Description
本発明は、監視制御システム、マスタ監視制御装置、スレーブ監視制御装置、集中監視制御装置、及び、監視制御方法に関する。 The present invention relates to a monitoring control system, a master monitoring control device, a slave monitoring control device, a centralized monitoring control device, and a monitoring control method.
光海底ケーブル等の波長多重伝送システムでは、トランスポンダの波長の異なる信号を多重化して、収容可能な通信トラフィックを増加させることができる。 In a wavelength division multiplexing transmission system such as an optical submarine cable, signals having different transponder wavelengths can be multiplexed to increase communication traffic that can be accommodated.
トランスポンダの波長の異なる信号を多重化する波長多重伝送システムの一例が、特許文献１に開示されている。特許文献１の波長多重伝送制御システムは、２台の端局装置と、端局装置間で接続される光伝送路とを備える。各端局装置は、それぞれ異なる特定波長でデータ伝送を行う複数のトランスポンダと、各トランスポンダの光信号波長の多重・分離を行う波長多重分離部と、トランスポンダ及び波長多重分離部の監視制御を行う監視制御部とを備える。波長多重伝送制御システムは、以下のように動作する。 An example of a wavelength multiplexing transmission system that multiplexes signals having different wavelengths of transponders is disclosed in Patent Document 1. The wavelength division multiplexing transmission control system of Patent Document 1 includes two terminal devices and an optical transmission path connected between the terminal devices. Each terminal device has a plurality of transponders that perform data transmission at different specific wavelengths, a wavelength demultiplexing unit that multiplexes / demultiplexes the optical signal wavelength of each transponder, and a monitor that performs monitoring control of the transponder and wavelength demultiplexing unit And a control unit. The wavelength division multiplexing control system operates as follows.
１台の端局装置は、同一光信号波長を利用するトランスポンダの対の一方を備える。トランスポンダは、対の他方のトランスポンダとデータの送受信を行う。波長多重分離部は、送信光信号を多重化して光伝送路に送信する一方、光伝送路から受信した光信号を波長分離する。監視制御部は、トランスポンダの状態を確認し、トランスポンダの設定を変更する。 One terminal device includes one of a pair of transponders that use the same optical signal wavelength. The transponder transmits / receives data to / from the other transponder in the pair. The wavelength demultiplexing unit multiplexes the transmission optical signal and transmits the multiplexed signal to the optical transmission path, while wavelength-separating the optical signal received from the optical transmission path. The monitoring control unit confirms the state of the transponder and changes the setting of the transponder.
多数の監視制御対象を有する監視制御システムの一例が、特許文献２に開示されている。特許文献２の系統監視制御システムでは、多数の監視制御対象であるノードが通信路で接続されている。通信路は、１台の監視制御センターをルートとし、末端の需要家に対応するノードをリーフとする、多段階層のツリー構造を有する。系統監視制御システムは、以下のように動作する。 An example of a supervisory control system having a large number of supervisory control objects is disclosed in Patent Document 2. In the system monitoring control system of Patent Document 2, a large number of nodes that are monitoring control targets are connected by communication paths. The communication path has a multi-level tree structure in which one monitoring control center is a root and a node corresponding to a terminal consumer is a leaf. The grid monitoring control system operates as follows.
監視制御対象である１台のノードは、もし下位の階層（リーフ側）があれば、通信路で直接接続された１階層下位のすべてのノードと通信を行う。そして、ノードは、下位のノードから監視情報を収集するか、又は、下位のノードへ制御情報を分配する。監視制御対象である１台のノードは、通信路で直接接続された１階層上位（ルート側）の１台のノードと通信を行う。そして、ノードは、そのノード及び下位のノードからの監視情報を集約して上位のノードに報告するか、又は、そのノード及び下位のノードへの制御情報を集約して上位のノードから受け取る。 If there is a lower hierarchy (leaf side), one node that is the object of monitoring control communicates with all nodes that are directly connected via the communication path. Then, the node collects monitoring information from the lower nodes or distributes the control information to the lower nodes. One node that is a monitoring control target communicates with one node that is directly connected via a communication path and that is one level higher (root side). Then, the node aggregates the monitoring information from the node and the lower node and reports it to the upper node, or collects the control information for the node and the lower node and receives it from the upper node.
