention, by also displaying data on the number of deformations in conjunction with the image of the structure and the development of the deformation, which was previously displayed separately as statistical data on the number of deformations, it is possible to display them in conjunction with the image of the structure and the development of the deformation. This improves usability by providing a unified view.

[0020] In the above-mentioned invention, the structure image, the deformation development diagram, the deformation inspection data, the deformation repair data, and the number of deformations are associated in the same coordinate system, and the system can be configured as a maintenance work support system that identifies and displays the display range using the position and / or time axis in the coordinate system.

[0021] By associating structural images, deformation development diagrams, deformation inspection data, and the number of deformations in a unified coordinate system as in the present invention, these can be displayed in a linked manner.

[0022] In the above-mentioned invention, the structure image, the deformation development diagram, the deformation inspection data, and the number of deformations have different coordinate systems, and can be configured as a maintenance work support system in which each coordinate system is converted into the same coordinate system using a conversion formula, and the display range is identified and displayed using the position in the converted same coordinate system.

[0023] When structure images, deformation diagrams, deformation inspection data, and the number of deformations are managed using separate coordinate systems, they can be displayed in a linked manner by using conversion formulas for each coordinate system to associate them in a unified coordinate system, as in the present invention.

[0024] In the above-mentioned invention, the same coordinate system can be configured as a maintenance management work support system using distance from a reference position or latitude and longitude.

[0025] There are various possible coordinate systems, but considering actual business operations, it is best to use the distance from a reference position as in the present invention. For example, in the case of railways, including subways, and roads, distance markers are already installed, so it is highly convenient to manage the distance from these markers. Furthermore, if latitude and longitude are used as location information, the accuracy of the location information can be improved by acquiring the location information using GPS or the like, and it can also be expanded to a three-dimensional coordinate system.

[0027] In the above-mentioned invention, the detailed information display processing unit displays a third display area that allows the user to select the type of deformation in the deformation development diagram superimposed on the structure image, The type of deformation selected The system can be configured as a maintenance management support system that displays the deformation of the layer according to the deformation on the image of the structure in a deformation development diagram.

[0028] In the above-mentioned invention, the detailed information display processing unit 1st The system can be configured as a maintenance work support system in which inspection data and / or repair data for deformations within the display range of the display area, or within the range specified in the structure image or the deformation development diagram, are displayed in a fourth display area.

[0029] In the above-mentioned invention, the detailed information display processing unit can be configured as a maintenance work support system that displays the number of deformations according to the distance from a reference position in a fifth display area, depending on the display range of the first display area.

[0030] In order to display detailed information for maintaining and managing a structure, it is preferable that the detailed information display processing section be provided with a display area as in these inventions.

[0031] In the above-mentioned invention, a part or all of the data stored in the data storage unit is associated with date information, and the detailed information display processing unit: Detailed information display screen The system can be configured as a maintenance and management support system that has a period input area for inputting the period to be displayed, and displays data corresponding to the period input in the period input area.

[0032] When managing the deterioration of a structure, there is a demand for searching not only information on the current deterioration, but also for searching for measures against similar deterioration events, such as what kind of deterioration has occurred in the past and what kind of repair work has been carried out in the past for similar deterioration. Therefore, by being able to input a period as in this invention, it is also possible to check information on past deterioration and repairs.

[0033] In the above-mentioned invention, the detailed information display processing unit can be configured as a maintenance work support system that displays a structure image, a deformation development diagram, or the number of deformations in correspondence with a scale indicating the distance from a reference position, and changes and displays the scale by changing the display range of the structure image, deformation development diagram, or the number of deformations.

[0034] By configuring the system as in the present invention, it is possible to display structure images, deformation development diagrams, and the number of deformations in conjunction with each other.

