FIG. 1 is a schematic diagram showing an overall configuration of a plant management system (hereinafter, appropriately referred to as “system”) 1 according to at least one embodiment of the present invention.
The system 1 is a system that manages constituent elements or various types of information for a plant facility including various constituent elements such as a nuclear power plant, a thermal power plant, or a chemical plant. As shown in FIG. 1, the system 1 is configured by a main server 2, a database server 4, and a user terminal 6 being communicably connected to each other via a network 8.
The network 8 may be wired or wireless.

  In FIG. 1, an external database 10 connected via a network 8 is also shown as a configuration other than the system 1. The external database 10 is a database that stores various types of information used for other purposes, and the system 1 accesses the various types of information stored in the external database 10 via the network 8 to transfer existing information to the system 1. It is configured so that it can be appropriately applied to the control of.

(1-1. Main server configuration)
The main server 2 is a control unit that controls various processes performed by the system 1. Here, FIG. 2 is a block diagram functionally showing the internal configuration of the main server 2. As shown in FIG. 2, the main server 2 includes a receiving unit 12 that receives various types of data from another configuration via the network 8, and a processing unit 14 that performs a process according to an application program using the various types of received data. , A transmission unit 16 for transmitting the processing result to another configuration via the network 8. In particular, the processing unit 14 has a registration processing unit 18, an update processing unit 20, a search processing unit 22, and a measurement processing unit 24 for each processing control content described later.
The specific processing contents of the registration processing unit 18, the update processing unit 20, the search processing unit 22, and the measurement processing unit 24 included in the processing unit 14 will be described in detail later.

(1-2. Configuration of data server)
The database server 4 includes a database that stores various kinds of information related to plant management control, and particularly includes an image database 4a, a point cloud database 4b, and an attribute information database 4c in this embodiment. These databases are configured to be communicable via the network 8, and are configured to be appropriately readable and writable in response to a request from the main server 2 or the user terminal 6.

  The image database 4a stores various kinds of information including a plurality of image data regarding the plant to be managed. Specifically, the image data includes drawing data (for example, a sketch, design drawing, system diagram, and connection diagram) of the plant and photographic data (for example, a panoramic photograph taken over a wide area in the plant, the plant. Walk-through panoramic photographs and moving pictures taken while moving the viewpoint inside, photographs taken from a specific viewpoint in the plant, and focus photographs taken by focusing on specific components) are included.

  Here, a specific example of the image data stored in the image database 4a will be described with reference to FIGS. 3 and 4. FIG. 3 is a sketch showing the overall configuration of the plant to be managed, and FIG. 3 simply shows the layout of the main constituent elements within the plant site. Further, FIG. 4 is photographic data corresponding to the range A (area surrounded by a dotted line) in FIG. Thus, the sketch of FIG. 3 is associated with the image data corresponding to each range as shown in FIG. In particular, when the photographic data is displayed as shown in FIG. 4, the sketch of FIG. 3 is simply shown near the edge of the screen to improve the convenience for the user.

  Such various image data are stored in the image database 4a in a state where the mutual positional relationship is defined in advance. The relative positional relationship between the image data may be defined when the image data is acquired (for example, when taking a walk-through panoramic photograph and a focus photograph, at which position the focus photograph is taken when a walk-through is performed on a predetermined route. It is also possible to specify the viewpoint from which the image is to be taken) and to specify it afterwards by performing a calculation process after the image data is acquired. In this way, by predefining the relative positional relationship in the plurality of image data stored in the image database 4a, when associating with the point cloud data via the common three-dimensional coordinate system, the individual image data There is no need to associate each with, and management burden can be effectively reduced. In particular, even when image data includes many different styles such as still images and moving images, it is possible to associate the point cloud data with the point cloud data by predefining the relative positional relationship between these data. The burden does not increase.

  The point cloud database 4b stores point cloud data that defines the three-dimensional structure of the plant. The point cloud data is configured as a set of coordinate points that specify the structure of the plant in the three-dimensional coordinate system, and for example, the result acquired by three-dimensional laser measurement is used. FIG. 5 is an example of point cloud data corresponding to the photographic data of FIG.