特許文献１に開示されている技術では、トランスポンダの信号波長を多重化すると、トランスポンダの装置数も増加する。トランスポンダの装置数が増加すると、監視制御部の負荷が増大するという問題がある。又、トランスポンダに監視制御部と同じサブネットのＩＰアドレスを付与する場合、トランスポンダの装置数が大幅に増加すると、ＩＰアドレスが不足するという問題もある。 In the technique disclosed in Patent Document 1, if the transponder signal wavelengths are multiplexed, the number of transponder devices also increases. When the number of transponder devices increases, there is a problem that the load on the monitoring control unit increases. In addition, when the IP address of the same subnet as the monitoring control unit is assigned to the transponder, there is a problem that the IP address is insufficient when the number of transponder devices is significantly increased.
一方、特許文献２に開示されている技術では、監視制御対象である電力ネットワークを構成するノードと１対１に対応する監視制御器が、電力ネットワークと同じトポロジーの多階層のツリー構造を有する通信路で接続されている。各監視制御器は、その監視制御器及び下位階層の監視制御器の監視制御情報を集約して、上位階層の監視制御器と通信する。従って、特許文献２に開示されている技術では、１台の監視制御器の負荷を軽減することができる。しかし、監視制御センターの直下に存在する監視制御器数は、電力ネットワークのトポロジーに従って決定されてしまい、監視制御システムとして独立して決定できないので、１台の監視制御器が処理し得る負荷を考慮して監視制御装置の装置数を決めることができないという問題がある。 On the other hand, in the technique disclosed in Patent Document 2, the monitoring controller that has a one-to-one correspondence with the nodes constituting the power network to be monitored and controlled has a multi-level tree structure having the same topology as the power network. Connected by road. Each supervisory controller aggregates supervisory control information of the supervisory controller and the supervisory controller in the lower hierarchy and communicates with the supervisory controller in the upper hierarchy. Therefore, with the technique disclosed in Patent Document 2, the load on one monitoring controller can be reduced. However, the number of supervisory controllers that exist directly under the supervisory control center is determined according to the topology of the power network and cannot be determined independently as a supervisory control system, so the load that can be handled by one supervisory controller is taken into consideration. Thus, there is a problem that the number of monitoring control devices cannot be determined.
本発明の目的は、複数の監視制御対象機器の監視制御において、全ての監視制御対象機器を集中して監視制御する集中監視制御装置に対する負荷を抑制し、１台の監視制御装置が処理し得る負荷を考慮して監視制御装置の装置数を決めることができ、又、監視制御対象に割り当てが必要な集中監視制御装置と同じサブネットに属するＩＰアドレス数を１個にすることができる監視制御システム、マスタ監視制御装置、スレーブ監視制御装置、集中監視制御装置、及び、監視制御方法を提供することにある。 An object of the present invention is to suppress a load on a centralized monitoring control device that centrally monitors and controls all devices to be monitored and controlled in a monitoring control of a plurality of devices to be monitored and controlled, and one monitoring control device can process.

以下、本発明の実施形態について図面を参照して詳細に説明する。尚、すべての図面において、同様な構成要素には同様の符号を付し、適宜説明を省略する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.
図１は、本発明の実施形態における監視制御システムの構成を示すブロック図である。本実施形態における監視制御システムは、集中監視制御装置５と、マスタ監視制御装置１１０と、スレーブ監視制御装置２１０と、監視制御対象装置１１６、２１６とを備える。 FIG. 1 is a block diagram showing a configuration of a monitoring control system according to an embodiment of the present invention. The monitoring control system in this embodiment includes a centralized monitoring control device 5, a master monitoring control device 110, a slave monitoring control device 210, and monitoring control target devices 116 and 216.
