Description

  The present invention relates to a technology such as an information processing system and the like, and relates to a technology for monitoring, collecting, analyzing, visualizing, and inspecting and repairing work of a deterioration state of a structure.

  Since the structure is deteriorated or damaged due to aging or disaster due to aging, it is necessary and important to perform inspection and repair work for maintenance. The structures include various public structures such as roads, railways, bridges, tunnels, water supply facilities, sewerage facilities, electrical facilities, and communication facilities, infrastructure facilities, and general buildings such as houses and buildings. Examples of states such as deterioration of the structure include cracks, rust, corrosion, and peeling. A predetermined manager or business operator (also referred to as an operator or the like) carries out a work for inspecting or repairing the deterioration state of the structure. For example, the Ministry of Land, Infrastructure, Transport and Tourism has established laws and regulations relating to maintenance and management of public structures or those entrusted with management perform regular inspections and repairs of public structures. For example, local government organizations carry out periodic inspection work by staff or contractors. In periodic inspection work, the operator basically moves to the location of the target structure, diagnoses the deterioration status of each part by visual inspection (visual confirmation), and performs repair work depending on the deterioration status. In addition, managers create plans for future inspections and repairs of structures, and work according to the plans.

  The conventional structure inspection / repair work requires a large number of personnel, man-hours, and costs, and therefore, general problems include efficiency of inspection / repair work and cost reduction. In addition, if inspection and repair are not performed at an appropriate date and time, it will lead to an increase in costs due to oversight of the deterioration status, etc. Therefore, it is desirable to create an appropriate inspection and repair plan.

  In view of the above background, there is a need for an information processing system and the like for supporting labor and inspection of structures and saving labor and increasing efficiency. As an example of such a system, a system that collects monitoring data by monitoring the status of a structure, analyzes the degradation status based on the monitoring data, and visualizes the degradation status on a screen has been proposed.

  The following are examples of prior art examples of means (subsystem) for monitoring the deterioration status of structures and collecting monitoring data. As a first example, a device such as a predetermined sensor or camera is installed in the vicinity of the target structure, and a collection device that cooperates with the device is installed. The device detects and outputs sensor data and images. The collection device automatically collects sensor data, images, and the like from the device as monitoring data through wireless communication or the like. The collection device transmits the collected monitoring data and the like to a device such as a remote server.

  As a second example, an operator carries a mobile terminal device, moves to the location of the target structure, and monitors sensor data, images, and the like from the target structure using a sensor, camera, or the like included in the mobile terminal device. Obtain and collect as data. The mobile terminal device transmits monitoring data and the like to a device such as a remote server.

  As a prior art example regarding the information processing system that supports the inspection and repair work of the structure, there are JP-A-2008-255570 (Patent Document 1) and JP-A-2016-133320 (Patent Document 2).

  Patent Document 1 describes a diagnostic data collection system for large structures. In this system, a sensor module and a data recording device are installed on a bridge. The sensor module periodically measures data for diagnosis (sensor information) and stores the data in a data recording device wirelessly. Data stored in the data recording device is collected by a data collection device of the traveling vehicle. The collected data of the data collection device is input to the diagnosis device and subjected to deterioration diagnosis.

  Patent Document 2 describes a damage status determination system and the like. In this system, a worker photographs an object using the camera function of a tablet terminal (inspection terminal). The captured image is transmitted from the tablet terminal to the determination system (server). The determination system determines the degree of damage (deterioration state) by comparing the captured image with the already captured image.

[DB]
The structure master DB 26 is a DB for managing master data of basic information, structure information, and related information of the structure 1. The basic information includes, for each structure 1, a structure ID, name, structure type, installation location (position information on the map), installation date, and the like. The structure information includes information on structures, members, etc. for each structure ID, and may include structure appearance photographic images, three-dimensional model data (for example, data by CAD), and the like.

  The regional characteristic master DB 25 is a DB for managing regional characteristic master data. The regional characteristic information is information for reflecting the regional characteristics according to the installation location (position) of the structure 1. The regional characteristic information includes information such as regional classification, the presence / absence of snowfall, the presence / absence of salt damage, and third party damage information. The regional classification includes, for example, an urban area, a plain coastal area, a remote island, or a mountainous area. Depending on various regional characteristics, there is a difference in the ease of occurrence and progress of deterioration, which are set in association with each other as a numerical value. In the deterioration analysis process of the deterioration analysis unit 12, the progress from the current deterioration degree to the future deterioration degree is predicted according to the region characteristics, and a predicted value of the future deterioration degree is calculated. For example, in the case of a structure 1 (for example, a normal road) whose regional characteristics are standard, it is assumed that the time taken for the progress of deterioration from one deterioration level to the next deterioration level is two years. On the other hand, in the case of the predetermined structure 1 whose regional characteristic is the predetermined regional characteristic, the time taken for the degradation progress from one degradation level to the next degradation level is one year. That is, in the case of the structure 1 having a predetermined regional characteristic, the deterioration progressing speed is doubled. When the inspection / repair plan creation visualization unit 14 prepares an inspection / repair plan for the structure 1 having the predetermined regional characteristics, the inspection repair / repair time, the time and method of the inspection / repair, Select the construction method.

