Hereinafter, embodiments of the information management system and the information management method will be described in detail with reference to the drawings. Reference numeral 1 in FIG. 1 is the information management system of the present embodiment.

Plants, including nuclear power plants, thermal power plants, chemical plants, or factories, undergo regular inspections or maintenance for stable operation. In such a plant, various objects such as buildings, equipment, equipment, and structures are provided. The information management system 1 of the present embodiment manages the target information necessary for inspection or maintenance of these objects. Furthermore, it is possible to examine the arrangement of these objects or manage the modification history.

The equipment includes, for example, valves, motors, switchboards, electrical components, computers and the like. Further, the structure includes, for example, a tank, a pipe, a support member, a skeleton constituting a building, a through hole provided in the skeleton, a room, a passage, a site, and the like.

As shown in FIG. 1, the information management system 1 is connected to the Internet 2. The information management system 1 may be implemented on a cloud server outside the plant, or may be implemented on a server inside the plant.

The user U1 as an administrator who manages the work of inspection or maintenance of the plant accesses the information management system 1 by using the user terminal 3 connected to the Internet 2. Further, the worker W who works at the work site accesses the information management system 1 by using the site terminal 4 connected to the Internet 2.

The user terminal 3 handled by the user U is composed of a predetermined computer such as a desktop PC, a notebook PC, or a tablet PC, for example. The user terminal 3 includes an input device such as a mouse or a keyboard used for inputting predetermined information according to the operation of the user U. The input operation of the present embodiment includes a click operation using a mouse or a touch operation using a touch panel.

Further, the user terminal 3 includes a display device such as a display 5 that displays a screen related to the target information. The display 5 may be separate from the computer body or may be integrated. When the information management system 1 is accessed via the user terminal 3 and the target information is displayed on the display 5, the control of the screen of the display 5 is controlled by the information management system 1.

In this embodiment, the display 5 is illustrated as the display device, but other modes may be used. For example, information may be displayed using a projector. Further, a printer that prints information on a paper medium may be used instead of the display 5. That is, a projector or a printer may be included as an object controlled by the information management system 1.

The field terminal 4A handled by the worker W is composed of, for example, a smartphone 4A provided with a display. The smartphone 4A is equipped with a camera 6 for recording the situation at the site. The display of the smartphone 4A is not only a display device but also a touch panel as an input device. The input operation of the present embodiment includes a touch operation using a touch panel.

Further, the different types of field terminals 4B handled by the other worker W are composed of a wearable computer 4B (smart glasses) provided with the transmissive head-mounted display 7 worn by the worker W. The wearable computer 4B may have a structure separated from the transmissive head-mounted display 7. The transmissive head-mounted display 7 is also equipped with a camera that records the situation at the site. For example, the camera may be an omnidirectional camera 9 installed on the crown of the helmet 8 worn by the worker W and capable of capturing an omnidirectional image (omnidirectional image) which is a 360-degree panoramic image. The omnidirectional camera 9 can take images in all directions, up, down, left, right, front and back, using, for example, a fisheye lens.

The field terminal 4 may be composed of a tablet PC or a notebook PC. In addition, it is composed of devices having a shooting function, a call function, and a communication function, and may be composed of a plurality of devices having each function.

The user U1 as an administrator accesses the information management system 1 by using the user terminal 3, and causes the display 5 of the user terminal 3 to display a screen relating to the target information regarding the object. For example, when a predetermined area of the plant is to be inspected, a sketch showing the area is displayed on the browser 10 (web browser) of the display 5 (see FIG. 4). Further, when the valve is inspected in a predetermined area, the design drawing, image, 3D-CAD data, etc. of the valve to be inspected are displayed on the display 5 (see FIG. 7).

Then, the user U creates the work plan 11 and hands it to the worker W. The work plan 11 may be in the form of an electronic file or a paper medium. Based on this work plan 11, the worker W carries out the inspection work. The worker W uses the site terminal 4 to access the information management system 1 and displays a screen related to the target information regarding the object on the display of the site terminal 4.

Here, when the user U creates the work plan 11, when the content such as 3D-CAD data is displayed on the display 5 of the user terminal 3, the user U uses the mouse. Alternatively, an input device such as a keyboard can be used to arbitrarily change the display mode of the screen such as the viewpoint (angle) or the magnification (scale).

