しかしながら、特許文献１に記載のエレベータシステムにおいては、各階の乗場戸開検出用接点が互いに直列に接続されている。このため、かごの停止階においてかご戸と乗場戸とが開いている場合、かごの停止階以外の階で乗場戸が開いていることを検出できない。   However, in the elevator system described in Patent Literature 1, the contact door detection contacts on each floor are connected in series with each other. For this reason, when the car door and the landing door are open on the stop floor of the car, it cannot be detected that the landing door is open on a floor other than the stop floor of the car.

この発明は、上述の課題を解決するためになされた。この発明の目的は、かごの停止階においてかご戸と乗場戸が開いている場合でも、かごの停止階以外の階で乗場戸が開いていることを検出できるエレベータシステムを提供することである。   The present invention has been made to solve the above-described problems. An object of the present invention is to provide an elevator system capable of detecting that a landing door is open on a floor other than the stop floor of the car even when the car door and the landing door are open on the stop floor of the car.

この発明に係るエレベータシステムは、戸開許可ゾーンがそれぞれ設定された複数の乗場戸と、昇降路の内部において前記複数の乗場戸の位置に応じてそれぞれ設けられ、エレベータのかごが対応する戸開許可ゾーンに進入したことを検出する複数の第２戸開許可ゾーン検出回路と、昇降路の内部において前記複数の乗場戸の位置に応じてそれぞれ設けられ、対応する乗場戸の開閉状態に応じて開閉状態が変化する乗場戸開検出用接点を有し、対応する第２戸開許可ゾーン検出回路が前記かごが前記対応する戸開許可ゾーンに進入したことを検出すると前記乗場戸開検出用接点の両端を短絡する複数の乗場戸開検出装置と、前記複数の乗場戸開検出用接点を直列に接続する配線と接続し、前記複数の第２戸開許可ゾーン検出回路の検出状態及び前記複数の乗場戸開検出用接点の状態に基づいて前記かごが戸開許可ゾーンに進入している乗場戸以外の乗場戸が開いていることを検出する制御盤と、を備えた。   The elevator system according to the present invention is provided with a plurality of landing doors each having a door opening permission zone, and a door opening corresponding to the position of the plurality of landing doors in the hoistway. A plurality of second door opening permission zone detection circuits for detecting the entry into the permission zone, and provided in accordance with the positions of the plurality of landing doors in the hoistway, respectively, according to the open / closed state of the corresponding landing doors A contact point for detecting the opening of the landing door that changes its open / close state, and when the corresponding second door opening permission zone detection circuit detects that the car has entered the corresponding door opening permission zone, the contact point for detecting the opening of the landing door A plurality of landing door opening detection devices that short-circuit both ends of the door, and a wiring that connects the plurality of landing door opening detection contacts in series, and detection states of the plurality of second door opening permission zone detection circuits And a control panel which detects that the landing doors other than landing units of the car based on a state of said plurality of landing door open detection contact is entering the door open authorized zone is open.

この発明によれば、乗場戸開検出装置は、かごが対応階の戸開許可ゾーンに進入した際に対応した乗場戸開検出用接点の両側を短絡させる。このため、かごの停止階においてかご戸と乗場戸とが開いている場合でも、かごの停止階以外の階で乗場戸が開いていることを検出できる。   According to the present invention, the landing door opening detection device short-circuits both sides of the corresponding landing door opening detection contact when the car enters the door opening permission zone of the corresponding floor. For this reason, even when the car door and the landing door are open on the stop floor of the car, it can be detected that the landing door is open on a floor other than the stop floor of the car.

制御盤７は、エレベータ全体を制御する。例えば、制御盤７は、かご１の昇降を制御する。   The control panel 7 controls the entire elevator. For example, the control panel 7 controls the raising / lowering of the car 1.