  The inspection / repair priority master DB 27 is a DB for managing inspection / repair priority. The inspection / repair priority is a priority parameter that can be set for each structure 1, and represents a priority regarding inspection / repair in the plurality of structures 1. This priority is taken into account when preparing an inspection and repair plan. This priority, for example, gives priority to inspections and repairs of emergency transport roads and structures (for example, road signs and road structures) installed on those roads over inspections and repairs of other roads and structures. It is stipulated. In addition, for example, priority is given to inspection and repair of a route with a large amount of traffic and structures installed on the route. For example, in a structure type and a layer called a road, a type such as a normal road or an emergency transport road is further set between a plurality of roads, and a type corresponding to the amount of traffic is set. A priority is set for each of the plurality of roads. For example, the priority values are set to 1 (high), 2 (medium), 3 (low), 3 (low) for normal roads, and 1 (high) for emergency transport roads.

  The inspection / repair method master DB 28 is a DB for managing information on various known inspection methods and repair methods that are selectable candidates for the inspection / repair work. The inspection method and repair method are selected when the inspection / repair plan is created. The information on the inspection method and the repair method includes, for example, an ID (inspection method ID, repair method ID) for each of the plurality of inspection methods and each of the plurality of repair methods. Further, according to the structure type, the deterioration type, and the degree of deterioration, candidate inspection methods and repair methods are set in association with each other. Further, since an appropriate cost is required for each inspection method and repair method, the cost (for example, a cost value that is an estimated approximate value of the cost required for each year) is set in association with each other. The inspection / repair plan creation visualization unit 14 creates an inspection plan and a repair plan using such information on the inspection method and the repair method. For example, regarding a crack on a road, what kind of inspection method or repair method should be applied as a candidate is set in association with each deterioration level.

  Although not particularly limited, examples of the inspection method include an appearance visual inspection method, a hammering inspection method, a cross-sectional inspection method, and the like. Examples of the repair method (including the reinforcement method) include a surface coating method, a crack injection filling method, a cross-sectional repair method, an anticorrosion method, a concrete winding method, and a steel plate bonding method.

At that time, the user terminal cooperation unit 15 provides basic screen data. The user selects use of the inspection / repair plan function on the basic screen.

  On the basic screen (or the screen for inspection and repair plan function), the user selects and inputs conditions such as the desired structure 1 whose scope is to be created, its range, structure type, etc. (for example, as in the degradation status visualization function) Can be selected). Further, the user selects and inputs a period for which a plan is to be created on the screen as a condition. This period is, for example, a period for each fiscal year, and a plan start year and a plan end year (or plan years) can be designated. Further, the user can specify the budget upper limit value for each year on the screen as a condition. In the embodiment, the plan and the budget are in units of a year, but are not limited thereto and can be set. After selecting the conditions, the user inputs an instruction to create an inspection / repair plan (specifically, for example, input of a plan creation button).

  (S32) The user terminal cooperation unit 15 receives information including conditions regarding the inspection / repair plan function from the user terminal 4. The user terminal cooperation unit 15 searches the inspection / repair plan DB 24 according to the conditions, and acquires corresponding visualization data as a search result. As a modification, the inspection / repair plan creation visualization unit 14 may perform such processing.

  The user terminal cooperation unit 15 configures screen data for the inspection / repair plan screen using the acquired visualization data, and transmits the screen data to the user terminal 4. If there is no data corresponding to the condition, the process ends as an error.

  (S33) The user terminal 4 receives screen data from the user terminal cooperation unit 15, and displays an inspection / repair plan screen based on the screen data. Thereby, the user can confirm the inspection and repair plan of the structure 1 on the screen. The user can perform a confirming operation when adopting the presented inspection / repair plan (plan), canceling when not adopting it, and performing a correcting operation when modifying. The data of the adopted plan is stored in the inspection / repair plan DB 24. Administrators can perform inspection and repair work according to the plan.

  In addition, when an administrator or the like actually performs inspection and repair work according to a plan, the results can be registered on the screen provided by the visualization system 3. In that case, for example, the result registration function is used on the screen of the user terminal 4, the plan information is displayed on the screen, and the result registration operation can be performed for each inspection item or repair item in the plan. The visualization system 3 stores the performance information in association with the plan information. When the inspection and repair results are registered, the user can check the results in association with the plan on the screen.

  Moreover, although mentioned later, the user terminal cooperation part 15 (inspection repair plan creation visualization part 14) selected the item (structure item) for some structures in the inspection repair plan from the user terminal 4. In this case, screen data for visualizing the plan of the structure unit is provided. Similarly, when an item (year item) for a part of the year in the inspection / repair plan is selected, screen data for visualizing the plan for that year is provided.

