(First embodiment)
FIG. 1 is a diagram for explaining an overview of an information processing system 1 of this embodiment.
The information processing system 1 collects and manages measurement data or imaging data of various inspection devices 40 that inspect concrete structures. The information processing system 1 includes various inspection devices 40, a server device (indicated as "server" in the figure) 10, a terminal device 30 (in FIG. 1, a notebook computer 30a and a tablet terminal 30b are exemplified), and an inspection system. It has a storage device 20 that stores measurement data and imaging data received from the device. The server device 10 and the storage device 20 are constructed on a so-called cloud 7. Therefore, the server device 10 and the storage device 20 are connected to the terminal device 30 and the inspection device 40 via a communication network. At least a portion of the communication network may be wireless.

Concrete structures need to be regularly inspected, investigated, or diagnosed to determine whether or not repairs are necessary and to review repair plans. Furthermore, damage and deterioration of concrete structures include those that appear externally, such as cracks, and those that progress internally, which cannot be seen from the outside, such as carbonation, cavitation, and corrosion of reinforcing steel. Inspection, investigation, or diagnosis of concrete structures is performed by measuring and imaging damage and deterioration of the concrete structure using various devices. By combining the results obtained using multiple types of devices in this way, it is possible to further improve the accuracy of inspection, investigation, or diagnosis of concrete structures.

Measurement and imaging data collected at the inspection site are aggregated in the server device 10. For example, the information may be temporarily imported into a terminal device 30 used by an operator such as a worker or a manager at the site and then transferred to the server device 10, or may be directly transmitted from the inspection device 40 to the server device 10. The data received by the server device 10 is stored and accumulated in the storage device 20. Although one server device 10 and one storage device 20 are shown in the figure, it may be composed of multiple computers and multiple storages. A plurality of users can connect to the cloud 7 via a communication network, and various services can be provided to each user.

Using images captured from a distance using an infrared camera, the condition of the exterior wall can also be detected from the temperature difference on the concrete surface. The position of reinforcing bars inside concrete, detection of foreign objects, measurement of cover thickness, etc. are performed using a reinforcing bar detection device such as an electromagnetic wave radar or an electromagnetic induction device. Using an ultrasonic probe, it is possible to detect the thickness of concrete plates and foreign objects, measure the depth of cracks, and diagnose deterioration. The corrosion status of reinforcing bars can be diagnosed using a self-potential measuring device or a polarization resistance device. A test hammer or the like may be used to diagnose the strength and deterioration of concrete.

The inspection result data 50 or the repair content data 54 may further include information that can identify the worker (worker ID, name, affiliation, organization name, etc.).

The display processing unit 102 displays the inspection result data 50 or repair content data 54 accumulated in such a data structure in association with a three-dimensional image.

FIG. 8 is a flowchart showing an example of the operation of the concrete structure management device 100. First, the display processing unit 102 displays a three-dimensional image of the concrete structure on the display device 74 of the terminal device 30 (step S101). Then, when the operator selects a certain location on the three-dimensional image, the reception unit 104 receives the selected location (step S103). Then, the reception unit 104 specifies the structure ID, area, or division ID corresponding to the selected position, and passes it to the display processing unit 102 (step S105).

Then, the display processing unit 102 reads information corresponding to the area or section from the management table 52, and determines which test information is stored from the test ID stored in the management table 52 (step S107). Then, the display processing unit 102 can include and display the test items whose test information is stored in the operation menu (step S109), and allow the operator to select the test items to be displayed. When the operator selects an inspection item from the operation menu, the reception unit 104 receives the inspection item (step S109), acquires the data ID of the inspection item that is associated with the area or division ID, and sends it to the display processing unit 102. Hand over. The display processing unit 102 reads the measurement value information associated with the data ID from the test result data 50 (step S111), and displays it in association with the corresponding area or section of the three-dimensional image (step S113). The operation menu may be displayed by right-clicking the mouse or by long-pressing the touch panel.

