Description

産業用コンピュータ、産業用コンピュータシステム、オペレーティングシステム更新方法及びプログラムIndustrial computer, industrial computer system, operating system update method and program
　本発明は、産業用コンピュータ、産業用コンピュータシステム、オペレーティングシステム更新方法及びプログラムに関する。 The present invention relates to an industrial computer, an industrial computer system, an operating system update method, and a program.
　工場に代表される施設では、生産システム、検査システム及び加工システムに代表される種々のシステムが、プログラムを実行する処理装置によって実現されている。この種の処理装置の動作を変更するためには、通常、実行されるプログラムを変更する必要がある。そこで、複数のプログラムを切り替える技術を利用することが考えられる（例えば、特許文献１を参照）。 In a facility represented by a factory, various systems represented by a production system, an inspection system, and a processing system are realized by a processing device that executes a program. In order to change the operation of this type of processing apparatus, it is usually necessary to change the program to be executed. Therefore, it is conceivable to use a technique for switching a plurality of programs (for example, see Patent Document 1).
　特許文献１には、起動時に補助記憶装置に記憶されている複数のプログラムから特定のプログラムを主記憶装置にロードする方式でプログラムを実行する処理装置について記載されている。この処理装置は、補助記憶装置からのデータの読み出しを制御するコントローラを有し、当該コントローラは、ユーザによって設定されたスイッチの状態に応じて特定のプログラムを選択的にロードする。 Patent Document 1 describes a processing device that executes a program by loading a specific program into a main storage device from a plurality of programs stored in an auxiliary storage device at the time of activation. The processing device includes a controller that controls reading of data from the auxiliary storage device, and the controller selectively loads a specific program according to the state of the switch set by the user.
特開昭５８－１１２１１８号公報JP 58-112118 A
　しかしながら、特許文献１の技術では、処理装置のＯＳ（Operating System）を更新する必要が生じた場合に、作業者が煩雑な作業を強いられるおそれがある。この作業は、例えば、ＯＳを更新するためのプログラムを処理装置に記憶させた上で、主記憶装置にロードされるプログラムを切り替えるためにスイッチを操作する作業である。そして、処理装置が遠隔地、高所、或いは狭いスペースに設置されているときには、スイッチの直接操作に長い時間がかかってしまう。 However, in the technique of Patent Document 1, when there is a need to update the OS (Operating System) of the processing apparatus, there is a risk that the operator may be forced to perform complicated work. This operation is, for example, an operation of operating a switch to switch a program loaded in the main storage device after storing a program for updating the OS in the processing device. When the processing device is installed in a remote place, a high place, or a narrow space, it takes a long time to directly operate the switch.
　さらに、ＯＳを更新する際には処理装置が動作を停止することとなるため、処理装置が動作を停止しても差し支えない日時にＯＳを更新することが望ましい。しかしながら、一般的には、そのような日時が夜間又は休日に限られることからも、作業者の作業負担が大きくなる。また、処理装置を１台ずつ順に操作しなければならず、複数の処理装置のＯＳを更新するときには工数が多くなることからも、作業者の作業負担が大きくなる。 Furthermore, when the OS is updated, the processing device stops operating. Therefore, it is desirable to update the OS at a date and time when the processing device can stop operating. However, in general, since such date and time is limited to nighttime or holidays, the work burden on the worker increases. In addition, the processing apparatuses must be operated one by one in sequence, and man-hours increase when updating the OSs of a plurality of processing apparatuses.
　本発明は、上記の事情に鑑みてなされたものであり、ＯＳを更新する際の作業負担を軽減することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to reduce the work load when updating the OS.
　上記目的を達成するため、本発明の産業用コンピュータは、サーバに接続されオペレーティングシステムで動作する産業用コンピュータであって、第１オペレーティングシステムを記憶するオペレーティングシステム記憶手段と、第１オペレーティングシステムとは異なる第２オペレーティングシステムと、第１オペレーティングシステムを第２オペレーティングシステムに更新する更新プログラムと、をサーバから取得する取得手段と、予め規定された条件が成立すると、産業用コンピュータが起動する際に実行される起動プログラムとして更新プログラムを指定して産業用コンピュータを再起動する第１指定手段と、を備え、更新プログラムは、オペレーティングシステム記憶手段に記憶される第１オペレーティングシステムを第２オペレーティングシステムに更新する更新手段、及び、起動プログラムとして第２オペレーティングシステムを指定して産業用コンピュータを再起動する第２指定手段、として機能する。 In order to achieve the above object, an industrial computer according to the present invention is an industrial computer connected to a server and operating with an operating system. The operating system storage means for storing the first operating system and the first operating system are: Executed when the industrial computer is started when a predetermined condition is satisfied, an acquisition means for acquiring from the server a different second operating system, an update program for updating the first operating system to the second operating system And a first designation means for rebooting the industrial computer by designating the update program as a startup program to be executed, and the update program stores the first operating system stored in the operating system storage means as a second option. Updating means for updating the rating system, and functions as a second specifying means, to restart the industrial computer by specifying the second operating system as a boot program.