エレベータシステムにおいて、複数の戸開許可ゾーンの各々は、乗場戸１ｂの設置位置に応じて設定される。複数の戸開許可ゾーンの各々は、対応階においてかご戸１ａと乗場戸１ｂとが開き得る位置に設定される。   In the elevator system, each of the plurality of door opening permission zones is set according to the installation position of the landing door 1b. Each of the plurality of door opening permission zones is set at a position where the car door 1a and the landing door 1b can be opened on the corresponding floor.

かご１がいずれの階の戸開許可ゾーンにも進入していないと、第１戸開許可ゾーン検出回路４は、いずれの第１戸開許可ゾーン検出器２も検出しない。この際、第１戸開許可ゾーン検出回路４は、かご１が戸開許可ゾーンに進入していることを示す戸開許可ゾーン進入信号Ｂを制御盤７に送信しない。制御盤７は、戸開許可ゾーン進入信号Ｂを受信しないことによりかご１がいずれの階の戸開許可ゾーンにも進入していないことを検出する。   If the car 1 has not entered the door opening permission zone on any floor, the first door opening permission zone detection circuit 4 does not detect any first door opening permission zone detector 2. At this time, the first door opening permission zone detection circuit 4 does not transmit the door opening permission zone entry signal B indicating that the car 1 has entered the door opening permission zone to the control panel 7. The control panel 7 detects that the car 1 has not entered the door opening permission zone of any floor by not receiving the door opening permission zone entering signal B.

この際、全ての第２戸開許可ゾーン検出回路５は、第２戸開許可ゾーン検出器３を検出しない。全ての第２戸開許可ゾーン検出回路５が第２戸開許可ゾーン検出器３を検出しないと、全ての戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給されない。   At this time, all the second door opening permission zone detection circuits 5 do not detect the second door opening permission zone detector 3. If all the second door opening permission zone detection circuits 5 do not detect the second door opening permission zone detector 3, electric power is not supplied to the primary side of all the door opening permission zone detection a contacts 10.

全ての戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給されないと、対応階の第１コイル１１が消磁される。全ての第１コイル１１が消磁されると、全ての第１コイル用ｂ接点１４が閉じる。全ての第１コイル用第２ａ接点１６が開く。全ての第１コイル用第２ａ接点１６が開くと、全ての第２コイル１２が消磁される。全ての第２コイル１２が消磁されると、全ての第２コイル用ｂ接点１８が閉じる。対応階の第２コイル用ｂ接点１８が閉じると、第３コイル１３が励磁される。   If power is not supplied to the primary side of all the door opening permission zone detection a contacts 10, the first coil 11 on the corresponding floor is demagnetized. When all the first coils 11 are demagnetized, all the first coil b contacts 14 are closed. All the first coil second-a contacts 16 are opened. When all the first coil second a contacts 16 are opened, all the second coils 12 are demagnetized. When all the second coils 12 are demagnetized, all the second coil b contacts 18 are closed. When the b contact 18 for the second coil on the corresponding floor is closed, the third coil 13 is excited.

その結果、全ての第１コイル用第３ａ接点１７と全ての第２コイル用第２ａ接点２０と全ての第３コイル用ｂ接点２４とは開く。このため、全ての乗場戸開検出用ｂ接点９の両側は、短絡されない。   As a result, all the first coil 3a contacts 17, all the second coil 2a contacts 20, and all the third coil b contacts 24 are opened. For this reason, both sides of all the contact door open detection b contacts 9 are not short-circuited.

かご１がいずれかの階の戸開許可ゾーンに進入すると、第１戸開許可ゾーン検出回路４は、対応階の第１戸開許可ゾーン検出器２を検出する。この際、第１戸開許可ゾーン検出回路４は、戸開許可ゾーン進入信号Ｂを送信する。制御盤７は、当該戸開許可ゾーン進入信号Ｂを受信することによりかご１がいずれかの階の戸開許可ゾーンに進入していることを検出する。   When the car 1 enters the door opening permission zone on any floor, the first door opening permission zone detection circuit 4 detects the first door opening permission zone detector 2 on the corresponding floor. At this time, the first door opening permission zone detection circuit 4 transmits a door opening permission zone entry signal B. The control panel 7 detects that the car 1 has entered the door opening permission zone of any floor by receiving the door opening permission zone entering signal B.

