Description

サーバ装置、及び、保守方法Server apparatus and maintenance method
　本発明は、サーバ装置に関し、特に保守される機器に接続されるサーバ装置に関する。 The present invention relates to a server device, and more particularly to a server device connected to a device to be maintained.
　ガスエンジン、エレベータ、又はプリンタといった機器を常に動作させるためには、保守業者による定期的な保守作業が必須である。保守作業にかかる費用を低減するためには、その保守業者は、保守作業の回数を減らすことによって、保守作業が行われる間隔をできる限り長くする必要がある。ただし保守作業を行う時間間隔が長すぎると、その間に機器が壊れてしまう可能性が高くなるため、保守業者は、機器を構成する部品の寿命が一定以下になったら即、保守作業を行う必要がある。 Regular maintenance work by maintenance contractors is indispensable in order to always operate equipment such as gas engines, elevators, and printers. In order to reduce the cost of maintenance work, the maintenance company needs to make the maintenance work interval as long as possible by reducing the number of maintenance work. However, if the time interval for performing maintenance work is too long, there is a high possibility that the device will break during that time, so the maintenance contractor needs to perform the maintenance work as soon as the lifetime of the parts that make up the device falls below a certain level. There is.
　寿命が来るまで機器を使い切るため、機器を構成する各部品の寿命を予測する技術を用いた以下のような技術が提案されている。 In order to use up the equipment until it reaches the end of its life, the following techniques using a technique for predicting the life of each part constituting the equipment have been proposed.
　機器を構成する部品の破損、性能低下、又は機能停止の時期を予測し、それに付随して考え得る故障事象を網羅し、リスクベースによるコスト評価によって最適な保守作業の間隔を決定する技術がある（例えば、特許文献１参照）。 There is a technology that predicts the time of component damage, performance degradation, or malfunction, covers possible failure events, and determines the optimal maintenance work interval by risk-based cost evaluation (For example, refer to Patent Document 1).
　また、機器を構成する部品の寿命又は次の保守までの時間を拡張し、又は交換する必要のある部品の数を低減する延命制御を提供する技術がある（例えば、特許文献２参照）。 Also, there is a technology that provides life extension control that extends the life of parts constituting the device or the time until the next maintenance, or reduces the number of parts that need to be replaced (for example, see Patent Document 2).

　特許文献１、及び特許文献２などに代表される部品寿命を用いた従来技術は、機器の部品を延命し、顧客が運用している機器の保守スケジュールの間隔を長くして、保守費用を低減させることによって、保守業者側の利益向上を図っていた。そのため、保守業者側には機器を保守するために最適と判断された日でも、保守作業を後日に延期したいという顧客要望があった場合、保守業者は、保守作業を遅らせざるを得なくなる。 Conventional technologies using component life represented by Patent Document 1 and Patent Document 2 extend the life of equipment parts, extend the maintenance schedule interval of equipment operated by customers, and reduce maintenance costs. By doing so, the profit of the maintenance company side was improved. Therefore, even if the maintenance company has a customer's request to postpone the maintenance work at a later date even on the day when it is determined that the apparatus is optimally maintained, the maintenance company is forced to delay the maintenance work.
　例えば、顧客のうち、終日機器を運転させる必要がある顧客は、保守作業を休日まで遅らせたいため、平日における保守を要望する場合がある。しかし、顧客への要望に応え、保守作業を遅らせた場合、寿命が短くなった部品が壊れ、機器の運転が停止し、顧客に損失を与える可能性が高くなる問題が生じる。 For example, among customers, a customer who needs to operate the equipment all day may request maintenance on weekdays in order to delay the maintenance work until a holiday. However, when the maintenance work is delayed in response to a request from the customer, there is a problem that a part whose life has been shortened is broken, the operation of the device is stopped, and there is a high possibility of causing a loss to the customer.
　本明細書において開示される発明の代表的な一形態を示せば以下の通りである。すなわち、顧客が用いる機器に含まれる部品から、物理量を取得する部品コントローラに接続されるサーバ装置であって、前記サーバ装置は、前記機器を停止可能な保守日について、前記顧客による入力を受け付け、前記部品コントローラによって取得された前記部品における物理量を受信し、前記受信した物理量に基づいて、前記部品の寿命を予測し、前記予測された寿命が、所定の時間より短いか否かを判定し、前記予測された寿命が、所定の時間より短いと判定された場合、前記寿命が所定の時間より短いと判定された部品を保守する日を、前記受け付けた保守日から選択し、前記所定の時間より短いと判定された寿命が、前記選択された保守日までの時間より短いか否かを判定し、前記所定の時間より短いと判定された寿命が、前記選択された保守日までの時間より短いと判定された場合、前記選択された保守日までの時間より寿命が短いと判定された部品の前記寿命を延命する方法を取得する。 A typical embodiment of the invention disclosed in this specification is as follows. That is, a server device connected to a component controller that obtains a physical quantity from a component included in a device used by a customer, wherein the server device accepts input by the customer for a maintenance date when the device can be stopped, Receiving a physical quantity in the part acquired by the parts controller, predicting a life of the part based on the received physical quantity, and determining whether the predicted life is shorter than a predetermined time; When it is determined that the predicted life is shorter than a predetermined time, a date on which a part for which the life is determined to be shorter than the predetermined time is maintained is selected from the received maintenance date, and the predetermined time is selected. It is determined whether the life determined to be shorter is shorter than the time until the selected maintenance date, and the life determined to be shorter than the predetermined time is If it is determined that shorter than the time until-option by maintenance date, to obtain a method of prolonging the life of the part life than the time until the selected maintenance date is determined to be short.
