実施の形態１．
　図１は、実施の形態１におけるエレベーターシステム１の例を示す図である。図１は、エレベーターシステム１が４台のエレベーター装置を備える例を示す。例えば、エレベーターシステム１は、エレベーター装置としてＦ号機、Ｇ号機、Ｈ号機、及びＩ号機を備える。エレベーターシステム１が備えるエレベーター装置の台数は４台に限定されない。例えば、エレベーターシステム１は８台のエレベーター装置を備えても良い。 Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator system 1 according to the first embodiment. FIG. 1 shows an example in which the elevator system 1 includes four elevator devices. For example, the elevator system 1 includes units F, G, H, and I as elevator devices. The number of elevator devices included in the elevator system 1 is not limited to four. For example, the elevator system 1 may include eight elevator devices.
　エレベーターシステム１は、群管理基板２、制御基板３Ｆ～３Ｉ、乗場操作盤４ＦＧ、乗場操作盤４ＨＩ、乗場灯５、乗場釦６ＦＧ、乗場釦６ＨＩ、リレー基板７Ｆ、リレー基板７Ｈ、及び共通基板８を備える。更に、エレベーターシステム１は、ネットワーク２１、ネットワーク２２Ｆ及び２２Ｈ、ネットワーク２３Ｆ及び２３Ｈ、並びにネットワーク２４を備える。 The elevator system 1 includes a group management board 2, control boards 3F to 3I, a landing operation panel 4FG, a landing operation panel 4HI, a landing light 5, a landing button 6FG, a landing button 6HI, a relay board 7F, a relay board 7H, and a common board 8. To be equipped. Further, the elevator system 1 includes a network 21, networks 22F and 22H, networks 23F and 23H, and a network 24.
　群管理基板２は、システム全体の運行を管理する。群管理基板２は、群管理盤に実装される。制御基板３Ｆは、Ｆ号機の運行を制御する。例えば、Ｆ号機のかごは、制御基板３Ｆによって制御される。制御基板３Ｆは、Ｆ号機の制御盤に実装される。制御基板３Ｇは、Ｇ号機の運行を制御する。例えば、Ｇ号機のかごは、制御基板３Ｇによって制御される。制御基板３Ｇは、Ｇ号機の制御盤に実装される。 The group management board 2 manages the operation of the entire system. The group management board 2 is mounted on the group management board. The control board 3F controls the operation of Unit F. For example, the car of Unit F is controlled by the control board 3F. The control board 3F is mounted on the control panel of Unit F. The control board 3G controls the operation of the G unit. For example, the car of Unit G is controlled by the control board 3G. The control board 3G is mounted on the control panel of Unit G.
　制御基板３Ｈは、Ｈ号機の運行を制御する。例えば、Ｈ号機のかごは、制御基板３Ｈによって制御される。制御基板３Ｈは、Ｈ号機の制御盤に実装される。制御基板３Ｉは、Ｉ号機の運行を制御する。例えば、Ｉ号機のかごは、制御基板３Ｉによって制御される。制御基板３Ｉは、Ｉ号機の制御盤に実装される。 The control board 3H controls the operation of Unit H. For example, the car of Unit H is controlled by the control board 3H. The control board 3H is mounted on the control panel of Unit H. The control board 3I controls the operation of Unit I. For example, the car of Unit I is controlled by the control board 3I. The control board 3I is mounted on the control panel of Unit I.
　制御基板３Ｆ～３Ｉのそれぞれは、群管理基板２が有する群管理機能と同じ機能を有する。群管理基板２と制御基板３Ｆ～３Ｉとに対して、群管理機能を実行するための優先度が予め設定される。表１は、優先度の設定例を示す。 Each of the control boards 3F to 3I has the same function as the group management function of the group management board 2. The priority for executing the group management function is set in advance for the group management board 2 and the control boards 3F to 3I. Table 1 shows an example of setting the priority.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　表１に示す例では、群管理基板２の優先度が一番高い。優先度が一番高い基板の役割は、マスタ（ＭＳＴ）である。制御基板３Ｆの優先度は二番目に高い。優先度が二番目に高い基板の役割は、バックアップマスタ（ＢＫＭＳＴ）である。制御基板３Ｈの優先度は三番目に高い。優先度が三番目に高い基板の役割は、バックアップスレーブ（ＢＫＳＬＶ）である。他の制御基板の優先度は一番低い。優先度が一番低い基板の役割は、スレーブ（ＳＬＶ）である。 In the example shown in Table 1, the group management board 2 has the highest priority. The role of the substrate with the highest priority is the master (MST). The control board 3F has the second highest priority. The role of the board with the second highest priority is the backup master (BKMST). The control board 3H has the third highest priority. The role of the third highest priority board is the backup slave (BKSLV). Other control boards have the lowest priority. The role of the board with the lowest priority is the slave (SLV).
　群管理基板２及び制御基板３Ｆ～３Ｉのそれぞれには、群管理機能を有効及び無効に設定するための制御パラメータが備えられる。例えば、群管理基板２、制御基板３Ｆ、及び制御基板３Ｈのそれぞれでは、初期設定において、制御パラメータによって群管理機能が有効に設定される。制御基板３Ｇ及び制御基板３Ｉのそれぞれでは、初期設定において、制御パラメータによって群管理機能が無効に設定される。エレベーターシステム１では、群管理基板２及び制御基板３Ｆ～３Ｉの中で、群管理機能が有効に設定され且つ優先度が最も高い基板が群管理機能を実行する。本実施の形態に示す例では、基本的に、群管理基板２が群管理機能を実行する。群管理基板２が群管理機能を実行できなくなると、制御基板３Ｆの役割がＢＫＭＳＴからＭＳＴに繰り上がり、制御基板３Ｆが群管理機能を担う。 Each of the group management board 2 and the control boards 3F to 3I is provided with control parameters for setting the group management function to be valid and invalid. For example, in each of the group management board 2, the control board 3F, and the control board 3H, the group management function is effectively set by the control parameters in the initial setting. In each of the control board 3G and the control board 3I, the group management function is disabled by the control parameter in the initial setting. In the elevator system 1, among the group management boards 2 and the control boards 3F to 3I, the group management function is effectively set and the board having the highest priority executes the group management function. In the example shown in this embodiment, the group management board 2 basically executes the group management function. When the group management board 2 becomes unable to execute the group management function, the role of the control board 3F is shifted from BKMST to MST, and the control board 3F takes on the group management function.
