Description

機械設備診断システム、機械設備診断方法、および機械設備診断プログラムMechanical equipment diagnostic system, mechanical equipment diagnostic method, and mechanical equipment diagnostic program
　本発明は、下水処理施設や水道施設などのプラント施設に設置された機械設備の診断に用いることができる機械設備診断システム、機械設備診断方法、および機械設備診断プログラムに関する。 The present invention relates to a mechanical equipment diagnostic system, a mechanical equipment diagnostic method, and a mechanical equipment diagnostic program that can be used to diagnose mechanical equipment installed in a plant facility such as a sewage treatment facility or a water supply facility.
　プラント管理の分野において、機械設備を診断する可搬型の診断端末装置は、様々な診断項目を機械設備に応じて計測するとともに、場合によっては複数の施設を対象として使用されている。このような機械設備の診断においては、端末装置ごと、施設ごと、担当者ごと、といった、診断に係る条件の違いにより、診断時に行う物理量測定の項目および測定方法、などが異なる場合があった。 In the field of plant management, a portable diagnostic terminal device that diagnoses mechanical equipment measures various diagnostic items according to the mechanical equipment, and is sometimes used for multiple facilities. In the diagnosis of such mechanical equipment, there are cases where the physical quantity measurement items and the measurement method to be performed at the time of diagnosis are different depending on the conditions related to the diagnosis, such as for each terminal device, each facility, and each person in charge.
　このような課題に鑑み、たとえば日本国特開２００１－１５９９１６号公報（特許文献１）では、可搬型のデータ管理装置を用いた設備管理支援システムであって、データ管理装置からデータ管理装置に転送された設備点検情報に基づいて、各機械設備を巡回する順序を画面上に順次表示し、各機械設備の点検方法に係る点検情報が巡回順序に沿って表示されるシステムを開示している。 In view of such a problem, for example, Japanese Unexamined Patent Publication No. 2001-159916 (Patent Document 1) discloses a facility management support system using a portable data management device, which transfers data from the data management device to the data management device. Disclosed is a system in which the order of patrol of each mechanical equipment is sequentially displayed on the screen based on the provided equipment inspection information, and the inspection information related to the inspection method of each mechanical equipment is displayed in the patrol order.
日本国特開２００１－１５９９１６号公報Japanese Patent Laid-Open No. 2001-159916
　しかし、特許文献１のような技術では、可搬型の端末の使用者に対して各機械設備の点検方法を指示することはできるが、当該端末について測定された物理量データの演算処理条件を指定することはできなかった。 However, with the technique of Patent Document 1, although it is possible to instruct the user of the portable terminal how to inspect each mechanical equipment, the arithmetic processing condition of the physical quantity data measured for the terminal is specified. I couldn't do that.

The user connects an appropriate sensor as the sensor 12 to the tablet terminal 11 based on the displayed measurement condition 31, and installs the sensor 12 in the mechanical equipment E. For example, in the example of the data set 30a in Fig. 2, two acceleration sensors are installed in "Pump No. 1" before measuring "Pump No. 1" installed in "Sewage treatment plant A".