For example, if the measurement value information is image data from an infrared camera, the display processing unit 102 reads the image data from the storage device 20 and displays the image data in a superimposed manner at the position of the corresponding region or section of the three-dimensional image. Alternatively, if the measurement value information is text data, the display processing unit 102 opens a separate window near the area or section to display the text data, or displays a speech bubble from the position of the area or section, Text data may also be displayed therein.

In another example, the inspection item may be selected from the menu first, and then the position of the structure may be selected. In that case, the display processing unit 102 refers to the management table 52, specifies the area or division ID of the structure in which the selected inspection item (inspection ID) is stored, and only the area or division can be selected. A three-dimensional image may also be displayed. For example, the operator can be made aware that a selectable region or section is selectable by displaying the region or section in a different color or highlighting it. By not changing the display of a region or section for which there is no test result information for the relevant test item, the operator can recognize that there is no test result information for that region or section. The color change and highlight display may be performed when the mouse cursor is superimposed on the region or section by an operator operation (so-called mouse-over operation).

Further, the receiving unit 104 may receive multiple selections of inspection items, or multiple selections of regions or sections. The display processing unit 102 may display information on all test items for the selected region or section. The operation menu may be displayed using a general GUI (Graphical User Interface) such as a menu list, a pull-down menu, a radio button, a check box, or a drum roll type UI (User Interface).

As explained above, in this embodiment, when the reception unit 104 receives an operation to select at least a part of the concrete structure in the three-dimensional image displayed on the screen, the display processing unit 102 displays the inspection results of the selected part. and information including at least one of the repair contents is displayed on the screen in association with the part. In this way, when the operator selects and operates a location on which the concrete structure is displayed as a three-dimensional model, the information for that location will be displayed. You can view the information. Therefore, according to this embodiment, it is possible for the manager to easily understand the inspection results and repair details of the concrete structure.

(Second embodiment)
This embodiment is the same as the above embodiment except that it has a configuration for displaying history information of inspection result data 50 and repair content data 54. Since the concrete structure management device 100 of this embodiment has the same configuration as the concrete structure management device 100 of the above embodiment shown in FIG. 3, it will be explained using FIG. 3. The configuration of the concrete structure management device 100 of this embodiment can be combined with the configurations of other embodiments within a consistent range.

The display processing unit 102 accesses the storage device 20 that stores history information of at least one of the inspection results and repair details of the concrete structure, and displays the history information of the selected part of the concrete structure as the selected part. Associate it and display it on the screen.

Further, the display processing unit 102 changes the display format for each predetermined region of the structure based on the history information and according to the storage period of information including inspection results and repair details. The accumulation period indicates, for example, how many years' worth of data (or amount) has been accumulated (1 year, 2 years, 5 years, 10 years, etc.), or indicates the amount of data accumulated during the inspection period. Additionally, the information may be information indicating the progress status of the test (test not yet performed, test in progress, test completed, etc.). Methods for changing the display format are exemplified below, but are not limited to these.
(1) A different display color or a different pattern is superimposed and displayed in the area for each accumulation period.
(2) Highlight areas where the accumulation period is greater than or less than the standard.
(3) A different predetermined mark is superimposed and displayed within the area or near the area for each accumulation period.

FIG. 9 is a diagram illustrating an example of the data structure of the accumulated information 56 that stores information indicating the accumulation period of history information for each region of the structure. For example, the accumulated information 56 stores flags indicating the presence or absence of history information for each year in association with a structure ID and an area or division ID.

FIG. 10 is a diagram for explaining a change in the display form of the screen 200 according to the storage period of history information. In the example in Figure 10(a), the two walls (corresponding to areas r0201 and r0202) have accumulated one year's worth of history information only for 2018, so the two walls are displayed in the same color. has been done. In the example in Figure 10(b), of the two walls, area r0211, which corresponds to the wall on one side, has accumulated history information for two years, 2017 and 2018, and corresponds to the wall on the other side. Since the area r0212 stores one year's worth of history information only for 2018, the two walls are displayed in different colors.

