[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] FIG. 1 is a diagram showing an embodiment of an information processing system of the present invention. As shown in FIG. 1, the information processing system in this embodiment has a database 100 and an information processing device 200. The database 100 and the information processing device 200 may be directly connected to each other, or may be connected via a commonly used communication network. The database 100 and the information processing device 200 are connected wirelessly or by wire. The database 100 is an externally accessible storage device that stores various information. The database 100 may be one in which a specific person is given access to the database 100 using a determined ID, password, or the like, or the database 100 may be one in which anyone can access the database 100. The information processing device 200 calculates and outputs various values ​​based on the data stored in the database 100 and data input to the information processing device 200 from the outside.

[0014] Fig. 2 is a diagram showing an example of data stored in the database 100 shown in Fig. 1. As shown in Fig. 2, the database 100 shown in Fig. 1 stores BIM data 110, intermediate process data 120, legal regulations data 130, special specification manual 140, catalog data 150, and labor-hour data 160. Hereinafter, these data stored in the database 100 will be referred to as reference information.

[0015] The BIM data 110 is BIM (Building Information Modeling) data including data of a skeleton model of a multi-story building. The skeleton model includes concrete and reinforcement information that constitutes the building. The skeleton model also includes information indicating the draw-in point, which is the starting point of the water supply, and information indicating the water supply point, which is the end point.

[0016] The intermediate formula data 120 includes numerical values, formulas, etc. calculated by the information processing device 200. The intermediate formula data 120 may also include calculation formulas, etc. that the information processing device 200 has used in past calculations.

[0017] The legal regulations data 130 is data on building laws and building regulations that must be observed when carrying out architectural design. The legal regulations data 130 is updated without delay every time the building laws and building regulations are revised. The legal regulations data 130 does not have to be stored in the database 100, and may be stored in an external specialized institution. Examples of the building laws and building regulations include the Building Standards Act, the Waterworks Act, and the Building Management Act.

[0018] The special specifications manual 140 may be data showing original specifications such as design drawing special specifications, main contractor specifications, etc. The special specifications manual 140 includes information input from outside to the information processing device 200 every time a water supply piping is designed. In addition, the special specifications manual 140 may include in advance a standard construction work specification that is commonly used.

[0019] The catalog data 150 is data that indicates specifications and prices of components that compose a building and components and tools that are necessary for installing water supply piping in a building, which are listed in a catalog or specification sheet. Examples of such components include pumps, water tanks, piping materials, and faucets. The catalog data 150 may be a list of data listed in the catalog for each component. The catalog data 150 may be organized by manufacturer and seller of the component.

[0020] The unit data 160 includes data that quantifies the effort required for each task. The unit data 160 may be a value calculated in advance based on statistical data of past tasks, or may be a value input (set) from outside.

[0021] It goes without saying that the data stored in the database 100 may not be stored in a single database 100, but may be stored in a plurality of databases that are separate from one another.

[0022] FIG. 3 is a diagram showing an example of the catalog data 150 shown in FIG. 2. The example shown in FIG. 3 is an example of a list of specifications described in a catalog of pumps included in the catalog data 150. The pump is installed outside or inside a building, and draws up water from a water pipe laid outside and supplies water to the inside of the building (especially the upper floors). As shown in FIG. 3, for each pump having a product name (model number), the nominal diameter (suction, discharge), model, output, phase and voltage, maximum water supply amount, total head, pressure tank filling pressure, noise value, price, and exclusive volume are stored. The items related to each pump included in the catalog data 150 are not limited to those shown in FIG. 3, and may include other items. In addition, the list shown in FIG. 3 can be rearranged by specifying a desired item among the items. In other words, if a priority item is specified from an external device such as the information processing device 200, the list shown in FIG. 3 can be rearranged in an order according to the priority order.

[0023] FIG. 4 is a diagram showing another example of the catalog data 150 shown in FIG. 2. The example shown in FIG. 4 is an example of a list of specifications described in a catalog of a water tank included in the catalog data 150. A water tank is a tank that is installed outside or inside a building and temporarily stores water from a water pipe laid outside. The water stored in the water tank is pumped up using a pump and supplied to the inside of the building (especially the upper floors). As shown in FIG. 4, for each water tank having a product name (model number), the material, model, exclusive capacity, hydrostatic pressure, earthquake resistance, snow load, and price are stored. The items related to each water tank included in the catalog data 150 are not limited to those shown in FIG. 4, and may include other items. In addition, the list shown in FIG. 4 can be rearranged by specifying a desired item among the items. In other words, if a priority item is specified from an external device such as the information processing device 200, the list shown in FIG. 4 can be rearranged in an order according to the priority order.

