Description

[Technical field]

[0001] The present disclosure relates to a design support system for designing electrical equipment of a building. [Background technology]

[0002] High-voltage power receiving equipment is installed in relatively large buildings. High-voltage power receiving equipment transforms the high-voltage electricity supplied by the power company into low-voltage electricity and distributes and supplies the electricity to each floor of the building. Electricity from the high-voltage power receiving equipment is supplied to each load via a distribution board installed in the building. The "load" here refers to, for example, air conditioners, lighting equipment, and outlets for connecting electrical equipment.

[0003] High-voltage power receiving equipment may be installed indoors in a building, or may be housed in a metal box and installed outdoors. Patent Document 1 below discloses a specific configuration of high-voltage power receiving equipment. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-96699 A Summary of the Invention [Problem to be solved by the invention]

[0005] When installing high-voltage power receiving equipment in a building, it is necessary to determine the specifications of the equipment in advance based on the power consumption of the load to be installed in the building, etc. "Specifications of high-voltage power receiving equipment" refers to, for example, the size and weight of the high-voltage power receiving equipment, the capacity of the transformer installed in the high-voltage power receiving equipment, etc.

[0006] The specifications for high-voltage power receiving equipment are often determined by the construction company that designs the building and the electrical equipment contractor that provides the high-voltage power receiving equipment, who exchange necessary information with each other. For example, the construction company first determines the load specifications and presents these specifications to the electrical equipment contractor. The electrical equipment contractor, who has been presented with the load specifications, determines the specifications for the high-voltage power receiving equipment required to supply power to the load and communicates these specifications to the construction company. The construction company, who has been informed of the specifications for the high-voltage power receiving equipment, designs the installation location of the high-voltage power receiving equipment, etc., based on the size of the high-voltage power receiving equipment, etc., indicated in the specifications.

[0007] However, when designing a building, changes to the load specifications and other factors are likely to occur frequently. When the load specifications change, the specifications of the high-voltage power receiving equipment must also be determined accordingly, which means that information is exchanged again between the builder and the electrical equipment contractor. For this reason, it often takes a relatively long time to finally determine the configuration of the electrical equipment, including the high-voltage power receiving equipment.

[0008] In order to solve the above problems, the present inventors have been studying a design support system for designing electrical equipment for buildings. The design support system makes it possible to automatically determine the specifications of high-voltage power receiving equipment based on the load specifications and other information input by the builder, and to present the specifications to the builder. This eliminates the need for the builder to wait for a response from the electrical equipment contractor, making it possible to design the electrical equipment for a building in a shorter time than before.

[0009] In the above-mentioned design support system, if a worker who inputs information about loads can intuitively input information while concretely imagining the distribution of loads on each floor of the building, input errors can be reduced. However, no specific consideration has been given to an interface that realizes such intuitive input operations.

[0010] An object of the present disclosure is to provide a design support system that enables intuitive input of information relating to loads to be installed in a building. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the present invention as recited in claim 1 is a design support system for designing electrical equipment of a building, comprising an input unit in which load information, which is information relating to the load installed in the building, is input in correspondence with a floor of the building, a display unit which displays the load information for all the floors collectively on one screen, and a determination unit which determines specifications of high-voltage power receiving equipment to be installed in the building based on the input load information. The invention as recited in claim 2 is the invention as recited in claim 1, characterized in that an add button for adding the load information is displayed on the display unit. The invention described in claim 3 is the invention described in claim 1 or 2, characterized in that the display unit can also display the load information divided for each floor of the building. Effect of the Invention

[0012] According to the present invention, a design support system can be provided that allows intuitive input of information about the loads to be installed in a building, by including an input unit in which load information, which is information about the loads installed in a building, is input in association with the floor of the building, a display unit that displays the load information for all floors on one screen, and a determination unit that determines the specifications of the high-voltage power receiving equipment to be installed in the building based on the input load information.

[0014] Hereinafter, the present embodiment will be described with reference to the accompanying drawings. Therefore, in each drawing, the same components are denoted by the same reference numerals as much as possible, and duplicate explanations are omitted.

