The storage unit is implemented by a RAM (Random Access Memory), a ROM (Read Only Memory), etc., for example.

[0067] (2) Detailed Structure

[0068] (2-1) Conversion Unit

[0069] The conversion unit 11 converts a paper design drawing into image data. The paper design drawing is a drawing representing a specified area within a building. The paper design drawing can be, for example, a top view, a floor plan, etc. The top view of a building is a top view of each floor showing the shape, floor area, etc. The floor plan is a detailed sectional view showing the joints, dimensions, etc. from the foundation to the eaves end when the building is cut.

[0070] The paper design drawing transformed into image data can be one sheet or multiple sheets. The elevation view, which is a paper design drawing, can also be further transformed into image data. The elevation view is a drawing showing the exterior of a building.

[0071] The conversion unit of this embodiment reads Figure 2 the required area of the paper design drawing shown as image data. The image data can be converted into PDF data.

[0072] (2-2) Extraction unit

[0073] The extraction unit 12 extracts information of at least one of lines and characters from the image data converted by the conversion unit 11. By extracting lines as information, the extraction unit 12 can delimit a specified area. The extraction unit 12 distinguishes line types according to the lines in the image data. The line types are line types such as dimension lines, lines for dividing rooms, etc. For example, in a paper design drawing, dimension lines are represented by single-dot dash lines, and walls are represented by solid lines.

[0074] The extraction unit 12 extracts characters as information. The characters include numerical values. The extraction unit 12 extracts the dimension information of the specified area from the characters in the image data as information. The dimension information is used for calculating the area of the specified area.

[0075] In addition, the extraction unit 12 extracts floor information for identifying floors from the characters in the image data of the top view as information. The floor information is information for identifying the floor of the specified area, such as information of the first floor, the second floor, etc.

[0076] In addition, the extraction unit 12 extracts window information related to windows from the lines in the image data as information. The window information is information related to the windows in the specified area, such as information on the presence or absence of windows.

[0077] Refer to Figure 2 for an example of the information extracted by the extraction unit 12. In Figure 2In the image data obtained after converting the paper drawing, the extraction unit 12 extracts characters such as "rental office" which is the room name of the area R1. In addition, the extraction unit 12 extracts the solid lines that make up the wall of the area R2. In addition, the extraction unit 12 extracts the straight lines and curves that make up the door of the area R3. In addition, the extraction unit 12 extracts the straight lines and curves that make up the window of the area R4. In addition, the extraction unit 12 extracts characters such as "8250" which is the dimension information of the area R5. In addition, the extraction unit 12 extracts characters such as "PS", "EPS", and "DS" that represent each space of the area R6.

[0078] In addition, the extraction unit 12 can utilize artificial intelligence (AI: artificial intelligence). In this case, a learned method capable of recognizing characters, numerical values, objects, line types, etc. is used. Examples of the learning method are supervised learning. Examples of the models or algorithms used in supervised learning include regression analysis, time series analysis, decision trees, support vector machines, neural networks, ensemble learning, etc.

[0079] (2-3) First storage unit

[0080] The first storage unit 13 stores first information and second information. The first information associates the room name with whether an air conditioner is required. The first information is, for example, Figure 3 as shown, a list that enumerates multiple room names and whether an air conditioner is required based on each room name.

[0081] The second information associates the room name with the heat load level. As Figure 4 shown, the second information is a list that gives multiple room names and the heat load level based on that room name. The level related to the high or low heat load represents a reference for relatively high or low heat load, and can be represented as high or low as Figure 4 shown, or can represent the evaluated numerical value.

[0082] (2-4) Judgment unit

[0083] The judgment unit 14 identifies at least one of the room name and the object based on the information extracted by the extraction unit 12, and judges whether the specified area in the building is an area that requires an air conditioner according to the identification result.

[0084] Specifically, the determination unit 14 identifies the room name based on the information of the characters extracted by the extraction unit 12, and determines whether the specified area in the building is an area that requires an air conditioner according to the identification result. In addition, the determination unit 14 identifies the object based on the information of the line extracted by the extraction unit 12, and determines whether the specified area in the building is an area that requires an air conditioner according to the identification result. In addition, the determination unit 14 identifies the room name based on the information of the line extracted by the extraction unit 12, and determines whether the specified area in the building is an area that requires an air conditioner according to the identification result. In addition, the determination unit 14 identifies the room name based on the information of the characters and the information of the line extracted by the extraction unit 12, and determines whether the specified area in the building is an area that requires an air conditioner according to the identification result.