The worker W who has been given the work plan 11 can easily understand the contents if he / she can see the display mode of the screen actually seen by the user U as it is. Therefore, in the present embodiment, it is possible to output a character string indicating a reproduction URL as a reproduction identifier, a two-dimensional code indicating the URL, and a registered name that can reproduce the display mode of the screen (see FIG. 6). ). In this way, the reproduction identifier can be easily described in a predetermined document such as the report 12. Here, the reproduction URL is one of the embodiments of the reproduction identifier. This reproduction identifier may be other link information and is not limited to a character string or a two-dimensional code. Further, it may be possible to output a figure indicating the reproduction URL.

The user U describes the output reproduction URL in the work plan 11 and passes it to the worker W. Then, by inputting the reproduction URL into the browser 10 (see FIG. 4), the worker W can see the display mode of the screen actually seen by the user U as it is. Further, when the content such as 3D-CAD data is displayed, the worker W can further change the viewpoint seen by the user U.

Further, the user U1 who is the administrator creates a report 12 in which the reproduction URL is described after the inspection work, and passes it to another user U2. The report 12 may be in the form of an electronic file or a paper medium. Then, the other user U2 can see the display mode of the screen actually seen by the user U1 who is the administrator as it is by inputting the reproduction URL into the browser 10.

In the present embodiment, different users U1 and U2 or between the user U1 and the worker W can share the completely same screen display mode, so that they can easily communicate with each other. In this way, the target information can be shared by the different users U1 and U2 sharing the reproduction URL. Information can be shared at the same position on the page in the case of books and at the same viewpoint or magnification in the case of 3D-CAD data. Then, it is possible to share the details of the information to be surely confirmed. In addition, the information used in the report 12 can be easily accessed by describing the reproduction URL together with the captured screen display in the report 12 or the like.

The method of sharing the reproduction URL may be shared as link information of electronic data, or may be shared as a two-dimensional code. For example, the camera 6 of the field terminal 4A having the two-dimensional code reading function may be used to read the two-dimensional code and read the screen of the target information.

Conventionally, as a method of saving the screen, there is a method of capturing the screen and saving it as image data. However, in this case, since the individual information to be displayed is not saved, it is difficult to grasp which part of which information. On the other hand, in the present embodiment, it is possible to read out the extracted information and the detailed part thereof. Further, it is possible to improve work efficiency when the work is carried out by a plurality of users U or W.

In this embodiment, information added by maintenance work of a plant or a building such as a patrol inspection can be stored. In the maintenance work, the inspection records are sequentially added by the patrol inspection or the overhaul inspection performed based on the work plan 11. The information management system 1 makes it easy for the user U or the worker W to grasp the work plan 11 and the actual results. Then, the equipment to be inspected can be extracted by the search function, and the work plan 11 including the list of inspection targets can be created. Based on this work plan 11, the worker W inspects the predetermined equipment and records the inspection result.

For example, by selecting a device or area on the user terminal 3, it is possible to confirm the inspection record registered for each inspection target, that is, the state of the site. For example, the open / closed state of the valve can be visualized and confirmed by the difference in color. Similarly, at the site terminal 4, it is possible to confirm the state of the previous inspection record of the inspection target.

In addition, the work plan 11 is created using the information management system 1 and downloaded to the site terminal 4 used at the site. Then, after the work is completed, the result is uploaded from the site terminal 4. For example, a device or area to be worked on is selected on the screen of the field terminal 4, and detailed information and coordinates related to the device or area are listed. In addition, work contents can be entered in this list. The worker W can collectively acquire information on books or drawings necessary for the work. After the work, as a result of the work, the date and time and the information of the person in charge are added, and the work record is saved in the site terminal 4 and uploaded to the information management system 1, so that the information after the inspection and the existing information It is possible to link with the information of the data.

In addition, the field terminal 4 has a position information measurement function. For example, GPS may be used at an outdoor site. Since GPS cannot be used indoors, SLAM (Simultaneous Localization And Mapping) technology that estimates the self-position using the information acquired by the camera or sensor of the field terminal 4 may be used. Further, position estimation by communication with a beacon provided at a predetermined position may be used. Further, a method such as PDR (Pedestrian Dead Reckoning) that estimates the movement locus from the information acquired based on the accelerometer or the gyro may be used.

When the work plan 11 is created by the information management system 1 of the present embodiment, the position information of the object to be worked may be extracted from the design data such as 3D-CAD. Further, by using the on-site terminal 4 having the position information measurement function, the navigation function to the work place may be provided. Further, the site terminal 4 can manage the location information in association with the information acquired at the site such as a check sheet such as an inspection record, a photograph, and a video.

The photograph or video acquired by the field terminal 4 may be 360-degree content (see FIG. 8) such as an all-around image. For example, by adjusting the shooting position, the height at the time of shooting, and the orientation at the time of shooting, the 360-degree content can be confirmed in the same manner as the 3D-CAD data. Further, when adjusting the shooting position, the height at the time of shooting, and the orientation at the time of shooting, the feature points may be extracted from the acquired image and automatically displayed at the position overlapping with the 3D-CAD. ..