[0015] The configuration of a design support system 10 according to this embodiment will be described with reference to FIG. 1. The design support system 10 is configured as a system for designing electrical equipment for a building. The multiple terminals 20 shown in FIG. 1 are computer devices used as interfaces when a user uses the design support system 10. Each terminal 20 is connected to the design support system 10 via a network system NW, and is capable of performing two-way communication with the design support system 10. From the perspective of a user operating the terminal 20, the design support system 10 is a server device installed on the cloud.

[0016] The terminal 20 may be a stationary computer device, or may be a mobile communication terminal carried by a user. The "user" envisioned here is, for example, a construction company that designs at least the layout of electrical equipment in a building. By accessing the design support system 10 via the terminal 20, the user can design the electrical equipment of the building with support from the design support system 10. A plurality of terminals 20 may be prepared as in the example of FIG. 1, or only one terminal 20 may be prepared.

[0017] The design support system 10 is configured as a system consisting of one or more computers. The design support system 10 includes an input unit 11, a display unit 12, a determination unit 13, a storage unit 14, and a communication unit 15 as elements expressed as functional blocks.

[0018] The input unit 11 is a section where load information is input via the terminal 20. "Load information" refers to information related to the load installed in a building. "Load" refers to, for example, air conditioners, lighting devices, and outlets for connecting electrical appliances. The form of the screen display that serves as an interface for receiving the input of load information, and the details of the input load information will be described later.

[0019] The display unit 12 is a part that performs processing for displaying the load information on the screen of the terminal 20. The manner in which the load information is displayed will be described later.

[0020] The determination unit 13 is a part that performs processing to determine the specifications of the high-voltage power receiving equipment to be installed in the building based on the load information input to the input unit 11. The determination unit 13 determines the specifications of the high-voltage power receiving equipment so as not to interfere with the power supply to the loads installed in the building. The high-voltage power receiving equipment is, for example, a cubicle installed outdoors the building. The "specifications" of the high-voltage power receiving equipment determined by the determination unit 13 include, for example, the capacity of the transformer installed in the high-voltage power receiving equipment (i.e., the maximum value of the power that can be output from the transformer), the size and weight of the high-voltage power receiving equipment, etc.

[0021] The storage unit 14 is a non-volatile storage device, such as a hard disk, provided in the design support system 10. The storage unit 14 stores various information related to the electrical equipment, including the above-mentioned load information input by a user via the terminal 20. The storage unit 14 also stores in advance information necessary for the calculation processing performed by the determination unit 13 and the like.

[0022] The communication unit 15 is a communication interface for realizing communication between the design support system 10 and the terminal 20. The network system NW connecting the communication unit 15 and each terminal 20 may be a wired communication network or a wireless communication network. The network system NW may be a public communication network used for multiple purposes such as the Internet, or may be a dedicated communication line provided for the design support system 10.

[0023] Prior to describing the function of the design support system 10, i.e., the function of supporting the design of the electrical equipment of a building, an overview of the "electrical equipment" of the building will be described. Figure 2 shows a schematic diagram of an example of a building in which electrical equipment is installed. The building 700 shown in Figure 2 is configured as a three-story building, and high-voltage power receiving equipment 710 is installed outdoors.

[0024] The high-voltage power receiving equipment 710 is equipment for transforming high-voltage power supplied from the power company's power transmission network TL into low-voltage power and distributing and supplying the power to each floor of the building 700. The high-voltage power receiving equipment 710 is provided with a transformer 711 for performing the above-mentioned transformation, a capacitor (not shown), and the like.

[0025] One or more distribution boards 720 are installed on each floor of the building 700. In the example of FIG. 2, two distribution boards 720 are installed on each floor, but the number of distribution boards 720 may be different. The high-voltage power receiving equipment 710 and each distribution board 720 are connected by a trunk line 740. Note that in FIG. 2, one trunk line 740 extending from the transformer 711 of the high-voltage power receiving equipment 710 is depicted as being branched into multiple lines midway and connected to each distribution board 720, but the trunk line 740 may be configured differently. For example, the high-voltage power receiving equipment 710 and the distribution board 720 may be connected by an individual trunk line 740 prepared for each distribution board 720.

[0026] In Fig. 2, the loads installed on each floor are depicted diagrammatically as blocks labeled with the reference numeral 730. Hereinafter, each load will also be referred to as "load 730." In the example of Fig. 2, it is depicted as if four loads 730 are installed on each floor, but the actual number of loads 730 may differ from this.