[Deterioration analysis]
In the degradation analysis process of the degradation analysis unit 12, the degradation location, the degradation type, the degradation degree, and the like of the structure 1 are determined. The method for the degradation analysis process is not particularly limited. The deteriorated portion is represented by, for example, two-dimensional or three-dimensional coordinates. Degradation types include, for example, cracks, rust, corrosion, and peeling. The degree of deterioration is expressed by a numerical value or level. In the deterioration analysis process, a deterioration state such as a future deterioration degree is predicted from a deterioration state such as a current deterioration degree. Based on the deterioration analysis data, the deterioration analysis unit 12 predicts the degree of deterioration at the future time from the degree of deterioration of the structure 1 at the present time and the past time, and the predicted value of the degree of future deterioration, etc. Generate data. If there is at least information on the current degradation status, the future degradation status can be predicted with a certain degree of accuracy. In the deterioration prediction, a known method can be applied, and prediction can be made based on knowledge in the field of the target structure 1.

[Deterioration status visualization function]
The degradation status visualization function includes a superimposed display function and a time series display function. The superimposing display function is a function that superimposes and displays the overall deterioration status of the target structure 1 specified by the user, among the plurality of types of target structures 1. . The time series display function is a function for switching and displaying the deterioration status of the target structure 1 designated by the user in a time series (past, present, future).

  With the superimposed display function, the user can easily understand the deterioration status of the desired plurality of structures 1 including the overall relationship, and can easily determine the structures 1 and the like that need inspection and repair.

  With the time series display function, the user can easily understand the time series changes and progress of the deterioration state of the target structure 1, and can easily determine the structure 1 or the like that needs to be inspected or repaired. The future deterioration state is displayed based on deterioration state analysis data including the degree of future deterioration by the deterioration prediction process of the deterioration analysis unit 12.

[Inspection and repair plan creation visualization function]
The inspection / repair plan creation visualization function has an inspection / repair plan display function, a cost graph display function, an inspection / repair result display function, and the like as described below. The inspection / repair plan creation visualization function creates an inspection / repair work plan (overall plan) for the target structure 1 in a table format that includes information for each target structure 1 and each target period (year). Has a function to display. In addition, the inspection / repair plan creation visualization function has a function of creating and displaying an approximate cost required for inspection and repair as a graph along with the inspection / repair plan. The inspection / repair plan creation visualization function displays the plan table and the cost graph in association with each other in the screen. The inspection / repair plan creation visualization function has a function of displaying plan information for each structure and a function of displaying plan information for each year in the inspection / repair plan. In addition, the inspection / repair plan creation visualization function has a function of comparing and displaying the result information of the execution of the inspection / repair work together with the inspection / repair plan.

  The inspection / repair plan creation visualization unit 14 comprehensively considers these inspection / repair plans and cost graphs, considering the deterioration status of each structure 1, inspection / repair priority, inspection method and repair method, upper limit of budget, etc. Create. The user can variably set the inspection / repair priority, inspection method / repair method, budget upper limit value, and the like.

  The inspection / repair plan creation visualization unit 14 considers the deterioration state (at least the current deterioration state) such as the deterioration type and the deterioration degree (including the past deterioration prediction) of the structure 1 for each structure 1. In addition, the necessity of inspection and the necessity of repair are judged every year. For example, when the degree of deterioration is up to a predetermined threshold, it can be determined that the inspection is handled, and when it exceeds the predetermined threshold, the repair is handled. The inspection / repair plan creation visualization unit 14 determines and selects the inspection / repair time (year), the inspection method and the repair method for the structure 1 to be inspected / repaired. The inspection / repair plan creation visualization unit 14 determines the inspection / repair plan in consideration of the cost and budget for each year.

  As an example, it is assumed that the deterioration level relating to a certain deterioration type of a certain structure type includes deterioration level 1 (small), deterioration level 2 (medium), deterioration level 3 (large), and the like. For example, in the case of deterioration level 2, it is selected as a response to perform inspection, and in the case of deterioration level 3, it is selected as a response to perform repair. An inspection method or a repair method is selected according to the type of deterioration, the degree of deterioration, and the budget. In addition, an inspection interval for inspection (for example, every year, every two years, etc.) is also selected. Also, the inspection and repair timing is selected according to the inspection and repair priority. For example, a structure with a high priority is selected so that the inspection and repair time is relatively earlier than that of a structure with a lower priority. Further, for example, a structure with a high priority is selected so as to be inspected or repaired within a limited budget (budget upper limit value) more reliably than a structure with a lower priority than that.

[Relationship between functions and screens]
FIG. 6 shows the relationship between each function and screen provided by the visualization system 3. First, although not shown, there is a basic screen. The user can log in to the basic screen from the user terminal 4 and perform system basic settings, user settings, and the like. The user can use each function from the basic screen.

