The first control board is included in a plurality of control boards when the isolation detection means for detecting that the first control board is isolated from the first network and the isolation detection means for detecting that the first control board is isolated. In the isolation determination means for determining whether or not there is another control board isolated from the first network, and when the isolation determination means determines that there is no other control board, registration requests from a plurality of landing devices are received. When one car is made to respond and the isolation determination means determines that another control board is present, the first car is made to respond to the registration request from the first landing device and the first car is not made to respond to the registration request from the second landing device.

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、かご２Ｆ～２Ｉ、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７ＦＧ、及びリレー基板７ＨＩ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２２、並びにネットワーク２３ＦＧ及び２３ＨＩを備える。 The elevator system 1 includes a car 2F to 2I, a control board 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 7FG, and a relay board 7HI. Further, the elevator system 1 includes a network 21, a network 22, and networks 23FG and 23HI.
　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２Ｆ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２Ｇ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 control board 3F controls the operation of Unit F. For example, the car 2F 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 2G 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２Ｈ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２Ｉ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 2H 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 2I 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、システム全体の運行を管理する群管理機能を有する。群管理機能は、制御基板３Ｆ～３Ｉのうちの１つによって実行されれば良い。このため、制御基板３Ｆ～３Ｉ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 a group management function for managing the operation of the entire system. The group management function may be executed by one of the control boards 3F to 3I. Therefore, the priority for executing the group management function is set in advance for 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、制御基板３Ｆ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３Ｈ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。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 priority of the control board 3F is the highest. The role of the substrate with the highest priority is the master (MST). The control board 3H has the second highest priority. The role of the board with the second highest priority is the backup master (BKMST). Other control boards have the lowest priority. The role of the board with the lowest priority is the slave (SLV).
　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、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、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、制御基板３Ｆが群管理機能を実行する。制御基板３Ｆが群管理機能を実行できなくなると、制御基板３Ｈの役割がＢＫＭＳＴからＭＳＴに繰り上がり、制御基板３Ｈが群管理機能を担う。 Each of the control boards 3F to 3I is provided with control parameters for enabling and disabling the group management function. For example, in each of 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 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 control board 3F basically executes the group management function. When the control board 3F cannot execute the group management function, the role of the control board 3H shifts from BKMST to MST, and the control board 3H takes charge of the group management function.
　ネットワーク２１は、制御基板３Ｆ～３Ｉ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と制御基板３Ｆとの間に配置される。 The network 21 connects the control boards 3F to 3I in a ring-type topology. The network 21 may include 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 3G is arranged between the control board 3F and the control board 3H with respect to the network 21. The control board 3H is arranged between the control board 3G and the control board 3I. The control board 3I is arranged between the control board 3H and the control board 3F.

　以下に、図３から図７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７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に設定された制御基板の動作例を示す。例えば、図３は、制御基板３Ｆの動作を示す。 The functions of the elevator system 1 will be described in detail below with reference to FIGS. 3 to 7. 3 to 7 are flowcharts showing an operation example of the elevator system 1 according to the first embodiment. FIG. 3 shows an operation example of the control board whose role is set to MST. For example, FIG. 3 shows the operation of the control board 3F.
　ノード判定部３１Ｆは、他の制御基板、即ち制御基板３Ｇ～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他の制御基板への問い合わせである。例えば、Ｓ１０１では、制御基板３Ｆ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、制御基板３Ｆにおいて定期的に行われる。 The node determination unit 31F transmits an entry request to another control board, that is, control boards 3G to 3I, via the network 21 (S101). The entry request is an inquiry to other control boards necessary for performing group management. For example, in S101, an entry request is broadcast from the control board 3F to the network 21. The processing of S101 is periodically performed on the control board 3F.
　図４は、役割がＢＫＭＳＴに設定された制御基板の動作例を示す。例えば、図４は制御基板３Ｈの動作を示す。制御基板３Ｈでは、ノード判定部３１Ｈが、他の制御基板からネットワーク２１を介して参入要求を受信したか否かを判定する（Ｓ２０１）。Ｓ１０１でノード判定部３１Ｆが送信した参入要求を制御基板３Ｈが受信すると、Ｓ２０１でＹｅｓと判定される。ノード判定部３１Ｈは、Ｓ２０１でＹｅｓと判定すると、制御基板３Ｆ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 set to BKMST. For example, FIG. 4 shows the operation of the control board 3H. In the control board 3H, the node determination unit 31H determines whether or not an entry request has been received from another control board via the network 21 (S201). When the control board 3H receives the entry request transmitted by the node determination unit 31F in S101, it is determined to be Yes in S201. When the node determination unit 31H determines Yes in S201, the node determination unit 31H transmits an entry response to the control board 3F via the network 21 (S202).
　図５は、役割がＳＬＶに設定された制御基板の動作例を示す。例えば、図５は制御基板３Ｇの動作を示す。制御基板３Ｇでは、ノード判定部３１Ｇが、他の制御基板からネットワーク２１を介して参入要求を受信したか否かを判定する（Ｓ３０１）。Ｓ１０１でノード判定部３１Ｆが送信した参入要求を制御基板３Ｇが受信すると、Ｓ３０１でＹｅｓと判定される。ノード判定部３１Ｇは、Ｓ３０１でＹｅｓと判定すると、制御基板３Ｆに対してネットワーク２１を介して参入応答を送信する（Ｓ３０２）。 FIG. 5 shows an operation example of the control board whose role is set to SLV. For example, FIG. 5 shows the operation of the control board 3G. In the control board 3G, the node determination unit 31G determines whether or not an entry request has been received from another control board via the network 21 (S301). When the control board 3G receives the entry request transmitted by the node determination unit 31F in S101, it is determined to be Yes in S301. When the node determination unit 31G determines Yes in S301, the node determination unit 31G transmits an entry response to the control board 3F via the network 21 (S302).
