On the basis of the floor plan data for the plurality of buildings stored in the equipment floor plan database (28), a similarly-positioned-equipment extraction unit (38) extracts, as an equipment with maintenance priority, a piece of equipment of the identical type as the malfunctioning piece of equipment and similar to the malfunctioning piece of equipment in terms of environmental information and satisfying a prescribed condition.

Description

設備保守支援システムEquipment maintenance support system
　本発明は、建物に設置された設備の保守業務を支援するシステムに関する。 The present invention relates to a system that supports maintenance work of equipment installed in a building.
　ビル等の建物をはじめとする不動産の運営・管理を行う、いわゆるファシリティマネジメントサービスには、管理対象の建物に設置された設備を正常な（あるいは最適な）状態に保つための保守業務が含まれる。保守対象の設備（空調、給排水、照明、昇降機、防犯等）は多岐に亘ることから、予め定められた優先順位に沿って保守業務が遂行される。例えば、故障や異常の発生割合が相対的に高い設備（優先保守設備）が優先的に保守対象となる。 The so-called facility management service, which manages and manages real estate including buildings, includes maintenance work to keep the equipment installed in the managed building in a normal (or optimal) state. . Maintenance facilities (air conditioning, water supply / drainage, lighting, elevators, crime prevention, etc.) are diverse, and maintenance work is performed according to a predetermined priority order. For example, a facility (priority maintenance facility) with a relatively high occurrence rate of failure or abnormality is preferentially maintained.
　例えば特許文献１では、資産設備の構成、形状などの変化値（ヘルスインデックス）を算出して、故障発生部位の抽出や故障発生予測を行っている。そして、地理的情報や天候などの環境情報とも連携して、点検・保全作業の優先順位を定めている。 For example, in Patent Document 1, a change value (health index) such as the configuration and shape of an asset facility is calculated, and a failure occurrence part is extracted and a failure occurrence prediction is performed. The priority of inspection / maintenance work is determined in cooperation with geographical information and environmental information such as weather.
　また特許文献２及び特許文献３では、所定の設備の運転状態が管理目標に到達しない場合に、設備の運転状態と環境状態によりその原因を推論している。特許文献４では、所定の設備の運転状態が管理目標値を達成できない場合に、それまで収集したデータをもとに原因を推論している。 In Patent Document 2 and Patent Document 3, when the operation state of a predetermined facility does not reach the management target, the cause is inferred from the operation state and environmental state of the facility. In patent document 4, when the operation state of a predetermined facility cannot achieve the management target value, the cause is inferred based on the data collected so far.

　ところで、異常発生のおそれの高い優先保守設備の抽出に当たり、実際に異常が発生した設備と同一機種の設備は優先保守設備の候補となり得る。さらにその絞込み条件として、異常発生設備と設置環境が近いことが挙げられる。例えば空調設備を例に挙げると、異常が発生した空調設備が設置された部屋と同一の機能を備えた部屋（例えば倉庫）において、埃の舞い上がり等による空調設備異常が生じ易いという、共通の異常発生原因が存在する。また異常が発生した空調設備が設置された部屋と同一面積の部屋において、温度調整機能の不全（例えば冷やし過ぎや冷房不足）等の、共通の異常発生原因が存在する。 By the way, in extracting priority maintenance equipment with a high possibility of occurrence of an abnormality, equipment of the same model as the equipment where the abnormality actually occurred can be a candidate for priority maintenance equipment. Furthermore, the narrowing condition is that the facility where the abnormality occurs and the installation environment are close. For example, taking air conditioning equipment as an example, a common abnormality that air conditioning equipment abnormalities are likely to occur due to dust soaring in a room (for example, a warehouse) having the same function as the room where the air conditioning equipment where the abnormality occurred is installed. There is a cause. Further, in a room having the same area as the room where the air conditioner in which an abnormality has occurred is installed, there are common causes of abnormalities such as a temperature adjustment function failure (for example, excessive cooling or insufficient cooling).
　このような場合に、各ビルのファシリティマネジメントサービスを統括する統合管理システムから、異常発生設備を有するビルに対して、異常発生設備及びこれが設置された環境情報（例えば部屋名や部屋面積等）を問い合わせることが考えられる。さらにこれを踏まえ、サービス対象の各ビルに対して異常発生設備と同一の設備及び同一の環境情報を問い合わせることが考えられる。しかしながら、このような問い合わせをサービス提供対象の全てのビルに対して行うことになると、その業務負担は過大となる。そこで本発明は、異常発生設備及びその設置環境情報の取得ならびにこれと同一または類似の設備及び設置環境情報の取得に当たり、その業務負荷を軽減可能な、設備保守支援システムを提供することを目的とする。 In such a case, from the integrated management system that supervises the facility management service of each building, for the building having the abnormality generating facility, the abnormality generating facility and the environmental information (for example, the room name, the room area, etc.) It is possible to inquire. Furthermore, based on this, it is conceivable to inquire about the same equipment and the same environmental information as the anomaly generating equipment for each building to be serviced. However, if such inquiries are made to all the buildings to which the service is to be provided, the business burden becomes excessive.

FIG. 1 illustrates a configuration diagram of a facility management service including an equipment maintenance support system 10 according to the present embodiment. The facility maintenance support system 10 can communicate with a plurality of buildings 12A, 12B, and 12C that receive the facility management service via the network 14.
　建物１２Ａ～１２Ｃがビルや大型商業施設等である場合、設備保守支援システム１０はいわゆるビル・エネルギー・マネージメント・システム（ＢｕｉｌｄｉｎｇＥｎｅｒｇｙ Ｍａｎａｇｅｍｅｎｔ Ｓｙｓｔｅｍ、ＢＥＭＳ）の一部として構成される。後述するように、設備保守支援システム１０は、建物１２Ａ，１２Ｂ，１２Ｃに設置された設備の保守業務を支援する。 When the buildings 12A to 12C are buildings or large commercial facilities, the equipment maintenance support system 10 is configured as a part of a so-called building energy management system (Building Energy Management System, BEMS). As will be described later, the equipment maintenance support system 10 supports maintenance work for equipment installed in the buildings 12A, 12B, and 12C.
　設備保守支援システム１０は、例えば計算機システム（コンピュータ）を含んで構成される。設備保守支援システム１０は、ＣＰＵ１６（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）、メモリ１８、入力部２０、表示部２２、及び入出力インターフェース２４がシステムバスを介して接続される。 The equipment maintenance support system 10 includes, for example, a computer system (computer). In the equipment maintenance support system 10, a CPU 16 (Central Processing Unit), a memory 18, an input unit 20, a display unit 22, and an input / output interface 24 are connected via a system bus.
