Description

保守管理作業支援装置及び保守管理作業携帯端末Maintenance management work support device and maintenance management work mobile terminal
　本発明はビル設備の保守管理作業に用いられる保守管理作業支援装置及び保守管理作業携帯端末に関する。 The present invention relates to a maintenance management work support device and a maintenance management work mobile terminal used for maintenance management work of building equipment.
　ビル設備の保守管理作業では、外部システムが提供するＯＣＲ（Optical Character Recognition）などの情報処理サービスを利用する場合がある。外部システムは、通常、当該外部システムが提供するＡＰＩ（Application Programming Interface）を通じて利用するように構築されている。 In the maintenance work of building equipment, information processing services such as OCR (Optical Character Recognition) provided by an external system may be used. The external system is usually constructed to be used through an API (Application Programming Interface) provided by the external system.
　類似した情報処理サービスは、多くの場合、複数の外部システムによって提供されている。そして、各情報処理サービスによって得られる結果は、外部システム毎に異なる。また、外部システムでは、情報処理サービスを担うプログラムのアルゴリズムを、利用者に通知することなく変更することがある。このため、同じ外部システムの同じ情報処理サービスを利用した場合にも、タイミングによって結果が異なる状況がみられる。そこで、複数の外部システムの中から最適な情報処理サービスを選択することができれば、保守管理作業の効率が高まると考えられる。 Similar information processing services are often provided by multiple external systems. The results obtained by each information processing service differ for each external system. Further, in the external system, the algorithm of the program responsible for the information processing service may be changed without notifying the user. Therefore, even when the same information processing service of the same external system is used, the result may differ depending on the timing. Therefore, if the optimum information processing service can be selected from a plurality of external systems, it is considered that the efficiency of maintenance management work will be improved.
　下記特許文献１には、ネットワークに接続された複数のＯＣＲサーバの中から、評価値、処理速度等の条件に適合するＯＣＲサーバを選択し、文書画像を送信することが記載されている。 Patent Document 1 below describes that an OCR server that meets conditions such as evaluation value and processing speed is selected from a plurality of OCR servers connected to a network, and a document image is transmitted.

The beacon input unit 52 is constructed. These are constructed by controlling the hardware of the mobile terminal 20 with software such as an OS (operating system) and an application (application program).
　カメラ３２は、データ取得手段の例であり、保守員３００の操作の下、処理対象データである画像データを取得する。マイク３４も、データ取得手段の例であり、保守員３００の操作の下、処理対象データである音声データを取得する。 The camera 32 is an example of data acquisition means, and acquires image data which is the data to be processed under the operation of the maintenance staff 300. The microphone 34 is also an example of the data acquisition means, and acquires voice data which is the data to be processed under the operation of the maintenance staff 300.
　属性情報入力部４０は、属性取得手段の例であり、ビル設備または保守管理作業にかかる属性を示す属性データを取得するものである。ビル設備にかかる属性とは、ビル設備の種類、ビル設備のメーカ名、ビル設備の形式、ビル設備の設置場所など、ビル設備の特徴を表す情報をいう。ビル設備の種類とは、空調、電気、照明など別をいう。ビル設備のメーカ名とは、ビル設備の製造または販売を行う企業名をいう。ビル設備の形式とは、典型的には、メーカが仕様の相違する設備毎に付与する識別情報をいう。 The attribute information input unit 40 is an example of the attribute acquisition means, and acquires attribute data indicating attributes related to building equipment or maintenance management work. The attribute related to the building equipment refers to information indicating the characteristics of the building equipment such as the type of the building equipment, the manufacturer name of the building equipment, the type of the building equipment, and the installation location of the building equipment. The types of building equipment are different, such as air conditioning, electricity, and lighting. The manufacturer name of building equipment means the name of a company that manufactures or sells building equipment. The type of building equipment typically refers to the identification information given by the manufacturer to each equipment with different specifications.
　また、保守管理作業にかかる属性とは、保守管理作業の種別、保守管理作業の実施場所、保守管理作業を行う保守員名、保守管理作業の実施時刻など、保守管理作業の特徴を表す情報をいう。ここで、保守点検作業の種別には、空調、電気、照明などのビル設備にかかる種別、及び、点検、修理、交換などの作業形態の種別が含まれる。保守管理作業の実施場所は、屋外、屋内などの大分類、屋上、地下、廊下、階段、トイレ、室内、〇階などの中分類、〇階〇号室、〇階テナント〇内などの小分類などによって表することができる。 In addition, the attributes related to maintenance management work include information that represents the characteristics of maintenance management work, such as the type of maintenance management work, the location where maintenance management work is performed, the name of the maintenance staff who performs maintenance management work, and the time when maintenance management work is performed. say. Here, the types of maintenance and inspection work include types related to building equipment such as air conditioning, electricity, and lighting, and types of work forms such as inspection, repair, and replacement. The places where maintenance work is carried out are major classifications such as outdoor and indoor, middle classification such as rooftop, basement, corridor, stairs, toilet, indoor, 〇 floor, 〇 floor 〇 room, 〇 floor tenant 〇 inside, etc. Can be represented by.
