When the customer power supply uninterruptive power supply detection means 7 detects the state of the interruptive power supply, the controlled private power generating operation is performed in response to the detection of the power failure by the customer power supply failure detection means. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
この発明は、客先電源の停電時にエレベータ救出用の自家発電時管制運転を行うエレベータ運転装置に関し、特に、不要な自家発電時管制運転を回避するとともに、実際の停電発生時に確実に自家発電時管制運転を実行することのできるエレベータ運転装置に関するものである。
【０００２】
【従来の技術】
従来、この種のエレベータ運転装置に用いられている自家発電時管制運転は、たとえば「エレ協標準ＪＥＡＳ−４１３」に記載されており、停電によりかご内に閉じ込められた乗客の早期救出や最小限のビル機能の維持を行うことを目的としている。
【０００３】
自家発電機の給電能力確立時に実行される具体的な運転形態としては、かご内乗客の救出のための帰着運転と、ビル内の機能維持のための継続運転とがあげられる。
【０００４】
従来のエレベータ運転装置において、停電時の自家発電時管制運転への移行は、上記「エレ協標準ＪＥＡＳ−４１３」に記載されているように、客先電源停電検出回路（接点）からの接点情報のみに頼って行われている。
【０００５】
すなわち、客先電源側に設けられた客先電源停電検出接点が一旦停電状態を検出すると、自家発電機または買電の選択を判断することなく、自家発電時管制運転に自動的に移行するようになっている。
【０００６】
しかしながら、上記従来装置のように、客先電源停電検出接点のみに依存して自家発電時管制運転を実行すると、客先電源停電検出接点が事故などにより（または、任意に）誤って遮断された場合に、エレベータ側では実際に停電が発生していないにもかかわらず、買電により自家発電時管制運転が実行されることになる。
【０００７】
このように、実際には停電でもないのに自家発電時管制運転を実行するような事態が発生すると、ビル内の縦方向の交通機関として機能するエレベータを停止させてしまうおそれがある。
【０００８】
また、近年では、停電時にエレベータから見ると無停電状態で自家発電機が供給される運転装置もあるが、エレベータ側で停電を検出する手段が設けられていないので、停電が発生しても自家発電時管制運転に移行できないおそれがある。
【０００９】
さらに、不要な自家発電時管制運転の実行を未然に防止するために、エレベータ側にもエレベータ停電検出手段を設け、エレベータ停電検出手段が停電状態を検出することにより、万一、客先電源停電検出回路が誤動作しても、不要な自家発電時管制運転を回避する装置も提案されている。
【００１０】
この場合、停電発生状態をエレベータ自身が検出し、客先電源（買電供給）の停電検出情報が何らかの原因による誤検出であっても、エレベータ側で不必要な自家発電時管制運転を実行しないように対策が施されている。
【００１１】
しかしながら、実際の停電発生時において、自家発電機が無停電で供給される装置の場合には、エレベータ側で停電検出を実行しなくなるので、自家発電時管制運転に移行することができない。
【００１２】
【発明が解決しようとする課題】
従来のエレベータ運転装置は以上のように、客先電源停電検出回路（接点情報）のみに依存して自家発電時管制運転を実行すると、客先電源停電検出回路が、事故または任意により、誤って遮断されると、エレベータ側では実際に停電が発生していないにもかかわらず、客先電源からの買電によって自家発電時管制運転を実行し、ビルの縦の交通機関であるエレベータを停止させてしまうという問題点があった。
【００１３】
また、従来のエレベータ運転装置は、エレベータ側で停電を検出していないので、停電発生時にも無停電状態で自家発電機からの電源が供給される場合には、実際に停電が発生しても検出することができず、自家発電時管制運転に移行することができないという問題点があった。
【００１４】
さらに、エレベータ停電検出手段を設けた装置においても、実際の停電発生時において、自家発電機が無停電で供給される装置の場合には、エレベータ側で停電検出を実行しなくなるので、自家発電時管制運転に移行することができないという問題点があった。
【００１５】
この発明は上記のような問題点を解決するためになされたもので、エレベータ停電検出手段および停電時客先電源無停電検出手段を設け、客先電源が誤って停電となったときに停電時客先電源無停電検出手段が動作していなければ、エレベータ停電検出手段の動作に応じて自家発電時管制運転への移行を確実に行うとともに、停電時客先電源無停電検出手段が動作していれば、客先電源停電検出手段の動作に応じて自家発電時管制運転を行うことにより、停電発生時に必要な自家発電時管制運転を確実に実行させることのできるエレベータ運転装置を得ることを目的とする。
【００１６】
【課題を解決するための手段】
この発明に係るエレベータ運転装置は、エレベータを駆動するための電力を供給する客先電源と、客先電源の停電時にエレベータの自家発電時管制運転を行うための電力を供給する自家発電機とを備え、客先電源または自家発電機から供給される電力によりエレベータを駆動させるエレベータ運転装置において、客先電源の停電状態を客先電源側で検出するための客先電源停電検出手段と、客先電源の停電状態をエレベータ側で検出するためのエレベータ停電検出手段と、客先電源の停電時に無停電状態を検出するための停電時客先電源無停電検出手段とをさらに備え、停電時客先電源無停電検出手段が無停電状態を検出していない場合には、客先電源停電検出手段およびエレベータ停電検出手段の両方が客先電源の停電状態を検出したときに自家発電時管制運転を実行し、停電時客先電源無停電検出手段が無停電状態を検出している場合には、客先電源停電検出手段が客先電源の停電状態を検出したときに自家発電時管制運転を実行するものである。