　ネットワーク２１は、群管理基板２と制御基板３Ｆ～３Ｉとをリング型のトポロジーで接続する。ネットワーク２１は、伝送方向に応じた複数の信号線を備えても良い。ネットワーク２１の物理層は、例えばＬＡＮ（Ｌｏｃａｌ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）によって実現される。図１に示す例では、ネットワーク２１に関して、制御基板３Ｆは、群管理基板２と制御基板３Ｇとの間に配置される。制御基板３Ｇは、制御基板３Ｆと制御基板３Ｈとの間に配置される。制御基板３Ｈは、制御基板３Ｇと制御基板３Ｉとの間に配置される。制御基板３Ｉは、制御基板３Ｈと群管理基板２との間に配置される。 The network 21 connects the group management board 2 and the control boards 3F to 3I in a ring-shaped topology. The network 21 may include a plurality of signal lines according to the transmission direction. The physical layer of the network 21 is realized by, for example, a LAN (Local Area Network). In the example shown in FIG. 1, the control board 3F is arranged between the group management board 2 and the control board 3G with respect to the network 21. The control board 3G is arranged between the control board 3F and the control board 3H. The control board 3H is arranged between the control board 3G and the control board 3I.

The common signal is a signal required for all the units included in the elevator system 1. For example, an earthquake detector (not shown) is installed in a building equipped with an elevator system 1. The seismic signal output from the seismic detector is an example of a common signal. The seismic signal output from the seismic detector is input to the common board 8. As another example, a fire detector (not shown) is provided in a building equipped with an elevator system 1. The fire signal output from the fire detector is an example of a common signal. The fire signal output from the fire detector is input to the common board 8.
　ネットワーク２４は、共通基板８と群管理基板２と制御基板３Ｆ～３Ｉとをバス型のトポロジーで接続する。ネットワーク２４の物理層及びデータリンク層は、例えばＣＡＮによって実現される。 The network 24 connects the common board 8, the group management board 2, and the control boards 3F to 3I in a bus-type topology. The physical layer and data link layer of the network 24 are realized by, for example, CAN.
　図２は、群管理基板２の機能を説明するための図である。群管理基板２は、ノード判定部３１、割当部３２、指令部３３、離脱検出部３４、隔離検出部３５、転送部３６、及び復帰検出部３７を備える。以下に、図３から図８も参照し、エレベーターシステム１の機能について詳しく説明する。図３から図８は、実施の形態１におけるエレベーターシステム１の動作例を示すフローチャートである。図３は、役割がＭＳＴに設定された基板の動作例を示す。例えば、図３は群管理基板２の動作を示す。 FIG. 2 is a diagram for explaining the function of the group management board 2. The group management board 2 includes a node determination unit 31, an allocation unit 32, a command unit 33, a departure detection unit 34, an isolation detection unit 35, a transfer unit 36, and a return detection unit 37. Hereinafter, the functions of the elevator system 1 will be described in detail with reference to FIGS. 3 to 8. 3 to 8 are flowcharts showing an operation example of the elevator system 1 according to the first embodiment. FIG. 3 shows an operation example of the substrate whose role is set to MST. For example, FIG. 3 shows the operation of the group management board 2.
　ノード判定部３１は、制御基板３Ｆ～３Ｉに対して、ネットワーク２１を介して参入要求を送信する（Ｓ１０１）。参入要求は、群管理を行うために必要な制御基板への問い合わせである。例えば、Ｓ１０１では、群管理基板２からネットワーク２１に対して参入要求がブロードキャストされる。なお、Ｓ１０１の処理は、群管理基板２において定期的に行われる。 The node determination unit 31 transmits an entry request to the control boards 3F to 3I via the network 21 (S101). The entry request is an inquiry to the control board necessary for performing group management. For example, in S101, the entry request is broadcast from the group management board 2 to the network 21. The processing of S101 is periodically performed on the group management board 2.
　図４は、役割がＭＳＴに設定されていない制御基板の動作例を示す。例えば、図４は、制御基板３Ｆ～３Ｉのそれぞれの動作を示す。例えば、制御基板３Ｇでは、ネットワーク２１を介して参入要求を受信したか否かが判定される（Ｓ２０１）。Ｓ１０１でノード判定部３１が送信した参入要求を制御基板３Ｇが受信すると、Ｓ２０１でＹｅｓと判定される。制御基板３Ｇは、Ｓ２０１でＹｅｓと判定すると、群管理基板２に対してネットワーク２１を介して参入応答を送信する（Ｓ２０２）。 FIG. 4 shows an operation example of the control board whose role is not set to MST. For example, FIG. 4 shows the operation of each of the control boards 3F to 3I. For example, in the control board 3G, it is determined whether or not the entry request is received via the network 21 (S201). When the control board 3G receives the entry request transmitted by the node determination unit 31 in S101, it is determined to be Yes in S201. When the control board 3G determines Yes in S201, the control board 3G transmits an entry response to the group management board 2 via the network 21 (S202).
　ノード判定部３１は、Ｓ１０１で参入要求を送信すると、ネットワーク２１を介して制御基板３Ｆ～３Ｉの全てから参入応答を受信したか否かを判定する（Ｓ１０２）。群管理基板２が制御基板３Ｆ～３Ｉの全てから参入応答を受信すると、Ｓ１０２でＹｅｓと判定される。 When the entry request is transmitted in S101, the node determination unit 31 determines whether or not the entry response has been received from all of the control boards 3F to 3I via the network 21 (S102). When the group management board 2 receives the entry response from all of the control boards 3F to 3I, it is determined as Yes in S102.
　Ｓ１０８でＹｅｓと判定されていなければ、Ｓ１０３ではＮｏと判定される。Ｓ１０８の処理については後述する。Ｓ１０３でＮｏと判定されると、ノード判定部３１は、参入応答を送信してきた制御基板のそれぞれに対して、役割を示す信号をネットワーク２１を介して送信する（Ｓ１０５）。以下においては、役割を示す信号のことを「役割信号」ともいう。表１に示す例であれば、ノード判定部３１は、Ｓ１０５において制御基板３Ｆに対してＢＫＭＳＴを示す役割信号を送信する。ノード判定部３１は、Ｓ１０５において制御基板３Ｇに対してＳＬＶを示す役割信号を送信する。 If it is not determined as Yes in S108, it is determined as No in S103. The processing of S108 will be described later. If No is determined in S103, the node determination unit 31 transmits a signal indicating a role to each of the control boards that have transmitted the entry response via the network 21 (S105). In the following, a signal indicating a role is also referred to as a “role signal”. In the example shown in Table 1, the node determination unit 31 transmits a role signal indicating BKMST to the control board 3F in S105. The node determination unit 31 transmits a role signal indicating SLV to the control board 3G in S105.