[0085] Here, the object is an object for identifying a predetermined area. Specifically, the object is an object for identifying the boundary of the specified area and / or an object for calculating the heat load of the specified area. If specific examples are listed, the object is at least one of a door, a column, a beam, an elevator, an elevator hall, a chair, a table, a hot water supply device, an entrance, a window, a wall, and a toilet.

[0086] The determination unit 14 can identify the object and determine whether the specified area in the building is an area that requires an air conditioner according to the identified object. In addition, the determination unit 14 can obtain the room name as the identification result based on the object and determine whether the specified area in the building is an area that requires an air conditioner.

[0087] List an example of determining whether an air conditioner is required based on the identified object. If a hot water supply device is identified as the object, since the heat load of the hot water supply device is large, the determination unit 14 determines that it is an area that requires an air conditioner.

[0088] Give an example of obtaining the room name as the identification result based on the object. If a table and a chair are identified as the object, the identification result that the specified area is a living room such as a meeting room or an office is obtained. If a toilet bowl is identified as the object, the identification result that the specified area is a toilet is obtained. If a step is identified as the object, the identification result that the specified area is a staircase room is obtained. If an elevator is identified as the object, the identification result that the specified area is an elevator is obtained. If an elevator is identified as the object, the identification result that the specified area in front of the elevator is an elevator hall is obtained. If a water heater is identified as the object, the identification result that the specified area is a hot water supply room is obtained.

[0089] The determination unit 14 delimits the specified area by distinguishing the room division and the dimension line based on at least one of the line type and the dimension value. For example, in Figure 2In the image data obtained by converting the paper design drawing, considering that area R2 is the wall and area R3 is the door, a specified area is delimited. For the delimited area, the determination unit 14 determines whether an air conditioner is required.

[0090] When it is difficult to determine whether an air conditioner is required based on the room name as the recognition result, the determination unit 14 can use other recognition results. Specifically, window information related to windows is recognized as the object. In this case, the determination unit 14 recognizes the room name and window information of the specified area to determine whether it is an area where an air conditioner is required. When it is difficult to determine whether an air conditioner is required based on the room name, for example, if there is a window, it is determined that the area does not require an air conditioner, and if there is no window, it is determined that the area requires an air conditioner.

[0091] In addition, when it is difficult to determine whether an air conditioner is required based on the room name as the recognition result, the determination unit 14 can use the first information stored in the first storage unit 13. Specifically, the determination unit 14 reads out the first information from the first storage unit 13 and determines whether it is an area where an air conditioner is required based on the room name recognized based on the first information.

[0092] The determination unit 14 of the present embodiment associates the floor information with the room name and determines whether it is an area where an air conditioner is required. For example, in the extraction unit 12, when floor information such as "1st floor top view" and room name such as "meeting room" can be extracted as characters, the determination unit 14 determines whether the meeting room on the 1st floor is an area where an air conditioner is required. If the extraction unit 12 can extract the floor information, even for the same room name, it is possible to consider whether it is the 1st floor or a high floor and determine whether an air conditioner is required.

[0093] In the case of updating an object such as building renovation, information related to the air conditioner in the past (before the update) can be used. Specifically, the determination unit 14 recognizes the air conditioner as the object and determines whether the specified area in the building is an area where an air conditioner is required based on the recognition result. In the case of updating an object, if the determination unit 14 recognizes that there was an air conditioner in the same area in the past, it is determined that an air conditioner is also required after the update. In addition, if the determination unit 14 recognizes that there was no air conditioner in the same area in the past, it is determined that an air conditioner is not required after the update.

[0094] Here, an example of determining whether a specified area in a building is an area that requires an air conditioner when the determination unit 14 obtains a room name as an identification result is listed. When the identification result of the specified area is a living room such as a conference room or an office, the determination unit 14 determines that it is an area that requires an air conditioner based on the room name. When the identification result of the specified area is a lecture hall, an elevator (EV), a duct space (PS), an electret duct space (EPS), an electret space (ES), or a duct space (DS), the determination unit 14 determines that it is an area that does not require an air conditioner based on the room name. When the specified area is a toilet, an elevator hall, or a hot water supply room, the determination unit 14 determines whether an air conditioner is required only based on the room name. In this case, the determination unit 14 reads, for example, first information listing the room name and whether an air conditioner is required from the first storage unit 13, and determines whether an air conditioner is required based on the first information.