In this way, the display processing unit 102 can refer to the accumulated information 56 and change the display form for each region or section.

In another example, the display processing unit 102 may change the display format depending on the progress status of the test (not yet performed, currently being tested, completed, etc.) during the test period. The display processing unit 102 refers to the management table 52 and performs the inspection based on conditions such as date and time information, inspection items, and the number of data of the data corresponding to the area or section of the three-dimensional image displayed on the screen 200. It is determined whether the inspection has not been performed, is being inspected, or has been completed. The judgment conditions can be obtained by the operator inputting test result information. The test result information may include the test period, the area or section to be tested, the test items, the type of data that needs to be measured, the number of data, and the like. Based on the determination result, the display processing unit 102 changes the display form for each area.

As explained above, in this embodiment, the history information of the portion selected by the display processing unit 102 is displayed on the screen in association with the selected portion. Further, the display processing unit 102 changes the display form for each predetermined area of the structure according to the storage period of the history information. As described above, according to the present embodiment, it is possible for the administrator to easily understand the inspection results and repair contents of the concrete structure, and furthermore, it is possible to view historical information including past information of the concrete structure, and the historical information Since the display format is changed for each region according to the storage period, the operator can intuitively know how much data is stored in which region. Furthermore, according to the present embodiment, the display form can be changed for each area according to the progress of the inspection, so the operator can know the progress of the inspection for each area at a glance.

(Third embodiment)
FIG. 11 is a functional block diagram logically showing the configuration of the concrete structure management device 100 of this embodiment. The concrete structure management device 100 of this embodiment is similar to the above embodiment except that it has a configuration that limits data displayed on the screen according to the access authority of the operator. Further, the configuration of the concrete structure management device 100 of this embodiment can be combined with the configurations of other embodiments within a consistent range. The concrete structure management device 100 includes the same display processing section 102 and reception section 104 as in FIG. 3, and further includes an authority identification section 110.

The terminal device 30 can be used by, for example, a worker who performs inspection and repair work at the site, a manager who supervises the work, and a manager of the concrete structure to which work is requested. The information required differs depending on the position of each person, even if they are involved in work involving objects. Further, the information stored in the storage device 20 may include confidential information, and it is necessary to prevent such information from being carelessly leaked to the outside. Therefore, in this embodiment, by including the authority specifying section 110, data displayed on the screen is restricted according to the access authority of the operator.

The authority identification unit 110 identifies the access authority of the operator. The display processing unit 102 limits the data to be displayed on the screen 200 with respect to specific information according to the access authority.

The concrete structure management device 100 stores authentication information and access authority in association with each other in the storage device 20 as user information used when logging into this system. The authority identifying unit 110 can refer to the user information and identify the access authority from the authentication information input by the operator when logging in to use the services of the concrete structure management device 100.

Up to the embodiments described above, a configuration example in which inspection results and repair content information are stored in the storage device 20 has been described. In this embodiment, the storage device 20 may further include information at the time of construction of the structure as medical record information of the structure. Information at the time of construction may include, for example, structure design information, construction information, information on materials (cement, aggregate types and compositions, etc.), and the like.

There are at least two levels of access authority, and the scope of disclosure of specific information is set in advance for each level. The specific information that is restricted is, for example, information about the material of the structure (such as the type and composition of the material). The authority specifying unit 110 can limit the data to be displayed according to the set disclosure range.

The level of access authority depends on the classification of workers, supervisors, and managers, the content of work performed by the person, the type of employment of the worker, such as full-time employees and non-regular employees, and the type and target of the target concrete structure. It can be set according to at least one or a combination of laws and regulations applicable to the area and concrete structures.