　Ｓ２０２で群管理基板２に参入応答を送信した制御基板３Ｇでは、役割信号を受信したか否かが判定される（Ｓ２０３）。Ｓ１０５でノード判定部３１が送信した役割信号を制御基板３Ｇが受信すると、Ｓ２０３でＹｅｓと判定される。制御基板３Ｇは、Ｓ２０３で受信した役割信号に応じて自機の役割を設定する（Ｓ２０４）。 The control board 3G that transmitted the entry response to the group management board 2 in S202 determines whether or not the role signal has been received (S203). When the control board 3G receives the role signal transmitted by the node determination unit 31 in S105, it is determined to be Yes in S203. The control board 3G sets the role of its own machine according to the role signal received in S203 (S204).
　群管理基板２では、Ｓ１０２でＹｅｓと判定されると、通常割当制御が行われる（Ｓ１０６）。図５は、通常割当制御の例を示す。群管理基板２では、乗場操作盤４から呼びの登録要求を受信したか否かが判定される（Ｓ３０１）。例えば、Ｓ３０１では、群管理基板２からネットワーク２２に対して、信号の送信を許可するための許可信号が定期的にブロードキャストされる。 In the group management board 2, if Yes is determined in S102, normal allocation control is performed (S106). FIG. 5 shows an example of normal allocation control. The group management board 2 determines whether or not a call registration request has been received from the landing operation panel 4 (S301). For example, in S301, the permission signal for permitting the transmission of the signal is periodically broadcast from the group management board 2 to the network 22.
　図６は、乗場操作盤４の動作例を示す。エレベーターの利用者は、乗場操作盤４に対して特定の入力操作を行うことにより、行先階を入力することができる。乗場操作盤４では、入力操作が行われたか否かが判定される（Ｓ４０１）。利用者が乗場操作盤４から行先階を入力すると、Ｓ４０１でＹｅｓと判定される。Ｓ４０１でＹｅｓと判定されると、乗場操作盤４では、許可信号を受信したか否かが判定される（Ｓ４０２）。 FIG. 6 shows an operation example of the landing operation panel 4. The user of the elevator can input the destination floor by performing a specific input operation on the landing operation panel 4. On the landing operation panel 4, it is determined whether or not an input operation has been performed (S401). When the user inputs the destination floor from the landing operation panel 4, S401 determines Yes. If it is determined to be Yes in S401, the landing operation panel 4 determines whether or not the permission signal has been received (S402).
　Ｓ３０１で群管理基板２が送信した許可信号を乗場操作盤４が受信すると、Ｓ４０２でＹｅｓと判定される。乗場操作盤４は、Ｓ４０２でＹｅｓと判定すると、許可信号を送信してきた群管理基板２に対して、ネットワーク２２を介して呼びの登録要求を送信する（Ｓ４０３）。乗場操作盤４が送信する登録要求には、行先階の情報が含まれる。 When the landing operation panel 4 receives the permission signal transmitted by the group management board 2 in S301, it is determined to be Yes in S402. When the landing operation panel 4 determines Yes in S402, it transmits a call registration request to the group management board 2 that has transmitted the permission signal via the network 22 (S403). The registration request transmitted by the landing operation panel 4 includes information on the destination floor.
　Ｓ４０３で乗場操作盤４が送信した登録要求を群管理基板２が受信すると、Ｓ３０１でＹｅｓと判定される。割当部３２は、Ｓ３０１でＹｅｓと判定すると、Ｓ３０１で受信した登録要求に対する割当かごを決定する（Ｓ３０２）。 When the group management board 2 receives the registration request transmitted by the landing operation panel 4 in S403, it is determined to be Yes in S301. When the allocation unit 32 determines Yes in S301, the allocation unit 32 determines the allocation car for the registration request received in S301 (S302).
　群管理基板２は、Ｓ１０２において参入応答を受信している。このため、群管理基板２では、ネットワーク２１を介して通信可能な制御基板が特定されている。Ｓ３０２において、割当部３２は、ネットワーク２１を介して通信可能な制御基板が制御するかごの中から割当かごを決定する。Ｓ１０２でＹｅｓと判定されていれば、割当部３２は、制御基板３Ｆ～３Ｉが制御する４台のかごの中から割当かごを決定する。 The group management board 2 receives the entry response in S102. Therefore, in the group management board 2, a control board capable of communicating via the network 21 is specified. In S302, the allocation unit 32 determines the allocation car from the cars controlled by the control board that can communicate via the network 21. If it is determined to be Yes in S102, the allocation unit 32 determines the allocation car from the four cars controlled by the control boards 3F to 3I.
　指令部３３は、割当部３２が決定した割当かごを制御する制御基板に対して、ネットワーク２１を介して応答指令を送信する（Ｓ３０３）。例えば、Ｇ号機のかごが割当かごであれば、指令部３３は、ネットワーク２１を介して制御基板３Ｇに応答指令を送信する。Ｓ３０３で送信される応答指令には、行先階の情報が含まれる。また、指令部３３は、割当部３２が割当かごを決定すると、Ｓ３０１で登録要求を送信してきた乗場操作盤４に対して、ネットワーク２２を介して応答信号を送信する（Ｓ３０４）。Ｓ３０４で乗場操作盤４に送信される応答信号には、割当かごの情報が含まれる。 The command unit 33 transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32 (S303). For example, if the car of Unit G is an assigned car, the command unit 33 transmits a response command to the control board 3G via the network 21. The response command transmitted in S303 includes information on the destination floor. Further, when the allocation unit 32 determines the allocation car, the command unit 33 transmits a response signal to the landing operation panel 4 that has transmitted the registration request in S301 via the network 22 (S304). The response signal transmitted to the landing operation panel 4 in S304 includes information on the assigned car.
　乗場操作盤４では、Ｓ４０３で登録要求が送信されると、応答信号を受信したか否かが判定される（Ｓ４０４）。Ｓ３０４で指令部３３が送信した応答信号を乗場操作盤４が受信すると、Ｓ４０４でＹｅｓと判定される。Ｓ４０４でＹｅｓと判定されると、乗場操作盤４では、受信した応答信号に基づいて割当かごの情報が表示器に表示される（Ｓ４０５）。利用者は、乗場操作盤４の表示器を見て、割当かごを知ることができる。 On the landing operation panel 4, when the registration request is transmitted in S403, it is determined whether or not the response signal has been received (S404). When the landing operation panel 4 receives the response signal transmitted by the command unit 33 in S304, it is determined to be Yes in S404. If it is determined to be Yes in S404, the landing operation panel 4 displays the information of the assigned car on the display based on the received response signal (S405). The user can know the assigned car by looking at the display of the landing operation panel 4.
