  Subsequently, in the structure maintenance management system 100, the shape and deformation of the structure to be maintained are measured, the shape and deformation of the structure are associated with the absolute coordinate system, and the data is stored in the structure DB 3 and displayed. The operation of performing will be described. FIG. 2 is a flowchart showing the structure maintenance process in the structure maintenance system.

  First, in the structure maintenance management system 100, related data is input from the input unit 2 regarding the structure to be maintained (step S1). Relevant data is data other than the above-mentioned measurement data, and at the start of operation of structure maintenance management, it is data such as the contractor, year of service, traffic volume, and surrounding population. After the start of operation, data such as traffic volume, flow rate, surrounding population, repair history, and map information. Note that the types of data shown in FIG. 1 are examples, and the present invention is not limited to these. For example, repair plan, city planning information of surrounding area, environment, and weather data may be input from the input unit 2 and stored in the additional data storage unit 32. In addition, about map information, you may utilize the external data from memory | storage parts other than structure DB3. In addition, regarding the shape data of the structure to be stored in the initial data storage unit 31, data may be input from the input unit 2 when using drawing data at the time of designing the target structure.

  Next, the measurement unit 1 measures the structure to be maintained (step S2). As described above, in the measurement unit 1, the position measurement unit 11 measures the position of the structure, the shape measurement unit 12 measures the shape of the structure, and the deformation measurement unit 13 measures the deformation of the structure. . The measurement unit 1 stores the measured position, shape, and deformation data in the initial data storage unit 31 in the measurement at the start of the operation of the structure maintenance management. The measured position, shape, and deformation data are stored in the additional data storage unit 32. The position data stored in the structure DB 3 from the measurement unit 1 includes GPS coordinate data of the structure. Further, the shape data and deformation data stored in the structure DB 3 from the measurement unit 1 include time information at the time of measurement together with the measured raw data. The deformation data includes internal state data in addition to the surface state depending on the type of measuring instrument used. The inspected history, that is, the measurement history can be confirmed from the time information of the shape data and the deformation data stored in the additional data storage unit 32 of the structure DB 3. The time information may be information indicating time, and may be information on the number of times of measurement when measurement is performed periodically.

  Next, the shape development unit 41 of the inspection result calculation unit 4 develops the shape data stored in the initial data storage unit 31 or the additional data storage unit 32 of the structure DB 3 into 3D, and the deformation development unit 42 The deformed data stored in the initial data storage unit 31 or the additional data storage unit 32 of the structure DB 3 is expanded into 3D data (step S3). For example, when the deformation is cracked in the tunnel, the deformed portion corresponds to a curved portion of the tunnel in the 3D shape data of the tunnel measured simultaneously with the deformed data. In some cases, the 2D crack deformation data captured by the camera is converted to 3D according to the shape of the curved tunnel. Note that the method of expanding the deformation data described here into 3D is an example, and the present invention is not limited to this.

  As described above, when the shape and deformation data measured by the measuring unit 1 are all 3D, the data 3D processing may be omitted. The shape development unit 41 directly uses the shape data measured by the shape measurement unit 12 as 3D shape data, and the deformation development unit 42 uses the deformation data measured by the deformation measurement unit 13 as it is as 3D deformation data. .

  The shape development unit 41 stores the 3D shape data developed in 3D or the 3D shape data from the shape measurement unit 12 in the processing result data storage unit 33 of the structure DB 3. In addition, the deformation development unit 42 stores the 3D deformation data developed in 3D or the 3D deformation data from the deformation measurement unit 13 in the processing result data storage unit 33 of the structure DB 3. At this time, the shape development unit 41 and the deformation development unit 42 store the 3D shape data and the 3D deformation data in association with the position data acquired at the time of measurement (step S4). As a result, the structure DB 3 can store the shape of the structure and the deformation detected by the structure in association with the absolute coordinate system based on the position data, here the GPS coordinate system. The shape and deformation measured by the measurement unit 1 can be specified by local coordinates, but by associating with the GPS coordinate system, the shape and deformation measured by the measurement unit 1 can be specified by global coordinates. It becomes. That is, with respect to shapes and deformations, the local coordinates at the time of measurement can be replaced with global coordinates, and all shapes and deformations can have global coordinates. Note that the measuring unit 1 may be able to measure shapes and deformations having global coordinates.

