Disclosure of the Invention

Problems to be Solved by the Invention

[0004] However, the invention described in Patent Document 1 does not disclose a specific method for how to confirm whether a floor plan fits into the land.

[0005] However, in paragraph

[0011] of Patent Document 1, it is only described that first, the user's land is displayed on the display part of the user's terminal, and then the floor plan selected by the user is placed on the land. Therefore, it is understood that only the figure of the floor plan is superimposed on the figure of the land.

[0006] If that's the case, then for example, if the shape of the land is horizontally elongated and the shape of the floor plan is also horizontally elongated and roughly similar, then we only need to consider the size of the shapes, and if the area of ​​the floor plan is smaller than the area of ​​the land, then the floor plan will fit within the shape of the land, so there is no problem.

[0007] On the other hand, even if the size of the land plot and the size of the floor plan (building) are the same, if the land plot is saved in a "vertically elongated" format, it may be determined that a horizontally elongated building plot will not fit within it. In that case, it would be problematic because users would not be given the opportunity to access such floor plans.

[0008] Therefore, in view of these circumstances, the present invention aims to determine whether or not there is an arrangement in which the land figure and the building figure are contained within the land figure, rather than making a determination based solely on the superimposition of the land figure and the building figure. [Means for solving the problem]

[0009] To solve the above problems, the real estate simulation server device of the present invention is A first receiving means that receives land information from the user, including the size and shape of the land, A second receiving means for receiving building information, including the number of floors and rooms of the building that the user wishes to construct, A selection means that, based on the land information and building information received by the first and second receiving means, selects a suitable building by referring to a storage medium that stores at least floor plan information including the building's external dimensions, Movement control means for moving the building selected by the selection means while superimposing the figure of the building's floor plan information and the figure indicating the size and shape of the land included in the land information, A determination means for determining whether the figure of the plan information fits within the figure representing the shape of the land moved by the movement control means, A reply means that returns specific information that allows for the identification of a building that has been determined by the determination means to fit within the shape of the land in the plan view information, It is equipped with.

[0010] The selection means is, A first filtering means that filters the building floor plan information stored in the storage medium based on the building area and total floor area on the land, A second filtering means for filtering the building floor plan information stored in the storage medium based on the size of the land, It can have.

[0011] Furthermore, the real estate simulation system of the present invention is The above-mentioned real estate simulation server device, A client device comprising: a transmission means for transmitting the land information and the building information to the real estate simulation server device; and a receiving means for receiving the specific information returned from the real estate simulation server device, They are connected via a network.

[0012] Furthermore, the client device is An input screen display means that displays an input screen for inputting land information and building information transmitted by the aforementioned transmission means, The invention may also include an overlay screen display means that displays the plan view included in the specific information received by the receiving means superimposed on a figure showing the shape of the land included in the land information.

[0013] Embodiments of the present invention will be described below with reference to the drawings.

[0014] Figure 1 is a schematic diagram of a real estate simulation system according to an embodiment of the present invention. Figure 1 shows a real estate simulation server device 100, a client device 200, a storage medium 300, and a network 400, which will be described below.

[0015] The real estate simulation server device 100 is managed by a service provider of the real estate simulation system of the present embodiment. The real estate simulation server device 100 can use, for example, a server-type computer.

[0016] The real estate simulation server device 100 mainly receives land information and building information transmitted from the client device 200 via the network 400, and provides a floor plan of a building that can match them.

[0017] The land information in this specification refers to information including at least the size and shape of the land that a user operating the client device 200 is considering purchasing. Further, when more detailed information about the building is desired, information such as the building coverage ratio and floor area ratio related to the land can also be included as land information.

[0018] The building information in this specification refers to information including at least the number of floors and the number of rooms of the building that the user wishes to construct. Further, when more detailed information about the building is desired, information such as the orientation of the rooms, the size of the garden and the car space can also be included as building information (note that the building coverage ratio and floor area ratio may be positioned as building information).

