Modes for Carrying Out the Invention

[0009] 〔Embodiment 1〕 <Configuration of Management Device 1> FIG. 1 is a block diagram showing an example of the configuration of a management device 1 according to Embodiment 1 of the present invention. The following description not only explains the management device 1 but also the management method for managing pipelines on a geographic information system. The management device 1 is a device for managing pipelines on a geographic information system, and may be, for example, a PC (Personal Computer), or a portable information terminal such as a smartphone or a tablet.

[0010] Examples of the pipelines managed by the management device 1 include water pipelines such as aqueducts, water transportation facilities such as water pipe bridges, and tunnels. Examples of the pipes included in the pipelines managed by the management device 1 include water supply pipes, drain pipes, gas pipes, electric wire pipes, telephone line pipes, pipes through which LAN (Local Area Network) cables are passed, and ducts. The pipes managed by the management device 1 are linear structures with a circular, rectangular, horseshoe-shaped, trapezoidal, or oval cross-section.

[0011] As shown in FIG. 1, the management device 1 includes a reception unit 11, a display unit 12, a storage unit 13, and a control unit 14. The reception unit 11 receives the selection of a pipe included in a pipeline on the geographic information system. The reception unit 11 is an operation unit operable by a user, and is, for example, a mouse, a keyboard, or a touch panel.

[0012] The display unit 12 displays the pipeline on the geographic information system and also displays the processing content by the control unit 14. The storage unit 13 stores the processing content by the control unit 14. Further, the storage unit 13 may store a program for operating the geographic information system. The control unit 14 controls each unit included in the management device 1. Further, the control unit 14 may read out the program stored in the storage unit 13 and operate the geographic information system.

[0013] <Regarding Pipe T1> FIG. 2 is a schematic diagram showing a pipe T1 included in a pipeline as an example of an object to be managed by the management device 1 shown in FIG. 1. FIG. 3 is a diagram showing an example of a screen displayed on the display unit 12 provided in the management device 1 shown in FIG. 1. As shown in FIG. 2, the pipe T1 has an outer surface T2 and an inner surface T3. Here, consider the case where there are dirt A1, cracks A2, and rust A3 on the outer surface T2 of the pipe T1.

[0014] The storage unit 13 stores a captured image of the outer surface T2 of the pipe T1 and a captured image of the inner surface T3 of the pipe T1. The captured image of the outer surface T2 is an image captured of the outer surface T2 by a camera provided in, for example, a drone or the like, and the captured image of the inner surface T3 is also an image captured of the inner surface T3 by a camera provided in a drone or the like.

[0015] The control unit 14 generates an exploded view 202 shown in FIG. 3 by cutting open and expanding the captured image of the outer surface T2 at the bottom D1 of the outer surface T2 of the pipe T1. The control unit 14 stores the generated exploded view 202 in the storage unit 13. The exploded view 202 shows the outer surface T2 of the pipe T1 two-dimensionally.

[0016] Coordinates are set in the exploded view 202. In the exploded view 202, for example, the horizontal direction is set as the X-axis direction and the upward direction is set as the Y-axis direction. Also, in the exploded view 202, for example, the origin O is set at the intersection of the left end and the lower end in the figure showing the outer surface T2 of the pipe T1.

[0017] The top B1 of the outer surface T2 of the pipe T1 is shown by a dotted line in the exploded view 202. Also, the outer circumference length CP1 of the pipe T1 is shown in the exploded view 202, and the length L1 in the extending direction of the pipe T1 is shown. The length CP1 and the length L1 are shown numerically in the exploded view 202 and are an example of the management information of the pipe T1. Also, the process of the display unit 12 displaying the length CP1 and the length L1 is an example of the information display step.

[0018] Further, the control unit 14 generates a developed view 203 by cutting and developing a captured image of the inner surface T3 at the bottom D2 of the inner surface T3 of the pipe T1. The control unit 14 stores the generated developed view 203 in the storage unit 13. The developed view 203 shows the inner surface T3 of the pipe T1 two-dimensionally.