　入力部２０は、例えばキーボードやマウス等で構成され、設備保守支援システム１０の運用者等が各種設備の保守計画に関する各種情報を入力可能となっている。表示部２２は例えばＬＣＤ等で構成され、ＣＰＵ１６の演算処理結果やメモリ１８に記憶された各種データベースの記憶内容を表示可能となっている。また入出力インターフェース２４は、ネットワーク１４を介して建物１２Ａ～１２Ｃと通信可能となっている。なお図面の都合上、図１では、設備保守支援システム１０と接続された建物１２は建物１２Ａ～１２Ｃの３棟のみであるが、より多くの建物１２と接続されていてよい。 The input unit 20 includes, for example, a keyboard and a mouse, and an operator of the equipment maintenance support system 10 can input various information related to maintenance plans for various equipment. The display unit 22 is constituted by an LCD, for example, and can display the calculation processing result of the CPU 16 and the stored contents of various databases stored in the memory 18. The input / output interface 24 can communicate with the buildings 12A to 12C via the network 14. For convenience of drawing, in FIG. 1, the building 12 connected to the facility maintenance support system 10 is only three buildings 12A to 12C, but may be connected to more buildings 12.
　メモリ１８は、例えばＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）、ＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）等のメモリや、ハードディスク等のストレージデバイスを含む、揮発性及び不揮発性メモリ（記憶媒体）から構成される。後述するように、メモリ１８には、コンピュータを設備保守支援システム１０として機能させるプログラムが記憶されている。なお、当該プログラムが記憶された、ＣＤ－ＲＯＭやＤＶＤ等の記憶媒体を読み込むことで、コンピュータを設備保守支援システム１０として機能させてもよい。また、メモリ１８には図２に示すように警報詳細データベース２６、設備図面データベース２８、及び保守管理スケジュールデータベース３０が構成される。 The memory 18 includes, for example, a volatile and non-volatile memory (storage medium) including a memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory) and a storage device such as a hard disk. As will be described later, the memory 18 stores a program that causes a computer to function as the equipment maintenance support system 10. Note that the computer may function as the facility maintenance support system 10 by reading a storage medium such as a CD-ROM or DVD in which the program is stored. The memory 18 includes an alarm detail database 26, an equipment drawing database 28, and a maintenance management schedule database 30 as shown in FIG.
　警報詳細データベース２６に記憶されたデータの説明に先立ち、図３には、建物１２Ａ～１２Ｃから発報される警報の詳細が例示されている。当該警報（ｘＹＹＺＺＺ）には、建物の識別情報（ビルＩＤ：ｘ）、異常が発生した設備（以下適宜、異常発生設備と記載する）の識別情報（設備ＩＤ：ＹＹ）、及び、設備ごとに定められたエラーコード（ＺＺＺ）が含められている。 Prior to the description of the data stored in the alarm details database 26, FIG. 3 illustrates details of alarms issued from the buildings 12A to 12C. The alarm (xYYZZZZ) includes building identification information (building ID: x), identification information (equipment ID: YY) of equipment in which an abnormality has occurred (hereinafter referred to as an abnormality-occurring equipment as appropriate), and for each equipment A predetermined error code (ZZZ) is included.
　図４には、警報詳細データベース２６に記憶されたデータが例示されている。例えば警報詳細データベース２６に記憶されたデータは、建物（ビル）単位で記憶される。さらにビル単位のデータにおいて、警報コード（ＡＡ００１等）とこれに対応する異常内容（温度異常等）や異常発生設備名（空調Ａ等）が記憶されている。例えば警報の内容が、ｘＹＹＺＺＺ＝ａＡＡ００１である場合、警報詳細データベース２６を参照することで、ビルａの設備ＡＡ（空調Ａ）において異常００１（温度異常）が発生したことが判明される。 FIG. 4 illustrates data stored in the alarm detail database 26. For example, the data stored in the alarm detail database 26 is stored in units of buildings. Further, in the data for each building, an alarm code (AA001, etc.), an abnormality content (temperature abnormality, etc.) corresponding to the alarm code, and an abnormality facility name (air conditioning A, etc.) are stored. For example, when the content of the alarm is xYYZZZZ = aAA001, referring to the alarm detail database 26, it is found that an abnormality 001 (temperature abnormality) has occurred in the facility AA (air conditioning A) of the building a.
　設備図面データベース２８は、複数の建物１２Ａ～１２Ｃの図面情報が記憶される。図２では設備図面データベース２８は設備保守支援システム１０内に格納された、いわゆるインハウス型のデータベースであるが、設備保守支援システム１０の外部に設けられ、ネットワークを介して接続可能な、いわゆるクラウド型のデータベースであってもよい。 The facility drawing database 28 stores drawing information of a plurality of buildings 12A to 12C. In FIG. 2, the equipment drawing database 28 is a so-called in-house database stored in the equipment maintenance support system 10, but is a so-called cloud that is provided outside the equipment maintenance support system 10 and can be connected via a network. It may be a database of types.
　図５、図６には、設備図面データベース２８に記憶されたデータが例示されている。図５は、例えば２Ｄ－ＣＡＤや３Ｄ－ＣＡＤによる平面図データが例示されている。建物１２Ａ～１２Ｃが複数階に及ぶ場合、平面図データは階ごとに記憶される。さらにこれら複数階に亘る平面図データは、建物別に記憶される。この平面図データには、一般的な平面図と同様にして、所定階（フロア）の部屋割りや部屋を区画する壁の寸法（長さや壁の厚さを含む）、部屋名が含まれる。さらに各部屋に設置される設備のシンボル及び名称が含まれる。加えて設備から延設される配線や配管の経路も記載されている。また、図５には記載を省略しているが、各平面図には方角も記載されている。さらに、３Ｄ－ＣＡＤデータによれば、建物１２の３次元の躯体情報（躯体を構成する壁の寸法など）が取得可能となる。 5 and 6 illustrate data stored in the facility drawing database 28. FIG. 5 illustrates, for example, plan view data by 2D-CAD or 3D-CAD. When the buildings 12A to 12C extend over a plurality of floors, the plan data is stored for each floor. Furthermore, the plan view data over the plurality of floors is stored for each building. This plan view data includes the room allocation of a predetermined floor (floor), the dimensions of the walls (including the length and wall thickness), and the room name as in the case of a general plan view. Furthermore, the symbols and names of the facilities installed in each room are included. In addition, wiring and piping routes extending from the facility are also described. Moreover, although description is abbreviate | omitted in FIG. 5, the direction is also described in each top view. Furthermore, according to the 3D-CAD data, it is possible to acquire three-dimensional frame information (such as dimensions of walls constituting the frame) of the building 12.
　図６には、設備図面データベース２８に記憶されたデータとして、ＢＩＭ（Ｂｕｉｌｄｉｎｇ　Ｉｎｆｏｒｍａｔｉｏｎ　Ｍｏｄｅｌｉｎｇ）データが例示されている。ＢＩＭは既知の技術であることからここでは簡単に説明する。ＢＩＭでは設備や部屋、壁、柱等のオブジェクトを配置し、仮想的に３次元の建物が構築される。各オブジェクトには名称、寸法、材料、機種、価格、納期、設置部屋等の属性情報が入力される。上記属性情報のうち例えば寸法は、壁オブジェクトを例に取ると、設置階（１階）、仕上げ厚（ｘｘｍｍ）、幅（＊＊ｍ）高さ等が入力される。また部屋オブジェクトを例に取ると、設置階（１階）、面積（１００ｍ＾２）、高さ等が入力される。このようなオブジェクトの情報から、建物１２の３次元の躯体情報（躯体を構成する壁の寸法など）が取得可能となる。 FIG. 6 illustrates BIM (Building Information Modeling) data as data stored in the facility drawing database 28. Since BIM is a known technique, it will be briefly described here. In BIM, objects such as equipment, rooms, walls, and pillars are arranged to virtually construct a three-dimensional building. Each object is input with attribute information such as name, dimensions, material, model, price, delivery date, installation room, and the like. In the attribute information, for example, when a wall object is taken as an example, an installation floor (first floor), a finishing thickness (xx mm), a width (** m) height, and the like are input. Taking a room object as an example, the installation floor (first floor), area (100 m 2), height, and the like are input. From such object information, the three-dimensional frame information of the building 12 (such as the dimensions of the walls constituting the frame) can be acquired.