　ノード判定部３１Ｆは、Ｓ１０１で参入要求を送信すると、ネットワーク２１を介して他の全ての制御基板、即ち制御基板３Ｇ～３Ｉから参入応答を受信したか否かを判定する（Ｓ１０２）。制御基板３Ｆが制御基板３Ｇ～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 31F determines whether or not an entry response has been received from all other control boards, that is, control boards 3G to 3I via the network 21 (S102). When the control board 3F receives the entry response from all of the control boards 3G to 3I, it is determined as Yes in S102.
　ノード判定部３１Ｆは、Ｓ１０２でＹｅｓと判定すると、制御基板３Ｇ～３Ｉ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（Ｓ１０３）。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３１Ｆは、Ｓ１０３において制御基板３Ｈに対してＢＫＭＳＴを示す役割信号を送信する。ノード判定部３１Ｆは、制御基板３Ｇ及び制御基板３Ｉに対してＳＬＶを示す役割信号を送信する。 When the node determination unit 31F determines Yes in S102, it transmits a signal indicating a role to each of the control boards 3G to 3I via the network 21 (S103). 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 31F transmits a role signal indicating BKMST to the control board 3H in S103. The node determination unit 31F transmits a role signal indicating SLV to the control board 3G and the control board 3I.
　Ｓ２０２で制御基板３Ｆに参入応答を送信した制御基板３Ｈでは、ノード判定部３１Ｈが、役割信号を受信したか否かを判定する（Ｓ２０３）。Ｓ１０３でノード判定部３１Ｆが送信した役割信号を制御基板３Ｈが受信すると、Ｓ２０３でＹｅｓと判定される。ノード判定部３１Ｈ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）。 In the control board 3H in which the entry response is transmitted to the control board 3F in S202, the node determination unit 31H determines whether or not the role signal has been received (S203). When the control board 3H receives the role signal transmitted by the node determination unit 31F in S103, it is determined to be Yes in S203. The node determination unit 31H sets the role of the own machine according to the role signal received in S203 (S204).
　同様に、Ｓ３０２で制御基板３Ｆに参入応答を送信した制御基板３Ｇでは、ノード判定部３１Ｇが、役割信号を受信したか否かを判定する（Ｓ３０３）。Ｓ１０３でノード判定部３１Ｆが送信した役割信号を制御基板３Ｇが受信すると、Ｓ３０３でＹｅｓと判定される。ノード判定部３１Ｇは、Ｓ３０３で受信した役割信号に応じて自機の役割を設定する（Ｓ３０４）。 Similarly, in the control board 3G in which the entry response is transmitted to the control board 3F in S302, the node determination unit 31G determines whether or not the role signal has been received (S303). When the control board 3G receives the role signal transmitted by the node determination unit 31F in S103, it is determined to be Yes in S303. The node determination unit 31G sets the role of the own machine according to the role signal received in S303 (S304).
　制御基板３Ｆでは、Ｓ１０２でＹｅｓと判定されると、通常割当制御が行われる（Ｓ１０４）。 On the control board 3F, if it is determined to be Yes in S102, normal allocation control is performed (S104).
　図６は、通常割当制御の例を示す。制御基板３Ｆ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（Ｓ４０１）。例えば、Ｓ４０１では、制御基板３Ｆ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。 FIG. 6 shows an example of normal allocation control. On the control board 3F, it is determined whether or not a call registration request has been received from the landing operation panel 4 (S401). For example, in S401, a permission signal for permitting signal transmission is periodically broadcast from the control board 3F to the network 22.
　図７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（Ｓ５０１）。利用者が乗場操作盤４から行先階を入力すると、Ｓ５０１でＹｅｓと判定される。Ｓ５０１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（Ｓ５０２）。 FIG. 7 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 (S501). When the user inputs the destination floor from the landing operation panel 4, it is determined as Yes in S501. If it is determined to be Yes in S501, the landing operation panel 4 determines whether or not the permission signal has been received (S502).
　Ｓ４０１で制御基板３Ｆが送信した許可信号を乗場操作盤４が受信すると、Ｓ５０２でＹｅｓと判定される。乗場操作盤４は、Ｓ５０２でＹｅｓと判定すると、許可信号を送信してきた制御基板３Ｆ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（Ｓ５０３）。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 control board 3F in S401, it is determined to be Yes in S502. When the landing operation panel 4 determines Yes in S502, it transmits a call registration request to the control board 3F that has transmitted the permission signal via the network 22 (S503). The registration request transmitted by the landing operation panel 4 includes information on the destination floor.
　Ｓ５０３で乗場操作盤４が送信した登録要求を制御基板３Ｆが受信すると、Ｓ４０１でＹｅｓと判定される。割当部３２Ｆは、Ｓ４０１でＹｅｓと判定すると、Ｓ４０１で受信した登録要求に対する割当かごを決定する（Ｓ４０２）。 When the control board 3F receives the registration request transmitted by the landing operation panel 4 in S503, it is determined as Yes in S401. When the allocation unit 32F determines Yes in S401, it determines the allocation car for the registration request received in S401 (S402).