　属性情報入力部４０は、例えば、保守員３００によるタッチパネル２８の操作を受け付けて属性データを取得するように構築される。あるいは、保守員３００によって操作される携帯端末２０のアプリが、アプリの画面状態、ＧＮＳＳ（Global Navigation Satellite System）の位置情報のなどに基づいて、属性を推測して、自動設定することも考えられる。もちろん、自動設定の結果は、保守員３００が変更できるものであってもよい。また、別の形態としては、ビル設備に設けられたＲＦＩＤ（Radio Frequency IDentifier）などを読み取り、そこに含まれる情報の中から、属性データを取得することが考えられる。 The attribute information input unit 40 is constructed so as to accept an operation of the touch panel 28 by the maintenance staff 300 and acquire attribute data, for example. Alternatively, it is conceivable that the application of the mobile terminal 20 operated by the maintenance staff 300 estimates the attributes based on the screen state of the application, the position information of GNSS (Global Navigation Satellite System), and the like, and automatically sets the attributes. .. Of course, the result of the automatic setting may be something that can be changed by the maintenance worker 300. As another form, it is conceivable to read RFID (Radio Frequency IDentifier) provided in the building equipment and acquire attribute data from the information contained therein.
　統合ＡＰＩ呼出部４２は、サービス要求手段の例であり、支援サーバ６０に対して、情報処理サービスの実行を要求する。要求は、カメラ３２からの画像データまたはマイク３４からの音声データ、及び、属性情報入力部４０からの属性データを送信して行う。また、統合ＡＰＩ呼出部４２は、結果取得手段の例でもあり、支援サーバ６０から情報処理サービスの実行結果を受信する。 The integrated API calling unit 42 is an example of a service requesting means, and requests the support server 60 to execute an information processing service. The request is made by transmitting image data from the camera 32, audio data from the microphone 34, and attribute data from the attribute information input unit 40. The integrated API calling unit 42 is also an example of the result acquisition means, and receives the execution result of the information processing service from the support server 60.
　ビーコン受信部４４は、ビーコン受信手段の例であり、ビル設備から発信される無線信号であるビーコンを受信する。ビーコンには、通常、設備の種別など、ビル設備にかかる属性の情報が含まれる。ビーコン受信部４４には、属性取得部４６と、属性正しさ判定部４８が設けられている。属性取得部４６は、属性取得手段の例であり、ビーコンを解析して、ビル設備にかかる属性データを取得する。また、属性正しさ判定部４８は、判定手段の例であり、統合ＡＰＩ呼出部４２が支援サーバ６０から情報処理サービスの実行結果を受信した場合において、実行結果の中に属性データが含まれるときに、ビーコンから得た属性データと比較を行う。比較の結果、両者が異なる不整合が見いだされた場合には、表示部５０などにその旨を表示するとともに、保守員３００に修正する機会を与える。 The beacon receiving unit 44 is an example of a beacon receiving means, and receives a beacon which is a radio signal transmitted from a building facility. Beacons usually contain information about attributes of building equipment, such as equipment type. The beacon receiving unit 44 is provided with an attribute acquisition unit 46 and an attribute correctness determination unit 48. The attribute acquisition unit 46 is an example of the attribute acquisition means, analyzes the beacon, and acquires the attribute data related to the building equipment. Further, the attribute correctness determination unit 48 is an example of the determination means, and when the integrated API calling unit 42 receives the execution result of the information processing service from the support server 60, the attribute data is included in the execution result. In addition, the attribute data obtained from the beacon is compared. If, as a result of the comparison, different inconsistencies are found between the two, a display unit 50 or the like is displayed to that effect, and the maintenance worker 300 is given an opportunity to correct the inconsistency.
　表示部５０は、タッチパネル２８を利用して形成されており、操作のための表示、情報処理サービスの実行結果の表示など、各種の表示を行う。なお、保守員３００は、表示部５０に表示された情報処理サービスの表示結果が正しくない場合に、修正のための入力を行うことができる。 The display unit 50 is formed by using the touch panel 28, and performs various displays such as a display for operation and a display of an execution result of an information processing service. The maintenance worker 300 can input for correction when the display result of the information processing service displayed on the display unit 50 is incorrect.
　実行結果正しさ入力部５２は、表示部５０に表示された結果が正しいか否かを、保守員３００が入力するために設けられている。入力された結果は、外部システムＡ１３０、外部システムＢ１４０、外部システムＣ１５０等による情報処理サービスの実行結果を評価するために利用することもできる。 The execution result correctness input unit 52 is provided for the maintenance staff 300 to input whether or not the result displayed on the display unit 50 is correct.

　支援サーバ６０は、支援サーバ６０のハードウエアを、ＯＳ、アプリなどのソフトウエアで制御することにより、図５に示す機能が構築されている。図５に示すように、支援サーバ６０は、統合ＡＰＩ管理部８０、個別ＡＰＩ呼出部８２、ＡＰＩ選択部９０、選択ルール保持部９４、選択ルール設定・更新部９６、及び、結果判定・蓄積部９８を備える。 The support server 60 has the functions shown in FIG. 5 constructed by controlling the hardware of the support server 60 with software such as an OS and an application. As shown in FIG. 5, the support server 60 includes an integrated API management unit 80, an individual API calling unit 82, an API selection unit 90, a selection rule holding unit 94, a selection rule setting / updating unit 96, and a result determination / storage unit. 98 is provided.