[0027] Each distribution board 720 distributes the power supplied from the trunk line 740 to each load 730. The distribution board 720 is provided with a main breaker 721 and branch breakers 722. The main breaker 721 and the branch breakers 722 are both circuit breakers, and are configured to automatically cut off the electric circuit when the value of the power passing through them exceeds a predetermined breaking capacity.

[0028] As is well known, the larger the capacity of the load 730 installed in the building 700, i.e., the larger the power consumption, the larger the interrupting capacity of the branch breaker 722 and the interrupting capacity of the main breaker 721 must be. Also, the larger the power consumed by the entire building 700, for example due to an increase in the number of loads 730, the larger the capacity of the transformer 711 must be. The design support system 10 has a function of automatically determining the specifications of the high-voltage power receiving equipment 710, including the capacity of the transformer 711, based on the "load information" input as information on the load 730. Therefore, the builder who designs the building 700 can obtain the specifications of the high-voltage power receiving equipment 710 simply by operating the design support system 10, without exchanging information with the electrical equipment contractor who provides the high-voltage power receiving equipment 710.

[0029] The following describes the functions of the design support system 10 while showing examples of screens displayed on the terminal 20. The design support system 10 according to this embodiment manages various information related to electrical equipment of multiple buildings 700 collectively for each building 700. A collection of information corresponding to one building 700 is stored in the storage unit 14 of the design support system 10 as "case information."

[0030] When a user logs in to the design support system 10 via the terminal 20, a case information screen 100 shown in Fig. 3 is displayed on the screen of the terminal 20. The case information screen 100 is composed of a case information registration section 110 in the upper section and a case list display section 120 in the lower section.

[0031] The case information registration section 110 is a section that the user operates to register new case information. The user inputs a name that identifies the case information, for example the name of the building 700, into the "subject" input field. In addition to the subject input field, the case information registration section 110 displays a floor number setting section 111, a register button 112, and a cancel button 113.

[0032] The floor number setting unit 111 is a section where the user inputs the number of floors of the building 700, that is, the number of floors. The user sets the top floor and the bottom floor of the building 700 in the floor number setting unit 111. If the building 700 is three stories tall as in the example of Figure 2, then "3" is input as the top floor and "1" is input as the bottom floor.

[0033] In addition to the above, the case information registration unit 110 displays many other input fields for inputting information related to the case, but individual explanations of these will be omitted. After inputting the necessary information, the user clicks the register button 112. This causes the input new case information to be sent to the design support system 10, where it is additionally registered and stored in the memory unit 14. If the cancel button 113 is clicked instead of the register button 112, the information input into each input field of the case information registration unit 110 is cleared.

[0034] The case list display section 120 displays a list display section 121, a load information input button 122, and a delete button 123.

[0035] The list display section 121 displays a list of case information that has been registered by the currently logged-in user. As described above, when the registration button 112 in the case information registration section 110 is clicked and new case information is additionally registered, a character string indicating that case information is added as a new line in the list display section 121. In the example of FIG. 3, three pieces of case information consisting of Case A, Case B, and Case C are displayed in the list display section 121. Note that the character strings displayed here, such as "Case A," are the names that were entered in the "Subject" field in the case information registration section 110.

[0036] The user can select the case information by clicking on the name of the case information displayed in the list display section 121. After selecting specific case information, if the user clicks on the delete button 123, the case information is deleted from the list display section 121 and also from the memory section 14.

[0037] After selecting specific project information displayed in list display section 121, when the user clicks load information input button 122, a product usage information screen 200 shown in Fig. 4 is displayed on the screen of terminal 20. Product usage information screen 200 is a screen on which load information of building 700 corresponding to the project information selected as described above is input. An example in which building 700 is a 10-story building will be described below.

[0038] The product information screen 200 displays floor frames 210 and board blocks 211. The floor frames 210 are frames drawn in a substantially rectangular shape, and the same number of floors as the number of floors of the building 700 are displayed lined up vertically. Each floor frame 210 corresponds to one of the floors of the building 700. The design support system 10 displays the same number of floor frames 210 as the number of floors of the building 700, based on the number of floors inputted in the floor number setting unit 111 of FIG. 3.