[0024] In addition, if the catalog data 150 includes a list of specifications listed in a catalog of piping materials, the material, model, price, etc. of each piping material are stored. In addition, if the catalog data 150 includes a list of specifications listed in a catalog of faucets, the required water supply pressure, price, etc. of each faucet are stored.

[0025] Fig. 5 is a diagram showing an example of the internal configuration of the information processing device 200 shown in Fig. 1. As shown in Fig. 5, the information processing device 200 shown in Fig. 1 has an input unit 210, a calculation unit 220, and an output unit 230. Note that Fig. 5 shows only main components related to this embodiment among the components included in the information processing device 200 shown in Fig. 1.

[0026] The input unit 210 inputs setting parameters from the outside. Specifically, the input unit 210 inputs information based on an operation received from the outside. The input unit 210 may be a keyboard, mouse, operation keys, etc. provided on a general PC (Personal Computer), or may be a touch panel that inputs information based on the contact or approach of an object such as a finger to a display that displays information.

[0027] The calculation unit 220 calculates the water supply piping of the building based on the setting parameters input by the input unit 210 and the reference information stored in the database 100. At this time, the water supply piping calculated by the calculation unit 220 includes information such as the water supply (receiving) method, the piping route, and the necessary cost. Specifically, when calculating the route of water supplied from the water pipe to the building, the calculation unit 220 calculates whether or not a pump is necessary to raise the water supplied from the water pipe to the upper floors of the building based on the setting parameters input by the input unit 210 and the reference information stored in the database 100. If the calculation unit 220 calculates that a pump is necessary, it calculates the necessary output of the pump. Then, the calculation unit 220 selects a pump according to the calculated output from the reference information stored in the database 100. Furthermore, the calculation unit 220 calculates whether or not a water receiving tank is necessary to store the water pumped up by the pump based on the setting parameters input by the input unit 210 and the reference information stored in the database 100. If the calculation unit 220 calculates that a water tank is necessary, it calculates the required capacity of the water tank. Then, the calculation unit 220 selects a water tank according to the calculated capacity from the reference information stored in the database 100.

[0028] The output unit 230 outputs piping information indicating the water supply piping calculated by the calculation unit 220. The output unit 230 may display the piping information on a display screen, or may transmit the piping information to another device or print it. A specific example of an output mode of the piping information in the output unit 230 will be described later. When the output unit 230 is a display having a touch panel function, the display has both the function of the input unit 210 and the function of the output unit 230.

[0029] The following describes an information processing method in the information processing system shown in Fig. 1. Figs. 6, 7, and 8 are flowcharts for explaining an example of the information processing method in the information processing system shown in Fig. 1.

[0030] First, the input unit 210 accepts an external operation and inputs predetermined parameters (step S1). At this time, the input unit 210 displays an input screen for the operator to input the predetermined parameters.

[0031] FIG. 9 is a diagram showing an example of an input screen displayed on the input unit 210 shown in FIG. 5. The input screen shown in FIG. 9 is displayed by performing a specific operation when the calculation unit 220 starts designing (calculating) this water supply piping. The input screen displayed is not limited to the one shown in FIG. 9, and may be any screen that allows necessary parameters to be input. The input screen may display, for example, input fields for inputting each parameter side by side. For example, as shown in FIG. 9, the input unit 210 shown in FIG. 5 displays, as an input screen, an input form including a reference button for selecting BIM and special specifications from the reference information stored in the database 100, whether or not to install a water tank for three cases, a pull-down menu for inputting priority items, and the like. Regarding the priority order, in the example shown in FIG. 9, the input screen allows the user to set priority items (price, snow load, noise level, hydrostatic pressure, exclusive area, earthquake resistance, etc.) for the pump and the water tank. For example, if a setting is made to give priority to price for a pump and a water tank, the calculation unit 220 selects a pump and a water tank to be installed with priority given to price from the catalog data 150. Also, a plurality of cases can be input.

[0032] When the input of the necessary parameters is completed, the calculation unit 220 judges whether the number of floors of the building exceeds three based on the input parameters and the BIM data 110 (step S2). If the building does not exceed three floors, the calculation unit 220 adopts a water supply direct pressure method as the piping method based on the input parameters and the reference information stored in the database 100, calculates the path of water supplied from the water supply to the building, and performs temporary piping (step S3). At this time, the calculation unit 220 refers to the BIM data 110, the legal regulations data 130, and the special specification manual 140 stored in the database 100. Next, the calculation unit 220 searches for the longest path on the highest floor among the paths that have been performed with temporary piping (step S4). The longest path on the highest floor is the path from the intake point, which is the starting point of the water supply to the building, to the water output position that is the farthest from the intake point, which is the top floor of the building. The calculation unit 220 outputs (writes) the found longest route to the highest floor to the BIM data 110 of the database 100 (step S5). At this time, if the parameters input in step S1 are parameters for multiple cases, the longest route to the highest floor for each of the multiple cases is written to the BIM data 110 of the database 100.