The data restriction method by the display processing unit 102 is exemplified below, but is not limited thereto.
(1) The operation menu displays only operations related to information that can be disclosed.
(2) Inactivate the menu display for operations on information to which you do not have access authority.
(3) If information disclosure is requested for which the operator does not have access authority, a message will be displayed informing the operator that the operator does not have access authority and cannot display the data, and the data will not be displayed.

As explained above, in this embodiment, the scope of information disclosure is set for each access authority, the authority specifying unit 110 specifies the access authority of the operator, and the display processing unit 102 specifies the information according to the specified access authority. Regarding information, the data that can be displayed on the screen is restricted. As described above, according to the present embodiment, it is possible for the administrator to easily understand the inspection results and repair contents of the concrete structure, and the data to be displayed regarding specific information can be restricted according to the operator's access authority, so that the user can In addition to being able to appropriately provide necessary information, it is also possible to appropriately manage information that has disclosure restrictions.

(Fourth embodiment)
FIG. 12 is a functional block diagram logically showing the configuration of the concrete structure management device 100 of this embodiment. The concrete structure management device 100 of this embodiment is the same as any of the embodiments described above, except that it has a configuration that switches the data initially displayed on the screen 200 according to the relative position of the operator with respect to the concrete structure. . Further, the configuration of the concrete structure management device 100 of this embodiment can be combined with the configurations of other embodiments within a consistent range. The concrete structure management device 100 includes the same display processing section 102 and reception section 104 as in FIG. 3, and further includes a position information acquisition section 120.

The position information acquisition unit 120 acquires position information for specifying the relative position of the operator with respect to the concrete structure. The display processing unit 102 switches data to be displayed first based on the relative position.

Furthermore, the display processing unit 102 switches the data initially displayed on the screen 200 depending on whether the operator is outside the concrete structure or inside the concrete structure.

In this embodiment, the image of the concrete structure displayed on the screen 200 by the display processing unit 102 is displayed according to the relative position of the operator with respect to the concrete structure. As a premise, the operator carries the terminal device 30 to the location of the structure, and at that location displays a three-dimensional image of the concrete structure on the screen 200 of the terminal device 30, which is then provided by the concrete structure management device 100. Use the service.

The terminal device 30 is a portable terminal, for example, a tablet terminal 30b, a smartphone, a notebook computer 30a, etc., and in addition to the configuration described in FIG. 2, it further includes a position information acquisition means. The position information acquisition means is at least one of a GPS receiver, a mobile phone communication unit, and a wireless LAN communication unit. The location information acquisition unit 120 uses the location information acquisition means of the terminal device 30 to obtain, for example, GPS (or quasi-zenith satellite positioning system) location information, mobile phone base station location registration information, wireless LAN communication access point location. Acquire at least one piece of information. The location information acquisition unit 120 may acquire multiple types of location information and combine them to improve the accuracy of the location information.

Further, the terminal device 30 includes at least one of an acceleration sensor, a gyro sensor, a geomagnetic sensor, etc., and the position information acquisition unit 120 uses information from these sensors to display the display of the terminal device 30 held by the operator. further determine the direction of Then, assuming that the operator is facing a structure while holding the terminal device 30 in hand and looking at the display, the position information acquisition unit 120 further determines whether the operator is facing the structure based on the determined orientation of the display. Determine where you are standing and which direction you are facing. In this way, the position information acquisition unit 120 acquires the relative position of the operator with respect to the concrete structure.

The display processing unit 102 changes the location and orientation of the three-dimensional image displayed on the screen 200 based on the operator's relative position with respect to the concrete structure, that is, the position and orientation of the operator with respect to the structure. do. For example, when the operator is in a room in a building, the display processing unit 102 displays a three-dimensional image of the interior of the room on the screen 200. Then, the display processing unit 102 causes the screen 200 to display a location corresponding to the direction in which the operator points the terminal device 30 while holding the terminal device 30 in his hand and looking at the screen 200. That is, when the operator points the terminal device 30 toward the ceiling (the display surface faces downward), the display processing unit 102 causes the screen 200 to display a three-dimensional image of the ceiling of the living room. When the operator points the terminal device 30 toward the floor (the display surface faces upward), the display processing unit 102 causes the screen 200 to display a three-dimensional image of the floor of the living room.

