  In the design of a relatively large scale solar power generation facility, when calculating the amount of solar radiation for each point, the amount of calculation increases as the number of points increases. When designing the arrangement of solar panels, the user may consider not only the amount of solar radiation but also whether it can be physically installed or whether construction is easy. However, when a large-scale photovoltaic power generation facility is represented by a three-dimensional model, there is a problem that the amount of data handled increases.

At this time, for example, based on the display priority set for the three-dimensional model of the solar panel so that the amount of data to be processed is equal to or less than a predetermined threshold, a partial model with a low priority is drawn. Omitted. For example, when the entire designed photovoltaic power generation facility is displayed in a wide area, the number of solar panels to be displayed increases and the amount of data to be handled increases. In such a case, for example, by displaying only the outline of the panel and the center line of the column of the gantry with the highest priority set, the amount of data to be processed is reduced, and the entire 3D model is quickly displayed. To be displayed. In addition, the threshold value mentioned above can be appropriately set according to the performance of the design support apparatus.

<Design process>
FIG. 2 is a process flow diagram illustrating an example of a design process executed by the design support apparatus 10. The model management unit 31 of the design support apparatus 10 receives the position information including the latitude and longitude of the site and the map information of the site, and stores them in the storage device 2 (FIG. 2: S1). In this step, the model management unit 31 receives an operation from a user, for example, and stores a coordinate value of a reference point such as a triangular point in association with a geodetic survey map, a satellite image, or the like. Note that the coordinate value may further include information representing the altitude.

  FIG. 3 is a diagram illustrating an example of map information. The map information 101 shown in FIG. 3 is an image representing the landform of the site. An image as shown in FIG. 3 is stored together with position information of a predetermined point in the image.

  In addition, the model management unit 31 receives the input of the three-dimensional information of the site indicated by the map information and stores it in the storage device 2 (FIG. 2: S2). In this step, the model management unit 31 stores, for example, a three-dimensional model representing the three-dimensional shape of the site where the map information is registered in S1 in response to an operation from the user. At this time, map information may be aligned and mapped to the three-dimensional model on the basis of a triangular point or the like.

  FIG. 4 is a schematic diagram for explaining a three-dimensional model of the site. In FIG. 4, the three-dimensional model 102 of the site is displayed on the map information 101 in alignment with the map information 101 registered in S <b> 1. The three-dimensional model may be modeled based on a geodetic survey map or the like, or may be created using a three-dimensional scanner or the like that calculates the position of an object using reflected laser light. May be.

  In addition, the model management unit 31 receives input of information representing the site attribute indicated by the map information 101 and stores it in the storage device 2 (FIG. 2: S3). In this step, the model management unit 31 configures the site at least such as information indicating the inclination direction of the site, information indicating the inclination angle of the site, information indicating the nature reserve, information indicating the well-known buried cultural property embedment area, etc. Information representing the attribute of the area is stored in the storage device 2 for some areas. Information registered in this step is also stored in association with position information on the map.

  FIG. 5 is a diagram illustrating an example of information indicating the inclination direction of the site. The inclination direction is an attribute of the site indicating the direction in which the inclination angle descending from each point is the largest, and is classified into, for example, the closest direction among eight divided directions. The number of orientation divisions can be set as appropriate. The information 103 indicating the inclination direction of FIG. 5 includes information for specifying the boundary of the continuous area where the inclination direction of the site is the same, and information indicating the inclination direction of each area. For example, any direction of north, northeast, east, southeast, south, southwest, west, and northwest is set for a certain region. The information for specifying the boundary of the region may be data of a coordinate group connected by a straight line, or may be data of a curve defined by a Bezier curve or the like.

  FIG. 6 is a diagram illustrating an example of information indicating the inclination angle of the site. The inclination angle is an attribute of the site representing the magnitude of the inclination at each point on the basis of the horizontal, and is represented by an elevation angle or a depression angle. The inclination angle may be classified into a range of angles having a predetermined width. The information 104 indicating the inclination angle in FIG. 6 includes information for specifying a boundary between continuous areas having the same inclination angle of the site and information indicating the inclination angle of each area.

  In addition, information indicating nature reserves, information indicating well-known reserves of buried cultural properties (not shown) includes information for identifying the boundaries of at least a part of the map, and protected areas and reserves. Information indicating the attribute of the area. Information indicating other attributes may be further stored, and at least a part of the information indicating the attributes described above may not necessarily be stored.

  The information indicating the site attributes as described above can be displayed by superimposing an area corresponding to some condition on the map, or extracting an overlapping area by combining information indicating a plurality of attributes.

  Moreover, the model management part 31 receives the input of the positional information on the solar panel arrange | positioned in a site, and makes the memory | storage device 2 hold | maintain the information which shows the position and inclination direction of a solar panel (FIG. 2: S4). In this step, the three-dimensional model of the solar panel is arranged on the three-dimensional model of the site in the virtual space. In the present embodiment, the design support device 10 creates the design data by arranging the solar panels displayed at the full size in the virtual space whose position is specified by the latitude and longitude. Construction can be done on site based on design data.