　保守管理スケジュールデータベース３０には、建物１２Ａ～１２Ｃにおける各種設備の保守点検スケジュールが記憶されている。後述するように、優先保守設備が抽出された際には、この保守点検スケジュールが変更され、優先保守設備の保守スケジュールが割り込み挿入される。 The maintenance management schedule database 30 stores maintenance inspection schedules for various facilities in the buildings 12A to 12C. As will be described later, when the priority maintenance facility is extracted, the maintenance inspection schedule is changed, and the maintenance schedule of the priority maintenance facility is interrupted and inserted.
　図１に戻り、ＣＰＵ１６は、メモリ１８やＣＤ－ＲＯＭやＤＶＤ等の記憶媒体に記憶されたプログラムの実行に伴い、図２等に示すように、仮想的に複数の機能部が構築される。具体的には、ＣＰＵ１６は、警報受信部３２、原因設備推定部３４、設備配置解析部３６、及び類似配置設備抽出部３８を備える。 Referring back to FIG. 1, the CPU 16 virtually constructs a plurality of functional units as shown in FIG. 2 and the like in accordance with the execution of the program stored in the storage medium such as the memory 18, CD-ROM, or DVD. Specifically, the CPU 16 includes an alarm receiving unit 32, a cause facility estimation unit 34, a facility layout analysis unit 36, and a similar layout facility extraction unit 38.
　警報受信部３２は、ネットワーク１４を介して建物１２Ａ～１２Ｃから発報された警報を受信する。受信した警報は原因設備推定部３４に送られる。原因設備推定部３４は、受信した警報のビルＩＤ、設備ＩＤ、及びエラーコードに対応するビル名、設備名、及び異常内容を警報詳細データベース２６から呼び出す。これらビル名、設備名、及び異常内容は表示部２２に送信される。またビル名及び設備名は設備配置解析部３６に送信される。 The alarm receiving unit 32 receives alarms issued from the buildings 12A to 12C via the network 14. The received alarm is sent to the cause facility estimation unit 34. The cause facility estimation unit 34 calls the building name, facility name, and abnormality content corresponding to the received building ID, facility ID, and error code from the alarm detail database 26. These building name, equipment name, and abnormality content are transmitted to the display unit 22. Further, the building name and the equipment name are transmitted to the equipment arrangement analyzing unit 36.
　図７には、設備配置解析部３６の詳細な機能ブロック図が例示されている。設備配置解析部３６は、発報元情報取得部４０、設備位置取得部４２、設置部屋取得部４４、及び部屋情報取得部４６を備える。 FIG. 7 illustrates a detailed functional block diagram of the facility arrangement analysis unit 36. The facility arrangement analysis unit 36 includes a report source information acquisition unit 40, a facility position acquisition unit 42, an installation room acquisition unit 44, and a room information acquisition unit 46.
　図８には、設備配置解析部３６による、異常発生設備の環境情報取得フローが例示されている。発報元情報取得部４０は、原因設備推定部３４から、警報発報元のビルＩＤ及び異常発生設備の設備名を取得する（Ｓ１０）。次に設備位置取得部４２は、設備図面データベース２８から、取得したビルＩＤと同一のビルであって、異常発生設備が含まれる階の図面データを取得する。 FIG. 8 illustrates an environment information acquisition flow of an abnormality occurrence facility by the facility arrangement analysis unit 36. The reporting source information acquisition unit 40 acquires the building ID of the alarm reporting source and the facility name of the abnormality occurrence facility from the cause facility estimation unit 34 (S10). Next, the facility position acquisition unit 42 acquires, from the facility drawing database 28, drawing data of a floor that is the same building as the acquired building ID and includes the abnormality occurrence facility.
　さらに設備位置取得部４２は、取得した階の図面データに基づいて、異常発生設備の環境情報を取得する。まず設備位置取得部４２は、異常発生設備の設置位置を取得する（Ｓ１２）。例えばＢＩＭデータの場合、設備オブジェクトの属性情報に３次元座標が含まれるので、これが設置位置として利用される。 Furthermore, the facility position acquisition unit 42 acquires environmental information of the facility where the abnormality has occurred based on the acquired floor plan data. First, the facility position acquisition unit 42 acquires the installation position of the abnormality occurrence facility (S12). For example, in the case of BIM data, since the three-dimensional coordinates are included in the attribute information of the equipment object, this is used as the installation position.
　また２次元ＣＡＤデータや３次元ＣＡＤデータでは、画像認識や文字認識に基づいて平面図上の異常発生設備を特定する。例えば図９に示されているように、異常発生設備が空調Ｂである場合、設備位置取得部４２は文字認識により空調Ｂを認識する。さらにテキスト「空調Ｂ」の直上にある空調機器のシンボルを画像認識する。次に平面図全体に対する異常発生設備の相対位置を求める。例えば平面図に記載された壁等の寸法から、２次元座標が取得できる。例えば平面図に記載された階の左下端を（０，０）として、寸法に基づいて空調Ｂの座標を求めることができる。 Also, in 2D CAD data and 3D CAD data, an anomaly generating facility on the plan view is specified based on image recognition and character recognition. For example, as illustrated in FIG. 9, when the abnormality occurrence facility is the air conditioner B, the facility position acquisition unit 42 recognizes the air conditioner B by character recognition. Further, the image of the symbol of the air conditioner immediately above the text “air conditioner B” is recognized. Next, the relative position of the abnormality occurrence facility with respect to the entire plan view is obtained. For example, two-dimensional coordinates can be acquired from the dimensions of a wall or the like described in the plan view. For example, the coordinates of the air conditioner B can be obtained based on the dimensions, with the lower left corner of the floor described in the plan view being (0, 0).
　次に設置部屋取得部４４は、異常発生設備の設置位置がどの部屋範囲に含まれるか解析し、その部屋名を取得する（Ｓ１４）。なお、部屋範囲とは、４方を壁で囲まれた空間を指す他に、打ち合わせスペース等のように一部が開放された空間範囲も含まれる。 Next, the installation room acquisition unit 44 analyzes which room range includes the installation position of the abnormality occurrence facility, and acquires the room name (S14). The room range refers to a space surrounded by walls on four sides, and also includes a space range partially opened such as a meeting space.