尚、図１は、本発明の実施形態における監視制御システムの最小の構成を示す。すなわち、図１では、１台のマスタ監視制御装置と、１台のスレーブ監視制御装置と、２台の監視制御対象装置とを含む構成を例示しているが、本実施の形態はこれに限定されない。以降の説明から明らかなように、集中監視制御装置には、複数のマスタ監視制御装置がカスケード接続されてもよい。マスタ監視制御装置には、１台以上のスレーブ監視制御装置のみでなく、他のマスタ監視制御装置が接続されてもよい。マスタ監視制御装置及びスレーブ監視制御装置には、それぞれ複数の監視制御対象装置が接続されてもよい。 FIG. 1 shows the minimum configuration of the monitoring control system according to the embodiment of the present invention. That is, FIG. 1 illustrates a configuration including one master monitoring control device, one slave monitoring control device, and two monitoring control target devices, but the present embodiment is limited to this. Not. As will be apparent from the following description, a plurality of master monitoring control devices may be cascade-connected to the centralized monitoring control device. In addition to one or more slave monitoring control devices, other master monitoring control devices may be connected to the master monitoring control device. A plurality of monitoring control target devices may be connected to the master monitoring control device and the slave monitoring control device, respectively.
集中監視制御装置５は、保守者に対し、すべての監視制御対象機器の監視及び制御のためのインタフェースを提供する。集中監視制御装置５は、１台のマスタ監視制御装置１１０とのみ直接接続される。集中監視制御装置５は、マスタ監視制御装置１１０を経由して、監視制御対象である監視制御対象機器１１６の監視制御情報を送受信する。集中監視制御装置５は、マスタ監視制御装置１１０、スレーブ監視制御装置２１０を経由して、監視制御対象である監視制御対象機器２１６の監視制御情報を送受信する。 The centralized monitoring control device 5 provides an interface for monitoring and controlling all the devices to be monitored and controlled to the maintenance person. The centralized monitoring control device 5 is directly connected only to one master monitoring control device 110. The centralized monitoring control device 5 transmits and receives monitoring control information of the monitoring control target device 116 that is a monitoring control target via the master monitoring control device 110. The centralized monitoring control device 5 transmits and receives monitoring control information of the monitoring control target device 216 that is a monitoring control target via the master monitoring control device 110 and the slave monitoring control device 210.
又、マスタ監視制御装置１１０が監視制御対象装置１１６以外の監視制御対象装置に直接接続されるならば、集中監視制御装置５は、マスタ監視制御装置１１０を経由して、監視制御対象装置１１６以外の監視制御対象装置の監視制御情報を送受信する。又、マスタ監視制御装置１１０がスレーブ監視装置２１０以外のスレーブ監視制御装置に直接接続されるならば、集中監視制御装置５は、マスタ監視制御装置１１０及びスレーブ監視装置２１０以外のスレーブ監視制御装置を経由して、スレーブ監視装置２１０以外のスレーブ監視制御装置に直接接続された１台以上の監視制御対象装置の監視制御情報を送受信する。又、マスタ監視制御装置１１０が別のマスタ監視制御装置にカスケード接続されるならば、集中監視制御装置５は、マスタ監視制御装置１１０及び別のマスタ監視制御装置を経由して、別のマスタ監視制御装置に直接接続された１台以上の監視制御対象装置、及び、別のマスタ監視制御装置に直接接続されたスレーブ監視装置に直接接続された１台以上の監視制御対象装置の監視制御情報を送受信する。 If the master supervisory control device 110 is directly connected to a supervisory control target device other than the supervisory control target device 116, the central supervisory control device 5 passes through the master supervisory control device 110 and other than the supervisory control target device 116. The monitoring control information of the monitoring control target device is transmitted and received. Further, if the master monitoring control device 110 is directly connected to a slave monitoring control device other than the slave monitoring device 210, the centralized monitoring control device 5 can connect slave monitoring control devices other than the master monitoring control device 110 and the slave monitoring device 210. Via, the monitoring control information of one or more monitoring control target devices directly connected to slave monitoring control devices other than the slave monitoring device 210 is transmitted and received. If the master monitoring control device 110 is cascade-connected to another master monitoring control device, the centralized monitoring control device 5 passes another master monitoring control device via the master monitoring control device 110 and another master monitoring control device. Monitoring control information of one or more monitoring control target devices directly connected to the control device and one or more monitoring control target devices directly connected to a slave monitoring device directly connected to another master monitoring control device Send and receive.
尚、集中監視制御装置５は、例えば、ＥＭＳ（Element Management System）、又は、ＮＭＳ（Network Management System）を含んでもよい。 The centralized monitoring control device 5 may include, for example, an EMS (Element Management System) or an NMS (Network Management System).