　制御基板３Ｇでは、ネットワーク２１を介して応答指令を受信したか否かが判定される（図４のＳ２０５）。Ｓ３０３で指令部３３が送信した応答指令を制御基板３Ｇが受信すると、Ｓ２０５でＹｅｓと判定される。Ｓ２０５でＹｅｓと判定されると、制御基板３Ｇでは、利用者を行先階に運ぶための応答制御が行われる（Ｓ２０６）。これにより、利用者は、割当かごであるＧ号機のかごに乗って行先階に移動することができる。 On the control board 3G, it is determined whether or not a response command has been received via the network 21 (S205 in FIG. 4). When the control board 3G receives the response command transmitted by the command unit 33 in S303, it is determined as Yes in S205. If it is determined to be Yes in S205, the control board 3G performs response control for transporting the user to the destination floor (S206). As a result, the user can move to the destination floor in the car of Unit G, which is the assigned car.
　また、群管理基板２では、通常割当制御において、乗場釦６から呼びの登録要求を受信したか否かが判定される（図５のＳ３０５）。利用者が乗場釦６を押すと、乗場釦６から群管理基板２に対して、ネットワーク２３を介して呼びの登録要求が送信される。乗場釦６から送信された登録要求を群管理基板２が受信すると、Ｓ３０５でＹｅｓと判定される。割当部３２は、Ｓ３０５でＹｅｓと判定すると、Ｓ３０５で受信した登録要求に対する割当かごを決定する（Ｓ３０６）。 Further, in the group management board 2, it is determined in the normal allocation control whether or not the call registration request is received from the landing button 6 (S305 in FIG. 5). When the user presses the landing button 6, the landing button 6 transmits a call registration request to the group management board 2 via the network 23. When the group management board 2 receives the registration request transmitted from the landing button 6, it is determined as Yes in S305. When the allocation unit 32 determines Yes in S305, the allocation unit 32 determines the allocation car for the registration request received in S305 (S306).
　割当部３２は、Ｓ３０６において、ネットワーク２１を介して通信可能な制御基板が制御するかごの中から割当かごを決定する。Ｓ１０２でＹｅｓと判定されていれば、割当部３２は、制御基板３Ｆ～３Ｉが制御する４台のかごの中から割当かごを決定する。 In S306, the allocation unit 32 determines the allocation car from the cars controlled by the control board that can communicate via the network 21. If it is determined to be Yes in S102, the allocation unit 32 determines the allocation car from the four cars controlled by the control boards 3F to 3I.
　指令部３３は、割当部３２が決定した割当かごを制御する制御基板に対して、ネットワーク２１を介して応答指令を送信する（Ｓ３０７）。例えば、Ｇ号機のかごが割当かごであれば、指令部３３は、ネットワーク２１を介して制御基板３Ｇに応答指令を送信する。Ｓ３０７で送信される応答指令には、行先階の情報は含まれない。また、指令部３３は、割当部３２が割当かごを決定すると、Ｓ３０５で登録要求を送信してきた乗場釦６に対して、ネットワーク２３を介して応答信号を送信する（Ｓ３０８）。 The command unit 33 transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32 (S307). For example, if the car of Unit G is an assigned car, the command unit 33 transmits a response command to the control board 3G via the network 21. The response command transmitted in S307 does not include information on the destination floor. Further, when the allocation unit 32 determines the allocation car, the command unit 33 transmits a response signal to the landing button 6 that has transmitted the registration request in S305 via the network 23 (S308).
　乗場釦６では、Ｓ３０８で送信された応答信号に応じて内部のランプが点灯する。利用者は、点灯した乗場釦６を見て、呼びが登録されたことを知ることができる。 At the landing button 6, the internal lamp lights up according to the response signal transmitted in S308. The user can know that the call has been registered by looking at the lit landing button 6.
　また、Ｓ３０７で指令部３３が送信した応答指令を制御基板３Ｇが受信すると、図４のＳ２０５でＹｅｓと判定される。Ｓ２０５でＹｅｓと判定されると、制御基板３Ｇでは、かごを利用者がいる乗場まで移動させるための応答制御が行われる（Ｓ２０６）。これにより、利用者は、割当かごであるＧ号機のかごに乗ることができる。 Further, when the control board 3G receives the response command transmitted by the command unit 33 in S307, it is determined as Yes in S205 of FIG. If it is determined to be Yes in S205, the control board 3G performs response control for moving the car to the landing where the user is (S206). As a result, the user can get in the car of Unit G, which is the assigned car.
　次に、Ｓ１０２においてＮｏと判定される例について説明する。例えば、Ｆ号機の保守が行われると、Ｆ号機の制御盤の電源が落とされることがある。Ｆ号機の制御盤の電源が落とされると、制御基板３Ｆは図４に示す動作を行うことができない。このため、Ｓ１０１で群管理基板２が参入要求を送信しても、制御基板３Ｆから群管理基板２に対して参入応答は送信されない。Ｓ１０２では、Ｎｏと判定される。 Next, an example in which No is determined in S102 will be described. For example, when the maintenance of the F unit is performed, the power of the control panel of the F unit may be turned off. When the power of the control panel of Unit F is turned off, the control board 3F cannot perform the operation shown in FIG. Therefore, even if the group management board 2 transmits the entry request in S101, the entry response is not transmitted from the control board 3F to the group management board 2. In S102, it is determined as No.
　Ｓ１０２でＮｏと判定されると、離脱検出部３４は、受信した参入応答に基づいて離脱基板を検出する（Ｓ１０７）。離脱基板は、制御基板３Ｆ～３Ｉのうち、ネットワーク２１を介して通信することができない制御基板のことである。Ｆ号機の保守が行われていても、制御基板３Ｇ～３Ｉのそれぞれからは群管理基板２に対して参入応答が送信される。このため、離脱検出部３４は、Ｆ号機の保守が開始されると、Ｓ１０７において制御基板３Ｆを離脱基板と検出する。 If No is determined in S102, the withdrawal detection unit 34 detects the withdrawal board based on the received entry response (S107). The detached board is a control board among the control boards 3F to 3I that cannot communicate via the network 21. Even if the maintenance of Unit F is performed, the entry response is transmitted from each of the control boards 3G to 3I to the group management board 2. Therefore, when the maintenance of the F unit is started, the detachment detection unit 34 detects the control board 3F as the detachment board in S107.
