JP7814289B2 - Repair planning support system, repair planning support device, repair planning support method, and repair planning support program - Google Patents

Description

This disclosure relates to a repair planning support system, repair planning support device, repair planning support method, and repair planning support program that support the creation of repair plans for infrastructure structures such as railway and road bridges and tunnels.

Railway and road infrastructure such as bridges and tunnels, as well as buildings and other facilities, require regular inspections and management, such as repair work, if any damage or other problems are discovered. Generally, the upper limit of the repair costs that can be used for repair work is set in advance, such as an annual budget, so repair work must be carried out efficiently within the budget.

In response to this problem, for example, Patent Document 1 describes a repair plan development device that detects damage to tangible objects, such as roads and surrounding structures, based on point cloud data acquired as measurement results, determines priorities according to the degree of the detected damage, and develops repair plans for the tangible objects based on the determined priorities and budget.

Japanese Patent Application Laid-Open No. 2021-184202

The technology described in Patent Document 1 calculates the size of a tangible object from the point cloud data of each individual object, and calculates repair costs by multiplying the calculated size by the repair cost entered by the administrator. However, in reality, there is damage to the tangible object that can be repaired only partially rather than repairing the entire object, and depending on the location of the damage, additional measures such as installing scaffolding may be required. As a result, there is a problem in that accurate repair costs cannot be reflected in plans unless various conditions for each tangible object are taken into consideration.

This disclosure has been made in light of the above, and aims to provide a repair planning support system that can improve the accuracy of repair cost calculations.

To solve the above-mentioned problems and achieve the objectives, the repair planning support system disclosed herein comprises a 3D point cloud display unit that displays a 3D point cloud of the object to be repaired; a range selection unit that accepts the selection of any range of the 3D point cloud; a selection operation unit that accepts the selection of a construction method for repair work to be carried out for the selected range, which is the range accepted by the range selection unit; a polygon input unit that accepts input of a polygon indicating the installation area of scaffolding to be used in the repair work on the object to be repaired; and a cost calculation unit that calculates the cost of repair work to be carried out for the selected range based on the size of the selected range, the selected construction method, which is the construction method accepted by the selection operation unit, and the size of the polygon accepted as input by the polygon input unit.

This disclosure has the effect of providing a repair planning support system that can improve the accuracy of repair cost calculations.

The following describes in detail the repair plan support system, repair plan support device, repair plan support method, and repair plan support program according to embodiments of the present disclosure, with reference to the accompanying drawings.

Embodiment 1.
1 is a diagram showing an example of the configuration of a repair plan support system 100 according to a first embodiment. The repair plan support system 100 includes a server 1 that operates as a repair plan support device that supports the creation of a repair plan, and a client 2 that acquires information necessary for creating a repair plan from a user and transfers it to the server 1, and notifies the user of the repair plan created by the server 1. Note that the server 1 and the client 2 are connected via a network, but the network is not shown in FIG. 1.

The repair plan support system 100 supports the creation of repair plans for infrastructure structures such as railway and road bridges and tunnels. The repair plan support system 100 may also support the creation of repair plans for facilities such as buildings instead of infrastructure structure repair plans. In the following explanation, the infrastructure structures, facilities, etc. for which the repair plan support system 100 supports the creation of repair plans will be collectively referred to as "repair objects."

The server 1 includes a memory unit 11 that stores various information necessary for creating a repair plan, and an information processing unit 12 that supports the creation of a repair plan for the object to be repaired based on the information stored in the memory unit 11 and information acquired by the client 2 from the user.

The memory unit 11 includes a point cloud information database (DB) 111, a deformation information database (DB) 112, a deformation/construction method related information database (DB) 113, a repair construction method information database (DB) 114, a scaffolding information database (DB) 115, and a construction information database (DB) 116.

The point cloud information database 111 stores three-dimensional point cloud data obtained by measuring the object to be repaired with a three-dimensional measuring device when inspecting the object to be repaired. In other words, the point cloud information database 111 stores three-dimensional point cloud data of the object to be repaired.

The deformation information database 112 stores information related to deformations detected in the object to be repaired as deformation information. An example of deformation information is shown in Figure 2. Figure 2 is a diagram showing an example of deformation information stored in the deformation information database 112. As shown in Figure 2, the deformation information includes a deformation ID (identifier), a deformation type, the degree of deformation, i.e., a judgment category indicating the level of damage, and position coordinates indicating the position of the deformation. The deformation information is created by analyzing the three-dimensional point cloud data of the object to be repaired. The process of analyzing the three-dimensional point cloud data and creating the deformation information may be performed by the information processing unit 12, or may be performed by a device external to the repair plan support system 100. Deformation information is created and updated, for example, when new three-dimensional point cloud data is registered in the point cloud information database 111 or when three-dimensional point cloud data already registered in the point cloud information database 111 is updated.