　センサ１２のタブレット端末１１への接続および機械設備Ｅへの設置の後、タッチパネル１１６への入力操作により、物理量の測定を開始できる。センサ１２が検出した物理量は、デジタル信号に変換されて信号入力部１１１に入力され、物理量データが得られる。このとき信号入力部１１１がデータを取り込む条件はあらかじめ検討されており、管理情報３０の一部である測定条件３１として一元管理されている。センサ１２による測定および信号入力部１１１による物理量データの取得は、選択されたデータセットに含まれる測定条件３１に従って行われる。たとえば図２のデータセット３０ａの例では、２基の加速度センサが測定した加速度（物理量の例）を、２５．６Ｈｚ周期で３０秒間取得し、これを加速度データ（物理量データの例）とする。取得した物理量データは、端末記憶部１１３に記憶される。 After the sensor 12 is connected to the tablet terminal 11 and installed in the mechanical equipment E, the physical quantity can be measured by an input operation on the touch panel 116. The physical quantity detected by the sensor 12 is converted into a digital signal and input to the signal input unit 111 to obtain physical quantity data. At this time, the condition for the signal input unit 111 to take in the data has been studied in advance and is centrally managed as the measurement condition 31 which is a part of the management information 30. The measurement by the sensor 12 and the acquisition of the physical quantity data by the signal input unit 111 are performed according to the measurement condition 31 included in the selected data set. For example, in the example of the data set 30a in FIG. 2, accelerations (examples of physical quantities) measured by two acceleration sensors are acquired at a cycle of 25.6Hz for 30 seconds, and these are used as acceleration data (examples of physical quantity data). The acquired physical quantity data is stored in the terminal storage unit 113.
　続いて、取得された物理量データに対して、演算部１１２が演算処理を行い、診断データ４１が生成される。物理量データそのものが膨大な量の情報を含む場合は、データそのものを見ても診断他使用の機械設備Ｅに不具合が生じているか否かを判断できない可能性がある。そこで、正常時と異常時の区別を可能にするように、物理量データに対して適切な演算処理を加える場合がある。かかる演算処理の条件はあらかじめ検討されており、管理情報３０の一部である演算処理条件３２として一元管理されている。演算部１１２による演算処理は、選択されたデータセットに含まれる演算処理条件３２に従って行われる。たとえば図２のデータセット３０ａの例では、取得された加速度データに対して、高速フーリエ変換処理を行ったデータを、診断データ４１とする。加速度データそのものは多数の周波数の正弦波の合成波であり、正常時と異常時の違いがわかりにくい。そこで、これを高速フーリエ変換すると、当該合成波を構成する正弦波の周波数と強度に関する情報を得ることができ、正常時には検出されない周波数ピークの存否や周波数ピークの強度を比較することにより、正常時と異常時とを区別することができる。 Subsequently, the arithmetic unit 112 performs arithmetic processing on the acquired physical quantity data, and diagnostic data 41 is generated. When the physical quantity data itself contains a huge amount of information, it may not be possible to determine whether or not a malfunction has occurred in the mechanical equipment E used for diagnosis or the like by looking at the data itself. Therefore, an appropriate arithmetic process may be added to the physical quantity data so that the normal time and the abnormal time can be distinguished. The conditions for such arithmetic processing have been studied in advance and are centrally managed as the arithmetic processing conditions 32 that are part of the management information 30. The arithmetic processing by the arithmetic unit 112 is performed according to the arithmetic processing condition 32 included in the selected data set. For example, in the example of the data set 30a in FIG. 2, the data obtained by performing the fast Fourier transform process on the acquired acceleration data is set as the diagnostic data 41. The acceleration data itself is a composite wave of sine waves of many frequencies, and it is difficult to understand the difference between normal and abnormal conditions. Therefore, by performing a fast Fourier transform on this, it is possible to obtain information about the frequency and intensity of the sine wave that composes the composite wave. By comparing the presence or absence of frequency peaks that are not detected in normal times and the intensity of frequency peaks, It can be distinguished from an abnormal time.
　なお、物理量データの種類によっては、演算処理を必要としない場合がある。たとえば図２のデータセット３０ｂの例では、「民間工場Ａ」に設置された「濾過装置」について取得された圧力データに対して演算処理を行わず、圧力データそのものを診断データ４１とする。濾過装置内の圧力は、正常時の数値範囲を想定可能である。一方、たとえば濾過装置に詰まりが生じる異常時には、想定範囲を超えた圧力が検出される。この圧力データの例のように、物理量データそのものについて正常時と異常時の区別がしやすい場合は、演算処理を行わなくてもよい。これらの場合は、物理量データがそのまま診断データ４１として扱われる。 Note that depending on the type of physical quantity data, arithmetic processing may not be required. For example, in the example of the data set 30b of FIG. 2, the arithmetic processing is not performed on the pressure data acquired for the “filtration device” installed in the “private factory A”, and the pressure data itself is used as the diagnostic data 41. The pressure in the filtration device can be assumed to be within the normal numerical range. On the other hand, for example, when the filter device is clogged, a pressure exceeding the expected range is detected. If it is easy to distinguish between the normal state and the abnormal state of the physical quantity data itself, as in the example of the pressure data, the calculation process may not be performed. In these cases, the physical quantity data is directly treated as the diagnostic data 41.