Next, the display mode of the screen of the browser 10 will be described with reference to the screen views of FIGS. 4 to 9. It should be noted that these display modes are examples, and other modes may be used. Further, the browser 10 can be displayed on either the user terminal 3 or the field terminal 4.

Further, a screen showing the target information being displayed on the data display unit 18 and a screen showing detailed information about the target information may be displayed side by side.

The work plan creation unit 40 creates a work plan 11. For example, when the target information displayed on the screen of the user terminal 3 is related to an arbitrary area of the work site, a list related to the work in the area is output. In this way, it is possible to make a work plan such as inspection work in any area of the work site.

The designated reception unit 41 accepts the designation of the display mode of the screen at an arbitrary time point. The designation of the display mode of the screen means that the user U clicks the browser shot button 20 or the view shot button 27. Here, the reproduction information storage unit 33 stores the reproduction information of the display mode of the screen at the time when the designated reception unit receives the designation. For example, when the user U clicks the browser shot button 20 or the view shot button 27, the reproduction information indicating the display mode of the screen at that time is stored in the reproduction information storage unit 33. In this way, the user U can specify the display mode of the screen at an arbitrary time point, and then reproduce the display mode of the screen at an arbitrary time point.

The reproduction identifier output unit 42 outputs the reproduction identifier stored in the reproduction information storage unit 33 in association with the reproduction information when the designation reception unit 41 receives the designation of the display mode of the screen at an arbitrary time point. For example, a character string indicating a reproduction URL as a reproduction identifier, a two-dimensional code, and a registered name are output on the screen of the user terminal 3 (see FIG. 6).

The reproduction identifier reception unit 43 accepts the input of the reproduction identifier. For example, the worker W, who has been given the reproduction URL by the user U, inputs the reproduction URL into the address bar 14 (see FIG. 4) of the browser 10 with the character string of the reproduction URL as the reproduction identifier. The reproduction identifier reception unit 43 receives the input reproduction URL.

The reproduction information specifying unit 44 specifies the reproduction information stored in the reproduction information storage unit 33 in association with the reproduction identifier received by the reproduction identifier reception unit 43.

The display mode reproduction unit 45 reproduces the display mode of the screen based on the reproduction information specified by the reproduction information identification unit 44. In this way, the display mode of the screen can be reproduced using the reproduction identifier as a key.

As shown in FIG. 3, the design information database 46 stores target information including at least one of a drawing related to the plant and CAD data.

In the design information database 46, various data such as 3D-CAD data, piping instrumentation drawing (P & ID) data, outline drawing and structural drawing data, and layout drawing data are stored. The design information database 46 stores data indicating design information such as a building or equipment provided in the plant. For example, the 3D-CAD data includes the dimensions of the structure and the like. The outline drawing and structural drawing data include design materials or specifications related to the structure and the members constituting the structure. The layout drawing data includes drawings related to layout information.

The object information database 47 stores the object information about the object provided in the plant. The object information database 47 stores, for example, various data related to structures such as book data and drawing data.

Various data such as scan data, photograph and moving image data, and work record data are stored in the site information database 48. The site information database 48 stores target information including at least one of laser scan data, photographs, and moving images added during the operation of the plant. That is, various data acquired by the worker W using the site terminal 4 at the work site are stored. For example, photographs or moving images taken at the site, laser scan data (for example, point cloud data) acquired after construction or modification are stored. In addition, data added by plant operation such as patrol inspection may be saved. In this way, it is possible to manage a huge amount of target information added during the operation of the plant.

As shown in FIG. 3, the management database 49 stores attribute information regarding the attributes of the object. For example, attribute information such as a name or specification related to a structure as an object is stored. This management database 49 has an object management table (see FIG. 12). In this way, it is possible to improve the efficiency of searching for information on the object of the plant.

As shown in FIG. 12, in the object management table, various data are registered in association with the object ID as the object identification information that can individually identify a plurality of objects. That is, the object management table registers the object information in association with the object ID. In this way, the information about the object can be managed by using the object identification information as a key.

For example, 3D position information indicating a three-dimensional position where an object is placed is registered. An area ID indicating an area where an object is placed is registered. A search keyword used to search for an object is registered. An image ID indicating an image of the object taken by the camera is registered. A 3D content ID indicating the 3D-CAD data of the object is registered. An omnidirectional image ID indicating an omnidirectional image in which an object is captured is registered. Terminal position information indicating the three-dimensional position of the field terminal 4 when various data related to the object is acquired is registered.