[0033] The calculation unit 220 performs a head calculation based on the input parameters and the BIM data 110 stored in the database 100 (step S6). The calculation unit 220 outputs (writes) the result of the head calculation to the intermediate formula data 120 of the database 100 (step S7). Next, the calculation unit 220 determines whether the pressure of the water output from the end of the longest route on the highest floor meets the required pressure (water pressure) based on the input parameters, the route searched in step S4, and the head calculated in step S6 (step S8). Here, the required pressure (water pressure) is a value according to the legal regulations data 130, and if it is included in the setting parameters input by the input unit 210 in step S1, it meets that value. If the output water pressure (water pressure) does not meet the required pressure (water pressure), the calculation unit 220 determines that a pump needs to be installed (step S9). On the other hand, if the building is more than three stories tall in step S2, the process of step S9 is performed.

[0034] If it is determined that the pump needs to be installed, the calculation unit 220 determines whether or not there is an obligation to install a water tank based on the legal regulations data 130 in the database 100 (step S10). If there is no obligation to install a water tank, the calculation unit 220 determines whether or not there is a request to install a water tank based on the parameters input in step S1 (step S11). If there is no request to install a water tank, the calculation unit 220 adopts a booster water supply method using a pump (without installing a water tank) as a piping method based on the input parameters and the reference information stored in the database 100, calculates a route for water to be supplied from the waterworks to the building, and performs temporary piping (step S12). At this time, the calculation unit 220 refers to the BIM data 110, legal regulations data 130, and special specification manual 140 stored in the database 100. Next, the calculation unit 220 searches for the longest route on the highest floor among the routes for which temporary piping has been performed (step S13). The calculation unit 220 outputs (writes) the found longest route to the highest floor to the BIM data 110 of the database 100 (step S14). At this time, if the parameters input in step S1 are parameters for multiple cases, the longest route to the highest floor for each of the multiple cases is written to the BIM data 110 of the database 100.

[0035] The calculation unit 220 performs a head calculation based on the input parameters and the BIM data 110 stored in the database 100 (step S15). The calculation unit 220 outputs (writes) the result of the head calculation to the intermediate formula data 120 of the database 100 (step S16). Next, the calculation unit 220 determines whether the pressure of the water output from the pump satisfies the required pressure (water pressure) based on the input parameters, the route searched in step S13, the head calculated in step S15, and the pump specifications in the catalog data 150 (step S17). Here, the required pressure (water pressure) is the pressure of water output by the pump required to output water of a preset pressure (water pressure) from the end of the longest route on the highest floor. If the pressure of the water output from the pump does not satisfy the required pressure (water pressure), the calculation unit 220 determines whether the output of the pump can be increased based on the input parameters and the reference information stored in the database 100 (step S18). At this time, the calculation unit 220 selects a pump with an even larger output value from the catalog data 150, and determines whether any of the selected pumps satisfies the conditions of the input parameters, the legal regulations data 130, and the special specification manual 140. If it is determined that the pump output can be increased, the calculation unit 220 increases the pump output by one (step S19) and performs the process of step S15. Increasing the pump output by one means increasing the output of the multiple pumps included in the catalog data 150 to the next larger value according to the specifications, or changing to a pump with the next larger output. On the other hand, if it is determined in step S18 that the pump output cannot be increased any further, the calculation unit 220 determines that a water tank needs to be installed (step S20).

[0036] If it is determined that the installation of a water tank is necessary, the calculation unit 220 adopts a water tank system using a water tank as a piping system based on the input parameters and the reference information stored in the database 100 (particularly, the specifications of the water tank in the catalog data 150), calculates the route of water supplied from the waterworks to the building, and performs temporary piping (step S21). At this time, the calculation unit 220 refers to the BIM data 110, the statute and regulation data 130, and the special specification manual 140 stored in the database 100. Next, the calculation unit 220 searches for the longest route on the highest floor among the routes on which temporary piping has been performed (step S22). The calculation unit 220 outputs (writes) the longest route on the highest floor that has been searched to the BIM data 110 of the database 100 (step S23). At this time, if the parameters input in step S1 are parameters for multiple cases, the longest route on the highest floor for each of the multiple cases is written to the BIM data 110 of the database 100.