[0019] Coordinates are set in the developed view 203. In the developed view 203, for example, the horizontal direction is set as the X-axis direction and the upward direction is set as the Y-axis direction. Also, in the developed view 203, for example, an origin O is set at the intersection of the left end and the lower end in the figure showing the inner surface T3 of the pipe T1.

[0020] In the developed view 203, the ceiling portion B2 of the inner surface T3 of the pipe T1 is shown by a dotted line. Also, the developed view 203 shows the inner circumference length CP2 of the pipe T1 and the length L1 in the extending direction of the pipe T1. The length CP2 is numerically shown in the developed view 203 and is an example of the management information of the pipe T1. Also, the process of the display unit 12 displaying the length CP2 is an example of the information display step.

[0021] The control unit 14 causes the display unit 12 to display a diagram 201 showing a pipeline. In FIG. 3, regarding the diagram TL1 of the pipe T1 included in the diagram 201, when the user operates the reception unit 11 to select the pipe T1, the reception unit 11 receives the selection of the pipe T1. The control unit 14 causes the display unit 12 to display a developed view 202 showing the outer surface T2 of the pipe T1 selected by the reception unit 11 and a developed view 203 showing the inner surface T3 of the pipe T1 selected by the reception unit 11. The display unit 12 displays the developed views 202 and 203.

[0022] At this time, the control unit 14 acquires the developed views 202 and 203 from the storage unit 13. The process of the display unit 12 displaying the developed views 202 and 203 is an example of the developed view display step. Note that the control unit 14 may cause the display unit 12 to display only one of the developed views 202 and 203.

[0023] The developed view 202 includes figures corresponding to the management information indicating the state of the pipe T1. For example, the developed view 202 includes a figure F1 corresponding to the management information I1, a figure F2 corresponding to the management information I2, and a figure F3 corresponding to the management information I3. The figure F1 is a figure indicating the stain A1 by dots, the figure F2 is a figure indicating the crack A2 by a line, and the figure F3 is a figure indicating the rust A3 by a quadrilateral.

[0024] When the reception unit 11 receives the selection of the figure F1, the control unit 14 causes the display unit 12 to display the management information I1 corresponding to the figure F1. Similarly, when the reception unit 11 receives the selection of the figure F2, the control unit 14 causes the display unit 12 to display the management information I2 corresponding to the figure F2. Also, when the reception unit 11 receives the selection of the figure F3, the control unit 14 causes the display unit 12 to display the management information I3 corresponding to the figure F3.

[0025] At this time, the control unit 14 acquires the management information I1 to I3 from the storage unit 13. The display unit 12 displays the management information I1 to I3. Thereby, the user can visually grasp the state of the pipe T1 by checking the figures F1 to F3. Also, since the user can check the positions of the figures F1 to F3 in the developed view 202, the user can grasp the positions of the abnormal portions of the pipe T1. The process of the display unit 12 displaying the management information I1 to I3 is an example of the information display step.

[0026] In addition, the control unit 14 causes the display unit 12 to display a developed view two-dimensionally showing at least one of the inner surface T3 and the outer surface T2 of the pipe T1 selected by the reception unit 11, and causes the display unit 12 to display the management information I1 to I3 of the pipe T1 associated with the developed view. Thereby, the display unit 12 displays the developed view and the management information I1 to I3. In other words, regarding the display of the developed view, the control unit 14 causes the display unit 12 to display a developed view two-dimensionally showing at least one of the inner surface T3 and the outer surface T2 of the pipe T1 selected on the geographic information system among the pipelines.

[0027] The management information I1 to I3 is information indicating the investigation results when the state of the outer surface T2 of the pipe T1 is investigated. That is, the management information I1 to I3 is information indicating the state of the outer surface T2 of the pipe T1. The investigation results are, for example, the corrosion locations, crack positions, or paint peeling locations on the outer surface T2 of the pipe T1. The management information I1 to I3 is stored in the storage unit 13 in association with the developed view 202. The management information I1 to I3 is information that is input and stored in the storage unit 13 by the user's operation of the reception unit 11.