[0039] 4, only two floor frames 210, one corresponding to the 10th floor and the other corresponding to the 9th floor, are shown, but these are a part of the 10 floor frames 210. The user can display on the screen any of the floor frames 210 corresponding to each floor of the building 700 by operating the scroll bar on the right end. The number of floor frames 210 that can be displayed simultaneously may be different from two.

[0040] The panel block 211 is an icon indicating a panel installed on a floor of the building 700. The "panel" here refers to the distribution board 720 in the example of Fig. 2, but the panel block 211 may indicate a control panel or an equipment panel. Note that in Fig. 4, a character string such as "LP-10-01" written inside the panel block 211 is a symbol for identifying each panel, and is set arbitrarily by the user.

[0041] The board block 211 arranged inside each floor frame 210 represents one board installed on the floor corresponding to the floor frame 210. As in the example of FIG. 3, when two distribution boards 720 are arranged on each floor, two board blocks 211 are displayed inside one floor frame 210. Note that when the product use information screen 200 is displayed for the first time after new case information is registered, that is, when a board has not yet been registered on each floor, the board block 211 is not displayed inside the floor frame 21. Instead of this mode, a predetermined number of board blocks 211 may be displayed inside the floor frame 210 as default initial information.

[0042] An add button 212 is displayed at the top of each floor frame 210. When adding a board block 211, the user clicks this add button 212. When the user clicks the add button 212, an equipment edit screen 300 as shown in Fig. 5 is displayed on the screen of the terminal 20. Fig. 5 shows an example of the equipment edit screen 300 that is displayed when the add button 212 of the floor frame 210 corresponding to the 10th floor is pressed.

[0043] As shown in FIG. 5, a device edit screen 300 displays a list display section 310, an add row button 320, a delete row button 330, a register button 301, and a cancel button 302.

[0044] The list display section 310 displays a list of each panel installed on the floor. Each row of the list display section 310 lists information about one panel, specifically, information such as "equipment type", "installation location", and "panel name". The user can edit this information by operating the mouse, keyboard, etc. "Equipment type" refers to the type of distribution panel, and can select and input one of "distribution panel", "control panel", and "facility panel". "Installation location" refers to information indicating the floor number on which the panel is installed. The example in FIG. 5 is an example in which the add button 212 of the floor frame 210 corresponding to the 10th floor is pressed as described above, so "installation location" in all rows is displayed as "10F". "Panel name" refers to a symbol arbitrarily set to identify the panel, and is a character string such as "LP-10-01" displayed inside the panel block 211 as shown in FIG. 4.

[0045] When a new row is to be added, that is, when a new panel to be installed on the floor is to be added, the user clicks the Add Row button 320 and inputs the necessary information for the added row. When an existing row is to be deleted, the user checks the check box on the right side of the relevant industry and clicks the Delete Row button 330 below it.

[0046] By entering the necessary information into the equipment edit screen 300 as described above, the user can proceed with the design of the electrical equipment while placing panels on each floor.

[0047] When the editing work is completed, the user clicks the registration button 301. When the user clicks the registration button 301, the equipment editing screen 300 is closed, and the product usage information screen 200 of FIG. 4 is displayed again. At this time, the arrangement of the board blocks 211 in each floor frame 210 matches the contents of the list display section 310 edited immediately before. The arrangement of the board blocks 211 in each floor frame 210 is also transmitted to the input unit 11 of the design support system 10 and stored in the memory unit 14. In other words, the arrangement of the boards in the case information stored in the memory unit 14 is updated to match that input by the user.

[0048] An add button 220 is displayed in the upper right portion of the product information screen 200. The add button 220 is a button that is clicked to add a board block 211, similar to the add button 212. When the user clicks the add button 220, an equipment editing screen 300 similar to that of FIG. 5 is displayed on the screen of the terminal 20. However, the list display section 310 of the equipment editing screen 300 displayed at this time does not list only the boards installed on a specific floor, but all the boards installed throughout the building 700. In other words, not only the boards with the "installation location" set to "10F" as in the example of FIG. 5, but also the boards with the "installation location" set to "1F", the boards with the "installation location" set to "2F", etc. are all displayed in a list.

[0049] In this way, according to the design support system 10, the information on the panels to be installed on each floor of the building 700 can be displayed for each floor of the building 700 and the user can edit it individually, or it can be displayed for all floors together on one screen and edited.

