Description

  The present invention relates to a technique for managing a structure such as a bridge, and more specifically to a management technique using a three-dimensional model of the structure.

  It has been pointed out that the construction infrastructure (hereinafter referred to as “construction infrastructure”) that has been intensively developed during the period of high economic growth has already undergone considerable deterioration. In 2014, the “Proposal for Full Implementation of Road Aging Measures (Social Capital Development Council)” was compiled, giving examples of the Choshi Tunnel in 2012, “In the near future, human life and society such as the collapse of bridges” It will lead to a fatal situation related to the equipment, "he urged and emphasized the importance of maintaining construction infrastructure.

  Against this backdrop, the government promulgated a ministerial ordinance to revise a part of the Road Law Enforcement Regulations, and showed a specific method for inspecting construction infrastructure, points of major deformations, pictures of judgment cases, etc. The inspection procedure is formulated. This periodic inspection procedure covers bridges with a length of 2.0 m or more, which is said to be about 700,000 bridges. The first inspection is performed within 2 years after the start of service, and then the periodic inspection is performed once every 5 years thereafter. I am going to do that. In addition, distant visual observation using binoculars or the like is not permitted even on the lower surface of the bridge, and as a general rule, inspection by close visual inspection with the naked eye must be performed.

  However, construction infrastructure is often a relatively large structure, so it is not so easy to inspect it with close-in visual inspection. In particular, in order to inspect a complicated structure composed of a wide variety of members such as bridges, considerable labor and time are required, and considerable costs must be prepared accordingly.

  Therefore, Patent Document 1 proposes a technique for selecting members to be preferentially inspected by paying attention to the degree of influence and the damage speed, instead of inspecting all the members equally.

JP2011-080211A

  Patent Document 1 is a technique for extracting members to be inspected in particular. However, in the case of construction infrastructure, the present situation is that all (or most) constituent members are inspected. Once construction infrastructure is destroyed, not only is the social economy damaged, but many people can be damaged by accidents. For this reason, the construction infrastructure manager wants to check most of the members and check for any abnormalities.

  As a result of the inspection, if an abnormality is confirmed in the member, repair or reinforcement is performed in consideration of the degree of abnormality or the influence on the entire structure. Then, history information such as inspection results and repair results is recorded and used for future inspection to repair. In other words, inspecting the majority of the members that make up the structure means that there is a possibility of repairs (possibly) on many members, and there are a wide variety of structures that make up the structure. This means that it is necessary to record and store history information for each number of members, resulting in a significant amount of labor and time, and the associated considerable costs.

  In order to reduce the labor and time required for a series of management practices such as actual inspection work, repair / reinforcement, and recording of history information from the inspection plan, it is necessary to improve the efficiency of the actual work. Therefore, it is conceivable to use CIM (Construction Information Modeling) that has been proposed in recent years as a method for managing the structure. CIM uses a three-dimensional model and ICT (Information and Communication Technology) to consistently share information at each stage (planning, design, construction, management) in the construction production system. This will improve the efficiency of a series of construction production systems. The effects of introducing CIM are expected to be improved infrastructure maintenance and management in addition to business efficiency and economic effects such as a significant reduction in mistakes and rework, reduction of simple work, and shortening of processes.

  However, because CIM is a relatively new concept, the actual situation is that it has not yet been practically used as a practical method in the construction technology field, particularly in the civil engineering field. For this reason, no technique utilizing CIM has been proposed for the method of managing structures.

  An object of the present invention is to solve the problems of the prior art, that is, a structure management support system and a structure management method capable of supporting efficient management of structures by utilizing CIM. Is to provide.

  The invention of the present application is that a 3D model created for each member or material and its attribute information are used together, and that a moving image that artificially travels the inspection route is created and used based on this 3D model. The invention was made based on an idea not found in the past.