　本発明によれば、産業用コンピュータは、サーバから第２オペレーティングシステムと更新プログラムとを取得して、当該更新プログラムが、第１オペレーティングシステムを第２オペレーティングシステムに更新する更新手段として機能する。このため、作業者が産業用コンピュータを直接操作する必要はない。また、産業用コンピュータは、予め規定された条件が成立したときにオペレーティングシステムを更新する。このため、適当な条件を設定することで、任意のタイミングにオペレーティングシステムを更新させることができる。したがって、作業者の作業負担を軽減することができる。 According to the present invention, the industrial computer acquires the second operating system and the update program from the server, and the update program functions as update means for updating the first operating system to the second operating system. For this reason, the operator does not need to directly operate the industrial computer. The industrial computer updates the operating system when a predetermined condition is satisfied. For this reason, the operating system can be updated at an arbitrary timing by setting appropriate conditions. Therefore, the work burden on the worker can be reduced.

If this flag is ON, the program storage unit is used as an activation program executed when the OS update device 10 is activated. This indicates that 17 update programs 33 are designated. If the flag is OFF, the activation information 151 indicates that the OS of the OS storage unit 16 is designated as the activation program. In FIG. 1, a dashed arrow extending from the boot information 151 to the first OS 31 indicates that the first OS 31 is designated as the boot program. Note that the activation of the OS update device 10 includes activation when the power is turned on by a user operation and restart of the OS update device 10 itself. The startup information storage unit 15 functions as startup information storage means in the claims.
　図２には、起動情報記憶部１５に記憶される情報の構成が示されている。図２に示されるように、起動情報記憶部１５は、起動情報１５１に加えて、条件設定領域１５２を有する。条件設定領域１５２は、ＯＳを更新するための条件に関する情報が設定される記憶領域である。この条件の詳細については、後述する。 FIG. 2 shows the configuration of information stored in the activation information storage unit 15.

The OS storage unit 16 stores the first OS 31, and the second OS 32 and the update program 33 are written in the program storage unit 17. The storage capacity of the program storage unit 17 may be any size that can store the second OS 32 and the update program 33. When the storage capacity of the program storage unit 17 is larger than the data size of the second OS 32 and the update program 33, other data may be stored in the program storage unit 17. The OS storage unit 16 functions as an operating system storage unit according to the claims, and the program storage unit 17 functions as a program storage unit according to the claims.
　続いて、ＯＳ更新装置１０によって実行されるＯＳ更新処理のフローについて、図３～１１を用いて説明する。ＯＳ更新処理は、ＯＳ記憶部１６に記憶される第１ＯＳ３１を、サーバ２１から配信される第２ＯＳ３２に更新する処理であって、図３に示される手順で実行される。なお、ＯＳ更新装置１０は、ＯＳの実行中において、制御処理、演算処理及び通信処理に代表されるＯＳの更新とは異なる処理を実行するが、図３に示されるフローでは、このような処理については省略されている。 Subsequently, the flow of OS update processing executed by the OS update device 10 will be described with reference to FIGS. The OS update process is a process for updating the first OS 31 stored in the OS storage unit 16 to the second OS 32 distributed from the server 21, and is executed according to the procedure shown in FIG. The OS update device 10 executes a process different from the OS update represented by the control process, the arithmetic process, and the communication process during the execution of the OS.

　ＯＳ更新処理では、ＯＳ更新装置１０が起動する（ステップＳ１）。具体的には、ユーザがハードウェアスイッチを操作することで、ＯＳ更新装置１０の電源が投入される。 In the OS update process, the OS update device 10 is activated (step S1). Specifically, when the user operates the hardware switch, the OS update device 10 is powered on.
　次に、ＯＳ更新装置１０は、ＢＩＯＳ記憶部１４に記憶されるＢＩＯＳによりＢＩＯＳ処理を実行する（ステップＳ２）。このＢＩＯＳ処理について、図４を用いて説明する。 Next, the OS update device 10 executes a BIOS process using the BIOS stored in the BIOS storage unit 14 (step S2). This BIOS processing will be described with reference to FIG.