[0050] When a user clicks on one of the multiple board blocks 211 displayed on the product information screen 200 in Fig. 4, a board specification editing screen 400 as shown in Fig. 6 is displayed. The board specification editing screen 400 is a screen that displays various information including the electrical specifications of all the loads 730 connected to the board corresponding to the board block 211 and allows the user to edit the information. Fig. 6 shows an example of the board specification editing screen 400 that is displayed when the board block 211 displayed as "LP-10-01" on the 10th floor in Fig. 4 is clicked.

[0051] The panel specification editing screen 400 is composed of a panel specification display section 410 in the upper section, a main line information display section 420 in the middle section, and a load display section 430 in the lower section.

[0052] The board specification display section 410 is an area where information about the board corresponding to the board block 211 that was previously clicked is displayed. The board specification display section 410 displays an installation location display section 411 and a board name display section 412. The installation location display section 411 displays the floor number on which the board is installed. The board name display section 412 displays a character string such as "LP-10-01" that is set as the name of the board.

[0053] In addition to the above, the panel specification editing screen 400 displays many other input fields for inputting information about the panel, but individual explanations of these will be omitted. Similarly, for the trunk line information display section 420 and the load display section 430 described next, only some of the fields displayed in Fig. 6 will be explained, and explanations of the others will be omitted.

[0054] The trunk line information display section 420 is a section that displays information about the trunk line 740 that is connected to the panel from the high voltage power receiving equipment 710. The trunk line information display section 420 displays a breaking capacity display section 421 and a trunk line specification display section 422.

[0055] The breaking capacity display section 421 is a section that displays the breaking capacity of the main breaker 721 provided on the panel. The letters "AT" displayed on the left side of the breaking capacity display section 421 mean so-called "ampere trip." For example, when "125" is displayed on the breaking capacity display section 421, it means that the main breaker 721 of the panel is one that performs a breaking operation when a current of 125A flows. The breaking capacity displayed in the breaking capacity display unit 421 is automatically input by the design support system 10 based on the electrical specifications (specifically, power consumption) of the load 730 displayed in the load display unit 430 described below. The larger the total value of the power consumption of the load 730, the larger the value displayed in the breaking capacity display unit 421. However, the user can manually rewrite the automatically input "AT" value as necessary.

[0056] The trunk line specification display section 422 is a section where a numerical value indicating the thickness of the trunk line 740 connected to the panel is displayed. The numerical value displayed in the trunk line specification display section 422 is automatically input by the design support system 10 based on the electrical specifications (specifically, power consumption) of the loads 730 displayed in the load display section 430 described below. The larger the total value of the power consumption of the loads 730, the larger the numerical value displayed in the trunk line specification display section 422. However, the user can manually rewrite the automatically input numerical value as necessary.

[0057] The load display section 430 is a section that displays the electrical specifications of the loads 730 that are connected to the panel and receive power supply. The load display section 430 displays a list of each of the loads 730 that are connected to the panel. Each line of the load display section 430 lists information about one load 730, specifically, information such as "load name," "power consumption," "breaker type," and "AT."

[0058] The user can edit this information by operating the mouse or keyboard. The "load name" is a character string that is arbitrarily set to identify the load 730. The "power consumption" is a section that displays the power consumption of the load 730 in a numerical value in units of "W" or "VA". The "breaker type" is the type of the branch breaker 722 installed between the load 730 and the panel, and can be selected and input from "MCCB", "ELB", or "TB". In addition, "TB" in the above means a terminal block. When the panel and the load 730 are directly connected without the branch breaker 722, "TB" is selected as the "breaker type". "AT" is the so-called "ampere trip" and is the breaking capacity of the branch breaker 722.

[0059] Of these pieces of information displayed in the load display section 430, at least the "load name" and "power consumption" are manually input by the user. An appropriate value is automatically input by the design support system 10 for "AT" in the load display section 430 according to the input numerical value of "power consumption." The larger the numerical value of power consumption, the larger the value displayed in the "AT" column. However, the user can manually rewrite the automatically input "AT" value as necessary.

[0060] When a user wishes to add a new row to the load display section 430, that is, when a user wishes to add a new load 730 to be connected to the panel, the user can click the add load button 401. When a user wishes to delete an existing row, the user can check the check box on the right edge of the row and click the delete load button 402 below it. The user can rewrite the information on the load 730 connected to the panel by appropriately editing the load display section 430.