By inputting the information required by the user U into the browser 10 (see FIG. 4) as a search keyword, related target information is extracted from various databases 46 to 49. Then, in CAD data, book data, etc., it is displayed on the data screen of the corresponding portion. In addition, other related CAD data, the name of the book data, the information of the device in the displayed CAD data, and the like can be displayed.

Here, by allocating and saving the object ID (Tag No.) for the information stored in each of the databases 46 to 49, it is possible to efficiently extract the target information related to the search.

In the present embodiment, the target information (for example, the omnidirectional image) can be acquired by the site terminal 4 possessed by the worker W who performs the work. Then, the target information storage unit 32 stores the terminal position information indicating the position of the site terminal 4 when the target information is acquired in association with the target information. In this way, the target information can be searched using the position information as a key. For example, the terminal position information is registered as the viewpoint 28 (see FIG. 7). Then, by designating the viewpoint 28, the image acquired at that position can be displayed.

The omnidirectional camera 9 of the field terminal 4B can acquire the omnidirectional image as the target information. Moreover, the terminal position information stored in the object management table is the three-dimensional position information. That is, the target information storage unit 32 stores the terminal position information including the height of the site terminal 4B when the target information is acquired in association with the target information. In this way, since the height position of the omnidirectional camera 9 at the time of acquiring the omnidirectional image can be grasped, the actual situation of the work site can be grasped from the omnidirectional image.

As shown in FIG. 3, the display history database 50 stores data such as reproduction information. This reproduction information is stored in association with the reproduction identifier. That is, the screen display mode related to the target information is stored in the display history database 50. The display history database 50 has a display history management table (see FIG. 13). In this way, it is possible to manage the display mode of the screen regarding the information once confirmed.

As shown in FIG. 13, in the display history management table, various data as reproduction information are registered in association with the reproduction URL or the registered name as the reproduction identifier. For example, screen information indicating the number or types of screens being displayed on the browser 10 is registered. An image ID that can individually identify the image displayed on the browser 10 is registered. A 3D content ID that can individually identify the 3D content displayed on the browser 10 is registered. The display state such as the viewpoint (angle) or enlargement ratio (scale) of the 3D content being displayed on the browser 10 is registered. An omnidirectional image ID that can individually identify the omnidirectional image displayed on the browser 10 is registered. The display state such as the viewpoint (angle) or enlargement ratio (scale) of the omnidirectional image being displayed on the browser 10 is registered. That is, the reproduction information of the present embodiment includes screen information, an image ID, a 3D content ID, its display state, an omnidirectional image ID, and its display state. In addition, other data may be included in the reproduction information.

As shown in FIG. 3, in the present embodiment, the reproduction information is stored in the display history database 50. In this way, the predetermined user U1 can save the display mode of the screen of the target information extracted from the various databases 46 to 49 with respect to the information described in the report 12 as the examination result. .. Therefore, another user U2 can easily reproduce the target information and the display at the time of examination.

Further, the reproduction identifier associated with each reproduction information is stored in the display history database 50. Then, by sharing the reproduction identifier with different user U2 or worker W, it is possible to share the examination result. Furthermore, in addition to CAD models and design documents for each equipment, construction status information, patrol inspection records, site images, etc. are linked and managed by the object ID as object identification information, and related information can be searched. It can be made more efficient.

Further, when the user U selects the target information displayed on the data display unit 18, for example, a device such as a valve on the displayed drawing, detailed information on the selected portion can be additionally searched. Then, the detailed information can be extracted from the databases 46 to 49 and displayed. As a result, the related information can be searched in a batch, so that the search time can be shortened or the work efficiency can be improved.

Next, the information management process executed by the information management system 1 will be described with reference to the flowcharts of FIGS. 14 to 15. In addition, the above-mentioned FIGS. 1 to 13 are referred to as appropriate.

This process is a process that is repeated at regular intervals. By repeating this process, the information management method is executed in the information management system 1. Note that this process may be interrupted and executed while the information management system 1 is executing another main process.

In the following example, the mode in which the information management system 1 communicates with the user terminal 3 is illustrated, but the same processing flow is obtained even when the information management system 1 communicates with the field terminal 4.

As shown in FIG. 14, first, in step S11, the main control unit 30 of the information management system 1 determines whether or not the target information is input from the field terminal 4. That is, the worker W determines whether or not there is additional input of various data acquired by using the site terminal 4 at the work site. Here, if the target information is not input (NO in step S11), the process proceeds to step S13. On the other hand, if the target information is input (YES in step S11), the process proceeds to step S12.