　ＢＩＯＳ処理では、ＢＩＯＳを実行するプロセッサ１１が、起動情報記憶部１５から起動情報１５１を読み出す（ステップＳ２１）。そして、プロセッサ１１は、起動プログラムとしてプログラム記憶部１７の更新プログラム３３が指定されているか否かを判定する（ステップＳ２２）。具体的には、プロセッサ１１は、起動情報１５１がＯＮであるかを判定する。 In the BIOS process, the processor 11 that executes the BIOS reads the activation information 151 from the activation information storage unit 15 (step S21). Then, the processor 11 determines whether or not the update program 33 in the program storage unit 17 is designated as the startup program (step S22). Specifically, the processor 11 determines whether the activation information 151 is ON.
　起動プログラムとして更新プログラム３３が指定されていないと判定した場合（ステップＳ２２；Ｎｏ）、プロセッサ１１は、ＯＳ記憶部１６のＯＳを主記憶部１２にロードする（ステップＳ２３）。図３中のステップＳ１に続くステップＳ２のＢＩＯＳ処理においては、ステップＳ２２の判定が否定され、第１ＯＳ３１がロードされる。これにより、主記憶部１２には、図５に示されるように、ＢＩＯＳによって使用されるＢＩＯＳ使用領域１２１と、第１ＯＳ３１が格納されるＯＳ格納領域１２２と、第１ＯＳ３１によって使用されるデータが格納されるＯＳデータ領域１２３と、が形成される。そして、ＯＳ更新装置１０は、第１ＯＳ３１によって提供される機能を発揮することができる状態になる。具体的には、図１に示される状態になる。その後、ＢＩＯＳ処理が終了する。 When it is determined that the update program 33 is not designated as the activation program (step S22; No), the processor 11 loads the OS of the OS storage unit 16 into the main storage unit 12 (step S23). In the BIOS process in step S2 following step S1 in FIG. 3, the determination in step S22 is negative and the first OS 31 is loaded. Thereby, as shown in FIG. 5, the main storage unit 12 stores a BIOS use area 121 used by the BIOS, an OS storage area 122 in which the first OS 31 is stored, and data used by the first OS 31. OS data area 123 is formed. Then, the OS update device 10 is in a state where the function provided by the first OS 31 can be exhibited. Specifically, the state shown in FIG. 1 is obtained. Thereafter, the BIOS process ends.
　ステップＳ２２にて起動プログラムとして更新プログラム３３が指定されていると判定した場合（ステップＳ２２；Ｙｅｓ）、プロセッサ１１は、プログラム記憶部１７の更新プログラム３３を主記憶部１２にロードする（ステップＳ２４）。これにより、主記憶部１２には、図６に示されるように、ＢＩＯＳによって使用されるＢＩＯＳ使用領域１２１と、更新プログラム３３が格納される更新プログラム格納領域１２４と、更新プログラム３３によって使用されるデータが格納される更新プログラムデータ領域１２５と、が形成される。その後、ＢＩＯＳ処理が終了する。 If it is determined in step S22 that the update program 33 is designated as the activation program (step S22; Yes), the processor 11 loads the update program 33 in the program storage unit 17 into the main storage unit 12 (step S24). . As a result, as shown in FIG. 6, the main storage unit 12 is used by the BIOS use area 121 used by the BIOS, the update program storage area 124 in which the update program 33 is stored, and the update program 33. An update program data area 125 in which data is stored is formed. Thereafter, the BIOS process ends.
　図３に戻り、ステップＳ２に続いて、ＯＳ更新装置１０は、第１ＯＳ３１による第１ＯＳ処理を実行する（ステップＳ３）。この第１ＯＳ処理について、図７を用いて説明する。 3, following step S2, the OS update device 10 executes the first OS process by the first OS 31 (step S3). The first OS process will be described with reference to FIG.
　第１ＯＳ処理では、ＯＳ更新装置１０は、第２ＯＳ３２の送信が可能であるかをサーバ２１に問い合わせる（ステップＳ３１）。具体的には、取得部１３が、配信可能な最新のＯＳのバージョンをサーバ２１に問い合わせる。 In the first OS process, the OS update device 10 inquires of the server 21 whether the second OS 32 can be transmitted (step S31). Specifically, the acquisition unit 13 inquires of the server 21 about the latest OS version that can be distributed.
　次に、ＯＳ更新装置１０は、送信が可能である旨の応答をサーバ２１から得たか否かを判定する（ステップＳ３２）。具体的には、取得部１３が、配信可能な最新のＯＳのバージョンが、第１ＯＳ３１のバージョンより新しいか否かを判定する。 Next, the OS update device 10 determines whether or not the server 21 has received a response indicating that transmission is possible (step S32). Specifically, the acquisition unit 13 determines whether or not the latest distributable OS version is newer than the first OS 31 version.