  The following screens are provided by the visualization system 3. As a screen (degradation status visualization screen) provided by the degradation status visualization function, a screen G1 for visualizing the degradation status of the plurality of structures 1 and a screen G2 for visualizing the details of the degradation status of the individual structures 1 are provided. As a screen (inspection / repair plan screen) provided by the inspection / repair plan creation visualization function, a screen G3 for visualizing an inspection / repair plan for the whole of the plurality of structures 1 and a screen G4 for visualizing the inspection / repair plan for individual structures 1 And a screen G5 for visualizing the inspection / repair plan for each year. The display of each screen may be a transition between screens, or other screen information may be displayed in a pop-up (superimposed display) within a certain screen.

[Screen of degradation status visualization function (1)]
FIG. 7 shows a configuration example of a degradation status visualization screen provided by the degradation status visualization function. In particular, a screen G1 for visualizing the deterioration status of the plurality of structures 1 is shown. The user can specify the desired target structure 1 on the screen G1, and can check the deterioration status and create an inspection / repair plan (link to the screen G3) for the specified structure 1.

  In the present example, public structures targeted by users such as a manager include various types of roads, bridges, tunnels, and the like. Further, for example, a structure type (large category) called road has roads, road signs, road structures, and the like as more detailed types. That is, the structure type has a hierarchical structure.

  This screen G1 includes a superimposed display area 701, a condition selection field 702, a time selection bar 703, and the like. The superimposed display area 701 displays the structure 1 (one or more, one or more) selected by the user as an image in which a plurality of layers are superimposed. In other words, the superimposed display area 701 is a structure deterioration situation map. In the superimposed display area 701, the deterioration status of the year selected by the user (the current deterioration status by default) is displayed. An example of the layer structure of the superimposed display area 701 is shown on the lower side of FIG. A layer is assigned to each structure type. There is a background layer at the bottom, and a general map is set in the background layer. The background layer can also be set as blank. A plurality of layers are provided on the background layer. For example, a road is assigned to the first layer, a road sign is assigned to the second layer, and a road structure is assigned to the third layer. The assignment is variable according to the user's selection.

  In the superimposed display area 701, based on the structure information and the deterioration analysis result information, the position (positional relationship) and the deterioration state regarding the plurality of types of structures 1 are displayed. The position can be confirmed as a position on the map. The deterioration status is displayed in a distinctive manner using an expression using a predetermined color or image according to the deterioration type, the deterioration degree, and the like. For example, roads are displayed in different lines and colors depending on the degree of deterioration (deterioration level) for each portion. For example, a portion where the degree of deterioration is large is highlighted. In the superimposed display area 701, a name, an icon, or the like may be displayed for each structure 1, or information may be displayed with a balloon or the like according to a part selection operation.

  In the superimposed display area 701, regional characteristic information may be displayed. For example, the regional characteristics are displayed for each geographical range and each category. In the superimposition display area 701, the inspection / repair priority may be displayed. For example, the priority is expressed by a predetermined color or icon for each structure 1.

The condition selection column 702 is a column for selecting, for example, a structure type, and includes a list and items for selecting a structure type to be displayed in the superimposed display area 701. The condition selection field 702 includes an item for each structure type and an “all” item for designating all structures. For example, there are a “road” item, a “road sign” item, a “road structure” item, a “bridge” item, a “tunnel” item, and the like. In the condition selection field 702, for example, any item is not selected in the initial state (or “all” items may be selected). The user selects an item of a desired structure type that is a target for which the degradation status is to be browsed. For example, when the “road” item is selected, the item is turned on, and the corresponding layer (first layer) of the superimposed display area 701 is turned on, whereby the structure type is road 1 The deterioration status of one or more structures 1 is displayed. Multiple items can be selected simultaneously. The item selection state in the condition selection field 702 is saved as user setting information, and when the screen is displayed next time, the previous screen state is reproduced according to the user setting information. In addition, the item selection state can be stored with an arbitrary name, can be managed multiple times, and can be selected again. The user can select the desired structure 1 in the superimposed display area 701 and the condition selection field 702 of the screen G1. It is. In addition, the condition selection field 702 may display items of a plurality of structures 1 for each structure type so that individual structures 1 can be selected. In the superimposed display area 701, the individual structure 1 can be selected and specified by a user operation. In addition, in the superimposed display area 701, it is possible to select and specify a desired geographical range (one or more structures 1 included in the range) on the map. It is also possible for the user to select an individual structure 1 as a target on the screen G1 and transition to the screen G2.