The display processing unit 102 further specifies the area or division of the concrete structure from the position information, and selects data to be displayed first on the screen 200 based on the area or division. As described above, the corresponding information stored differs depending on the area or division. For example, inspection items and repair details differ depending on whether the structure is a ceiling, wall, or floor, and the type of information required by the worker also differs. Furthermore, since the type of structure being targeted changes depending on whether the operator is outside or inside the structure, the inspection items and repair details are different, and the type of information required by the operator also differs. different.

Therefore, the display processing unit 102 selects and displays the data to be displayed first based on the relative position between the concrete structure and the operator. Further, when the operator moves and the relative position with respect to the concrete structure changes, the display processing unit 102 switches the data to be displayed first based on the relative position of the movement destination.

Here, "first" means any of the following.
(1) From after displaying a three-dimensional image of a certain area or section of a concrete structure on the screen 200 to before accepting an operation from an operator for the area or section (2) From when an operator's operation for the area or section is received After first acceptance

In the latter case (2), the display processing unit 102 displays an external image of the concrete structure as a three-dimensional image based on the operator's relative position with respect to the concrete structure, and when the operator selects an area, the display processing unit 102 displays the inspection results or Display the repair data. At this time, the display processing unit 102 switches the data type of the inspection results or repair details to be displayed depending on the relative position of the operator.

In the former case (1), the display processing unit 102 selects the data type to be displayed for each area or section and displays it on the screen 200 first. The data display after the operator operates the area to display other information may be selectable by the operator's settings, for example. In other words, when the area is redisplayed on the screen 200 after leaving the screen 200, the display of the data changed by the operator's operation is maintained, or the data type set by default and initially displayed is changed. A configuration may be adopted in which it is possible to set whether to return to display.

FIG. 13 is a diagram showing an example of the data structure of the display data table 58. The display data table 58 in FIG. 13A stores position information and the type of data to be displayed first with the position information in association with each other. Here, the data type is, for example, at least one of an inspection ID indicating an inspection item, a repair item ID indicating repair contents, or data type information indicating a separately defined data type. The display processing unit 102 refers to the display data table 58, obtains the data type, for example, the inspection ID, corresponding to the position information acquired by the position information acquisition unit 120, and refers to the management table 52 to obtain the structure ID, area, etc. Alternatively, it is possible to obtain the classification ID, position information, and data ID corresponding to the test ID, read out the measurement value corresponding to the data ID from the test result data 50, and display it in a three-dimensional image.

FIG. 13(b) is a diagram showing another example of the data structure of the display data table 58. In this example, in addition to the position information, a structure ID and a region or division ID are also included. The display data table 58 may store data types corresponding to at least one of a structure ID, an area or division ID, and position information in association with each other. The display processing unit 102 can specify the data type corresponding to at least one of the structure ID, the area or division ID, and the position information from the display data table 58. For example, if the operator has previously input information for specifying a structure, the data type corresponding to the structure ID may be acquired and displayed first.

Furthermore, the display processing unit 102 may switch the data displayed on the screen depending on the display magnification.

The three-dimensional image of the concrete structure displayed on the screen 200 can be enlarged or reduced according to an operator's operation. The reception unit 104 receives, for example, a pinch-out or focus-in operation on the touch panel. The display processing unit 102 displays the three-dimensional image in an enlarged or reduced size according to an operator's operation.

The display processing unit 102 displays an image of the exterior of the concrete structure on the screen when the magnification is a first standard (small) or higher, and displays an image of the external appearance of the concrete structure on the screen when the magnification is a second standard (medium) or higher that is higher than the first standard. If the magnification is the third standard (large) or higher, which is higher than the second standard, an image showing damage to the concrete structure (such as cracks) will be displayed on the screen, and the concrete structure will be diagnosed. An image showing the analysis result is displayed on the screen 200.