　送信可能ではないと判定した場合（ステップＳ３２；Ｎｏ）、ＯＳ更新装置１０は、ステップＳ３１以降の処理を繰り返す。これにより、サーバ２１から第２ＯＳ３２の配信が開始されるまで、ＯＳ更新装置１０が待機することとなる。 If it is determined that transmission is not possible (step S32; No), the OS update device 10 repeats the processing from step S31. As a result, the OS update device 10 waits until distribution of the second OS 32 from the server 21 is started.
　一方、送信可能であると判定した場合（ステップＳ３２；Ｙｅｓ）、ＯＳ更新装置１０は、第２ＯＳ３２及び更新プログラム３３を取得してプログラム記憶部１７に格納する（ステップＳ３３）。具体的には、取得部１３が、圧縮された状態の第２ＯＳ３２と、更新プログラム３３と、をサーバ２１から受信して、プロセッサ１１に送出することによりプログラム記憶部１７に格納する。これにより、プログラム記憶部１７は、図８に示されるように、第２ＯＳ３２の圧縮データ及び更新プログラム３３を記憶する状態となる。このように第２ＯＳ３２の圧縮データがサーバ２１から伝送されるため、圧縮されない場合に比べて伝送時間を短縮することができる。また、第２ＯＳ３２の圧縮データがプログラム記憶部１７に格納されるため、圧縮されない場合に比べてプログラム記憶部１７の記憶容量を節約することができる。 On the other hand, if it is determined that transmission is possible (step S32; Yes), the OS update device 10 acquires the second OS 32 and the update program 33 and stores them in the program storage unit 17 (step S33). Specifically, the acquisition unit 13 receives the compressed second OS 32 and the update program 33 from the server 21 and sends them to the processor 11 to store them in the program storage unit 17. As a result, the program storage unit 17 is in a state of storing the compressed data of the second OS 32 and the update program 33, as shown in FIG. Since the compressed data of the second OS 32 is transmitted from the server 21 in this way, the transmission time can be shortened compared to the case where the compressed data is not compressed. Further, since the compressed data of the second OS 32 is stored in the program storage unit 17, the storage capacity of the program storage unit 17 can be saved as compared with the case where the compressed data is not compressed.
　次に、ＯＳ更新装置１０は、ＯＳを更新するための更新条件が成立したか否かを判定する（ステップＳ３４）。具体的には、第１指定部１１１が、起動情報記憶部１５の条件設定領域１５２に格納されている情報を読み出して、設定された条件が成立しているか否かを判定する。更新条件は、ユーザによって予め規定される条件であって、例えば、ユーザによって予め指定された日時を過ぎること、ユーザによって予め指定された時間が設定時刻から経過したこと、又は、サーバ２１から特定の情報を受信したことである。ただし、更新条件は、これらに限定されず、他の条件であってもよい。 Next, the OS update device 10 determines whether an update condition for updating the OS is satisfied (step S34). Specifically, the first designation unit 111 reads information stored in the condition setting area 152 of the activation information storage unit 15 and determines whether the set condition is satisfied. The update condition is a condition defined in advance by the user. For example, the update date and time specified by the user has passed, the time specified in advance by the user has elapsed from the set time, or specified from the server 21 Information has been received. However, the update conditions are not limited to these, and may be other conditions.
　更新条件が成立していないと判定した場合（ステップＳ３４；Ｎｏ）、ＯＳ更新装置１０は、ステップＳ３４の判定を繰り返す。これにより、ＯＳ更新装置１０は、第２ＯＳ３２及び更新プログラム３３をプログラム記憶部１７に格納してＯＳを更新する準備を整えた上で、更新条件が成立するまで待機することとなる。 When it is determined that the update condition is not satisfied (step S34; No), the OS update device 10 repeats the determination of step S34. Thus, the OS update device 10 stores the second OS 32 and the update program 33 in the program storage unit 17 and prepares to update the OS, and then waits until the update condition is satisfied.
　一方、更新条件が成立していると判定した場合（ステップＳ３４；Ｙｅｓ）、ＯＳ更新装置１０は、起動プログラムとして更新プログラム３３を指定する（ステップＳ３５）。具体的には、第１指定部１１１が、プログラム記憶部１７の更新プログラム３３を示す起動情報１５１を起動情報記憶部１５に書き込むことで、起動プログラムとして更新プログラム３３を指定する。より詳細には、第１指定部１１１が、起動情報１５１のフラグをＯＮに変更する。これにより、ＯＳ更新装置１０は、図９に示される状態になる。図９では、起動情報１５１から更新プログラム３３へ延びる破線の矢印によって、更新プログラム３３が起動プログラムとして指定されていることが示されている。 On the other hand, when it is determined that the update condition is satisfied (step S34; Yes), the OS update device 10 designates the update program 33 as the activation program (step S35). Specifically, the first designation unit 111 writes the activation information 151 indicating the update program 33 of the program storage unit 17 in the activation information storage unit 15, thereby designating the update program 33 as the activation program. More specifically, the first designation unit 111 changes the flag of the activation information 151 to ON. As a result, the OS update device 10 enters the state shown in FIG. In FIG. 9, the broken line arrow extending from the activation information 151 to the update program 33 indicates that the update program 33 is designated as the activation program.