この際、対応階の第２戸開許可ゾーン検出回路５は、第２戸開許可ゾーン検出器３を検出する。対応階の第２戸開許可ゾーン検出回路５が第２戸開許可ゾーン検出器３を検出すると、対応階の戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給される。   At this time, the second door opening permission zone detection circuit 5 on the corresponding floor detects the second door opening permission zone detector 3. When the second door opening permission zone detection circuit 5 on the corresponding floor detects the second door opening permission zone detector 3, electric power is supplied to the primary side of the contact opening 10 for detecting the door opening permission zone on the corresponding floor.

対応階の戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給されると、対応階の第１コイル１１が励磁される。対応階の第１コイル１１が励磁されると、対応階の第１コイル用第２ａ接点１６が閉じる。対応階の第１コイル用第２ａ接点１６が閉じると、対応階の第２コイル１２が励磁される。対応階の第２コイル１２が励磁されると、対応階の第２コイル用ｂ接点１８が開く。対応階の第２コイル用ｂ接点１８が開くと、第３コイル１３が消磁される。   When power is supplied to the primary side of the door opening permission zone detection a contact 10 on the corresponding floor, the first coil 11 on the corresponding floor is excited. When the first coil 11 on the corresponding floor is excited, the second coil contact 2a 16 on the corresponding floor is closed. When the first coil second a contact 16 on the corresponding floor is closed, the second coil 12 on the corresponding floor is excited. When the second coil 12 on the corresponding floor is excited, the b contact 18 for the second coil on the corresponding floor opens. When the b contact 18 for the second coil on the corresponding floor is opened, the third coil 13 is demagnetized.

その結果、対応階の第１コイル用第３ａ接点１７と対応階の第２コイル用第２ａ接点２０と対応階の第３コイル用ｂ接点２４とは閉じる。このため、対応階の乗場戸開検出用ｂ接点９の両側は、短絡される。   As a result, the first coil 3a contact 17 on the corresponding floor, the second coil 2a contact 20 on the corresponding floor, and the third coil b contact 24 on the corresponding floor are closed. For this reason, both sides of the b-contact 9 for detecting the door opening on the corresponding floor are short-circuited.

この状態において、制御盤７は、対応階の乗場戸１ｂを開く。対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断されていない。その結果、複数の乗場戸開検出用ｂ接点９が直列に接続された配線は、一定の電圧を保つ。この場合、いずれの乗場戸開検出装置６も、乗場戸１ｂが開いていることを示す乗場戸開検出信号Ａを制御盤７に送信しない。制御盤７は、乗場戸開検出信号Ａを受信しないことによりかご１にいずれの階の乗場戸１ｂも開いていないと検出する。   In this state, the control panel 7 opens the landing door 1b on the corresponding floor. When the corresponding floor landing door 1b is opened, the corresponding floor landing door detection b contact 9 is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is not cut off. As a result, the wiring in which the plurality of landing door open detection b contacts 9 are connected in series maintains a constant voltage. In this case, none of the landing door open detection devices 6 transmits the landing door open detection signal A indicating that the landing door 1b is open to the control panel 7. The control panel 7 detects that the landing door 1b of any floor is not open in the car 1 by not receiving the landing door open detection signal A.

これに対し、対応階以外の階の乗場戸１ｂが何らかの理由により開くと、当該階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａは、送信される。制御盤７は、乗場戸開検出信号Ａに基づいてかご１が戸開許可ゾーンに進入している階以外の階の乗場戸１ｂが開いていることを検出する。   On the other hand, when the landing door 1b on the floor other than the corresponding floor is opened for some reason, the landing contact open detection b contact 9 on the floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. Based on the landing door open detection signal A, the control panel 7 detects that the landing doors 1b of floors other than the floor where the car 1 enters the door opening permission zone are open.