　また、演算部１１２は、診断データ４１の生成に用いられた管理情報３０のデータセット（管理情報の部分の例）を特定する情報を付加する。この構成により、サーバ装置２０に記憶された診断データを、測定および演算処理が行われた後ある程度の期間が経過したときに利用する場合であっても、当該診断データの生成に用いられた測定条件３１および演算処理条件３２を特定することができ、どのような条件下で生成された診断データであるのかを理解することができる。 Further, the arithmetic unit 112 adds information for specifying the data set (an example of the management information portion) of the management information 30 used for generating the diagnostic data 41. With this configuration, even when the diagnostic data stored in the server device 20 is used when a certain period of time has elapsed after the measurement and arithmetic processing, the measurement data used to generate the diagnostic data is used. The condition 31 and the arithmetic processing condition 32 can be specified, and the condition under which the diagnostic data is generated can be understood.
　物理量の測定および演算処理が完了すると、端末通信部１１４は、診断データ４１をサーバ装置２０に送信する。 When the physical quantity measurement and arithmetic processing are completed, the terminal communication unit 114 transmits the diagnostic data 41 to the server device 20.
〔サーバ装置２０の基本構成〕
　続いて、サーバ装置２０の構成について説明する。図１に示すように、サーバ装置２０は、管理情報３０、ならびに、診断端末装置１０から送信された診断データ４１を記憶するサーバ記憶部２１と、診断端末装置１０と通信するサーバ通信部２２と、サーバ記憶部２１およびサーバ通信部２２の動作を制御するサーバ制御部２３と、サーバ記憶部２１に記憶された管理情報３０、および診断データ４１を用いて機械設備Ｅの診断を行うサーバ演算部２４と、を有する。 [Basic Configuration of Server Device 20]
Next, the configuration of the server device 20 will be described. As shown in FIG. 1, the server device 20 includes a server storage unit 21 that stores management information 30 and diagnostic data 41 transmitted from the diagnostic terminal device 10, and a server communication unit 22 that communicates with the diagnostic terminal device 10. , A server control unit 23 that controls the operations of the server storage unit 21 and the server communication unit 22, and a server operation unit that diagnoses the mechanical equipment E using the management information 30 and the diagnostic data 41 stored in the server storage unit 21. 24 and.
　前述の通り、管理情報３０はサーバ装置２０において一元管理されている。当実施形態では、１台のサーバ装置２０に対して複数台の診断端末装置１０が通信可能に構成されているが、それぞれの診断端末装置１０は測定の実施に先立って最新の管理情報３０をサーバ装置２０から取得するように構成されているので、サーバ記憶部２１に記憶されている管理情報３０に変更を加えると、当該変更以降に全ての診断端末装置１０によって行われる全ての測定および診断に適用される。 As described above, the management information 30 is centrally managed by the server device 20. In this embodiment, a plurality of diagnostic terminal devices 10 are communicable with one server device 20, but each diagnostic terminal device 10 receives the latest management information 30 prior to the measurement. Since it is configured to acquire from the server device 20, if the management information 30 stored in the server storage unit 21 is changed, all measurement and diagnosis performed by all the diagnostic terminal devices 10 after the change. Applied to.