[0035] The maintenance management work support system of the first invention can be realized by loading the maintenance management work support program of the present invention into a computer and executing it. Structure images A maintenance management work support program that functions as a detailed information display processing unit that superimposes a deformation development diagram and a detailed information display processing unit, wherein the detailed information display processing unit: The structure image and the deformation development diagram are superimposed and displayed in a first display area, and the display range of the structure image and the deformation development diagram is displayed in a second display area, and the second display area has a scale that indicates the display range using the distance from a reference position and a display area for information on the section in the display range, This is a maintenance management support program that displays the structure image and the deformation development diagram in conjunction with each other. [Effects of the Invention]

[0036] By using the maintenance management support system of the present invention, when managing the deformation of a structure, each piece of data can be displayed in a linked and unified manner. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0038] An example of the overall system configuration of the maintenance management work support system 1 of the present invention is shown in FIG. 1, and an example of the hardware configuration of a computer used in the maintenance management work support system 1 is shown in FIG.

[0039] The maintenance and management work support system 1 of the present invention uses a control terminal 2. The control terminal 2 in the maintenance and management work support system 1 is realized using a computer. Fig. 2 shows an example of the hardware configuration of a computer. The computer has a calculation device 70 such as a CPU that executes the calculation processing of a program, a storage device 71 such as a RAM or hard disk that stores information, a display device 72 such as a display that displays information, an input device 73 such as a keyboard or mouse that can input information, and a communication device 74 that sends and receives the processing results of the calculation device 70 and the information stored in the storage device 71 via a network such as the Internet or a LAN.

[0040] If the computer is equipped with a touch panel display, the display device 72 may be integrally configured with the input device 73. Touch panel displays are often used in portable communication terminals such as tablet computers and smartphones, but are not limited to these.

[0041] The touch panel display is a device that integrates the functions of the display device 72 and the input device 73 in that input can be made directly on the display using a specified input device (such as a touch panel pen) or a finger.

[0042] In the following explanation, the structure will be described as a subway tunnel, but it is not limited to this and may also be a road tunnel or other infrastructure structure.

[0043] The control terminal 2 has a data storage unit 20 , a display processing unit 21 , and a registration processing unit 22 .

[0044] The data storage unit 20 stores data necessary for managing deformation of a structure, and includes, for example, a photographed image storage unit 200, an inspection data storage unit 201, a specification data storage unit 202, a deformation development diagram storage unit 203, a risk assessment data storage unit 204, a section data storage unit 205, a repair data storage unit 206, ancillary object data storage unit 207, and an associated file storage unit 208. Note that the data storage unit 20 does not need to have all of these data, and it is sufficient to have one or more of them within the required range.

[0045] The photographed image storage unit 200 stores image data (structure images) of the surface of a structure for creating a deformation development diagram, which will be described later. For example, this is image data of the entire tunnel wall (left and right side walls, upper floor). As an example of photographed image data, an example of image data of the entire tunnel wall is shown schematically in Figure 4. In this case, the horizontal direction is the kilometer direction, and the vertical direction is the tunnel cross-sectional direction. The structure images are stored in association with the distance from a reference position, latitude, longitude, altitude, etc.

[0046] To capture the entire tunnel wall, for example, a trolley is placed on the tracks of a subway tunnel section, and several imaging devices, such as digital cameras, are installed on the trolley, evenly oriented radially toward the wall. Each imaging device then takes an image. By combining these images, image data can be captured across the tunnel. However, since this is only a portion of the entire tunnel wall, the tunnel wall is combined to form a single large panoramic image, resulting in image data of the entire tunnel wall, with the horizontal direction being the kilometer direction and the vertical direction being the tunnel transverse direction. Note that since a single panoramic image would require an extremely large data size, it is also possible to use a processing method called a Tile Map Service, which manages large images and display areas. In this case, the panoramic image is divided into squares of a certain size, for example, 256 x 256 pixels (the divided image data is called tile image data), and the tile image data is arranged seamlessly. Furthermore, a predetermined number of tiles, for example 2 x 2 tiles (512 x 512 pixels), are reduced to a predetermined size (for example 50%) to create tile image data at a scale reduced by one step, and this is repeated recursively to create a database of photographed image data (photographed image storage unit 200). Note that known technology may be used as the tile map service.