　また、Ｓ１０２でＮｏと判定されると、隔離検出部３５は、受信した参入応答に基づいて隔離基板があるか否かを判定する（Ｓ１０８）。隔離基板は、制御基板３Ｆ～３Ｉのうち、通信機能が停止していないにも関わらずネットワーク２１を介して通信することができない制御基板のことである。一例として、隔離検出部３５は、参入応答を送信してこない制御基板が１台だけであれば、Ｓ１０８でＮｏと判定する。Ｓ１０８でＮｏと判定されると、Ｓ１０３の処理に進む。かかる場合、群管理基板２では、離脱基板を制御対象から除外した上で通常割当制御が行われる。 If No is determined in S102, the isolation detection unit 35 determines whether or not there is an isolation substrate based on the received entry response (S108). The isolation board is a control board among the control boards 3F to 3I, which cannot communicate via the network 21 even though the communication function is not stopped. As an example, the isolation detection unit 35 determines No in S108 if there is only one control board that does not send an entry response. If No is determined in S108, the process proceeds to S103. In such a case, in the group management board 2, the normal allocation control is performed after excluding the detached board from the control target.
　次に、Ｓ１０８においてＹｅｓと判定される例について説明する。Ｆ号機の保守とＨ号機の保守とが同時に行われる例を考える。Ｈ号機の保守が行われると、Ｈ号機の制御盤の電源が落とされることがある。このため、Ｆ号機の保守とＨ号機の保守とが同時に行われると、Ｓ１０１で群管理基板２が参入要求を送信しても、制御基板３Ｆから群管理基板２に対して参入応答は送信されない。同様に、制御基板３Ｈから群管理基板２に対して参入応答は送信されない。離脱検出部３４は、Ｓ１０７において制御基板３Ｆ及び制御基板３Ｈを離脱基板と検出する。 Next, an example in which Yes is determined in S108 will be described. Consider an example in which maintenance of Unit F and maintenance of Unit H are performed at the same time. When the maintenance of Unit H is performed, the power of the control panel of Unit H may be turned off. Therefore, if the maintenance of Unit F and the maintenance of Unit H are performed at the same time, even if the group management board 2 sends an entry request in S101, the entry response is not transmitted from the control board 3F to the group management board 2. .. Similarly, the entry response is not transmitted from the control board 3H to the group management board 2. The detachment detection unit 34 detects the control board 3F and the control substrate 3H as the detachment board in S107.
　制御基板３Ｇは、制御基板３Ｆと制御基板３Ｈとの間に配置されている。このため、制御基板３Ｆと制御基板３Ｈとがネットワーク２１から離脱すると、制御基板３Ｇもネットワーク２１から離脱する。制御基板３Ｇは、Ｓ１０１で群管理基板２が送信した参入要求を受信することができない。このため、制御基板３Ｇは、参入応答を送信しない。離脱検出部３４は、Ｓ１０７において制御基板３Ｇを離脱基板と検出する。なお、制御基板３Ｇは、ネットワーク２１を介して通信することはできないが、その通信機能が停止している訳ではない。 The control board 3G is arranged between the control board 3F and the control board 3H. Therefore, when the control board 3F and the control board 3H are separated from the network 21, the control board 3G is also separated from the network 21. The control board 3G cannot receive the entry request transmitted by the group management board 2 in S101. Therefore, the control board 3G does not transmit the entry response. The detachment detection unit 34 detects the control board 3G as the detachment board in S107. Although the control board 3G cannot communicate via the network 21, its communication function is not stopped.
　隔離検出部３５は、例えば、隣接する基板が共に離脱基板である基板を隔離基板と検出する。Ｆ号機の保守とＨ号機の保守とが同時に行われると、制御基板３Ｇは、離脱基板である制御基板３Ｆと離脱基板である制御基板３Ｈとの間に配置される。このため、隔離検出部３５は、Ｓ１０８において、制御基板３Ｇがネットワーク２１から隔離されたこと、即ち隔離基板が存在することを検出する。 The isolation detection unit 35 detects, for example, a substrate whose adjacent substrates are both detached substrates as an isolation substrate. When the maintenance of the F unit and the maintenance of the H unit are performed at the same time, the control board 3G is arranged between the control board 3F which is a detachment board and the control board 3H which is a detachment board. Therefore, the isolation detection unit 35 detects in S108 that the control board 3G is isolated from the network 21, that is, the existence of the isolation board.
　Ｓ１０８でＹｅｓと判定されると、ノード判定部３１は、制御基板３Ｆ～３Ｉのうち参入応答を送信してきた制御基板のそれぞれに対して、ネットワーク２１を介して役割信号を送信する（Ｓ１０９）。また、Ｓ１０８でＹｅｓと判定されると、群管理基板２では、特別割当制御が開始される（Ｓ１１０）。 If it is determined to be Yes in S108, the node determination unit 31 transmits a role signal via the network 21 to each of the control boards 3F to 3I that have transmitted the entry response (S109). If Yes is determined in S108, the group management board 2 starts special allocation control (S110).
　図７は、特別割当制御の例を示す。群管理基板２では、乗場操作盤４ＦＧから呼びの登録要求を受信したか否かが判定される（Ｓ５０１）。例えば、Ｓ５０１では、群管理基板２からネットワーク２２Ｆに対して、信号の送信を許可するための許可信号が定期的にブロードキャストされる。また、群管理基板２では、乗場操作盤４ＨＩから呼びの登録要求を受信したか否かが判定される（Ｓ５０２）。例えば、Ｓ５０２では、群管理基板２からネットワーク２２Ｈに対して、信号の送信を許可するための許可信号が定期的にブロードキャストされる。乗場操作盤４ＦＧ及び乗場操作盤４ＨＩのそれぞれでは、図６に示す動作が行われる。 FIG. 7 shows an example of special allocation control. The group management board 2 determines whether or not a call registration request has been received from the landing operation panel 4FG (S501). For example, in S501, the permission signal for permitting the transmission of the signal is periodically broadcast from the group management board 2 to the network 22F. Further, the group management board 2 determines whether or not a call registration request has been received from the landing operation panel 4HI (S502). For example, in S502, the permission signal for permitting the transmission of the signal is periodically broadcast from the group management board 2 to the network 22H. The operations shown in FIG. 6 are performed on each of the landing operation panel 4FG and the landing operation panel 4HI.
　Ｓ４０３で乗場操作盤４ＨＩが送信した登録要求を群管理基板２が受信すると、Ｓ５０２でＹｅｓと判定される。Ｓ５０３からＳ５０５に示す動作は、Ｓ３０２からＳ３０４に示す動作と同様である。割当部３２は、Ｓ５０２でＹｅｓと判定すると、ネットワーク２１を介して通信可能な制御基板が制御するかごの中から割当かごを決定する（Ｓ５０３）。 When the group management board 2 receives the registration request transmitted by the landing operation panel 4HI in S403, it is determined to be Yes in S502. The operations shown in S503 to S505 are the same as the operations shown in S302 to S304. When the allocation unit 32 determines Yes in S502, the allocation unit 32 determines the allocation car from the cars controlled by the control board capable of communicating via the network 21 (S503).