　図７に戻り、ステップＳ３５に続いて、ＯＳ更新装置１０は、ＯＳ更新装置１０自体を再起動する（ステップＳ３６）。具体的には、第１指定部１１１が、ＯＳ更新装置１０の電源が一時的に切断されてから再度投入される設定をする。これにより、ＯＳ更新装置１０の電源が一旦切断されて第１ＯＳ処理が終了する。 Returning to FIG. 7, following step S35, the OS update device 10 restarts the OS update device 10 itself (step S36). Specifically, the first designation unit 111 performs setting so that the OS update device 10 is temporarily turned off and then turned on again. As a result, the power source of the OS update device 10 is once cut off, and the first OS process ends.
　図３に戻り、ステップＳ３の第１ＯＳ処理に続いて、ＯＳ更新装置１０が再起動して（ステップＳ４）、ＢＩＯＳ処理を再度実行する（ステップＳ２）。このステップＳ４に続くステップＳ２のＢＩＯＳ処理では、図４に示される処理が実行される。ここで、図４中のステップＳ２２の判定が肯定されて（ステップＳ２２；Ｙｅｓ）、ステップＳ２４が実行される。そして、ＯＳ更新装置１０は、図９に示されるように、更新プログラム３３によって実現される機能を発揮することができる状態になる。具体的には、図９中の実線のブロックで示されるように、プロセッサ１１が、第２指定部１１２及び更新部１１３として機能する。 3, following the first OS process in step S3, the OS update device 10 is restarted (step S4), and the BIOS process is executed again (step S2). In the BIOS process in step S2 following step S4, the process shown in FIG. 4 is executed. Here, the determination in step S22 in FIG. 4 is affirmed (step S22; Yes), and step S24 is executed. Then, as shown in FIG. 9, the OS update device 10 is in a state where the function realized by the update program 33 can be exhibited. Specifically, as indicated by a solid line block in FIG. 9, the processor 11 functions as the second designation unit 112 and the update unit 113.
　ステップＳ４に続くステップＳ２のＢＩＯＳ処理が終了すると、ＯＳ更新装置１０は、更新プログラム３３による更新処理を実行する（ステップＳ５）。この更新処理について、図１０を用いて説明する。 When the BIOS process in step S2 following step S4 ends, the OS update device 10 executes an update process by the update program 33 (step S5). This update process will be described with reference to FIG.
　更新処理では、ＯＳ更新装置１０は、ＯＳ記憶部１６に記憶される第１ＯＳ３１を第２ＯＳ３２に更新する（ステップＳ５１）。具体的には、更新部１１３が、圧縮された状態でプログラム記憶部１７に格納されている第２ＯＳ３２を読み出して展開し、展開した第２ＯＳ３２をＯＳ記憶部１６に上書きすることにより、ＯＳ記憶部１６の第１ＯＳ３１を第２ＯＳ３２に書き換える。 In the update process, the OS update device 10 updates the first OS 31 stored in the OS storage unit 16 to the second OS 32 (step S51). Specifically, the update unit 113 reads out and expands the second OS 32 stored in the program storage unit 17 in a compressed state, and overwrites the OS storage unit 16 with the expanded second OS 32, whereby the OS storage unit The first OS 31 of 16 is rewritten to the second OS 32.
　次に、ＯＳ更新装置１０は、起動プログラムとして第２ＯＳ３２を指定する（ステップＳ５２）。具体的には、第２指定部１１２が、ＯＳ記憶部１６の第２ＯＳ３２を示す起動情報１５１を起動情報記憶部１５に書き込むことで、起動プログラムとして第２ＯＳ３２を指定する。より詳細には、第２指定部１１２が、起動情報１５１のフラグをＯＦＦに変更する。これにより、ＯＳ更新装置１０は、図１１に示される状態になる。図１１では、起動情報１５１から第２ＯＳ３２へ延びる破線の矢印によって、第２ＯＳ３２が起動プログラムとして指定されていることが示されている。なお、第２ＯＳ３２は、更なるＯＳの更新に備えて、第１ＯＳ３１と同様に第１指定部１１１を実現するため、図１１では、第１指定部１１１のブロックが実線で示されている。 Next, the OS update device 10 designates the second OS 32 as a startup program (step S52). Specifically, the second designation unit 112 writes the activation information 151 indicating the second OS 32 of the OS storage unit 16 in the activation information storage unit 15, thereby designating the second OS 32 as the activation program. More specifically, the second designation unit 112 changes the flag of the activation information 151 to OFF. As a result, the OS update device 10 enters the state shown in FIG. In FIG. 11, a broken line arrow extending from the activation information 151 to the second OS 32 indicates that the second OS 32 is designated as the activation program. Note that the second OS 32 implements the first designation unit 111 in the same manner as the first OS 31 in preparation for further OS updates. In FIG. 11, the block of the first designation unit 111 is indicated by a solid line.