　本発明の一実施形態によると、機器を保守するにあたり顧客の要望に沿った保守日を取得し、また、取得された保守日まで機器を延命する方法を取得できる。 According to an embodiment of the present invention, it is possible to acquire a maintenance date according to a customer's request when maintaining the device, and to acquire a method for extending the life of the device until the acquired maintenance date.

In addition, a communication port such as a LAN port for transmitting the result of the life extension process of the device described later to the maintenance company is provided.
　ＣＰＵ３１００は、本実施形態のプログラムを実行するための装置である。すなわちＣＰＵ３１００は、データ入力プログラム４１００、部品寿命予測プログラム４２００、延命シーケンス検索プログラム４３００、保守可能日検索プログラム４４００、保守日決定プログラム４５００、及び部品寿命延命シーケンス実行プログラム４６００を実行するための演算装置である。 CPU 3100 is a device for executing the program of the present embodiment. That is, the CPU 3100 is an arithmetic unit for executing the data input program 4100, the component life prediction program 4200, the life extension sequence search program 4300, the maintainable date search program 4400, the maintenance date determination program 4500, and the component life extension sequence execution program 4600. is there.
　ＲＡＭ４０００は、データ入力プログラム４１００、部品寿命予測プログラム４２００、延命シーケンス検索プログラム４３００、保守可能日検索プログラム４４００、保守日決定プログラム４５００、及び、部品寿命延命シーケンス実行プログラム４６００などのプログラムを保持する。また、これらのプログラムの出力結果を一時的に保持する。 The RAM 4000 holds programs such as a data input program 4100, a component life prediction program 4200, a life extension sequence search program 4300, a serviceable day search program 4400, a maintenance date determination program 4500, and a component life extension sequence execution program 4600.

This is executed by the CPU 3100 every time the customer inputs data.
　部品寿命予測プログラム４２００は、部品６１００の状態を示す物理量を、部品６１００（１～Ｎ）に接続される部品コントローラ５１００（１～Ｎ）から取得することによって、部品６１００（１～Ｎ）の寿命を部品６１００ごとに予測するプログラムである。部品６１００の状態を示す物理量には、例えば、表面温度、又は、回転数などがある。 The component life prediction program 4200 obtains the physical quantity indicating the state of the component 6100 from the component controller 5100 (1 to N) connected to the component 6100 (1 to N), and thereby the lifetime of the component 6100 (1 to N). Is a program for predicting each part 6100. The physical quantity indicating the state of the component 6100 includes, for example, the surface temperature or the rotational speed.
　なお、部品６１００の種類に従った寿命を予測する方法には、様々な方法が提案されている。例えば、回転中に発生する摩擦によってタービンは消耗するが、摩擦によって発生する鉄くずの量、又は、回転の際の抵抗値に基づいて、タービンの寿命を予測する方法がある（例えば、特開平１０－２９３０４９号公報参照）。また、運転中の機器の表面温度などから、損傷を評価し、寿命を予測する方法がある（例えば、特開２００１－３２７２４号公報参照）。 Various methods have been proposed for predicting the lifetime according to the type of the part 6100. For example, although the turbine is consumed due to friction generated during rotation, there is a method of predicting the life of the turbine based on the amount of iron scrap generated by friction or the resistance value during rotation (for example, Japanese Patent Laid-Open 10-293049). In addition, there is a method for evaluating damage based on the surface temperature of a device during operation and the like and predicting the lifetime (see, for example, JP-A-2001-32724).
　延命シーケンス検索プログラム４３００は、部品種類ＩＤ２２６２と延命時間２２６５とに基づいて部品寿命情報データベース２２００を検索することによって、部品６１００の寿命を延命するために最適な方法を検索するプログラムである。 The life extension sequence search program 4300 is a program for searching for an optimum method for extending the life of the part 6100 by searching the part life information database 2200 based on the part type ID 2262 and the life extension time 2265.
　保守可能日検索プログラム４４００は、保守可能日データベース２１００を検索することによって、指定された日時が顧客にとって保守可能な日であるか否かを取得する。 The maintenance date search program 4400 searches the maintenance date database 2100 to obtain whether the specified date is a date that can be maintained by the customer.