[0028] Also, the management information I1 to I3 is information indicating the content and evaluation of abnormal locations such as damage or defects occurring on the outer surface T2 of the pipe T1. For example, the content of the damage in the management information I1 is dirt, the content of the damage in the management information I2 is a crack, and the content of the damage in the management information I3 is rust. The evaluation of the damage indicates the degree of damage according to the content of the damage. Note that the control unit 14 may cause the display unit 12 to display the management information of the pipe T1 associated with the developed view 203, similar to the management information I1 to I3.

[0029] The diagram 201 may include the inspection information I11 of the pipe T1. The inspection information I11 is information indicating the inspection history of the pipe T1 and includes information indicating the inspection date, inspection items, inspector, and damage evaluation. It is also possible for the user to operate the reception unit 11 to select the inspection date among the inspection information I11.

[0030] In this case, the reception unit 11 receives the selection of the inspection date in the inspection information I11. The control unit 14 may cause the display unit 12 to display a developed view showing at least one of the inner surface T3 and the outer surface T2 of the pipe T1 corresponding to the inspection date selected by the reception unit 11. Thereby, the user can confirm at least one of the inner surface T3 and the outer surface T2 of the pipe T1 for each inspection date and can confirm the past inspection information in the developed view. Also, for each piece of related information regarding the pipe T1 such as inspection, cleaning, or repair, a developed view is displayed on the display unit 12, and the related information can be managed on the developed view.

[0031] Furthermore, the reception unit 11 may receive the selection of a plurality of inspection dates in the inspection information I11. In this case, the control unit 14 may cause the display unit 12 to display a developed view showing at least one of the inner surface T3 and the outer surface T2 of the pipe T1 corresponding to each of the plurality of inspection dates received by the reception unit 11. Thereby, the user can compare the developed views of the pipe T1 corresponding to each of the plurality of inspection dates.

[0032] Also, when the diagram 201 includes a plurality of pipes, the reception unit 11 may receive the selection of the plurality of pipes included in the diagram 201 on the geographic information system. At this time, the control unit 14 may cause the display unit 12 to display a developed view two-dimensionally showing at least one of the inner surface and the outer surface of the plurality of pipes received by the reception unit 11. Thereby, the user can compare the developed views corresponding to each of the plurality of pipes.

[0033] As described above, the management device 1 displays a developed view two-dimensionally showing at least one of the inner surface T3 and the outer surface T2 of the pipe T1 selected on the geographic information system, and displays the management information of the pipe T1 associated with the developed view. By these displays by the management device 1, in the geographic information system, since the management information of the pipe T1 can be confirmed together with the developed view, the confirmation of the management information of the pipe T1 can be made visually easy to understand by the developed view.

[0034] Also, the user can manage on the developed view 202 the result of inspecting the outer surface T2 of the pipe T1 with respect to the exposed pipeline. The control unit 14 can also cause the display unit 12 to display the captured images of the outer surface T2 and the inner surface T3 of the pipe T1 as one piece of image data as one developed view. Since the user can view the developed view on the geographic information system, the developed view can be utilized for on-site surveys.

[0035] Note that search information for searching management information I1 to I3 may be associated with the development diagram 202. The search information is a character string associated with the development diagram 202 so that a user can search for the management information I1 to I3 by operating the reception unit 11. That is, the search information is information for causing the management information I1 to I3 to be displayed as search results when the user operates the reception unit 11 to input a keyword and the character string corresponding to the keyword is included in the character strings corresponding to the management information I1 to I3.

[0036] Since search information for searching management information I1 to I3 is associated with the development diagram 202, the management information I1 to I3 can be searched, and the desired management information can be immediately confirmed together with the development diagram 202.

[0037] <Modification Example 1> FIG. 4 is a diagram showing a screen P1 displayed by the display unit 12 in Modification Example 1 of the present invention. Consider a case where a diagram TL1 of the pipe T1 is displayed on the screen P1 displayed by the display unit 12 as shown by reference numeral 401 in FIG. 4. In this case, when the reception unit 11 receives the selection of the pipe T1, the control unit 14 may switch the display from the display of the diagram TL1 to the display of the development diagrams 202 and 203 with respect to the screen P1 on which the diagram TL1 indicating the pipe T1 is displayed. The screen P1 is a window as a rectangular display area that displays at least a part of the screens displayed by the display unit 12.