　制御基板３Ｆは、Ｓ１０２において参入応答を受信している。このため、制御基板３Ｆ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。Ｓ４０２において、割当部３２Ｆは、かご２Ｆ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と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３２Ｆは、かご２Ｆ～２Ｉの中から割当かごを決定する。 The control board 3F receives the entry response in S102. Therefore, on the control board 3F, a control board capable of communicating via the network 21 is specified. In S402, the allocation unit 32F determines the allocation car from the cars controlled by the control board that can communicate with the car 2F via the network 21. If it is determined to be Yes in S102, the allocation unit 32F determines the allocation car from the cars 2F to 2I.
　指令部３３Ｆは、割当部３２Ｆ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（Ｓ４０３）。例えば、Ｇ号機のかご２Ｇが割当かごであれば、指令部３３Ｆ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。Ｓ４０３で送信される応答指令には、行先階の情報が含まれる。なお、Ｓ４０２で割当部３２Ｆがかご２Ｆを割当かごに決定すると、Ｓ４０３では、運行制御部３４Ｆが、利用者を行先階に運ぶための応答制御を行う。この場合、Ｓ４０３において応答指令の送信は行われない。 The command unit 33F transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32F (S403). For example, if the car 2G of Unit G is an assigned car, the command unit 33F transmits a response command to the control board 3G via the network 21. The response command transmitted in S403 includes information on the destination floor. When the allocation unit 32F determines the car 2F as the allocation car in S402, the operation control unit 34F performs response control for transporting the user to the destination floor in S403. In this case, the response command is not transmitted in S403.
　また、指令部３３Ｆは、割当部３２Ｆが割当かごを決定すると、Ｓ４０１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（Ｓ４０４）。Ｓ４０４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。 Further, when the allocation unit 32F determines the allocation car, the command unit 33F transmits a response signal to the landing operation panel 4 that has transmitted the registration request in S401 via the network 22 (S404). The response signal transmitted to the landing operation panel 4 in S404 includes information on the assigned car.
　乗場操作盤４では、Ｓ５０３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（Ｓ５０４）。Ｓ４０４で指令部３３Ｆが送信した応答信号を乗場操作盤４が受信すると、Ｓ５０４でＹｅｓと判定される。Ｓ５０４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（Ｓ５０５）。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 S503, it is determined whether or not the response signal has been received (S504). When the landing operation panel 4 receives the response signal transmitted by the command unit 33F in S404, it is determined to be Yes in S504. If Yes is determined in S504, the landing operation panel 4 displays the information of the assigned car on the display based on the received response signal (S505). The user can know the assigned car by looking at the display of the landing operation panel 4.
　制御基板３Ｈ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）。Ｓ４０３で指令部３３Ｆが送信した応答指令を制御基板３Ｈ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、運行制御部３４Ｈは、利用者を行先階に運ぶための応答制御を行う（Ｓ２０６）。これにより、利用者は、割当かごであるかご２Ｈに乗って行先階に移動することができる。 The control board 3H determines whether or not a response command has been received via the network 21 (S205 in FIG. 4). When the control board 3H receives the response command transmitted by the command unit 33F in S403, it is determined to be Yes in S205. If it is determined to be Yes in S205, the operation control unit 34H 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 2H, which is the allocation car.
　同様に、例えば、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５のＳ３０５）。Ｓ４０３で指令部３３Ｆが送信した応答指令を制御基板３Ｇが受信すると、Ｓ３０５でＹｅｓと判定される。Ｓ３０５でＹｅｓと判定されると、運行制御部３４Ｇは、利用者を行先階に運ぶための応答制御を行う（Ｓ３０６）。これにより、利用者は、割当かごであるかご２Ｇに乗って行先階に移動することができる。 Similarly, for example, in the control board 3G, it is determined whether or not a response command has been received via the network 21 (S305 in FIG. 5). When the control board 3G receives the response command transmitted by the command unit 33F in S403, it is determined as Yes in S305. If it is determined to be Yes in S305, the operation control unit 34G performs response control for transporting the user to the destination floor (S306). As a result, the user can move to the destination floor in the car 2G, which is the allocation car.
　また、制御基板３Ｆ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６のＳ４０５）。利用者が乗場釦６ＦＧを押すと、乗場釦６ＦＧから制御基板３Ｆに対して、ネットワーク２３ＦＧを介して呼びの登録要求が送信される。利用者が乗場釦６ＨＩを押すと、乗場釦６ＨＩから制御基板３Ｆに対して、ネットワーク２３ＨＩ及びネットワーク２１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制御基板３Ｆが受信すると、Ｓ４０５でＹｅｓと判定される。割当部３２Ｆは、Ｓ４０５でＹｅｓと判定すると、Ｓ４０５で受信した登録要求に対する割当かごを決定する（Ｓ４０６）。 Further, on the control board 3F, it is determined in the normal allocation control whether or not the call registration request is received from the landing button 6 (S405 in FIG. 6). When the user presses the landing button 6FG, the landing button 6FG transmits a call registration request to the control board 3F via the network 23FG. When the user presses the landing button 6HI, a call registration request is transmitted from the landing button 6HI to the control board 3F via the network 23HI and the network 21. When the control board 3F receives the registration request transmitted from the landing button 6, it is determined as Yes in S405. When the allocation unit 32F determines Yes in S405, it determines the allocation car for the registration request received in S405 (S406).