マスタ監視制御装置１１０は、マスタ監視制御装置１１０に直接接続される監視制御対象装置１１６、マスタ監視制御装置１１０に直接接続されるスレーブ監視制御装置２１０に接続される監視制御対象装置２１６と、集中監視制御装置５との間で通信される監視制御情報を集約・分離して転送する。ここで、「集約・分離」とは、本来であれば、監視制御対象装置毎に独立した、監視制御対象装置と集中監視制御装置５との間の監視制御情報を、複数の監視制御対象装置毎に１個の監視制御情報に集約したり、集約した監視制御情報を１台の監視制御対象装置毎に１個の監視制御情報に分離したりすることを指す。 The master monitoring control device 110 includes a monitoring control target device 116 that is directly connected to the master monitoring control device 110, a monitoring control target device 216 that is connected to the slave monitoring control device 210 that is directly connected to the master monitoring control device 110, and a centralized control. The monitoring control information communicated with the monitoring control device 5 is aggregated and separated and transferred. Here, “aggregation / separation” originally refers to monitoring control information between the monitoring control target device and the centralized monitoring control device 5 that is independent for each monitoring control target device. It means that the information is aggregated into one piece of monitoring control information every time, or the collected monitoring control information is separated into one piece of monitoring control information for each monitoring control target device.
又、監視制御対象装置１１６以外にマスタ監視制御装置１１０に直接接続される監視制御対象装置があれば、マスタ監視制御装置１１０は、監視制御対象装置１１６以外の監視制御対象装置と、集中監視制御装置５との間で通信される監視制御情報を集約・分離して転送する。又、スレーブ監視制御装置２１０以外にマスタ監視制御装置１１０に直接接続されるスレーブ監視制御装置があれば、マスタ監視制御装置１１０は、スレーブ監視制御装置２１０以外のスレーブ監視制御装置に直接接続される１台以上の監視制御対象装置と、集中監視制御装置５との間で通信される監視制御情報を集約・分離して転送する。 In addition, if there is a monitoring control target device that is directly connected to the master monitoring control device 110 other than the monitoring control target device 116, the master monitoring control device 110 and the monitoring control target device other than the monitoring control target device 116 and the centralized monitoring control. The monitoring control information communicated with the device 5 is aggregated and separated and transferred. In addition, if there is a slave monitoring control device that is directly connected to the master monitoring control device 110 other than the slave monitoring control device 210, the master monitoring control device 110 is directly connected to a slave monitoring control device other than the slave monitoring control device 210. Monitoring control information communicated between one or more monitoring control target devices and the centralized monitoring control device 5 is aggregated and separated and transferred.
マスタ監視制御装置１１０が集中監視制御装置５と接続される場合、マスタ監視制御装置１１０は、マスタ監視制御装置１１０に接続される他のマスタ監視制御装置と、集中監視制御装置５との間で通信される監視制御情報の集中監視制御装置５以外のＩＰアドレスを集中監視制御装置５側サブネットのマスタ監視制御装置１１０のＩＰアドレスに置き換えて転送する。このとき同時に、マスタ監視制御装置１１０は、ポート番号も適当なポート番号に置き換える。ここで、集中監視制御装置５に接続されるマスタ監視制御装置は、マスタ監視制御装置１１０だけである。また、マスタ監視制御装置１１０の、集中監視制御装置５側のサブネットの、マスタ監視制御装置１１０のＩＰアドレス以外のＩＰアドレス、他のマスタ監視制御装置のＩＰアドレス、スレーブ監視制御装置２１０のＩＰアドレス、及び、監視制御対象装置のＩＰアドレスは、集中監視制御装置５側のサブネットに属さないＩＰアドレスである。 When the master monitoring control device 110 is connected to the centralized monitoring control device 5, the master monitoring control device 110 is connected between the master monitoring control device 5 and another master monitoring control device connected to the master monitoring control device 110. The IP address other than the centralized monitoring control device 5 of the monitoring control information to be communicated is replaced with the IP address of the master monitoring control device 110 of the centralized monitoring control device 5 side subnet and transferred. At the same time, the master monitoring control device 110 also replaces the port number with an appropriate port number. Here, the master monitoring control device 110 is the only master monitoring control device connected to the centralized monitoring control device 5. Also, an IP address other than the IP address of the master monitoring control device 110, the IP address of the other master monitoring control device, and the IP address of the slave monitoring control device 210 of the master monitoring control device 110 in the subnet on the centralized monitoring control device 5 side. The IP address of the monitoring control target device is an IP address that does not belong to the subnet on the centralized monitoring control device 5 side.