As a concrete method for acquiring point cloud data, for example, a measurement process of installing a 3D color laser scanner device at a specific position and collecting color point cloud data of 360 degrees is repeated while moving within the plant. Point cloud data can be obtained at. The measurement of such point cloud data may be performed in parallel with the above-described image data capturing. In this case, since the relative positional relationship between the point cloud data and the imaging data can be uniformly ensured, it is possible to improve the work of confirming the consistency and reliability of each, and, as will be described later, each three-dimensional coordinate system. It is advantageous when commonizing.
The point cloud data may be displayed in monochrome, but may be displayed in color because the visibility of the user can be improved.

  The plurality of image data stored in the image database 4a and the point cloud data stored in the point cloud database 4b are associated with each other via a common three-dimensional coordinate system. Here, with reference to FIG. 6, a procedure for associating the separately acquired image data and the point cloud data with a common three-dimensional coordinate will be described. FIG. 6 is a flowchart showing a procedure for associating three-dimensional coordinates in image data and point cloud data.

First, a target that is commonly measured is extracted for both the image data and the point cloud data to be associated (step S001). Then, based on the position information of the extracted target, conversion into the same coordinate system (point group synthesis) is performed (step S002). After that, a point whose coordinate value in the common coordinate (plant) system can be discriminated is extracted on the point group (step S003), and the same coordinate value as the common coordinate system is given to that position, so that the common coordinate system Conversion is performed (step S004).
By thus associating the image data and the point cloud data via the common three-dimensional coordinate system, the corresponding point cloud data is referred to for any point on the image displayed based on the image data. As a result, the position in the accurate three-dimensional coordinate system can be specified.

Subsequently, the attribute information database 4c stores the attribute information about the constituent elements of the plant. As a specific example, the attribute information about the component "valve" used in the plant includes, for example, an identification number (ID) in the plant, a material, a valve number, a manufacturer, dimensions, a pressure value, a radiation pollution density, etc. As described above, various information defined in the plant system diagram is included.
When a nuclear power plant is a management target, the attribute information may include, for example, 3D model data (including shielding calculation attribute data), a radiation dose map, a survey form, and the like.

(1-3. Configuration of user terminal)
The user terminal 6 is a terminal operated by a user, and in FIG. 1, a user terminal 6a installed in an office that manages the plant and a user terminal 6b installed on the site of the plant are illustrated. There is. In particular, the user terminal 6b is configured as a mobile terminal that can be carried by a worker who works at the plant site.
In the specification of the present application, when the user terminals 6a and 6b are not distinguished from each other, the user terminal 6a and the user terminal 6b are collectively denoted by reference numeral "6".

  FIG. 7 is a block diagram functionally showing the internal configuration of the user terminal 6 of FIG. As shown in FIG. 7, the user terminal 6 includes a communication unit 26 for communicating via the network 8, an input unit 28 for inputting various information, a communication content of the communication unit 26, and an input unit 28. A processing unit 30 that performs various processes based on the input content, and an image display unit 32 that displays an image regarding the plant are provided. In particular, the image display unit 32 is configured to display an image based on an image signal received from the main server 2 via the network 8.

  On the image display unit 32, the image data and the point cloud data acquired from the image database and the point cloud database via the network 8 as described above can be displayed as an image. Specifically, as the image data, drawing data (for example, a sketch of a plant, a blueprint, a system diagram, and a wiring diagram) and photographic data (for example, a panoramic photograph taken over a wide range in the plant, the inside of the plant It is possible to display walk-through panoramic pictures / moving pictures taken while moving the viewpoint, pictures taken from a specific viewpoint within the plant, and focus pictures taken by focusing on specific components (FIGS. 3 and 4). See). On the other hand, as the point cloud data, the measurement result of the 3D color laser scanner device as shown in FIG. 5 is displayed.

With respect to the image data and the point cloud data displayed on the image display unit 32, when the predetermined position is designated on the display image by the operation of the input unit 28, the image display is moved to the corresponding position on the other display image. , Linked to each other. As a result, the display image can be smoothly transferred from one side to the other side between the image data and the point cloud data, and the convenience is improved so that the user can easily intuitively grasp the state in the plant on the display image. Has been planned.
Note that the user terminal 6 may ensure security by performing personal authentication during use.