  The structure management support system of the present invention uses a three-dimensional model of a structure, and is a system provided with member information storage means and member designation means. The member information storage means is means for storing a member three-dimensional model and member attribute information. The member three-dimensional model has position information and is created for each of a plurality of members constituting the structure, and one member attribute information is information including at least inspection information and repair information. The member specifying means is means for specifying a desired member among the members displayed on the display means. When a member is designated by the member designation means, the member three-dimensional model and member attribute information associated with the member are read from the member information storage means and displayed on the display means.

  The structure management support system of the present invention may further include a material information storage unit and a material designation unit. The material information storage means is means for storing a material three-dimensional model (created for each material constituting the member) and material attribute information (including inspection information, repair information, and material property information), and the material designation means is , Means for designating a desired material from the members displayed on the display means. When a material is designated by the material designation means, the material three-dimensional model and material attribute information associated with the material are read from the material information storage means and displayed on the display means.

  The structure management support system of the present invention may further include a form creation means. The form creation means extracts the member attribute information from the member information storage means based on the search condition, extracts the material attribute information from the material information storage means, and displays the extracted member attribute information and material attribute information in a list format. This is a means for creating a displayed form.

  The structure management support system according to the present invention may further include a route specifying unit, a moving image creating unit, and a moving image reproducing unit. The route designation means is means for designating a desired movement route. The moving image creating means is a means for creating a pseudo moving moving image (moving image viewed from the moving route in the order of the moving route) based on the moving route specified by the route specifying means, and the moving image reproducing means Is a means for playing back the pseudo-moving moving image. In this case, it is possible to provide a moving image playback means having a function of creating a “pseudo-moving moving image having absolute coordinates” by assigning absolute coordinates to the screen constituting the pseudo-moving moving image, and the input position coordinates Based on the above, it is also possible to use a moving image reproducing means for reproducing from a start screen extracted from “pseudo-moving moving image having absolute coordinates”.

  The structure management method of the present invention is a structure management method using a structure management support system, and includes a moving process, a member designating process, a member confirmation process, and a recording process. The structure management support system stores a member information storage for storing a member three-dimensional model having position information (created for each of a plurality of members constituting the structure) and member attribute information (including inspection information and repair information). Have means. In the moving process, the vehicle moves to a management point required (inspected point or required repair point) displayed on the display means of the structure management support system. In the member designation step, a desired member is designated from among the members at the management points required displayed on the display means, and in the member confirmation step, the member three-dimensional model and member attribute information displayed on the display means are confirmed. The member three-dimensional model and member attribute information displayed here are the member three-dimensional model and member attribute information of the member specified in the member specifying step, and are read from the member information storage means. In the recording step, the member designated in the member designation step is inspected or repaired, and the result is associated with the member and stored in the member information storage means.

  The structure management method of the present invention can be a method further including a route planning step. In the route planning process, a desired moving route is specified, and the simulated moving moving image (moving state viewed from the moving route in the order of the moving route) is reproduced and confirmed. Plan travel routes.

  The structure management method of the present invention is a method of moving the moving path while reproducing the simulated moving moving image at substantially the same speed as the walking speed in the moving process, and confirming the current position while viewing the simulated moving moving image. You can also.

The structure management support system and the structure management method of the present invention have the following effects.
(1) Since the concept of CIM is adopted, information is shared at each stage in a series of management practices. For this reason, it is possible to greatly reduce mistakes in information takeover between stages and the rework associated therewith.
(2) Since the three-dimensional model and its attribute information are created for each member or material, the three-dimensional shape of the member or material and information unique to the member or material can be easily confirmed.
(3) Since it is a mechanism that holds attribute information for each member or material, the necessary information is registered for each member or material on the spot where the inspection work is performed or on the spot where the repair work is performed. be able to. As a result, it is possible to reduce the trouble of post-processing at an office or the like and to prevent errors due to transcription.
(4) An appropriate inspection route can be selected in advance by using the pseudo moving moving image. Thereby, reworking of the inspection work can be prevented and the efficiency of the inspection work can be improved.
(5) At the time of inspection, the current position of the inspector can be confirmed by reproducing the simulated moving moving image in accordance with the walking speed of the inspector. As a result, it is possible to prevent reworking of the inspection work and increase the efficiency of the inspection work.