【００１７】
また、この発明に係るエレベータ運転装置は、自家発電時管制運転を行うための調整用データを格納するメモリをさらに備え、停電時客先電源無停電検出手段は、客先電源停電検出手段からの接点情報または調整用データに基づいて、無停電状態を検出するものである。
【００１８】
【発明の実施の形態】
実施の形態１．
以下、図面を参照しながら、この発明の実施の形態１について詳細に説明する。
図１はこの発明の実施の形態１を示すブロック構成図である。
【００１９】
図１において、１は検出接点からなる客先電源停電検出手段、２は買電により電力供給を行うための客先電源である。
客先電源停電検出手段１は、破線矢印で示すように、客先電源２に接続されている。客先電源２は、客先が電力会社から電力を購入して供給する電源である。
【００２０】
３は自家発電機であり、客先電源２の停電時に動作して、自家発電時管制運転を行うための電力を生成する。
４はエレベータ側に設けられたエレベータ停電検出手段であり、エレベータ側で客先電源２の停電状態を検出する。
【００２１】
エレベータ停電検出手段４は、たとえば、エレベータ制御用の（マイクロ）コンピュータを使用して構成されている。
停電発生時において、エレベータは、自家発電機３の給電能力確立時に、自家発電機３からの給電により通電される。
【００２２】
また、エレベータ停電検出手段４内のエレベータ制御用コンピュータは、自家発電機３からの給電により立上るように設定されており、エレベータ停電検出手段４は、エレベータ制御用コンピュータの立上り時に動作するパワーＯＮ（立上りフラグ）を用いて停電を検出する。
【００２３】
５は客先電源停電検出誤動作出力手段であり、客先電源停電検出手段１の誤動作が検出されたときに、その旨を外部に出力する。
６はエレベータ運転手段であり、客先電源２または自家発電機３からの供給電力を得て、エレベータの運転を行う。
【００２４】
７は停電時客先電源無停電検出手段であり、たとえば、客先電源停電検出手段１の接点情報に基づいて、停電発生時にエレベータ側に無停電で電力供給を行う「無停電状態」を検出する。
【００２５】
また、停電時客先電源無停電検出手段７は、エレベータ停電検出手段４（エレベータ制御コンピュータ）内のメモリに格納された請整用データによっても動作され得る。
【００２６】
図２は図１内のエレベータ運転装置６の処理動作の一例を示すフローチャートである。
以下、図２を参照しながら、この発明の実施の形態１による停電発生時の自家発電時管制運転の処理動作について説明する。
【００２７】
なお、図２の処理ルーチンは、エレベータ停電検出手段４無いのエレベータ制御用コンピュータが立上ると、起動されてから所定の周期Ｔで実行される。
【００２８】
たとえば、客先電源２から電力が供給されて平常運転を実行中に停電が発生した場合、自家発電機３が確立したとすると、エレベータに自家発電機３から電力が通電される。
【００２９】
このとき、停電時客先電源無停電検出７が動作していなければ、エレベータは、一時的に停電となった後で、自家発電機３からの通電により給電され、エレベータ停電検出手段４内のエレベータ制御用コンピュータが立上る。
【００３０】
図２において、まず、停電時客先電源無停電検出手段７による「停電時客先電源無停電検出」が有りか否かを判定する（ステップＳ１ａ）。
この時点では、まだ停電時客先電源無停電検出手段７が動作していないので、「停電時客先電源無停電検出」が無し（すなわち、ＮＯ）と判定され、ステップＳ１に進む。
【００３１】
ステップＳｌにおいては、エレベータ停電検出手段４内の「エレベータ制御用コンピュータ立上りフラグＦｃ」がＯＦＦか否かを判定する。
この時点では、まだ、立上りフラグＦｃがＯＦＦであるので、Ｆｃ＝０（すなわち、ＹＥＳ）と判定され、ステップＳ２に進む。
【００３２】
ステップＳ２においては、自家発電機３が立上り状態にあることから、エレベータ制御用コンピュータ立上りフラグＦｃが「１」に設定される。
また、ステップＳ３において、エレベータ停電検出フラグＦｄが「１」に設定される。
【００３３】
こうして、ステップＳ２、Ｓ３により、各フラグＦｃおよびＦｄは、「ＯＦＦ（＝０）」から「ＯＮ（＝１）」に移行する。
【００３４】
その後、上記所定周期Ｔで実行されるサイクル処理において、ステップＳ１の「エレベータ制御用コンピュータ立上りフラグＦｃ」がＯＦＦか否かの判定処理は、Ｆｃ＝１（ＯＮ）（すなわち、ＮＯ）と判定されるので、ステップＳ４に進む。
【００３５】
ステップＳ４においては、「エレベータ制御用コンピュータ立上りフラグＦｃ」の設定後に、所定時間「１分以上」が経過したか否かを判定し、１分以上が経過していない（すなわち、ＮＯ）と判定されれば、ステップＳ７に進む。
【００３６】
なお、ここでは、所定時間を「１分以上」に設定しているが、「１分」という時間に限定されるものではなく、任意の時間にあらかじめ定められているものとする。
【００３７】
ステップＳ７においては、客先電源停電検出手段１が停電を検出したか否かを判定し、停電検出していない（すなわち、ＮＯ）と判定されれば、平常運転を指令して（ステップＳ１１）、図２の処理ルーチンを終了する。
【００３８】
この場合は、停電が発生した場合を例にとっており、客先電源停電検出手段１が停電状態を検出しているので、ステップＳ７において、停電検出した（すなわち、ＹＥＳ）と判定され、ステップＳ８に進む。
【００３９】
ステップＳ８においては、エレベータ停電検出フラグＦｄはＯＮか否かを判定する。この場合、エレベータ停電検出フラグＦｄがＯＮされているので、Ｆｄ＝１（すなわち、ＹＥＳ）と判定される。
【００４０】
したがって、ステップＳ９に進み、エレベータ制御用コンピュータは、自家発電機３からの給電による自家発電時管制運転を指令して、図２の処理ルーチンを終了する。
【００４１】
その後、自家発電機３の立上り後から１分間経過すると、ステップＳ４において、エレベータ制御用コンピュータ立上りフラグＦｃの設定後に１分間経過した（すなわち、ＹＥＳ）と判定され、ステップＳ５、Ｓ６に進む。
【００４２】