尚、ここでは、マスタ監視制御装置１１０がＩＰアドレスとポート番号の置き換え機能（ＩＰマスカレード）を備える構成を例示しているが、本実施の形態はこれに限定されない。ＩＰマスカレード機能を備えた装置が、マスタ監視制御装置１１０と集中監視制御装置５との間に独立して存在してもよい。 Here, the master monitoring control device 110 is illustrated with a configuration having an IP address and port number replacement function (IP masquerade), but the present embodiment is not limited to this. A device having an IP masquerade function may exist independently between the master monitoring control device 110 and the centralized monitoring control device 5.
マスタ監視制御装置１１０は、集中監視制御装置５に接続され、更に、マスタ監視制御装置１１０が末端に位置する場合を除き、別のマスタ監視制御装置と接続される。各マスタ監視制御装置は、そのマスタ監視制御装置より集中監視制御装置５から遠い側のマスタ監視制御装置と集中監視制御装置５との間の監視制御情報を中継する。 The master monitoring control device 110 is connected to the centralized monitoring control device 5 and further connected to another master monitoring control device except when the master monitoring control device 110 is located at the end. Each master monitoring control device relays monitoring control information between the master monitoring control device 5 and the master monitoring control device 5 farther from the central monitoring control device 5 than the master monitoring control device.
マスタ監視制御装置１１０は、スイッチＢ１１２と、スイッチＡ１１１と、監視制御情報転送手段１１３とを備える。マスタ監視制御装置１１０は、集中監視制御装置５、又は、他のマスタ監視制御装置に、スイッチＡ１１１を経由して接続される。マスタ監視制御装置１１０は、１台以上の監視制御対象装置１１６、及び、１台以上のスレーブ監視制御装置２１０に、スイッチＢ１１２を経由して接続される。監視制御情報転送手段１１３は、監視制御対象装置毎の監視制御情報を集約又は分離して転送する。 The master supervisory control device 110 includes a switch B112, a switch A111, and a supervisory control information transfer unit 113. The master monitoring control device 110 is connected to the centralized monitoring control device 5 or another master monitoring control device via the switch A111. The master monitoring control device 110 is connected to one or more monitoring control target devices 116 and one or more slave monitoring control devices 210 via a switch B112. The monitoring control information transfer unit 113 aggregates or separates and transfers the monitoring control information for each monitoring control target device.
尚、スイッチＢ１１２、及び、スイッチＡ１１１は、例えば、ルータ、Ｌ３スイッチ（Layer 3 Switch）、又は、Ｌ２スイッチ（Layer 2 Switch）であってもよい。 The switch B112 and the switch A111 may be, for example, a router, an L3 switch (Layer 3 Switch), or an L2 switch (Layer 2 Switch).

次に、本実施形態の動作を説明する。 Next, the operation of this embodiment will be described.
図２は、本実施形態における監視制御システムのマスタ監視制御装置の動作を示すフローチャートである。尚、ここでは、マスタ監視制御装置１１０を例に説明する。マスタ監視制御装置１１０には、他のマスタ監視制御装置が接続される場合がある。その場合も、全てのマスタ監視制御装置について、動作はマスタ監視制御装置１１０の動作と同様である。 FIG. 2 is a flowchart showing the operation of the master supervisory control device of the supervisory control system in the present embodiment. Here, the master monitoring control device 110 will be described as an example. There are cases where another master monitoring control device is connected to the master monitoring control device 110. Even in this case, the operation is the same as that of the master monitoring control device 110 for all the master monitoring control devices.
マスタ監視制御装置１１０のスイッチＡ１１１は、集中監視制御装置５から監視制御命令を受信すると（ステップＳ２１：Ｙｅｓ）、受信した監視制御命令をマスタ監視制御装置１１０の監視制御情報転送手段１１３、及び、もしあれば、後段のマスタ監視制御装置に転送する（ステップＳ２２）。 When the switch A111 of the master monitoring control device 110 receives the monitoring control command from the centralized monitoring control device 5 (step S21: Yes), the received monitoring control command is sent to the monitoring control information transfer means 113 of the master monitoring control device 110, and If there is, it is transferred to the master monitoring control device at the subsequent stage (step S22).