　保守日決定プログラム４５００は、保守可能日検索プログラム４４００に検索をするよう指示し、保守可能日検索プログラム４４００によって取得された検索結果に基づいて、保守日を決定し、決定した保守日をディスプレイ７０００に表示するプログラムである。 The maintenance date determination program 4500 instructs the maintenance date search program 4400 to search, determines a maintenance date based on the search result acquired by the maintenance date search program 4400, and displays the determined maintenance date on the display 7000. It is a program to be displayed.
　部品寿命延命シーケンス実行プログラム４６００は、延命シーケンス検索プログラム４３００によって取得された延命手段を解釈し、部品コントローラ５１００（１～Ｎ）に、延命のための制御指示を出力するプログラムである。延命のための制御指示とは、例えば、延命する部品６１００が電子部品である場合、部品６１００の出力電圧を下げさせたり、部品６１００がポンプである場合、圧力をさげさせたりなどを指示することである。このような制御指示を部品６１００に送ることによって、部品６１００にかかる負荷を下げ、部品６１００の出力を抑えることによって、部品６１００の寿命を延ばすことができる。 The component life extension sequence execution program 4600 is a program that interprets the life extension means acquired by the life extension sequence search program 4300 and outputs a control instruction for extending the life to the component controller 5100 (1 to N). The control instruction for extending the life is, for example, instructing to lower the output voltage of the component 6100 when the component 6100 to extend the life is an electronic component, or to reduce the pressure when the component 6100 is a pump. It is. By sending such a control instruction to the component 6100, the load on the component 6100 can be reduced, and the output of the component 6100 can be suppressed, thereby extending the life of the component 6100.
　部品６１００（１～Ｎ）は、保守対象の機器に備わる部品であり、例えば、ポンプ、モーター、又は回路などの部品である。 The parts 6100 (1 to N) are parts provided in the maintenance target device, for example, parts such as a pump, a motor, or a circuit.
　部品コントローラ５１００（１～Ｎ）は、部品６１００（１～Ｎ）の各々の状態を示す状態パラメータ（部品が電子部品である場合、電流値、ポンプである場合、圧力値など）を測定する。また、測定された結果を、サーバ３０００に保持されるプログラムに送信したり、逆にサーバ３０００に保持されるプログラムに従って、部品６１００（１～Ｎ）を制御したりする装置である。 The part controller 5100 (1 to N) measures state parameters (state of current value when the part is an electronic part, pressure value when the part is a pump, etc.) indicating the state of the part 6100 (1 to N). Further, the apparatus is a device that transmits the measured result to a program held in the server 3000, or conversely controls the component 6100 (1 to N) according to the program held in the server 3000.
　各部品コントローラ５１００（１～Ｎ）は、部品６１００（１～Ｎ）のうち各々が制御する部品６１００（１～Ｎ）の部品ＩＤを、部品コントローラ５１００（１～Ｎ）に備わるＲＯＭなどの記憶媒体に保持する。そして、サーバ３０００に保持されるプログラムに部品６１００（１～Ｎ）において測定された状態パラメータを送信する場合、部品コントローラ５１００（１～Ｎ）は、どの部品６１００（１～Ｎ）においてどの状態パラメータが測定されたかを示すため、部品ＩＤと状態パラメータとを組にして送信する。 Each component controller 5100 (1 to N) stores a component ID of a component 6100 (1 to N) controlled by each component 6100 (1 to N), such as a ROM provided in the component controller 5100 (1 to N). Hold on the medium. When the state parameter measured in the part 6100 (1 to N) is transmitted to the program held in the server 3000, the part controller 5100 (1 to N) determines which state parameter in which part 6100 (1 to N). In order to indicate whether or not is measured, a part ID and a state parameter are transmitted as a set.
　サーバ３０００に保持されるプログラムに従って、部品６１００（１～Ｎ）が制御される場合、サーバ３０００が部品コントローラ５１００に、部品ＩＤと制御命令を組にした指示を送ることによって、部品ＩＤに対応した部品６１００（１～Ｎ）は、制御信号に従って制御される。 When the part 6100 (1 to N) is controlled according to the program held in the server 3000, the server 3000 sends an instruction in which the part ID and the control command are paired to the part controller 5100, thereby corresponding to the part ID. The parts 6100 (1 to N) are controlled according to the control signal.
　保守会社サーバ６５００は、サーバ３０００から送られる後述の延命処理の結果を、保守会社が受信するためのサーバである。 The maintenance company server 6500 is a server for the maintenance company to receive the result of the life extension process described later sent from the server 3000.
　保守会社側ディスプレイ６８００は、保守会社サーバ６５００がサーバ３０００から受信した結果である、顧客が運用する機器の延命処理結果を表示するための表示装置である。例えば、液晶パネル、又は、プリンタでもよい。 The maintenance company-side display 6800 is a display device for displaying a life extension processing result of a device operated by a customer, which is a result received from the server 3000 by the maintenance company server 6500. For example, a liquid crystal panel or a printer may be used.
　ディスプレイ７０００は、機器を運用する顧客に対して、データの入力画面や保守日を表示するための表示装置である。例えば、液晶パネル、又は、プリンタでもよい。 The display 7000 is a display device for displaying a data input screen and a maintenance date to a customer who operates the device. For example, a liquid crystal panel or a printer may be used.