　図１０に戻り、ステップＳ５２に続いて、ＯＳ更新装置１０は、ＯＳ更新装置１０自体を再起動する（ステップＳ５３）。具体的には、第２指定部１１２が、ＯＳ更新装置１０の電源が一時的に切断されてから再度投入される設定をする。これにより、ＯＳ更新装置１０の電源が一旦切断されて更新処理が終了する。 Returning to FIG. 10, following step S52, the OS update device 10 restarts the OS update device 10 itself (step S53). Specifically, the second designation unit 112 performs setting so that the OS update device 10 is temporarily turned off and then turned on again. Thereby, the power source of the OS update device 10 is once cut off, and the update process ends.
　図３に戻り、ステップＳ５の更新処理が終了することで、ＯＳ更新装置１０が再起動して（ステップＳ６）、ＢＩＯＳ処理を再度実行する（ステップＳ２）。ステップＳ６に続くステップＳ２のＢＩＯＳ処理では、ＯＳ記憶部１６の第２ＯＳ３２が実行される。これにより、第１ＯＳ３１から第２ＯＳ３２への更新が達成され、ＯＳ更新処理が終了する。 Returning to FIG. 3, when the update process of step S5 is completed, the OS update device 10 is restarted (step S6), and the BIOS process is executed again (step S2). In the BIOS process of step S2 following step S6, the second OS 32 of the OS storage unit 16 is executed. Thereby, the update from the first OS 31 to the second OS 32 is achieved, and the OS update process ends.
　続いて、ＯＳを更新する際に実行されるプログラムの遷移について、図１２のシーケンス図を用いて説明する。 Subsequently, the transition of the program executed when the OS is updated will be described with reference to the sequence diagram of FIG.
　図１２に示されるように、ＯＳ更新装置１０の電源をＯＮにする操作がなされると（ステップＳ７１）、ＢＩＯＳ記憶部１４に記憶されるＢＩＯＳが主記憶部１２にロードされて、ＢＩＯＳ３０によるＢＩＯＳ処理が実行される（ステップＳ２）。このステップＳ２においては、起動情報１５１はＯＦＦであるため、ＢＩＯＳ３０は、ＯＳ記憶部１６から第１ＯＳ３１を主記憶部１２にロードする（ステップＳ７２）。 As shown in FIG. 12, when an operation to turn on the OS update device 10 is performed (step S71), the BIOS stored in the BIOS storage unit 14 is loaded into the main storage unit 12, and the BIOS by the BIOS 30 is loaded. Processing is executed (step S2). In this step S2, since the activation information 151 is OFF, the BIOS 30 loads the first OS 31 from the OS storage unit 16 to the main storage unit 12 (step S72).
　次に、主記憶部１２にロードされた第１ＯＳ３１によって、第１ＯＳ処理が実行される（ステップＳ３）。この第１ＯＳ処理は、第２ＯＳ３２の取得と、更新プログラム３３の取得と、起動情報１５１の変更と、を含む。その後、ＯＳ更新装置１０が再起動する（ステップＳ７３）。 Next, the first OS process is executed by the first OS 31 loaded in the main storage unit 12 (step S3). The first OS processing includes acquisition of the second OS 32, acquisition of the update program 33, and change of the startup information 151. Thereafter, the OS update device 10 restarts (step S73).
　再起動したＯＳ更新装置１０は、ＢＩＯＳ３０によるＢＩＯＳ処理を再度実行する（ステップＳ２）。このステップＳ２では、起動情報１５１がＯＮに設定されているため、更新プログラム３３が主記憶部１２にロードされる（ステップＳ７４）。 The restarted OS update device 10 executes the BIOS process by the BIOS 30 again (step S2). In step S2, since the activation information 151 is set to ON, the update program 33 is loaded into the main storage unit 12 (step S74).
　次に、主記憶部１２にロードされた更新プログラム３３によって、更新処理が実行される（ステップＳ５）。この更新処理は、ＯＳの更新と、起動情報１５１の変更と、を含む。その後、ＯＳ更新装置１０が再起動する（ステップＳ７５）。 Next, an update process is executed by the update program 33 loaded in the main storage unit 12 (step S5). This update process includes an OS update and a change in the startup information 151. Thereafter, the OS update device 10 restarts (step S75).