　サーバ演算部２４は、サーバ記憶部２１に記憶された管理情報３０、および診断データ４１を読み込み、これらの情報を用いて機械設備Ｅの診断を行う。具体的には、たとえば、診断データ４１と、当該機械設備Ｅの正常状態に係る基準データ（不図示）とを比較する比較演算処理を行い、診断データ４１が基準データから所定の基準を超えて乖離する場合は、当該機械設備Ｅが異常状態にあると診断する。ここで基準データとしては、診断対象の機械設備Ｅについての過去の診断データ４１を統計処理したもの、当該機械設備Ｅおよびこれと同機種の他の機械設備についての過去の診断データ４１を統計処理したもの、当該機械設備Ｅの機種についてあらかじめ定められた基準値、などを用いることができる。 The server computing unit 24 reads the management information 30 and the diagnostic data 41 stored in the server storage unit 21, and diagnoses the mechanical equipment E using these information. Specifically, for example, a comparison calculation process for comparing the diagnostic data 41 with reference data (not shown) relating to the normal state of the machine equipment E is performed, and the diagnostic data 41 exceeds the predetermined reference from the reference data. If there is a deviation, it is diagnosed that the mechanical equipment E is in an abnormal state. Here, as the reference data, statistically processed past diagnostic data 41 of the mechanical equipment E to be diagnosed, and statistically processed past diagnostic data 41 of the mechanical equipment E and other mechanical equipment of the same model as the mechanical equipment E. It is possible to use a standard value that is predetermined for the model of the machine equipment E.
　また、サーバ演算部２４は、サーバ記憶部２１に記憶された診断データ４１の各データを単体で用いて機械設備Ｅのそれぞれについての診断を行うほか、たとえば、同一機種の複数の機械設備Ｅに係る診断データ４１を統計処理して、当該機種に係る寿命予測を行うこともできる。なお、前述のように演算処理条件３２は「測定した物理量データをそのまま診断データとして用いる」旨を特定する場合を含むので、診断データ４１の一部または全部は取得された物理量データそのものでありうる。また、診断端末装置１０からサーバ記憶部２１に、診断データ４１とともに物理量データも送信しておき、サーバ演算部２４が診断データ４１とともに物理量データを用いて診断を行ってもよい。 Further, the server computing unit 24 uses each data of the diagnostic data 41 stored in the server storage unit 21 as a single unit to diagnose each of the mechanical equipments E, and, for example, for a plurality of mechanical equipments E of the same model. The diagnostic data 41 can be statistically processed to predict the life of the model. Note that, as described above, the arithmetic processing condition 32 includes the case of specifying that “measured physical quantity data is used as it is as diagnostic data”, so that part or all of the diagnostic data 41 may be the acquired physical quantity data itself. .. Alternatively, the physical quantity data may be transmitted from the diagnostic terminal device 10 to the server storage section 21 together with the diagnostic data 41, and the server computing section 24 may perform the diagnosis using the physical quantity data together with the diagnostic data 41.
　サーバ記憶部２１に記憶された診断データ４１の閲覧および利用や、管理情報３０の変更操作などのために必要なサーバ装置２０に対する入力操作は、診断端末装置１０を介して行うことも、サーバ装置２０専用の入出力装置（図示せず）を介して行うこともできる。ここで、管理情報３０を変更可能なアカウントを制限しておけば、特に、管理情報３０の誤った変更などを抑制できるため、好ましい。 The input operation to the server device 20 necessary for viewing and using the diagnostic data 41 stored in the server storage unit 21, changing operation of the management information 30, and the like can be performed through the diagnostic terminal device 10 or the server device. It can also be performed via an I/O device (not shown) dedicated to 20. Here, it is preferable to limit the accounts that can change the management information 30, because it is possible to suppress erroneous changes in the management information 30.