  An example of an embodiment of a structure management support system and a structure management method according to the present invention will be described with reference to the drawings.

1. Definitions In describing examples of embodiments of the present invention, definitions of terms used here are given first.

(Parts and materials)
A “member” is an element constituting a structure. For example, when the structure is a bridge, floor slabs, main girders, cross girders, anti-tilt structures, etc. can be mentioned as members. One “material” is an element constituting a member. For example, in the case of a main girder as a member of a bridge, examples of the material include an upper flange, a lower flange, and a web (web). Therefore, one structure may include a plurality of members, and one member may include a plurality of materials.

(3D model)
A “three-dimensional model” is a three-dimensional model created in a virtual space of a computer. Usually, the difference between two dimensions and three dimensions is the presence or absence of a value in the height direction (Z axis). Conventionally, when a structure is represented three-dimensionally, it has been performed by using two-dimensional drawings such as an elevation, a plan view, and a side view in combination, but a three-dimensional model can be represented three-dimensionally by itself. . In order to display a three-dimensional model, it is common to use a two-dimensional display means such as a display, but the state viewed from various angles can be displayed by a user operation.

(3D member model and 3D material model)
Here, for convenience, the three-dimensional model of the member is referred to as “member three-dimensional model” and the three-dimensional model of material is referred to as “material three-dimensional model”. The member three-dimensional model has relative position information in the structure. In other words, since the member three-dimensional model has position information, it is possible to express at which position of the structure the member is located. Similarly, the material three-dimensional model also has relative position information within the member. Therefore, a member 3D model can be formed by a plurality of material 3D models, and a 3D model of a structure can be formed by a plurality of member 3D models. The relative position information of the members may be coordinates (arbitrary coordinates) in a so-called arbitrary coordinate system (local coordinate system), but of course, the coordinates (absolute coordinates) of a so-called absolute coordinate system such as the world geodetic system are used. You can also.

(Attribute information)
“Attribute information” is information that represents the characteristics of an object. For example, the attribute information of the structure includes a name, a type, a construction time, a construction person, and the like. Here, for convenience, the member attribute information is referred to as “member attribute information”, and the material attribute information is referred to as “material attribute information”. In addition, the member attribute information includes a past inspection record (hereinafter referred to as “inspection information”) and a past repair and reinforcement record (hereinafter collectively referred to as “repair information”). In addition, the name of the member, information when the member is manufactured, member strength, material information constituting the member, and the like can also be included. The material attribute information includes inspection information, repair information, material property information such as material strength, elastic modulus, temperature characteristics, etc. In addition, the name of the material and the process when manufacturing the member (welding, attachment, etc.) , Information when purchasing the material can also be included. The inspection information can be stored as an inspection history record, and the repair information can be stored as a repair history record in a document file format, an image file format, or a drawing file format.

(Component information and material information)
As shown in FIG. 1, “member information” is information obtained by combining “member three-dimensional model” and “member attribute information” relating to a member. Similarly, “material information” is information obtained by combining “material three-dimensional model” and “material attribute information” relating to a material, as shown in FIG. That is, the member information can be constituted by a plurality of material information as shown in FIG. 2, and the structure information can be constituted by a plurality of member information as shown in FIG. The member three-dimensional model and member attribute information (or material three-dimensional model and material attribute information) may be stored in different storage means (or database). In this case, the member three-dimensional model is stored for each member. And member attribute information (material three-dimensional model and material attribute information) may be stored in association with each other. Similarly, member information (specifically, member attribute information) and material information included in the member information may be stored in different storage means (or database). In this case, the member information and the material information are associated with each other. To remember.

