　（２－２）抽出部
　抽出部１２は、変換部１１で変換した画像データから、線及び文字の少なくとも一方の情報を抽出する。抽出部１２は、情報として線を抽出することにより、所定エリアを画定できる。抽出部１２は、画像データの線から、線種を区別する。線種とは、寸法線、部屋等を区切る線などの線の種類である。例えば、紙図面において、寸法線は一点鎖線で示され、壁は実線で示されている。 (2-2) Extraction unit The extraction unit 12 extracts at least one information of a line and a character from the image data converted by the conversion unit 11. The extraction unit 12 can define a predetermined area by extracting a line as information. The extraction unit 12 distinguishes the line type from the line of the image data. The line type is a type of line such as a dimension line and a line that separates rooms and the like. For example, in a paper drawing, the alternate long and short dash line is shown and the wall is shown as a solid line.
　抽出部１２は、情報として文字を抽出する。文字は数値を含む。抽出部１２は、画像データの文字から、所定エリアの寸法情報を、情報として抽出する。寸法情報は、所定エリアの面積を演算するためのものである。 The extraction unit 12 extracts characters as information. Characters include numbers. The extraction unit 12 extracts dimensional information of a predetermined area as information from the characters of the image data. The dimensional information is for calculating the area of a predetermined area.
　また抽出部１２は、平面図の画像データの文字から、情報として、フロアを識別するフロア情報を抽出する。フロア情報とは、所定エリアのフロアを識別する情報であって、例えば１階、２階などの情報である。 Further, the extraction unit 12 extracts floor information for identifying the floor as information from the characters of the image data in the plan view. The floor information is information that identifies a floor in a predetermined area, such as the first floor and the second floor.
　また抽出部１２は、画像データの線から、情報として、窓に関する窓情報を抽出する。窓情報とは、所定エリアの窓に関する情報であって、例えば窓の有無などの情報である。 Further, the extraction unit 12 extracts window information regarding the window as information from the line of the image data. The window information is information about windows in a predetermined area, such as the presence or absence of windows.
　抽出部１２が抽出する情報を、図２を参照して例を挙げる。図２の紙図面を変換した画像データにおいて、抽出部１２は、領域Ｒ１の部屋名である貸事務所という文字を抽出する。また、抽出部１２は、領域Ｒ２の壁を構成する実線を抽出する。また、抽出部１２は、領域Ｒ３のドアを構成する直線及び曲線を抽出する。また、抽出部１２は、領域Ｒ４の窓を構成する直線及び曲線を抽出する。また、抽出部１２は、領域Ｒ５の寸法情報である８２５０という文字を抽出する。また、抽出部１２は、領域Ｒ６の各スペースを示すＰＳ、ＥＰＳ、及びＤＳという文字を抽出する。 An example of the information extracted by the extraction unit 12 will be given with reference to FIG.

In this case, a trained one that can identify characters, numerical values, objects, line types, etc. is used. The learning method is, for example, supervised learning. Models or algorithms used in supervised learning include regression analysis, time series analysis, decision trees, support vector machines, neural networks, ensemble learning, and the like.
　（２－３）第１記憶部
　第１記憶部１３は、第１情報及び第２情報を記憶する。第１情報は、部屋名と空気調和機の要否とが関連付けられている。第１情報は、例えば図３に示すように、複数の部屋名と、各部屋名に基づく空気調和機の要否とが挙げられたリストである。 (2-3) First storage unit The first storage unit 13 stores the first information and the second information. The first information is related to the room name and the necessity of the air conditioner.

The level regarding the high and low of the heat load indicates a criterion of whether the heat load is relatively high or low, and may indicate whether the heat load is high or low as shown in FIG. 4, or may indicate an evaluated numerical value. ..
　（２－４）判断部
　判断部１４は、抽出部１２で抽出した情報から部屋名及びオブジェクトの少なくとも一方を識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。 (2-4) Judgment unit The judgment unit 14 identifies at least one of the room name and the object from the information extracted by the extraction unit 12, and whether or not the predetermined area in the building is an area requiring an air conditioner from the identification result. To judge.
　具体的には、判断部１４は、抽出部１２で抽出した文字の情報から部屋名を識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。また、判断部１４は、抽出部１２で抽出した線の情報からオブジェクトを識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。また、判断部１４は、抽出部１２で抽出した線の情報から部屋名を識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。また、判断部１４は、抽出部１２で抽出した文字の情報及び線の情報から部屋名を識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。 Specifically, the determination unit 14 identifies the room name from the character information extracted by the extraction unit 12, and determines whether or not the predetermined area in the building is an area requiring an air conditioner from the identification result. Further, the determination unit 14 identifies the object from the line information extracted by the extraction unit 12, and determines whether or not the predetermined area in the building is an area requiring an air conditioner from the identification result. Further, the determination unit 14 identifies the room name from the line information extracted by the extraction unit 12, and determines whether or not the predetermined area in the building is an area requiring an air conditioner from the identification result. Further, the determination unit 14 identifies the room name from the character information and the line information extracted by the extraction unit 12, and determines whether or not the predetermined area in the building is an area requiring an air conditioner from the identification result. ..