　本実施形態では、端末通信部１１４とサーバ通信部２２との間の通信は、携帯電話回線網、インターネットなどのネットワークを通じて行われる。この構成であれば、通信線を省略して診断端末装置１０を可搬型に構成しやすいので、１台の診断端末装置１０を、複数台の機械設備Ｅの診断に供しやすい。 In the present embodiment, the communication between the terminal communication unit 114 and the server communication unit 22 is performed via a network such as a mobile phone network or the Internet. With this configuration, it is easy to omit the communication line and configure the diagnostic terminal device 10 to be portable, and thus it is easy to use one diagnostic terminal device 10 for diagnosis of a plurality of mechanical facilities E.
〔その他の実施形態〕
　本発明に係る機械設備診断システム、機械設備診断方法、機械設備診断プログラムのその他の実施形態について説明する。なお、以下のそれぞれの実施形態で開示される構成は、矛盾が生じない限り、他の実施形態で開示される構成と組み合わせて適用することも可能である。 [Other Embodiments]
Other embodiments of the machine equipment diagnosis system, the machine equipment diagnosis method, and the machine equipment diagnosis program according to the present invention will be described. Note that the configurations disclosed in the respective embodiments below can be applied in combination with the configurations disclosed in the other embodiments as long as no contradiction occurs.
　上記の実施形態では、管理情報３０が、診断対象とする施設Ｐおよび機械設備Ｅの組合せごとに、測定条件３１および演算処理条件３２を特定する構成を例として説明した。しかし、そのような構成に限定されることなく、本発明に係る管理情報は、機械設備ごとに測定条件および演算処理条件を特定するように構成されてもよい。診断に必要な測定および演算処理の条件は、機械設備の種類や機種などにより異なるのであって、施設が異なっても同一の種類・機種の機械設備であれば同一の測定条件および演算処理条件を適用できる場合があるためである。この場合は、管理情報から施設に係る部分を省略可能であり、上記実施形態の構成に比べて、診断端末装置とサーバ装置との間の通信量を低減することができる。 In the above embodiment, the configuration in which the management information 30 specifies the measurement condition 31 and the arithmetic processing condition 32 for each combination of the facility P and the mechanical equipment E to be diagnosed has been described as an example. However, without being limited to such a configuration, the management information according to the present invention may be configured to specify the measurement condition and the arithmetic processing condition for each machine equipment. The measurement and calculation processing conditions required for diagnosis differ depending on the type and model of the machine equipment, so even if the facilities are different, the same measurement and calculation processing conditions can be used if the machine equipment is of the same type and model. This is because it may be applicable. In this case, the portion related to the facility can be omitted from the management information, and the amount of communication between the diagnostic terminal device and the server device can be reduced compared to the configuration of the above embodiment.
　上記の実施形態では、管理情報３０が、診断対象とする施設Ｐおよび機械設備Ｅの組合せごとに、測定条件３１および演算処理条件３２を特定する構成を例として説明した。ここで、本発明に係る機械設備診断システムを、異なる施設に設置されている同一の機械設備について異なる測定条件または演算処理条件が設定されている場合に、測定条件または演算条件に相違があることを使用者に報知するように構成してもよい。また、この場合、他方の機械設備について設定されている測定条件および演算処理条件を使用者に提示するように構成してもよい。さらに、使用者が提示された条件を選択できるように構成してもよい。 In the above embodiment, the configuration in which the management information 30 specifies the measurement condition 31 and the arithmetic processing condition 32 for each combination of the facility P and the mechanical equipment E to be diagnosed has been described as an example. Here, in the mechanical equipment diagnostic system according to the present invention, when different measurement conditions or arithmetic processing conditions are set for the same mechanical equipment installed in different facilities, there is a difference in the measurement conditions or arithmetic conditions. May be notified to the user. Further, in this case, the measurement condition and the arithmetic processing condition set for the other mechanical equipment may be presented to the user. Further, it may be configured so that the user can select the presented condition.