かご１がいずれかの階の戸開許可ゾーンから脱出すると、第１戸開許可ゾーン検出回路４は、対応階の第１戸開許可ゾーン検出器２を検出しない。この際、第１戸開許可ゾーン検出回路４は、戸開許可ゾーン進入信号Ｂを送信しない。制御盤７は、当該戸開許可ゾーン進入信号Ｂを受信しないことによりかご１がいずれの階の戸開許可ゾーンにも進入していないことを検出する。   When the car 1 escapes from the door opening permission zone on any floor, the first door opening permission zone detection circuit 4 does not detect the first door opening permission zone detector 2 on the corresponding floor. At this time, the first door opening permission zone detection circuit 4 does not transmit the door opening permission zone entry signal B. The control panel 7 detects that the car 1 has not entered the door opening permission zone of any floor by not receiving the door opening permission zone entering signal B.

この際、対応階の第２戸開許可ゾーン検出回路５は、第２戸開許可ゾーン検出器３を検出しない。対応階の第２戸開許可ゾーン検出回路５が第２戸開許可ゾーン検出器３を検出しないと、対応階の戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給されない。   At this time, the second door opening permission zone detection circuit 5 on the corresponding floor does not detect the second door opening permission zone detector 3. If the second door opening permission zone detection circuit 5 on the corresponding floor does not detect the second door opening permission zone detector 3, power is not supplied to the primary side of the contact opening 10 for detecting the door opening permission zone on the corresponding floor.

対応階の戸開許可ゾーン検出用ａ接点１０の一次側に電力が供給されないと、対応階の第１コイル１１が消磁される。対応階の第１コイル１１が消磁されると、対応階の第１コイル用第２ａ接点１６が開く。対応階の第１コイル用第２ａ接点１６が開くと、対応階の第２コイル１２が消磁される。対応階の第２コイル１２が消磁されると、対応階の第２コイル用ｂ接点１８が閉じる。対応階の第２コイル用ｂ接点１８が閉じると、第３コイル１３が励磁される。   If power is not supplied to the primary side of the door opening permission zone detection a contact 10 on the corresponding floor, the first coil 11 on the corresponding floor is demagnetized. When the first coil 11 on the corresponding floor is demagnetized, the first coil second a contact 16 on the corresponding floor opens. When the first coil second a contact 16 on the corresponding floor is opened, the second coil 12 on the corresponding floor is demagnetized. When the second coil 12 on the corresponding floor is demagnetized, the b contact 18 for the second coil on the corresponding floor is closed. When the b contact 18 for the second coil on the corresponding floor is closed, the third coil 13 is excited.

その結果、対応階の第１コイル用第３ａ接点１７と対応階の第２コイル用第２ａ接点２０と対応階の第３コイル用ｂ接点２４とは開く。このため、対応階の乗場戸開検出用ｂ接点９の両側は、短絡されない。   As a result, the first coil 3a contact 17 on the corresponding floor, the second coil 2a contact 20 on the corresponding floor, and the third coil b contact 24 on the corresponding floor open. For this reason, both sides of the b-contact 9 for detecting the door opening of the corresponding floor are not short-circuited.

例えば、かご１が対応階の戸開許可ゾーンに進入している際に対応階の第１コイル１１において常に励磁される故障が発生する場合がある。この場合、かご１が対応階の戸開許可ゾーンから脱出しても、対応階の第１コイル用ｂ接点１４は閉じない。その結果、第３コイル１３は、励磁されない。その後、かご１が対応階の戸開許可ゾーンに再び進入しても、第２コイル１２は、励磁されない。このため、第２コイル用第２ａ接点２０は閉じない。   For example, when the car 1 enters the door opening permission zone on the corresponding floor, a failure that is always excited in the first coil 11 on the corresponding floor may occur. In this case, even if the car 1 escapes from the door opening permission zone on the corresponding floor, the first coil b-contact 14 on the corresponding floor does not close. As a result, the third coil 13 is not excited. Thereafter, even when the car 1 enters the door opening permission zone on the corresponding floor again, the second coil 12 is not excited. For this reason, the second coil second a contact 20 is not closed.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