　以下では図１に示すＲＡＭ４０００に保持されるプログラムによる部品６１００の延命処理及び保守日決定の処理を図５～図８のフローチャートを用いて説明する。 Hereinafter, the life extension processing of the component 6100 and the maintenance date determination processing by the program held in the RAM 4000 shown in FIG. 1 will be described with reference to the flowcharts of FIGS.
　図５は、本発明の実施形態の全体の処理を示すフローチャートである。 FIG. 5 is a flowchart showing the overall processing of the embodiment of the present invention.
　図５において、Ｓ４１００は顧客が機器導入時に初期入力として一度だけ行う保守可能な日を入力するサブルーチンである。Ｓ４１００の詳細なフローをサブルーチンＳＵＢ０１として図６に示す。 In FIG. 5, S4100 is a subroutine for inputting a maintenance day that is performed once by the customer as an initial input when the device is installed. A detailed flow of S4100 is shown as a subroutine SUB01 in FIG.
　図６は、本発明の実施形態の保守可能日の初期入力処理を示すフローチャートである。図６に示すＳＵＢ０１は、図５に示すＳ４１００（ＳＵＢ０１）に相当する。 FIG. 6 is a flowchart showing the initial input process of the maintenance possible date according to the embodiment of the present invention. SUB01 shown in FIG. 6 corresponds to S4100 (SUB01) shown in FIG.
　データ入力プログラム４１００は、保守可能日、すなわち、顧客の都合上機器の運用を止めて保守作業を行ってもよい日を顧客によって入力させるために、後述する入力画面をディスプレイ７０００に表示する（Ｓ４１０５）。 The data input program 4100 displays an input screen, which will be described later, on the display 7000 in order to allow the customer to input a maintenance possible date, that is, a date on which the maintenance operation can be performed for the customer's convenience (S4105). ).
　次に顧客は、保守可能日入力装置１０００を用いて保守可能日を入力する（Ｓ４１１０）。 Next, the customer inputs a maintenance date using the maintenance date input device 1000 (S4110).
　次にデータ入力プログラム４１００は、顧客によって入力された保守可能日のデータとして、日時とその日時が保守可能か否かを示す値とを受信する（Ｓ４１１５）。 Next, the data input program 4100 receives the date and time and the value indicating whether or not the date / time can be maintained as the maintenance date data input by the customer (S4115).
　次にデータ入力プログラム４１００は、Ｓ４１０５において入力された保守可能日のデータに基づいて、保守不可能な日時の範囲が延命可能な最大時間を越えているか否かを判定する（Ｓ４１１７）。 Next, the data input program 4100 determines whether or not the maintenance possible date / time range exceeds the maximum time that can be extended based on the maintenance available date data input in S4105 (S4117).
　保守不可能な日時の範囲が延命可能な最大時間を越える場合、データ入力プログラム４１００は、後述するエラー画面７２００を表示した後、保守可能日を顧客に再入力を促すため、Ｓ４１０５に戻る。保守不可能な日時の範囲が延命可能な最大時間以下である場合、Ｓ４１２０に進む。 When the range of the date and time when maintenance is impossible exceeds the maximum time that can extend the life, the data input program 4100 displays an error screen 7200 to be described later, and then returns to S4105 to prompt the customer to re-enter the maintenance date. When the range of date and time that cannot be maintained is equal to or shorter than the maximum time that can be extended, the process proceeds to S4120.
　ここで、延命可能な最大時間とは、図４に示す部品寿命延命シーケンステーブル２２６０の延命時間カラム２２６５に格納される日数の最大値であり、機器の設計時に決定される定数である。このため延命可能な最大時間は、あらかじめＲＡＭ４０００におけるプログラムのデータとして格納される。 Here, the maximum time that can be extended is the maximum value of the number of days stored in the life extension column 2265 of the component life extension sequence table 2260 shown in FIG. 4, and is a constant determined when the device is designed. Therefore, the maximum time that can be extended is stored as program data in the RAM 4000 in advance.
　以上でＳＵＢ０１は終了し、図５のＳ４２００に移行する。 SUB01 is complete | finished above and transfers to S4200 of FIG.
　Ｓ４２００とＳ４２５０において、部品寿命予測プログラム４２００は、部品６１００（１～Ｎ）の各寿命を予測する。まず部品寿命予測プログラム４２００は、部品コントローラ５１００（１～Ｎ）に部品ＩＤとその部品６１００の状態パラメータとの組を要求し、部品コントローラ５１００（１～Ｎ）から送られた部品６１００の状態パラメータとの組を受信する（Ｓ４２００）。 In S4200 and S4250, the component life prediction program 4200 predicts each life of the component 6100 (1 to N). First, the component life prediction program 4200 requests the component controller 5100 (1 to N) for a set of the component ID and the state parameter of the component 6100, and the state parameter of the component 6100 sent from the component controller 5100 (1 to N). (S4200).