ステップＳ５およびＳ６において、エレベータ制御用コンピュータ立上りフラグＦｃおよびエレベータ停電検出フラグＦｄは、ＯＮ状態「１」からＯＦＦ状態「０」にリセットされ、図２の処理ルーチンを終了する。
【００４３】
次に、実際の停電ではなく客先電源２が正常の場合に、客先電源停電検出手段１の電源を誤って遮断したときに、平常運転を継続させる場合の処理動作の一例について説明する。
【００４４】
この場合、停電時客先電源無停電検出手段７が動作していないので、まず、ステップＳ１ａにおいて、停電時客先電源無停電検出が無い（すなわち、ＮＯ）と判定され、ステップＳ１に進む。
【００４５】
このとき、エレベータ制御用コンピュータの立上りフラグＦｃがＯＮにセットされているので、ステップＳ１において、Ｆｃ＝１（すなわち、ＮＯ）と判定され、ステップＳ４に進む。
【００４６】
ステップＳ４においては、フラグＦｃの設定後に１分以上が経過していない（すなわち、ＮＯ）と判定されるので、ステップＳ７の判定処理（客先電源停電検出手段１が停電検出したか否か）に進む。
【００４７】
この場合、客先電源２が実際には停電でないにもかかわらず、客先電源停電検出手段１の電源が誤って遮断されているので、ステップＳ７において、停電検出した（すなわち、ＹＥＳ）と判定され、ステップＳ８に進む。
【００４８】
この場合、エレベータ停電検出手段４は「停電でない状態」を検出しており、エレベータ停電検出フラグＦｄはＯＦＦされているので、ステップＳ８においては、Ｆｄ＝０（すなわち、ＮＯ）と判定され、客先電源停電検出手段１が誤動作したことが明確となる。
【００４９】
続いて、ステップＳ１ｂに進み、停電時客先電源無停電検出手段７による無停電検出があるか否かを判定し（ステップＳ１ｂ）、無停電検出が無い（すなわち、ＮＯ）と判定される。
【００５０】
したがって、エレベータ外部に客先電源停電検出手段１が誤動作していることを出力するとともに（ステップＳ１０）、当然のことながら、自家発電時管制運転に移行せずに平常運転を継続するための指令を行い（ステップＳ１１）、図２の処理ルーチンを終了する。
【００５１】
最後に、自家発電時管制運転の成立時において、エレベータに対して無停電で自家電源機３からの電源が供給される場合について説明する。
まず、問題点を明確化するために、仮に、ステップＳ１ａにおいて、無停電検出が無い（すなわち、ＮＯ）と判定され、続いて、ステップＳ１において、Ｆｃ＝１（すなわち、ＮＯ）と判定され、ステップＳ４に進んだ場合を想定する。
【００５２】
ステップＳ４においては、エレベータ制御用コンピュータ立上りフラグＦｃの設定後に１分以上が経過していない（すなわち、ＮＯ）と判定されるので、ステップＳ７に進む。
【００５３】
ステップＳ７においては、客先電源停電検出手段１は停電検出している（すなわち、ＹＥＳ）と判定されるので、ステップＳ８に進む。
ステップＳ８においては、エレベータ停電検出フラグＦｄがＯＮされていないので、Ｆｄ＝０（すなわち、ＮＯ）と判定される。
【００５４】
このとき、直ちにステップＳ１１に進んだと仮定すると、結果的に客先電源２が停電したにもかかわらず、エレベータが平常運転されるので、自家発電機３の容量不足からストールが発生して、停電発生による緊急時に閉じ込め事故が発生することになる。
【００５５】
次に、ステップＳ１ａを考慮しながら、この発明の実施の形態１による自家発電時管制運転成立時に無停電給電される場合の処理動作について説明する。
まず、停電時において無停電で自家発電機３からの電力が供給されることが、客先情報として停電時客先電源無停電検出手段７に入力されているので、ステップＳ１ａにおいて、停電時客先電源無停電検出が有り（すなわち、ＹＥＳ）と判定されるので、ステップＳ７に進む。
【００５６】
ステップＳ７においては、客先電源停電検出手段１が停電検出している（すなわち、ＹＥＳ）と判定されるので、ステップＳ８に進む。
ステップＳ８においては、エレベータ停電検出手段１が停電検出していないので、Ｆｄ＝０（すなわち、ＮＯ）と判定される。
【００５７】
このとき、上記問題が発生するかのように思えるが、続いて、ステップＳ１ｂにおいて、停電時客先電源無停電検出手段７による無停電検出の有無が再度判定されて、無停電検出が有り（すなわち、ＹＥＳ）と判定されるので、ステップＳ９に進み、必要な自家発電時管制運転を確実に行うことができる。
【００５８】
このように、客先電源２側で停電検出する客先電源停電検出手段１と、客先電源２の停電時にエレベータ管制運転用の電力を供給する自家発電機３と、エレベータ側で停電検出するエレベータ停電検出手段４と、エレベータ運転手段６と、停電時の無停電給電を検出する停電時客先電源無停電検出手段７とを設け、停電時客先電源無停電検出手段７の動作の有無を参照して、自家発電時管制運転（ステップＳ９）を実行する。
【００５９】
すなわち、停電発生時に、停電時客先電源無停電検出手段７が動作していない場合には、エレベータ停電検出手段４の動作の有無に応じて自家発電時管制運転（ステップＳ９）を行い、停電時客先電源無停電検出手段７が動作している場合には、客先電源停電検出手段１の動作の有無に応じて自家発電時管制運転を行うことができる。
【００６０】
すなわち、客先電源停電検出手段１のみならず、エレベータ停電検出手段４でも停電状態を検出することにより、万一、客先電源停電検出手段１が誤動作した場合にも、不要な自家発電時管制運転の実行を未然に防止することができる。
【００６１】
停電時に自家発電機３が無停電給電する装置において、エレベータ停電検出手段４が停電検出を実行しなくても、停電時客先電源無停電検出手段７により無停電検出するので、自家発電時管制運転を必要とする場合には、確実に自家発電時管制運転を実行することができる。
【００６２】
なお、上記実施の形態１においては、客先電源２の検出情報を停電時客先電源無停電検出手段７に入力して、自家発電機３の無停電給電状態を検出する場合を示したが、エレベータ停電検出手段４（エレベータ制御コンピュータ）内のメモリデータとして、自家発電機３が無停電で供給される請整用データを保持し、調整用データから無停電給電状態を検出しても同等の作用効果を奏する。
【００６３】
また、上記実施の形態１では、エレベータの台数について特に言及しなかったが、複数のエレベータを制御する詳管理方式のエレベータ運転装置に適用しても同等の作用効果を奏することは言うまでもない。