　再起動したＯＳ更新装置１０は、ＢＩＯＳ３０によるＢＩＯＳ処理を再度実行する（ステップＳ２）。このステップＳ２では、起動情報１５１がＯＦＦに設定されているため、新たな第２ＯＳ３２が主記憶部１２にロードされる（ステップＳ７６）。そして、第２ＯＳ３２による第２ＯＳ処理が実行される（ステップＳ９）。これにより、ＯＳの更新が完了する。 The restarted OS update device 10 executes the BIOS process by the BIOS 30 again (step S2). In this step S2, since the activation information 151 is set to OFF, a new second OS 32 is loaded into the main storage unit 12 (step S76). Then, the second OS process by the second OS 32 is executed (step S9). Thereby, the update of the OS is completed.
　以上、説明したように、ＯＳ更新装置１０は、サーバ２１から第２ＯＳ３２と更新プログラム３３とを取得して、当該更新プログラム３３が、第１ＯＳ３１を第２ＯＳ３２に更新する更新部１１３として機能する。このため、ＯＳの更新を担当する作業者がＯＳ更新装置１０を直接操作する必要がない。また、ＯＳ更新装置１０は、予め規定された条件が成立したときにＯＳを更新した。このため、適当な条件を設定することで、任意のタイミングにＯＳを更新させることができる。したがって、作業者の作業負担を軽減することができる。また、更新プログラム３３が、起動プログラムとして第２ＯＳを指定してＯＳ更新装置１０を再起動する第２指定部１１２として機能する。これにより、ＯＳ記憶部１６のＯＳが更新されると、新たな第２ＯＳを利用することができる状態になり、更新処理に伴うユーザの作業を軽減することができる。 As described above, the OS update device 10 functions as the update unit 113 that acquires the second OS 32 and the update program 33 from the server 21 and updates the first OS 31 to the second OS 32. For this reason, it is not necessary for the operator in charge of OS update to directly operate the OS update device 10. In addition, the OS update device 10 updates the OS when a predetermined condition is satisfied. Therefore, the OS can be updated at an arbitrary timing by setting appropriate conditions. Therefore, the work burden on the worker can be reduced. Further, the update program 33 functions as the second designation unit 112 that designates the second OS as the boot program and restarts the OS update device 10. Thus, when the OS of the OS storage unit 16 is updated, a new second OS can be used, and the user's work associated with the update process can be reduced.
　また、ＯＳ更新装置１０は、起動情報記憶部１５を備え、第１指定部１１１は、更新プログラム３３を示す起動情報１５１を書き込むことで起動プログラムとして更新プログラム３３を指定し、第２指定部１１２は、第２ＯＳ３２を示す起動情報１５１を書き込むことで起動プログラムとして第２ＯＳ３２を指定した。これにより、ＯＳ更新装置１０の電源が一旦切断されて再起動したときに、適当なプログラムを実行することができる。 In addition, the OS update device 10 includes a startup information storage unit 15, and the first specification unit 111 specifies the update program 33 as a startup program by writing the startup information 151 indicating the update program 33, and the second specification unit 112. Specified the second OS 32 as a startup program by writing the startup information 151 indicating the second OS 32. Thus, when the OS update device 10 is powered off and restarted, an appropriate program can be executed.
　また、取得部１３は、第２ＯＳ３２の送信が可能かをサーバ２１に問い合わせて、送信が可能である旨の応答を得た場合に、第２ＯＳ３２をサーバ２１から取得した。これにより、遠隔のサーバ２１から第２ＯＳ３２を配信することができる。また、サーバ２１にて配信の準備が完了する時刻を調整することで、第２ＯＳ３２を配信するタイミングを調整することができる。 In addition, the acquisition unit 13 inquires of the server 21 whether the transmission of the second OS 32 is possible, and obtains the second OS 32 from the server 21 when obtaining a response indicating that the transmission is possible. Thereby, the second OS 32 can be distributed from the remote server 21. Moreover, the timing at which the second OS 32 is distributed can be adjusted by adjusting the time at which the server 21 completes preparation for distribution.
　また、取得部１３は、第２ＯＳ３２の配信が可能である旨の応答を得た場合に、第２ＯＳ３２とともに更新プログラム３３をサーバ２１から取得した。これにより、第１ＯＳ３１を第２ＯＳ３２に更新するための更新プログラム３３として、適当なプログラムを配信することができる。例えば、第２ＯＳ３２を更に第３ＯＳに更新するための更新プログラム３３を、第３ＯＳに適したものとすることができる。 In addition, when the obtaining unit 13 obtains a response indicating that the second OS 32 can be distributed, the obtaining unit 13 obtains the update program 33 together with the second OS 32 from the server 21. As a result, an appropriate program can be distributed as the update program 33 for updating the first OS 31 to the second OS 32. For example, the update program 33 for further updating the second OS 32 to the third OS can be made suitable for the third OS.