  Next, the deformation status identification unit 43 of the inspection result calculation unit 4 identifies the deformation from the deformation data stored in the initial data storage unit 31 and the additional data storage unit 32 of the structure DB 3 (step S5). The deformation status identification unit 43 identifies, for example, a crack whose length detected by the structure is longer than a specified level as a deformed shape, and processes the deformation status data regarding the identified deformation as processing result data. The data is stored in the storage unit 33. The deformation status identification unit 43 may mark the deformed portion so that the data of the deformed status and the identified deformed portion can be easily distinguished from other shapes and deformations.

  Next, the maintenance management operation unit 5 performs maintenance of the structure using the data stored in the structure DB 3 (step S6). Specifically, the soundness diagnosis unit 51 performs soundness diagnosis using the 3D deformation data in the processing result data storage unit 33. The soundness level diagnosis unit 51 stores the soundness level diagnosis result in the processing result data storage unit 33 of the structure DB 3. Further, the deterioration prediction unit 52 estimates the deterioration tendency from the 3D deformation data and the deformation state of the processing result data storage unit 33, and the deformation data of the initial data storage unit 31 and the additional data storage unit 32, and determines which structure is present. How it will deteriorate. The deterioration predicting unit 52 causes the processing result data storage unit 33 to store a deterioration curve including deterioration transition and deterioration prediction from the past to the present. In addition, the asset management unit 53 repairs using the data of the soundness diagnosis result in the soundness diagnosis unit 51, the deterioration curve based on the deterioration prediction in the deterioration prediction unit 52, and the traffic volume and the surrounding population.

  And the display control part 6 displays the shape and deformation | transformation of a structure in 3D using the data memorize | stored in structure DB3, and the result of the maintenance management process in the maintenance management calculating part 5 (step S7). . Since the position and the deformation of the structure can be specified on the map from the position data, the display control unit 6 can display the information in an easy-to-understand manner for the administrator by displaying it on the map. . Furthermore, traffic information may be superimposed with map information. Further, the traffic volume and the information on the deformation state may be displayed in an overlapping manner.

There is a track B on the map A, and a measurement point group C, a viaduct D, and a station E are shown on the track B. The measurement point group C is, for example, a point cloud that is a measurement result of a laser scanner and displayed on a map, and the building limit measurement result by 3D display on the determination symbol “!” Portion of the measurement point group C on the upper right. F is displayed. The building limit measurement result F is, for example, drawn by changing the color of the point cloud according to the distance from the building limit. In addition, for the determination symbol “!” Of the viaduct D, the measurement values at three locations are displayed from the data obtained by measuring the state of the elevated section G in the lower right, specifically the height from the road to the viaduct. Yes. In addition, regarding the determination symbol “!” Portion of the station E, the state of the home section H, specifically, whether the platform is horizontal is displayed. The display control unit 6 can display the detailed measurement result by referring to the structure DB 3 for the determination symbol selected by the administrator for the display content.

  In the structure maintenance management system 100, the display control unit 6 performs the above display, thereby prompting the administrator to review and repair the measurement of the structure. When the administrator reviews the measurement item, the structure maintenance management system 100 performs the processing from step S1 again based on the revised measurement item. The administrator repeats the structure maintenance management process and review during operation.

  In addition, in the structure maintenance management system 100, when specifying a deformation | transformation, it is also possible to specify using a coordinate. Since the 3D deformation data is related to the absolute coordinate system by the position data, for example, the deformation crack starts from north latitude aa, east longitude bb, altitude cc to north latitude dd, east longitude ee, elevation ff It can also be expressed as continuing.