[0038] By the control unit 14 performing the display switching, as shown by reference numeral 402 in FIG. 4, the development diagrams 202 and 203 are displayed on the screen P1 displayed by the display unit 12. In this way, since the display is switched from the display of the diagram TL1 to the display of the development diagrams 202 and 203 with respect to the screen P1 on which the diagram TL1 indicating the pipe T1 is displayed, there is no need to newly display a screen for displaying the development diagrams 202 and 203 separately from the screen P1 on which the diagram TL1 is displayed. Therefore, the development diagrams 202 and 203 can be confirmed on the screen P1 while maintaining the screen P1 on which the diagram TL1 was displayed.

[0039] Further, in the screen P1 displayed by the display unit 12, the control unit 14 may display a diagram showing a pipe different from the pipe T1 while maintaining the display of the developed diagrams 202 and 203 of the diagram TL1.

[0040] <Modification 2> In the diagram 201 shown in FIG. 3, the presence or absence of a developed diagram for each of the plurality of pipes may be indicated by a difference in color. Thereby, when the user checks the diagram 201, the user can grasp the presence or absence of the developed diagram for each of the plurality of pipes without selecting a pipe.

[0041] <Modification 3> The control unit 14 may refer to the update timing of the pipe T1 from the storage unit 13 and cause the display unit 12 to display an alarm indicating that the update timing of the pipe T1 is approaching at a timing a predetermined time before the update timing of the pipe T1. The update timing of the pipe T1 is the timing at which replacement of the currently laid pipe T1 is recommended. The control unit 14 may cause the sound output unit (not shown) provided in the management device 1 to output an alarm indicating that the update timing of the pipe T1 is approaching.

[0042] Further, the control unit 14 may refer to the inspection timing of the pipe T1 from the storage unit 13 and cause the display unit 12 to display an alarm indicating that the inspection timing of the pipe T1 is approaching at a timing a predetermined time before the inspection timing of the pipe T1. The control unit 14 may cause the above-described sound output unit to output an alarm indicating that the inspection timing of the pipe T1 is approaching.

[0043] Furthermore, the control unit 14 may refer to the service life of the pipe T1 from the storage unit 13 and cause the display unit 12 to display an alarm indicating that the life of the pipe T1 is approaching at a timing a predetermined time before the life of the pipe T1. The control unit 14 may cause the above-described sound output unit to output an alarm indicating that the life of the pipe T1 is approaching. As described above, the user can grasp the update timing, inspection timing, or life of the pipe T1 at an appropriate timing.

[0044] 〔Embodiment 2〕 Embodiment 2 of the present invention will be described below. For the sake of convenience of explanation, members having the same functions as those described in Embodiment 1 are denoted by the same reference numerals, and their descriptions will not be repeated. FIG. 5 is a block diagram showing an example of the configuration of a management system 100 according to Embodiment 2 of the present invention.

[0045] As shown in FIG. 5, the management system 100 includes a management device 1A and a server 2 that can communicate with the management device 1A. The management system 100 is a system for managing pipelines by the management device 1A and the server 2. The management device 1A is different in that it further includes a communication unit 15 compared to the management device 1. The communication unit 15 can communicate with the communication unit 22 of the server 2 via the network NT.

[0046] The server 2 includes a storage unit 21, a communication unit 22, and a control unit 23. The storage unit 21 stores the processing contents by the control unit 23. Note that the information stored in the storage unit 13 of the management device 1 in Embodiment 1 may be stored in the storage unit 21 of the server 2. In this case, the control unit 14 of the management device 1A acquires information from the storage unit 21 by communicating with the communication unit 22 of the server 2 using the communication unit 15. The control unit 23 controls each unit included in the server 2. The communication unit 22 can communicate with the communication unit 15 of the management device 1A via the network NT.