[0095] (2-5) Decision-making unit

[0096] The decision-making unit 21 determines the area determined by the determination unit 14 to be an area that requires an air conditioner as an area that requires an air conditioner.

[0097] The decision-making unit 21 obtains information related to the area from a paper design drawing in order to prompt the configuration of the air conditioner to be installed in the specified area in the prompt unit 23 described later. Information related to the area refers to the area of the area, the room name, etc. The extraction unit 12 and the determination unit 14 are used to obtain information related to the area.

[0098] In addition, the decision-making unit 21 obtains the main body information of the building. The main body information is obtained from the information extracted by the extraction unit 12. The main body information is, for example, the thickness of walls, glass, etc., and the presence or absence of windows. The main body information is obtained from the information extracted by the extraction unit 12.

[0099] The decision-making unit 21 further obtains information related to the specified area from at least one of the elevation view of the building and the floor plan of the building. In the present embodiment, the conversion unit 11 converts at least one of the elevation view and the floor plan into image data, and the extraction unit 12 extracts information of at least one of lines and characters from the image data, whereby the decision-making unit 21 further obtains information on the specified area.

[0100] In addition, the decision-making unit 21 obtains information related to the specified area from a paper design drawing, but it is not limited thereto.

[0110] The list can also have information related to the installation distance of the air conditioner. This information relates to the prohibited installation distance determined according to the presented air conditioner. Additionally, the air conditioner in this embodiment is an indoor unit.

[0111] (2-9) Presentation unit

[0112] The prompting unit 23 prompts the arrangement of the air conditioner provided for the area based on the information related to the area determined to require the air conditioner. The prompting unit 23 prompts at which position in the specified area the determined air conditioner, such as the type, horsepower, and number of units, is to be arranged in the area.

[0113] In the present embodiment, the prompting unit 23 prompts the arrangement of the air conditioner provided for the area based on the information related to the area obtained from the top view. In addition, the information related to the area obtained from the top view includes the information from the extraction unit 12, the determination unit 14, the arithmetic unit 15, and the calculation unit 16.

[0114] Specifically, the prompting unit 23 prompts the arrangement of the air conditioner based on the heat load calculated according to the room name. In detail, considering the room name read from the top view, the prompting unit 23 prompts the arrangement of the air conditioner based on the heat load calculated by the arithmetic unit 15.

[0115] In addition, the prompting unit 23 prompts the arrangement of the air conditioner based on the heat load calculated according to the main body information and the information related to the area. The prompting unit 23 selects the necessary information as the information related to the area.

[0116] In addition, the prompting unit 23 prompts the arrangement of the air conditioner based on the information related to the area obtained from at least one of the elevation view and the floor plan of the building. Specifically, on the basis of the top view, the prompting unit 23 prompts the arrangement of the air conditioner based on the information related to the area obtained from at least one of the elevation view and the floor plan.

[0117] In addition, the prompting unit 23 associates the name of the top view with the room name and prompts the arrangement of the air conditioner provided for the area. Specifically, the floor of the area is determined according to the name of the top view, and the prompting unit 23 prompts the arrangement of the air conditioner based on the heat load calculated considering the room name on that floor.

[0118] The prompting unit 23 also prompts the arrangement of the air conditioner based on the required capacity calculated by the calculation unit 16. Specifically, according to the required capacity, the type, horsepower, number of units, etc. of the air conditioner are selected.

[0119] The prompting unit 23 calculates the number of air conditioners to be prompted based on the structure related to past air conditioners, and prompts the configuration of the air conditioners based on the calculated number. The prompting unit 23 reads out the list of structures related to past air conditioners from the second storage unit 22, and learns about the types, horsepower, number, etc. of the air conditioners installed in this area. Therefore, it can calculate the required capacity of the installed air conditioners based on this information. If it reads out the structure related to the prompted air conditioners from the second storage unit 22 and selects, for example, the type from the list of newly prompted air conditioners, it can calculate the horsepower and number of the required air conditioners. In this case, even without calculating the heat load of the specified area, it can prompt the number of new air conditioners, etc. In addition, the prompting unit 23 can also prompt air conditioners of the same type based on the information related to the types of the air conditioners installed in this area, without selecting the types of the newly installed air conditioners.