　ここで、オブジェクトとは、所定エリアを認識するためのものである。詳細には、オブジェクトは、所定エリアの境界を識別するためのもの、及び／または、所定エリアの熱負荷を演算するためのものである。具体例を挙げると、オブジェクトは、ドア、柱、梁、エレベータ、エレベータホール、椅子、机、給湯装置、エントランス、窓、壁及びトイレの少なくとも１つである。 Here, the object is for recognizing a predetermined area. Specifically, the object is for identifying the boundary of a predetermined area and / or for calculating the heat load of the predetermined area. To give a specific example, an object is at least one of a door, a pillar, a beam, an elevator, an elevator hall, a chair, a desk, a hot water supply device, an entrance, a window, a wall, and a toilet.
　判断部１４は、オブジェクトを識別して、識別されたオブジェクトから、建物内の所定エリアが空気調和機の必要なエリアか否かを判断してもよい。また判断部１４は、オブジェクトから識別結果として部屋名を取得して、建物内の所定エリアが空気調和機の必要なエリアか否かを判断してもよい。 The determination unit 14 may identify an object and determine from the identified object whether or not a predetermined area in the building is an area requiring an air conditioner. Further, the determination unit 14 may acquire a room name as an identification result from the object and determine whether or not a predetermined area in the building is an area requiring an air conditioner.
　識別されたオブジェクトから空気調和機の必要か否かを判断する例を挙げる。オブジェクトとして給湯装置が識別されると、判断部１４は、給湯装置は熱負荷が大きいので、空気調和機が必要なエリアと判断する。 Here is an example of determining whether or not an air conditioner is necessary from the identified object. When the hot water supply device is identified as an object, the determination unit 14 determines that the hot water supply device has a large heat load and therefore is an area where an air conditioner is required.
　オブジェクトから識別結果として部屋名を取得する例を挙げる。オブジェクトとして、机及び椅子が識別されると、所定エリアは会議室、事務室などの居室という識別結果を取得する。オブジェクトとして便器が識別されると、所定エリアはトイレという識別結果を取得する。オブジェクトとして階段が識別されると、所定エリアは階段室という識別結果を取得する。オブジェクトとしてエレベータが識別されると、所定エリアはエレベータという識別結果を取得する。オブジェクトとしてエレベータが識別されると、エレベータ前の所定エリアはエレベータホールであるという識別結果を取得する。オブジェクトとして、湯沸かし器が識別されると、所定エリアは給湯室という識別結果を取得する。 Here is an example of acquiring the room name as the identification result from the object. When a desk and a chair are identified as objects, the predetermined area acquires the identification result of a living room such as a conference room or an office. When the toilet bowl is identified as an object, the predetermined area acquires the identification result of the toilet. When the staircase is identified as an object, the predetermined area acquires the identification result of the staircase. When an elevator is identified as an object, the predetermined area acquires the identification result of the elevator. When the elevator is identified as an object, the identification result that the predetermined area in front of the elevator is an elevator hall is acquired. When the water heater is identified as an object, the predetermined area acquires the identification result of the hot water supply room.
　判断部１４は、線種及び寸法値の少なくとも一方に基づいて、部屋の区切と寸法線とを区別して所定エリアを画定する。例えば図２の紙図面を変換した画像データにおいて、領域Ｒ２は壁であり、領域Ｒ３はドアであることを考慮して、所定エリアを画定する。画定したエリアについて、判断部１４は空気調和機の要否を判断する。 The determination unit 14 defines a predetermined area by distinguishing between the room division and the dimension line based on at least one of the line type and the dimension value. For example, in the image data obtained by converting the paper drawing of FIG. 2, a predetermined area is defined in consideration that the area R2 is a wall and the area R3 is a door. The determination unit 14 determines the necessity of the air conditioner for the defined area.
　判断部１４は、識別結果としての部屋名から空気調和機が必要か否かの判断が難しいときに、別の識別結果を用いてもよい。具体的には、オブジェクトとして窓に関する窓情報を識別する。この場合、判断部１４は、所定エリアの部屋名及び窓情報を識別して、空気調和機の必要なエリアか否かを判断する。部屋名から空気調和機が必要か否かの判断が難しいときに、例えば、窓が有れば空気調和機が不要なエリアと判断し、窓が無ければ空気調和機が必要なエリアと判断する。 The determination unit 14 may use another identification result when it is difficult to determine whether or not an air conditioner is necessary from the room name as the identification result. Specifically, it identifies window information about a window as an object. In this case, the determination unit 14 identifies the room name and window information of the predetermined area, and determines whether or not the area requires an air conditioner. When it is difficult to judge from the room name whether or not an air conditioner is necessary, for example, if there is a window, it is judged that the air conditioner is unnecessary, and if there is no window, it is judged that the air conditioner is necessary. ..