  In the time selection bar 703, it is possible to select a time point (year) when the deterioration state of the superimposed display area 701 is displayed. The time selection bar 703 includes past, present, and future time points. In the initial state, the current time point (for example, 2017) is selected, and the degradation state corresponding to that time point is displayed in the superimposed display area 701. The user can select a time point by operating the time selection bar 703. The deterioration status at the time of selection is displayed in the superimposed display area 701. The user can check the deterioration status by switching the fiscal year. The past fiscal year can be displayed when past deterioration analysis result information is held. The future year can be displayed as a predicted value of the degree of future deterioration based on the above-described deterioration prediction.

  As an additional function in the modification, the user may select two time points using the time selection bar 702 on the screen G1 and the like, and the deterioration statuses at the two corresponding time points may be displayed in parallel. In this case, the user can check the deterioration status at two points in time.

  As described above, the user can check the overall deterioration state of the desired plurality of structures 1 on the screen G1.

  In addition, when the user selects an individual structure 1 in the superimposed display area 701 or the condition selection field 702 of the screen G1 and designates individual detail display, the screen G2 is displayed. On the screen G2, detailed information on the degradation status regarding the selected individual structure 1 is displayed based on the degradation status analysis data. For example, a photographic image or a three-dimensional model of the structure 1 is displayed, and is displayed so that the detected degradation location in the region of the structure 1 can be seen. In addition, information such as basic information and structure information of the structure 1, monitoring date and time, deterioration type, deterioration degree, and the like are displayed. In addition, enlargement / reduction display is possible according to the user's operation. Further, detailed information may be displayed according to the selection operation of the deteriorated part.

  In addition, information for each structure 1 may be set in the superimposed display area 701 of the screen G1. When the user wants to set information (for example, inspection / repair priority) for each structure 1, select the structure type and the individual structure 1 in the superimposed display area 701 and the condition selection field 702, and specify the settings. (For example, right-click to select “Settings”). Thereby, information can be set in the structure 1.

  Similarly, the plan creation target structure 1 may be selectable in the superimposed display area 701 of the screen G1. The user selects the structure type and the individual structure 1 (one or more) in the superimposed display area 701 and the condition selection field 702, and specifies the plan creation. Thereby, the inspection repair plan regarding the structure 1 can be created.

  Further, as an additional function in the modified example, there is a function of displaying inspection and repair information of the structure 1 in the superimposed display area 701. When a later-described inspection / repair plan is created, information corresponding to the plan table is displayed in the superimposed display area 701. For example, the user selects a desired structure, year, inspection and repair items from the plan table, and designates a map display. In that case, the structure and information on inspection or repair of the year are displayed in the superimposed display area 701 in a predetermined color or icon (for example, an inspection icon or a repair icon). Similarly, in the case where inspection and repair record information has been registered, the check and repair record may be displayed in a predetermined color or image in the superimposed display area 701.

[Screen of degradation status visualization function (2)]
FIG. 8 shows another display example on the degradation status visualization screen (screen G1). In this example, the time selection bar 703 is used to switch and display the state of deterioration status at the designated time point (past, present, future) of the designated structure 1 (for example, only the road) in the superimposed display area 701. FIG. 8A shows a deterioration state at a past time point (for example, 2015). FIG. 8B shows a deterioration state at the current time point (for example, 2017). FIG. 8C shows a deterioration state at a future time (for example, 2019). In this example, the degradation levels include degradation level 1 (small), degradation level 2 (medium), and degradation level 3 (large). For example, the degradation level 1 (small) portion is displayed with a blue solid line, the degradation level 2 (medium) is a yellow broken line, and the degradation level 3 (large) portion is displayed with a red broken line and a highlight frame. A structure ID or name is also displayed on each road portion.

[Inspection and repair plan function screen (1)]
FIG. 9 shows a configuration example and a display example of an inspection / repair plan screen (screen G3) by the inspection / repair plan function. A plan table (inspection / repair plan) 801 is displayed on the lower side of the screen G3, and a cost graph 802 is displayed on the upper side in an associated state (both year axes match). In this example, a plurality of (five) structures # 1 to # 5 of a certain kind of structure (for example, road) are designated as the structure 1 to be planned. In addition, a range from the current 2015 to the future 2020 is designated as the period for which the plan is to be created. The plan period is 6 years, the plan start year is 2015, and the plan end year is 2020. Further, as shown in the expense graph 802, a budget upper limit value (for example, 2.2 M ¥ = 22.2 million yen) is set as a condition, and the user can change it by operation.

  In this example, the budget for the target structure is a yearly budget, and the inspection and repair for the target structure are corresponding to the yearly inspection and repair. The unit of time for budget, inspection and repair is not limited to a year unit, but can be set in a predetermined unit of time (for example, a month unit smaller than the year).

  Further, in this example, when the plan is created, the cost for each year (the total value of the inspection cost and the repair cost) is created so as not to exceed the budget upper limit value. Not limited to this, it is also possible to create a plan without setting a budget upper limit value. The budget upper limit is set to the total cost upper limit, but is not limited to this, and may be the inspection budget upper limit or the repair budget upper limit. The budget may be different for each type of structure or different for each year. Setting is also possible.