[0047] The captured image of the outer surface T2 or the inner surface T3 of the pipe T1 may be stored in the storage unit 21 of the server 2. Specifically, when the control unit 14 of the management device 1A acquires the captured image of the outer surface T2 or the inner surface T3 of the pipe T1, the control unit 14 transmits the acquired captured image to the communication unit 22 of the server 2 using the communication unit 15. The control unit 23 of the server 2 stores the captured image received by the communication unit 22 from the communication unit 15 in the storage unit 21.

[0048] Also, the generation of the development diagrams 202 and 203 may be executed by the control unit 23 of the server 2. Specifically, the control unit 23 acquires a photographed image of the outer surface T2 of the pipe T1 from the storage unit 21, and generates the development diagram 202 based on the acquired photographed image. The control unit 23 stores the generated development diagram 202 in the storage unit 21. Similarly, the control unit 23 acquires a photographed image of the inner surface T3 of the pipe T1 from the storage unit 21, and generates the development diagram 203 based on the acquired photographed image. The control unit 23 stores the generated development diagram 203 in the storage unit 21. The management information I1 to I3 is stored in the storage unit 21 in association with the development diagram 202.

[0049] Furthermore, when the selection of the pipe T1 is received by the reception unit 11, the control unit 14 of the management device 1A transmits a request instruction for requesting the development diagrams 202 and 203 to the communication unit 22 of the server 2 using the communication unit 15. The control unit 23 of the server 2 acquires the development diagrams 202 and 203 from the storage unit 21, and transmits the acquired development diagrams 202 and 203 to the communication unit 15 of the management device 1A using the communication unit 22. The control unit 14 of the management device 1A acquires the development diagrams 202 and 203 received by the communication unit 15 from the communication unit 22. Then, the control unit 14 causes the display unit 12 to display the development diagrams 202 and 203.

[0050] When the selection of the figure F1 is received by the reception unit 11, the control unit 14 may acquire the management information I1 corresponding to the figure F1 from the server 2 in the same manner as the acquisition of the development diagrams 202 and 203. The control unit 14 causes the display unit 12 to display the acquired management information I1. Similarly, the control unit 14 may acquire the management information I2 and I3 from the server 2.

[0051] In the management system 100, the management device 1A and the server 2 may be located in the country, but the management device 1A may be located in the country while the server 2 may be located abroad. Consider the case where the management device 1A is located in the country while the server 2 is located abroad. In this case, the effect that the confirmation of the management information of the pipe T1 can be visually made easy by the developed view can be obtained by the display of the management device 1A existing in the country and is exerted in the country.

[0052] 〔Summary〕 The management method according to Aspect 1 of the present invention is a management method for managing pipelines on a geographic information system, including a developed view display step of displaying a developed view that two-dimensionally shows at least one of the inner surface and the outer surface of a pipe selected on the geographic information system among the pipelines, and an information display step of displaying management information of the pipe associated with the developed view displayed in the developed view display step.

[0053] A developed view that two-dimensionally shows at least one of the inner surface and the outer surface of a pipe selected on the geographic information system is displayed, and the management information of the pipe associated with the developed view is displayed.

[0057] Since the screen for displaying the diagram showing the pipe is switched from the display of the diagram to the display of the developed view, it is not necessary to newly display a screen for displaying the developed view separately from the screen for displaying the diagram. Therefore, the developed view can be confirmed on the screen while maintaining the screen on which the diagram was displayed.

[0059] The management device displays a developed view two-dimensionally showing at least one of the inner surface and the outer surface of the pipe selected on the geographic information system, and also displays management information of the pipe associated with the developed view. By these displays by the management device, in the geographic information system, the management information of the pipe can be confirmed together with the developed view, so that the confirmation of the management information of the pipe by the developed view can be made visually easy to understand.

[0060] The management system according to Aspect 6 of the present invention includes the management device according to Aspect 5 described above and a server capable of communicating with the management device, and the pipeline may be managed by the management device and the server.