　割当部３２Ｆは、Ｓ４０６において、かご２Ｆ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と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３２Ｆは、かご２Ｆ～２Ｉの中から割当かごを決定する。 In S406, the allocation unit 32F determines the allocation car from the cars controlled by the control board that can communicate with the car 2F via the network 21. If it is determined to be Yes in S102, the allocation unit 32F determines the allocation car from the cars 2F to 2I.
　指令部３３Ｆは、割当部３２Ｆ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（Ｓ４０７）。例えば、Ｇ号機のかご２Ｇが割当かごであれば、指令部３３Ｆ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。Ｓ４０７で送信される応答指令には、行先階の情報は含まれない。なお、Ｓ４０６で割当部３２Ｆがかご２Ｆを割当かごに決定すると、Ｓ４０７では、運行制御部３４Ｆが、かご２Ｆを利用者がいる乗場まで移動させるための応答制御を行う。この場合、Ｓ４０７において応答指令の送信は行われない。 The command unit 33F transmits a response command via the network 21 to the control board that controls the allocation car determined by the allocation unit 32F (S407). For example, if the car 2G of Unit G is an assigned car, the command unit 33F transmits a response command to the control board 3G via the network 21. The response command transmitted in S407 does not include information on the destination floor. When the allocation unit 32F determines the car 2F as the allocation car in S406, in S407, the operation control unit 34F performs response control for moving the car 2F to the landing where the user is. In this case, the response command is not transmitted in S407.
　また、指令部３３Ｆは、割当部３２Ｆが割当かごを決定すると、Ｓ４０５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等を介して応答信号を送信する（Ｓ４０８）。 Further, when the allocation unit 32F determines the allocation car, the command unit 33F transmits a response signal to the landing button 6 that has transmitted the registration request in S405 via the network 23 or the like (S408).
　乗場釦６では、Ｓ４０８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 S408. The user can know that the call has been registered by looking at the lit landing button 6.
　また、Ｓ４０７で指令部３３Ｆが送信した応答指令を制御基板３Ｈ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、運行制御部３４Ｈは、かご２Ｈを利用者がいる乗場まで移動させるための応答制御を行う（Ｓ２０６）。これにより、利用者は、割当かごであるかご２Ｈに乗ることができる。 Further, when the control board 3H receives the response command transmitted by the command unit 33F in S407, it is determined as Yes in S205 of FIG. If it is determined to be Yes in S205, the operation control unit 34H performs response control for moving the car 2H to the landing where the user is (S206). As a result, the user can ride in the car 2H, which is the allocation car.
　同様に、例えば、Ｓ４０７で指令部３３Ｆが送信した応答指令を制御基板３Ｇが受信すると、図５のＳ３０５でＹｅｓと判定される。Ｓ３０５でＹｅｓと判定されると、運行制御部３４Ｇは、かご２Ｇを利用者がいる乗場まで移動させるための応答制御を行う（Ｓ３０６）。これにより、利用者は、割当かごであるかご２Ｇに乗ることができる。 Similarly, for example, when the control board 3G receives the response command transmitted by the command unit 33F in S407, it is determined as Yes in S305 of FIG. If it is determined to be Yes in S305, the operation control unit 34G performs response control for moving the car 2G to the landing where the user is (S306). As a result, the user can ride in the car 2G, which is the allocation 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、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。Ｈ号機の制御盤の電源が落とされると、制御基板３Ｈは図４に示す動作を行うことができない。制御基板３Ｈは、ネットワーク２１から離脱する。このため、Ｓ１０１でノード判定部３１Ｆが参入要求を送信しても、制御基板３Ｈから制御基板３Ｆ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 H unit is performed, the power of the control panel of the H unit may be turned off. When the power of the control panel of Unit H is turned off, the control board 3H cannot perform the operation shown in FIG. The control board 3H is separated from the network 21. Therefore, even if the node determination unit 31F transmits an entry request in S101, the entry response is not transmitted from the control board 3H to the control board 3F. In S102, it is determined as No.
　Ｈ号機の保守が行われていても、制御基板３Ｇ及び制御基板３Ｉからは制御基板３Ｆに対して参入応答が送信される。Ｓ１０２でＮｏと判定されると、隔離検出部３５Ｆは、制御基板３Ｆがネットワーク２１から隔離されたか否かを判定する（Ｓ１０５）。ここで、「制御基板がネットワーク２１から隔離される」とは、当該制御基板の通信機能が停止していないにも関わらず、当該制御基板がネットワーク２１を介して他の制御基板と通信することができない」ことを意味する。Ｓ１０１でノード判定部３１Ｆが送信した参入要求に対して何れかの制御基板から参入応答を受信すれば、Ｓ１０５でＮｏと判定される。Ｓ１０５でＮｏと判定されると、Ｓ１０３の処理に進む。かかる場合、制御基板３Ｆは、ネットワーク２１から離脱した制御基板を制御対象から除外して通常割当制御を行う。 Even if the maintenance of Unit H is performed, the entry response is transmitted from the control board 3G and the control board 3I to the control board 3F. If No is determined in S102, the isolation detection unit 35F determines whether or not the control board 3F is isolated from the network 21 (S105). Here, "the control board is isolated from the network 21" means that the control board communicates with another control board via the network 21 even though the communication function of the control board is not stopped. I can't do it. " If an entry response is received from any of the control boards in response to the entry request transmitted by the node determination unit 31F in S101, it is determined as No in S105. If No is determined in S105, the process proceeds to S103. In such a case, the control board 3F excludes the control board separated from the network 21 from the control target and performs normal allocation control.