例えば、かご１が対応階の戸開許可ゾーンから脱出している際に対応階の第１コイル１１において常に消磁される故障が発生する場合がある。この場合、かご１が対応階の戸開許可ゾーンに進入しても、第１コイル用第２ａ接点１６が閉じない。このため、第２コイル１２が励磁されない。第２コイル１２が励磁されないと、第２コイル用ｂ接点１８が開かない。第２コイル用ｂ接点１８が開かないと、第３コイル１３が消磁されない。このため、第２コイル用第２ａ接点２０と第３コイル用ｂ接点２４とは閉じない。   For example, when the car 1 escapes from the door opening permission zone on the corresponding floor, there may be a failure that is always demagnetized in the first coil 11 on the corresponding floor. In this case, even if the car 1 enters the door opening permission zone on the corresponding floor, the second coil contact 2a 16 does not close. For this reason, the second coil 12 is not excited. If the second coil 12 is not excited, the second coil b-contact 18 is not opened. If the second coil b contact 18 is not opened, the third coil 13 is not demagnetized. Therefore, the second coil second contact 20 and the third coil b contact 24 are not closed.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

例えば、かご１が対応階の戸開許可ゾーンに進入している際に対応階の第２コイル１２において常に励磁される故障が発生する場合がある。この場合、かご１が対応階の戸開許可ゾーンから脱出しても、対応階の第２コイル用ｂ接点１８が閉じない。その結果、第３コイル１３は、励磁されない。その後、かご１が対応階の戸開許可ゾーンに再び進入しても、第１コイル１１は、励磁されない。このため、第１コイル用第３ａ接点１７は閉じない。   For example, when the car 1 enters the door opening permission zone on the corresponding floor, a failure that is always excited in the second coil 12 on the corresponding floor may occur. In this case, even if the car 1 escapes from the door opening permission zone on the corresponding floor, the b contact 18 for the second coil on the corresponding floor does not close. As a result, the third coil 13 is not excited. Thereafter, even when the car 1 enters the door opening permission zone on the corresponding floor again, the first coil 11 is not excited. For this reason, the 3a contact 17 for 1st coils does not close.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

例えば、かご１が対応階の戸開許可ゾーンから脱出している際に対応階の第２コイル１２が常に消磁される故障が発生する場合がある。この場合、かご１が対応階の戸開許可ゾーンに進入しても、第２コイル用第１ａ接点１９が閉じない。このため、第２コイル１２が励磁されない。第２コイル１２が励磁されないと、第２コイル用ｂ接点１８が開かない。第２コイル用ｂ接点１８が開かないと、第３コイル１３が消磁されない。このため、第２コイル用第２ａ接点２０と第３コイル用ｂ接点２４とは閉じない。   For example, when the car 1 escapes from the door opening permission zone on the corresponding floor, a failure may occur in which the second coil 12 on the corresponding floor is always demagnetized. In this case, even when the car 1 enters the door opening permission zone on the corresponding floor, the second coil first contact 19 is not closed. For this reason, the second coil 12 is not excited. If the second coil 12 is not excited, the second coil b-contact 18 is not opened. If the second coil b contact 18 is not opened, the third coil 13 is not demagnetized. Therefore, the second coil second contact 20 and the third coil b contact 24 are not closed.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

例えば、かご１が対応階の戸開許可ゾーンから脱出している際に対応階の第３コイル１３において常に励磁される故障が発生する場合がある。この場合、かご１が対応階の戸開許可ゾーンに進入しても、第３コイル用ｂ接点２４は閉じない。   For example, when the car 1 escapes from the door opening permission zone on the corresponding floor, a failure that is always excited in the third coil 13 on the corresponding floor may occur. In this case, even if the car 1 enters the door opening permission zone on the corresponding floor, the third coil b-contact 24 does not close.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened.