[0019] Also, the floor plan included in the specific information that can identify the building provided by the real estate simulation server device 100 may be a sketch showing the outer shape of the building or a floor plan showing the size and arrangement of each room in the building. The former is suitable when it is desired to have a general image of the buildings that can be constructed on a specific piece of land, and the latter is suitable when it is desired to have a more detailed image up to inside the building. In the present embodiment, both of these can be displayed, but only one of them may be displayed.

[0020] The client device 200 is operated by a user who is considering purchasing land. The client device 200 is a general term for, for example, a personal computer, a tablet device, a PDA, a smartphone, a mobile phone, etc. The client device 200 is not limited to these as long as it has a computing function and a communication function, but it is necessary to have a display or to be connected to a display.

[0021] The client device 200 mainly transmits land information and building information via the network 400, receives the specific information that is returned from the client device 200 in response thereto, and displays it on an attached display.

[0022] The storage medium 300 stores at least floor plan information including the external dimensions of a building, which was created in the past by a service provider or a house builder of the real estate simulation system of the present embodiment. In the present embodiment, the floor plan information is stored in association with the "price", "floor area", "number of rooms", and "number of floors" of the building. Although FIG. 1 shows an example in which the storage medium 300 is a single device, it may be incorporated in the real estate simulation server device 100, for example, or may be realized by a plurality of devices.

[0023] The network 400 is a general term for various networks such as the Internet and a mobile phone network. The network 400 shall also include wireless networks such as Wi-Fi and Bluetooth, and locally provided local area networks.

[0024] FIG. 2 is a schematic diagram of the real estate simulation server device 100 shown in FIG. 1. FIG. 2 shows a first reception means 110, a second reception means 120, a selection means 130, a movement control means 140, a determination means 150, and a reply means 160, which will be described below.

[0025] The first receiving means 110 receives land information transmitted from the client device 200 via the network 400. The second receiving means 120 receives building information transmitted from the client device 200 via the network 400. The first and second receiving means 110 and 120 are treated as separate means because the objects they receive are conceptually different, but they may be implemented as a single means.

[0026] The selection means 130 selects a building that matches the land information and building information received by the first and second receiving means 110 and 120 from the storage medium 300, which stores at least floor plan information including the building's external dimensions. A specific example of building selection by the selection means 130 will be described later along with the operation of the real estate simulation system.

[0027] The movement control means 140 moves the building while superimposing the geometric shape of the building's floor plan information selected by the selection means 130 and the geometric shape indicating the size and shape of the land included in the land information received by the first receiving means 110.

[0028] The determination means 150 determines whether the figure of the plan information fits within the figure representing the shape of the land moved by the movement control means 140. If the determination result shows that the figure of the plan information fits within the figure representing the shape of the land, the plan information becomes subject to reply by the reply means 160; otherwise, the plan information does not become subject to reply by the reply means 160.

[0029] The reply means 160 sends back the specific information, which the determination means 150 has determined to contain the figure of the plan view information within the figure representing the shape of the land, to the client device 200 via the network 400.

[0030] Furthermore, the selection means 130 includes a first filter means 132 and a second filter means 134, which are described below.

[0031] The first filtering means 132 filters the building floor plan information stored in the storage medium 300 based, for example, the building area and total floor area of ​​the land received by the first receiving means 110 and the building information received by the second receiving means 120.

[0032] The second filtering means 134 filters the building floor plan information stored in the storage medium 300 based, for example, on the size of the land included in the land information received by the first receiving means 110.

[0033] Figure 3 is a schematic diagram of the client device 200 shown in Figure 1. Figure 3 shows the transmission means 210, the receiving means 220, the input screen display means 230, and the superimposed screen display means 240, which will be described below.

[0034] The transmission means 210 transmits land information and building information entered through the input screen displayed by the input screen display means 230 to the real estate simulation server device 100 via the network 400.

[0035] The receiving means 220 receives the specific information that is returned from the real estate simulation server device 100 via the network 400.