　例えばＢＩＭデータの場合、設備オブジェクトの属性情報に設置部屋情報（サーバ室等）が含まれており、これが部屋範囲の特定に利用される。また２次元ＣＡＤデータや３次元ＣＡＤデータでは、平面図に部屋名が明記されており、これを文字認識によって取得する。例えば図９に示されるように、異常発生設備が空調Ｂである場合、設置部屋取得部４４はテキスト「空調Ｂ」周辺であって、当該テキスト「空調Ｂ」とは線によって隔てられていないテキストを探索してテキスト「サーバ室」を取得する。加えて、テキスト「サーバ室」を囲む線を結んで図１０の太線で示すようにサーバ室等各部屋の境界を画定する。 For example, in the case of BIM data, installation room information (server room, etc.) is included in the attribute information of the equipment object, and this is used for specifying the room range. In the two-dimensional CAD data and the three-dimensional CAD data, the room name is specified in the plan view, and this is acquired by character recognition. For example, as shown in FIG. 9, in the case where the abnormality occurrence facility is air conditioning B, the installation room acquisition unit 44 is around the text “air conditioning B” and is not separated from the text “air conditioning B” by a line. To obtain the text “server room”. In addition, a line surrounding the text “server room” is connected to define the boundary of each room such as the server room as shown by a thick line in FIG.
　次に部屋情報取得部４６は、取得した部屋範囲の部屋面積Ａ０及び内周長Ｌ０を算出する（Ｓ１６）。例えばＢＩＭデータの場合、部屋情報取得部４６は、異常発生設備の属性情報から設置部屋情報を取得し、これと同一名の部屋オブジェクトを抽出する。さらにその部屋オブジェクトの属性情報から部屋面積Ａ０を取得する。また内周長Ｌ０について、部屋情報取得部４６は、異常発生設備の属性情報から設置部屋情報を取得し、これと同一の設置部屋情報を持つ壁オブジェクトを抽出する。壁オブジェクトには寸法情報が設定されているから、これを足し合わせることで部屋の内周長Ｌ０を求めることができる。 Next, the room information acquisition unit 46 calculates the room area A0 and the inner circumference L0 of the acquired room range (S16). For example, in the case of BIM data, the room information acquisition unit 46 acquires installation room information from the attribute information of the abnormality occurrence facility, and extracts a room object having the same name. Further, the room area A0 is acquired from the attribute information of the room object. For the inner circumference L0, the room information acquisition unit 46 acquires installation room information from the attribute information of the abnormality occurrence facility, and extracts a wall object having the same installation room information. Since dimension information is set for the wall object, the inner circumference L0 of the room can be obtained by adding the dimension information.
　また２次元ＣＡＤデータや３次元ＣＡＤデータの場合、平面図に記載された寸法をもとに内周長Ｌ０及び部屋面積Ａ０を得ることができる。 In the case of 2D CAD data or 3D CAD data, the inner peripheral length L0 and the room area A0 can be obtained based on the dimensions described in the plan view.
　上記のように、設備配置解析部３６によって異常発生設備の環境情報（部屋名、部屋面積、内周長）が取得されると、類似配置設備抽出部３８は、異常発生設備と同一機種であって、かつ、環境情報が所定の条件を満たし類似する設備を抽出して、これを優先保守設備に設定する。 As described above, when the environment information (room name, room area, inner circumference) of the abnormality occurrence facility is acquired by the facility arrangement analysis unit 36, the similar arrangement facility extraction unit 38 is the same model as the abnormality occurrence facility. In addition, a facility whose environmental information satisfies a predetermined condition is extracted and set as a priority maintenance facility.
　図１１には類似配置設備抽出部３８の機能ブロックが例示されている。この図に示されるように、類似配置設備抽出部３８は設備抽出部４８、設備位置取得部５０、設置部屋取得部５２、部屋情報取得部５４、部屋名比較部５６、及び面積／内周長比較部５８を備える。 FIG. 11 illustrates a functional block of the similar arrangement facility extraction unit 38. As shown in this figure, the similar arrangement facility extraction unit 38 includes a facility extraction unit 48, a facility position acquisition unit 50, an installation room acquisition unit 52, a room information acquisition unit 54, a room name comparison unit 56, and an area / inner circumference. A comparison unit 58 is provided.
　図１２には、類似配置設備抽出部３８による、優先保守設備の抽出フローが例示されている。設備抽出部４８は、設備配置解析部３６から、発報原因である異常発生設備の設備名及び当該異常発生設備が設置された部屋の部屋名、面積Ａ０、及び内周長Ｌ０を取得する（Ｓ２０）。また類似配置設備抽出部３８は、ファシリティマネジメントサービスの提供先である建物１２Ａ～１２Ｃ（客先ビル）の件数ｍを初期値１に設定する（Ｓ２２）。 FIG. 12 illustrates the extraction flow of priority maintenance equipment by the similar arrangement equipment extraction unit 38. The equipment extraction unit 48 acquires from the equipment arrangement analysis unit 36 the equipment name of the abnormality occurrence equipment that is the cause of the report, the room name of the room in which the abnormality occurrence equipment is installed, the area A0, and the inner peripheral length L0 ( S20). Also, the similar arrangement facility extraction unit 38 sets the number m of buildings 12A to 12C (customer buildings), which are facility management service providing destinations, to an initial value 1 (S22).
　次に類似配置設備抽出部３８は、類似判定対象の建物１２のビルＩＤを取得する（Ｓ２４）。設備抽出部４８は、設備図面データベース２８から、類似判定対象の建物１２の図面データを抽出し、未解析（類似未判定）かつ異常発生設備と同一名称の設備を抽出する（Ｓ２６）。ここで同一名称は完全同一である必要はなく、部分同一であってよい。例えば異常発生設備が空調Ｂの場合、テキスト「空調」を含む設備名を抽出する。 Next, the similar arrangement facility extraction unit 38 acquires the building ID of the similarity determination target building 12 (S24). The equipment extraction unit 48 extracts the drawing data of the building 12 subject to similarity determination from the equipment drawing database 28, and extracts equipment that has not been analyzed (similarity is not determined) and has the same name as the abnormality occurrence equipment (S26). Here, the same name does not need to be completely identical, and may be partially identical. For example, when the abnormality occurrence facility is air conditioning B, the facility name including the text “air conditioning” is extracted.
　例えば図面データがＢＩＭデータの場合、設備抽出部４８は、類似判定対象の建物１２のＢＩＭデータを設備図面データベース２８から抽出して、これに記録された設備オブジェクトを取得する。さらに設備名称にテキスト「空調」を含む設備を抽出する。 For example, when the drawing data is BIM data, the equipment extraction unit 48 extracts the BIM data of the building 12 to be subjected to similarity determination from the equipment drawing database 28, and acquires the equipment object recorded therein. Furthermore, the equipment including the text “air conditioning” in the equipment name is extracted.
　また図面データが２Ｄ－ＣＡＤデータや３Ｄ－ＣＡＤデータの場合、設備抽出部４８は、類似判定対象の建物１２のＣＡＤデータを設備図面データベース２８から抽出して、文字認識によりテキスト「空調」を探索する。さらに画像認識によりテキスト「空調」を含む文字列の直近にある設備シンボルを抽出する。 When the drawing data is 2D-CAD data or 3D-CAD data, the equipment extraction unit 48 extracts the CAD data of the building 12 subject to similarity determination from the equipment drawing database 28 and searches for the text “air-conditioning” by character recognition. To do. Furthermore, the equipment symbol nearest to the character string including the text “air-conditioning” is extracted by image recognition.