[0047] The inspection data storage unit 201 stores data on structure deformation inspections. For example, the deformation inspection data stores the degree of damage, called the deformation rank, for deformations such as cracks, water leaks, peeling, spalling, exposed rebar, junks, and cold joints on tunnel walls, along with the location of the deformation, in association with the distance from a reference position, latitude, longitude, altitude, and other parts of the structure (left and right side walls, upper floor, etc.). The degree of damage is evaluated, for example, in descending order of damage, such as A>B>C. Image data of photographs of the deformation (deformation image data) may also be stored in association with the data. The inspection data may also be stored in association with information on the date (year, month, and day) on which the inspection was performed.

[0048] The specification data storage unit 202 stores specification data related to the structure itself, such as the construction method, length, contractor, construction year, and construction area. If the structure is a tunnel, construction methods include open cut and shield. A construction area is a section unit for tunnel construction work. The specification data is stored in association with the distance from a reference position, latitude, longitude, altitude, etc.

[0049] The deformation development diagram storage unit 203 stores deformation development diagrams. Deformation development diagrams are data that are created by tracing deformations shown in photographed images of the surface of a structure as graphic data. In the deformation development diagram storage unit 203, deformations are stored as graphic data in a development diagram of the entire surface of the structure, for example, in the form of CAD data. Deformation development diagrams are stored in association with the distance from a reference position, latitude, longitude, altitude, etc. It is also preferable that the deformation development diagrams be stored in association with information on the date (year, month, day) on which the deformation was recorded.

[0050] If the structure is a tunnel, the entire tunnel wall (left and right side walls, upper floor) is unfolded, and the deformations shown on each are stored as graphic data. The drawings of the deformation unfolded diagram are divided into layers according to the type of deformation.

[0051] The risk assessment data storage unit 204 uses photographed image data of the structure and a development view of the deformation to score risk factors such as the number of deformations, area, and the presence or absence of intersecting deformations where multiple types of deformations exist in the same location for each area of ​​a predetermined size on the surface of the structure, for example, 1 x 1 meter, using a predetermined method, and stores the score as risk assessment data. A heat map may be created by coloring according to the score of the risk assessment data. The risk assessment data is stored in association with the distance from the reference position, latitude, longitude, altitude, etc.

[0052] The section data storage unit 205 stores section data. The section data is data obtained by scoring estimated values ​​of predicted deformation occurrences using predetermined factors such as the number of deformations per predetermined distance, the number of deformations per type per predetermined distance, and the presence or absence of deformations of types that have not occurred in the surrounding area, using a predetermined method. Sections with high scores can be determined as sections requiring caution. The section data is stored in association with the distance from the reference position, latitude, longitude, altitude, etc.

[0053] The repair data storage unit 206 stores data on repairs to structural deformations. For example, the repair data may include information such as the repair method for the deformation, the repair date and time, and the contractor that performed the repair. The repair data is stored in association with the deformation for which the repair was performed, such as the distance from the reference position, latitude, longitude, and altitude.

[0054] The accessory data storage unit 207 stores data related to objects attached to a structure. If the structure is a subway tunnel, examples of accessories include electric wires, fluorescent lights, and ventilation facilities. The accessory data stores the type of accessory, manufacturer, installation date, installation company, etc. The accessory data is stored in association with the distance from a reference position, latitude, longitude, altitude, etc.

[0055] The related file storage unit 208 stores related files such as documents recording construction records and presentation files in association with the distance from a reference position, latitude, longitude, altitude, and the like.

[0056] The display processing unit 21 includes a management target information display processing unit 210 , a map display processing unit 211 , and a detailed information display processing unit 212 .