　そして、部品寿命予測プログラム４２００は、受信した状態パラメータと、プログラムに組み込まれた部品６１００の寿命予測モデルを用いて、各６１００の部品寿命ｔを予測する（Ｓ４２５０）。部品６１００（１～Ｎ）の寿命が全て予測できたらＳ４３００に移行する。 Then, the part life prediction program 4200 predicts the part life t of each 6100 using the received state parameter and the life prediction model of the part 6100 incorporated in the program (S4250). When all the lifetimes of the parts 6100 (1 to N) have been predicted, the process proceeds to S4300.
　なお、Ｓ４２００及びＳ４２５０は、一定時間を置いて定期的に行われてもよい。 Note that S4200 and S4250 may be performed periodically after a certain period of time.
　また、ここで寿命予測モデルとは前述した通り、部品６１００における抵抗値又は表面温度などから寿命を予測するモデルであり、あらかじめＲＡＭ４０００に格納される。 Also, the life prediction model here is a model for predicting the life from the resistance value or surface temperature of the component 6100 as described above, and is stored in the RAM 4000 in advance.
　次にサーバ３０００は、Ｓ４２５０において予測された各部品寿命ｔのうち限界寿命を下回った部品寿命ｔがあるか否かを判定する（Ｓ４３００）。限界寿命を下回った部品寿命ｔが一つも無い場合はＳ４２００に戻る。 Next, the server 3000 determines whether or not there is a component life t that is less than the limit life among the component lifetimes t predicted in S4250 (S4300). If there is no part life t less than the limit life, the process returns to S4200.
　Ｓ４３００において、限界寿命を下回った部品寿命ｔが一つでもある場合、処理は、Ｓ４３５０に移行する。そして、その限界寿命を下回った部品寿命ｔに対応する部品６１００の部品ＩＤをＲＡＭ４０００に格納し（Ｓ４３５０）、Ｓ４４００に移行する。 In S4300, when there is even one component life t that is less than the limit life, the process proceeds to S4350. Then, the part ID of the part 6100 corresponding to the part life t less than the limit life is stored in the RAM 4000 (S4350), and the process proceeds to S4400.
　限界寿命の値は、これ以上寿命が短くなった場合、部品６１００が故障して動かなくなる確率が非常に高くなる寿命の値であり、前述の寿命予測モデルと、故障して動かなくなる確率をどこまで許容するかという保守会社の運用方針とによって定まる定数である。 The limit life value is a life value at which the probability that the part 6100 will fail and become inoperable when the life becomes shorter than this is the life value. This is a constant determined by the maintenance company's operation policy of whether to allow.
　限界寿命を下回った部品６１００を交換する保守日を決定するため、保守可能日検索プログラム４４００は、現在に最も近い日時で、保守可能な日時を見つけてそれが現時点から何日後かを取得する（Ｓ４４００）。Ｓ４４００の詳細なフローをサブルーチンＳＵＢ０２として図７に示す。 In order to determine the maintenance date for replacing the part 6100 whose service life is less than the limit life, the serviceable date search program 4400 finds the serviceable date / time at the date / time closest to the current time, and obtains the number of days from the current time ( S4400). A detailed flow of S4400 is shown in FIG. 7 as a subroutine SUB02.
　図７は、本発明の実施形態の保守可能日を検索する処理を示すフローチャートである。図７に示すＳＵＢ０２は、図５に示すＳ４４００に相当する。 FIG. 7 is a flowchart showing a process for searching for a maintenance possible date according to the embodiment of the present invention. SUB02 shown in FIG. 7 corresponds to S4400 shown in FIG.
　保守可能日検索プログラム４４００は、サーバ３０００のＯＳなどの機能を用いて、現在時刻を取得する（Ｓ４４１０）。 The maintenance day search program 4400 obtains the current time using a function such as the OS of the server 3000 (S4410).
　次に保守可能日検索プログラム４４００は、Ｓ４４１０において取得した現在時刻によって、保守日可能日テーブル２１１０を検索し、現在時刻が保守可能であるか否かを判定する（Ｓ４４１５）。例えば、現在時刻が２０１０／０１／０１／００：００である場合、保守可能日検索プログラム４４００は、保守可能日テーブル２１１０の保守可／不可カラム２１１６の値から保守が不可と判定できる。 Next, the maintenance date search program 4400 searches the maintenance date availability table 2110 based on the current time acquired in S4410, and determines whether or not the current time is maintainable (S4415). For example, when the current time is 2010/01/01/00: 00, the maintenance date search program 4400 can determine that maintenance is not possible from the value in the maintenance availability / inhibition column 2116 of the maintenance availability date table 2110.
　Ｓ４４１５において現在時刻が保守可能であると判定された場合、保守可能日検索プログラム４４００は、現在時刻をＲＡＭ４０００に格納し（Ｓ４１１７）、ＳＵＢ０２を終了する。また、Ｓ４４１５において保守不可能であると判定された場合、Ｓ４４２０に移行する。 If it is determined in S4415 that the current time is maintainable, the maintenance-possible date search program 4400 stores the current time in the RAM 4000 (S4117), and ends SUB02. If it is determined in S4415 that maintenance is not possible, the process moves to S4420.