2. Structure Management Support System Next, the structure management support system of the present invention will be described with reference to the drawings. FIG. 3 is a block diagram illustrating a main configuration of the structure management support system 100. Each means shown in this figure executes a program in which the contents performed by each means are described, and can be manufactured as a dedicated one, or a general-purpose computer device can be used. This computer apparatus can be configured by a personal computer (PC), a tablet terminal such as iPad (registered trademark), a smartphone, or a PDA (Personal Data Assistance). The computer device includes a processor such as a CPU and a memory such as a ROM and a RAM, and further includes an input unit such as a mouse and a keyboard and a display (display unit). In addition, although it inputs from devices, such as a mouse | mouth and a keyboard, if it is a general PC, it is often input by operation (a tap, pinch in / out, a slide, etc.) using a touch panel with a tablet type terminal or a smart phone. Hereinafter, each means constituting the structure management support system 100 will be described in detail.

(Member information storage means)
The member information storage means 101 is means for storing member information that is a combination of a member three-dimensional model and member attribute information, and can be constructed in a database server, for example. The member information storage unit 101 can be placed in a local network (LAN: Local Area Network), or of course, can be a cloud server stored via the Internet. Member information is memorize | stored for every structure, and the member information of a some structure part can also be memorize | stored. With such a configuration, for example, when a desired structure is designated by a user operation, a member information related to the structure can be displayed.

(Display means)
The display means 102 is a means for displaying a member three-dimensional model and member attribute information, or a material three-dimensional model and material attribute information. For example, a display can be used.

(Member designation means)
The member designating unit 103 is a unit that designates a desired member of the structure. For example, a three-dimensional model of the entire structure (or a part) can be displayed on the display means 102, and a desired member can be designated (for example, clicked) from the display.

(Material information storage means)
The material information storage unit 104 is a unit that stores material information that is a combination of a material three-dimensional model and material attribute information, and can be constructed in, for example, a database server. Since the material information is stored for each member and normally a plurality of member information is stored, for example, when a desired member is designated by a user operation, the material information related to the member can be displayed. Note that the member information storage unit 101 and the material information storage unit 104 may be constructed in different database servers, or may be constructed using one database server. Similarly to the member information storage unit 101, the material information storage unit 104 can be placed on a local network, or of course, can be a cloud server stored via the Internet.

(Material designation means)
The material designation means 105 is a means for designating a desired material among the members. For example, a mechanism in which a member three-dimensional model is displayed on the display unit 102 and a desired material is designated (for example, clicked) from the display can be employed.

(Video creation means)
The moving image creating means 106 is a means for creating a “pseudo moving moving image”. Here, the pseudo-moving moving image will be described. Usually, in the case of visual inspection, a plan is made such as to what range the day is carried out or on what route (route) to move. Of these, the planning of a moving route (hereinafter referred to as “moving route”) has not been carried out so carefully in the past, although it is directly related to the efficiency of inspection work. This is because the actual situation cannot be grasped in advance even if it is examined on a two-dimensional drawing (plan view or the like). For example, even if the shortest movement route is planned on the plan view, there are places where people cannot actually pass through, there are parts that cannot be seen from the movement route, and it may not proceed as expected. . For this reason, it has been difficult to find a value for carefully planning a moving route.

  On the other hand, if the movement route is planned with a three-dimensional model instead of a two-dimensional drawing, the actual situation can be grasped in detail, and as a result, efficient inspection work can be performed, which is extremely useful. Become. Therefore, the structure management support system 100 of the present invention provides a pseudo moving moving image created based on a three-dimensional model. FIG. 4 is a model diagram for explaining the pseudo-moving moving image, and shows a situation in which the situation (scenery) of the site viewed by the inspector is sequentially changed (three screens are changed from the top in the figure). As shown in this figure, the pseudo-moving moving image is a moving image in which the situation that the inspector sees (will be) when moving on the designated route is generated based on the three-dimensional data of the member. This is a pseudo (virtual) moving image, which is a so-called CG (Computer Graphics) moving image. More specifically, visual dimensions such as eye height when an inspector stands at an arbitrary point on the route, a line-of-sight direction based on the route direction, and a visual field are set, and the three-dimensional members around the visual item and its surroundings are set. A pseudo-moving moving image is created by creating a CG based on the model and making a transition with the movement of the inspector.