　また、ＯＳ記憶部１６とプログラム記憶部１７とは、異なる記憶装置として構成された。これにより、ＯＳ記憶部１６の記憶容量を消費することなくＯＳを更新することができる。 In addition, the OS storage unit 16 and the program storage unit 17 are configured as different storage devices. Thereby, the OS can be updated without consuming the storage capacity of the OS storage unit 16.
　また、起動プログラムは、ＢＩＯＳ３０によって選択されて実行された。これにより、更新プログラム３３を、第１ＯＳ３１の一部として、或いは第１ＯＳ３１上で実行されるプログラムとは異なり、比較的容易に設計することができる。 Also, the boot program is selected and executed by the BIOS 30. Accordingly, the update program 33 can be designed relatively easily, unlike a program executed as a part of the first OS 31 or on the first OS 31.
　また、ＯＳ更新装置１０は、サーバ２１とともに産業用コンピュータシステム１００を構成した。この産業用コンピュータシステム１００によれば、サーバ２１がデータを配信するため、多数のＯＳ更新装置１０について容易にＯＳを更新することができる。 Further, the OS update device 10 constitutes an industrial computer system 100 together with the server 21. According to the industrial computer system 100, since the server 21 distributes data, the OS can be easily updated for a large number of OS update devices 10.
　また、ＯＳ更新装置１０は、予め規定された更新条件が成立すると、再起動してＯＳを更新した。更新条件として、深夜又は休日の日時を過ぎたことを設定すれば、その日時の直後にＯＳが更新される。このため、作業者がＯＳを更新する時刻において作業する必要がなく、作業負担を軽減することができる。 In addition, the OS update device 10 restarts and updates the OS when a predetermined update condition is satisfied. If the update condition is set to have passed the date of midnight or holiday, the OS is updated immediately after that date. For this reason, it is not necessary for the worker to work at the time when the OS is updated, and the work burden can be reduced.
　また、更新条件として、サーバ２１から特定の情報を受信することを設定すれば、サーバ２１から複数のＯＳ更新装置１０に当該特定の情報を送信することで、これらのＯＳ更新装置１０すべてのＯＳを一括して更新することができる。ＯＳ更新装置１０のＯＳを１台ずつ更新する場合には、更新作業に要する時間が台数に比例して増加してしまう。これに対して、一括して更新すれば、台数が増加しても更新作業にかかる時間は一定であるため、特に台数が多い場合には大幅に作業時間を削減することができる。 Also, if the update condition is set to receive specific information from the server 21, the OS 21 can transmit all the specific information from the server 21 to a plurality of OS update devices 10, thereby Can be updated in a batch. When the OS of the OS update device 10 is updated one by one, the time required for the update operation increases in proportion to the number of units. On the other hand, if the update is performed in a batch, the time required for the update work is constant even if the number of units increases, so that the operation time can be significantly reduced particularly when the number of units is large.
　また、ＯＳ更新装置１０は、予め第２ＯＳ３２をダウンロードした上で、更新条件が成立したときにＯＳを更新した。ＯＳを更新している間はＯＳ更新装置１０が動作を停止するため、ＯＳを更新する処理を開始してから通信路２０を経由して第２ＯＳ３２をダウンロードすると、少なくともダウンロードにかかる時間だけＯＳ更新装置１０の動作が停止して、停止時間が長期化してしまう。さらに、ダウンロード中に通信エラーが生じた場合には、ＯＳを更新する処理が中断してしまう。そのため、本実施の形態では、予め第２ＯＳ３２をダウンロードしておいて、ＯＳ更新処理においては第２ＯＳ３２をＯＳ記憶部１６に書き込むことで、ＯＳ更新装置１０の停止時間を短縮することができる。 Further, the OS update device 10 updates the OS when the update condition is satisfied after downloading the second OS 32 in advance. Since the OS update device 10 stops operating while the OS is being updated, when the second OS 32 is downloaded via the communication path 20 after starting the OS update process, the OS is updated at least for the time required for the download. The operation of the apparatus 10 stops, and the stop time is prolonged. Furthermore, if a communication error occurs during download, the process for updating the OS is interrupted. Therefore, in the present embodiment, the second OS 32 is downloaded in advance, and the second OS 32 is written in the OS storage unit 16 in the OS update process, so that the stop time of the OS update device 10 can be shortened.
　以上、本発明の実施の形態について説明したが、本発明は上記実施の形態によって限定されるものではない。 As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.