[0057] The management object information display processing unit 210 displays information showing the entire management object, such as a railway route map or a road map, on a predetermined display device 72. In the case of a subway, a list of all routes operated by the subway operating organization is displayed, and when a station name on a route map showing each route is selected, the detailed information display processing unit 212, which will be described later, displays detailed information about structures near the selected station name. Figure 5 shows an example of a route map display screen 3 that displays a route map as a diagram showing the entire management object. When the diagram showing the entire management object is an expressway, for example, the names of the expressway, interchanges, service areas, parking areas, junctions, etc. are displayed.

[0058] The map display processing unit 211 displays marks (e.g., pins) for displaying detailed information about structures on a map representing a space on a predetermined display device 72. When the mark is selected, the detailed information display processing unit 212, which will be described later, displays detailed information about structures near the selected mark. The marks are preferably arranged along routes, roads, etc. on the map. Figure 6 shows an example of the map display screen 4.

[0059] The detailed information display processing unit 212 displays detailed information about the structure on a predetermined display device 72. An example of the detailed information display screen 5 is shown in Fig. 7. The detailed information display screen 5 has a first display area 51 to a fifth display area 55.

[0060] The first display area 51 displays a structure image stored in the captured image storage unit 200, for example, an image of a tunnel wall. In the first display area 51, the structure image can be seamlessly scrolled and zoomed in and out for display. In the first display area 51, the horizontal direction is the direction of travel from the reference position, and the vertical direction is the tunnel crossing direction, but this is not limited to this. In addition, a deformation development diagram stored in the deformation development diagram storage unit 203 may be superimposed on the structure image. Furthermore, a heat map colored according to the score of the risk assessment data stored in the risk assessment data storage unit 204 may be superimposed on the structure image.

[0061] The second display area 52 displays a scale 520 that indicates the position from the reference point. If the structure is a subway tunnel, a distance marker (kilometers) is displayed as the scale 520. The position of the second display area 52 and the structure image and deformation development map in the first display area 51 are each associated with the position from the reference point displayed in the second display area 52. For example, if the scale 520 is kilometers, the structure image and deformation development map displayed in the first display area 51 are each associated with kilometers, and each image is stored in each memory unit.

[0062] In addition to the scale 520, the second display area 52 may also display information indicating the type of section the position corresponds to. For example, the second display area 52 of the detailed information display screen 5 in FIG. 7 displays the specification data stored in the specification data storage unit 202, such as the managed section, the work section, and the specific deformation occurring section. The managed section display area 521 indicates which managed section the structure image displayed in the first display area 51 belongs to. The managed section may be any unit of management by the operator managing the structure, such as, but not limited to, between stations. The work section display area 522 indicates which work section the structure image displayed in the first display area 51 belongs to. The work section may be any unit in which work on the structure is performed, such as, but not limited to, a construction section. The specific deformation occurring section display area 523 indicates whether the section is a section for managing a specific deformation of the structure displayed in the first display area 51. The specific deformation can be determined arbitrarily, but salt damage is an example of a specific deformation. It is preferable that information be displayed as a pop-up message when the mouse or the like is placed on each display area, but this is not limiting and information may also be displayed as text, for example. A period input area 524 may also be displayed in the second display area 52. The period input area 524 adjusts the time axis of the deformation displayed in the deformation development diagram in the first display area 51. For example, if the period input area 524 is set to 2010 to 2021, and 2020 is set as the start date and 2021 as the end date, the deformation development diagram will display the deformation from 2020 to 2021.

[0063] In the position input area 525 of the second display area 52, the position of the structure image to be displayed in the first display area 51 is input. When a position (distance from the reference position) is input in the position input area 525, the structure image, deformation development diagram, etc. corresponding to that position are displayed in the first display area 51.

[0064] The third display area 53 is used to select the type of deformation (layer) in the deformation development diagram to be superimposed on the structure image displayed in the first display area 51. For example, by selecting the type of deformation to be displayed in the deformation development diagram, such as cracks, water leakage, peeling, falling off, exposed rebar, initial defects (junks, cold joints), and repair marks, from the structure image and deformation development diagram, the deformation in the layer corresponding to that type is displayed superimposed on the structure image.