　統合ＡＰＩ管理部８０は、取得手段の例であり、携帯端末２０の統合ＡＰＩ呼出部４２から、画像データ、音声データなどの処理対象データと、属性データを取得するとともに、処理対象データに対する情報処理サービスの要求を受ける。この場合、統合ＡＰＩ管理部８０は、利用したいサービスの種別と、属性データをＡＰＩ選択部９０に送信し、どの外部システムを選択するかを問い合わせ、ＡＰＩ選択部９０から応答を受信する。そして、統合ＡＰＩ管理部８０は、個別ＡＰＩ呼出部８２に対し、選択された外部システムの情報処理サービスを利用するように指示を出すとともに、処理対象データを送信する。また、統合ＡＰＩ管理部８０は、送信手段の例でもあり、携帯端末２０に対して、情報処理サービスの実行結果を送信する。 The integrated API management unit 80 is an example of acquisition means, and acquires processing target data such as image data and voice data and attribute data from the integrated API calling unit 42 of the mobile terminal 20, and also processes information on the processing target data. Receive a request for service. In this case, the integrated API management unit 80 transmits the type of service to be used and the attribute data to the API selection unit 90, inquires which external system to select, and receives a response from the API selection unit 90. Then, the integrated API management unit 80 instructs the individual API calling unit 82 to use the information processing service of the selected external system, and transmits the processing target data. The integrated API management unit 80 is also an example of the transmission means, and transmits the execution result of the information processing service to the mobile terminal 20.
　個別ＡＰＩ呼出部８２は、要求手段の例であり、統合ＡＰＩ管理部８０からの指示に従って、外部システムに情報処理サービスの実行を要求する。個別ＡＰＩ呼出部８２には、外部システムＡ呼出部８４が設けられている。外部システムＡ呼出部８４は、外部システムＡ１３０が提供するＡＰＩを呼び出し、処理対象データと情報処理サービスの要求に必要となるデータとを送信して、情報処理サービスを実行させ、実行結果を取得する。同様にして、個別ＡＰＩ呼出部８２には、外部システムＢ１４０のＡＰＩを呼び出す外部システムＢ呼出部８６、及び、外部システムＣ１５０のＡＰＩを呼び出す外部システムＣ呼出部８８が設けられている。利用可能な外部システムがさらに存在する場合には、個別ＡＰＩ呼出部８２に対し、その外部システムについてのＡＰＩ呼出部の構築が行われる。 The individual API calling unit 82 is an example of the requesting means, and requests the external system to execute the information processing service according to the instruction from the integrated API management unit 80. The individual API calling unit 82 is provided with an external system A calling unit 84. The external system A calling unit 84 calls the API provided by the external system A130, transmits the processing target data and the data required for the request of the information processing service, executes the information processing service, and acquires the execution result. .. Similarly, the individual API calling unit 82 is provided with an external system B calling unit 86 that calls the API of the external system B140 and an external system C calling unit 88 that calls the API of the external system C150. If there are more available external systems, the individual API caller 82 is constructed with an API caller for that external system.
　ＡＰＩ選択部９０は、選択手段の例であり、どの外部システムの情報処理サービスを利用するかについての選択を行う。ＡＰＩ選択部９０には、属性識別部９２が設けられている。属性識別部９２は、属性データから、属性の情報を識別する。そして、選択ルール保持部９４が保持する選択ルールを参照して、その属性の下で利用すべき外部システムを選択する。 The API selection unit 90 is an example of selection means, and selects which external system's information processing service is to be used. The API selection unit 90 is provided with an attribute identification unit 92. The attribute identification unit 92 identifies the attribute information from the attribute data. Then, the external system to be used is selected under the attribute with reference to the selection rule held by the selection rule holding unit 94.
　選択ルール保持部９４は、外部システムを選択するルールである選択ルールを保持している。選択ルールは、利用したい情報処理サービス毎、かつ、適当な属性毎に定められている。 The selection rule holding unit 94 holds a selection rule that is a rule for selecting an external system. The selection rule is defined for each information processing service to be used and for each appropriate attribute.
　選択ルール設定・更新部９６は、更新手段の例であり、選択ルールの初期設定とその後の更新を行う。選択ルール設定・更新部９６は、情報処理サービス毎に、適当な属性の下で、利用可能な全ての外部システムを実際に利用し、その結果を評価させることで、その情報処理サービス及びその属性についての選択ルールの更新を行う。具体的には、選択ルール設定・更新部９６は、個別ＡＰＩ呼出部８２に対し、設定されている全ての外部システムについて情報処理サービスの要求を行わせ、得られた実行結果を結果判定・蓄積部９８に評価させることで、選択ルールの更新を行う。 The selection rule setting / update unit 96 is an example of the update means, and performs the initial setting of the selection rule and the subsequent update. The selection rule setting / updating unit 96 actually uses all available external systems under appropriate attributes for each information processing service, and evaluates the results of the information processing service and its attributes. Update the selection rule for. Specifically, the selection rule setting / updating unit 96 causes the individual API calling unit 82 to request an information processing service for all the set external systems, and determines / stores the obtained execution results. The selection rule is updated by having the unit 98 evaluate.
　結果判定・蓄積部９８は、決定手段及び更新手段の例であり、個別ＡＰＩ呼出部８２から、情報処理サービスの実行結果を取得して、評価を行う。結果判定・蓄積部９８には、評価を行うための構成として、確からしさ判定部１００、多数決判定部１０２及び精度判定部１０４を備えている。 The result determination / storage unit 98 is an example of the determination means and the update means, and the execution result of the information processing service is acquired from the individual API calling unit 82 and evaluated. The result determination / accumulation unit 98 includes a certainty determination unit 100, a majority decision determination unit 102, and an accuracy determination unit 104 as a configuration for performing evaluation.