監視制御情報転送手段１１３は、スイッチＡ１１１から監視制御命令を受け取り、受け取った監視制御命令を監視制御対象装置毎の監視制御命令に分離する（ステップＳ２３）。 The supervisory control information transfer unit 113 receives the supervisory control instruction from the switch A111, and separates the received supervisory control instruction into supervisory control instructions for each supervisory control target device (step S23).
監視制御情報転送手段１１３は、分離された監視制御命令の目的である監視制御対象装置がマスタ監視制御装置１１０に直接接続されるならば、分離された監視制御命令を監視制御命令の目的である監視制御対象装置１１６に、スイッチＢ１１２を経由して転送する（ステップＳ２４）。 The supervisory control information transfer means 113 is the objective of the supervisory control instruction if the supervisory control target device that is the objective of the separated supervisory control instruction is directly connected to the master supervisory control apparatus 110. The data is transferred to the monitoring control target device 116 via the switch B112 (step S24).
一方、監視制御情報転送手段１１３は、分離された監視制御命令の目的である監視制御対象装置がマスタ監視制御装置１１０に直接接続されるスレーブ監視制御装置（この場合は、スレーブ監視制御装置２１０）に直接接続されるならば、分離された監視制御命令をスレーブ監視制御装置毎の監視制御命令に集約して、監視制御命令の目的である監視制御対象装置（この場合は、監視制御対象装置２１６）に直接接続されるスレーブ監視制御装置（この場合は、スレーブ監視制御装２１０）に、スイッチＢ１１２を経由して転送する（ステップＳ２５）。 On the other hand, the supervisory control information transfer means 113 is a slave supervisory control device (in this case, the slave supervisory control device 210) in which the supervisory control target device that is the purpose of the separated supervisory control command is directly connected to the master supervisory control device 110. Are directly connected to the monitoring control command for each slave monitoring control device, the separated monitoring control commands are aggregated into the monitoring control target device (in this case, the monitoring control target device 216). The data is transferred to the slave monitoring control device (in this case, the slave monitoring control device 210) directly connected via the switch B112 (step S25).
スイッチＡ１１１は、監視制御命令を受信しなければ、ステップＳ２６の処理に移る（ステップＳ２１：Ｎｏ）。 If the switch A111 does not receive the monitoring control command, the switch A111 proceeds to the process of step S26 (step S21: No).
マスタ監視制御装置１１０のスイッチＡ１１１は、マスタ監視制御装置１１０の監視制御情報転送手段１１３、又は、もしあれば、後続のマスタ監視制御装置から監視制御応答を受信すると（ステップＳ２６：Ｙｅｓ）、受信した監視制御応答を集中監視制御装置５、又は、もしあれば、前段のマスタ監視制御装置（この場合は、存在しない）に転送する（ステップＳ２７）。 The switch A111 of the master monitoring control device 110 receives the monitoring control response from the monitoring control information transfer means 113 of the master monitoring control device 110 or the succeeding master monitoring control device, if any (step S26: Yes). The monitored control response is transferred to the centralized monitoring control device 5 or the master monitoring control device in the preceding stage (in this case, it does not exist) (step S27).
尚、ここで、集中監視制御装置５に転送する場合には、監視制御応答のソースＩＰアドレスをマスタ監視制御装置の集中監視制御装置５側サブネットのＩＰアドレスに変換する。また、ソースポート番号を適当なポート番号に変換する。尚、このＩＰアドレス及びポート番号の変換は、ＩＰマスカレードとして、当業者に広く知られているので、ここでは説明しない。 Here, when transferring to the centralized monitoring control apparatus 5, the source IP address of the monitoring control response is converted to the IP address of the centralized monitoring control apparatus 5 side subnet of the master monitoring control apparatus. Also, the source port number is converted into an appropriate port number. This IP address and port number conversion is well known to those skilled in the art as IP masquerading, and therefore will not be described here.