(2. Plant management control)
Next, various processes performed by the system 1 having the above configuration will be described in detail. Here, registration processing, update processing, search processing, and measurement processing will be sequentially described as typical processing performed in the system 1.

(2-1. Registration process)
FIG. 8 is a flowchart showing the registration process performed by the system of FIG. 1 for each process. The registration process is a process of newly registering the attribute information regarding the constituent elements of the plant in the attribute information database 4c.

  In this process, first, the user operates the input unit 28 of the user terminal 6 to display an image in a desired pattern on the image display unit 32 (step S101). More specifically, when the user operates the input unit 28, the user terminal 6 creates an image display command corresponding to the input content in the processing unit 30, and sends the image display command from the communication unit 26 via the network 8. It is sent to the main server 2. The main server 2 acquires corresponding image data from the image database based on the received image display command, and transmits it to the user terminal 6 via the network 8. In the user terminal 6, the communication unit 26 acquires the image data from the main server 2 and the image display corresponding to the image data is performed.

  When a desired image is displayed on the image display unit 32 in this manner, the user further operates the input unit 28 to display a range in which a component for which attribute information is newly registered exists on the display image. Is selected (step S102). The range selected by the user is transmitted to the main server 2 via the network 8. The main server 2 calculates the three-dimensional position coordinates corresponding to the selected range by referring to the point cloud data associated with the display image (step S103).

  Then, the user further operates the input unit 28 to input the attribute information to be newly registered for the selected area in step S102 (step S104). The input attribute information is transmitted to the main server 2 via the network 8 and registered by the registration processing unit 18 in the attribute information database 4c in association with the three-dimensional position coordinates calculated in step S103 (step S105).

Subsequently, the registration processing unit 18 determines whether or not there is the same attribute information as the attribute information registered in step S105 by searching the attribute information database 4c (step S106). When the same attribute information exists (step S106: YES), the registration processing unit 18 links the attribute information registered in step S105 with the attribute information extracted in the search processing in step S106 (step S107). By linking and registering components having common attribute information in this way, when various processes such as update, addition, and deletion are performed on a specific component in the future, other linked configurations The same process is performed for the elements. As a result, even in a plant having a complicated configuration, it is possible to realize efficient management while reducing the work load.
On the other hand, if the same attribute information is not retrieved (step S106: NO), the registration processing unit 18 ends the process without performing step S107.

  In this way, in the registration processing, the attribute information is registered in association with the point cloud data corresponding to the range selected on the image, so that the attribute information can be efficiently managed even in a plant having a complicated configuration. It can be carried out. In addition, such a registration process can be realized by a simple operation of selecting a range corresponding to a component to be registered on the display image of the user terminal 6 and inputting attribute information to be registered, so that a wide range of users can use it. Can be used.

(2-2. Update process)
FIG. 9 is a flowchart showing the update process performed by the system of FIG. 1 for each process. The update process is a process of updating various data stored in the database server 4 by replacing the various data with new data.

  In this process, first, the user operates the input unit 28 of the user terminal 6 to display an image in a desired pattern on the image display unit 32, as in step S101 (step S201). Then, the user further operates the input unit 28 to select the image display range to be updated or the image display range corresponding to the attribute information to be updated on the display image (step S202). The selection of such an image display range is performed following step S102. Further, the user further operates the input unit 28 to input the update content (image data or point cloud data) in the range selected in step S202 (step S203).

  The range selected by the user and the updated content are transmitted to the main server 2 via the network 8. The main server 2 calculates the corresponding three-dimensional position coordinates by referring to the associated point cloud data for the display range selected in step 202 (step S204), and the update processing unit 20 performs the calculation. The registered contents corresponding to the three-dimensional position coordinates are updated to the input contents of step S203 (step S205). Specifically, when image data, point cloud data and attribute information are input as update data in step S203, the corresponding image data and point cloud from the image database 4a, point cloud database 4b and attribute information database 4c are input. The data and the attribute information are specified and updated.