  In creating the simulated moving moving image, first, the moving route is specified by the route specifying means 107. At this time, when a visual inspection passage (hereinafter referred to as “inspection passage”) is provided as a member of the structure, the inspection passage may be designated. As a specific method of designating the movement route, a plan view of the inspection passage is displayed on the display means 102, and a desired movement route is designated from the display (for example, a passage point is clicked). It can be. The designated movement route is stored as a trajectory set in the local coordinate system (or absolute coordinate system).

  When the user designates a movement route by operating the route designation unit 107, the moving image creating unit 106 creates a pseudo moving moving image. Then, triggered by the user operation, the moving image reproducing means 109 read from the moving image storage means 108 reproduces the pseudo moving moving image, and the state is displayed on the display means 102. For example, the most appropriate movement route (that is, the actual inspection route) can be selected by designating several movement routes and reproducing each simulated moving moving image. Note that the pseudo moving moving image created by the moving image creating unit 106 is stored in the moving image storage unit 108. The moving image storage unit 108, the member information storage unit 101, and the material information storage unit 104 may be constructed in different database servers, or may be constructed using one database server. Like the other storage means, the moving image storage means 108 can be placed on a local network, or of course, can be a cloud server that saves via the Internet.

  The moving image reproducing means 109 may be configured to create “a pseudo moving moving image having absolute coordinates (plane coordinates)”. Specifically, using the function of the moving image playback means 109, absolute coordinates (plane coordinates) are assigned to the screen (one frame) constituting the pseudo moving video, and a pseudo moving video having absolute coordinates is created. To do. Of course, absolute coordinates may be given to all screens, or absolute coordinates may be given only to representative screens (for example, screens extracted every several frames). When each member (specifically, a member three-dimensional model) has absolute coordinates, the absolute coordinates can be given to the screen using the absolute coordinates of the members. For example, representative coordinates of members included in the screen (preset for each member) may be assigned to the screen, or a viewpoint corresponding to the screen (point on the inspection path) may be assigned to the screen.

  When the “pseudo-moving moving image having absolute coordinates (plane coordinates)” is created by the moving image reproducing unit 109, the moving image reproducing unit 109 reproduces the pseudo moving images from the screen corresponding to the input absolute coordinates (plane coordinates). It should be a specification. For example, the current location (absolute coordinates) of the inspector is input, and the video reproduction means 109 extracts the (closest) screen corresponding to the current location coordinates, and the pseudo-moving video is referred to from this screen (hereinafter referred to as “start screen”). Is started (started).

(Member information input means)
The member information input unit 110 is a unit that newly inputs member attribute information for a member and edits already registered member attribute information. Use the device such as a keyboard or mouse to input / edit text on the member specified by the member specifying means 103, attach an inspection history record or repair history record document file, etc. Necessary member attribute information is input and edited using various methods. Of course, the member attribute information input / edited by the member information input means 110 is stored in the member information storage means 101 as that of the corresponding member.

(Material information input means)
The material information input unit 111 is a unit that newly inputs material attribute information for a material and edits already registered material attribute information. For materials specified by the material specifying means 105, text can be input / edited using a device such as a keyboard or a mouse, an inspection history record or a repair history record document file is attached, etc. Necessary material attribute information is input and edited by using various methods. Of course, the material attribute information input / edited by the material information input unit 111 is stored in the material information storage unit 104 as that of the corresponding material.

(Form creation means)
The form creation unit 112 reads the member attribute information from the member information storage unit 101 and reads the material attribute information from the material information storage unit 104 based on the search condition, and creates a form of the member attribute information and the material attribute information. It is. Of course, the created form can also be output by the display means 102, a printer, or the like. Specifically, a desired condition is input, and member attribute information and material attribute information that match the condition (having the condition as attribute information) are extracted from the member information storage unit 101 and the material information storage unit 104, A form that represents this in a list format is created. For example, in FIG. 5, as a result of inputting a search condition of “reinforcement of the contact plate”, the upper flange of the member A and the lower flange of the member C are extracted as the material subjected to the reinforcement of the contact plate, and these are used as a form It is output.