【００６４】
【発明の効果】
以上のように、この発明によれば、エレベータを駆動するための電力を供給する客先電源と、客先電源の停電時にエレベータの自家発電時管制運転を行うための電力を供給する自家発電機とを備え、客先電源または自家発電機から供給される電力によりエレベータを駆動させるエレベータ運転装置において、客先電源の停電状態を客先電源側で検出するための客先電源停電検出手段と、客先電源の停電状態をエレベータ側で検出するためのエレベータ停電検出手段と、客先電源の停電時に無停電状態を検出するための停電時客先電源無停電検出手段とをさらに備え、停電時客先電源無停電検出手段が無停電状態を検出していない場合には、客先電源停電検出手段およびエレベータ停電検出手段の両方が客先電源の停電状態を検出したときに自家発電時管制運転を実行し、停電時客先電源無停電検出手段が無停電状態を検出している場合には、客先電源停電検出手段が客先電源の停電状態を検出したときに自家発電時管制運転を実行するようにしたので、停電発生時に必要な自家発電時管制運転を確実に実行させることのできるエレベータ運転装置が得られる効果がある。
【００６５】
また、この発明によれば、自家発電時管制運転を行うための調整用データを格納するメモリをさらに備え、停電時客先電源無停電検出手段は、客先電源停電検出手段からの接点情報または調整用データに基づいて、無停電状態を検出するようにしたので、停電発生時に必要な自家発電時管制運転を確実に実行させることのできるエレベータ運転装置が得られる効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator operation device that performs a control operation at the time of a private power generation for rescue of an elevator at the time of a power outage at a customer's power supply, and in particular, avoids unnecessary control operation at a time of an in-house power generation, and ensures that an automatic power generation at the time of an actual power failure occurs. The present invention relates to an elevator operation device capable of performing a control operation.
[0002]
[Prior art]
Conventionally, the control operation at the time of private power generation used in this type of elevator operation device is described in, for example, “Elevator Standard JEAS-413”, and the early rescue and minimal rescue of passengers trapped in a car due to a power failure. The purpose of this project is to maintain the building functions.
[0003]
Specific operation modes executed when the power supply capacity of the private generator is established include a return operation for rescuing passengers in the car and a continuous operation for maintaining functions in the building.
[0004]
In the conventional elevator operation device, the transition to the control operation at the time of private power generation at the time of a power failure is performed by contact information from a customer power supply failure detection circuit (contact) as described in the above-mentioned "Elekyo Standard JEAS-413". Only relying on it.
[0005]
That is, once the customer power source power failure detection contact provided on the customer power source side detects the power failure state, the control automatically shifts to the private power generation control operation without judging the selection of the private power generator or the power purchase. It has become.
[0006]