　設備抽出部４８は、上記のようにして抽出された設備の、類似判定対象の建物における総台数ｚを求める。さらに台数ｋを初期値１に設定する（Ｓ２８）。なお以下では、適宜、抽出された設備を「判定対象設備」と記載する。または、これら抽出された設備は優先保守設備の候補と成り得るため、「抽出候補設備」とも記載する。両者は同一の設備を指し、要するに異常発生設備と同一機種の設備を指す。 The facility extraction unit 48 obtains the total number z of the facilities extracted as described above in the building subject to similarity determination. Further, the number k is set to an initial value 1 (S28). Hereinafter, the extracted equipment is referred to as “determination target equipment” as appropriate. Alternatively, since these extracted facilities can be candidates for priority maintenance facilities, they are also referred to as “extraction candidate facilities”. Both refer to the same equipment, in other words, the equipment of the same model as the equipment where the abnormality occurred.
　設備位置取得部５０は、判定対象設備（抽出候補設備）が設置された階の図面データを取得する。さらに設備位置取得部５０は、取得した階の図面データに基づいて、判定対象設備（抽出候補設備）の設置位置を取得する（Ｓ３０）。この設置位置の取得では、設備配置解析部３６の設備位置取得部４２による処理と同様の処理が実行される。具体的には図８のステップＳ１２と同様の処理が実行される。 The facility position acquisition unit 50 acquires drawing data of the floor where the determination target facility (extraction candidate facility) is installed. Furthermore, the facility position acquisition unit 50 acquires the installation position of the determination target facility (extraction candidate facility) based on the acquired floor plan data (S30). In the acquisition of the installation position, processing similar to the processing by the equipment position acquisition unit 42 of the equipment arrangement analysis unit 36 is executed. Specifically, the same process as step S12 of FIG. 8 is executed.
　次に設置部屋取得部５２は、判定対象設備の設置位置がどの部屋範囲に含まれるか解析し、その部屋名を取得する（Ｓ３２）。このステップは、設備配置解析部３６の設置部屋取得部４４による処理と同様の処理が実行される。具体的には図８のステップＳ１４と同様の処理が実行される。 Next, the installation room acquisition unit 52 analyzes which room range includes the installation position of the determination target equipment, and acquires the room name (S32). In this step, the same processing as the processing by the installation room acquisition unit 44 of the equipment arrangement analysis unit 36 is executed. Specifically, the same processing as step S14 in FIG. 8 is executed.
　次に部屋情報取得部５４は、取得した部屋範囲の部屋面積Ａ＿ｍｋ及び内周長Ｌ＿ｍｋを算出する（Ｓ３４）。なおサフィックスｍはビル番号、サフィックスｋは設備番号を示す。このステップは、設備配置解析部３６の部屋情報取得部４６による処理と同様の処理が実行される。具体的には図８のＳ１６と同様の処理が実行される。 Next, the room information acquisition unit 54 calculates the room area A_mk and the inner peripheral length L_mk of the acquired room range (S34). The suffix m indicates a building number, and the suffix k indicates an equipment number. In this step, the same processing as the processing by the room information acquisition unit 46 of the equipment arrangement analysis unit 36 is executed. Specifically, the same processing as S16 in FIG. 8 is executed.
　次に部屋名比較部５６は、異常発生設備の設置部屋と判定対象設備の設置部屋との部屋名が同一であるか否かを判定する（Ｓ３６）。ここで同一とは完全同一に限らずに、部分同一であってよい。例えば部屋名が「居室１」のように数字が割り振られている場合、テキスト「室」より前の文字列が同一であるものが抽出される。 Next, the room name comparison unit 56 determines whether or not the room names of the installation room of the abnormality occurrence facility and the installation room of the determination target equipment are the same (S36). Here, the same is not limited to being completely identical, but may be partially identical. For example, when a number is assigned such that the room name is “room 1”, those having the same character string before the text “room” are extracted.
　異常発生設備の設置部屋と判定対象設備の設置部屋との部屋名が同一であると判定されると、判定対象設備は類似環境に設置された設備として、つまり優先保守設備として記録される（Ｓ４２）。例えばこの判定結果は保守管理スケジュールデータベース３０に記録される。 When it is determined that the room name of the installation room of the abnormality occurrence facility and the installation room of the determination target facility are the same, the determination target facility is recorded as a facility installed in a similar environment, that is, as a priority maintenance facility (S42). ). For example, the determination result is recorded in the maintenance management schedule database 30.
　一方、異常発生設備の設置部屋と判定対象設備の設置部屋との部屋名が同一ではないと判定されると、面積／内周長比較部５８は、異常発生設備の設置部屋面積Ａ０と判定対象設備の設置部屋面積Ａ＿ｍｋとの差が、第１閾値差分Ａｔｈ以下であるか否かを判定する（Ｓ３８）。｜Ａ０－Ａ＿ｍｋ｜≦Ａｔｈである場合、つまり面積が同一または類似する場合、判定対象設備は類似環境に設置された設備として、つまり優先保守設備として記録される（Ｓ４２）。 On the other hand, when it is determined that the room names of the installation room of the abnormality occurrence facility and the installation room of the determination target facility are not the same, the area / inner circumference comparison unit 58 determines that the installation room area A0 of the abnormality generation facility is the determination target. It is determined whether or not the difference from the installation room area A_mk of the facility is equal to or less than the first threshold difference Ath (S38). When | A0−A_mk | ≦ Ath, that is, when the areas are the same or similar, the determination target equipment is recorded as equipment installed in a similar environment, that is, as priority maintenance equipment (S42).
　部屋面積が類似しない、つまり｜Ａ０－Ａ＿ｍｋ｜＞Ａｔｈである場合、面積／内周長比較部５８は、異常発生設備の設置部屋内周長Ｌ０と判定対象設備の設置部屋内周長Ｌ＿ｍｋとの差が、第２閾値差分Ｌｔｈ以下であるか否かを判定する（Ｓ４０）。｜Ｌ０－Ｌ＿ｍｋ｜≦Ｌｔｈである場合、つまり内周長が同一または類似する場合、判定対象設備は類似環境に設置された設備として、つまり優先保守設備として記録される（Ｓ４２）。 When the room areas are not similar, that is, | A0−A_mk |> Ath, the area / inner circumference comparison unit 58 determines that the installation room inner circumference L0 of the abnormality occurrence equipment and the installation room inner circumference L_mk of the determination target equipment It is determined whether or not the difference is equal to or smaller than the second threshold difference Lth (S40). When | L0−L_mk | ≦ Lth, that is, when the inner circumference is the same or similar, the determination target equipment is recorded as equipment installed in a similar environment, that is, as priority maintenance equipment (S42).
　部屋内周長が類似しない、つまり｜Ｌ０－Ｌ＿ｍｋ｜＞Ｌｔｈである場合、判定対象設備は優先保守設備には判定されない。類似配置設備抽出部３８は、設備番号ｋが末尾ｚであるか否かを判定し（Ｓ４４）、ｚに未到達の場合は設備番号ｋをインクリメントして（Ｓ４６）、ステップＳ３０まで戻る。 If the room inner perimeter is not similar, that is, | L0-L_mk |> Lth, the determination target facility is not determined as the priority maintenance facility. The similar arrangement facility extraction unit 38 determines whether or not the facility number k is the last z (S44). If the facility number k has not reached z, the facility number k is incremented (S46), and the process returns to Step S30.