  As described above, according to the present embodiment, the position of the structure in the absolute coordinate system, the shape of the structure, and the deformation in the structure are measured by the measurement unit 1, and the inspection result calculation unit 4 Using the 3D information of the shape included in the shape data measured by the shape development unit 41, 3D shape data representing the shape in 3D is generated, and included in the deformation data measured by the deformation development unit 42 3D deformation data representing the deformation in 3D is generated using the 3D deformation information to be generated, and the 3D shape data and the 3D deformation data are stored in the structure DB 3 in association with the position information. . Thereby, in the structure maintenance management system 100, a deformation | transformation can be specified by an absolute coordinate system, and the correlation between a structure and a surrounding environment or a surrounding structure can be grasped | ascertained by 3D.

  In addition, the correlation between the current structure and the surrounding environment can be grasped in 3D, and the following is possible. In other words, even if the structure is healthy, it is possible to grasp and predict the danger that occurs due to the building limit due to the surrounding environment, interference with trees, and the like. In addition, the positional relationship between structures such as road and viaduct interference can be grasped in 3D, and the risk can be grasped and predicted from the positional relationship. In addition, it is possible to understand natural terrain changes such as the effect of mountain deformation on tunnels, understand the effects of disasters on structures, and predict damage. By predicting the collapse status of buildings and the damage status when buildings are collapsed, it is possible to prioritize recovery after damage. In addition, it is possible to associate a structure with an original standard, for example, about a kilometer in a railway.

Embodiment 2. FIG.
In the present embodiment, a specific display example in the display control unit 6 of the structure maintenance management system 100 will be described.

The display control unit 6 can display the inspection result based on the result of measuring the structure with reference to the 3D shape, 3D deformation, and deformation state of the processing result data storage unit 33. FIG. 5 is a diagram illustrating an example of a tunnel for displaying the inspection result. FIG. 5A shows the state of occurrence of deformation in 3D display, and FIG. 5B shows the results in each region. Since tunnels are generally divided into areas at specified distances, inspection results are displayed for each area. Here, in region A, there are ² m cracks and 20 cm ² cracks, indicating that there is no peeling and water leakage. Moreover, in the area | region B, there is no crack, a crack, and peeling, and it shows that there are two leaks of 10 cm < ² >. Cracks, creases, and the like are detected by the deformation status identification unit 43, and the detection results are written in the inspection result list and stored in the processing result data storage unit 33 as data of the deformation status. The display control unit 6 can refer to the inspection result list and display the items shown in FIG. 5B with emphasis in FIG. 5A.

  FIG. 6 is a diagram showing the state of strain in the display of the inspection result, and the expression of strain by the contour diagram is represented by contour lines. Further, since the deformation is converted to 3D by the deformation development unit 42, a display that can be viewed from an arbitrary angle is performed. When the deformation status identification unit 43 detects strain and stores the deformation status in the processing result data storage unit 33, each strain shown in (1), (2), and (3) of FIG. Then, the inspection result list including information on the position of the vertex, the size of the mountain, and the height of the mountain is also stored. Here, the position of the peak of the mountain is the position of the point with the largest strain, the size of the mountain is the size of the area surrounded by the outermost contour line, and the height of the mountain is the strain at the peak of the mountain. Indicates the size. By storing a list of inspection results from the past in the processing result data storage unit 33, the display control unit 6 displays the transition of the position of the apex, the size of the mountain, and the height of the mountain due to secular change. Is also possible.

  FIG. 7 is a diagram showing a state of tunnel distortion with respect to display of inspection results. The display control unit 6 superimposes past inspection results and displays a cross section of the overlapped portion. FIG. 7A shows a state in which the strain data from the past is superimposed on the shape of the tunnel, and FIG. 7B shows a state from the cross section AA shown in FIG. 7A. is there. The processing result data storage unit 33 of the structure DB 3 stores 3D deformation data from the past. The display control unit 6 extracts 3D deformation data from the past for the same structure from the processing result data storage unit 33, so that the deformation of the structure measured at different times from the past, in this case, the strain aged. You can display changes.