However, when the self-power-generation control operation is performed only depending on the customer power failure detection contact as in the conventional device described above, the customer power failure detection contact is accidentally shut off due to an accident or the like (or arbitrarily). In this case, the self-power-generation control operation is executed by the power purchase even though the power failure has not actually occurred on the elevator side.
[0007]
As described above, if a situation occurs in which the control operation is performed during the private power generation even when there is no actual power outage, there is a possibility that the elevator functioning as a vertical transportation in the building may be stopped.
[0008]
Also, in recent years, there is an operating device in which a private power generator is supplied in an uninterrupted state when viewed from an elevator at the time of a power failure.However, since a means for detecting a power failure is not provided on the elevator side, even if a power failure occurs, a private power generator can be provided. It may not be possible to shift to control operation during power generation.
[0009]
Further, in order to prevent unnecessary execution of the control operation at the time of private power generation, an elevator power outage detecting means is also provided on the elevator side, and the elevator power outage detecting means detects a power outage state. Even if the detection circuit malfunctions, a device that avoids unnecessary control operation at the time of private power generation has been proposed.
[0010]
In this case, the elevator itself detects the power failure occurrence state, and does not execute the unnecessary self-power generation control operation on the elevator side even if the power failure detection information of the customer power supply (power purchase supply) is erroneous detection due to some cause. Measures have been taken.
[0011]
However, when an actual power failure occurs, if the private power generator is a device that is supplied without power failure, the power failure detection is not performed on the elevator side, so that it is not possible to shift to the private power generation control operation.
[0012]
[Problems to be solved by the invention]
As described above, when the conventional elevator operating device executes the control operation at the time of the private power generation only depending on the customer power supply outage detection circuit (contact information), the customer power supply outage detection circuit may When the power is shut off, the elevator side executes the control operation during private power generation by purchasing power from the customer's power supply, and stops the elevator, which is the vertical transportation system of the building, even though no actual power outage has occurred. There was a problem that would.