[0037] The calculation unit 220 performs a head calculation based on the input parameters and the BIM data 110 stored in the database 100 (step S24). The calculation unit 220 outputs (writes) the result of the head calculation to the intermediate formula data 120 of the database 100 (step S25). Next, the calculation unit 220 determines whether or not the pressure of the water output from the pump (water pressure) satisfies the required pressure (water pressure) based on the input parameters, the route searched in step S22, the head calculated in step S24, and the pump specifications in the catalog data 150 (step S26). If the pressure of the water output from the pump (water pressure) does not satisfy the required pressure (water pressure), the calculation unit 220 increases the output of the pump by one (step S27) and performs the process of step S24.

[0038] On the other hand, if the pressure of the water output from the pump (water pressure) satisfies the required pressure (water pressure) in step S26, the calculation unit 220 calculates the price of a receiving tank piping pump of the receiving tank type using the pump and the receiving tank based on the catalog data 150 and the labor cost data 160 stored in the database 100 (step S28). At this time, if the setting parameters input by the input unit 210 in step S1 include the price of the pump as a condition, the calculation unit 220 selects a pump whose price satisfies the setting parameters input by the input unit 210 in step S1. In addition, the calculation unit 220 calculates the capacity of the receiving tank based on the catalog data 150 (step S29). At this time, if the setting parameters input by the input unit 210 in step S1 include the capacity of the receiving tank as a condition, the calculation unit 220 selects a receiving tank whose capacity satisfies the setting parameters input by the input unit 210 in step S1. The calculation unit 220 also calculates the volume of the piping pump based on the catalog data 150 (step S30). At this time, if the setting parameters input by the input unit 210 in step S1 include the volume of the pump as a condition, the calculation unit 220 selects a pump whose volume satisfies the setting parameters input by the input unit 210 in step S1. The calculation unit 220 also calculates other designated priority items input in step S1 (step S31). In this way, the required output of the pump is calculated by the piping, but the calculation unit 220 selects the price and other performance according to the setting parameters input by the input unit 210. Then, the output unit 230 outputs the result calculated by the calculation unit 220 as piping information indicating the water supply piping (step S32). For example, the output unit 230 displays the result calculated by the calculation unit 220 on a screen.

[0039] FIG. 10 is a diagram showing an example of a screen displayed by the output unit 230 shown in FIG. 5 in step S32. The output unit 230 that displays the screen shown in FIG. 10 is a display (display unit) equipped with a touch panel function that also serves as the input unit 210 shown in FIG. 5. As shown in FIG. 10, a plurality of results calculated by the calculation unit 220 are displayed. The results calculated by the calculation unit 220 that are displayed by the output unit 230 include a display button for selecting the display of BIM data, a display for inputting the necessity of a water tank, and exclusive volume, price, noise value, and other items. In addition, a button for selecting the display of the intermediate formula written in the intermediate formula data 120 in the above-mentioned process, a button for instructing the calculation unit 220 to perform recalculation, and a button for outputting the result (output button) are displayed. When the button for instructing to perform recalculation is selected, the process can be performed again from step S1, and the output unit 230 can output a different result by inputting different setting parameters by the input unit 210. The example shown in FIG. 10 is a case in which a water tank system using a water tank is adopted as the piping system.

[0040] Fig. 11 is a diagram showing an example of a screen displayed by the output unit 230 when the output button shown in Fig. 10 is selected. As shown in Fig. 11, in addition to the display shown in Fig. 10, the selected item is also displayed on the screen. As a result, a plurality of cases calculated by the calculation unit 220 are displayed.

[0041] 10 and 11 are also output (written) to the BIM data 110. In addition, by writing the output data to the BIM data 110, the written output data may be used as statistical data thereafter.

[0042] 1 may store a trained learning model in which machine learning is performed on the water supply piping calculated by the calculation unit 220 for the setting parameters input by the input unit 210. In this case, the calculation unit 220 inputs the setting parameters input by the input unit 210 to the learning model, thereby acquiring information on the water supply piping from the learning model. The learning model may be constructed by previously setting a learning phase, or may be obtained from a specialized company or the like.

[0043] In this way, in the present invention, the water supply piping of a building is calculated based on the setting parameters input from the outside and the reference information including the BIM data, building regulations, and the specifications and prices of materials required for the water supply piping, which are stored in advance in the database, and the piping information indicating the water supply piping is output. Therefore, flexible water supply piping according to each request can be easily performed without manual calculation.