　確からしさ判定部１００は、外部システムが情報処理サービスを行った場合に、実行結果とともに出力する確からしさのデータを利用して、実行結果の比較を行う。ここで、確からしさは、情報処理サービスの実行結果の精度等を示す情報として外部システムから提供される情報である。確からしさは、例えば、０を最低点とし１００を満点として表現される。ただし、確からしさの算出アルゴリズムは、一般に外部システムによって異なる。そこで、異なる外部システムの確からしさを比較できるように、必要に応じて調整が行われる。調整は、例えば、管理者が理論的見地から変換式を設定して行うことができる。また、調整は、例えば、実際に保守員３００が実行結果の正誤を評価した結果に基づいて、変換式を設定して行うこともできる。確からしさ判定部１００による判定結果は、通常の保守管理作業の支援において、統合ＡＰＩ管理部８０が携帯端末２０に送信する実行結果を決定するために利用される。また、確からしさ判定部１００による判定結果は、選択ルール設定・更新部９６における選択ルールの更新の情報としても利用可能である。 The certainty determination unit 100 compares the execution results by using the certainty data output together with the execution result when the external system performs the information processing service. Here, the certainty is information provided from an external system as information indicating the accuracy of the execution result of the information processing service. The certainty is expressed, for example, with 0 as the lowest score and 100 as the perfect score. However, the algorithm for calculating the certainty generally differs depending on the external system. Therefore, adjustments are made as necessary so that the certainty of different external systems can be compared. The adjustment can be performed, for example, by the administrator setting a conversion formula from a theoretical point of view. Further, for example, the adjustment can be performed by setting a conversion formula based on the result of the maintenance staff 300 actually evaluating the correctness of the execution result. The determination result by the certainty determination unit 100 is used to determine the execution result transmitted by the integrated API management unit 80 to the mobile terminal 20 in the support of the normal maintenance management work. Further, the determination result by the certainty determination unit 100 can also be used as information for updating the selection rule in the selection rule setting / update unit 96.
　多数決判定部１０２は、３つ以上の外部システムの情報処理サービスを利用した場合に、多数決方式によって妥当性が高い実行結果を決定する。すなわち、多くの外部システムの情報処理サービスが同じ実行結果を得た場合に、その実行結果は妥当性が高いと判断する。多数決の結果、票が割れたときは（すなわち１位が複数存在したときは）、例えば、確からしさ判定部１００の判定結果に委ねるなど、他の方式によって判断すればよい。多数決判定部１０２による判定結果は、通常の保守管理作業の支援において、統合ＡＰＩ管理部８０が携帯端末２０に送信する実行結果を決定するために利用される。また、多数決判定部１０２による判定結果は、選択ルール設定・更新部９６における選択ルールの更新の情報としても利用可能である。 The majority decision unit 102 determines a highly valid execution result by the majority decision method when the information processing services of three or more external systems are used. That is, when the information processing services of many external systems obtain the same execution result, it is judged that the execution result is highly valid. When the vote is broken as a result of the majority vote (that is, when there are a plurality of first places), it may be determined by another method, for example, it is left to the determination result of the certainty determination unit 100. The determination result by the majority decision determination unit 102 is used to determine the execution result transmitted by the integrated API management unit 80 to the mobile terminal 20 in the support of the normal maintenance management work. Further, the determination result by the majority decision determination unit 102 can also be used as information for updating the selection rule in the selection rule setting / update unit 96.
　精度判定部１０４は、実際に保守員３００が実行結果の正誤を評価し、その結果に基づいて、正しい実行結果を決定するものである。精度判定部１０４による判定は、例えば、選択ルール設定・更新部９６における選択ルールの更新の情報として利用される。 The accuracy determination unit 104 actually evaluates the correctness of the execution result by the maintenance staff 300, and determines the correct execution result based on the result. The determination by the accuracy determination unit 104 is used, for example, as information for updating the selection rule in the selection rule setting / update unit 96.

Information including the product name "OOOO", the model name "ABC-DEFGH", the serial number "12JKLMN", and the manufacturer name "X Co., Ltd." is described on the name plate 312. The product name is the name of the building equipment. For example, when the building equipment is an outdoor unit of an air conditioner system, a name such as "air conditioner outdoor unit" or a name registered as a trademark is given. The model name is a character string that uniquely identifies a product having the same specifications in each product of the manufacturer. In the example of FIG. 8, it is assumed that "ABC" in the model name is a character string indicating that the unit is an air conditioner outdoor unit, and "DEFGH" is a character string indicating a specific specification in the air conditioner outdoor unit. ..

The display 160 includes a photographed name plate 312. The application treats the image data as the processing target data to be the target of the OCR processing, and informs the integrated API calling unit 42 that the OCR processing request has been made (S12).
　統合ＡＰＩ呼出部４２では、ＯＣＲ処理を実施するために、属性情報の入力を求める。図９に示した例では、「属性の入力」の記載の下に、属性の入力欄１６２が設けられている。入力欄１６２には三角ボタン１６４が設けられており、三角ボタン１６４を押した場合には、入力の候補が表示される。図９に示した例では、属性として「Ｘ社　空調（屋外）」が入力されている（Ｓ１４）。なお、上述の通り、属性の入力は、例えば、ビーコンを受信して行うようにしてもよい。 The integrated API calling unit 42 requests input of attribute information in order to perform OCR processing. In the example shown in FIG. 9, an attribute input field 162 is provided under the description of "attribute input". The input field 162 is provided with a triangular button 164, and when the triangular button 164 is pressed, input candidates are displayed. In the example shown in FIG. 9, "Company X air conditioning (outdoor)" is input as an attribute (S14). As described above, the attribute may be input by receiving, for example, a beacon.