　Ｓ４４２０とＳ４４２５とにおいて、保守可能日検索プログラム４４００は、現在時刻から最も近く、かつ、保守可能な日を検索する。 In S4420 and S4425, the maintenance day search program 4400 searches for a maintenance day that is closest to the current time and that can be maintained.
　次に保守可能日検索プログラム４４００は、保守可能日テーブル２１１０において以前に検索した日時より、一つ先の日時カラム２１１３の情報を検索する（Ｓ４４２０）。例えば、Ｓ４４１５において検索された日時カラム２１１３が２０１０／０１／０１／００：００であり、Ｓ４４１５からＳ４４２０に処理が移行した場合、Ｓ４４２０において、以前に検索された日時カラム２１１３は、Ｓ４４１５で検索された現在時刻２０１０／０１／０１／００：００である。このため、保守可能日検索プログラム４４００は、Ｓ４４１５において検索された日時カラム２１１３を上から１段下がった日時カラム２１１３を検索し、２０１０／０１／０２／００：００の値を取得する。 Next, the maintenance date search program 4400 searches the date and time column 2113 ahead of the date and time previously searched in the maintenance date table 2110 (S4420). For example, if the date / time column 2113 searched in S4415 is 2010/01/01/00: 00: 00 and the process proceeds from S4415 to S4420, the date / time column 2113 searched previously in S4420 is searched in S4415. The current time is 2010/01/01/00: 00. Therefore, the maintainable date search program 4400 searches the date / time column 2113 that is one step down from the date / time column 2113 searched in S4415, and obtains the value 2010/01/02/00: 00.
　次に保守可能日検索プログラム４４００は、Ｓ４４２０において取得した日時が保守可能か否かを判定する（Ｓ４４２５）。そして、保守可能である場合、Ｓ４４２７に移行し、保守不可能である場合、Ｓ４２２０に戻る。 Next, the maintenance date search program 4400 determines whether or not the date and time acquired in S4420 can be maintained (S4425). If maintenance is possible, the process proceeds to S4427. If maintenance is not possible, the process returns to S4220.
　以上のＳ４４２０及びＳ４４２５のループによって、例えば、Ｓ４４１５において検索された現在時刻が２０１０／０１／０１／００：００だとすると、図２に示す保守可能日テーブル２１１０において、最も近い保守可能な日時として２０１０／０１／０４／００：００が取得される。 For example, if the current time searched in S4415 is 2010/01/01/00: 00: 00 by the loop of S4420 and S4425 described above, 2010/01 is set as the closest maintainable date / time in the maintainable date table 2110 shown in FIG. 01/04/00: 00 is acquired.
　次に保守可能日検索プログラム４４００は、Ｓ４４２０及びＳ４４２５のループによって取得された最も近い保守可能な日時をＲＡＭ４０００に格納する（Ｓ４２２７）。 Next, the maintenance date search program 4400 stores the closest maintenance date and time acquired by the loop of S4420 and S4425 in the RAM 4000 (S4227).
　さらに保守可能日検索プログラム４４００は、Ｓ４４１５において取得された現在時刻から、最も近い保守可能な日までの時間Ｔを算出する。そのために現在時刻からＳ４２２７において取得された最も近い保守可能な日までの時間Ｔを算出し、算出された時間ＴをＲＡＭ４０００に格納する（Ｓ４４３０）。 Further, the maintenance day search program 4400 calculates a time T from the current time acquired in S4415 to the nearest maintenance day. Therefore, a time T from the current time to the nearest maintainable date acquired in S4227 is calculated, and the calculated time T is stored in the RAM 4000 (S4430).
　その後、ＳＵＢ０２は終了し、図５のＳ４５００に処理が移行する。 Thereafter, SUB02 ends, and the process proceeds to S4500 in FIG.
　次にサーバ３０００は、Ｓ４３００において取得された部品６１００の寿命が尽きるまでに保守作業が可能か否かを判定する（Ｓ４５００）。サーバ３０００は、Ｓ４５００において、現在時刻における残りの部品寿命ｔと、Ｓ４４００において取得された現在時刻から最も近い保守可能な日までの時間の長さＴを比較する。 Next, the server 3000 determines whether or not maintenance work can be performed before the lifetime of the component 6100 acquired in S4300 expires (S4500). In S4500, the server 3000 compares the remaining component life t at the current time with the length T of time from the current time acquired in S4400 to the nearest serviceable day.
　ｔ＜Ｔである場合、部品６１００の寿命が尽きるまでに保守作業ができないため、サーバ３０００は、部品６１００に延命処理が必要と判定し、Ｓ４６００に移行する。ｔ≧Ｔである場合、部品６１００の寿命が尽きるまでに保守作業ができるため、サーバ３０００は、部品６１００に延命処理は不要であると判定し、延命処理をスキップしてＳ４８００に移行する。 When t <T, since the maintenance work cannot be performed before the lifetime of the part 6100 is exhausted, the server 3000 determines that a life extension process is necessary for the part 6100, and proceeds to S4600. When t ≧ T, maintenance work can be performed before the life of the part 6100 is exhausted, so the server 3000 determines that the life extension process is unnecessary for the part 6100, skips the life extension process, and proceeds to S4800.