[0061] By inputting the necessary information into the load display unit 430 as described above, the user can proceed with the design of the electrical equipment while placing the loads 730 connected to the panel on each floor.

[0062] When the editing work is completed, the user clicks the save button 403. As a result, the input information of the load 730 is transmitted to the input unit 11 of the design support system 10 and stored in the storage unit 14. In other words, the arrangement of the load 730 in the case information stored in the storage unit 14 is updated to match that input by the user.

[0063] Incidentally, even before the save button 403 is clicked, when each piece of information in the load display section 430 is updated by the user, the information is transmitted to the input section 11 of the design support system 10. The design support system 10 updates the value displayed in "AT" in the load display section 430 and the values ​​displayed in the interrupting capacity display section 421 and the trunk line specification display section 422 of the trunk line information display section 420 each time based on the updated information. For example, when the "power consumption" of some of the loads 730 is changed to a larger value than before, the value of "AT" for the load 730 is changed to a larger value, and the values ​​displayed in the interrupting capacity display section 421 and the trunk line specification display section 422 are also changed to larger values.

[0064] To enable such automatic change of the numerical values, the storage unit 14 prestores a correspondence relationship between the power consumption of the load 730 and the breaking capacity of the branch breaker 722, a correspondence relationship between the total value of the power consumption of the loads 730 connected to the panel and the breaking capacity of the main breaker 721, and a correspondence relationship between the total value of the power consumption of the loads 730 connected to the panel and the size of the trunk line 740. The design support system 10 automatically changes each numerical value as described above by referring to these correspondence relationships.

[0065] When the user clicks the save button 403 and the information on the load 730 stored in the memory unit 14 is updated, the determination unit 13 of the design support system 10 determines the specifications of the high-voltage power receiving equipment 710 to be installed in the building 700 based on the information. Specifically, the determination unit 13 of the design support system 10 determines the capacity of the transformer 711 that the high-voltage power receiving equipment 710 should have so as not to interfere with the power supply to each load 730 in the building 700. The determination unit 13 also calculates the external shape of the high-voltage power receiving equipment 710 required to accommodate components such as the transformer 711 and a capacitor, and also calculates the weight of the high-voltage power receiving equipment 710.

[0066] To enable the above-mentioned determination, the storage unit 14 prestores a correspondence relationship between the total value of the power consumption of all the loads 730 in the building 700 and the specifications of the high-voltage power receiving equipment 710. The determination unit determines the specifications of the high-voltage power receiving equipment 710 by referring to the correspondence relationship.

[0067] The above-mentioned specifications of the high-voltage power receiving equipment 710 determined by the determination unit 13 are stored in the storage unit 14. The user of the design support system 10 can display the specifications of the high-voltage power receiving equipment 710 on the screen of the terminal 20 by performing a necessary calling operation.

[0068] Furthermore, if the board specification editing screen 400 is closed without clicking the Save button 403, the various information previously entered by the user will be returned to the state it was in before the board specification editing screen 400 was displayed.

[0069] As described above, in the design support system 10 according to this embodiment, the determination unit 13 can automatically determine the specifications of the high-voltage power receiving equipment 710 based on the load information input by the user. In this embodiment, the load information input by the user to determine the specifications of the high-voltage power receiving equipment 710 is the electrical specifications of the load 730, specifically, the power consumption value input on the panel specification editing screen 400 in FIG.

[0070] As described with reference to FIG. 4, the user can place board blocks 211 inside each of the floor frames 210 displayed corresponding to each floor of the building 700. Each board block 211 is an icon indicating a board such as a distribution board 720 installed on each floor. Furthermore, when the board block 211 is clicked, information regarding the load 730 connected to the board, that is, the load information, is displayed as shown in FIG. 6. In other words, the board block 211 can be said to be an icon that contains and represents the load information.

[0071] On the product usage information screen 200 of FIG. 4, instead of displaying each board block 211 inside each floor frame 210, a list of the electrical specifications of each load 730 may be displayed inside each floor frame 210.

[0072] The user can input load information for each floor by clicking on panel blocks 211, which are displayed for each floor of the building 700, and operating the panel specification editing screen 400 that is displayed. The input load information is input to the input unit 11 of the design support system 10, as described above. In this way, the input unit 11 is configured as a part where the load information, which is information on the loads installed in the building 700, is input for each floor of the building 700.