[0065] The fourth display area 54 displays detailed information about the deformation in the deformation development diagram displayed in the first display area 51. For example, as shown in FIG. 8, when an area is specified in the first display area 51, the deformation in that area is identified from the deformation development diagram storage unit 203, information about the identified deformation is extracted from the inspection data storage unit 201, and repair data for repairing the identified deformation information is extracted from the repair data storage unit 206, and the deformation information and repair information are displayed in the fourth display area 54. The deformation and repair information may be displayed in a list according to a predetermined standard, for example, in chronological order. When deformation information displayed in the fourth display area 54 is selected, detailed information about the deformation is displayed. An example of the deformation detailed information screen 6 is shown in FIG. 9. The deformation detailed information screen 6 in FIG. 9 displays detailed information about the deformation stored in the inspection data storage unit 201, such as the type of deformation 601, the position where the deformation occurred 602, the distance from the reference position 603, the degree of damage to the deformation 604, and deformation image data 605. Furthermore, if there is a record of repair for the deformation, the repair data for the deformation stored in the repair data storage unit 206 is displayed. Furthermore, if there is a record of the construction work for the repair, related files such as construction records are extracted from the related file storage unit 208 and displayed.

[0066] The fifth display area 55 displays a graph of predetermined numerical values, such as the number of deformations within the range of the structure image displayed in the first display area 51. At this time, the graph is displayed according to the scale 520 (position from the reference point) of the second display area 52. In other words, the number of deformations for each position from the reference point is displayed in a graph. The data to be displayed in a graph may be extracted and displayed from data stored in the risk assessment data storage unit 204, the section data storage unit 205, etc.

[0067] The detailed information display processing unit 212 displays the information to be displayed in the first display area 51 and the fifth display area 55 of the detailed information display screen 5 within a range corresponding to the distance from the reference position displayed in the second display area 52. This allows the structure image, deformation development diagram, and detailed deformation information at the same position to be viewed on a single screen, improving usability when maintaining and managing a structure.

[0068] Although not shown on the detailed information display screen 5 in Fig. 7, information on the attachments of the structure may be displayed instead of the structure itself. In this case, the attachment data is extracted from the attachment data storage unit 207, and the information is displayed.

[0069] The detailed information display processing unit 212 not only displays each piece of data stored in the data storage unit 20 as is on the detailed information display screen 5, but also performs predetermined processing on each piece of data stored in the data storage unit 20, such as statistical processing, tile processing, data selection processing, search processing using search queries or condition settings, and calculation processing, before displaying it.

[0070] The registration processing unit 22 accepts registration of position information such as distance from a reference position (relative coordinates), latitude, longitude, and altitude (absolute coordinates) for various data to be stored in the data storage unit 20, and stores the information in association with each data item in the data storage unit 20. An example of the distance from the reference position is a distance marker. The distance marker may be a physical distance marker or a digital distance marker. By accepting registration from relative coordinates or absolute coordinates by the registration processing unit 22, each piece of data, such as the structure image stored in the photographed image storage unit 200, the deformation inspection data stored in the inspection data storage unit 201, the specification data stored in the specification data storage unit 202, the deformation development map stored in the deformation development map storage unit 203, the risk assessment data stored in the risk assessment data storage unit 204, the predicted deformation estimates stored in the section data storage unit 205, the repair data stored in the repair data storage unit 206, the incidental data stored in the incidental data storage unit 207, and the related files stored in the related file storage unit 208, is associated with each other using the same coordinate system (distance from the reference position, latitude, longitude, altitude, etc.). For example, if the structure is a subway tunnel, the zero kilometer post corresponds to the reference position, but is not limited to this.