　次に延命シーケンス検索プログラム４３００は、Ｓ４５００において延命処理が必要と判定された部品６１００に、最適な延命手段を検索する（Ｓ４６００）。Ｓ４６００の詳細なフローをサブルーチンＳＵＢ０３として図８に示す。 Next, the life extension sequence search program 4300 searches for the optimum life extension means for the part 6100 determined to require the life extension processing in S4500 (S4600). A detailed flow of S4600 is shown in FIG. 8 as a subroutine SUB03.
　図８は、本発明の実施形態の延命シーケンスを検索する処理を示すフローチャートである。 FIG. 8 is a flowchart showing processing for searching for a life extension sequence according to the embodiment of the present invention.
　延命シーケンス検索プログラム４３００は、図５に示すＳ４３５０においてＲＡＭ４０００に格納された、限界寿命を下回った部品６１００の部品ＩＤを読み出す（Ｓ４６２０）。そして、延命シーケンス検索プログラム４３００は、その部品ＩＤを検索キーとして図３に示す部品種類ＩＤテーブル２２３０を検索する。部品種類ＩＤテーブル２２３０の部品ＩＤカラム２２３３を検索条件にして検索し、検索結果の部品種類ＩＤカラム２２３６の値を取得する（Ｓ４６４０）。 The life extension sequence search program 4300 reads the part ID of the part 6100 that has been stored in the RAM 4000 in S4350 shown in FIG. Then, the life extension sequence search program 4300 searches the component type ID table 2230 shown in FIG. 3 using the component ID as a search key. A search is performed using the component ID column 2233 of the component type ID table 2230 as a search condition, and the value of the component type ID column 2236 of the search result is acquired (S4640).
　次に延命シーケンス検索プログラム４３００は、Ｓ４４３０においてＲＡＭ４０００に格納された保守可能日までの時間Ｔを読み出し、時間Ｔを延命時間とする（Ｓ４６５０）。 Next, the life extension sequence search program 4300 reads the time T until the maintenance possible date stored in the RAM 4000 in S4430, and sets the time T as the life extension time (S4650).
　次に延命シーケンス検索プログラム４３００は、Ｓ４６４０において取得された部品種類ＩＤカラム２２３６の値によって、部品寿命延命シーケンステーブル２２６０を検索し、２２３６の値に対応する延命時間２２６５のうち、Ｓ４６５０において取得された延命時間Ｔに対応する部品寿命延命シーケンス２２６７を取得する（Ｓ４６６０）。そして、取得された２２６７をＲＡＭ４０００に格納する。 Next, the life extension sequence search program 4300 searches the component life extension sequence table 2260 based on the value of the component type ID column 2236 acquired in S4640, and is acquired in S4650 out of the life extension time 2265 corresponding to the value of 2236. The component life extension sequence 2267 corresponding to the life extension time T is acquired (S4660). The acquired 2267 is stored in the RAM 4000.
　その後、ＳＵＢ０３は終了し、処理は図５に示すＳ４７００に移行する。 Thereafter, SUB03 ends, and the process proceeds to S4700 shown in FIG.
　サーバ３０００は、延命が必要な部品６１００（１～Ｎ）に、Ｓ４６００において取得された２２６７に示される延命シーケンスを実行する。すなわちサーバ３０００は、Ｓ４７００において、ＲＡＭ４０００に格納された２２６７を読み出す。 The server 3000 executes the life extension sequence indicated by 2267 acquired in S4600 for the parts 6100 (1 to N) that need the life extension. That is, the server 3000 reads 2267 stored in the RAM 4000 in S4700.
　そして部品寿命延命シーケンス実行プログラム４６００は、読み出された２２６７を解釈する。部品寿命延命シーケンス実行プログラム４６００は、解釈の結果に基づいて、延命が必要な部品６１００に対応する部品コントローラ５１００に、部品ＩＤと延命のための部品負荷を下げる制御を指示する。部品コントローラ５１００は、延命が必要な部品６１００に、部品の負荷を下げる制御を行う。これによって、部品６１００の寿命は、保守日まで機器を稼動するために必要な期間、延命される（Ｓ４７００）。 The component life extension sequence execution program 4600 interprets the read 2267. Based on the interpretation result, the component life extension sequence execution program 4600 instructs the component controller 5100 corresponding to the component 6100 that requires life extension to perform control for reducing the component ID and the component load for extending the life. The component controller 5100 performs control to reduce the component load on the component 6100 that requires life extension. As a result, the lifetime of the component 6100 is extended for a period necessary to operate the device until the maintenance date (S4700).