[0036] The input screen display means 230 displays on the display an input screen for inputting land information and building information transmitted by the transmission means 210. The input screen display means 230, for example, uses the functions of a web browser to access the relevant web server, download the information of the web page containing the input screen stored there, and display it on the display.

[0037] The superimposed screen display means 240 displays on an attached display a building floor plan superimposed on a figure showing the shape of the land included in the land information, which is included in the specific information received by the receiving means 220. The superimposed screen display means 240 can download information from a web page, including a superimposed screen web page, and display it on the display using the same method as the input screen display means 230.

[0038] Figures 4(a) and 4(b) show examples of input screens displayed on the display of the client device 200 shown in Figure 3. A service provider of a real estate simulation system can prepare a web page containing these input screens, store it on a designated web server, and use the web browser function of the client device 200 to access the web server, retrieve the information from the web page, and display it on the display.

[0039] Figure 4(a) shows an input screen 230A for the user to input land information about a plot of land they are considering purchasing. Figure 4(a) shows a land shape input area 231A with grid lines extending in the matrix direction, a selection area 232A for selecting the scale of the spacing between the grid lines, and a completion button display area 233A that the user presses after performing operations on the land shape input area 231A and the selection area 232A.

[0040] Figure 4(a) shows an example where the shape of a plot of land that the user is considering purchasing is drawn in the land shape input area 231A, and its size is specified. The land shown as an example here is a rectangle with dimensions of 10,000 mm in the vertical direction and 13,000 mm in the horizontal direction of the drawing, with a small portion missing in the upper right corner.

[0041] The method of inputting the land shape into the land shape input area 231A is not restricted; for example, it could be done by clicking on a corner, drawing a line, importing scanned data, or importing information from a webpage that lists the land for sale.

[0042] Figure 4(b) shows an example input screen 230B for the user to input building information about the building they wish to construct, which is accessed when the "Complete" button in the "Complete" button display area 233A of Figure 4(a) is pressed.

[0043] Figure 4(b) shows a selection area 231B for selecting one of several pieces of land information when multiple pieces of land information have already been entered through the input screen 230A shown in Figure 4(a), specification areas 232B and 233B for specifying the number of floors and rooms in a building, input areas 234B and 235B for entering the building area and total floor area, a selection area 236B for selecting the display order of the search results, and an apply button display area 237B which is pressed by the user after operations on the selection areas 231B and 236B, specification areas 232B to 233B, and input areas 234B and 235B.

[0044] For the number of floors and rooms of buildings related to designated areas 232B and 233B, an option for "not specified" is also provided, and if this is selected, building information of "not specified" can be sent to the real estate simulation server device 100. In addition, the building coverage ratio and floor area ratio may be entered and sent in place of, or together with, the building area and total floor area of ​​buildings related to input areas 234B and 235B.

[0045] Figure 5 shows an example of an overlay screen 240A displayed on the display attached to the client device 200 shown in Figure 3. Figure 5 shows the building management number assigned by the service provider of the real estate simulation system of this embodiment (e.g., "No. 561"), the building cost required for the construction of the building (e.g., "12.45 million yen"), and the total floor area (e.g., "75.7 m²"). 2 The property size (22.9 tsubo) is indicated along with information such as the number of rooms (e.g., "2LDK") and the number of floors (e.g., "3-story building").

[0046] Referring to Figure 5, a specific example of an overlaid screen, 240A, will be explained. In the overlaid image display area 241A, the figure 242A showing the shape of the land shown in Figure 4(a) is superimposed with the figure 243A of a floor plan of a building that may fit on that land. Here, the dimensions of the land are also indicated for figure 242A.

[0047] Furthermore, the dimensions do not need to be shown down to the smallest details, such as the example "8,000" mm or "7,000" mm. Conversely, the missing portion in the upper right corner may also be shown as "4,500" mm or "3,000" mm, or even as an approximate dimension of "5,400" mm for the slanted portion of that section. This also applies to the external dimensions noted on floor plans such as 244A, which will be explained below.