　なお、処理対象物の性状（たとえば、処理対象の水の濁度、不純物濃度など）は、施設ごとに異なる。そこで、各施設における処理対象物の性状に基づいて施設ごとの負荷率（重み係数）を設定し、各施設の機械設備の稼働実績データに負荷率（重み係数）を乗じた重み付け稼働実績データに基づいて各設備機器の測定条件および演算処理条件を決定してもよい。 Note that the properties of the object to be treated (for example, the turbidity of the water to be treated and the concentration of impurities) vary from facility to facility. Therefore, the load factor (weighting factor) for each facility is set based on the property of the processing target in each facility, and the operation result data of the mechanical equipment of each facility is multiplied by the load factor (weighting factor) to obtain the weighted operation result data. The measurement condition and the arithmetic processing condition of each equipment may be determined based on the above.
　たとえば、施設ごとに機械設備の累積稼働時間や累積停止回数などの複数の稼働実績データをそれぞれ正規化した値と、施設ごとに設定した負荷率（重み係数）とを定めて、任意の施設と機械設備とを組み合わせた場合に、過去の所定期間にわたる累積稼働時間と負荷率（重み係数）との積和演算値、および、累積停止回数と負荷率（重み係数）の積和演算値、の少なくとも一つを入力とし、故障発生時期および故障発生率の少なくとも一つを出力とする機械学習装置を構築し、その結果に基づいて測定条件をおよび演算処理条件を決定してもよい。また、同じ機械設備であっても、累積稼働時間が多い施設の場合や、累積稼働時間が少ないものであっても累積停止回数が多い場合などは、負荷率を高めに設定して機械設備と組合せるなど、目的に合った測定条件および演算処理条件を決定してもよい。なお、測定データのばらつきが比較的大きい機械設備があるときは、当該機械設備の測定の優先順位を高く設定してもよい。 For example, a value obtained by normalizing a plurality of operation record data such as cumulative operating time and cumulative number of times of stoppage of machinery and equipment for each facility, and a load factor (weighting factor) set for each facility are defined as an arbitrary facility. When combined with mechanical equipment, the product-sum calculated value of cumulative operating time and load factor (weighting factor) over the past predetermined period, and the product-sum calculated value of cumulative stop count and load factor (weighting factor) It is also possible to construct a machine learning device that inputs at least one and outputs at least one of the failure occurrence time and the failure occurrence rate, and determine the measurement condition and the arithmetic processing condition based on the result. In addition, even if it is the same machine equipment, if the facility has a long cumulative operating time, or if the cumulative operating time is short but there are a large number of cumulative stoppages, set the load factor to a higher value Measurement conditions and arithmetic processing conditions suitable for the purpose such as combination may be determined. In addition, when there is a mechanical equipment having a relatively large variation in measurement data, the priority of measurement of the mechanical equipment may be set high.
　上記の機械学習装置において用いられるアルゴリズムとしては、特定の組み合わせによる異常発生を予測するワン－クラス・サポート・ベクター・マシン（One-Class Support Vector Machine）、ＬＯＦ（local outlier factor）法、ＩＦ(Isolation Forest)法、ＲＣ(Robust Covariance)法などが例示される。 The algorithms used in the above machine learning devices include one-class support vector machines (One-Class Support Vector Machine), LOF (local outlier factor) method, and IF (Isolation) that predict anomalies due to specific combinations. The Forest) method, RC (Robust Covariance) method and the like are exemplified.
　上記の実施形態では、診断端末装置１０が、タブレット端末１１およびセンサ１２を別体として有する構成を例として説明した。しかし、そのような構成に限定されることなく、本発明に係る診断端末装置は、測定部、演算部、端末記憶部、および端末通信部が一体に構成されていてもよい。 In the above embodiment, the configuration in which the diagnostic terminal device 10 has the tablet terminal 11 and the sensor 12 as separate bodies has been described as an example. However, the diagnostic terminal device according to the present invention is not limited to such a configuration, and the measurement unit, the calculation unit, the terminal storage unit, and the terminal communication unit may be integrally configured.