　次に保守日決定プログラム４５００は、Ｓ４４２７においてＲＡＭ４０００に格納された現在時刻に最も近い保守可能日を読み出す。そして、機器を運用する顧客側のディスプレイ７０００に、図１０に示す７３００のように保守可能日を表示する（Ｓ４８００）。 Next, the maintenance date determination program 4500 reads the maintenance possible date closest to the current time stored in the RAM 4000 in S4427. Then, the maintenance possible date is displayed on the display 7000 on the customer side that operates the device as shown by 7300 in FIG. 10 (S4800).
　次に保守日決定プログラム４５００は、サーバ３０００の通信機能を用いて、保守会社に保守可能日と、延命シーケンスを行った部品６１００の情報を送信する。サーバ３０００から送信された情報は保守会社サーバ６５００によって受信され、保守会社側ディスプレイ６８００に表示される（Ｓ４８５０）。 Next, the maintenance date determination program 4500 uses the communication function of the server 3000 to transmit the maintenance possible date and information of the part 6100 that has performed the life extension sequence to the maintenance company. Information transmitted from the server 3000 is received by the maintenance company server 6500 and displayed on the maintenance company display 6800 (S4850).
　図９Ａは、本発明の実施形態のディスプレイ７０００に表示される保守可能日の入力画面例を示す説明図である。 FIG. 9A is an explanatory diagram illustrating an example of a maintenance day input screen displayed on the display 7000 according to the embodiment of this invention.
　図９Ａに示す入力画面７１００は、左の列に日時、中央及び右の列にその日時が保守可能か不可能かを示すチェックボックスが配置され、顧客は日時ごとに保守可能か不可能かの情報をマウスなどの保守可能日入力装置１０００によって、チェックボックスに入力する。入力画面７１００は、図６に示すＳ４１０５において表示される。 In the input screen 7100 shown in FIG. 9A, a check box indicating whether the date and time can be maintained is arranged in the left column, and whether the date and time can be maintained or not is arranged in the center and right columns. Information is input to the check box by the maintenance day input device 1000 such as a mouse. The input screen 7100 is displayed in S4105 shown in FIG.
　図９Ｂは、本発明の実施形態のディスプレイ７０００に表示されるエラー画面例を示す説明図である。 FIG. 9B is an explanatory diagram illustrating an example of an error screen displayed on the display 7000 according to the embodiment of this invention.

　図１０Ａは、本発明の実施形態のディスプレイ７０００に表示される結果画面例を示す説明図である。 FIG. 10A is an explanatory diagram illustrating a result screen example displayed on the display 7000 according to the embodiment of this invention.
　図１０Ａに示す画面例は、図５に示すＳ４８００において表示される結果画面７３００である。 The screen example shown in FIG. 10A is a result screen 7300 displayed in S4800 shown in FIG.
　図１０Ｂは、本発明の実施形態のディスプレイ７０００に表示される別の結果画面例を示す説明図である。 FIG. 10B is an explanatory diagram illustrating another example of a result screen displayed on the display 7000 according to the embodiment of this invention.
　図１０Ｂに示す画面例は、図５に示すＳ４８００において表示される別の結果画面７４００である。Ｓ４８００において表示される画面は、結果画面７４００のように、保守可能日と延命シーケンスとの情報を表示してもよい。 The screen example shown in FIG. 10B is another result screen 7400 displayed in S4800 shown in FIG. The screen displayed in S4800 may display information on the maintenance possible date and the life extension sequence as in the result screen 7400.
　従来技術は部品を延命し、顧客の機器の保守スケジュール間隔を長くして保守費用を低減するという保守業者側の利益向上が目的であった。そのため、保守業者側には最適と判断された日でも、保守作業を後日に延期したいという顧客要望があった場合に対応不可能になるという問題があった。 The purpose of the conventional technology was to improve the profits of the maintenance company by extending the life of the parts and extending the maintenance schedule interval of the customer's equipment to reduce the maintenance cost. For this reason, there is a problem that even if it is determined that the maintenance company is optimal, it becomes impossible to respond to a customer request to postpone the maintenance work at a later date.
　この課題に対し本発明において、顧客は、機器を停止し、かつ、保守作業を行っても良い保守可能日を、機器導入時に本装置に記憶させておく。本発明の装置は日々、機器を構成する部品１～Ｎの寿命を予測し続ける。 In response to this problem, in the present invention, the customer stores the maintenance available date on which the apparatus is stopped and maintenance work can be performed in the apparatus when the apparatus is introduced. The device of the present invention continues to predict the life of parts 1 to N constituting the equipment every day.
　部品の寿命が一定以下になった場合、各部品の種類、及び最も近い保守可能日までの時間に合わせた部品寿命延命シーケンスを検索し、検索された部品寿命延命シーケンスを実行する。部品寿命延命シーケンスによって、保守の要望日時まで部品が故障せずに機械が稼動し続けられる。 When the life of a part is below a certain level, the part life extension sequence is searched according to the type of each part and the time until the nearest serviceable date, and the searched part life extension sequence is executed.