For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

例えば、かご１が対応階の戸開許可ゾーンに進入している際に対応階の第３コイル１３が常に消磁される故障が発生する場合がある。その後、かご１が対応階の戸開許可ゾーンに進入しても、第１コイル１１が励磁されない。第１コイル１１が励磁されないと、第１コイル用第２ａ接点１６が閉じない。第１コイル用第２ａ接点１６が閉じないと、第２コイル１２が励磁されない。このため、第１コイル用第３ａ接点１７と第２コイル用第２ａ接点２０とは閉じない。   For example, when the car 1 enters the door opening permission zone on the corresponding floor, a failure may occur in which the third coil 13 on the corresponding floor is always demagnetized. Thereafter, even when the car 1 enters the door opening permission zone on the corresponding floor, the first coil 11 is not excited. If the first coil 11 is not excited, the first coil second contact 16 will not close. The second coil 12 is not excited unless the first coil second a contact 16 is closed. Therefore, the first coil third-a contact 17 and the second coil second-a contact 20 are not closed.

この状態において、対応階の乗場戸１ｂが開くと、対応階の乗場戸開検出用ｂ接点９が開く。この際、複数の乗場戸開検出用ｂ接点９が直列に接続された配線の導通は遮断される。このため、乗場戸開検出信号Ａが送信される。制御盤７は、乗場戸開検出信号Ａを受信することによりいずれかの乗場戸開検出装置６の故障を検出する。   In this state, when the landing door 1b on the corresponding floor is opened, the b-contact 9 for detecting the opening of the landing door on the corresponding floor is opened. At this time, the continuity of the wiring in which the plurality of landing door open detection b contacts 9 are connected in series is cut off. For this reason, the landing door open detection signal A is transmitted. The control panel 7 detects a failure of any of the landing door open detection devices 6 by receiving the landing door open detection signal A.

次に、図２を用いて、制御盤７の動作を説明する。
図２はこの発明の実態の形態１におけるエレベータシステムの制御盤の動作を説明するためのフローチャートである。Next, the operation of the control panel 7 will be described with reference to FIG.
FIG. 2 is a flowchart for explaining the operation of the control panel of the elevator system according to the first embodiment of the present invention.

ステップＳ１では、制御盤７は、乗場戸開検出信号Ａを受信しているか否かを判定する。ステップＳ１で制御盤７が乗場戸開検出信号Ａを受信していない場合は、ステップＳ１が繰り返される。ステップＳ１で制御盤７が乗場戸開検出信号Ａを受信している場合は、ステップＳ２に進む。   In step S1, the control panel 7 determines whether or not the landing door open detection signal A is received. If the control panel 7 does not receive the landing door open detection signal A in step S1, step S1 is repeated. If the control panel 7 has received the landing door open detection signal A in step S1, the process proceeds to step S2.

ステップＳ２では、制御盤７は、戸開許可ゾーン進入信号Ｂを受信しているか否かを判定する。   In step S2, the control panel 7 determines whether or not the door opening permission zone entry signal B is received.

ステップＳ２で制御盤７が戸開許可ゾーン進入信号Ｂを受信している場合は、ステップＳ３に進む。ステップＳ３では、制御盤７は、いずれかの乗場戸開検出装置６の故障を検出する。この際、制御盤７は、かご１の走行を禁止する。具体的には、制御盤７は、第１制動力でかご１を停止させる。その後、制御盤７は、動作を終了する。   If the control panel 7 has received the door opening permission zone entry signal B in step S2, the process proceeds to step S3. In step S <b> 3, the control panel 7 detects a failure of any landing door open detection device 6. At this time, the control panel 7 prohibits the car 1 from traveling. Specifically, the control panel 7 stops the car 1 with the first braking force. Thereafter, the control panel 7 ends the operation.

ステップＳ２で制御盤７が戸開許可ゾーン進入信号Ｂを受信していない場合は、ステップＳ４に進む。ステップＳ４では、制御盤７は、第２制動力でかご１を停止させる。例えば、第２制動力の値は、第１制動力の値よりも小さい値に設定される。その後、制御盤７は、動作を終了する。   If the control panel 7 has not received the door opening permission zone entry signal B in step S2, the process proceeds to step S4. In step S4, the control panel 7 stops the car 1 with the second braking force. For example, the value of the second braking force is set to a value smaller than the value of the first braking force. Thereafter, the control panel 7 ends the operation.