FIG. 14 is a diagram showing another example of the data structure of the display data table 58. The display data table 58 stores a plurality of data types in association with at least one of a structure ID, an area or division ID, and position information. The plurality of data types are ranked (data types 1, 2, 3, etc.). For example, standard values of enlargement magnification (first standard, second standard, third standard) are associated with the rankings. The reference value of the magnification factor may be a range of magnification factors. In this example, three reference values are used, but the number of reference values is not limited to three, and may be less than three or more than three. Further, a standard for the reduction rate may be provided.

Here, for example, if the magnification is equal to or higher than the first standard (for example, equal magnification), data type 1, if the magnification is equal to or higher than the second standard (10x), data type 2, and if the magnification is the third standard. (10 to 100 times) can be defined as data type 3, etc.

In the display data table 58, data type 1 is image data of the external appearance of a concrete structure. Data type 2 is image data that represents data indicating damage to concrete structures, such as cracks, flaking, lifting, peeling, defects, discoloration, deformation, cavities, abrasion, rust, deflection, shearing, shrinkage, etc. Contains an image showing the state of the damage. Data type 3 is image data showing the diagnostic analysis results of concrete structures, such as images captured by an infrared camera, images showing the reinforcing steel corrosion diagnosis results by self-potential measurement, images showing the deterioration diagnosis results by ultrasonic exploration, Includes images showing the placement of reinforcing bars using electromagnetic radar.

The task of creating an image of data indicating damage of data type 2 may be created by a worker based on images showing various inspection results, or it may be created automatically by machine learning using artificial intelligence technology. may be done.

When an operator enlarges and displays a certain area on a three-dimensional image of a concrete structure, the displayed inspection results and repair content information are switched according to the enlargement magnification. For example, while displaying at the same magnification, the display processing unit 102 displays a three-dimensional image of the external appearance of the outer wall of the concrete structure on the screen 200, with the magnification factor being less than the second standard. Then, when the operator performs an enlargement operation and the enlargement magnification exceeds the second standard, the display processing unit 102 displays the image of the crack in the outer wall in a superimposed manner. Further, when the operator performs an enlargement operation and the enlargement magnification exceeds the third standard, the display processing unit 102 enlarges the three-dimensional image and switches the crack image to an image captured by the infrared camera of the area and displays it in a superimposed manner. .

Furthermore, when the third criterion is exceeded, the data type to be displayed may be selected according to the data type according to the area in combination with the display data table 58 of FIG. 13(b).

The type of data to be displayed according to the magnification and the order thereof may be set by the operator from a setting menu. The set data types and their ranks are stored in the display data table 58.

In addition, when another area is displayed on the screen 200 after the data type that is first displayed in a certain area is selected, the data type that is already displayed is inherited, or the data type that is newly displayed is selected. For the area, the data type may be switched to the first displayed data type based on the magnification or area. These selections may be set by the operator.

Furthermore, the display processing unit 102 sets the damage level of the concrete structure to be displayed on the screen 200 according to the enlargement factor. Here, the damage level of the concrete structure is the damage level that can be determined from the inspection results, and includes, for example, the degree of cracking in the outer wall, the depth and type of discoloration, the area of the discoloration range, the corrosion level, etc.

For example, an image of cracks in the outer wall of a structure is created by detecting them from an image of the external appearance of the outer wall. The size of cracks can be divided into two levels. Specifically, the level of damage is determined depending on whether or not it can be recognized by visually viewing an image at the same magnification. For example, cracks that are large enough to be visually recognized are classified as the first level, and cracks that are too small to be visually recognized are classified as the second level.

The crack image may be created manually by a worker, or may be automatically created by machine learning using artificial intelligence technology.