  FIG. 8 is a diagram showing repair locations for the display of inspection results. Since the structure maintenance management system 100 can input a repair history from the input unit 2, the structure maintenance management system 100 associates the repair history with a deformed position at the time of input. Thereby, in the display control part 6, a repair log | history can be displayed with 3D shape of a structure. For example, when the crack repair of (1) in FIG. 8 is performed in 2008, the peeling repair of (2) is performed in 2009, and the crack repair of (3) is performed in 2010, it is in a close position (1) and (3 ) The manager can be alerted about the repair points. Note that the repair history is not limited to being input from the input unit 2, but can be automatically specified at the time of measurement by performing a process capable of identifying the repair location. In addition, the repair locations (1) and (3) that are close to each other may be automatically associated with each other at the time of input from the input unit 2 or at the time of measurement.

  FIG. 9 is a diagram showing a group of cracks for displaying the inspection result. For example, when a plurality of cracks are generated in a specific range of the structure, the display control unit 6 groups and extracts a group of cracks and displays them. The extraction method may be, for example, a case where the number of cracks of a specified size or more is a specified number or more, but is not limited thereto. In addition, as described above, the processing result data storage unit 33 stores data from the past, so that the display control unit 6 can display the transition of the aggregate of cracks. Although not shown in FIG. 9, for example, a number is assigned to each crack, and the display control unit 6 detects cracks 1 to 5 in 2008 and cracks 6 to 10 in 2009. It may be possible to display that the detection can be identified.

  FIG. 10 is a diagram showing a roadside for the display of the inspection result. The display control unit 6 refers to the 3D shape, the 3D deformation, and the deformation state of the processing result data storage unit 33, and displays a rudder having a depth greater than a specified value on the corresponding road on the map. In addition, as described above, the processing result data storage unit 33 stores data from the past so that the display control unit 6 can perform the checks (1) and (2) shown in FIG. The length, width and depth of the rudder may be displayed. In addition, the structure which judges the necessity for repair in the maintenance management calculating part 5 with respect to the detected state of a rudder may be sufficient.

  FIG. 11 is a diagram illustrating the scraping of road surface signs on the display of inspection results. The display control unit 6 refers to the 3D shape and deformation state of the processing result data storage unit 33, and displays the road marking scraping superimposed on the corresponding road. Further, as described above, the processing result data storage unit 33 stores data from the past, so that the display control unit 6 can reduce the size of the road surface marking at the time of each inspection, for example, the vertical × horizontal size. May be displayed. In addition, the structure which judges the necessity for repair in the maintenance management calculating part 5 may be sufficient with respect to the detected state of the road surface marking.

  FIG. 12 is a diagram illustrating a display example based on the overall soundness level regarding the soundness level diagnosis result. For example, when the structure is a road, as described above, there are a plurality of types of deformation such as rubbing of a road surface sign. The soundness level diagnosis unit 51 of the maintenance management calculation unit 5 performs soundness level diagnosis on a plurality of deformation types for each structure, and stores the soundness level diagnosis result in the processing result data storage unit 33. The display control unit 6 refers to the soundness diagnosis result, and when there is a road with a low soundness level on the displayed map, the display control unit 6 performs display based on the soundness level. For example, when the soundness level is evaluated in three stages of high, medium, and low, roads with low soundness are displayed in red, and roads with high soundness are displayed in blue. FIG. 12A shows a case where the soundness level is low, and FIG. 12B shows a case where the soundness level is medium. Note that the number of stages indicating the degree of soundness and the method of displaying the color indicating the degree of soundness are merely examples, and the present invention is not limited thereto.

  FIG. 13 is a diagram illustrating a display example of the soundness diagnosis result according to the state of individual deformation. FIG. 13A shows a tunnel whose deformation is a specified value, for example, OO or more, and FIG. 13B shows a road with a crack having a specified value, for example, XX or more. The display control unit 6 can also perform display by narrowing down to specific deformation items in the soundness diagnosis result.