　図９の示した例では、さらに「支援サーバに送信しますか」との記載の下に、送信ボタン１６６と戻るボタン１６８が表示されている。保守員３００が送信ボタン１６６を押した場合には、統合ＡＰＩ呼出部４２は、画像データと属性データを添付して、支援サーバ６０にＯＣＲ処理要求を要求する（Ｓ１６）。 In the example shown in FIG. 9, the send button 166 and the back button 168 are further displayed under the description "Do you want to send to the support server?". When the maintenance worker 300 presses the transmission button 166, the integrated API calling unit 42 attaches image data and attribute data and requests the support server 60 for an OCR processing request (S16).
　支援サーバ６０では、統合ＡＰＩ管理部８０が、ＯＣＲ処理要求と、画像データ及び属性データを取得する。この場合、統合ＡＰＩ管理部８０は、ＡＰＩ選択部９０に対して属性データを送信し、利用する外部システム及び対応するＡＰＩを選択するよう要求する（Ｓ１８）。ＡＰＩ選択部９０では、属性識別部９２が属性データから必要な属性を識別する。そして、ＡＰＩ選択部９０は、選択ルール保持部９４が保持する選択ルールを参照して、識別した属性について、ＯＣＲ処理の要求を行うべき外部システムを選択する（Ｓ２０）。選択した外部システムの情報は、ＡＰＩ選択部９０から統合ＡＰＩ管理部８０に送信される（Ｓ２２）。 In the support server 60, the integrated API management unit 80 acquires the OCR processing request, image data, and attribute data. In this case, the integrated API management unit 80 transmits attribute data to the API selection unit 90 and requests that the external system to be used and the corresponding API be selected (S18). In the API selection unit 90, the attribute identification unit 92 identifies a necessary attribute from the attribute data. Then, the API selection unit 90 refers to the selection rule held by the selection rule holding unit 94, and selects an external system for which an OCR processing request should be made for the identified attribute (S20). Information on the selected external system is transmitted from the API selection unit 90 to the integrated API management unit 80 (S22).
　図１０は、選択ルール保持部９４が保持する選択ルールの例を示す図である。選択ルールは、情報処理サービスの種類毎に設定されている。図１０には、ＯＣＲサービスについての選択ルールが示されている。図１０の例では、選択ルールには、属性として、設備のメーカ、設備の種類、設備の場所が設定されている。設備のメーカには、Ｘ社（株式会社Ｘ）と他社（それ以外の企業）が設定されている。設備の種類としては、電気、空調などが設定されている。また、設備の場所としては、屋内と屋外が設定されている。図９に示した例では、属性として「Ｘ社　空調（屋外）」が入力されており、太枠１７０で囲まれた列の属性と一致している。 FIG. 10 is a diagram showing an example of a selection rule held by the selection rule holding unit 94. The selection rule is set for each type of information processing service. FIG. 10 shows a selection rule for the OCR service. In the example of FIG. 10, in the selection rule, the manufacturer of the equipment, the type of the equipment, and the location of the equipment are set as attributes. Company X (X Co., Ltd.) and other companies (other companies) are set as equipment manufacturers. Electricity, air conditioning, etc. are set as the types of equipment. In addition, indoors and outdoors are set as the locations of the equipment. In the example shown in FIG. 9, "Company X air conditioning (outdoor)" is input as an attribute, which matches the attribute of the column surrounded by the thick frame 170.
　設備のメーカとして、Ｘ社と他社とにわけたのは、Ｘ社の銘板の文字が、他社の銘板の文字とは異なって、特徴的であることを想定しているためである。Ｘ社についてのＯＣＲ処理と、他社についてのＯＣＲ処理では、確からしさの傾向に違いがみられることから、このように分類している。 As a manufacturer of equipment, we divided it into company X and other companies because it is assumed that the letters on the nameplate of company X are different from the letters on the nameplates of other companies. Since there is a difference in the tendency of certainty between the OCR processing for company X and the OCR processing for other companies, they are classified in this way.
　同様に、設備の種類として、電気、空調などを設けているのは、電気設備あるいは空調設備における銘板にそれぞれ特徴があり、ＯＣＲ処理において、確からしさの傾向に違いがみられるためである。また、屋内と屋外とでも、銘板の劣化の度合い、及び、光の具合が異なるため、属性の値を区別している。 Similarly, the reason why electricity, air conditioning, etc. are provided as the types of equipment is that each name plate in the electrical equipment or air conditioning equipment has its own characteristics, and there is a difference in the tendency of certainty in OCR processing. Further, since the degree of deterioration of the nameplate and the condition of light are different between indoors and outdoors, the attribute values are distinguished.
　選択ルールには、さらに、外部システムの欄が設けられており、外部システムＡ１３０、外部システムＢ１４０、外部システムＣ１５０をはじめとする複数の外部システムが設定されている。太枠１７０内に着目すると、外部システムＡ１３０については、「依頼する　９６％」との値が入力されている。これは、この属性の条件下では、外部システムＡ１３０のＯＣＲサービスの確からしさは９６％程度であり、（ここでは９５％より高ければ依頼することを想定しているため）ＯＣＲサービスを依頼するように設定されていることを示している。外部システムＢ１４０については、「依頼しない　９３％」の値が入力されている。外部システムＢ１４０では、この属性の条件下では、確からしさが９３％程度と低い値であるため、ＯＣＲサービスを依頼しないように設定されている。また、外部システムＣ１５０については、「依頼する　９７％」の値が設定されている。すなわち、外部システムＣ１５０では、確からしさが９７％程度と高いため、ＯＣＲサービスを依頼する設定がなされている。選択ルールには、同様にして、他の属性の条件においても、各外部システムに依頼するか否かの値が設定されている。 The selection rule is further provided with a column for an external system, and a plurality of external systems such as an external system A130, an external system B140, and an external system C150 are set. Focusing on the inside of the thick frame 170, the value of "request 96%" is input for the external system A130. This is because, under the condition of this attribute, the certainty of the OCR service of the external system A130 is about 96%, and it is assumed that the OCR service is requested if it is higher than 95% (here, it is assumed that the request is made). Indicates that it is set to. For the external system B140, the value of "Do not request 93%" is input. In the external system B140, under the condition of this attribute, the certainty is as low as about 93%, so that the OCR service is not requested. For the external system C150, the value of "request 97%" is set. That is, in the external system C150, the certainty is as high as about 97%, so that the OCR service is requested. Similarly, in the selection rule, the value of whether or not to request each external system is set in the condition of other attributes.