FIG. 15 is a diagram for explaining switching of display of images of cracks in an outer wall. As shown in FIG. 15A, when the magnification exceeds the second standard, the display processing unit 102 first displays the first level crack image superimposed on the three-dimensional image of the concrete structure on the screen 200. Next, as shown in FIG. 15(b), when the magnification magnification becomes even larger than the second standard, for example, the display processing unit 102 controls the display processing unit 102 to In this case, in addition to the first level crack (L1) image, a second level crack (L2) image is displayed superimposed on the three-dimensional image of the concrete structure on the screen 200.

As explained above, in this embodiment, the position information acquisition unit 120 acquires position information that specifies the relative position of the operator with respect to the concrete structure, and the data to be displayed first on the screen is switched based on the relative position. . In this way, according to the present embodiment, the inspection results and repair contents of the concrete structure can be easily grasped by the administrator, and the operator can easily understand the inspection results and repair details of the concrete structure, and when working by viewing the screen of this system at the site of the concrete structure. Since the information corresponding to the location of the operator can be appropriately provided, the operator can efficiently access the necessary information.

Furthermore, in this embodiment, the display processing unit 102 switches the data to be displayed depending on the magnification of the screen display. In particular, in this embodiment, the display processing unit 102 generates an external image of a concrete structure, an image showing damage, and an image showing diagnostic analysis results, respectively, according to the first standard, second standard, and third standard of magnification. will be switched and displayed. As described above, according to the present embodiment, the content of the displayed image can be switched in stages according to the enlargement operation by the operator, which provides good operability.

Furthermore, in this embodiment, the damage level of the image to be displayed is set, for example, in response to an operator's screen enlargement operation (pinch out, etc.). For example, if the image shows the state of cracks in an outer wall, when the magnification becomes larger than the standard, the image changes from the image showing the rough state of the cracks to the image showing the state of finer cracks. As described above, according to the present embodiment, the damage level of the data displayed on the screen can be changed according to the operator's intuitive operation, so the operability is good.

(Fifth embodiment)
FIG. 16 is a functional block diagram logically showing the configuration of the concrete structure management device 100 of this embodiment. The concrete structure management device 100 of this embodiment is the same as any of the embodiments described above, except that it has a configuration that outputs an alarm of information regarding the management of concrete structures. Further, the configuration of the concrete structure management device 100 of this embodiment can be combined with the configurations of other embodiments within a consistent range. The concrete structure management device 100 includes the same display processing section 102 and reception section 104 as in FIG. 3, and further includes a monitoring section 130 and an alarm output section 132.

The monitoring unit 130 monitors whether information regarding the management of the concrete structure satisfies alarm criteria based on the inspection results or repair details. The alarm output unit 132 outputs an alarm when the alarm criteria are met.

Alarm criteria can be provided for each structure or area or section and/or for each inspection or repair item. Preferably, the alarm criteria can be set by an operator, and may be set by opening a settings menu on the terminal device 30. The alarm criteria may include a plurality of levels, and the form of the alarm may be changed so that different outputs are output depending on the level.

The form of alarm output is exemplified below, but is not limited to these.
(1) The image corresponding to the area or section where the alarm was detected is highlighted or blinked on the screen 200. Alternatively, an icon indicating the occurrence of an alarm is displayed near the location where the alarm occurs. When the icon is operated, detailed information about the contents of the alarm is displayed.
(2) Display a message in a pop-up window notifying that an alarm has occurred. Further, when an operation button or icon in the window is operated, detailed information on the contents of the alarm is displayed.
(3) The LED (Light Emitting Diode) display provided in the terminal device 30 is turned on and off. Alarm levels may be distinguished by the color or pattern of blinking lights.
(4) Output a voice message or warning sound from the speaker of the terminal device 30 to notify that an alarm has occurred. Alternatively, an audio output device installed at the work site outputs audio using wireless communication such as Bluetooth.
(5) Send a message to a prespecified destination (email address, phone number, etc.). The message sent to the mobile phone may be audio.
(6) Information indicating the occurrence of an alarm (for example, a message, an icon, etc.) is displayed on a screen indicating the contents of the inspection result (for example, the carbonation depth graph in FIG. 17, which will be described later).
(7) Display alarm history information on the screen or print it out.