　次に、役割がマスタであるＦ号機の保守が行われる例について説明する。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３に示す動作を行うことができない。制御基板３Ｆは、ネットワーク２１から離脱する。このため、制御基板３Ｆから参入要求は送信されない。 Next, an example in which maintenance of Unit F, whose role is the master, is performed will be described. When the maintenance of Unit F is performed, the power of the control panel of Unit F 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. The control board 3F is separated from the network 21. Therefore, the entry request is not transmitted from the control board 3F.
　制御基板３Ｈでは、前回参入要求を受信してから一定の時間ＴＢＫＭＳＴが経過したか否かが判定される（図４のＳ２０７）。時間ＴＢＫＭＳＴは予め設定される。また、制御基板３Ｇ及び制御基板３Ｉにおいても、参入要求を前回受信してから一定の時間ＴＳＬＶが経過したか否かが判定される（図５のＳ３０７）。時間ＴＳＬＶは、時間ＴＢＫＭＳＴより長い時間に設定される。このため、制御基板３Ｆから参入要求が送信されなくなると、Ｓ３０７でＹｅｓと判定される前にＳ２０７でＹｅｓと判定される。 In the control board 3H, it is determined whether or not TBKMST has elapsed for a certain period of time since the previous entry request was received (S207 in FIG. 4). The time TBKMST is preset. Further, also in the control board 3G and the control board 3I, it is determined whether or not TSLV has elapsed for a certain period of time since the previous entry request was received (S307 in FIG. 5). The time T SLV is set to a time longer than the time T BKMST. Therefore, when the entry request is no longer transmitted from the control board 3F, it is determined as Yes in S207 before it is determined as Yes in S307.
　ノード判定部３１Ｈは、Ｓ２０７でＹｅｓと判定すると、制御基板３Ｈの役割をＢＫＭＳＴからＭＳＴに変更する（Ｓ２０８）。即ち、Ｓ２０７でＹｅｓと判定されることにより、システムの群管理機能は、制御基板３Ｈによって行われる。これにより、制御基板３Ｈでは、図３に示す動作が開始される。ノード判定部３１Ｈは、Ｓ２０７でＹｅｓと判定すると、他の制御基板に対して、ネットワーク２１を介して参入要求を送信する（Ｓ１０１）。例えば、Ｓ１０１では、制御基板３Ｈ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。 When the node determination unit 31H determines Yes in S207, the node determination unit 31H changes the role of the control board 3H from BKMST to MST (S208). That is, when it is determined to be Yes in S207, the group management function of the system is performed by the control board 3H. As a result, the operation shown in FIG. 3 is started on the control board 3H. When the node determination unit 31H determines Yes in S207, the node determination unit 31H transmits an entry request to another control board via the network 21 (S101). For example, in S101, the entry request is broadcast from the control board 3H to the network 21.
　制御基板３Ｇでは、Ｓ３０７でＹｅｓと判定される前に、ノード判定部３１ＨがＳ１０１で送信した参入要求を受信する（Ｓ３０１のＹｅｓ）。これにより、制御基板３Ｇでは、Ｓ３０２からＳ３０６に示す一連の処理が行われる。 In the control board 3G, the node determination unit 31H receives the entry request transmitted in S101 before the determination in S307 is Yes (Yes in S301). As a result, the control board 3G performs a series of processes shown in S302 to S306.
　次に、Ｆ号機の保守とＨ号機の保守とが同時に行われる例について説明する。Ｆ号機の保守が行われると、制御基板３Ｆから参入要求は送信されない。Ｈ号機の保守が行われると、制御基板３Ｈは、群管理機能を実行することができない。このため、制御基板３Ｇは参入要求を受信しない（Ｓ３０１のＮｏ）。Ｆ号機の保守とＨ号機の保守とが同時に行われると、ノード判定部３１Ｇは、時間ＴＳＬＶが経過することによってＳ３０７でＹｅｓと判定する。同様に、ノード判定部３１Ｉは、時間ＴＳＬＶが経過することによってＳ３０７でＹｅｓと判定する。 Next, an example in which the maintenance of the F unit and the maintenance of the H unit are performed at the same time will be described. When the maintenance of Unit F is performed, the entry request is not transmitted from the control board 3F. When the maintenance of Unit H is performed, the control board 3H cannot execute the group management function. Therefore, the control board 3G does not receive the entry request (No in S301). When the maintenance of the F unit and the maintenance of the H unit are performed at the same time, the node determination unit 31G determines Yes in S307 as the time TSLV elapses. Similarly, the node determining unit 31I determines Yes in S307 by the elapsed time T SLV.