  FIG. 7 is a diagram illustrating an example of a screen on which a solar panel is arranged in a plan view of a three-dimensional model viewed from above. In the example of FIG. 7, a plurality of three-dimensional models 105 of solar panels are arranged so as to be superimposed on the three-dimensional model of the site where the map information 101 is mapped. The user can arrange an arbitrary number of solar panels at arbitrary positions.

  8 and 9 are diagrams for explaining information stored in the storage device 2 in the design process and displayed when designing the photovoltaic power generation facility. In the present embodiment, the map information 101 is mapped to the three-dimensional model 102 of the site, or registered on the plan view. Information indicating attributes such as information 103 indicating the inclination direction and information 104 indicating the inclination angle is also mapped to the three-dimensional model 102 of the site or registered and registered on the plan view. Further, a three-dimensional model 105 of the solar panel is arranged on the three-dimensional model 102 of the site. The three-dimensional model 105 of the solar panel is arranged above the three-dimensional model 102 of the site on a plan view as shown in FIG. 7, for example. Then, as shown by the dashed-dotted arrow in FIG. 8, the solar panel 3D model 105 is placed so that the lower end of the support of the solar panel 3D model 105 is buried in the ground surface of the site 3D model 102. Change the placement height. Further, the position and orientation of the solar panel can be individually changed by the user.

  In the present embodiment, the user can change the display method of the three-dimensional model or the like when adjusting the arrangement and orientation of the solar panels in S4 of FIG. Specifically, the information shown in FIGS. 8 and 9 is stored in different layers, and is switched between display and non-display based on a user instruction, or displayed and non-display based on the enlargement ratio of the three-dimensional model. The display can be switched.

For example, in S4, the information indicating the site attribute may be further used to display the area corresponding to the range in the predetermined inclination direction and the predetermined inclination angle in distinction from the other areas. For example, the display can be highlighted by changing the display color of an area where the inclination direction is southwest, south, or southeast and the inclination angle is 20 degrees or less, or by drawing the boundary of the area. In this way, when the user arranges the solar panel, it is possible to identify the direction of the slope with good power generation efficiency and the location where the inclination is not difficult to perform construction and maintenance. It can be used as a reference when deciding where to place. Moreover, you may make it calculate the electric power generation amount in the arbitrary periods of the design solar power generation facility using the existing simulation technique. For example, if the power generation amount desired by the user cannot be obtained as a result of the simulation, the user can further display an area to be displayed such as an area where the inclination direction is east or west or an area where the inclination angle is 22 degrees or less. You can expand the conditions and study the installation location of the solar panel.

  In addition, some areas include protected areas where development is restricted to protect ecosystems, etc., and buried places such as ruins. In such a case, when the user arranges the solar panels, information representing a nature reserve or information representing a buried cultural property-embedded area may be displayed superimposed on the three-dimensional model of the site. .

  FIG. 10 is a diagram for explaining display priorities set for the constituent elements of the solar panel. FIG. 10 shows sunlight in which components drawn and displayed increase or decrease in stages between a wide area display in which a relatively wide area is displayed on a display device and a detailed display in which a part of the site is enlarged. The panel is shown schematically. The upper diagram shows a simple three-dimensional model of the solar panel 200 drawn when the site is displayed in a wide area at the first magnification. In this example, only the outline 201 on the outside of the plurality of panels supported by the gantry and the center line of the column 202 included in the gantry are drawn. The middle diagram is a three-dimensional model at an intermediate stage drawn when the display of the site is enlarged to the second enlargement ratio. In this example, in addition to the upper drawing, fine outlines of the plurality of panels 2011 installed on the gantry, the thickness of the column 202, and the gantry 203 of the gantry are further drawn. Further, the lower diagram is a three-dimensional model drawn when the image is further enlarged to the third enlargement ratio. In the lower drawing, only a part of the panel 2011 is shown for convenience. In the lower figure, at least the thickness of the panel 2011 is displayed. In this way, it is possible to present to the user information for determining whether to interfere with the ground or a more accurate shadow shape. Further, as shown in the lower drawing, the gantry may include a receiving bar 204 provided at the top of the support column 202, a rail member 205 or the like spanned on the receiving bar 204, and the like. At this time, the wand 203 connects the support column 202 and the receiving bar 204.

  Among the components of the solar panel, the components that are drawn in the wide area display shown in the upper part of FIG. 10 have higher display priority, and the components that are drawn for the first time in the detailed display shown in the lower part are displayed. It can be said that the priority is low. In general, when a site is displayed in a wide area, the number of solar panels displayed on the screen increases, so that the amount of data to be processed increases. In the present embodiment, the amount of data to be processed can be adjusted by hiding a part of the three-dimensional model. For example, the data amount of the three-dimensional model to be read out on the memory may be determined in advance, and the three-dimensional model of the solar panel may be read out based on the above priority order so as to be within the determined data amount. . Many solar power generation facilities are larger than general buildings, but if the amount of data handled is controlled in this way, drawing and display of 3D models within the range that can be processed by the user's computer is possible. It can be carried out. In addition, the user can enlarge the display of the three-dimensional model as appropriate to check the details, change the location where the solar panel is disposed, ) Can be changed. Thus, the user can enlarge a three-dimensional model, for example, or can look down on the whole photovoltaic power generation facility with a top view or the like.