　図１０に示した選択ルールを参照した場合、ＡＰＩ選択部９０から統合ＡＰＩ管理部８０へは、外部システムＡ１３０と外部システムＣ１５０（及び図示を省略した他の外部システム）を選択する旨の応答が行われる。そして、 When referring to the selection rule shown in FIG. 10, the API selection unit 90 responds to the integrated API management unit 80 to select the external system A130 and the external system C150 (and other external systems (not shown)). Will be done. and,
　統合ＡＰＩ管理部８０は、個別ＡＰＩ呼出部８２に対し、選択された各外部システムのＡＰＩを呼び出し、ＯＣＲ処理を要求するように指示する（Ｓ２４）。指示にあたっては、統合ＡＰＩ管理部８０から個別ＡＰＩ呼出部８２には、処理対象となる画像データも送られる。 The integrated API management unit 80 instructs the individual API calling unit 82 to call the API of each selected external system and request OCR processing (S24). Upon giving an instruction, the integrated API management unit 80 also sends the image data to be processed to the individual API calling unit 82.
　個別ＡＰＩ呼出部８２では、選択された各外部システムのＡＰＩを呼び出して、ＯＣＲ処理を要求する（Ｓ２６）。ＯＣＲ処理要求にあたっては、画像データと、各ＡＰＩが要求する特別なデータ（これをＡＰＩパラメータと呼ぶことにする）が送信される。ＡＰＩパラメータには、例えば、外部システムへの登録ユーザ名、実行結果を格納する電子ファイルの種類など、各ＡＰＩに固有のデータが格納される。 The individual API calling unit 82 calls the API of each selected external system and requests OCR processing (S26). In the OCR processing request, image data and special data requested by each API (this is referred to as an API parameter) are transmitted. In the API parameter, data unique to each API such as a registered user name in an external system and a type of an electronic file for storing an execution result are stored.
　外部システムＡ１３０と外部システムＣ１５０では、それぞれＡＰＩに入力された情報を参照して、画像データに対するＯＣＲ処理を行う。このＯＣＲ処理では、実行結果である文字コードと、実行結果の確からしさのデータが出力される。外部システムＡ１３０と外部システム１５０は、それぞれ、実行結果及び確からしさのデータを、所定の電子ファイルに格納し、ＡＰＩを通じて支援サーバ６０に送る（Ｓ２８）。 The external system A130 and the external system C150 each refer to the information input to the API and perform OCR processing on the image data. In this OCR process, the character code which is the execution result and the data of the certainty of the execution result are output. The external system A130 and the external system 150 each store the execution result and the certainty data in a predetermined electronic file and send the data to the support server 60 through the API (S28).
　支援サーバ６０では、個別ＡＰＩ呼出部８２が、各ＡＰＩによる実行結果と確からしさのデータを受け取る。そして、個別ＡＰＩ呼出部８２は、各実行結果と確からしさのデータを、結果判定・蓄積部９８に送信して、どの実行結果を採用するかの判定要求を行う（Ｓ３０）。 In the support server 60, the individual API calling unit 82 receives the execution result by each API and the data of the certainty. Then, the individual API calling unit 82 transmits data of each execution result and certainty to the result determination / storage unit 98, and makes a determination request as to which execution result is to be adopted (S30).
　結果判定・蓄積部９８では、確からしさに基づく判定を、確からしさ判定部１００において行う。図１１には、実行結果とともに得られた確からしさの例を示した。図示した例では、外部システムＡ１３０の確からしさは９７％であり、外部システムＣ１５０の確からしさは９６％である。したがって、外部システムＡ１３０のＯＣＲサービスの確からしさが最も高いと判定され、ＯＣＲサービスの実行結果が蓄積される（Ｓ３２）。 The result determination / accumulation unit 98 makes a determination based on the certainty in the certainty determination unit 100. FIG. 11 shows an example of the certainty obtained together with the execution result. In the illustrated example, the certainty of the external system A130 is 97% and the certainty of the external system C150 is 96%. Therefore, it is determined that the probability of the OCR service of the external system A130 is the highest, and the execution result of the OCR service is accumulated (S32).
　結果判定・蓄積部９８は、統合ＡＰＩ管理部８０に、蓄積した外部システム１３０のＯＣＲの実行結果を送る（Ｓ３４）。そして、統合ＡＰＩ管理部８０は、このＯＣＲ結果を携帯端末に送信する（Ｓ３６）。 The result determination / storage unit 98 sends the stored OCR execution result of the external system 130 to the integrated API management unit 80 (S34). Then, the integrated API management unit 80 transmits this OCR result to the mobile terminal (S36).