The deformation/construction method related information database 113 stores information indicating the relationship between the deformation type and degree of deformation and the construction methods that can be used to repair the deformation as deformation/construction method related information. An example of deformation/construction method related information is shown in Figure 3. Figure 3 is a diagram showing an example of deformation/construction method related information stored in the deformation/construction method related information database 113. The deformation/construction method related information includes a construction type indicating the type of work, a deformation type, the above-mentioned judgment category, and a selectable construction method ID indicating the construction methods that can be selected for the combination of the construction type, deformation type, and judgment category. The deformation/construction method related information is created in advance by a user who manages the object to be repaired, and is registered in the deformation/construction method related information database 113.

The repair method information database 114 stores information related to repair methods as repair method information. An example of repair method information is shown in Figure 4. Figure 4 is a diagram showing an example of repair method information stored in the repair method information database 114. The repair method information includes a method ID, a method indicating the construction method, a repair unit price indicating the unit cost when repair is performed using the method listed in the same row, and scaffolding installation conditions indicating whether the method listed in the same row satisfies the scaffolding installation conditions. The repair method information is created in advance by a user or other person who manages the object to be repaired, and is registered in the repair method information database 114.

The scaffolding information database 115 stores information related to scaffolding as scaffolding information. An example of scaffolding information is shown in Figure 5. Figure 5 is a diagram showing an example of scaffolding information stored in the scaffolding information database 115. The scaffolding information includes a scaffolding ID, the type of work described above, a scaffolding type, installation conditions indicating the conditions under which the scaffolding can be installed, a unit for calculating the scaffolding installation cost, and a unit price indicating the cost per unit listed in the same row. The scaffolding information is created in advance by a user or other person who manages the object to be repaired, and is registered in the scaffolding information database 115.

The construction information database 116 stores information about repair work carried out in the past to repair deformations as construction information. An example of construction information is shown in Figure 6. Figure 6 is a diagram showing an example of construction information stored in the construction information database 116. The construction information includes a construction ID, contractor, construction name, the type of work described above, scaffolding type, cost required for the construction, and construction period. Construction information is created by a user or other person who manages the object to be repaired each time repair work is carried out, and is registered in the construction information database 116.

The information processing unit 12 includes a deformation information acquisition unit 13, a repair method extraction unit 14, a cost calculation unit 15 consisting of a basic cost calculation unit 16 and an incidental cost calculation unit 17, and a construction period calculation unit 18.

The deformation information acquisition unit 13 acquires deformation information corresponding to each deformation existing within the range selected by the user from the deformation information database 112.

The repair method extraction unit 14 extracts information about repair methods that meet the conditions specified by the user from the repair method information database 114.

The cost calculation unit 15 calculates the cost required for repair work to be carried out under conditions specified by the user.

The basic cost calculation unit 16 of the cost calculation unit 15 calculates the basic cost of construction work that will be incurred when repairing the deformation using the repair method specified by the user.

The incidental cost calculation unit 17 of the cost calculation unit 15 calculates the incidental costs of the construction work that will be incurred when repairing the deformation using the repair method specified by the user.

The construction period calculation unit 18 calculates the construction period required to repair each defect within the range selected by the user using the repair method and conditions specified by the user.

Client 2 includes an operation reception unit 21 that receives operations from the user to create a repair plan, and a display unit 25 that displays a menu screen that receives operations to create a repair plan, a display screen for the results of the repair plan creation, etc.

The operation reception unit 21 includes a range selection unit 22, a selection operation unit 23, and a polygon input unit 24.

The range selection unit 22 accepts operations to select the range of deformations in the repair target object to be repaired. The selection operation unit 23 accepts operations such as selecting one or more options from multiple options during the process of creating a repair plan, and menu selection operations. The polygon input unit 24 accepts operations to input polygons indicating the area where scaffolding will be installed when scaffolding is required for repair work.

The display unit 25 includes a three-dimensional point cloud display unit 26 and an information display unit 27.

The three-dimensional point cloud display unit 26 displays a three-dimensional point cloud of the object to be repaired on the screen. The three-dimensional point cloud data of the object to be repaired is registered in the point cloud information database 111 provided in the memory unit 11 of the server 1. The three-dimensional point cloud display unit 26 acquires the three-dimensional point cloud data of the object to be repaired for displaying the three-dimensional point cloud from the point cloud information database 111. The information display unit 27 displays various information other than the three-dimensional point cloud, expressed by letters, numbers, symbols, etc., on the screen. The information display unit 27 acquires each piece of information to be displayed on the screen from the memory unit 11 and information processing unit 12 of the server 1.

Next, the operation of the server 1 in the repair plan support system 100 according to the first embodiment to create a repair plan will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an example of the operation of the server 1 operating as the repair plan support device according to the first embodiment to create a repair plan. In the repair plan support system 100, the server 1 starts the operation according to the flowchart shown in FIG. 7 when the user selects the range for repairing the deformation in the object to be repaired. That is, when the range selection unit 22 of the client 2 accepts the selection of the range for repairing the deformation from the user, the server 1 starts the operation according to the flowchart shown in FIG. 7.

When the user selects the area to repair the deformation, the deformation information acquisition unit 13 acquires the position coordinate information and area value of the area selected by the user (step S1). Specifically, the area selection unit 22 of the client 2 transmits the position coordinate information and area value of the area selected by the user to the server 1, and the deformation information acquisition unit 13 acquires this information.