[0048] Floor plan 244A shows the layout of the first floor of this building. In this example, the arrangement, shape, and size of the private rooms, storage rooms, storage spaces, entrance hall, and hallway are shown along with their respective area measurements (in tatami mats). Floor plan 244A also includes the building's exterior dimensions.

[0049] Floor plan 245B shows the layout of the second floor, corresponding to floor plan 244A, and floor plan 246B shows the layout of the third floor, corresponding to floor plan 244A. The superimposed screen example 240A may also display the front, side, and rear views of the building.

[0050] Figure 6 is an explanatory diagram of the processes performed by the movement control means 140 and the determination means 150 of the real estate simulation server device 100 shown in Figure 2.

[0051] First, let's explain the premise of this process. Figure 6(A) shows an example of land shape 242C, which is a direct copy of the one shown in Figure 5, etc. Figure 6(B) shows an example of building shape 243C, which is a sketch of a rectangle with dimensions of 10,000 mm in the vertical direction and 9,500 mm in the horizontal direction, with a rectangle missing from the upper right portion, which has dimensions of 4,800 mm in the vertical direction and 3,500 mm in the horizontal direction.

[0052] Figures 6(a) to 6(f) show the process of moving the building figure 243C in Figure 6(B) onto the land figure 242C in Figure 6(A) to determine whether the building figure 243C fits within the land figure 242C.

[0053] In this specification, "fitting in place" means being able to build in accordance with Article 234, Paragraph 1 of the Civil Code, which stipulates that a distance of 50 cm or more must be maintained from the boundary line of the adjacent property. However, if there is a custom that differs from that provision, it may also be interpreted as being able to build in accordance with Article 236 of the Civil Code, which stipulates that the building must be able to be built in accordance with that custom.

[0054] First, an example of the processing procedure by the movement control means 140 and the determination means 150 will be described.

[0055] (1) The movement control means 140 determines the centroids of the land figure 242C and the building figure 243C, and moves the building figure 243C relative to the land figure 242C so that they coincide, and the determination means 150 determines whether or not the building figure 243C fits within the land figure 242C.

[0056] (2) If the determination result shows that the building figure 243C does not fit within the land figure 242C, the movement control means 140 moves the building figure 243C in parallel so that the overlapping area between the land figure 242C and the building figure 243C increases, and the determination means 150 successively determines whether or not the building figure 243C fits within the land figure 242C.

[0057] (3) If the building figure 243C does not fit into the land figure 242C even after translation, the movement control means 140 rotates the building figure 243C, and the determination means 150 successively determines whether or not the building figure 243C fits into the land figure 242C.

[0058] (4) If the building figure 243C does not fit into the land figure 242C even after rotation, the movement control means 140 reverses the building figure 243C, and further, while appropriately incorporating translation and rotation, the determination means 150 successively determines whether or not the building figure 243C fits into the land figure 242C.

[0059] The determination means 150 determines that if the building figure 243C moved by the movement control means 140 fits within the land figure 242C, the land figure 242C will be included in the building identification information sent back to the client device 200; otherwise, it will not be included in the identification information.

[0060] Figure 6(a) shows the state after the movement control means 140 moves the building figure 243C in Figure 6(B) in parallel to the land figure 242C in Figure 6(A), and the processes (1) and (2) described above are executed. In the example shown in Figure 6(a), a distance of 50 cm or more cannot be maintained from the adjacent property boundary line, so the determination means 150 determines that the building figure 243C does not fit within the land figure 242C.

[0061] Furthermore, according to the method described in Patent Document 1, it is presumed that at this stage, the building corresponding to the building figure 243C will be treated as not fitting within the land corresponding to the land figure 242C.

[0062] Figures 6(b) to 6(e) show the state after the processes (1) to (3) above have been performed, by the movement control means 140 rotating the building figure 243C in Figure 6(B) counterclockwise by 90 degrees, then approximately 135 degrees, then approximately 45 degrees, and then approximately 135 degrees relative to the land figure 242C in Figure 6(A). In the example shown in Figures 6(b) to 6(e), the determination means 150 will determine that the building figure 243C does not fit within the land figure 242C.