　携帯端末２０では、統合ＡＰＩ呼出部４２が、ＯＣＲ結果を受信する。統合ＡＰＩ呼出部４２は、ＯＣＲ結果を解析して、所定の項目を表示部５０に表示する。 In the mobile terminal 20, the integrated API calling unit 42 receives the OCR result. The integrated API calling unit 42 analyzes the OCR result and displays a predetermined item on the display unit 50.
　図１２は、表示部５０のアプリの画面に、ＯＣＲの結果が表示された様子を示す図である。表示部５０には、「ＯＣＲの結果」との記載の下に、形名「ＡＢＣ－ＤＥＦＧＨ」と製造番号「１２ＪＫＬＭＮ」の結果の表示１８０が行われている。図１２に示した例では、ＯＣＲ結果の形名と製造番号は、図８に示した銘板３１２に記載された形名と製造番号に一致する。したがって、保守員３００は訂正を行う必要がない。 FIG. 12 is a diagram showing how the OCR result is displayed on the screen of the application of the display unit 50. On the display unit 50, under the description of "OCR result", the display 180 of the result of the model name "ABC-DEFGH" and the serial number "12JKLMN" is performed. In the example shown in FIG. 12, the model name and serial number of the OCR result match the model name and serial number described on the name plate 312 shown in FIG. Therefore, the maintenance worker 300 does not need to make a correction.
　通信状態に支障がない状態では、ステップＳ１６でＯＣＲ処理要求を行ってから、ステップＳ３８で実行結果が表示されるまでに要する時間はわずかであり（例えば１秒以内）、保守員３００は、自ら形名及び製造番号を入力する場合に比べて、はるかに迅速に形名及び製造番号を得ることができる。 In a state where there is no problem in the communication state, the time required from the OCR processing request in step S16 to the display of the execution result in step S38 is short (for example, within 1 second), and the maintenance worker 300 himself / herself The model name and serial number can be obtained much more quickly than when the model name and serial number are input.
　しかしながら、ＯＣＲの結果が、銘板３１２の記載と異なる状況も発生する。例えば、数字の「０」とアルファベットの「Ｏ」の誤りや、数字の「１」とアルファベットの小文字の「ｌ」の誤りはしばしば発生する。そこで、表示部５０には、「正しくない場合には訂正してください」との注意書きが表示され、画面をタッチして値を変更可能であることを伝えている。画面のタッチにより値が入力される場合には、実行結果正しさ入力部５２が動作して、実行結果を書き換える。 However, there may be situations where the OCR result is different from the description on the nameplate 312. For example, an error of the number "0" and the alphabet "O" or an error of the number "1" and the lowercase "l" of the alphabet often occurs. Therefore, a note saying "Please correct if it is not correct" is displayed on the display unit 50, and it is informed that the value can be changed by touching the screen. When the value is input by touching the screen, the execution result correctness input unit 52 operates to rewrite the execution result.
　あるいは、ビーコン受信部４４によってビーコンを受信している場合には、ＯＣＲの結果をビーコンの受信内容と比較することもできる。すなわち、属性正しさ判定部４８が両者を比較し、不整合がある場合には、表示部５０にその旨を表示する。不整合がＯＣＲによるものである場合、保守員３００は、画面をタッチして直接値を入力してもよいし、ビーコンの信号で置き換える操作をしてもよい。また、ビーコンの信号に誤りがある場合には、別途、ビーコンの信号を修正する処理を行う。 Alternatively, when the beacon is received by the beacon receiving unit 44, the OCR result can be compared with the received content of the beacon. That is, the attribute correctness determination unit 48 compares the two, and if there is an inconsistency, the display unit 50 displays that fact. When the inconsistency is due to OCR, the maintenance worker 300 may touch the screen to directly input a value, or may perform an operation of replacing with a beacon signal. If there is an error in the beacon signal, a process for correcting the beacon signal is performed separately.
　表示部５０には、さらに「支援サーバに登録しますか？」との記載がなされ、その下に登録ボタン１８２と戻るボタン１８４が表示されている。登録ボタン１８２を押した場合には、支援サーバ６０にＯＣＲの結果が確定的に登録される。図示を省略したが、携帯端末２０では、続く画面において、このビル設備の保守管理作業の結果が入力されることになる。携帯端末２０を用いた保守管理作業では、携帯端末２０のアプリが適宜、支援サーバ６０に通信を行って、作業内容を記録していく。支援サーバ６０では、この記録をもとに、業務報告書の作成、不具合の確認など、様々な業務を行うことが可能となる。 The display unit 50 further describes "Do you want to register with the support server?", And the registration button 182 and the back button 184 are displayed below it. When the registration button 182 is pressed, the OCR result is deterministically registered in the support server 60. Although not shown, in the mobile terminal 20, the result of the maintenance management work of the building equipment will be input on the subsequent screen. In the maintenance management work using the mobile terminal 20, the application of the mobile terminal 20 appropriately communicates with the support server 60 and records the work contents. Based on this record, the support server 60 can perform various tasks such as creating a business report and confirming a defect.
　なお、支援サーバ６０では、保守員３００が登録ボタン１８２を押して登録した形名及び製造番号を用いて、ＯＣＲ結果を評価することもできる。具体的には、結果判定・蓄積部９８の精度判定部１０４において、ＯＣＲの結果を評価する。この評価結果に基づいて、選択ルールを更新してもよい。 In the support server 60, the OCR result can also be evaluated using the model name and serial number registered by the maintenance staff 300 by pressing the registration button 182. Specifically, the accuracy determination unit 104 of the result determination / accumulation unit 98 evaluates the OCR result. The selection rule may be updated based on this evaluation result.