[0071] The location information associated with each data is expressed as (x,y) coordinates if it is expressed as a point, (x1,x2) if it is expressed as an interval, [(x1,y1),(x2,y2),...,(xn,yn)] if it is expressed as a line, and [(x1,y1),(x2,y2),...,(xn,yn),(x1,y1)] if it is expressed as an area (zone). The x coordinate is the distance from a reference position, and the y coordinate is the distance from the reference position of the tunnel cross section. Furthermore, when latitude, longitude, and altitude are used as location coordinates, each location can be indicated by each of the respective coordinates.

[0072] In this way, different types of data, such as structure images, deformation diagrams, and detailed deformation information, can be displayed on a single screen by relating them to the same coordinate system.

[0073] The location information may further include an xy coordinate system and latitude / longitude conversion processing. Also, by using not only the xy coordinate system but also the xyz coordinate system, it is possible to support three-dimensional display. In addition to location information, the time axis may also be taken into consideration. In other words, even for the same location, the date and time information may also be taken into consideration. This makes it possible to compare the current situation with that of one year ago at the same location. [Example]

[0074] Next, an example of the processing process of the maintenance and management work support system 1 of the present invention will be described with reference to the flowchart of FIG.

[0075] When managing the deformation of a subway tunnel, which is a structure, using the maintenance management work support system 1 of the present invention, first an overall view or a map is displayed by performing a predetermined operation on the control terminal 2. When displaying the overall view, the managed information display processing unit 210 displays the overall view or the map on a predetermined display device 72, and when displaying the map, the map display processing unit 211 displays the overall view or the map, respectively.

[0076] When an input of a location for displaying detailed information is received on the overall map displayed by the managed information display processing unit 210 or the map displayed by the map display processing unit 211, such as a selection of a station name to be displayed on a route map as an overall map, or a selection of a pin to be displayed on the map (S100, S110), the detailed information display processing unit 212 identifies the location corresponding to the selected station or pin, and identifies the display range (a range based on the distance from a reference position) based on that location (S120).

[0077] The detailed information display processing unit 212 then extracts data within the range specified in S120 from the data storage unit 20 (S130) and displays the extracted data in each display area (S140) for use in displaying in each display area of ​​the detailed information display screen 5. For example, in addition to displaying the data extracted from the data storage unit 20 in a predetermined display area, it also performs predetermined data processing on the data extracted from the data storage unit 20 and displays the processing results in a predetermined display area.

[0078] For example, a structure image (tunnel wall surface image) within the range specified in S120 is extracted from the captured image storage unit 200 and displayed in the first display area 51 of the detailed information display screen 5. Also, a deformation development view for the range specified in S120 is extracted from the deformation development view storage unit 203 and displayed superimposed on the tunnel wall surface image. At this time, the deformation to be superimposed is changed based on the layer of the deformation type selected in the third display area 53. Furthermore, the second display area 52 displays a scale 520 for the range specified in S120, a management section display area 521, an operation section display area 522, and a specific deformation occurrence section display area 523 based on the specification data stored in the specification data storage unit 202. Also, if the structure has ancillary objects, information on the ancillary objects stored in the ancillary object data storage unit 207 is displayed.

[0079] Furthermore, the detailed information display processing unit 212 identifies deformations in the entire or specified area of ​​the first display area 51 from the deformation development diagram memory unit 203, extracts information on the deformations from the inspection data memory unit 201, and also extracts information on repairs for the deformations from the repair data memory unit 206, and displays them in a list in chronological order in the fourth display area 54.

[0080] In addition, the detailed information display processing unit 212 extracts the number of deformations within the range identified in S120 from the data stored in the risk assessment data storage unit 204, the section data storage unit 205, etc., and displays the extracted data in a graph in the fifth display area 55, corresponding to the position.

[0081] The detailed information display processing unit 212 adjusts the information to be displayed in the first display area 51 to the third display area 53 and the fifth display area 55 in accordance with the distance from the reference position of the scale 520 in the second display area 52, thereby making it possible to display multiple pieces of information together on the detailed information display screen 5.