スイッチＡ１１１は、監視制御応答を受信しなければ、ステップＳ３１の処理に移る（ステップＳ２６：Ｎｏ）。 If the switch A111 does not receive the monitoring control response, the process proceeds to step S31 (step S26: No).
マスタ監視制御装置１１０のスイッチＢ１１２は、監視制御情報転送手段１１３から監視制御命令を受信すると（ステップＳ３１：Ｙｅｓ）、受信した監視制御命令をマスタ監視制御装置１１０に直接接続された監視制御対象装置（この場合は、監視制御対象装置１１６）、又は、マスタ監視制御装置１１０に直接接続されたスレーブ監視制御装置（この場合は、スレーブ監視制御装置２１０）に転送する（ステップＳ３２）。 When the switch B112 of the master supervisory control device 110 receives the supervisory control command from the supervisory control information transfer unit 113 (step S31: Yes), the supervisory control target device directly connected to the master supervisory control device 110 receives the supervisory control command. (In this case, the monitoring control target device 116) or the slave monitoring control device (in this case, the slave monitoring control device 210) directly connected to the master monitoring control device 110 is transferred (step S32).
スイッチＢ１１２は、監視制御命令を受信しなければ、ステップＳ３６の処理に移る（ステップＳ３１：Ｎｏ）。 If the switch B 112 does not receive the supervisory control command, the switch B 112 proceeds to the process of step S36 (step S31: No).
マスタ監視制御装置１１０のスイッチＢ１１２は、マスタ監視制御装置１１０に直接接続された監視制御対象装置（この場合は、監視制御対象装置１１６）、又は、マスタ監視制御装置１１０に直接接続されたスレーブ監視制御装置（この場合は、スレーブ監視制御装置２１０）から監視制御応答を受信すると（ステップＳ３６：Ｙｅｓ）、受信した監視制御応答をマスタ監視制御装置１１０の監視制御情報転送手段１１３に転送する（ステップＳ３７）。 The switch B112 of the master monitoring control device 110 is a monitoring control target device (in this case, the monitoring control target device 116) directly connected to the master monitoring control device 110 or a slave monitoring directly connected to the master monitoring control device 110. When the monitoring control response is received from the control device (in this case, the slave monitoring control device 210) (step S36: Yes), the received monitoring control response is transferred to the monitoring control information transfer means 113 of the master monitoring control device 110 (step S36). S37).
マスタ監視制御装置１１０の監視制御情報転送手段１１３は、受信した監視制御対象装置（この場合は、監視制御対象装置１１６）の監視制御応答をマスタ監視制御装置１１０毎の監視制御応答に集約する。その際、もしあれば、スレーブ監視制御装置（この場合は、スレーブ監視制御装置２１０）毎の監視制御応答があれば、その監視制御応答も集約する。そして、集中監視制御装置５、又は、もしあれば、前段のマスタ監視制御装置（この場合は、存在しない）に転送する（ステップＳ３８）。 The monitoring control information transfer unit 113 of the master monitoring control device 110 collects the received monitoring control responses of the monitoring control target devices (in this case, the monitoring control target device 116) into the monitoring control responses for each master monitoring control device 110. At that time, if there is a monitoring control response for each slave monitoring control device (in this case, the slave monitoring control device 210), the monitoring control responses are also collected. Then, the data is transferred to the centralized monitoring control device 5 or the master monitoring control device in the preceding stage (in this case, it does not exist) (step S38).
スイッチＢ１１２は、監視制御応答を受信しなければ、ステップＳ２１に戻る（ステップＳ３６：Ｎｏ）。 If the switch B112 does not receive the monitoring control response, the process returns to step S21 (step S36: No).
図３は、本実施形態における監視制御システムのスレーブ監視制御装置の動作を示すフローチャートである。尚、ここでは、スレーブ監視制御装置２１０を例に説明する。マスタ監視制御装置１１０には、複数のスレーブ監視制御装置が接続される場合がある。その場合も、全てのスレーブ監視制御装置について、動作はスレーブ監視制御装置２１０の動作と同様である。 FIG. 3 is a flowchart showing the operation of the slave monitoring control device of the monitoring control system in the present embodiment. Here, the slave monitoring control device 210 will be described as an example. A plurality of slave monitoring control devices may be connected to the master monitoring control device 110. Also in this case, the operation is the same as that of the slave monitoring control device 210 for all the slave monitoring control devices.