以上で説明した実施の形態１によれば、乗場戸開検出装置６は、かご１が対応階の戸開許可ゾーンに進入した際に対応した乗場戸開検出用ｂ接点９の両側を短絡させる。このため、かご１の停止階においてかご戸１ａと乗場戸１ｂとが開いている場合でも、かご１の停止階以外の階で乗場戸１ｂが開いていることを検出できる。   According to the first embodiment described above, the landing door open detection device 6 short-circuits both sides of the corresponding door open detection b-contact 9 when the car 1 enters the door opening permission zone on the corresponding floor. . For this reason, even when the car door 1a and the landing door 1b are open on the stop floor of the car 1, it can be detected that the landing door 1b is open on a floor other than the stop floor of the car 1.

また、制御盤７は、いずれかの乗場戸開検出装置６の故障を検出した際にかご１の走行を禁止する。このため、保守員が昇降路の内部に進入する際にかご１と接触することを抑制できる。   Further, the control panel 7 prohibits the traveling of the car 1 when a failure of any one of the landing door open detection devices 6 is detected. For this reason, it can suppress that a maintenance worker contacts the cage | basket | car 1 when approaching the inside of a hoistway.

また、乗場戸開検出信号Ａを受信している際に戸開許可ゾーン進入信号Ｂを受信していない場合、制御盤７は、第１制動力の値よりも小さい値に設定された第２制動力でかご１を停止させる。このため、走行中のかご１は、徐々に減速する。その結果、かご１の内部に利用者が存在する場合でも、当該利用者に過大な慣性力が作用することを抑制できる。   When the door opening permission zone entry signal B is not received when the landing door opening detection signal A is received, the control panel 7 is set to a value smaller than the value of the first braking force. The car 1 is stopped by the braking force. For this reason, the traveling car 1 is gradually decelerated. As a result, even when a user exists inside the car 1, it is possible to suppress an excessive inertial force from acting on the user.

また、複数の乗場戸開検出装置６の各々は、リレー回路で構成される。複数の乗場戸開検出装置６の各々は、対応したリレー回路が故障している際にかご１が対応階の戸開許可ゾーンに進入した場合は対応した乗場戸開検出用ｂ接点９の両側を短絡させない。この場合、対応した乗場戸１ｂが開くと、乗場戸開検出信号Ａが送信される。このため、乗場戸開検出装置６の故障を外部から診断する必要がない。その結果、最小限の構成で乗場戸開検出装置６の故障を検出することができる。   Each of the plurality of landing door open detection devices 6 is configured by a relay circuit. Each of the plurality of landing door opening detection devices 6 has both sides of the corresponding landing door opening detection b-contact 9 when the car 1 enters the door opening permission zone on the corresponding floor when the corresponding relay circuit has failed. Do not short circuit. In this case, when the corresponding landing door 1b is opened, a landing door open detection signal A is transmitted. For this reason, it is not necessary to diagnose the failure of the landing door open detection device 6 from the outside. As a result, it is possible to detect a failure of the landing door open detection device 6 with a minimum configuration.

なお、複数の複数の乗場戸開検出装置６の少なくとも一つをリレー回路で構成してもよい。この場合、当該乗場戸開検出装置６は、対応したリレー回路が故障している際にかご１が対応階の戸開許可ゾーンに進入した場合は対応した乗場戸開検出用ｂ接点９の両側を短絡させない。この場合、対応した乗場戸１ｂが開くと、乗場戸開検出信号Ａが送信される。このため、当該乗場戸開検出装置６の故障を外部から診断する必要がない。その結果、最小限の構成で当該乗場戸開検出装置６の故障を検出することができる。   Note that at least one of the plurality of landing door open detection devices 6 may be configured by a relay circuit. In this case, when the corresponding relay circuit is malfunctioning, the landing door opening detection device 6 has both sides of the corresponding contact door opening detection b contact 9 when the car 1 enters the door opening permission zone on the corresponding floor. Do not short circuit. In this case, when the corresponding landing door 1b is opened, a landing door open detection signal A is transmitted. For this reason, it is not necessary to diagnose the failure of the landing door open detection device 6 from the outside. As a result, it is possible to detect a failure of the landing door open detection device 6 with a minimum configuration.