　隔離検出部３５Ｇは、Ｓ３０７でＹｅｓと判定されると、制御基板３Ｇがネットワーク２１から隔離されたことを検出する（Ｓ３０８）。制御基板３Ｇが隔離されたことが隔離検出部３５Ｇによって検出されると、隔離判定部３６Ｇは、ネットワーク２１から隔離された他の制御基板が存在するか否かを判定する。隔離判定部３６Ｇによるこの判定は、他の制御基板からのヘルスチェック信号に基づいて行われる。 When the isolation detection unit 35G determines Yes in S307, it detects that the control board 3G has been isolated from the network 21 (S308). When the isolation detection unit 35G detects that the control board 3G has been isolated, the isolation determination unit 36G determines whether or not there is another control board isolated from the network 21. This determination by the isolation determination unit 36G is performed based on the health check signal from another control board.
　例えば、隔離判定部３６Ｇは、Ｓ３０７でＹｅｓと判定されると、他の制御基板、即ち制御基板３Ｆ、３Ｈ、及び３Ｉに対して、ネットワーク２２を介してヘルスチェック信号を送信する（Ｓ３０９）。また、隔離判定部３６Ｇは、他の制御基板、即ち制御基板３Ｆ、３Ｈ、及び３Ｉからヘルスチェック信号を受信したか否かを判定する（Ｓ３１０）。 For example, when the isolation determination unit 36G determines Yes in S307, it transmits a health check signal to other control boards, that is, control boards 3F, 3H, and 3I via the network 22 (S309). Further, the isolation determination unit 36G determines whether or not a health check signal has been received from other control boards, that is, control boards 3F, 3H, and 3I (S310).
　同様に、隔離検出部３５Ｉは、Ｓ３０７でＹｅｓと判定されると、制御基板３Ｉがネットワーク２１から隔離されたことを検出する（Ｓ３０８）。制御基板３Ｉが隔離されたことが隔離検出部３５Ｉによって検出されると、隔離判定部３６Ｉは、ネットワーク２１から隔離された他の制御基板が存在するか否かを判定する。隔離判定部３６Ｉによるこの判定は、他の制御基板からのヘルスチェック信号に基づいて行われる。 Similarly, when the isolation detection unit 35I determines Yes in S307, it detects that the control board 3I has been isolated from the network 21 (S308). When the isolation detection unit 35I detects that the control board 3I has been isolated, the isolation determination unit 36I determines whether or not there is another control board isolated from the network 21. This determination by the isolation determination unit 36I is performed based on the health check signal from another control board.
　例えば、隔離判定部３６Ｉは、Ｓ３０７でＹｅｓと判定されると、他の制御基板、即ち制御基板３Ｆ～３Ｈに対して、ネットワーク２２を介してヘルスチェック信号を送信する（Ｓ３０９）。また、隔離判定部３６Ｉは、他の制御基板、即ち制御基板３Ｆ～３Ｈからヘルスチェック信号を受信したか否かを判定する（Ｓ３１０）。 For example, when the isolation determination unit 36I determines Yes in S307, it transmits a health check signal to another control board, that is, control boards 3F to 3H, via the network 22 (S309). Further, the isolation determination unit 36I determines whether or not a health check signal has been received from another control board, that is, control boards 3F to 3H (S310).
　隔離判定部３６ＩがＳ３０９で送信したヘルスチェック信号は、ネットワーク２２を介して制御基板３Ｇによって受信される（Ｓ３１０のＹｅｓ）。これにより、隔離判定部３６Ｇは、制御基板３Ｉがネットワーク２１から隔離されたことを検出する。即ち、隔離判定部３６Ｇは、ネットワーク２１から隔離された他の制御基板が存在することを判定する。運行制御部３４Ｇは、Ｓ３１０でＹｅｓと判定されると、自系列の乗場機器からの登録要求のみに応答するように応答制御を行う（Ｓ３１１）。 The health check signal transmitted by the isolation determination unit 36I in S309 is received by the control board 3G via the network 22 (Yes in S310). As a result, the isolation determination unit 36G detects that the control board 3I has been isolated from the network 21. That is, the isolation determination unit 36G determines that another control board isolated from the network 21 exists. When the operation control unit 34G determines Yes in S310, the operation control unit 34G performs response control so as to respond only to the registration request from the landing equipment of its own series (S311).
　例えば、乗場操作盤４ＦＧ、乗場釦６ＦＧ、制御基板３Ｆ、及び制御基板３Ｇは、第１系列に予め設定される。このため、運行制御部３４Ｇは、Ｓ３１０でＹｅｓと判定されると、乗場操作盤４ＦＧからの登録要求にかご２Ｇを応答させる制御を行う。また、運行制御部３４Ｇは、乗場釦６ＦＧからの登録要求にかご２Ｇを応答させる制御を行う。Ｓ３１０でＹｅｓと判定されると、運行制御部３４Ｇは、乗場操作盤４ＨＩからの登録要求にかご２Ｇを応答させない。運行制御部３４Ｇは、乗場釦６ＨＩからの登録要求にかご２Ｇを応答させない。 For example, the landing operation panel 4FG, the landing button 6FG, the control board 3F, and the control board 3G are preset in the first series. Therefore, when the operation control unit 34G determines Yes in S310, the operation control unit 34G controls the car 2G to respond to the registration request from the landing operation panel 4FG. In addition, the operation control unit 34G controls the car 2G to respond to the registration request from the landing button 6FG. If it is determined to be Yes in S310, the operation control unit 34G does not respond to the registration request from the landing operation panel 4HI. The operation control unit 34G does not respond to the registration request from the landing button 6HI from the car 2G.