[0073] 4, a board block 211, which is an icon representing load information, is displayed inside each floor frame 210. Such a product usage information screen 200 can be said to be a screen that displays load information separately for each floor of the building 700.

[0074] 6, a list of power consumption, which is an electrical specification of the load 730 installed on a specific floor, is displayed on one screen. Such a panel specification editing screen 400 can also be said to be a screen that displays load information separately for each floor of the building 700.

[0075] As described above, in the design support system 10, the load information is displayed on the screen for each floor of the building 700. This enables the user to intuitively perform work such as adding a panel or load 730 to a specific floor while specifically imagining what kind of load 730 will be installed on which floor of the building 700. The process of displaying the load information on the screen for each floor of the building 700 is realized by the display unit 12 of the design support system. The display unit 12 can be said to be a part that performs the process of displaying the load information for each floor of the building 700.

[0076] The "electrical specifications" of the load 730 input by the user as load information may be the power consumption value as in this embodiment, but may also be the voltage and current values.

[0077] As described above, in this embodiment, each numerical value of the power consumption in each row of the load display section 430 of the panel specification editing screen 400 is input to the input unit 11 as load information. Instead of this mode, the load information may be input to the input unit 11 as information indicating the interruption capacity of the main breaker 721 of each panel installed on each floor of the building 700. This is because the value of the interruption capacity of the main breaker 721 is determined so as not to interfere with the power supply to the load 730, and can be used as load information for determining the specifications of the high-voltage power receiving equipment 710. In this case, in the panel specification editing screen 400 of FIG. 6, only the interruption capacity displayed in the interruption capacity display section 421 may be directly input by the user as load information. In addition, in this case, the load display section 430 may not be displayed in the panel specification editing screen 400.

[0078] When the load information is input to the input unit 11 as information indicating the breaking capacity of the main breaker 721 as described above, the determination unit 13 may sum up the values ​​of the breaking capacities of the main breakers 721, i.e., the values ​​of the breaking capacities displayed on the breaking capacity display unit 421, for all panels, and determine the specifications of the high voltage power receiving equipment 710 based on the obtained sum. Also, the memory unit 14 may store in advance the correspondence relationship between the sum of the breaking capacities of all the main breakers 721 and the specifications of the high voltage power receiving equipment 710.

[0079] Even in the above configuration, the load information is input to the input unit 11 for each floor of the building 700. In this case, on the product usage information screen 200 in Fig. 4, instead of displaying each panel block 211 inside each floor frame 210, the breaking capacity of each main breaker 721 may be displayed in a list inside each floor frame 210.

[0080] Further, instead of the above embodiment, the load information may be input to the input unit 11 as information indicating the breaking capacity of the branch breaker 722 of each panel installed on each floor of the building 700. This is because the value of the breaking capacity of the branch breaker 722 is also determined so as not to interfere with the power supply to the load 730, and can be used as load information for determining the specifications of the high-voltage power receiving equipment 710. In this case, in the panel specification editing screen 400 of Fig. 6, only the numerical value in the AT column displayed in the load display unit 430 may be directly input by the user as the load information.

[0081] When the load information is input to the input unit 11 as information indicating the breaking capacity of the branch breaker 722 as described above, the determination unit 13 may sum up the values ​​of the breaking capacities of the branch breakers 722 for all the branch breakers 722 installed in the building 700, and determine the specifications of the high-voltage power receiving equipment 710 based on the obtained sum. Also, the storage unit 14 may store in advance a correspondence relationship between the sum of the breaking capacities of all the branch breakers 722 and the specifications of the high-voltage power receiving equipment 710.

[0082] Even in the above configuration, the load information is input to the input unit 11 for each floor of the building 700. In this case, on the product usage information screen 200 in Fig. 4, instead of displaying each panel block 211 inside each floor frame 210, the breaking capacity of each branch breaker 722 may be displayed in a list inside each floor frame 210.

[0083] In this embodiment, on the panel specification editing screen 400 of Figure 6, instead of the user manually inputting information into each line of the load display section 430, it is also possible to automatically input initial values ​​for each piece of information.