[0063] Figure 6(f) shows the state after the processes (1) to (4) above have been executed by the movement control means 140, which translates the building figure 243C in Figure 6(B) directly relative to the land figure 242C in Figure 6(A). In Figure 6(f), unlike the previous processes, the building figure 243C has been moved in reverse, and the building related to the building figure 243C is able to maintain a distance of 50 cm or more from the adjacent land boundary line related to the land figure 242C (1 square is 100 cm). Therefore, the determination means 150 determines that the building figure 243C is contained within the land figure 242C.

[0064] Figure 7 is a flowchart illustrating the operation of the real estate simulation system shown in Figure 1. Here, it is assumed that the input screen described using Figure 4 is stored on a web server (not shown).

[0065] First, when a user considering purchasing land operates the client device 200, the input screen display means 230 accesses the web server using its browser function, obtains the input screen shown in Figure 4(a), and displays it on the attached display (step S1).

[0066] Next, the user operates the client device 200 to input the desired land information into the land shape input area 231A on the input screen 230A shown in Figure 4(a), select the scale in the selection area 232A, and press the complete button display area 233A, which will transition to the input screen 230B shown in Figure 4(b).

[0067] Subsequently, the user operates the client device 200 to specify the number of floors and rooms of the building through the designated areas 232B and 233B shown in Figure 4(b), input the building area and total floor area of ​​the building through the input areas 234B and 235B, select the display order of the search results through the selection area 236B, and press the apply button display area 237B. At this point, the transmission means 210 transmits the land information entered through the input screen 230A and the building information entered through the input screen 230B to the real estate simulation server device 100 via the network 400 (step S2).

[0068] Here, an example was described in which the client device 200 transmits land information and building information together. However, for example, the land information may be transmitted when the user presses the complete button display area 233A, and the building information may be transmitted when the user presses the apply button display area 237B.

[0069] In the real estate simulation server device 100, when land information and building information transmitted from the client device 200 via the network 400 are received by the first and second receiving means 110 and 120, respectively, the first filtering means 132 in the selection means 130 outputs the number of floors and rooms of the building, the building area and total floor area included in that information to the storage medium 300 (step S3). The storage medium 300 then filters the building floor plan information that can match these, and outputs the matching floor plan information as the first filtering result (step S4).

[0070] Next, the second filtering means 134 in the selection means 130 outputs the size of the land included in the land information to the storage medium 300 (step S3), the storage medium 300 filters the building floor plan information that may match it, and the storage medium 300 outputs the matching floor plan information as the second filtering result (step S4).

[0071] Here, we have described a method in which the real estate simulation server device 100 separately acquires the first and second filtering results. However, it is also possible to acquire a single filtering result by outputting the information to be output in steps S3 and S5 in a single step.

[0072] However, as shown in Figure 7, if filtering results are obtained separately and building identification information based on each filtering result is provided to the user separately, there is an advantage in that, for example, users who have not yet progressed in the land selection stage can be given less restrictive information.

[0073] Whether to provide building identification information based on separate filtering results or building identification information based on a single filtering result can be, for example, left to the user's choice. In that case, the specific response could be determined by whether or not the "Specify Land" selection box displayed attached to the selection area 231B shown in Figure 4(b) is checked.

[0074] Regardless of which configuration is adopted, in the real estate simulation server device 100, once the selection means 130 selects building floor plan information that can match the land information and building information based on the filtering results, the movement control means 140 and determination means 150 can appropriately perform translation, rotation, and inversion movements on the selected floor plan information, as explained with reference to Figure 6, and then make a determination (steps S7, S8).

[0075] Then, the real estate simulation server device 100 sends back building identification information, including the building identification information that the determination means 150 has finally determined to be a target for reply, to the client device 200 via the network 400 using the reply means 160 in the manner shown in Figure 4(b) (step S9).

[0076] Therefore, the client device 200 can receive building identification information appropriately determined by the receiving means 220 and display it on the display using the superimposed screen display means 240. [Brief explanation of the drawing]