　同様に、隔離判定部３６ＧがＳ３０９で送信したヘルスチェック信号は、ネットワーク２２を介して制御基板３Ｉによって受信される（Ｓ３１０のＹｅｓ）。これにより、隔離判定部３６Ｉは、制御基板３Ｇがネットワーク２１から隔離されたことを検出する。即ち、隔離判定部３６Ｉは、ネットワーク２１から隔離された他の制御基板が存在することを判定する。運行制御部３４Ｉは、Ｓ３１０でＹｅｓと判定されると、自系列の乗場機器からの登録要求のみに応答するように応答制御を行う（Ｓ３１１）。 Similarly, the health check signal transmitted by the isolation determination unit 36G in S309 is received by the control board 3I via the network 22 (Yes in S310). As a result, the isolation determination unit 36I detects that the control board 3G has been isolated from the network 21. That is, the isolation determination unit 36I determines that another control board isolated from the network 21 exists. When the operation control unit 34I determines Yes in S310, the operation control unit 34I performs response control so as to respond only to the registration request from the landing equipment of its own series (S311).
　例えば、乗場操作盤４ＨＩ、乗場釦６ＨＩ、制御基板３Ｈ、及び制御基板３Ｉは、第２系列に予め設定される。第２系列は、第１系列とは異なる系列である。このため、運行制御部３４Ｉは、Ｓ３１０でＹｅｓと判定されると、乗場操作盤４ＨＩからの登録要求にかご２Ｉを応答させる制御を行う。また、運行制御部３４Ｉは、乗場釦６ＨＩからの登録要求にかご２Ｉを応答させる制御を行う。Ｓ３１０でＹｅｓと判定されると、運行制御部３４Ｉは、乗場操作盤４ＦＧからの登録要求にかご２Ｉを応答させない。運行制御部３４Ｉは、乗場釦６ＦＧからの登録要求にかご２Ｉを応答させない。 For example, the landing operation panel 4HI, the landing button 6HI, the control board 3H, and the control board 3I are preset in the second series. The second series is a series different from the first series. Therefore, when the operation control unit 34I determines Yes in S310, the operation control unit 34I controls the car 2I to respond to the registration request from the landing operation panel 4HI. In addition, the operation control unit 34I controls the car 2I to respond to the registration request from the landing button 6HI. If it is determined to be Yes in S310, the operation control unit 34I does not respond to the registration request from the landing operation panel 4FG. The operation control unit 34I does not respond to the registration request from the landing button 6FG with the car 2I.
　一方、隔離判定部３６Ｇは、他の制御基板からヘルスチェック信号を受信しなければ（Ｓ３１０のＮｏ）、ネットワーク２１から隔離された他の制御基板が存在しないことを判定する。運行制御部３４Ｇは、Ｓ３１０でＮｏと判定されると、自系列の乗場機器だけでなく、他系列の乗場機器からの登録要求にも応答するように応答制御を行う（Ｓ３１２）。即ち、運行制御部３４Ｇは、全ての乗場機器からの登録要求にかご２Ｇを応答させる。例えば、運行制御部３４Ｇは、乗場操作盤４ＦＧからの登録要求にかご２Ｇを応答させる。運行制御部３４Ｇは、乗場操作盤４ＨＩからの登録要求にかご２Ｇを応答させる。運行制御部３４Ｇは、乗場釦６ＦＧからの登録要求にかご２Ｇを応答させる。運行制御部３４Ｇは、乗場釦６ＨＩからの登録要求にかご２Ｇを応答させる。 On the other hand, the isolation determination unit 36G determines that there is no other control board isolated from the network 21 unless a health check signal is received from another control board (No in S310). When the operation control unit 34G determines No in S310, the operation control unit 34G performs response control so as to respond not only to the landing equipment of its own series but also to the registration request from the landing equipment of another series (S312). That is, the operation control unit 34G responds to the registration request from all the landing equipment with the car 2G. For example, the operation control unit 34G causes the car 2G to respond to the registration request from the landing operation panel 4FG. The operation control unit 34G responds to the registration request from the landing operation panel 4HI with the car 2G. The operation control unit 34G responds to the registration request from the landing button 6FG with the car 2G. The operation control unit 34G responds to the registration request from the landing button 6HI with the car 2G.
　同様に、隔離判定部３６Ｉは、他の制御基板からヘルスチェック信号を受信しなければ（Ｓ３１０のＮｏ）、ネットワーク２１から隔離された他の制御基板が存在しないことを判定する。運行制御部３４Ｉは、Ｓ３１０でＮｏと判定されると、自系列の乗場機器だけでなく、他系列の乗場機器からの登録要求にも応答するように応答制御を行う（Ｓ３１２）。即ち、運行制御部３４Ｉは、全ての乗場機器からの登録要求にかご２Ｇを応答させる。例えば、運行制御部３４Ｉは、乗場操作盤４ＦＧからの登録要求にかご２Ｉを応答させる。運行制御部３４Ｉは、乗場操作盤４ＨＩからの登録要求にかご２Ｉを応答させる。運行制御部３４Ｉは、乗場釦６ＦＧからの登録要求にかご２Ｉを応答させる。運行制御部３４Ｉは、乗場釦６ＨＩからの登録要求にかご２Ｉを応答させる。 Similarly, the isolation determination unit 36I determines that there is no other control board isolated from the network 21 unless a health check signal is received from another control board (No in S310). When the operation control unit 34I determines No in S310, the operation control unit 34I performs response control so as to respond not only to the landing equipment of its own series but also to the registration request from the landing equipment of another series (S312). That is, the operation control unit 34I makes the car 2G respond to the registration request from all the landing equipment. For example, the operation control unit 34I causes the car 2I to respond to the registration request from the landing operation panel 4FG. The operation control unit 34I responds to the registration request from the landing operation panel 4HI with the car 2I. The operation control unit 34I responds to the registration request from the landing button 6FG with the car 2I. The operation control unit 34I responds to the registration request from the landing button 6HI with the car 2I.