　指令部３３は、割当部３２が決定した割当かごを制御する制御基板に対して、ネットワーク２１を介して応答指令を送信する（Ｓ５０４）。また、指令部３３は、割当部３２が割当かごを決定すると、Ｓ５０２で登録要求を送信してきた乗場操作盤４ＨＩに対して、ネットワーク２２Ｈを介して応答信号を送信する（Ｓ５０５）。Ｓ５０５で乗場操作盤４ＨＩに送信される応答信号には、割当かごの情報が含まれる。 The command unit 33 transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32 (S504). Further, when the allocation unit 32 determines the allocation car, the command unit 33 transmits a response signal to the landing operation panel 4HI that has transmitted the registration request in S502 via the network 22H (S505). The response signal transmitted to the landing operation panel 4HI in S505 includes information on the assigned car.
　一方、Ｓ４０３で乗場操作盤４ＦＧが送信した登録要求を群管理基板２が受信すると、Ｓ５０１でＹｅｓと判定される。割当部３２は、Ｓ５０１でＹｅｓと判定されても、登録要求に対する割当かごの決定を行わない。Ｓ５０１でＹｅｓと判定されると、転送部３６は、乗場操作盤４ＦＧからの登録要求を、ネットワーク２４を介して隔離基板、即ち制御基板３Ｇに転送する（Ｓ５０６）。Ｓ５０６では、転送部３６は、Ｓ５０１で受信した登録要求をそのまま制御基板３Ｇに送る。 On the other hand, when the group management board 2 receives the registration request transmitted by the landing operation panel 4FG in S403, it is determined as Yes in S501. The allocation unit 32 does not determine the allocation car for the registration request even if it is determined to be Yes in S501. If it is determined to be Yes in S501, the transfer unit 36 transfers the registration request from the landing operation panel 4FG to the isolation board, that is, the control board 3G via the network 24 (S506). In S506, the transfer unit 36 sends the registration request received in S501 to the control board 3G as it is.
　例えば、制御基板３Ｇでは、乗場操作盤４ＦＧからの登録要求をネットワーク２４を介して群管理基板２から受信したか否かが判定される（Ｓ２０７）。Ｓ５０６で転送部３６が転送した登録要求を制御基板３Ｇが受信すると、Ｓ２０７でＹｅｓと判定される。Ｓ２０７でＹｅｓと判定されると、制御基板３Ｇは、受信した登録要求に対する応答信号を、ネットワーク２４を介して群管理基板２に送信する（Ｓ２０８）。Ｓ２０８で送信される応答信号には、登録要求に応答する号機の情報が含まれる。また、Ｓ２０７でＹｅｓと判定されると、制御基板３Ｇでは、利用者を行先階に運ぶための応答制御が行われる（Ｓ２０９）。 For example, in the control board 3G, it is determined whether or not the registration request from the landing operation panel 4FG is received from the group management board 2 via the network 24 (S207). When the control board 3G receives the registration request transferred by the transfer unit 36 in S506, it is determined to be Yes in S207. If it is determined to be Yes in S207, the control board 3G transmits a response signal to the received registration request to the group management board 2 via the network 24 (S208). The response signal transmitted in S208 includes information on the unit that responds to the registration request. Further, if it is determined to be Yes in S207, the control board 3G performs response control for transporting the user to the destination floor (S209).
　転送部３６は、Ｓ５０６で登録要求を転送すると、登録要求の転送先である制御基板３Ｇから、ネットワーク２４を介して応答信号を受信したか否かを判定する（Ｓ５０７）。Ｓ２０８で制御基板３Ｇが送信した応答信号を群管理基板２が受信すると、Ｓ５０７でＹｅｓと判定される。転送部３６は、Ｓ５０７でＹｅｓと判定すると、制御基板３Ｇからの応答信号を、ネットワーク２２Ｆを介して乗場操作盤４ＦＧに転送する（Ｓ５０８）。Ｓ５０８では、転送部３６は、Ｓ５０７で受信した応答信号をそのまま乗場操作盤４ＦＧに送る。 When the registration request is transferred in S506, the transfer unit 36 determines whether or not a response signal has been received from the control board 3G, which is the transfer destination of the registration request, via the network 24 (S507). When the group management board 2 receives the response signal transmitted by the control board 3G in S208, it is determined to be Yes in S507. When the transfer unit 36 determines Yes in S507, the transfer unit 36 transfers the response signal from the control board 3G to the landing operation panel 4FG via the network 22F (S508). In S508, the transfer unit 36 sends the response signal received in S507 as it is to the landing operation panel 4FG.
　図８は、特別割当制御の他の例を示す。図７は、乗場操作盤４から登録要求を受信した時の群管理基板２の動作を示す。これに対し、図８は、乗場釦６から登録要求を受信した時の群管理基板２の動作を示す。 FIG. 8 shows another example of special allocation control. FIG. 7 shows the operation of the group management board 2 when a registration request is received from the landing operation panel 4. On the other hand, FIG. 8 shows the operation of the group management board 2 when the registration request is received from the landing button 6.
　群管理基板２では、乗場釦６ＦＧから呼びの登録要求を受信したか否かが判定される（Ｓ６０１）。また、群管理基板２では、乗場釦６ＨＩから呼びの登録要求を受信したか否かが判定される（Ｓ６０２）。利用者が乗場釦６ＨＩを押すと、乗場釦６ＨＩから群管理基板２に対して、ネットワーク２３Ｈを介して呼びの登録要求が送信される。乗場釦６ＨＩから送信された登録要求を群管理基板２が受信すると、Ｓ６０２でＹｅｓと判定される。 On the group management board 2, it is determined whether or not a call registration request has been received from the landing button 6FG (S601). Further, the group management board 2 determines whether or not a call registration request has been received from the landing button 6HI (S602). When the user presses the landing button 6HI, the landing button 6HI transmits a call registration request to the group management board 2 via the network 23H. When the group management board 2 receives the registration request transmitted from the landing button 6HI, it is determined as Yes in S602.