  The inspection / repair plan creation visualization unit 14 inputs a target structure, a plan period, a budget upper limit value, and the like as conditions for creating a plan based on a user's operation, and a plan corresponding to the inspection / repair plan based on them. A table 801 is created. The screen G3 includes a plan creation button, setting fields for conditions such as a plan period, and the like. The plan period may be changeable by operating the right end of the plan table 801 left and right.

  The plan table 801 takes, for example, each structure 1 (for example, # 1 to # 5) for each row and each year of the planning period (for example, 2015 to 2020) for each column, and checks items that intersect in the matrix. / It has a configuration for displaying repair items. As the inspection / repair item, a value of “inspection” or “repair” is displayed, and this may be a character or an image such as a predetermined symbol or icon. Blank indicates no inspection or repair. For example, regarding structure # 1, inspection is set as a schedule in FY2015, repair in FY2017, and inspection in FY2019.

  The cost graph 802 displays the cost related to the plan in the plan table 801. The cost graph 802 is a bar graph, for example, and has a configuration in which the horizontal axis indicates the year corresponding to the plan period of the plan table 801 and the vertical axis indicates the cost for each year. For example, the cost is displayed separately from the inspection cost and the repair cost. The total cost of both can be displayed. In the expense graph 802, a budget upper limit value is also displayed, and can be changed by a predetermined operation (dragging or numerical input).

  As described above, the user can confirm the contents of the inspection / repair plan automatically generated by this function on the screen G3. When the user adopts the plan, the user designates the plan storage. The inspection / repair plan creation visualization unit 14 stores the data of the adopted plan in the inspection / repair plan DB 24. Administrators perform inspection and repair work in accordance with the plan, and register performance information as necessary.

  If there is a track record of inspections and repairs performed by the manager or the like according to the plan, the track record information can be entered on the screen. In that case, the visualization system 3 accepts a record input on the record registration screen or the screen G3. For example, on the screen G3, the user selects an inspection item or a repair item (corresponding to an item where the structure item and the year item intersect) in the plan table 801, and designates result registration (such as right-clicking). As a result, the visualization system 3 stores the result information in association with the inspection or repair item. When the record information has been registered, record information can be displayed on the screen (for example, screens G4 and G5) in a state associated with the plan information.

  In the plan table 801 on the screen G3, the user can select a desired structure (for example, the structure item 803) or a desired year (for example, the year item 804). The screen G4 and the screen G5 can be displayed according to the selection operation (for example, click, tap, etc.).

[Screen of inspection / repair plan function (2)]
FIG. 10 shows an example of a screen G4 that displays plan information for each structure. When the structure item 803 is selected on the screen G3, the screen G4 (balloon portion) is displayed. The screen G4 includes plan summary information 901 and a plan details table 902. The plan summary information 901 and the plan details table 902 include result information when the results are registered. In the plan summary information 901, the structure ID or name (example: structure # 1), structure type (example: road), planning period (example: FY2015-2020), inspection cost (plan and actual result), repair cost Includes information such as (planned and actual).

  The plan details table 902 takes a year and a total for each row, and has an inspection plan, a repair plan, an inspection result, and a repair result as columns. Further, the inspection plan column includes an inspection method and cost column, and the repair plan column includes a repair method and cost column. For example, looking at the rows in FY2015, with respect to the inspection items in the plan table 801, values of the inspection method (example: “method A”) and cost (example: 0.4 M ¥) are set in the inspection plan column. . In addition, regarding the repair items in the plan table 801, values of repair method (example: “method A”) and cost (example: 0.3 M ¥) are set in the repair plan column. Similarly, when there is a record registration, values are set in each column. Regarding the actual results, if the inspection method / repair method and cost differ from the plan, different values can be registered. In the total line, the total inspection cost (for example, 0.85 M ¥) and the repair cost (for example, 0.3 M ¥) for the planning period are displayed.

  As described above, the user can confirm the inspection / repair plan for each structure 1 in an easy-to-understand manner on the screen G4, and can also confirm the comparison with the actual results. The result display can be confirmed in an easy-to-understand manner, for example, by displaying the plan and the result in parallel. As another example of the result display, it may be displayed in parentheses in each item value of the plan.

[Screen of inspection and repair plan function (3)]
FIG. 11 shows an example of a screen G5 that displays plan information for each fiscal year. When the year item 804 is selected on the screen G3, the screen G5 (balloon portion) is displayed. The screen G5 includes plan summary information 1001 and a plan schedule 1002 for 2015. The plan summary information 1001 and the plan schedule 1002 also include record information when record registration is completed. The plan summary information 1001 includes information such as the fiscal year, inspection costs (planned and actual results), repair costs (planned and actual results), and the like.