Next, the deformation information acquisition unit 13 creates a list of deformations included in the range indicated by the acquired location coordinate information, i.e., deformations that exist within the range selected by the user (step S2). Specifically, the deformation information acquisition unit 13 acquires deformation information (see Figure 2) whose location coordinates fall within the range selected by the user from the deformation information database 112, and creates a list of the acquired deformation information. The list of deformation information is notified to the user via client 2, as will be explained in detail later. The user checks the list of deformation information and selects one or more deformations to repair.

Next, the repair method extraction unit 14 extracts candidate repair methods based on the information on the deformation selected by the user (step S3). A deformation selected by the user is a deformation that the user has determined to require repair. In the following explanation, a deformation selected by the user may be referred to as a "deformation to be repaired." In step S3, the repair method extraction unit 14 checks the deformation/deformation method related information database 113, identifies methods that can repair all deformations to be repaired, and sets the identified methods as candidate repair methods. There may be multiple candidate repair methods.

Next, the basic cost calculation unit 16 calculates the basic cost of performing repairs using each repair method candidate extracted by the repair method extraction unit 14 and determines whether scaffolding is required, and creates a list of candidate repair method information (step S4). In step S4, the basic cost calculation unit 16 checks the repair method information database 114 and calculates the basic cost by multiplying the area value acquired in step S1 by the repair unit price included in the repair method information corresponding to each candidate repair method (see Figure 4). The basic cost calculation unit 16 also determines whether scaffolding is required based on the location of the deformation to be repaired and the repair method information. The basic cost calculation unit 16 associates the calculated basic cost, information on whether scaffolding is required, and information on candidate repair methods to create a list of candidate repair method information. The list of candidate repair method information is notified to the user via client 2, as will be described in detail later. The user checks the list of candidate repair methods and selects the method to be used for the repair.

Next, it is confirmed whether scaffolding is required for the repair method selected by the user (step S5). If scaffolding is required (step S5: Yes), the incidental cost calculation unit 17 creates a list of scaffolding candidates based on the polygons input by the user (step S6). In step S6, if the scaffolding installation necessity information associated with the repair method selected by the user indicates that scaffolding installation is required, the incidental cost calculation unit 17 accepts input from the user of a polygon representing the scaffolding installation area. In addition, the incidental cost calculation unit 17 checks the scaffolding information held in the scaffolding information database 115 and identifies scaffolding that can be installed in the area represented by the polygons input by the user, and sets this as scaffolding candidates. The incidental cost calculation unit 17 creates a list of the candidate scaffoldings, which serves as a scaffolding candidate list. The scaffolding candidate list is notified to the user via client 2, as will be described in detail later. The user checks the list of scaffolding candidates and selects the scaffolding to install.

Next, the incidental cost calculation unit 17 calculates the incidental costs when using the scaffolding selected by the user (step S7). The incidental cost calculation unit 17 calculates the incidental costs using the unit price included in the scaffolding information corresponding to the selected scaffolding (see Figure 5).

Next, the construction period calculation unit 18 calculates the construction period when repairs are performed using the repair method specified by the user (step S8). The construction period calculation unit 18 calculates the construction period based on the construction information held in the construction information database 116. Details of the construction period calculation method will be explained separately.

Furthermore, if the repair method selected by the user from the above repair method candidates does not require scaffolding (step S5: No), steps S6 and S7 above are omitted and step S8 is executed.

Next, the operation of the repair plan support system 100 according to the first embodiment will be explained in detail using a specific example.

Figure 8 is a flowchart showing an example of the operation of the repair plan support system 100 according to the first embodiment. In the repair plan support system 100, the server 1 and client 2 operate according to the flowchart in Figure 8 to create a repair plan for an object to be repaired.

As shown in FIG. 8, in the repair planning support system 100, the client 2 first displays a point cloud screen (step S101). Specifically, the 3D point cloud display unit 26 of the display unit 25 displays a 3D point cloud of the repair object on the screen. The repair object for which the 3D point cloud is to be displayed on the screen is selected by the user, but any operation may be performed before the selection of the repair object is received from the user.

The client 2 then accepts a point cloud selection on the point cloud screen (step S102). Specifically, the range selection unit 22 of the operation acceptance unit 21 accepts from the user a selection of an arbitrary range of the 3D point cloud of the object to be repaired displayed on the screen.

The client 2 then acquires the coordinate position and actual area value of the point cloud selected by the user (step S103). Specifically, the range selection unit 22 of the operation reception unit 21 acquires coordinates indicating the range selected by the user in step S102 and sets these as the coordinate position, and also calculates the area of the range selected by the user and sets this as the actual area value. The coordinate position may include coordinates that indicate the range selected by the user, and may be, for example, the coordinates of each of the three-dimensional point clouds that form the perimeter of the range. Furthermore, if the selected range is rectangular, the coordinate position is determined to be the coordinates of the four three-dimensional point clouds corresponding to the four corners. The range selection unit 22 then transmits the acquired coordinate position and actual area value to the server 1.