　設備番号ｋが末尾ｚまで到達した場合、類似配置設備抽出部３８は、建物番号ｍが末尾ｎであるか否かを判定し（Ｓ４８）、ｎに未到達の場合は建物番号ｍをインクリメントして（Ｓ５０）、ステップＳ２４まで戻る。建物番号ｍが末尾ｎに到達した場合、フローが終了する。 When the equipment number k reaches the end z, the similar arrangement equipment extraction unit 38 determines whether the building number m is the end n (S48). If n is not reached, the building number m is incremented. (S50), the process returns to step S24. When the building number m reaches the end n, the flow ends.
　類似配置設備抽出部３８によって抽出された優先保守設備は、表示部２２及び保守管理スケジュールデータベース３０に送られる。表示部２２には優先保守設備のリストと、異常発生設備の異常内容（図４参照）が表示される。またこれと併せて表示部には保守点検スケジュールが表示され、優先保守設備の保守スケジュールが繰り上げられる。例えば優先保守設備の保守・点検日が直近の日付に更新される。この更新スケジュールは入力部２０によって入力・変更されてもよい。 Priority maintenance equipment extracted by the similar arrangement equipment extraction unit 38 is sent to the display unit 22 and the maintenance management schedule database 30. The display unit 22 displays a list of priority maintenance facilities and an abnormality content (see FIG. 4) of the abnormality occurrence facility. At the same time, a maintenance inspection schedule is displayed on the display unit, and the maintenance schedule for the priority maintenance facility is advanced. For example, the maintenance / inspection date of the priority maintenance facility is updated to the latest date. This update schedule may be input / changed by the input unit 20.
　このように本実施形態に係る設備保守支援システム１０によれば、優先保守設備を設備図面データベース２８の図面データに基づいて抽出する。したがって、ファシリティサービス提供先の建物１２Ａ，１２Ｂ，・・・に問い合わせる必要がなくなり、相対的に作業負担が軽減される。 Thus, according to the equipment maintenance support system 10 according to the present embodiment, the priority maintenance equipment is extracted based on the drawing data of the equipment drawing database 28. Therefore, there is no need to make inquiries to the facility service providing destination buildings 12A, 12B,.
＜第２実施形態＞
　上述した実施形態では、第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈを定数として設定したが、部屋の優先度に応じてこれらの閾値を変更してもよい。図１３には第２実施形態に係る設備保守支援システム１０が例示されている。図２との違いは、設備保守支援システム１０が部屋重要度データベース６０を備える点にある。その他の構成は図２と同様であり、符号が重複する構成についてもその機能は同様である。以下では重複する符号やステップについては適宜説明を省略する。 Second Embodiment
In the embodiment described above, the first threshold difference Ath and the second threshold difference Lth are set as constants, but these thresholds may be changed according to the priority of the room. FIG. 13 illustrates an equipment maintenance support system 10 according to the second embodiment. The difference from FIG. 2 is that the facility maintenance support system 10 includes a room importance database 60. Other configurations are the same as those in FIG. 2, and the functions are the same for the configurations having the same reference numerals. In the following description, overlapping symbols and steps will not be described as appropriate.
　部屋重要度データベース６０に記憶されたデータを図１４に例示する。このデータベースには、部屋別に重要度が割り振られている。重要度は例えば実務に即して設定される。例えばサーバ室の空調が異常停止した場合、サーバの過熱を防ぐために速やかに修理が施される必要がある。このような事情に鑑みて、サーバ室の重要度は「大」に設定される。 The data stored in the room importance database 60 is illustrated in FIG. In this database, importance is assigned to each room. The importance is set in accordance with, for example, business. For example, when the air conditioning in the server room is abnormally stopped, it is necessary to promptly repair the server room in order to prevent overheating of the server. In view of such circumstances, the importance of the server room is set to “large”.
　優先保守設備の抽出に当たり、本実施形態では、図１５に例示されるように、類似配置設備抽出部３８が閾値設定部６１を備える。その他の機能部については図１１と同様であり、同図と同一の符号が付された機能部については同図の実施形態と同様であるため、以下では適宜記載を省略する。 In extracting the priority maintenance facility, in this embodiment, the similar-placement facility extraction unit 38 includes a threshold setting unit 61 as illustrated in FIG. The other functional units are the same as those in FIG. 11, and the functional units having the same reference numerals as those in FIG. 11 are the same as in the embodiment in FIG.
　図１６には、類似配置設備抽出部３８による優先保守設備の抽出フローが例示されている。図１２の違いは、ステップＳ３２，Ｓ３４間にステップＳ５２，Ｓ５４が挿入された点にある。その他の、図１２と同一の符号が付されたステップについては図１２の実施形態と同様であるため、以下では適宜説明を省略する。 FIG. 16 illustrates an example of the priority maintenance facility extraction flow by the similar arrangement facility extraction unit 38. 12 is that steps S52 and S54 are inserted between steps S32 and S34. Other steps denoted by the same reference numerals as those in FIG. 12 are the same as those in the embodiment in FIG.
　なお、部屋の重要度は優先保守設備の抽出に利用され、設備配置解析部３６による異常発生設備の環境情報取得フローには利用されない。したがって本実施形態においても、設備配置解析部３６については、図８と同様のフローが実行される。 It should be noted that the importance of the room is used for extracting the priority maintenance equipment, and is not used for the environment information acquisition flow of the abnormality occurrence equipment by the equipment arrangement analysis unit 36. Therefore, also in the present embodiment, the same flow as in FIG.
　優先保守設備の抽出に当たり、図１６を参照して、閾値設定部６１は、部屋重要度データベース６０を参照して、判定対象設備（抽出候補設備）の設置部屋の部屋名に対応する重要度を取得する（Ｓ５２）。さらに閾値設定部６１は、部屋重要度に応じて第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈを設定する（Ｓ５４）。 In extracting the priority maintenance facility, referring to FIG. 16, the threshold setting unit 61 refers to the room importance database 60 and determines the importance corresponding to the room name of the installation room of the determination target facility (extraction candidate facility). Obtain (S52). Further, the threshold setting unit 61 sets the first threshold difference Ath and the second threshold difference Lth according to the room importance (S54).
　定性的には、部屋の重要度が高いほど、第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈを拡大させる。つまり部屋の重要度が高いほど、類似と判定される範囲を広げる。例えば重要度「小」に比べて、重要度「中」の第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈを、１１０％増しとする。さらに重要度「中」に比べて、重要度「大」の第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈを、１１０％増しとする。このようにして部屋の重要度別に設定された第１閾値差分ＡｔｈがステップＳ３８で用いられ、第２閾値差分ＬｔｈがステップＳ４０で用いられる。 Qualitatively, the higher the importance of the room, the larger the first threshold difference Ath and the second threshold difference Lth. That is, the higher the importance of the room, the wider the range determined to be similar. For example, it is assumed that the first threshold difference Ath and the second threshold difference Lth of the importance “medium” are increased by 110% compared to the importance “small”. Further, the first threshold difference Ath and the second threshold difference Lth of the importance “large” are increased by 110% compared to the importance “medium”. The first threshold difference Ath set for each room importance in this way is used in step S38, and the second threshold difference Lth is used in step S40.