  The plan specification table 1002 takes the structure and total for each row, and has an inspection plan, a repair plan, an inspection result, and a repair result as columns. Further, the inspection plan column includes an inspection method and cost column, and the repair plan column includes a repair method and cost column. For example, in the inspection plan column, the inspection method (example: “method A”) and cost (example: 0.4 M ¥) are set for the inspection item of the structure # 1 in the plan table 801. In the repair plan column, the repair method (example: “Method D”) and cost (example: 1.6 M ¥) are set for the repair item of the structure # 4 in the plan table 801. Similarly, when there is a record registration, values are set in each column. In the total line, the total inspection cost (for example, 0.4 M ¥) and the repair cost (for example, 1.6 M ¥) for the year are displayed.

  As described above, the user can easily check the inspection / repair plan for each year on the screen G5, and can also check the comparison with the actual results.

[Display example when modifying a plan]
FIG. 12 shows a configuration example when the user modifies the inspection / repair plan on the screen G3. (A) of FIG. 12 shows the plan of the state before correction about the plan table 801 which the visualization system 3 produced | generated. FIG. 12B shows a plan in a state after the plan in FIG.

  The visualization system 3 (inspection / repair plan creation visualization unit 14) has a function of regenerating the entire plan and a function of correcting a part of the plan. First, the function of regenerating the entire plan can be realized by inputting a plan creation button after the user changes the condition on the screen G3. The inspection / repair plan creation visualization unit 14 newly generates a plan under the conditions. When the user confirms the contents of the inspection / repair plan once generated under certain conditions on the screen G3, etc., and wants to review the contents of the plan as a whole, this function is used to set the conditions (for example, the plan period, budget upper limit value). Etc.) and generate a plan again. The user can also create and save a plurality of plans and use them for comparative studies.

  The function to modify a part of the plan can be realized as follows. In the plan table 801 on the screen G3, the user selects a desired inspection / repair item to be corrected and performs an operation of moving. In this example, as a modification example, a case where the repair item 1101 in the structure # 4 in the fiscal year 2015 is changed to a repair item 1102 in the fiscal year 2016 is shown. With this function, the user can intentionally change some item parts in the plan of the plan table 801 without changing other item parts.

  For example, when the user wants to change only the schedule for this part of the repair item 1101 for the structure # 4 in FY2015 for some reason, the user selects the repair item 1101 and moves it in the direction of the horizontal year ( Drag, swipe, etc.). For example, the user shifts the repair item 1101 to the blank of the next 2016 in consideration of the budgets for 2015 and 2016, and sets the repair item 1102 in a state. Thereby, a part of the plan is corrected. The user can save the revised plan by inputting the plan save button.

  The inspection / repair plan creation visualization unit 14 also corrects and updates the cost graph as the inspection / repair time (year) changes when the plan is corrected.

  As a modified example, a modified version plan may be automatically generated so as to review the entire plan of the plan table 801 in accordance with an operation for partially correcting the inspection / repair item. For example, as in the above example, when the user shifts the repair item 1101 to the repair item 1102, the schedule of the structure # 4 may be reviewed after the 2017 fiscal year. The schedules of the structures # 1, # 2, # 3, and # 5 may be reviewed. For example, if there is an item for inspection or repair after FY2017, the item may be corrected to be shifted to the future. In addition, for example, when the repair item 1102 is to be included in the fiscal year 2016, the cost for the fiscal year 2016 is calculated, and it is checked whether or not the cost exceeds the budget upper limit value for the fiscal year 2016. As a result of the check, if the budget upper limit value is exceeded, modification of the repair item 1102 may be denied and a message may be output to the user indicating that the budget upper limit value is exceeded. Alternatively, as a result of the check, if the budget upper limit value is exceeded, a message confirming whether or not the budget upper limit value is exceeded may be output to the user, and correction may be made based on the confirmation input operation.

[Deterioration prediction and planning considering regional characteristics]
FIG. 13 shows an example of a deterioration degree prediction and inspection / repair plan reflecting and reflecting regional characteristics. With respect to a certain structure type (for example, road) and deterioration type (for example, crack), structure # 1 is a standard local characteristic that is relatively difficult to deteriorate, and structure # 2 is a specific structure that is relatively easy to deteriorate. Suppose that it is a regional characteristic. The deterioration analysis unit 12 determines the current deterioration degree (for example, 2015) of each of the structures # 1 and # 2 through deterioration analysis. For example, it is assumed that the deterioration degree of the structure # 1 and the structure # 2 is “deterioration level 1”. The degradation analysis unit 12 predicts the degree of degradation at a future time point based on the current degree of degradation in consideration of regional characteristics. For example, as the prediction of the progress of the deterioration degree of the structure # 1, it is assumed that it progresses to “deterioration level 2” in 2 years (2017) and progresses to “deterioration level 3” in 4 years (2019). . In addition, for example, as a prediction of the progress of the deterioration degree of the structure # 2, when progressing to “deterioration level 2” in one year (2016) and progressing to “deterioration level 3” in two years (2017) Is done.