When the server 1 receives the coordinate positions and actual area values of the point cloud selected by the user from the client 2, it acquires the deformation type, judgment category, and location coordinates of the deformations included in the selected range (step S201). The selected range here is the range indicated by the coordinate positions received from the client 2, i.e., the range selected by the user in step S102. In step S201, the deformation information acquisition unit 13 of the information processing unit 12 acquires the deformation type, judgment category, and location coordinates of each deformation included in the selected range from the deformation information database 112. In other words, the deformation information acquisition unit 13 acquires the deformation type, judgment category, and location coordinates from the deformation information (see Figure 2) corresponding to each deformation included in the selected range.

The deformation information acquisition unit 13 creates a deformation information list using the acquired deformation type, assessment category, and location coordinates, and sends it to the client 2. The deformation information list includes the acquired deformation type, assessment category, and location coordinates. The client 2 displays the received deformation information list (step S104). Specifically, the information display unit 27 of the display unit 25 displays the deformation information list received from the server 1. Figure 9 is a diagram showing an example of a screen display including a display of the deformation information list. For example, as shown in Figure 9, the information display unit 27 displays the deformation information list 312 on the right side of the center of the screen 300. Note that the display position of the deformation information list 312 may be anywhere on the screen 300. The point cloud display area 310 displays a three-dimensional point cloud 3101 of the object to be repaired. A rectangle 3102 in the point cloud display area 310 represents the range selected by the user in step S102 above. The range indicated by the rectangle 3102 is the range to be repaired. Screen 300 also includes a display 311 showing the upper left coordinate, lower right coordinate, and size of the range indicated by rectangle 3102, i.e., the range selected by the user. The "size" here refers to the area of the range indicated by rectangle 3102, and corresponds to the actual area value acquired in step S103 described above. Note that processing related to the display of the 3D point cloud in point cloud display area 310 is performed by 3D point cloud display unit 26, and processing related to the display of text and the like in areas other than point cloud display area 310 is performed by information display unit 27.

Next, the client 2 accepts the selection of the deformation to be repaired from the user (step S105). Specifically, the selection operation unit 23 of the operation acceptance unit 21 accepts the selection of the deformation to be repaired from the deformation information list 312 on the screen 300 shown in FIG. 9. In the example shown in FIG. 9, the user selects the deformation to be repaired by checking the checkbox for the item marked "Select." The deformation selected by the user in step S105 becomes the deformation to be repaired. The client 2 transmits the selection results of the deformation to be repaired to the server 1.

When the server 1 receives the selection results of the deformations to be repaired, it identifies a construction method that can be used to repair the deformations to be repaired (step S202). Specifically, the repair method extraction unit 14 identifies a construction method that can be used to repair the deformations to be repaired based on the deformation information of the deformations to be repaired and the deformation/construction method related information held in the deformation/construction method related information database 113. That is, the repair method extraction unit 14 identifies deformation/construction method related information that matches the type of work, deformation type, and judgment classification included in the deformation information of the deformation to be repaired, and determines the construction method corresponding to the selectable construction method ID included in the identified deformation/construction method related information as a construction method that can be used to repair the deformations to be repaired. If there are multiple deformations to be repaired, the repair method extraction unit 14 identifies a construction method that can be used to repair each deformation to be repaired.

The server 1 then checks whether there is a construction method that can address all of the deformations (step S203). Specifically, the repair method extraction unit 14 checks whether there is a construction method that can repair all of the deformations that are subject to repair among the construction methods identified in step S202.

If there is no construction method that can address all of the deformations (step S203: No), the server 1 notifies the client 2 that there is no construction method that can be used, and the client 2 requests the user to reselect the deformations (step S106) and accepts the selection of the deformations to be repaired from the user (step S105).

If a construction method that can handle all deformations exists (Step S203: Yes), the server 1 checks whether the scaffolding installation conditions are applicable (Step S204). Specifically, the repair method extraction unit 14 checks whether the scaffolding installation conditions in the repair method information (see Figure 4) for a construction method that can handle all deformations are "applicable" or "inapplicable."

If the scaffolding installation conditions are met (Step S204: Yes), the server 1 determines whether scaffolding is required for each of the construction methods that can address all deformations, i.e., whether scaffolding is actually required (Step S205). Specifically, the repair method extraction unit 14 determines whether scaffolding is required based on the type of construction method that can address all deformations and the coordinate information of the selected range, which is the range selected by the user in Step S102 above. For example, when the type of construction is tunnel repair work, the repair method extraction unit 14 determines that scaffolding is required if the height of the selected range is equal to or greater than a specified threshold, and determines that scaffolding is not required if the height is less than the threshold. In other words, the repair method extraction unit 14 determines that scaffolding is required if the selected range, which is the range where repair work will be performed, is at a height that makes work impossible without scaffolding. Furthermore, when the type of construction is deck slab reinforcement work, the repair method extraction unit 14 determines that scaffolding is required regardless of the height of the selected range.