　なお、役割がマスタである制御基板でも、ネットワーク２１から隔離されたことが検出されると、上記と同様の動作が行われる。即ち、隔離検出部３５Ｆは、Ｓ１０１でノード判定部３１Ｆが送信した参入要求に対して参入応答を全く受信しなければ、制御基板３Ｆがネットワーク２１から隔離されたことを検出する（Ｓ１０５のＹｅｓ）。制御基板３Ｆが隔離されたことが隔離検出部３５Ｆによって検出されると、隔離判定部３６Ｆは、ネットワーク２１から隔離された他の制御基板が存在するか否かを判定する。隔離判定部３６Ｆによるこの判定は、他の制御基板からのヘルスチェック信号に基づいて行われる。 Even in the control board whose role is the master, when it is detected that the control board is isolated from the network 21, the same operation as described above is performed. That is, the isolation detection unit 35F detects that the control board 3F has been isolated from the network 21 if no entry response is received in response to the entry request transmitted by the node determination unit 31F in S101 (Yes in S105). .. When the isolation detection unit 35F detects that the control board 3F has been isolated, the isolation determination unit 36F determines whether or not there is another control board isolated from the network 21. This determination by the isolation determination unit 36F is performed based on the health check signal from another control board.
　例えば、隔離判定部３６Ｆは、Ｓ１０５でＹｅｓと判定されると、他の制御基板、即ち制御基板３Ｇ～３Ｉに対して、ネットワーク２２を介してヘルスチェック信号を送信する（Ｓ１０６）。また、隔離判定部３６Ｆは、他の制御基板、即ち制御基板３Ｇ～３Ｉからヘルスチェック信号を受信したか否かを判定する（Ｓ１０７）。 For example, when the isolation determination unit 36F determines Yes in S105, it transmits a health check signal to another control board, that is, control boards 3G to 3I, via the network 22 (S106). Further, the isolation determination unit 36F determines whether or not a health check signal has been received from another control board, that is, control boards 3G to 3I (S107).
　例えば、他の制御基板が送信したヘルスチェック信号を制御基板３Ｆがネットワーク２２を介して受信すると（Ｓ１０７のＹｅｓ）、隔離判定部３６Ｆは、当該他の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。即ち、隔離判定部３６Ｆは、ネットワーク２１から隔離された他の制御基板が存在することを判定する。運行制御部３４Ｆは、Ｓ１０７でＹｅｓと判定されると、自系列の乗場機器からの登録要求のみに応答するように応答制御を行う（Ｓ１０８）。 For example, when the control board 3F receives the health check signal transmitted by the other control board via the network 22 (Yes in S107), the isolation determination unit 36F indicates that the other control board has been isolated from the network 21. To detect. That is, the isolation determination unit 36F determines that another control board isolated from the network 21 exists. When the operation control unit 34F determines Yes in S107, the operation control unit 34F performs response control so as to respond only to the registration request from the landing equipment of its own series (S108).
　一方、隔離判定部３６Ｆは、他の制御基板からヘルスチェック信号を受信しなければ（Ｓ１０７のＮｏ）、ネットワーク２１から隔離された他の制御基板が存在しないことを判定する。運行制御部３４Ｆは、Ｓ１０７でＮｏと判定されると、自系列の乗場機器だけでなく、他系列の乗場機器からの登録要求にも応答するように応答制御を行う（Ｓ１０９）。即ち、運行制御部３４Ｆは、全ての乗場機器からの登録要求にかご２Ｆを応答させる。 On the other hand, the isolation determination unit 36F determines that there is no other control board isolated from the network 21 unless a health check signal is received from another control board (No in S107). When No is determined in S107, the operation control unit 34F performs response control so as to respond not only to the landing equipment of its own series but also to the registration request from the landing equipment of another series (S109). That is, the operation control unit 34F makes the car 2F respond to the registration request from all the landing equipment.
　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、制御基板３Ｇは、他の制御基板の隔離の状況に合わせて呼びの登録要求にかご２Ｇを応答させる。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 control board 3G responds to the call registration request according to the isolation status of the other control boards. 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.

The semiconductor memory that can be adopted includes RAM, ROM, flash memory, EPROM, EEPROM, and the like.
　図９は、制御基板３Ｆのハードウェア資源の他の例を示す図である。図９に示す例では、制御基板３Ｆ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９は、制御基板３Ｆ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。制御基板３Ｆ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. 9 is a diagram showing another example of the hardware resource of the control board 3F. In the example shown in FIG. 9, the control board 3F includes, for example, a processing circuit 40 including a processor 41, a memory 42, and dedicated hardware 43.