　以上の説明では、支援サーバ６０の確からしさ判定部１００において、確からしさが最も高いと判定された実行結果を携帯端末２０に送信する例について示した。この態様に代えて、多数決判定部１０２による多数決方式で、携帯端末２０に送信する実行結果を決定することも可能である。多数決方式は、通常は、３つ以上の外部システムにおいて導出の情報処理サービスを実施させた場合に採用することができる。 In the above description, an example is shown in which the certainty determination unit 100 of the support server 60 transmits the execution result determined to have the highest certainty to the mobile terminal 20. Instead of this aspect, it is also possible to determine the execution result to be transmitted to the mobile terminal 20 by the majority decision method by the majority decision determination unit 102. The majority voting method can usually be adopted when the derived information processing service is implemented in three or more external systems.
　続いて、選択ルールの更新過程について説明する。外部システムでは、ユーザに伝達して、あるいはユーザに伝達せずに、情報処理サービスのアルゴリズムの変更を行う場合がある。このため、情報処理サービスの実行結果の確からしさは変化する。そこで、支援サーバ６０では、定期的に、あるいは、アルゴリズムが変更されたタイミングで、選択ルールの更新を行う。 Next, the process of updating the selection rule will be explained. The external system may change the algorithm of the information processing service with or without communicating to the user. Therefore, the certainty of the execution result of the information processing service changes. Therefore, the support server 60 updates the selection rule periodically or at the timing when the algorithm is changed.
　選択ルールの更新が行われる場合には、選択ルール設定・更新部９６が、支援サーバ６０における処理の流れを変更する。具体的には、ＡＰＩ選択部９０において、選択ルールにより一部の外部システムを選択することに代えて、利用可能な全ての外部システムを選択する。そして、結果判定・蓄積部９８において全ての外部システムの実行結果を評価し、評価結果に基づいて、選択ルールを更新する。選択ルールの更新は、属性毎に行われる。 When the selection rule is updated, the selection rule setting / updating unit 96 changes the processing flow in the support server 60. Specifically, the API selection unit 90 selects all available external systems instead of selecting some external systems according to the selection rule. Then, the result determination / storage unit 98 evaluates the execution results of all the external systems, and updates the selection rule based on the evaluation results. The selection rule is updated for each attribute.
　なお、選択ルールの更新を、カメラ３２による１回の撮影の結果により行ったのでは、撮影時におけるミスなどに大きく影響されてしまう。そこで、複数回（例えば１０回以上あるい３０回以上）の実行結果に基づいて、選択ルールを変更する方がよいと考えられる。また、選択ルールの更新は、上述のように、確からしさ判定部１００ではなく、多数決判定部１０２または精度判定部１０４の結果に基づいて行うことも可能である。 If the selection rule is updated based on the result of one shooting by the camera 32, it will be greatly affected by mistakes during shooting. Therefore, it is considered better to change the selection rule based on the execution result of a plurality of times (for example, 10 times or more or 30 times or more). Further, as described above, the selection rule can be updated based on the result of the majority decision determination unit 102 or the accuracy determination unit 104 instead of the certainty determination unit 100.
　以上の説明においては、図１０に示した選択ルールを例に挙げて、外部システムの情報処理サービスを選択する態様を示した。しかし、選択ルールは、図１０に示した以外にも採用することができる。選択ルールは、属性の違いによって情報処理サービスの結果が異なることへの対策として設定している。そこで、あまり違いが生じない属性については、選択ルールから外せばよい。例えば、図１０に示した選択ルールにおいて、設備のメーカ、設備の種類及び設備の場所から１または２のみを残し、他の属性は選択ルールから外すことが考えられる。また、図１０に示した選択ルールには記載されていない別の属性によって大きな違いが生じる場合には、新たに選択ルールに組み込めばよい。一例としては、属性として、作業時刻の情報を含め、昼の時間帯と夜の時間帯において選択ルールを異ならせることが考えられる。昼と夜では、特に、屋外における照度が変わるため、ＯＣＲ処理の確からしさに違いがみられる。 In the above description, the mode of selecting the information processing service of the external system is shown by taking the selection rule shown in FIG. 10 as an example. However, the selection rule can be adopted in addition to those shown in FIG. The selection rule is set as a countermeasure against the difference in the result of the information processing service due to the difference in the attribute. Therefore, attributes that do not make much difference should be excluded from the selection rule. For example, in the selection rule shown in FIG. 10, it is conceivable to leave only 1 or 2 from the equipment manufacturer, equipment type, and equipment location, and exclude other attributes from the selection rule. Further, if a large difference is caused by another attribute not described in the selection rule shown in FIG. 10, it may be newly incorporated in the selection rule. As an example, it is conceivable to make the selection rule different between the daytime time zone and the nighttime time zone, including the work time information as an attribute. There is a difference in the certainty of OCR processing between day and night, especially because the illuminance outdoors changes.
　以上の説明は、ＯＣＲサービスを例に挙げて説明した。しかし、同様にして、画像認識サービス、あるいは、音声認識サービスの実行結果も、例えば、周囲の明るさ、周囲の雑音などに依存する。そこで、属性に応じて選択ルールを設定することが有効となる。 The above explanation was given by taking the OCR service as an example. However, similarly, the execution result of the image recognition service or the voice recognition service also depends on, for example, the ambient brightness and the ambient noise. Therefore, it is effective to set the selection rule according to the attribute.