If the scaffolding installation conditions are not met (step S204: No) and if the processing of step S205 is completed, the server 1 transmits information regarding construction methods that can address all the deformations to the client 2. The client 2 creates a list of construction methods that can address all the deformations based on the information received from the server 1 and displays the created list on the screen as a list of candidate repair methods (step S107). Specifically, the information display unit 27 of the display unit 25 creates a list of candidate repair methods, which is a list of construction methods that can address all the deformations, and displays it on the screen. The information display unit 27 displays the list of candidate repair methods by adding it to the screen 300 shown in FIG. 9 . For example, the display content may be as shown in FIG. 10 . FIG. 10 is a diagram illustrating an example of a screen display including a list of candidate repair methods. In FIG. 10 , the same reference numerals are used for the same components as in the other drawings. For example, the information display unit 27 displays a candidate repair method list 313 on the lower right side of the screen 300, as shown in FIG. 10 . The repair method candidate list 313 includes information on "method,""repair unit price,""basiccost," and "scaffolding installation." The "basic cost" is calculated by multiplying the actual area value acquired in step S103 by the "repair unit price." In the example of FIG. 10 , the actual area value (size of the selected area) = 10 ^m2 . Note that while it is assumed that the calculation of the basic cost is performed by the basic cost calculation unit 16 of the server 1, it may also be performed by the information display unit 27. The information display unit 27 also displays a button 314 for starting a cost simulation for repairs performed using the repair method selected by the user. The repair method extraction unit 14 may also create a list of methods that can address all deformations and transmit the created list of methods to the client 2.

Next, client 2 accepts from the user the selection of the repair method to be implemented (step S108). Specifically, the selection operation unit 23 of the operation reception unit 21 accepts an operation to select one candidate repair method from the list of candidate repair methods 313 displayed on the screen 300 as the method to be used to repair the deformation to be repaired. In the example shown in Figure 10, the user selects the method to be used for the repair by checking the checkbox for the item marked "Select" in the list of candidate repair methods 313. When the selection operation unit 23 detects that the method to be used for the repair has been selected and that button 314 has been pressed, the next process begins.

When the user presses button 314, client 2 accepts polygon input into point cloud display area 310 (step S109). The polygon here represents the area where the scaffolding will be installed. The polygon input is accepted by the polygon input unit 24 of the operation acceptance unit 21. That is, the polygon input unit 24 accepts the specification of the scaffolding installation area by polygon input. There is no restriction on the method for inputting polygons. Polygon input can be performed using any commonly used method.

In the example shown in Figure 10, all of the repair methods listed in the repair method candidate list 313 for "Scaffolding Installation" are "Required," so steps S109 to S113 and step S206 are executed after step S108 to calculate the incidental costs incurred due to the installation of scaffolding. However, if the repair method candidate list 313 includes a repair method for which "Scaffolding Installation = Not Required" and step S108 accepts the selection of a repair method that does not require scaffolding installation, steps S109 to S113 and step S206 are not executed. In other words, step S114 is executed after step S108.

When the polygon input unit 24 accepts polygon input, it checks whether the input polygon interferes with the point cloud (step S110). The point cloud here refers to the point cloud selected in step S102 described above, i.e., the area selected by the user where repair work will be carried out. If the polygon interferes with the point cloud (step S110: Yes), the client 2 requests that the polygon be re-input (step S111) and returns to step S109 to accept polygon input into the point cloud display area 310.

If the polygon does not interfere with the point cloud (step S110: No), the client 2 transmits the input polygon information to the server 1, and the server 1 acquires scaffolding information that satisfies the installation conditions indicated by the polygon (step S206). Specifically, the incidental cost calculation unit 17 of the information processing unit 12 extracts from the scaffolding information database 115 scaffolding information (see Figure 5) that is the same type of work as the repair method selected in step S108 and whose polygon area represented by the received information satisfies the installation conditions.

The incidental cost calculation unit 17 creates a list of scaffolding candidates based on the extracted scaffolding information and transmits it to the client 2. The client 2 displays the received list of scaffolding candidates (step S112) and accepts the selection of the scaffolding to be installed (step S113). Specifically, the information display unit 27 of the display unit 25 displays the list of scaffolding candidates received from the server 1, and the selection operation unit 23 of the operation reception unit 21 accepts the selection of the scaffolding to be installed from the user.

When scaffolding is selected, client 2 displays the cost on the screen and then accepts an operation to transition to the construction period simulation screen (step S114). Specifically, the information display unit 27 displays the cost of the repair work on the screen, and the selection operation unit 23 accepts an operation to transition to the construction period simulation screen. Figure 11 is a diagram showing an example of a screen display including a display of the cost of the repair work. In Figure 11, the same reference numerals are used for the same parts as in other drawings. For example, as shown in Figure 11, the information display unit 27 displays repair work cost details 322 in the center of screen 301. Note that the display position of repair work cost details 322 may be anywhere on screen 301.

In addition to the repair work cost details 322, screen 301 also includes a point cloud display area 310, a scaffolding candidate list 321, construction-related information 323, and a button 324 for transitioning to the construction period simulation screen, but these display start timings vary. Before the polygon is input in step S109 described above, screen 301 displays only the 3D point cloud 3101 of the repair object, a rectangle 3102, and construction-related information 323 in the point cloud display area 310. The rectangular parallelepiped 3103 in the point cloud display area 310 corresponds to the polygon input in step S109 described above, and its display begins when the polygon is input. The 3D point cloud display unit 26, which displays the 3D point cloud in the point cloud display area 310, superimposes the rectangular parallelepiped 3103, which is a polygon, on the rectangle 3102, which is the selected range. The scaffolding candidate list 321 begins displaying in step S112 described above. Button 324 begins displaying at the same time as repair work cost details 322, i.e., in step S114.