　Ｓ６０３からＳ６０５に示す動作は、Ｓ３０６からＳ３０８に示す動作と同様である。割当部３２は、Ｓ６０２でＹｅｓと判定すると、ネットワーク２１を介して通信可能な制御基板が制御するかごの中から割当かごを決定する（Ｓ６０３）。指令部３３は、割当部３２が決定した割当かごを制御する制御基板に対して、ネットワーク２１を介して応答指令を送信する（Ｓ６０４）。また、指令部３３は、割当部３２が割当かごを決定すると、Ｓ６０２で登録要求を送信してきた乗場釦６ＨＩに対して、ネットワーク２３Ｈを介して応答信号を送信する（Ｓ６０５）。 The operations shown in S603 to S605 are the same as the operations shown in S306 to S308. When the allocation unit 32 determines Yes in S602, the allocation unit 32 determines the allocation car from the cars controlled by the control board capable of communicating via the network 21 (S603). The command unit 33 transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32 (S604). Further, when the allocation unit 32 determines the allocation car, the command unit 33 transmits a response signal to the landing button 6HI that has transmitted the registration request in S602 via the network 23H (S605).
　利用者が乗場釦６ＦＧを押すと、Ｓ６０１でＹｅｓと判定される。割当部３２は、Ｓ６０１でＹｅｓと判定されても、登録要求に対する割当かごの決定を行わない。Ｓ６０１でＹｅｓと判定されると、転送部３６は、乗場釦６ＦＧからの登録要求を、ネットワーク２４を介して隔離基板、即ち制御基板３Ｇに転送する（Ｓ６０６）。Ｓ６０６では、転送部３６は、Ｓ６０１で受信した登録要求をそのまま制御基板３Ｇに送る。 When the user presses the landing button 6FG, S601 determines Yes. Even if the allocation unit 32 determines Yes in S601, the allocation unit 32 does not determine the allocation car for the registration request. If it is determined to be Yes in S601, the transfer unit 36 transfers the registration request from the landing button 6FG to the isolation board, that is, the control board 3G via the network 24 (S606). In S606, the transfer unit 36 sends the registration request received in S601 to the control board 3G as it is.
　例えば、制御基板３Ｇでは、乗場釦６ＦＧからの登録要求をネットワーク２４を介して群管理基板２から受信したか否かが判定される（Ｓ２１０）。Ｓ６０６で転送部３６が転送した登録要求を制御基板３Ｇが受信すると、Ｓ２１０でＹｅｓと判定される。Ｓ２１０でＹｅｓと判定されると、制御基板３Ｇは、受信した登録要求に対する応答信号を、ネットワーク２４を介して群管理基板２に送信する（Ｓ２１１）。また、Ｓ２１０でＹｅｓと判定されると、制御基板３Ｇでは、かごを利用者がいる乗場まで移動させるための応答制御が行われる（Ｓ２１２）。 For example, in the control board 3G, it is determined whether or not the registration request from the landing button 6FG is received from the group management board 2 via the network 24 (S210). When the control board 3G receives the registration request transferred by the transfer unit 36 in S606, it is determined as Yes in S210. If it is determined to be Yes in S210, the control board 3G transmits a response signal to the received registration request to the group management board 2 via the network 24 (S211). Further, if it is determined to be Yes in S210, the control board 3G performs response control for moving the car to the landing where the user is (S212).
　転送部３６は、Ｓ６０６で登録要求を転送すると、登録要求の転送先である制御基板３Ｇから、ネットワーク２４を介して応答信号を受信したか否かを判定する（Ｓ６０７）。Ｓ２１１で制御基板３Ｇが送信した応答信号を群管理基板２が受信すると、Ｓ６０７でＹｅｓと判定される。転送部３６は、Ｓ６０７でＹｅｓと判定すると、制御基板３Ｇからの応答信号を、ネットワーク２３Ｆを介して乗場釦６ＦＧに転送する（Ｓ６０８）。Ｓ６０８では、転送部３６は、Ｓ６０７で受信した応答信号をそのまま乗場釦６ＦＧに送る。 When the registration request is transferred in S606, the transfer unit 36 determines whether or not a response signal has been received from the control board 3G, which is the transfer destination of the registration request, via the network 24 (S607). When the group management board 2 receives the response signal transmitted by the control board 3G in S211, it is determined to be Yes in S607. When the transfer unit 36 determines Yes in S607, the transfer unit 36 transfers the response signal from the control board 3G to the landing button 6FG via the network 23F (S608). In S608, the transfer unit 36 sends the response signal received in S607 to the landing button 6FG as it is.
　次に、Ｓ１０８でＹｅｓと判定された後に、Ｓ１０８でＮｏ或いはＳ１０２でＹｅｓと判定される例について説明する。上述したように、Ｆ号機の保守とＨ号機の保守とが同時に行われると、Ｓ１０８でＹｅｓと判定される。その後、Ｆ号機の保守とＨ号機の保守とが終了すると、制御基板３Ｆ及び制御基板３Ｈにおいて図４に示す動作が開始される。また、制御基板３Ｇでは、ネットワーク２１を介した群管理基板２との通信が可能になる。 Next, an example will be described in which, after being determined as Yes in S108, it is determined as No in S108 or Yes in S102. As described above, when the maintenance of the F unit and the maintenance of the H unit are performed at the same time, it is determined as Yes in S108. After that, when the maintenance of the F unit and the maintenance of the H unit are completed, the operations shown in FIG. 4 are started on the control board 3F and the control board 3H. Further, the control board 3G enables communication with the group management board 2 via the network 21.
　復帰検出部３７は、Ｓ１０３において、隔離基板がネットワーク２１に復帰したか否かを判定する。例えば、復帰検出部３７は、Ｓ１０８で隔離基板と検出された制御基板から参入応答を受信すると、その制御基板がネットワーク２１に復帰したことを検出する（Ｓ１０３のＹｅｓ）。Ｓ１０３でＹｅｓと判定されると、転送部３６は、Ｓ５０６及びＳ６０６の登録要求の転送を停止する（Ｓ１０４）。これにより、Ｓ１０６において、通常割当制御が再開される。 The return detection unit 37 determines in S103 whether or not the isolation board has returned to the network 21. For example, when the return detection unit 37 receives an entry response from the control board detected as the isolation board in S108, it detects that the control board has returned to the network 21 (Yes in S103). If it is determined to be Yes in S103, the transfer unit 36 stops the transfer of the registration requests of S506 and S606 (S104). As a result, in S106, the normal allocation control is restarted.
　本実施の形態に示す例では、例えば、制御基板３Ｇがネットワーク２１から隔離されても、乗場操作盤４ＦＧからの登録要求が群管理基板２から制御基板３Ｇに転送される。このため、制御基板３Ｇがネットワーク２１から隔離されても、運行効率が大きく悪化することを防止できる。 In the example shown in this embodiment, for example, even if the control board 3G is isolated from the network 21, the registration request from the landing operation panel 4FG is transferred from the group management board 2 to the control board 3G. Therefore, even if the control board 3G is isolated from the network 21, it is possible to prevent the operation efficiency from being significantly deteriorated.