  FIG. 14 is a diagram showing priorities in the same kind of structure for asset management. When the target structure is a tunnel, the asset management unit 53 determines the priority of the fixed information based on the importance of the traffic volume and the surrounding population, which is expected to have no major fluctuation in the short period of time for the tunnels A and B. Based on the soundness classification based on the result of the soundness diagnosis and the overall evaluation of the soundness of the structure, the priority of the soundness, the total cost for repair, and the repair cost incurred in the case of the most recent repair, further increase the desired amount Refer to and determine the priority for repair. Here, it is assumed that tunnel A has priority 1 and tunnel B has priority 2. The display control unit 6 displays the data used when the asset management unit 53 determines the priority order of repair targets.

  FIG. 15 is a diagram showing the content of a proposal for a repair method for asset management. The asset management unit 53 can propose a plurality of repair methods when repairing a structure. For example, when the administrator selects the tunnel B from the contents displayed on the display control unit 6, the asset management unit 53 proposes two repair methods, plan A and plan B, to the tunnel B, and the display control unit 6 displays two repair methods for the tunnel B proposed by the asset management unit 53. Plan A is a repair plan that uses repair materials and does not peel off the pavement and reinforces the steel frame. Plan B is a repair plan that uses repair materials and does not peel off the pavement and does not reinforce the steel frame. is there. The manager selects a repair plan from the proposed repair method in consideration of the desired amount.

  FIG. 16 is a diagram showing a method for identifying a structure when kilometer is used. In a railway, the distance of about a kilometer differs from the actual distance actually measured by Doppler radar. The actual distance of about a kilometer always changes due to changes in track temperature and ballast replacement work. The position of the target is expressed by the relative distance from the kilometer in the railway industry. It is easy to understand if the kilometer and the target are displayed on the map from GPS data. Because it is possible to specify the position of the kilometer in relation to the GPS coordinates, the position of the target objects (a) and (b), which are structures, is represented by the relative distance from the kilometer distance, so that the GPS coordinates The approximate position can be specified.

  In addition, about the structure of the structure maintenance management system 100 shown in FIG. 1, between each structure is not limited to a wired connection, You may make it a wireless connection. For example, the function of the display control unit 6 is given to a tablet terminal that can be used outdoors. FIG. 17 is a diagram illustrating a state in which the worker confirms the deformed state. The worker confirms the state of deformation displayed on the tablet terminal, which is the display control unit 6, before the deformation of the target structure, so that the worker can reliably perform measurement or repair work using the tool. It is possible to grasp the target deformation.

  As described above, according to the present embodiment, the display control unit 6 uses the absolute coordinate system based on the position information, 3D shape data, and 3D deformation data stored in the structure DB 3. The structure can be displayed along with the deformation. Moreover, in the display control part 6, a structure can be superimposed and displayed on map information using the map information memorize | stored in structure DB3. In addition, the display control unit 6 displays the structures measured at different times by using the 3D shape data and the 3D deformation data for a plurality of times measured in the past stored in the structure DB 3. Can do. Further, the deformed portion can be displayed on the structure by using the deformed state data detected by the deformed state identifying unit 43 and stored in the structure DB 3. At this time, the data on the state of change from the past may be displayed in a superimposed manner so that the state of the change can be understood in time series.

  Further, since the shape and deformation of the structure can be stored as 3D data, the following becomes possible. That is, it is possible to superimpose structure deformation and deterioration information that require 3D information. For example, it is possible to superimpose the surface shape such as cracks on the distortion of the pavement surface and the protruding surface of the slope. In addition, since various deformations can be overlapped in 3D, there is a possibility that a deterioration process that cannot be understood in 2D can be understood. In addition, since time information is given to the 3D data of shape and deformation, the progress of deterioration can be seen. Also, internal deformations such as cavities and steel frames can be measured. In addition, it is possible to grasp deformations that cannot be recognized in 2D, for example, the depth of cracks, the removal of anchors, the amount of water leakage, and the distinction between dirt and cracks. In addition, when the structure is updated, 3D shape and deformation data can be directly reflected in the 3D design data. Moreover, when superimposing information, you may superimpose the information of a traffic volume and a deformation condition.