[0013]
In addition, the conventional elevator operation device does not detect a power failure on the elevator side, so even when a power failure occurs, if power is supplied from the private generator in an uninterrupted state even if a power failure occurs, There was a problem that it was not possible to detect it, and it was not possible to shift to the control operation during private power generation.
[0014]
Further, even in a device provided with an elevator power failure detection means, when an actual power failure occurs, if the private power generator is a device that is supplied without interruption, the power failure detection is not performed on the elevator side. There was a problem that it was not possible to shift to control operation.
[0015]
The present invention has been made in order to solve the above-described problems, and provides an elevator power failure detection means and a customer power supply uninterruptible power detection means at the time of power failure, so that when a customer power supply is erroneously powered out, a power failure occurs. If the customer power source uninterruptible power detection means is not operating, the shift to the private power generation control operation is reliably performed in accordance with the operation of the elevator power outage detection means, and the customer power source uninterruptible power detection means during power outage is operating. Accordingly, an object of the present invention is to provide an elevator operation device capable of reliably performing a self-power generation control operation required when a power failure occurs by performing a self-power generation control operation according to the operation of a customer power supply power failure detection unit. And
[0016]
[Means for Solving the Problems]
An elevator operating device according to the present invention includes a customer power supply that supplies electric power for driving an elevator, and a private power generator that supplies electric power for performing self-powered control operation of the elevator when the customer power supply fails. An elevator operating device for driving an elevator by electric power supplied from a customer power supply or a private power generator, wherein a customer power supply power failure detection means for detecting a customer power supply power failure state on the customer power supply side; An elevator power outage detecting means for detecting a power outage state on the elevator side; and a power outage customer power supply uninterruptible power detecting means for detecting an uninterruptible state in the event of a customer power outage. When both the customer power outage detection means and the elevator power outage detection means detect the power outage state of the customer power supply when the power uninterruptibility detection means does not detect the uninterruptible state. When the self-power generation control operation is performed and the customer power supply uninterruptible power detection unit detects an uninterruptible state during a power outage, the customer The control operation at the time of power generation is executed.
[0017]
Further, the elevator operating device according to the present invention further includes a memory for storing adjustment data for performing the control operation at the time of private power generation, and the uninterruptible customer power source detecting means at the time of power failure is provided from the customer power source power failure detecting means. The uninterruptible power state is detected based on the contact information or the adjustment data.

In FIG. 1, reference numeral 1 denotes a customer power outage detecting means including a detection contact, and reference numeral 2 denotes a customer power supply for supplying power by purchasing power.
The customer power supply outage detecting means 1 is connected to the customer power supply 2 as shown by a dashed arrow. The customer power supply 2 is a power supply that the customer purchases and supplies power from a power company.
[0020]
Reference numeral 3 denotes a private power generator, which operates when the customer power supply 2 is out of power, and generates electric power for performing the private power generation control operation.
Reference numeral 4 denotes an elevator power failure detection means provided on the elevator side, which detects a power failure state of the customer power supply 2 on the elevator side.
[0021]
The elevator power failure detection means 4 is configured using, for example, a (micro) computer for elevator control.
When a power failure occurs, the elevator is energized by power supply from the private generator 3 when the power supply capability of the private generator 3 is established.
[0022]
The elevator control computer in the elevator power outage detecting means 4 is set so as to start up by the power supply from the private power generator 3. The power failure is detected using the (rising flag).
[0023]
Reference numeral 5 denotes a customer power outage detection malfunction operation output unit. When a malfunction of the customer power outage detection unit 1 is detected, the malfunction is output to the outside.
Numeral 6 denotes an elevator operating means, which obtains power supplied from the customer power supply 2 or the private power generator 3 to operate the elevator.
[0024]
Reference numeral 7 denotes a customer power supply uninterruptible power detecting means at the time of a power outage. For example, based on contact information of the customer power outage detecting means 1, a "uninterruptible state" for supplying power to the elevator side without power outage when a power outage occurs is detected. I do.
[0025]
In addition, the customer power source uninterruptible power detection means 7 at the time of power failure can also be operated based on adjustment data stored in a memory in the elevator power failure detection means 4 (elevator control computer).
[0026]
FIG. 2 is a flowchart showing an example of the processing operation of the elevator operating device 6 in FIG.
Hereinafter, the processing operation of the self-power-generation control operation at the time of a power failure according to the first embodiment of the present invention will be described with reference to FIG.
[0027]
Note that the processing routine of FIG. 2 is executed at a predetermined cycle T after being started when the elevator control computer without the elevator power failure detection means 4 starts up.