　また、制御基板３Ｇがネットワーク２１に復帰すると、登録要求の転送が停止される。このため、隔離基板のネットワーク２１への復帰に合わせて、通常割当制御を即座に再開できる。 Further, when the control board 3G returns to the network 21, the transfer of the registration request is stopped. Therefore, the normal allocation control can be resumed immediately when the isolated substrate is returned to the network 21.
　転送部３６による登録要求の転送は、ネットワーク２４を介して行われる。ネットワーク２４は、基本的に、共通信号の伝送に用いられるネットワークである。例えば、共通基板８は、地震感知器からの地震信号を受信すると、その受信した地震信号をネットワーク２４を介して群管理基板２に送信する。この時、共通基板８からネットワーク２４に対して地震信号がブロードキャストされても良い。他の例として、共通基板８は、火災感知器からの火災信号を受信すると、その受信した火災信号をネットワーク２４を介して群管理基板２に送信する。この時、共通基板８からネットワーク２４に対して火災信号がブロードキャストされても良い。 The transfer of the registration request by the transfer unit 36 is performed via the network 24. The network 24 is basically a network used for transmitting a common signal. For example, when the common board 8 receives the seismic signal from the seismic detector, the common board 8 transmits the received seismic signal to the group management board 2 via the network 24. At this time, the seismic signal may be broadcast from the common board 8 to the network 24. As another example, when the common board 8 receives a fire signal from the fire detector, the common board 8 transmits the received fire signal to the group management board 2 via the network 24. At this time, a fire signal may be broadcast from the common board 8 to the network 24.
　図９は、実施の形態１におけるエレベーターシステム１の他の動作例を示すフローチャートである。図９は、役割がＭＳＴに設定されていない制御基板の他の動作を示す。以下に、図９を参照し、隔離検出部３５が隔離基板を検出する他の例について説明する。図９のＳ２０１からＳ２１２に示す処理は、図４のＳ２０１からＳ２１２に示す処理と同様である。 FIG. 9 is a flowchart showing another operation example of the elevator system 1 according to the first embodiment. FIG. 9 shows other operations of the control board whose role is not set to MST. Hereinafter, another example in which the isolation detection unit 35 detects the isolation substrate will be described with reference to FIG. The processing shown in S201 to S212 in FIG. 9 is the same as the processing shown in S201 to S212 in FIG.
　上述したように、群管理基板２から制御基板３Ｆ～３Ｉに対して、ネットワーク２１を介して定期的に参入要求が送信される。例えば、制御基板３Ｇでは、参入要求を受信したか否かが判定される（Ｓ２０１）。制御基板３Ｇは、Ｓ２０１でＹｅｓと判定すると、上述したＳ２０２からＳ２０６に示す処理を行う。 As described above, the group management board 2 periodically sends an entry request to the control boards 3F to 3I via the network 21. For example, in the control board 3G, it is determined whether or not the entry request has been received (S201). When the control board 3G determines Yes in S201, the control board 3G performs the processes shown in S202 to S206 described above.
　Ｓ２０１でＮｏと判定されると、制御基板３Ｇでは、参入要求を受信することなく時間Ｔが経過したか否かを判定する（Ｓ２１３）。時間Ｔは、群管理基板２が参入要求を送信する周期より長い時間である。制御基板３Ｇは、群管理基板２からの参入要求を時間Ｔが経過するまで受信しなければ、ネットワーク２４を介して隔離信号を群管理基板２に送信する（Ｓ２１４）。Ｓ２１４では、制御基板３Ｇからネットワーク２４に対して隔離信号がブロードキャストされても良い。 If No is determined in S201, the control board 3G determines whether or not the time T has elapsed without receiving the entry request (S213). The time T is a time longer than the cycle in which the group management board 2 transmits the entry request. If the control board 3G does not receive the entry request from the group management board 2 until the time T elapses, the control board 3G transmits an isolation signal to the group management board 2 via the network 24 (S214). In S214, the isolation signal may be broadcast from the control board 3G to the network 24.
　隔離検出部３５は、Ｓ２１４で送信された隔離信号を受信すると、隔離信号を送信してきた制御基板がネットワーク２１から隔離されたことを検出する。隔離検出部３５は、隣接する基板が共に離脱基板である基板から隔離信号を受信した場合に、その隔離信号を送信してきた制御基板がネットワーク２１から隔離されたことを検出しても良い。 When the isolation detection unit 35 receives the isolation signal transmitted in S214, it detects that the control board that has transmitted the isolation signal has been isolated from the network 21. The isolation detection unit 35 may detect that the control board that has transmitted the isolation signal has been isolated from the network 21 when the isolation signal is received from the boards that are both detached boards.
　本実施の形態において、符号３１～３７に示す各部は、群管理基板２が有する機能を示す。図１０は、群管理基板２のハードウェア資源の例を示す図である。群管理基板２は、ハードウェア資源として、例えばプロセッサ４１とメモリ４２とを含む処理回路４０を備える。群管理基板２は、メモリ４２に記憶されたプログラムをプロセッサ４１によって実行することにより、符号３１～３７に示す各部の機能を実現する。 In the present embodiment, each part indicated by reference numerals 31 to 37 indicates a function possessed by the group management board 2.

As the memory 42, a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD may be adopted. The semiconductor memory that can be adopted includes RAM, ROM, flash memory, EPROM, EEPROM, and the like.
　図１１は、群管理基板２のハードウェア資源の他の例を示す図である。図１１に示す例では、群管理基板２は、例えばプロセッサ４１、メモリ４２、及び専用ハードウェア４３を含む処理回路４０を備える。図１１は、群管理基板２が有する機能の一部を専用ハードウェア４３によって実現する例を示す。群管理基板２が有する機能の全部を専用ハードウェア４３によって実現しても良い。専用ハードウェア４３として、単一回路、複合回路、プログラム化したプロセッサ、並列プログラム化したプロセッサ、ＡＳＩＣ、ＦＰＧＡ、又はこれらの組み合わせを採用できる。 FIG. 11 is a diagram showing another example of the hardware resources of the group management board 2. In the example shown in FIG. 11, the group management board 2 includes, for example, a processing circuit 40 including a processor 41, a memory 42, and dedicated hardware 43. FIG. 11 shows an example in which a part of the functions of the group management board 2 is realized by the dedicated hardware 43. All the functions of the group management board 2 may be realized by the dedicated hardware 43. As the dedicated hardware 43, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof can be adopted.

The control board 3G may include a processing circuit including a processor, a memory, and dedicated hardware as hardware resources.