(Example of use)
An example of using the structure management support system 100 of the present invention will be described with reference to FIG. Note that the structure management support system 100 can be used for various types of structures, but here, for convenience, an example in which the structure is a bridge will be described.

  The inspector carries, for example, a tablet PC in which the structure management support system 100 is stored, heads for the site, and performs a visual inspection on a predetermined member. In visual inspection, member attribute information (such as an inspection history record and a repair history record) of the member or material attribute information of a material constituting the member can be confirmed. Specifically, as shown in FIG. 6A, a three-dimensional model of the entire structure (or part) is displayed on the display means 102 provided in the tablet PC, and the target member is designated by the member designation means 103. To do. However, in a relatively large structure such as a bridge, it is difficult to pinpoint a desired member. Therefore, a divided block obtained by dividing the bridge into a plurality of blocks may be specified, and a desired member may be specified from the divided blocks displayed on the display unit 102. At this time, as shown in FIG. 6B, the divided blocks can be displayed as a plan view, or can be displayed as a three-dimensional model. Since the divided blocks are also composed of a plurality of member three-dimensional models, they can be displayed as a three-dimensional model.

  When the inspector designates a target member (for example, a member that has been repaired in the past) by the member designation means 103 and selects the display of the member attribute information, as shown in FIG. Member attribute information such as a history record or repair drawing is displayed on the display means 102 of the tablet PC. In addition, the result of the inspection by the inspector can be input on the spot using the member information input means 110. Furthermore, it is good also as a mechanism which transmits the member attribute information input with the member information input means 110 to the distant place (for example, an office or a cloud server) using the transmission / reception means which tablet PC comprises.

  When the inspector designates a target member by the member designation means 103 and selects display of the member three-dimensional model, the member three-dimensional model of the member is displayed on the display means 102 of the tablet PC as shown in FIG. Is displayed. When the material constituting the member is designated by the material designation means 105 in the state in which the member three-dimensional model is displayed and display of the member three-dimensional model is selected, the material three-dimensional model of the designated material is displayed on the tablet PC. When displayed on the means 102 and the display of material attribute information is selected, material attribute information such as an inspection history record, a repair history record, or a repair drawing as shown in FIG. 6C is displayed. Further, the material attribute information can be input on the spot using the material information input unit 111. Furthermore, it is good also as a mechanism which transmits the material attribute information input with the material information input means 111 to a distant place (for example, an office or a cloud server) using the transmission / reception means which tablet PC comprises.

3. Structure Management Method Next, the structure management method of the present invention will be described with reference to FIG. Note that the structure management method of the present invention is a method using the structure management support system 100 described so far, and therefore, a description overlapping the contents described in the structure management support system 100 is avoided, and the structure management method is avoided. Only the contents specific to will be explained. That is, the contents not described here are the same as those described in the structure management support system 100.

  FIG. 7 is a flowchart showing the flow of the main steps of the structure management method of the present invention, and the structure management method will be described below with reference to this figure. First, a movement route is planned as a movement route when visual inspection or repair is performed in advance (Step 100). At this time, if it is to be inspected, confirm the places that should be inspected in the past, such as places that should be noted in past inspections or places that have been repaired in the past (hereinafter referred to as “required inspection points”). And then plan the travel route. Alternatively, in the case of repair, the travel route is planned after confirming the location to be repaired (hereinafter referred to as “repair required location”).

  In planning a movement route, it is also possible to determine an appropriate movement route by confirming a pseudo movement moving image. Specifically, a plurality of candidate movement paths that pass through a point requiring inspection or a point requiring repair (hereinafter collectively referred to as a “required management point”) are designated by the route designation means 107, and based on the respective movement routes. The pseudo-moving moving image created by the moving image creating means 106 is reproduced and confirmed by the moving image reproducing means 109. Then, the most appropriate travel route is determined as the actual travel route. As described above, when an inspection passage is provided as a member of the structure, a movement route may be designated from the inspection passage.