[0028]
For example, if a power failure occurs during normal operation with power supplied from the customer's power supply 2 and the private power generator 3 is established, power is supplied from the private power generator 3 to the elevator.
[0029]
At this time, if the customer power supply uninterruptible power detection 7 during power outage is not operating, the elevator is temporarily supplied with power from the private power generator 3 after a power outage, and the elevator power outage detection means 4 The elevator control computer starts up.
[0030]
In FIG. 2, first, it is determined whether or not there is “customer power source uninterruptible power failure detection” by the power outage customer power source uninterruptible power detector 7 (step S1a).
At this time, since the power-failure customer power source uninterruptible power detection means 7 has not yet been operated, it is determined that "no power-failure customer power source uninterruptible power detection" is not present (that is, NO), and the process proceeds to step S1.
[0031]
In step Sl, it is determined whether or not the “elevator control computer rising flag Fc” in the elevator power failure detection means 4 is OFF.
At this time, since the rising flag Fc is still OFF, it is determined that Fc = 0 (that is, YES), and the process proceeds to step S2.
[0032]
In step S2, since the private generator 3 is in the rising state, the computer control flag Fc for elevator control is set to "1".
In step S3, the elevator power outage detection flag Fd is set to "1".
[0033]
Thus, in steps S2 and S3, the flags Fc and Fd shift from “OFF (= 0)” to “ON (= 1)”.
[0034]
Thereafter, in the cycle processing executed in the predetermined cycle T, the determination processing of whether or not the “elevator control computer rising flag Fc” in step S1 is OFF is determined as Fc = 1 (ON) (that is, NO). Therefore, the process proceeds to step S4.
[0035]
In step S4, it is determined whether or not a predetermined time "one minute or more" has elapsed after the setting of the "elevator control computer rising flag Fc", and it is determined that one minute or more has not elapsed (ie, NO). If so, the process proceeds to step S7.
[0036]
Here, the predetermined time is set to “1 minute or more”, but the time is not limited to “1 minute”, and is set to an arbitrary time in advance.
[0037]
In step S7, it is determined whether or not the customer's power failure detection means 1 has detected a power failure. If it is determined that no power failure has been detected (ie, NO), normal operation is commanded (step S11). Then, the processing routine of FIG. 2 ends.
[0038]
In this case, a case where a power failure has occurred is taken as an example, and since the customer power supply failure detection means 1 has detected a power failure state, it is determined in step S7 that a power failure has been detected (ie, YES), and the process proceeds to step S8. move on.
[0039]
In step S8, it is determined whether the elevator power failure detection flag Fd is ON. In this case, since the elevator power failure detection flag Fd is ON, it is determined that Fd = 1 (that is, YES).
[0040]
Accordingly, the process proceeds to step S9, where the elevator control computer instructs the control operation at the time of private power generation by power supply from the private power generator 3, and ends the processing routine of FIG.
[0041]
Thereafter, when one minute has elapsed after the rise of the private generator 3, it is determined in Step S4 that one minute has elapsed after the setting of the elevator control computer rising flag Fc (that is, YES), and the process proceeds to Steps S5 and S6.
[0042]
In steps S5 and S6, the elevator control computer rising flag Fc and the elevator power failure detection flag Fd are reset from the ON state “1” to the OFF state “0”, and the processing routine of FIG. 2 ends.
[0043]
Next, an example of the processing operation in the case where the normal operation is continued when the power supply of the customer power supply failure detecting means 1 is erroneously cut off when the customer power supply 2 is normal but not the actual power failure will be described.
[0044]
In this case, since the power-failure-time customer power source uninterruptible power detection means 7 is not operating, first, in step S1a, it is determined that there is no power-failure-time customer power source no power failure detection (that is, NO), and the process proceeds to step S1.
[0045]
At this time, since the rising flag Fc of the elevator control computer is set to ON, it is determined that Fc = 1 (that is, NO) in step S1, and the process proceeds to step S4.
[0046]
In step S4, since it is determined that one minute or more has not elapsed after the setting of the flag Fc (that is, NO), the determination processing of step S7 (whether the power failure detection means 1 detects a power failure). Proceed to.
[0047]
In this case, although the customer power supply 2 is not actually a power failure, the power supply of the customer power failure detection means 1 is erroneously shut off, so it is determined that a power failure has been detected (ie, YES) in step S7. Then, the process proceeds to step S8.
[0048]
In this case, since the elevator power failure detection means 4 has detected the "non-power failure state" and the elevator power failure detection flag Fd has been turned off, it is determined that Fd = 0 (that is, NO) in step S8, It becomes clear that the preceding power failure detection means 1 malfunctioned.