  The inspection / repair plan creation visualization unit 14 creates an inspection / repair plan based on the deterioration prediction as described above. For example, with respect to the structure # 1, “inspection” is scheduled to be performed in 2017 corresponding to “deterioration level 2” and in the next 2018, and in 2019 corresponding to “deterioration level 3”, “ It is scheduled to carry out “repair”. For example, for structure # 2, “inspection” is scheduled to be implemented in 2016 corresponding to “deterioration level 2”, and “repair” is performed in 2017 corresponding to “degradation level 3”. It is planned to do. As described above, a suitable time for inspection and repair is selected according to the deterioration prediction in consideration of regional characteristics. An inspection method and a repair method are also selected according to the degree of deterioration at each time point (year) and the budget. Further, different inspection methods and repair methods may be selected depending on the regional characteristics.

[Create a plan that takes priority into account]
FIG. 14 shows an example of the deterioration degree prediction and the inspection / repair plan reflecting and reflecting the inspection / repair priority. With respect to a certain type of structure (for example, road) and deterioration type (for example, crack), as the repair priority, structure # 1 has priority = 1 (high), structure # 2 has priority = 2 (medium), and structure Assume that the object # 3 is set to priority = 3 (low). As a result of the deterioration analysis by the deterioration analysis unit 12, it is assumed that the structures # 1, # 2, and # 3 are all “deterioration level 1” as the degree of deterioration of each structure 1 at present (2015). In addition, as prediction values of the degree of future deterioration based on the deterioration prediction, all of the structures # 1, # 2, and # 3 are predicted to progress to “deterioration level 2” in 2017 and “deterioration level 3” in 2019. Suppose there is.

  The inspection / repair plan creation visualization unit 14 creates an inspection / repair plan based on the deterioration prediction as described above. For example, for structure # 2 with priority = 2 (medium), “inspection” is performed in 2017 corresponding to “deterioration level 2”, and “repair” is performed in 2019 corresponding to “deterioration level 3”. It is scheduled to be implemented. For structure # 1 with priority = 1 (high), “inspection” is performed earlier than 2017 corresponding to “deterioration level 2”, for example, one year ago in 2016 and corresponds to “deterioration level 3” For example, it is scheduled to carry out “repair” earlier than 2019, for example, one year ago in 2018. For structure # 3 with priority = 3 (low), “inspection” is performed later than 2017 corresponding to “deterioration level 2”, for example, one year later in 2018, and corresponds to “deterioration level 3” It is scheduled to carry out “repair” later in 2019, for example in 2020, one year later. As described above, in accordance with the priority, the inspection and repair times are selected to be different, and the inspection and repair times for each of the plurality of structures are shifted.

[Planning with inspection method / repair method and budget]
FIG. 15 shows an example of creating a plan in consideration of the inspection method / repair method and budget. The structures # 1, # 2, and # 3 have different deterioration states, and an inspection method and a repair method corresponding to each deterioration state are selected. For example, for structure # 1, progress is made to “deterioration level 2” in 2017, inspection of “method A” is selected as the inspection method, progresses to “deterioration level 3” in 2019, and “ Repair of “Method A” is selected. For structure # 2, progress was made to “deterioration level 2” in 2018, inspection of “method B” was selected as the inspection method, progressed to “deterioration level 3” in 2020, and “construction method B” was repaired. "Repair" is selected. For structure # 3, progress was made to “deterioration level 2” in 2017, inspection of “method C” was selected as the inspection method, progressed to “deterioration level 3” in 2019, and “construction method C” was repaired. "Repair" is selected.

  Each fiscal year has a budget upper limit. The inspection / repair plan creation visualization unit 14 calculates the cost value required for inspection and repair for each fiscal year in the above plan (first plan), and whether the cost value for each fiscal year exceeds the budget upper limit. Check if. If the cost value for each year does not exceed the budget upper limit value, the inspection / repair plan creation visualization unit 14 establishes the plan (first plan). When the cost value for each year exceeds the upper limit of the budget, the inspection / repair plan creation visualization unit 14 reviews the plan (first plan) and reviews another plan (second plan). create. For example, in FY2019, there are repair items for structure # 1 and repair items for structure # 3 at the same time. Suppose that the cost value for FY2019 exceeds the budget upper limit for FY2019. Therefore, the inspection / repair plan creation visualization unit 14 sets either the repair item of the structure # 1 or the repair item of the structure # 3 as the cost value of the fiscal year in order to reduce the cost value of FY2019 within the upper limit of the budget. Correction is made so as to shift to another fiscal year (for example, fiscal 2018) when there is room. For example, the repair item for structure # 1 is shifted to FY2018, and the total cost value of the inspection item for structure # 2 and the repair item for structure # 1 in FY2018 does not exceed the budget upper limit for FY2018. In such a case, the amendment is deemed to be established. As described above, a suitable plan considering the inspection method / repair method and budget is created.