The "Basic Cost" included in the repair work cost details 322 corresponds to the "Basic Cost" included in the repair method candidate list 313 on the screen 300 shown in Figure 10. The "Scaffolding Fee" corresponds to the "Cost" included in the scaffolding candidate list 321. Furthermore, the "Cost" corresponds to the "Unit Price" included in the scaffolding information held by the scaffolding information database 115 (see Figure 5).

Note that if client 2 accepts the selection of a repair method that does not require scaffolding in step S108 above and proceeds to step S114 without executing steps S109 to S113 and step S206 above, the scaffolding candidate list 321 and the scaffolding costs in the repair work cost details 322 will not be displayed on screen 301.

Furthermore, if it is determined in step S110 above that a polygon is interfering with the point cloud and re-input of the polygon is requested in step S111, client 2 displays, for example, screen 302 shown in FIG. 12. FIG. 12 is a diagram showing an example of a screen display including a display requesting re-input of polygons required for calculating the cost of repair work. That is, client 2 displays text 325 requesting re-input of polygons instead of the scaffolding candidate list 321 on screen 301 shown in FIG. 11.

When the user presses button 324 on screen 301, the next process begins, and client 2 accepts the selection of a contractor (step S115). Specifically, the information display unit 27 of client 2 displays selectable contractors and accepts the user's selection. Selectable contractors are those who can carry out the repair method selected in step S108 described above, and contractors who can carry out the selected repair method are identified based on the type of work included in the construction information held by the construction information database 116 (see Figure 6). This process may be performed by, for example, the construction period calculation unit 18 of server 1, or by the information display unit 27. Client 2 transmits the contractor selection results to server 1.

Upon receiving the contractor selection results, the server 1 calculates the estimated construction period based on the construction information stored in the construction information database 116 (step S207). Specifically, the construction period calculation unit 18 identifies construction information for construction similar to the construction using the repair method selected in step S108 from the construction information stored in the construction information database 116, and uses the "construction period" included in the identified construction information as the estimated construction period. A similar construction is one for which the "contractor," "type of work," and "scaffolding type" included in the construction information are the same, and whose "cost" is close to the cost displayed in step S114 above, i.e., the total of the basic cost and scaffolding cost in the cost details 322 shown in FIG. 11. For example, the construction period calculation unit 18 determines that a construction is similar if the "contractor," "type of work," and "scaffolding type" included in the construction information are the same, and the difference in "cost" is below a specified threshold. The construction period calculation unit 18 calculates the estimated construction period based on the "construction period" included in the construction information for the similar construction. For example, the construction period calculation unit 18 sets the "construction period" of the construction project with the highest similarity, i.e., the construction project with the smallest difference in cost, as the predicted construction period. The construction period calculation unit 18 may also set the average value of the "construction periods" of multiple similar construction projects as the predicted construction period. Note that if no similar construction projects exist, the server 1 may notify the user via the client 2 that it is not possible to calculate the predicted construction period and terminate the processing.

The server 1 then determines a date that can be inserted based on the estimated construction period (step S208). Specifically, the construction period calculation unit 18 determines the construction schedule based on the possible construction period and estimated construction period previously acquired by the user. The possible construction period is the period during which the user wishes to carry out the construction, such as from month x to month △. If the possible construction period has not yet been acquired, the construction period calculation unit 18 only performs step S207, which calculates the construction period, and does not perform step S208.

The server 1 notifies the client 2 of the determined construction schedule, and the client 2 displays the construction schedule on the display unit 25 (step S116). The construction schedule is displayed by the information display unit 27. Figure 13 is a diagram showing an example of a screen display including a repair work schedule. In Figure 13, the same reference numerals are used for the same parts as in other drawings. For example, as shown in Figure 13, the information display unit 27 displays the repair work construction period 334 and schedule 335 on the right side of the center of the screen 303. Note that the display positions of the repair work construction period 334 and schedule 335 may be anywhere on the screen 303. If the server 1 does not execute step S208, i.e., if the construction schedule is not determined, the information display unit 27 displays only the construction period 334 and does not display the schedule 335.

In addition to the repair work period 334 and schedule 335, screen 303 also includes a point cloud display area 310, a contractor selection menu 331, construction-related information 323, repair work cost 333, and a button 336 for exiting the construction period simulation screen. The display of point cloud display area 310, construction-related information 323, repair work cost 333, and button 336 for exiting the construction period simulation screen are fixed. The repair work period 334 and schedule 335 may be updated each time a contractor is selected in the contractor selection menu 331. In other words, when a contractor is selected in the contractor selection menu 331, server 1 may again execute steps S207 and S208, and client 2 may execute step S116 to update the repair work period 334 and schedule 335 on screen 303. When button 336 is operated, the repair planning support system 100 terminates operation.

Next, we will explain the hardware configuration of the server 1 that operates as a repair plan support device. Figure 14 is a diagram showing an example of the hardware configuration of the server 1. The server 1 is composed of, for example, a processor 91, a storage device 92, a display device 93, an input device 94, and a communication interface 95 shown in Figure 14.