[0049]
Subsequently, the process proceeds to step S1b, where it is determined whether or not there is an uninterruptible power detection by the customer power source uninterruptible power outage detecting means 7 during a power outage (step S1b), and it is determined that there is no uninterruptible power detection (that is, NO).
[0050]
Therefore, the fact that the customer power outage detecting means 1 is malfunctioning is output to the outside of the elevator (step S10), and naturally, the command for continuing the normal operation without shifting to the self-power generation control operation is output. (Step S11), and the processing routine of FIG. 2 ends.
[0051]
Lastly, a case will be described in which power is supplied from the private power supply unit 3 to the elevator without interruption when the private power generation control operation is established.
First, in order to clarify the problem, it is temporarily determined that there is no uninterruptible power detection (that is, NO) in step S1a, and then it is determined that Fc = 1 (that is, NO) in step S1. It is assumed that the process has proceeded to step S4.
[0052]
In step S4, it is determined that one minute or more has not elapsed after the setting of the elevator control computer rising flag Fc (that is, NO), and the process proceeds to step S7.
[0053]
In step S7, since it is determined that the power failure detection means 1 has detected a power failure (that is, YES), the process proceeds to step S8.
In step S8, since the elevator power failure detection flag Fd has not been turned ON, it is determined that Fd = 0 (that is, NO).
[0054]
At this time, assuming that the process has immediately proceeded to step S11, the elevator is operated normally even though the customer's power supply 2 is cut off, and a stall occurs due to a shortage of capacity of the private generator 3, A confinement accident will occur in an emergency due to a power outage.
[0055]
Next, a processing operation in the case where uninterruptible power supply is performed when the self-power-generation control operation is established according to the first embodiment of the present invention will be described in consideration of step S1a.
First, since the fact that the power from the private power generator 3 is supplied without interruption during a power failure is input as customer information to the customer power source uninterruptible power detection means 7 at the time of power failure, in step S1a, the customer Since it is determined that the uninterruptible power source detection has been performed (that is, YES), the process proceeds to step S7.
[0056]
In step S7, since it is determined that the power failure detection means 1 has detected a power failure (that is, YES), the process proceeds to step S8.
In step S8, it is determined that Fd = 0 (that is, NO) because the elevator power failure detection means 1 has not detected a power failure.
[0057]
At this time, it seems as if the above-mentioned problem occurs, but subsequently, in step S1b, the presence or absence of the uninterruptible power detection by the uninterruptible power source at the power outage detecting means 7 is determined again, and the uninterruptible power is detected ( That is, since it is determined as YES), the process proceeds to step S9, and the necessary self-power generation control operation can be reliably performed.
[0058]
As described above, the customer power supply power failure detection means 1 for detecting the power failure on the customer power supply 2 side, the private power generator 3 for supplying the power for the elevator control operation when the customer power supply 2 fails, and the power failure detection on the elevator side. Elevator power outage detecting means 4, elevator operating means 6, and power outage customer power source uninterruptible power detecting means 7 for detecting uninterrupted power supply during power outage are provided. , The in-house power generation control operation (step S9) is executed.
[0059]
In other words, when the power failure occurs, the customer power supply uninterruptible power failure detection means 7 during power failure is not operating, and the self-power generation control operation (step S9) is performed according to whether the elevator power failure detection means 4 is operating or not. When the customer power supply uninterruptible power detection means 7 is operating, the self-power generation control operation can be performed depending on whether the customer power supply power outage detection means 1 is operating.
[0060]
That is, not only the customer power outage detection means 1 but also the elevator power outage detection means 4 detects the power outage state. Execution of operation can be prevented beforehand.
[0061]
In a device in which the private power generator 3 supplies uninterrupted power during a power outage, even if the elevator power outage detecting means 4 does not execute power outage detection, the power outage customer power source uninterruptible power detecting means 7 detects uninterrupted power. When operation is required, the self-power generation control operation can be reliably performed.
[0062]
In the first embodiment, the case where the detection information of the customer power supply 2 is input to the customer power supply uninterruptible power detection means 7 at the time of power failure to detect the uninterruptible power supply state of the private generator 3 has been described. Even if the private power generator 3 holds the data for uninterruptible power supply as the memory data in the elevator power outage detecting means 4 (elevator control computer) and detects the uninterruptible power supply state from the adjustment data, It has the function and effect of.
[0063]
Further, in the first embodiment, the number of elevators is not particularly described, but it goes without saying that the same operation and effect can be obtained even when applied to an elevator operating device of a detailed management system for controlling a plurality of elevators.
[0064]
【The invention's effect】

[0065]