スレーブ監視制御装置２１０のスイッチＣ２１２は、監視制御情報転送手段２１３から監視制御命令を受信すると（ステップＳ４１：Ｙｅｓ）、受信した監視制御命令をスレーブ監視制御装置２１０に直接接続された監視制御対象装置（この場合は、監視制御対象装置２１６）に転送する（ステップＳ４２）。 When the switch C212 of the slave monitoring control device 210 receives the monitoring control command from the monitoring control information transfer unit 213 (step S41: Yes), the monitoring control target device directly connected to the slave monitoring control device 210 receives the monitoring control command received (In this case, the monitoring control target device 216) is transferred (step S42).
スイッチＣ２１２は、監視制御命令を受信しなければ、ステップＳ４６の処理に移る（ステップＳ４１：Ｎｏ）。 If the switch C212 does not receive the supervisory control command, the switch C212 proceeds to the process of step S46 (step S41: No).
スレーブ監視制御装置２０のスイッチＣ２１２は、スレーブ監視制御装置２１０に直接接続された監視制御対象装置（この場合は、監視制御対象装置２１６）から監視制御応答を受信すると（ステップＳ４６：Ｙｅｓ）、受信した監視制御応答をスレーブ監視制御装置２１０の監視制御情報転送手段２１３に転送する（ステップＳ４７）。 When the switch C212 of the slave monitoring control device 20 receives a monitoring control response from the monitoring control target device (in this case, the monitoring control target device 216) directly connected to the slave monitoring control device 210 (step S46: Yes), the reception is received. The monitored control response is transferred to the monitoring control information transfer means 213 of the slave monitoring control device 210 (step S47).
スレーブ監視制御装置２１０の監視制御情報転送手段２１３は、受信した監視制御対象装置（この場合は、監視制御対象装置２１６）の監視制御応答をスレーブ監視制御装置２１０毎の監視制御応答に集約して、スレーブ監視制御装置２１０に直接接続されるマスタ監視制御装置１１０に転送する。 The monitoring control information transfer unit 213 of the slave monitoring control device 210 aggregates the received monitoring control response of the monitoring control target device (in this case, the monitoring control target device 216) into the monitoring control response for each slave monitoring control device 210. Then, the data is transferred to the master monitoring control device 110 that is directly connected to the slave monitoring control device 210.
スイッチＣ２１２は、監視制御応答を受信しなければ、ステップＳ４１に戻る（ステップＳ４６：Ｎｏ）。 If the switch C212 does not receive the monitoring control response, the process returns to step S41 (step S46: No).
以上説明したように、本実施形態における監視制御システムでは、集中監視装置は、すべての監視制御対象装置に対する監視制御命令を１台のマスタ監視制御装置１１０に対して集約して要求できる。その結果、監視制御情報の通信に係るパケット数やオーバーヘッドを削減でき、集中制御監視装置に対する負荷を抑制することが可能である。 As described above, in the monitoring control system according to the present embodiment, the centralized monitoring device can collect and request monitoring control commands for all the monitoring control target devices from one master monitoring control device 110. As a result, it is possible to reduce the number of packets and overhead related to the monitoring control information communication, and to suppress the load on the centralized control monitoring apparatus.
又、本実施形態における監視制御システムでは、１台のマスタ監視制御装置又はスレーブ監視制御装置が処理し得る監視制御対象装置数等を考慮して、マスタ監視制御装置及びスレーブ監視制御装置の装置数を決めることができる。例えば、２７台の監視制御対象装置が存在する場合、１台のマスタ監視制御装置又はスレーブ監視制御装置が処理し得る監視制御対象装置数が３台ならば、９台のマスタ監視制御装置及びスレーブ監視制御装置を用意すればよい。 In the monitoring control system according to the present embodiment, the number of master monitoring control devices and slave monitoring control devices in consideration of the number of monitoring control target devices that can be processed by one master monitoring control device or slave monitoring control device. Can be decided. For example, if there are 27 monitoring control target devices, if the number of monitoring control target devices that can be processed by one master monitoring control device or slave monitoring control device is three, nine master monitoring control devices and slaves A monitoring control device may be prepared.