　このように、重要度の高い部屋ほど類似の範囲を拡大し、優先保守設備を相対的に緩いハードルで抽出することで、抽出漏れが防止可能となる。 In this way, it is possible to prevent the omission of extraction by expanding the similar range to the room with higher importance and extracting the priority maintenance equipment with relatively loose hurdles.
　また、部屋の重要度は、第１閾値差分Ａｔｈ及び第２閾値差分Ｌｔｈの設定に利用されるのみではなく、表示部２２に表示させてもよい。これは例えば保守管理スケジュールの更新に当たり、作業者の判断材料の一つとして利用される。 Also, the importance of the room may be displayed on the display unit 22 as well as used for setting the first threshold difference Ath and the second threshold difference Lth. This is used, for example, as one of the judgment materials for the operator when updating the maintenance management schedule.
＜第３実施形態＞
　上記の実施形態では、部屋の重要度を求めていたが、これに代えて、またはこれに加えて、異常発生設備の設置部屋との類似度を求めてもよい。図１７には第３実施形態に係る設備保守支援システム１０が例示されている。図１との違いは設備保守支援システム１０が移動履歴データベース６２を備える点にある。 <Third Embodiment>
In the above-described embodiment, the importance level of the room is obtained. However, instead of or in addition to this, the similarity degree with the installation room of the abnormality occurrence facility may be obtained. FIG. 17 illustrates an equipment maintenance support system 10 according to the third embodiment. The difference from FIG. 1 is that the equipment maintenance support system 10 includes a movement history database 62.
　図１８には、移動履歴データベース６２に記憶された移動履歴データが例示されている。移動履歴データは建物１２（ビル）ごとに記憶される。移動履歴データは、人物ＩＤ、時間、座標が記憶される。人物ＩＤは建物内の人物別に付与される。時間及び座標データにより、特定の人物がいつ、どこにいるのかが把握される。例えばオフィスビルの場合、社員の携帯端末と建物１２の中央監視装置等が通信することで、人物ＩＤ別の時間データ及び座標データを取得できる。取得した移動履歴データは、設備保守支援システム１０の移動履歴データベース６２に記憶される。 FIG. 18 illustrates movement history data stored in the movement history database 62.

In the above embodiment, the room name, the room area, the room inner circumference, the wall thickness, the wiring length, the pipe length, and the like are obtained, but other information on the direction (direction) of the room may be obtained. For example, it is determined whether or not the wall surrounding the room is an outer wall. As illustrated in FIG. 35, the outer wall refers to a wall exposed to the outside of the wall of the building 12, in other words, a wall that defines an extension of the plan view. Moreover, an inner wall refers to the wall outside an outer wall, for example, the wall extended in a floor.
　図３６には第９実施形態に係る設備保守支援システム１０が例示されている。図２との違いは、設備配置解析部３６の部屋情報取得部４６及び類似配置設備抽出部３８の部屋情報取得部５４が部屋名、面積、内周長の他に外壁／内壁の識別、及び外壁の方角を求める点にある。その他の構成については図２と同様であり、同図と同一の符号が付された構成については同図の実施形態と同様であるため、以下では適宜説明を省略する。 FIG. 36 illustrates an equipment maintenance support system 10 according to the ninth embodiment. The difference from FIG. 2 is that the room information acquisition unit 46 of the facility arrangement analysis unit 36 and the room information acquisition unit 54 of the similar arrangement facility extraction unit 38 identify the outer wall / inner wall in addition to the room name, area, and inner circumference length, and The point is to find the direction of the outer wall. The other configurations are the same as those in FIG. 2, and the configurations denoted by the same reference numerals as those in FIG. 2 are the same as those in the embodiment in FIG.
　図３７には、設備配置解析部３６による異常発生設備の環境情報取得フローが例示される。図８との違いは、ステップＳ１６の後にステップＳ８２～Ｓ８８が設けられた点にある。その他の、図８と同一の符号が付されたステップについては図８のフローと同様のため、以下では適宜説明を省略する。 FIG. 37 illustrates an environment information acquisition flow of an abnormality occurrence facility by the facility arrangement analysis unit 36. The difference from FIG. 8 is that steps S82 to S88 are provided after step S16. Other steps denoted by the same reference numerals as those in FIG. 8 are the same as those in the flow of FIG.
　ステップＳ１６にて異常発生設備の設置部屋の面積Ａ０及び内周長Ｌ０が算出されると、設備配置解析部３６の部屋情報取得部４６は異常発生設備を囲う壁から、外壁を抽出する（Ｓ８２）。これは例えばＢＩＭデータであってもＣＡＤデータであっても、平面図の画像認識から抽出可能である。外壁が存在しない場合、部屋の方角についてはＮｕｌｌ値（なし）が設定される（Ｓ８６）。 When the area A0 and the inner circumference L0 of the installation room of the abnormality occurrence facility are calculated in step S16, the room information acquisition unit 46 of the facility arrangement analysis unit 36 extracts the outer wall from the wall surrounding the abnormality occurrence facility (S82). ). This can be extracted from image recognition of a plan view, for example, BIM data or CAD data. If there is no outer wall, a null value (none) is set for the direction of the room (S86).
　一方、外壁ありと判定されると、外壁の向きに基づいて部屋の方角Ｄ０が定められる（Ｓ８８）。まず平面図に記載された方角を読み取って基準方角（例えば北）を得る。次に図３８に示すように、各外壁の方角を求める。外壁１を例に取ると、外壁１の両端を結ぶ線の中心点から、当該線に対する法線を求める。さらに基準方角に対する法線の角度Ｒ１を求める。角度Ｒ１は例えば時計回りに成す角度であってよい。 On the other hand, if it is determined that there is an outer wall, the direction D0 of the room is determined based on the direction of the outer wall (S88). First, the direction described in the plan view is read to obtain a reference direction (for example, north). Next, as shown in FIG. 38, the direction of each outer wall is obtained. Taking the outer wall 1 as an example, the normal to the line is obtained from the center point of the line connecting both ends of the outer wall 1. Further, a normal angle R1 with respect to the reference direction is obtained. The angle R1 may be an angle formed clockwise, for example.
　さらに角度Ｒ１に基づいて外壁１（及び部屋）の方角が求められる。例えば０°≦Ｒ１≦４５°または３１５°＜Ｒ１≦３６０°のとき、外壁１の方角は北と判定される。４５°＜Ｒ１≦１３５°のとき、外壁１の方角は東と判定される。１３５°＜Ｒ１≦２２５°のとき、外壁１の方角は南と判定される。２２５°＜Ｒ１≦３１５°のとき、外壁１の方角は西と判定される。異常発生設備の設置部屋を囲む壁に複数外壁が含まれる場合は、部屋の方角Ｄ０として複数の方角が判定される。 Further, the direction of the outer wall 1 (and the room) is obtained based on the angle R1. For example, when 0 ° ≦ R1 ≦ 45 ° or 315 ° <R1 ≦ 360 °, the direction of the outer wall 1 is determined to be north. When 45 ° <R1 ≦ 135 °, the direction of the outer wall 1 is determined to be east. When 135 ° <R1 ≦ 225 °, the direction of the outer wall 1 is determined to be south. When 225 ° <R1 ≦ 315 °, the direction of the outer wall 1 is determined to be west. When a plurality of outer walls are included in the wall surrounding the installation room of the abnormality occurrence facility, a plurality of directions are determined as the room direction D0.