The processor 91 is a CPU (Central Processing Unit, also known as a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP (Digital Signal Processor)), a system LSI (Large Scale Integration), or the like. The storage device 92 is a RAM (Random Access Memory), a ROM (Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (registered trademark), an Electrically Erasable Programmable Read Only Memory, a hard disk drive, or the like. The display device 93 is an LCD monitor, display, or the like. The input device 94 is a mouse, keyboard, touch panel, or the like. The communication interface 95 is a network interface card, or the like.

The server 1's deformation information acquisition unit 13, repair method extraction unit 14, cost calculation unit 15, and construction period calculation unit 18 are realized by the processor 91 executing programs for operating as each of these units. The programs for operating as the deformation information acquisition unit 13, repair method extraction unit 14, cost calculation unit 15, and construction period calculation unit 18 are pre-stored in the storage device 92. The processor 91 reads and executes the programs from the storage device 92, thereby operating as the deformation information acquisition unit 13, repair method extraction unit 14, cost calculation unit 15, and construction period calculation unit 18.

The programs stored in the storage device 92 for operating as the deformation information acquisition unit 13, repair method extraction unit 14, cost calculation unit 15, and construction period calculation unit 18 may be provided to users, etc., in a form written to a storage medium such as a CD (Compact Disc)-ROM or DVD (Digital Versatile Disc)-ROM, or may be provided to users, etc. via a network.

Furthermore, the memory unit 11 is realized by the memory device 92.

Note that while the hardware configuration of server 1 has been described, the hardware configuration of client 2 is similar.

As described above, the repair planning support system 100 according to this embodiment determines whether scaffolding is required when it receives from the user an operation to select the area to repair the object to be repaired, an operation to specify the deformation to be repaired from among the deformations included in the selected area, and an operation to specify the repair method to be implemented from among the repair methods that can repair all deformations to be repaired. If scaffolding is required, the repair planning support system 100 receives from the user an operation to specify the scaffolding installation area by polygon input and determines candidates for scaffolding to be installed in the specified installation area. Furthermore, when the repair planning support system 100 receives from the user an operation to select scaffolding to be installed from among the scaffolding candidates, it calculates the cost of the repair work, including the cost of scaffolding installation, and notifies the user. If scaffolding is not required, the repair planning support system 100 calculates the cost of the repair work, excluding the cost of scaffolding installation, and notifies the user. In addition, the repair planning support system 100 calculates the duration of repair work specified by the user based on information about repair work carried out in the past, and then determines the schedule for the repair work.

The repair planning support system 100 according to this embodiment is capable of calculating repair costs and construction periods for an area selected by the user, enabling highly accurate estimates of repair costs and construction periods even when repair work is being carried out on only a portion of a structure. Furthermore, repair costs are calculated taking into account the need for scaffolding and the type of scaffolding that can be applied to the area covered by the repair work, making it possible to calculate repair costs under conditions that reflect the actual state of the repair work.

In the present embodiment, the repair plan support system 100 receives a range specification on the display screen of the 3D point cloud of the object to be repaired and creates a list of deformations included in the specified range. However, the method of creating the deformation list is not limited to this. For example, the repair plan support system 100 may have the user select the structure to be repaired, create a list of deformations included in the specified structure, notify the user, and allow the user to select the deformations to be repaired. Furthermore, when the user selects the structure to be repaired, the repair plan support system 100 may automatically select a range so that all deformations occurring in the object to be repaired are included, and designate the selected range as the range to be covered by the repair work. Even when such a selection method is used, repair costs can be calculated with high accuracy, taking into account the need for scaffolding installation.

Embodiment 2.
FIG. 15 is a diagram showing a configuration example of a repair plan support system 100a according to the second embodiment. The repair plan support system 100a has a configuration in which the server 1 of the repair plan support system 100 according to the first embodiment is replaced with a server 1a. The server 1a has a configuration in which the information processing unit 12 of the server 1 according to the first embodiment is replaced with an information processing unit 12a, and the information processing unit 12a has a configuration in which an additional work proposal unit 19 is added to the information processing unit 12 of the server 1 according to the first embodiment. In FIG. 15, the same components as those in the repair plan support system 100 according to the first embodiment are assigned the same reference numerals. Descriptions of the components assigned the same reference numerals as those in the first embodiment will be omitted.

The additional work proposal unit 19 provided in the information processing unit 12a of server 1a checks whether there are any abnormalities around the area specified by the user that can be repaired together with the abnormalities within the specified area, and if any abnormalities exist, proposes that these abnormalities also be subject to repair work.

Next, we will explain the operation of the repair plan support system 100a according to the second embodiment. Note that we will omit explanations of operations that are common to the repair plan support system 100 according to the first embodiment.

Figure 16 is a flowchart showing an example of the operation of the repair plan support system 100a according to the second embodiment. In Figure 16, the same step numbers are assigned to the same processes as in the flowchart of Figure 8 described in the first embodiment. Explanations of processes assigned the same step numbers as in Figure 8 will be omitted.