  When the inspection plan including the movement route is established, the inspector carries, for example, the tablet PC storing the structure management support system 100, heads for the site, and further plans the planned movement to the necessary management point confirmed in advance. It moves along the route (Step 200).

  By the way, in the case of a structure such as a bridge having a relatively large scale, once entering the structure (for example, an inspection passage), it may be impossible to accurately grasp where the inspector himself is. Therefore, in some cases, a mark such as a distance marker, a member number (for example, a crossbeam number), or a plan view showing the current location is written on the site (structure). However, such marks and drawings may disappear over time, and there are even structures that do not have such marks in the first place.

  In such a case, it is good to confirm the present location of the inspector by confirming the pseudo moving video. Specifically, when the inspector moves, the simulated moving moving image created in the route planning step (Step 100) is reproduced at a walking speed (about 30 to 80 m per minute). Of course, when the inspector stops, the moving image reproducing means 109 is operated to stop (pause) the pseudo moving image. Then, the pseudo moving image is confirmed on the display means 102 of the tablet PC, and the surrounding situation is also confirmed. If the situation of the display unit 102 and the surrounding situation substantially coincide with each other, the current position of the inspector can be grasped from the member (having position information) shown on the display unit 102. Alternatively, when the situation of the display means 102 and the surrounding situation are different, the video playback means 109 is operated to search for a screen that substantially matches the surrounding situation by fast-forwarding or rewinding the pseudo-moving moving picture, and displayed on the screen. The current position of the inspector can be grasped from the member.

  When the “pseudo-moving moving image having absolute coordinates” is created by the moving image reproducing means 109 and the specification is such that the moving image reproducing means 109 starts reproduction corresponding to the input absolute coordinates, the pseudo moving moving image is as follows: Can also be played. An inspector performs positioning using, for example, a global positioning satellite system (GNSS) by positioning means 113 (FIG. 3) provided in the tablet PC, and acquires his current position coordinates (planar coordinates). Receiving the current location coordinates, the moving image reproduction means 109 searches for a screen closest to the current location coordinates among the screens constituting the pseudo moving image. Then, the pseudo moving image is started using the screen as a start screen. It is particularly effective to start the simulated moving video from the current location of the inspector when playing the simulated moving video from the middle of the movement route (that is, during the movement) or when the simulated moving video is completely different from the surrounding situation. It is.

  When moving to the management required location, the inspector designates a member included in the management required location (Step 300) and confirms the member information (Step 400). Specifically, as shown in FIG. 6A, a three-dimensional model of the entire structure (or a part) is displayed on the display means 102 provided in the tablet PC, a divided block is designated, and the displayed divided portion is displayed. The target member is designated by the designation means 103 from the block. Then, member attribute information such as a member three-dimensional model of the designated member, inspection history record, repair history record, or repair drawing is displayed on the display means 102 of the tablet PC. At this time, a material three-dimensional model of material constituting the member and material attribute information may be displayed on the display unit 102.

  When the information on the member or the member and the material is confirmed, the member is actually inspected or repaired, and the inspection result (inspection information) and the repair result (repair information) are recorded (Step 500). Specifically, inspection information and repair information are input as member attribute information and material attribute information by the member information input unit 110 and the material information input unit 111 and stored in the member information storage unit 101 and the material information storage unit 104. At this time, the member attribute information input by the member information input unit 110 can be configured to be transmitted to a distant place (for example, an office or a cloud server) using the transmission / reception unit included in the tablet PC. As described above.

  The structure management support system and the structure management method of the present invention are used not only for civil engineering structures such as bridges, dams, tunnels and large boxes, but also for building structures such as buildings (especially the back space such as ceilings) and steel towers. be able to. According to the present invention, it is possible to grasp the deterioration state of a structure in service, and as a result, repair and reinforcement measures according to the deterioration state are possible. As a result, it can be used industrially considering that it leads to a long life of an existing structure. It can be said that the invention can be expected to make a great contribution not only to society.