　また、判断部１４は、識別結果としての部屋名から空気調和機が必要か否かの判断が難しいときに、第１記憶部１３に格納された第１情報を用いてもよい。具体的には、判断部１４は、第１記憶部１３から第１情報を読み出して、第１情報に基づいて識別した部屋名から空気調和機の必要なエリアか否かを判断する。 Further, the determination unit 14 may use the first information stored in the first storage unit 13 when it is difficult to determine whether or not an air conditioner is necessary from the room name as the identification result. Specifically, the determination unit 14 reads the first information from the first storage unit 13 and determines whether or not the area is a necessary area for the air conditioner from the room name identified based on the first information.
　本実施形態の判断部１４は、フロア情報と部屋名とを関連付けて、空気調和機の必要なエリアか否かを判断する。例えば、抽出部１２において、文字として「１階平面図」などのフロア情報と、「会議室」などの部屋名と、を抽出できる場合には、判断部１４は、１階会議室が空気調和機の必要なエリアか否かを判断する。抽出部１２でフロア情報を抽出できると、同じ部屋名であっても、１階か高層階かを考慮して、空気調和機の要否を判断できる。 The determination unit 14 of the present embodiment associates the floor information with the room name and determines whether or not the area requires an air conditioner. For example, if the extraction unit 12 can extract floor information such as "first floor plan" and a room name such as "meeting room" as characters, the determination unit 14 determines that the first floor conference room is in air conditioner. Determine if it is in the required area of the aircraft. If the floor information can be extracted by the extraction unit 12, the necessity of the air conditioner can be determined in consideration of whether the room name is the first floor or the upper floor.
　建物の改修などの更新物件の場合、過去（更新前）の空気調和機に関する情報を利用してもよい。具体的には、判断部１４は、オブジェクトとして空気調和機を識別して、識別結果から建物内の所定エリアが空気調和機の必要なエリアか否かを判断する。更新物件の場合、判断部１４は、過去の同じエリアに空気調和機があったことを識別すると、更新後も空気調和機が必要であると判断する。また判断部１４は、過去の同じエリアに空気調和機がなかったことを識別すると、更新後も空気調和機が不要であると判断する。 In the case of a renewal property such as a building renovation, information on past (before renewal) air conditioners may be used. Specifically, the determination unit 14 identifies the air conditioner as an object, and determines whether or not the predetermined area in the building is an area requiring the air conditioner from the identification result. In the case of a renewed property, if the determination unit 14 identifies that there was an air conditioner in the same area in the past, it determines that the air conditioner is still required after the renewal. Further, when the determination unit 14 identifies that there was no air conditioner in the same area in the past, it determines that the air conditioner is unnecessary even after the update.
　ここで、判断部１４が識別結果として部屋名を取得した場合に、建物内の所定エリアが空気調和機の必要なエリアか否かを判断する例を挙げる。所定エリアが会議室、事務室などの居室という識別結果の場合には、判断部１４は、部屋名から空気調和機の必要なエリアであると判断する。所定エリアが階段室、エレベータ（ＥＶ）、パイプスペース（ＰＳ）、エレクトリックパイプスペース（ＥＰＳ）、エレクトリックスペース（ＥＳ）またはダクトスペース（ＤＳ）であるという識別結果の場合には、判断部１４は、部屋名から空気調和機が不要なエリアであると判断する。所定エリアがトイレ、エレベータホール及び給湯室の場合には、判断部１４は、部屋名のみから空気調和機が必要か否かの判断をしない。この場合、判断部１４は、例えば、第１記憶部１３から部屋名と空気調和機の要否とがリストアップされた第１情報を読み出して、第１情報に基づいて空気調和機が必要か否かを判断する。 Here, an example of determining whether or not a predetermined area in the building is an area requiring an air conditioner when the determination unit 14 acquires the room name as the identification result will be given. When the predetermined area is an identification result of a living room such as a conference room or an office, the determination unit 14 determines from the room name that the area requires an air conditioner. In the case of the identification result that the predetermined area is a staircase, an elevator (EV), a pipe space (PS), an electric pipe space (EPS), an electric space (ES) or a duct space (DS), the determination unit 14 determines. From the room name, it is judged that the area does not require an air conditioner. When the predetermined area is a toilet, an elevator hall, or a hot water supply room, the determination unit 14 does not determine whether or not an air conditioner is necessary only from the room name. In this case, for example, the determination unit 14 reads out the first information in which the room name and the necessity of the air conditioner are listed from the first storage unit 13, and whether the air conditioner is necessary based on the first information. Judge whether or not.
　（２－５）決定部
　決定部２１は、判断部１４で空気調和機の必要なエリアと判断されたエリアを、空気調和機の必要なエリアと決定する。 (2-5) Determination unit The determination unit 21 determines an area determined by the determination unit 14 as an area requiring an air conditioner as an area requiring an air conditioner.