In the repair planning support system 100a, after the client 2 executes step S113, the server 1 checks whether there are any deformations of the same type around the selected range (step S221). Specifically, the additional work proposal unit 19 checks whether there are any deformations of the same type as the deformation to be repaired around the selected range, which is the range of the point cloud selected in step S102. For example, the additional work proposal unit 19 expands the selected range using a predetermined method, and if there is a deformation that is not included in the selected range before expansion but is included in the selected range after expansion, it determines that there are any deformations of the same type around the selected range.

If there are no deformations of the same type around the selected range (step S221: No), the process proceeds to step S114. If there are deformations of the same type around the selected range (step S221: Yes), the server 1 expands the size of the polygon to match the range of the deformations (step S222). Note that the size of the polygon displayed on the screen by the client 2 is not changed. In step S222, the size information of the polygon used in processing on the server 1 is changed. The change in size information is performed by the additional work proposal unit 19.

The server 1 then checks whether the additional scaffolding costs incurred due to the change in polygon size are within the allowable range (step S223). Specifically, the additional work proposal unit 19 calculates the difference between the cost of installing scaffolding to match the pre-change polygon size and the cost of installing scaffolding to match the changed polygon size, and checks whether the difference is below the upper limit value previously specified by the user. The cost of installing scaffolding to match the changed polygon size is, for example, the cost of scaffolding for which the changed polygon size satisfies the "scaffolding installation conditions" in the scaffolding information (see Figure 5). The cost is calculated based on the "unit" and "unit price." If there are multiple scaffoldings that satisfy the "scaffolding installation conditions," the cheapest price is used.

If the additional scaffolding costs are not within the allowable range (Step S223: No), the process proceeds to Step S114. If the additional scaffolding costs are within the allowable range (Step S223: Yes), the server 1 creates a proposed change to the work content (Step S224). Specifically, the additional work proposal unit 19 creates information including changes to the selected range (the range where repair work will be performed), changes to the deformation to be repaired, and changes to the work costs as proposed change information for the work content.

Note that while we have discussed creating a proposed change to the work content when the additional cost of scaffolding is within the acceptable range, it is also possible to create a proposed change to the work content when the additional cost of the entire repair work is within the acceptable range.

The additional work proposal unit 19 sends the created change proposal information to the client 2. Based on the received change proposal information, the client 2 displays a proposal screen for proposing changes to the repair work content to the user (step S121). The client 2 displays, for example, screen 304 shown in FIG. 17 as the proposal screen. FIG. 17 is a diagram showing an example of a screen display for proposing changes to the repair work content. For example, as shown in FIG. 17, the client 2 displays information about the work content before the change in the center of screen 304 and information about the work content after the change on the right side of screen 304. To make the changes easier to see, display methods such as changing the text color or background color of the parts that will be changed according to the proposal may be used. In addition, buttons 341 and 342 are displayed in the lower right corner of screen 304 to allow the user to select whether or not to change the work content in accordance with the proposal.

The client 2 checks whether to change to the proposed content (step S122). That is, the client 2 checks whether the selection operation unit 23 has accepted that the user has pressed the "Change" button 342 on the screen 304, or whether the selection operation unit 23 has accepted that the user has pressed the "Do not change" button 341.

If the proposed content is not to be changed (step S122: No), the process proceeds to step S114. At this time, the client 2 terminates the display of screen 304 and returns to the display of screen 301. Screen 301 is the same as screen 301 shown in FIG. 11. If the proposed content is to be changed (step S122: Yes), the client 2 notifies the server 1 of the change to the proposed content, and the server 1 updates the information on the construction details (step S225). At this time, the client 2 terminates the display of screen 304 and returns to the display of screen 301. On the server 1, the various parts of the information processing unit 12a update the information on the construction details. For example, the basic cost calculation unit 16 calculates the basic cost for carrying out the construction according to the proposed content, and the incidental cost calculation unit 17 calculates the basic cost for carrying out the construction according to the proposed content. The server 1 transmits the information on the updated construction details to the client 2. Upon receiving the information on the updated construction details, the client 2 updates the display content on screen 301 based on the received information and executes step S114.

As described above, when a user specifies an area for repair work to be performed on a defect, the repair plan support system 100a according to the second embodiment checks whether there are any defects around the specified area that can be included in the repair work. If any defects exist, the repair plan support system 100a proposes adding the defects around the specified area to the repair work. When determining whether to make a proposal, the repair plan support system 100a takes into account the additional costs that would be incurred by changing the work content. Furthermore, when proposing a change to the work content, the repair plan support system 100a displays on a single screen the work costs if the defect to be included in the repair work is not added and the work costs if the defect to be included in the repair work is added. The repair plan support system 100a according to the present embodiment can propose a change to the repair work content if it is possible to perform repair work more efficiently than if the repair work were performed with the content specified by the user. Furthermore, when the user decides whether to change the repair work content, the difference between the costs of changing the repair work content and not changing it can be easily confirmed.

The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or different embodiments may be combined with each other. Parts of the configuration may also be omitted or modified without departing from the spirit of the invention.

For example, in each embodiment, a server and a client constitute a repair planning support system, but it is also possible to configure a single device to perform each process executed by the server and each process executed by the client.