　ステップＳ９２にて類似配置設備抽出部３８の設備抽出部４８は、異常発生設備の設備名、設置部屋名、部屋面積Ａ０、部屋内周長Ｌ０に加えて、部屋の方角Ｄ０を取得する。処理が進み、類似配置設備抽出部３８の部屋情報取得部５４は、判定対象設備（抽出候補設備）の設置部屋の外壁の有無を判定する（Ｓ９４）。この判定は設備配置解析部３６による異常発生設備の設置部屋の外壁判定と同様の処理（図３７のＳ８４）が実行される。 In step S92, the equipment extraction unit 48 of the similar arrangement equipment extraction unit 38 acquires the direction D0 of the room in addition to the equipment name of the abnormality occurrence equipment, the name of the installation room, the room area A0, and the room inner circumference L0. As the process proceeds, the room information acquisition unit 54 of the similar arrangement facility extraction unit 38 determines whether or not there is an outer wall of the installation room of the determination target facility (extraction candidate facility) (S94). For this determination, the same processing as the determination of the outer wall of the installation room of the abnormality occurrence facility by the facility arrangement analysis unit 36 (S84 in FIG. 37) is executed.
　外壁が存在しない場合、部屋の方角はなしに設定される（Ｓ９６）。一方、外壁有りと判定されると、部屋情報取得部５４は、部屋の方角Ｄ＿ｍｋを求める。このステップでは設備配置解析部３６による異常発生設備の設置部屋の方角判定と同様の処理（図３７のＳ８８）が実行される。 If there is no outer wall, the direction of the room is set to none (S96). On the other hand, if it is determined that there is an outer wall, the room information acquisition unit 54 obtains the direction D_mk of the room. In this step, the same processing (S88 in FIG. 37) as the direction determination of the installation room of the abnormality occurrence facility by the facility arrangement analysis unit 36 is executed.
　さらにステップが進み、判定対象設備の設置部屋の面積Ａ０と異常発生設備の設置部屋の面積Ａ＿ｍｋとの差が第１閾値差分Ａｔｈ以内か否かが判定される（Ｓ３８）。また判定対象設備の設置部屋の内周長Ｌ０と異常発生設備の設置部屋の内周長Ｌ＿ｍｋとの差が第２閾値差分Ｌｔｈ以内か否かが判定される（Ｓ４０）。 Further, the step further proceeds, and it is determined whether or not the difference between the area A0 of the installation room of the determination target equipment and the area A_mk of the installation room of the abnormality occurrence equipment is within the first threshold difference Ath (S38). Further, it is determined whether or not the difference between the inner peripheral length L0 of the installation target equipment installation room and the abnormality generating equipment installation room inner peripheral length L_mk is within the second threshold difference Lth (S40).
　｜Ａ０－Ａ＿ｍｋ｜≦Ａｔｈまたは｜Ｌ０－Ｌ＿ｍｋ｜≦Ｌｔｈである場合、異常発生設備の設置部屋の方角Ｄ＿ｍｋと判定対象設備の設置部屋の方角Ｄ０とが一致するか否かが判定される（Ｓ１００）。方角Ｄ＿ｍｋと方角Ｄ０が一致する場合、判定対象設備は異常発生設備と類似環境に設置された設備として保守管理スケジュールデータベース３０に記録される（Ｓ４２）。なお、方角Ｄ＿ｍｋ及び方角Ｄ０が複数ある場合は、一致する組み合わせが少なくとも一組あればよい。方角Ｄ＿ｍｋと方角Ｄ０がいずれも一致しない場合、｜Ａ０－Ａ＿ｍｋ｜≦Ａｔｈまたは｜Ｌ０－Ｌ＿ｍｋ｜≦Ｌｔｈであっても、判定対象設備は異常発生設備と類似環境には設置されていないと判定される。 If | A0−A_mk | ≦ Ath or | L0−L_mk | ≦ Lth, it is determined whether or not the direction D_mk of the installation room of the abnormality occurrence facility matches the direction D0 of the installation room of the determination target facility ( S100). When the direction D_mk and the direction D0 match, the determination target equipment is recorded in the maintenance management schedule database 30 as equipment installed in an environment similar to the abnormality occurrence equipment (S42). In addition, when there are a plurality of directions D_mk and directions D0, it is sufficient that there is at least one matching combination. When the direction D_mk and the direction D0 do not match, even if | A0−A_mk | ≦ Ath or | L0−L_mk | ≦ Lth, it is determined that the determination target facility is not installed in an environment similar to the abnormality occurrence facility Is done.

　ステップＳ１６にて異常発生設備の設置部屋の面積Ａ０及び内周長Ｌ０が算出されると、設備配置解析部３６の部屋情報取得部４６は異常発生設備の設置部屋の体積Ｖ０を算出する（Ｓ１０２）。例えばＢＩＭデータであれば部屋オブジェクトの属性情報として床面積および（床からの）天井高さが記録されているから、これから部屋体積Ｖ０が求められる。また３Ｄ－ＣＡＤデータにも床面積と（床からの）天井高さが記録されているので、これから部屋体積Ｖ０を求めることができる。 When the area A0 and the inner peripheral length L0 of the installation room of the abnormality occurrence facility are calculated in step S16, the room information acquisition unit 46 of the facility arrangement analysis unit 36 calculates the volume V0 of the installation room of the abnormality occurrence facility (S102). ). For example, in the case of BIM data, since the floor area and the ceiling height (from the floor) are recorded as the attribute information of the room object, the room volume V0 is obtained from this.

As the process proceeds, the room information acquisition unit 54 of the similar arrangement facility extraction unit 38 acquires the volume V_mk of the installation room of the determination target facility (S106). In this process, the same processing as the volume calculation of the installation room of the abnormality occurrence facility by the facility arrangement analysis unit 36 (S102 in FIG. 43) is executed.
　さらにステップが進み、判定対象設備の設置部屋の面積Ａ０と異常発生設備の設置部屋の面積Ａ＿ｍｋとの差が第１閾値差分Ａｔｈ以内か否かが判定される（Ｓ３８）。また判定対象設備の設置部屋の内周長Ｌ０と異常発生設備の設置部屋の内周長Ｌ＿ｍｋとの差が第２閾値差分Ｌｔｈ以内か否かが判定される（Ｓ４０）。 Further, the step further proceeds, and it is determined whether or not the difference between the area A0 of the installation room of the determination target equipment and the area A_mk of the installation room of the abnormality occurrence equipment is within the first threshold difference Ath (S38). Further, it is determined whether or not the difference between the inner peripheral length L0 of the installation target equipment installation room and the abnormality generating equipment installation room inner peripheral length L_mk is within the second threshold difference Lth (S40).