次に、図３を用いて、制御盤７の例を説明する。
図３はこの発明の実施の形態１におけるエレベータシステムの制御盤のハードウェア構成図である。Next, an example of the control panel 7 will be described with reference to FIG.
FIG. 3 is a hardware configuration diagram of the control panel of the elevator system according to Embodiment 1 of the present invention.

制御盤７の主な機能は、処理回路により実現し得る。例えば、処理回路は、少なくとも１つのプロセッサ２５ａと少なくとも１つのメモリ２５ｂとを備える。例えば、処理回路は、少なくとも１つの専用のハードウェア２６を備える。   The main functions of the control panel 7 can be realized by a processing circuit. For example, the processing circuit includes at least one processor 25a and at least one memory 25b. For example, the processing circuit comprises at least one dedicated hardware 26.

処理回路が少なくとも１つのプロセッサ２５ａと少なくとも１つのメモリ２５ｂとを備える場合、制御盤７の主な機能は、ソフトウェア、ファームウェア、又はソフトウェアとファームウェアとの組み合わせにより実現される。ソフトウェアおよびファームウェアの少なくとも一方は、プログラムとして記述される。ソフトウェアおよびファームウェアの少なくとも一方は、少なくとも１つのメモリ２５ｂに格納される。少なくとも１つのプロセッサ２５ａは、少なくとも１つのメモリ２５ｂに記憶されたプログラムを読み出して実行することにより、制御盤７の主な機能を実現する。少なくとも１つのプロセッサ２５ａは、ＣＰＵ（Ｃｅｎｔｒａｌ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）、中央処理装置、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、ＤＳＰともいう。例えば、少なくとも１つのメモリ２５ｂは、ＲＡＭ、ＲＯＭ、フラッシュメモリ、ＥＰＲＯＭ、ＥＥＰＲＯＭ等の、不揮発性又は揮発性の半導体メモリ、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク、ＤＶＤ等である。   When the processing circuit includes at least one processor 25a and at least one memory 25b, the main function of the control panel 7 is realized by software, firmware, or a combination of software and firmware. At least one of software and firmware is described as a program. At least one of software and firmware is stored in at least one memory 25b. The at least one processor 25a realizes the main functions of the control panel 7 by reading and executing the program stored in the at least one memory 25b. The at least one processor 25a is also referred to as a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, and a DSP. For example, the at least one memory 25b is a nonvolatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

処理回路が少なくとも１つの専用のハードウェア２６を備える場合、処理回路は、例えば、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、又はこれらを組み合わせたものである。例えば、制御盤７の主な機能は、それぞれ処理回路で実現される。例えば、制御盤７の主な機能は、まとめて処理回路で実現される。   If the processing circuit comprises at least one dedicated hardware 26, the processing circuit is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. is there. For example, the main functions of the control panel 7 are each realized by a processing circuit. For example, the main functions of the control panel 7 are collectively realized by a processing circuit.

制御盤７の主な機能について、一部を専用のハードウェア２６で実現し、他部をソフトウェア又はファームウェアで実現してもよい。例えば、かご１を昇降させる機能については専用のハードウェア２６としての処理回路で実現し、かご１を昇降させる機能以外の機能については少なくとも１つのプロセッサ２５ａが少なくとも１つのメモリ２５ｂに格納されたプログラムを読み出して実行することによって実現してもよい。   Some of the main functions of the control panel 7 may be realized by the dedicated hardware 26 and the other part may be realized by software or firmware. For example, the function for raising and lowering the car 1 is realized by a processing circuit as the dedicated hardware 26, and for functions other than the function for raising and lowering the car 1, at least one processor 25a is stored in at least one memory 25b. May be realized by reading out and executing.