[0120] The prompting unit 23 prompts the configuration of the air conditioners based on the installation distance of the air conditioners. Specifically, it reads out the list with information related to the installation distance of the air conditioners from the second storage unit 22. It determines the distance between multiple air conditioners based on the list. When it can identify columns, beams, etc. as objects, the prompting unit 23 also considers these identification results to prompt the configuration of multiple air conditioners.

[0121] Here, referring to Figures 7 - 9 , an example of the configuration of the air conditioners prompted by the prompting unit 23 is given. In Figures 7 - 9 , the indoor unit is shown as the air conditioner. In the case of a square shown in Figure 7 and a rectangular living room shown in Figure 8 in a top view, the prompting unit 23 prompts the configuration in which the ceiling-embedded indoor units 100 with four blowing directions are arranged at equal distances from each other. When the specified area in a top view is a rectangular living room shown in Figure 9 and the lighting 101 is identified as an object, the prompting unit 23 prompts the configuration in which multiple indoor units 100 with two blowing directions and matching the shape of the lighting 101 are arranged side by side with the lighting 101. In this way, the prompting unit 23 prompts the configuration of multiple indoor units 100 based on the shape of the specified area and / or the layout of the columns, beams, and / or lighting 101 installed in the specified area.

[0122] In addition, the prompting unit 23 can utilize artificial intelligence (AI: artificial intelligence). In this case, a learned method capable of recognizing characters, numerical values, objects, line types, etc. is used. The learning method is, for example, supervised learning. As the models or algorithms used in supervised learning, regression analysis, time series analysis, decision trees, support vector machines, neural networks, ensemble learning, etc. can be cited.

[0123] (3) Set up an auxiliary method (including a method for determining necessity and a method for configuring prompts)

[0124] Refer to Figures 1 - 10 , and describe the setting auxiliary method of the air conditioner in an embodiment. The setting auxiliary method includes a method for determining necessity and a method for configuring prompts. The method for determining necessity and the method for configuring prompts of the air conditioner in this embodiment are performed using the necessity determination system 10 and the configuration prompt system 20 of the above air conditioner.

[0125] (3-1) Input of paper design drawings

[0126] First, as Figure 10 shown, input the paper design drawing of the building (step S10). The paper design drawing is not particularly limited and can be a top view, etc.

[0127] (3-2) Conversion to image data

[0128] Next, the paper design drawing is converted into image data by the conversion unit 11 (step S20).

[0129] (3-3) Extraction of information of at least one of lines and characters

[0130] Next, the extraction unit 12 extracts information of at least one of lines and characters from the image data (step S30).

[0131] (3-4) Judgment of the area where the air conditioner is needed

[0132] Next, the judgment unit 14 identifies at least one of the room name and the object from the information, and judges whether the specified area in the building is an area where the air conditioner is needed according to the identification result (step S40).

[0133] Specifically, according to the information extracted by the extraction unit 12, it is judged whether at least one of the room name and the object can be identified (step S41). In this process (S41), when at least one of the room name and the object cannot be identified, it is considered that it is impossible to automatically judge whether the air conditioner is needed, and manual input is used to judge whether the air conditioner is needed.

[0134] On the other hand, in the process (S41), when at least one of the room name and the object can be identified, it is judged whether the specified area in the building is an area where the air conditioner is needed according to the identification result (step S42). In this process (S42), as described above, the first information can be read out from the first storage unit 13, and the judgment unit 14 judges whether it is an area where the air conditioner is needed according to the room name identified based on the first information.

[0135] In process (S42), when it is impossible to determine whether an air conditioner is needed, it is considered that it is not possible to automatically determine whether an air conditioner is needed, and whether an air conditioner is needed is determined by manual input.

[0136] In process (S42), when it is possible to determine whether an air conditioner is needed, it is determined whether an air conditioner is needed (step S43). In this process (S43), if it is determined that the specified area is not an area where an air conditioner is needed, the determination is output, and the auxiliary system 1 is set and ended. On the other hand, if it is determined that the specified area is an area where an air conditioner is needed, the determination unit 21 determines that the specified area is an area where an air conditioner is needed (step S50).

[0137] (3-5) Prompt for the configuration of the air conditioner

[0138] Next, the configuration of the air conditioner to be installed in the area determined to be an area where an air conditioner is needed is prompted by the prompting unit 23 (step S60). In this process (S60), based on the information related to the area obtained from the top view, the configuration of the air conditioner is prompted.