Embodiment 3 FIG.
In the present embodiment, the difference between the maintenance and management of the structure in 2D that has been performed conventionally and the maintenance and management of the structure in 3D in the structure maintenance and management system 100 described in the first and second embodiments. explain. 18 to 21, the first column from the left indicates a process type. In each figure, 2D and 3D show the effects of what means are used for each process and what can be achieved by using those means. ing.

  FIG. 18 is a diagram showing a difference in inspection for maintenance management by 2D and 3D. Here, the inspection is an operation until measurement is performed by the measurement unit 1 and before 3D shape data and 3D deformation data are stored in the structure DB 3 in the first embodiment. Regarding shape measurement, in 2D, the road surface state such as a white line can be measured by a camera, but in 3D, a 3D shape of a structure and its surroundings can be measured by a laser scanner and modeling. As for deformation measurement, in 2D, a step can be measured by a vibration sensor, vehicle running sound, and visual observation, but in 3D, the relationship between deformations can be measured by various sensors. In addition, superimposition of deformation on the measurement shape is impossible in 2D, but in 3D, 3D superimposition of various deformations can be performed by superimposing the 3D deformation on the 3D shape. As for the position of the measurement point such as the position of the camera and the position of the measurer, 2D can display 2D coordinates by GPS, but 3D can display 3D coordinates by GPS, IMU, and odometer. In addition, although 3D coordinate display of shape and deformation is not possible with 2D, 3D coordinate display can be performed with GPS, IMU, odometer, and laser scanner in 3D.

  FIG. 19 is a diagram illustrating a difference in storage and display of data in a database for 2D and 3D maintenance management. With regard to the superimposition of other structures, in 2D, 3D CAD data can be converted into 2D, and the structure in 2D can be superposed, and in 3D, the structure can be obtained by superimposing the measured 3D data and 3D data of other structures Correlation between objects can be made into 3D. In addition, regarding the setting of the virtual viewpoint, in 2D, it is possible to display from the measurer's viewpoint based on the GPS value of the measurer or the measuring means. Since the 3D coordinates are known, the viewpoint can be set freely. As for 2D display, only the surface measured by displaying 2D data can be displayed in 2D, but in 3D, it can be freely sliced and displayed in XYZ by the viewpoint conversion and integration of 3D data. Further, although 3D display of deformation is impossible in 2D, 3D display of deformation can be performed by expanding the deformation data into a three-dimensional shape generated from a laser scanner. In addition, in 2D, a matched image can be extracted by partial image matching in 2D, but in 3D, a matched 3D structure can be extracted by 3D point cloud matching, and 2D can also be extracted.

  FIG. 20 is a diagram illustrating a difference in soundness diagnosis regarding maintenance management by 2D and 3D. With regard to the secular change survey, in 2D, the secular change can be investigated by positioning on a projected image to 2D, but in 3D, the secular change can be surveyed with high accuracy by positioning in 3D coordinates. As for the detection of deformation size, in 2D, the size of the result of projecting a three-dimensional structure onto a two-dimensional plane can be detected by superimposing camera images. In 3D, measurement data such as a deformation image can be detected in 3D shape. The size of the deformation of the object can be detected regardless of the camera direction. As for the health diagnosis, in 2D, it is possible to diagnose the soundness of the structure alone by diagnosis from the deformation of each structure, but in 3D, the correlation between the structure alone or other structures or natural topography is examined. By doing so, the soundness diagnosis including the influence of the structure alone or the surroundings can be performed.

  FIG. 21 is a diagram illustrating a difference between a management plan and maintenance management for 2D and 3D maintenance management. Reflecting the inspection result on the 3D drawing is impossible in 2D, but in 3D, the inspection result can be superimposed on the 3D drawing to create a 3D drawing.

  As described above, the structure maintenance management system 100 has many effects as compared with the conventional 2D structure maintenance management.

  Here, a hardware configuration for realizing each configuration of the block diagram of the structure maintenance management system 100 shown in FIG. 1 will be described. FIG. 22 is a diagram illustrating a hardware configuration example of the structure maintenance management system 100 according to the first to third embodiments.