Subsequently, the update processing unit 20 determines whether or not there is other information linked to the update content registered in step S205 by searching the database updated in step S205 (step S206). ). If there is other linked information (step S206: YES), the update processing unit 20 also reflects the update content in step S205 on the link destination (step S207). In this way, in the update process, when an update is performed on a specific element, the update content can be reflected on other elements linked to the element and registered. As a result, even in complex plant equipment, the updating process becomes efficient and the work load is reduced.
On the other hand, when there is no other linked information (step S206: NO), the update processing unit 20 ends the process without performing step S207.

  In this way, in the update process, when some kind of update is done to the existing plant, the user performs the update work by a simple operation of selecting the update location on the image and inputting the update content as update information. it can. The update information registered by such an operation is managed in association with the three-dimensional positional relationship of the selection range specified via the point cloud data, so that even a plant having a complicated configuration can be easily managed. .

(2-3. Search processing)
FIG. 10 is a flow chart showing the search process executed in the system of FIG. 1 for each process. The search process is a process of searching for data that matches a predetermined search condition from various data stored in the database server 4.

  First, the user inputs search conditions by operating the input unit 28 of the user terminal 6 (step S301). Here, the search condition includes various types of information included in the attribute information (for example, identification number (ID) of component to be searched, material, item number, manufacturer, size, pressure value, radiation contamination density, etc.). .

  The search condition input in step S301 is transmitted to the main server 2 via the network 8. The search processing unit 22 of the main server 2 searches the database server 4 based on the search condition, and specifies the constituent element corresponding to the search condition (step S302). Then, the search processing unit 22 creates display data for the specified component to display in a superimposed manner on the display image (step S303).

  The display data created in step S303 is transmitted to the user terminal 6 via the network 8 and displayed on the image display unit of the user terminal 6 (step S304). As a result, the components that match the search condition input in step S301 are displayed on the display image as markings on the image display unit. As a result, the user can easily understand where the constituent element that matches the search condition exists by the marking on the display image.

  As described above, in the search process, a database search is performed using the attribute information input by the input unit as a search condition, so that a component having the attribute information can be extracted. As a result, even in a plant having a complicated configuration, it is possible to easily grasp the component having the specific attribute information regardless of the level of the user.

(2-4. Measurement processing)
FIG. 11 is a flowchart showing the measurement process performed by the system of FIG. 1 for each process. The measurement process is a process of measuring the distance between any two points on the image displayed on the image display unit of the user terminal 6.

  In this process, first, the user operates the input unit 28 of the user terminal 6 to display an image in a desired pattern on the image display unit 32, as in step S101 (step S401). Then, the user further operates the input unit 28 to select two arbitrary points on the display image to be measured (step S402).

  The information regarding the measurement point selected in step S402 is transmitted to the main server 2 via the network 8. The measurement processing unit 24 of the main server 2 calculates the three-dimensional coordinates corresponding to the two received measurement points based on the point cloud data (step S403). Then, the measurement processing unit 24 calculates the distance between the two points by geometrical calculation from the three-dimensional coordinates of the two measurement points calculated in step S403 (step S404). The measurement result calculated in step S404 is transmitted to the user terminal 6 via the network 8 and displayed on the image display unit 32 to notify the user (step S405).

  As described above, in the measurement process, the distance between the two points designated on the image by the input unit 28 can be obtained by the coordinate calculation using the three-dimensional coordinate system corresponding to the point cloud data. Since the distance between the two points designated on the display image can be calculated in this way, the distance can be easily measured even when the user is away from the plant site, for example.

  As described above, according to the present embodiment, the image displayed on the image display unit 32 is associated with the point cloud data via the common three-dimensional coordinate system, and therefore, on the image selected by the user. A three-dimensional positional relationship can be easily obtained for a specific range. Therefore, even in a plant having a complicated configuration, the user can select the predetermined range on the image displayed on the image display unit 32 and input the attribute information corresponding to the range to set the attribute related to the intended component. Information can be easily managed. As described above, even a user who does not have much knowledge or experience about a plant can handle the plant by a simple operation of selecting a range on the display image.

  The present disclosure can be used for a plant management system that manages attribute information about plant components.