　上記の実施形態では、診断端末装置１０がタブレット端末１１およびセンサ１２を有し、タブレット端末１１が、信号入力部１１１、演算部１１２、端末記憶部１１３、端末通信部１１４、端末制御部１１５、およびタッチパネル１１６の各部を含む構成を例として説明した。しかし、本発明に係る診断端末装置は、上記の各部の他の機能を持つ部分を有してよい。たとえば、診断端末装置は、当該診断端末装置が位置する地点の座標を特定可能な位置情報特定部を有してよい。かかる位置情報特定部は、ＧＰＳなどの公知の位置情報特定装置を用いる構成であってもよいし、使用者が位置情報を特定する情報を入力できるような構成であってもよい。 In the above embodiment, the diagnostic terminal device 10 includes the tablet terminal 11 and the sensor 12, and the tablet terminal 11 includes the signal input unit 111, the calculation unit 112, the terminal storage unit 113, the terminal communication unit 114, the terminal control unit 115, The configuration including each unit of the touch panel 116 has been described as an example. However, the diagnostic terminal device according to the present invention may have a part having other functions than the above-mentioned parts. For example, the diagnosis terminal device may include a position information specifying unit that can specify the coordinates of the point where the diagnosis terminal device is located. The position information specifying unit may be configured to use a known position information specifying device such as GPS, or may be configured to allow the user to input information for specifying the position information.
　上記の実施形態では、タブレット端末１１が、管理情報３０の全体をサーバ装置２０から取得する構成を例として説明した。しかし、そのような構成に限定されることなく、本発明に係る診断端末装置は、サーバ装置に記憶された管理情報のうち、当該診断端末装置が実際に所在する施設に係る部分のみを選択的に取得するように構成されてもよい。また、診断端末装置が位置情報特定部を有する場合は、当該位置情報特定部により特定される位置情報に基づいて当該診断端末装置が実際に所在する施設を特定し、管理情報のうち当該施設に係る部分のみを選択的に取得するようにしてもよい。さらに、位置情報に基づいて診断端末装置の現在地周辺に配置された機械設備を特定し、管理情報のうち当該機械設備に係る部分のみを選択的に取得するようにしてもよい。あるいは、管理情報の全体を取得するが、使用者が施設または機械設備を選択する際に、位置情報に基づいて特定される施設または機械設備が優先的に表示されるように構成されてもよい。 In the above embodiment, the tablet terminal 11 has described the configuration in which the entire management information 30 is acquired from the server device 20 as an example. However, without being limited to such a configuration, the diagnostic terminal device according to the present invention selectively selects only a portion related to the facility where the diagnostic terminal device is actually located, from the management information stored in the server device. May be configured to be acquired. In addition, when the diagnostic terminal device has a location information specifying unit, the facility in which the diagnostic terminal device is actually located is identified based on the location information identified by the location information identifying unit, and the facility is included in the management information. You may make it selectively acquire only the said part. Further, the mechanical equipment arranged around the current location of the diagnostic terminal device may be specified based on the position information, and only the portion related to the mechanical equipment of the management information may be selectively acquired. Alternatively, the entire management information may be acquired, but when the user selects the facility or the mechanical equipment, the facility or the mechanical equipment specified based on the position information may be preferentially displayed. ..
　その他の構成に関しても、本明細書において開示された実施形態は全ての点で例示であって、本発明の範囲はそれらによって限定されることはないと理解されるべきである。当業者であれば、本発明の趣旨を逸脱しない範囲で、適宜改変が可能であることを容易に理解できるであろう。したがって、本発明の趣旨を逸脱しない範囲で改変された別の実施形態も、当然、本発明の範囲に含まれる。 Regarding other configurations, it should be understood that the embodiments disclosed in the present specification are exemplifications in all respects, and the scope of the present invention is not limited thereby. Those skilled in the art will easily understand that appropriate modifications can be made without departing from the spirit of the present invention. Therefore, other embodiments modified without departing from the spirit of the present invention are naturally included in the scope of the present invention.