In step S12, the target information storage unit 32 stores the target information input from the site terminal 4 in the site information database 48. The target information may be stored in other databases 46, 47, 49.

In step S13, the keyword reception unit 36 determines whether or not the input of the search keyword in the search keyword input field 15 (see FIG. 4) of the browser 10 has been accepted. Here, if the search keyword is not accepted (NO in step S13), the process proceeds to step S16. On the other hand, if the search keyword is accepted (YES in step S13), the process proceeds to step S14.

In step S14, the target information extraction unit 37 extracts the target information stored in the target information storage unit 32 in association with the keyword received by the keyword reception unit 36.

In the next step S15, the screen output unit 34 controls to output a screen related to the target information extracted by the target information extraction unit 37. For example, the browser 10 displayed on the display 5 of the user terminal 3 is made to display a screen related to the target information.

In step S16, the additional search reception unit 38 determines whether or not the search for detailed information regarding the target information displayed on the screen of the user terminal 3 has been accepted. If the search for detailed information is not accepted (NO in step S16), the process proceeds to step S19. On the other hand, when the search for detailed information is accepted (YES in step S16), the process proceeds to step S17.

In step S17, the detailed information extraction unit 39 extracts the detailed information received by the additional search reception unit 38 from the various databases 46 to 49 of the target information storage unit 32.

In the next step S18, the screen output unit 34 controls to output a screen related to the detailed information extracted by the detailed information extraction unit 39. For example, the browser 10 displayed on the display 5 of the user terminal 3 is made to display a screen related to detailed information.

In step S19, the work plan creation unit 40 determines whether or not the operation of displaying the work plan table including the list of inspection targets has been accepted. If the display of the work plan table is not accepted (NO in step S19), the process proceeds to step S22. On the other hand, when the display of the work plan table is accepted (YES in step S19), the process proceeds to step S20.

In step S20, the work plan creation unit 40 creates a work plan table based on the target information stored in the various databases 46 to 49 of the target information storage unit 32.

In the next step S21, the work plan creation unit 40 controls to output a screen related to the created work plan table. For example, the browser 10 displayed on the display 5 of the user terminal 3 is made to display the screen related to the work plan table. The work plan 11 in which the work plan table is described may be printed out.

In step S22, the change receiving unit 35 determines, for example, whether or not the user terminal 3 has accepted the change operation for changing the display mode of the screen. Here, if the operation for changing the display mode of the screen is not accepted (NO in step S22), the process proceeds to step S24. On the other hand, when the operation for changing the display mode of the screen is accepted (YES in step S24), the process proceeds to step S23.

In step S23, the screen output unit 34 controls to change the display mode of the screen based on the change operation received by the change reception unit 35. For example, the display mode of the screen is changed on the user terminal 3.

In step S24, the designated reception unit 41 determines whether or not the output of the reproduction identifier has been received. For example, it is determined whether or not the browser shot button 20 or the view shot button 27 has been clicked on the user terminal 3 (see FIG. 5). If the output of the reproduction identifier is not accepted (NO in step S24), the process proceeds to step S27. On the other hand, when the output of the reproduction identifier is accepted (YES in step S24), the process proceeds to step S25.

In step S25, the reproduction information storage unit 33 stores the reproduction information that can reproduce the display mode of the screen of the user terminal 3 at the time when the designated reception unit 41 receives the output of the reproduction identifier in association with the reproduction identifier.

In the next step S26, the reproduction identifier output unit 42 outputs the reproduction identifier stored in the reproduction information storage unit 33 in association with the reproduction information to the screen of the user terminal 3 (see FIG. 6).

In step S27, the reproduction identifier reception unit 43 determines whether or not the input of the reproduction identifier has been accepted. For example, on the user terminal 3, it is determined whether or not the reproduction URL has been input to the address bar 14 (see FIG. 4) or the reproduction identifier input unit 25 (see FIG. 7) of the browser 10. Here, if the input of the reproduction identifier is not accepted (NO in step S27), the process ends. On the other hand, when the input of the reproduction identifier is accepted (YES in step S27), the process proceeds to step S28.

In step S28, the reproduction information specifying unit 44 specifies the reproduction information stored in the reproduction information storage unit 33 in association with the reproduction identifier received by the reproduction identifier reception unit 43.

In the next step S29, the display mode reproduction unit 45 reproduces the display mode of the screen based on the reproduction information specified by the reproduction information specifying unit 44. For example, the screen output unit 34 controls the display mode of the browser 10 displayed on the display 5 of the user terminal 3 based on the display mode reproduced by the display mode reproduction unit 45. Then, the process ends.