[0139] In step S60, as Figure 11 shown, it is determined whether there is a list of the structures related to the past air conditioners in the specified area (step S61). In addition, in process (S61), the case where there is a list of the structures related to the past air conditioners in the Figure 5 shown specified area is a case of updating the object and is a case where the drawing of the past specified area can be obtained. On the other hand, the case where there is no list of the structures related to the past air conditioners in the specified area is a case of updating the object, but it is a case where the drawing of the past specified area cannot be obtained and a case of a new object.

[0140] (3-5-1) Case where there is a list of the structures related to the past air conditioners

[0141] The second storage unit 22 stores a list related to the following structures: the structures related to the past air conditioners in the specified area and the structures related to the prompted air conditioners. The prompting unit 23 reads out this list, calculates the number of the prompted air conditioners based on the structures related to the past air conditioners, and prompts the configuration of the air conditioner based on the calculated number. Specifically, according to the Figure 6 shown list of the structures related to the past air conditioners, the type, horsepower, number, etc. of the air conditioners installed in this area are known, so the required capacity of the air conditioner is calculated (step S62). Next, from Figure 5Select, for example, the type from the list of the new prompt air conditioners shown (step S63). Based on the calculated required capacity and type, calculate the required horsepower and number of air conditioners (step S64). Therefore, the configuration of the air conditioner can be prompted by the prompt unit 23 (step S65). In this way, if there is a list of structures related to past air conditioners, the calculation of the heat load in a specified area can be omitted.

[0142] (3-5-2) Case where there is no list of structures related to past air conditioners

[0143] On the other hand, in the case where there is no list of structures related to past air conditioners, as Figure 11 shown, the heat load of the specified area is calculated by the calculation unit 15 (step S66). Then, based on the calculated heat load, the required capacity of the air conditioner is calculated by the calculation unit 16 (step S67). Thereby, the configuration of the air conditioner can be prompted by the prompt unit 23 (step S65).

[0144] (4) Features

[0145] (4-1) Yes / No judgment system for air conditioners

[0146] In the yes / no judgment system 10 that constitutes the setting assistance system 1 of the air conditioner of the present embodiment, by converting the paper design drawing into image data, information for judging whether a specified area in the building is an area that requires an air conditioner can be extracted from the image data.

[0147] In particular, when updating an object, sometimes CAD data cannot be obtained and only a paper design drawing exists. Even in the case of an updated object with only a paper design drawing, according to the yes / no judgment system 10 that constitutes the setting assistance system 1 of the present embodiment, manual work can be reduced and it can be efficiently judged whether it is an area that requires an air conditioner.

[0148] (4-2) Air conditioner configuration prompt system

[0149] In the configuration prompt system 20 that constitutes the setting assistance system 1 of the air conditioner of the present embodiment, information related to the area that requires an air conditioner is obtained from the paper design drawing of the building. Based on this information, the air conditioner to be installed in the specified area can be configured. Therefore, the efficiency of the design work of the air conditioner installed in the area can be improved. Therefore, it is possible to efficiently prompt the air conditioner to be installed in the specified area in the building based on the paper design drawing of the building.

[0150] (4-3) Setting up an auxiliary system

[0151] In the setting up auxiliary system 1 of the present embodiment, the need or no - need judgment system 10 is used to judge whether it is an area that requires an air conditioner. For the area that requires an air conditioner judged by the need or no - need judgment system 10, the configuration prompting system 20 is configured to prompt the configuration of the air conditioner. Therefore, the setting up auxiliary system 1 can efficiently prompt the layout to be equipped in the area that requires an air conditioner according to the paper design drawing of the building.

[0152] (5) Variation

[0153] The setting up auxiliary system 1 of the above - mentioned embodiment is a system that uses the need or no - need judgment system 10 and the configuration prompting system 20 together, but it is not limited to this. The setting up auxiliary system 1 can also be used as a system that separates the need or no - need judgment system 10 from the configuration prompting system 20.

[0154] In addition, it has been described that the extraction unit 12 and the prompting unit 23 can use AI, but any structure such as the judgment unit 14 included in the setting up auxiliary system 1 can also use AI. When multiple structures in the setting up auxiliary system 1 use AI, the multiple AIs can cooperate with each other.