As an example of monitoring by the monitoring unit 130, monitoring of concrete corrosion start time will be described. Concrete corrosion is one of the causes of concrete carbonation. Therefore, the monitoring unit 130 determines whether the remaining carbonated thickness is below the reference value based on the measurement results of the concrete cover thickness and carbonation depth of the concrete structure, and determines whether the remaining carbonated thickness is equal to or less than the reference value. When the value falls below the standard value, it is determined that it is time for concrete corrosion to begin.

FIG. 17 is a diagram illustrating an example of an indicator 210 that indicates the remaining thickness of concrete after carbonation, which is displayed on the screen 200.
The neutralization depth is shown in a graph (indicator 210) with the horizontal axis representing the cover thickness of the concrete structure. Two reference values are used as criteria for determining the corrosion start time. The alarm output unit 132 issues a notification when the neutralization depth exceeds the first reference value 212 and outputs an alarm when the neutralization depth exceeds the second reference value 214.

In the example of FIG. 17(a), the value of the graph 216a of the neutralization depth is less than the first reference value. In the example of FIG. 17(b), the value of the graph 216b of the neutralization depth exceeds the first reference value 212. Therefore, the alarm output unit 132 notifies the user that the neutralization depth exceeds the first reference value 212. In the example of FIG. 17C, the value of the graph 216c of the neutralization depth exceeds the second reference value 214. Therefore, the alarm output unit 132 outputs an alarm to the user indicating that the neutralization depth exceeds the second reference value 214.

Further, the graph 216a, the graph 216b, and the graph 216c may be displayed in different colors. For example, if the graph 216a is green, the graph 216b is yellow, and the graph 216c is red, the operator can intuitively recognize the danger level. Alternatively, the graph 216a may be a normal display, the graph 216b may be a display with a slow blinking interval below a predetermined speed, and the graph 216c may be a display with a blinking interval faster than the graph 216b.

Furthermore, in the example of FIG. 17(d), a graph 218 is shown so that the progress of carbonation at each inspection period can be seen. In the graph 218, the current, previous, and two previous test results are displayed together in a way that allows them to be identified. The display processing unit 102 uses history information to display a graph using test results that have been conducted multiple times in the past. As shown in Figure 17(d), the values up until the previous time, the values up to the previous time, and the current value may be displayed in different display formats (display color, pattern, emphasis, blinking, etc.), or they can be displayed simply as lines. It may be displayed separated by . Further, the graph 216a in FIG. 17(a), the graph 216b in FIG. 17(b), and the graph 216c in FIG. 17(c) may be displayed side by side in close proximity. In addition, in FIG. 17(d), labels such as "this time", "previous time", and "previous time" are shown, but information on each inspection date and time (for example, information on the fiscal year, etc.) is displayed on the graph 218. Good too. Further, the detailed contents of each test may be displayed according to an operation requested by the operating system.

By doing this, it is possible to check the progress of carbonation together with past information before the corrosion start time arrives, so it is possible to formulate an appropriate repair plan and take countermeasures without missing the time for countermeasures.

As described above, in this embodiment, the monitoring unit 130 monitors whether information regarding the management of concrete structures satisfies the alarm criteria, and when the alarm criteria is met, the alarm output unit 132 outputs an alarm. As described above, according to the present embodiment, the inspection results and repair details of a concrete structure can be easily grasped by the administrator, and furthermore, based on the information on the inspection results and repair details, not only alarm monitoring but also past Since the results of several tests can be displayed together, it is possible to catch signs of problems before they occur, allowing appropriate measures to be taken early.