  FIG. 11 is a process flowchart showing an example of the display change process executed in S4 of FIG. When the design support apparatus 10 receives an operation of arranging a solar panel on the virtual space from the user, the design support apparatus 10 performs a display change process as shown in FIG. In the display change process, the display control unit 32 of the design support apparatus 10 displays information to be displayed on the display device in accordance with a display / non-display switching instruction by a user operation, an enlargement ratio of the three-dimensional model to be displayed, and the like. change. Further, the sunshine prediction unit 33 of the design support apparatus 10 simulates the state of sunshine at a predetermined date and time, and draws the shape of the shadow generated on the site.

  First, the display control unit 32 reads out information on the date and time for simulating the three-dimensional model to be displayed and sunshine (FIG. 11: S11). In this step, the display control unit 32 reads information registered in the storage device 2 by the design process of FIG. Moreover, the display control part 32 receives an input from a user, for example, and acquires the date information. On the date for simulating sunshine, options such as a winter solstice with a short sunshine time or a summer solstice with a long sunshine time may be presented in advance so that the user can select.

  Moreover, the display control part 32 draws a three-dimensional model according to the expansion rate of the site displayed on a display apparatus (S12). In this embodiment, the three-dimensional model of the solar panel is assumed to have a priority order for displaying the three-dimensional model for each component. In S12, for example, when displaying the entire photovoltaic power generation facility in a bird's-eye view, for each solar panel, only a partial model representing a rough outline is drawn, and the details of the solar panel are displayed. In the case of displaying an enlarged image, a partial model representing the details of the solar panel is further drawn.

  Also, the sunshine prediction unit 33 calculates the state of sunshine at the date and time acquired in S11, and draws the shape of the shadow generated on the site (FIG. 11: S13). In this step, using the existing technology, the place indicated by the location information of the site and the sunshine state at a predetermined date and time are simulated, and a shadow is drawn on the three-dimensional model. At this time, it is possible to change the sunshine state to be displayed by passing the simulation time at an arbitrary speed, or to stop the passage of the simulation time and check the sunshine state at various points at a certain date and time. You may be able to do it.

  Thereafter, the display control unit 32 determines whether the user has changed the display method of the three-dimensional model (S14). In this step, when the user changes the enlargement ratio of the design data or changes the viewpoint, it is determined that the display method has been changed. If it is determined that the display has been changed (S14: YES), the process returns to S12, and the three-dimensional model is redrawn based on the changed enlargement ratio and viewpoint.

  On the other hand, when it is determined that the display has not been changed (S14: NO), the display control unit 32 determines whether or not the simulation time has elapsed (S15). In the present embodiment, for example, it is assumed that whether or not to elapse time is set based on a user operation. If it is determined that the time has not elapsed (S15: NO), the process returns to S14 and the process is repeated. On the other hand, if it is determined that the time will elapse (S15: YES), the process returns to S13, and the shadow state after the elapse of time is redrawn.

<Effect>
In this embodiment, it is possible to adjust the amount of data to be processed by setting a priority order for a portion of the three-dimensional model and switching between display and non-display based on the enlargement ratio and priority of the three-dimensional model. it can. In this way, even when designing a large-scale photovoltaic power generation facility, design data can be drawn without stress for the user.

  In addition, information indicating various attributes of the site can be superimposed and displayed on the three-dimensional model of the site, and the user can support the solar panel placement work.

<Example>
FIG. 12 is a diagram illustrating an example of a three-dimensional model that overlooks the state of shadows that occur on a site at a certain date and time. In the example of FIG. 12, the shadow of the nearby land, the shadow due to the inclination of the installation surface of the solar panel, and the shadow of the solar panel mount appear. For example, by simulating the shape of a shadow generated in the site during the day of the winter solstice when the altitude of the sun is low, the user can visually recognize a solar panel with poor power generation efficiency.

  FIG. 13 is a diagram for explaining an example in which a three-dimensional model is enlarged and displayed. The portion surrounded by a circle in the upper image is not sufficient in height from the ground of the solar panel, and may interfere during construction. When the user finds such a portion, the inclination angle of the solar panel can be changed.

  FIG. 14 is a diagram illustrating an example of drawing information representing a passage on a three-dimensional model. The part surrounded by the ellipse is a part where the distance between the passage and the solar panel is long, and there is a possibility that construction and maintenance may be difficult. The user can check the design data by enlarging the three-dimensional model or changing the viewpoint.