[0082] Note that the detailed information display screen 5 may be physically one window, or each display area may be displayed in a separate window, as long as the information in each display area is displayed in association with the distance from the reference position of the scale 520 of the second display area 52. Furthermore, the display position and display content of each display area can be changed as desired.

[0083] By executing such processing, the detailed information display processing unit 212 displays the detailed information display screen 5.

[0084] The detailed information display processing unit 212 then monitors operations on the detailed information display screen 5, and upon receiving input for changing the display range, etc. (S150), it specifies the changed display range in conjunction with this (S120).The detailed information display processing unit 212 then extracts data in the range specified in S120 from the data storage unit 20 to be used for display in each display area of ​​the detailed information display screen 5 (S130), and displays the extracted data in each display area (S140).

[0085] For example, when a horizontal scroll operation of the tunnel wall image displayed in first display area 51 is detected, the x and y coordinates of the xy coordinate system to which the scroll operation moves are identified, and the display range on scale 520 of second display area 52 is changed in accordance with the scroll operation to identify the x and y coordinates of the changed display range.The detailed information display processing unit 212 then extracts data to be used for display in each display area of ​​detailed information display screen 5 from data storage unit 20, and displays it in each display area.

[0086] In addition, when the period to be displayed is changed using the period input area 524 of the second display area 52, the data to be displayed in each display area is extracted from the data storage unit 20 according to the period and displayed in each display area.

[0087] The above operations are repeated until an end operation (S110) is performed.

[0088] In the above explanation, the distance from the reference position is processed using the same coordinate system in each display area of ​​the detailed information display screen 5 displayed by the detailed information display processing unit 212, but it is also possible to use a different coordinate system for each display area and process the distance using a conversion formula for each coordinate system. In the present invention, such processing is also included in processing using the same coordinate system. [Example]

[0089] In addition to the above-described first embodiment, the data storage unit 20 may include a deformation prediction data storage unit 209. An example of the system configuration of the maintenance management work support system 1 in this case is shown in FIG.

[0090] The deformation prediction data storage unit 209 stores data related to predicted deformation progression (deformation prediction data) in association with information such as the current deformation, distance from the reference position, latitude, longitude, and altitude. Deformation prediction data includes changes in deformation size, changes in damage shape, and changes in deformation rank. The deformation prediction data may be data calculated using AI, for example. In this case, deformation information (deformation size, deformation shape (image), deformation rank, etc.) is input to a learning model in which the weighting coefficients between neurons in each layer of a neural network consisting of multiple intermediate layers are optimized, and deformation prediction data predicting future deformation, such as future deformation size, deformation shape, and deformation rank, is output as an output value. The learning model can use various information on deformations (size of deformation, shape (image) of deformation, deformation rank, etc.) and information on deformations (size of deformation, shape (image) of deformation, deformation rank, etc.) after a certain period of time has passed since the time of the deformation (for example, six months, one year, two years, three years, five years, etc.) as correct data.

[0091] The detailed information display processing unit 212 can extract the deformation prediction data stored in the deformation prediction data storage unit 209 and display the extracted deformation prediction data on the detailed information display screen 5 in association with the current deformation. For example, an image of the shape of the deformation from the deformation prediction data can be displayed superimposed on the current deformation displayed in the first display area 51. Alternatively, when displaying deformation information identified from the entire first display area 51 or a specified area in the fourth display area 54, the detailed information display processing unit 212 may display the deformation prediction data (size of deformation, deformation rank, etc.) stored in the deformation prediction data storage unit 209 in addition to the deformation information extracted from the inspection data storage unit 201 and the repair information for the deformation extracted from the repair data storage unit 206.

[0092] This allows us to visualize the progression of future damage and use it to prioritize repairs. [Industrial Applicability]

[0093] By using the maintenance management support system 1 of the present invention, when managing the deformation of a structure, each piece of data can be displayed in a linked manner, and a unified display can be achieved. [Explanation of symbols]