[0084] As shown in Fig. 6, an automatic input button 404 is displayed at the bottom of the panel specification editing screen 400. When the user clicks the automatic input button 404, a floor area input screen 500 shown in Fig. 7 is displayed. On the floor area input screen 500, an installation location display section 510, an area input section 520, an input button 501, and a cancel button 502 are displayed.

[0085] The installation location display section 510 is a section that displays the floor number on which each load 730 shown in Fig. 6 is installed. The value of the floor number displayed here is the same as the value of the floor number displayed in the installation location display section 411 in Fig. 6.

[0086] The area input section 520 is where the user inputs the floor area of ​​the floor corresponding to the display in the installation location display section 411. After the user inputs the floor area value in the area input section 520, the user clicks the input button 501. If the user wishes to discontinue inputting the value and return to the board specification editing screen 400 in FIG. 6, the user clicks the cancel button 502.

[0087] When the input button 501 is clicked, the floor area value input in the area input section 520 is sent to the input section 11 of the design support system 10. The design support system 10 again displays the panel specification editing screen 400 of Fig. 6, and inputs information indicating the specifications of the load 730 as initial values ​​in each row of the load display section 430 based on the input floor area. The information includes at least the load name and power consumption of the load 730.

[0088] The storage unit 14 of the design support system 10 stores in advance a correspondence relationship between the floor area value and a list of loads 730 that are likely to be installed on the floor. The design support system 10 refers to the correspondence relationship to automatically input the loads 730 as described above. The subsequent processing is the same as that described above.

[0089] The floor area values ​​input on the floor area input screen 500 are used as information for inputting the initial values ​​(which may also be called estimated values) of the loads 730 installed on the floors, and can therefore be called information on the loads 730 installed in the building 700, that is, "load information." In this way, the load information can also be input to the input unit 11 as information indicating the area of ​​each floor of the building 700.

[0090] Even in this case, the load information is input to the input unit 11 for each floor of the building 700. In this way, when the load information is input from the floor area input screen 500, a numerical value indicating the area of ​​the floor may be written inside each floor frame 210 on the product usage information screen 200 in Fig. 4.

[0091] The flowchart shown in Fig. 8 shows an outline of the process executed in the design support system 10 to realize the above-described functions. The series of processes shown in Fig. 8 is started when the user clicks the load information input button 122 on the case information screen 100 in Fig. 3.

[0092] In the first step S01 of this process, a process is performed in which the product usage information screen 200 in Fig. 4 is displayed on the screen of the terminal 20. After that, the user performs a process of adding a panel to each floor, a process of adding a load connected to the panel, etc. As a result, various types of load information are input to the input unit 11.

[0093] In this embodiment, the screen designs of the user interfaces such as the product usage information screen 200, the equipment editing screen 300, and the panel specification editing screen 400 are devised so that the user can input load information to the input unit 11 for each floor of the building 700. Furthermore, in this embodiment, the design of each of the above screens is further devised so that the load information that has been set up until now is displayed to the user separately for each floor of the building 700.

[0094] As described above, the load information input by the user for each floor may be the electrical specifications of each load 730, such as power consumption, the interrupting capacity of the main breaker 721 installed on each floor, the interrupting capacity of the branch breaker 722 installed on each floor, or the floor area of ​​each floor. In any case, the input load information is displayed on the screen of the terminal 20 by the display unit 12, divided for each floor of the building 700.

[0095] In step S02 following step S01, it is determined whether or not the user has performed an operation to input load information. If the registration button 301 is clicked on the device editing screen 300 in Fig. 5 to add a panel, or if the save button 403 is clicked on the panel specification editing screen 400 in Fig. 6 to add a load, the process proceeds to step S03. In other words, if an operation to update the load information is performed, the process proceeds to step S03. In other cases, the series of processes shown in Fig. 8 is terminated.

[0096] In step S03, a process is performed to update the load information stored in the storage unit 14 based on the load information input by the user. In step S04 following step S03, a process is performed by the determination unit 13 to determine the specifications of the high-voltage power receiving equipment 710 based on the load information updated as described above.

[0097] As described above, the user of the design support system 10 can display the specifications of the high-voltage power receiving facility 710 determined as described above on the screen of the terminal 20 by performing the necessary calling operation.

[0098] The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Any design modifications made by a person skilled in the art to these specific examples are also included within the scope of the present disclosure as long as they have the features of the present disclosure.
