Description

【０００１】
【発明の属する技術分野】
本発明は、エレベータの防犯運転方法に係り、特に、防犯運転を設定することにより乗かごを利用した犯罪を防止するエレベータの防犯運転方法に関する。
【０００２】
【従来の技術】
エレベータ利用客のかご呼びを優先する運転種類として、いわゆる専用運転とかご呼び優先運転とがある。専用運転は会社幹部などの重要人物が階床間移動をスムーズに実施するため、専用運転切替スイッチの操作により乗場呼びに応答せずにかご呼びで登録された目的階に乗かごを直接走行させるものである。また、かご呼び優先運転は宿泊施設等で利用客同士が顔を合わせることを回避するため、常時かご呼び優先運転を行い、乗かごが走行中に乗場呼びが登録されても応答せず、かご呼びで登録された目的階へ直接走行させ、かご呼びの登録の消磁に応じて先に登録された乗場呼びに応答するものである。
【０００３】
そして、従来、このような専用運転およびかご呼び優先運転を防犯運転装置として適用している。すなわち、マンション等の集合住宅に住んでいる女性が夜間外出から帰り自宅のある階床までエレベータを利用する際、見知らぬ不審者と乗かごに同乗しないように、通常外部と出入口を介してつながっている１階床で乗場の周囲を見渡し、誰もいないことを確認してからエレベータを利用している。１階床の安全を確認して乗かごに乗込んでも、通常運転では１階床と階段で行き来できる、例えば２階床から不審者が乗かごに乗り込んでくる可能性があったが、前述したような専用運転やかご呼び優先運転を実施することにより、他階床の乗場呼びを利用して不審者が乗かごを停止させ、乗込んでくることを防ぐことができる。
【０００４】
従来、この種の防犯運転装置として、乗場にカードリーダを設置し、このカードリーダにカードを読ませることにより専用運転を実施するものがある。（例えば、特許文献１参照。）。
【０００５】
また、ビルの出入口階を除くいずれかの階床に侵入者が侵入したことを検出して監視センタに通報するとともに、複数の階床の乗場呼びおよび乗かご内のかご呼びを無効にして侵入者のエレベータの利用を阻止し、かつ出入り口階に直行運転した乗かごに駆けつけた警備員が乗り込み、専用運転スイッチを操作して乗場呼びおよびかご呼びを有効として侵入者の侵入した階床に素早く到達できるようにするエレベータの運転装置がある。（例えば、特許文献２参照。）。

（２頁右下欄１１行目−３頁右上欄１５行目、第１図）
【０００７】
【特許文献２】
特開平７−５３１５３号公報
（段落番号００１６−００１９、第１図）
【０００８】
【発明が解決しようとする課題】
ところで、前者の特開平２−２０４２８３公報に記載のものでは、カードをカードリーダに挿入することにより目的階まで専用運転を行い、到着後専用運転が解除され乗場呼びが有効になる。しかし、先の利用者の利用階床、すなわち目的階は、乗かごの走行時間により比較的簡単に判明する。このため例えば利用者の少ない夜間にカード所有者が専用運転で目的階へ出発した後、不審者は乗かごの走行時間からカード所有者の目的階を割り出し、乗場で乗場呼びを登録し続け、専用運転終了後に乗場呼びに応答した乗かごに乗り込み、対象となる目的階に移動することが可能であった。また、この防犯運転装置にあっては、かご位置表示灯のかご位置により先の利用者の目的階を割り出すことを防止するため、専用運転に応じて乗場呼びが有効となるまでかご位置を非表示としているが、先の利用者の目的階の割り出しを防止する反面、他の利用者がエレベータの故障と勘違いする恐れがあった。
【０００９】
また、後者の特開平７−５３１５３号公報に記載のものは、侵入者の侵入した階床に警備員等が素早く到達できるようにするものであるが、侵入者の侵入後にエレベータの利用を阻止するものであり、防犯運転装置として、先の利用者の目的階を不審者が知り、この利用者の利用後、エレベータに乗り込み、対象となる目的階へ移動することを防止することはできない。
【００１０】
本発明はこのような従来技術における実情に鑑みてなされたもので、その目的は、不審者が先の利用者の目的階にエレベータを利用して移動することを防ぐことのできるエレベータの防犯運転装置を提供することにある。
【００１１】
【課題を解決するための手段】
この目的を達成するために本発明は、乗場に設置された乗場釦の操作により乗場呼びを登録し乗かごを呼び寄せるとともに、乗かご内に設置されるかご呼び釦の操作によりかご呼びを登録し目的階へ乗かごを走行させるエレベータにあって、防犯運転を設定することにより前記乗かごを利用した犯罪を防止するエレベータの防犯運転方法において、乗場および乗かご内の少なくとも一方に設けられた設定手段の操作に応じて、前記かご呼びの登録から前記乗かごの目的階への到着まで前記乗場呼びを無効とする第１の工程、および前記設定手段の操作から所定時間、前記乗かごが目的階へ到着した後も継続して前記乗場呼びを無効とする第２の工程から成る防犯運転が設定されるようにしてある。
【００１２】
本発明によれば、利用者が設定手段を操作することにより、利用者によるかご呼びの登録から乗かごの目的階への到着まで乗場呼びは無効となる。これにより不審者が他の階床で乗場呼びを登録して乗かごを停止させ、乗かごに乗り込むことを防ぐ。また、乗かごは目的階に到着後も所定時間、継続して乗場呼びは無効となる。これにより不審者が乗場呼びを登録し続けても目的階に着床した乗かごは乗場呼びにすぐに応答することがなく、したがって先の利用者を不審者がエレベータを利用して後から追いかけることを防ぐことができる。
【００１３】
【発明の実施の形態】
以下、本発明のエレベータの防犯運転方法の実施の形態を図に基づいて説明する。
【００１４】

【００１５】

一端が電源Ｐに接続される防犯運転回路２の常閉接点２ｂ４と、一端が常閉接点２ｂ４、他端が電源Ｎに接続される音声ガイダンス回路１４と、一端が電源Ｐに接続される防犯運転回路２の常開接点２ａ４と、一端が常開接点２ａ４に接続され、乗かご基準階検出回路８による乗かごの基準階着床の検出に応じて閉路する常開接点８ａ３と、一端が常開接点８ａ３、他端が電源Ｎに接続される戸閉タイミング回路１５と、一端が電源Ｐに接続される防犯運転回路２の常開接点２ａ５と、一端が常開接点２ａ５に接続され、乗かご内に設けられる第２の設定手段１６と、一端が第２の設定手段１６、他端が電源Ｎに接続され、乗かごを目的階と異なる最寄階に走行させる最寄階走行回路１７と、一端が電源Ｐに接続される防犯運転回路２の常開接点２ａ６と、一端が常開接点２ａ６に接続され、乗かご内に設けられる第３の設定手段１８と、一端が第３の設定手段１８、他端が電源Ｎに接続され、乗かごを最寄階に停止させる最寄階停止回路１９と、一端が電源Ｐに接続される防犯運転回路２の常開接点２ａ７と、一端が常開接点２ａ７に接続され、乗かご基準階検出回路８による乗かごの基準階着床の検出に応じて閉路する常開接点８ａ４と、一端が常開接点８ａ４、他端が電源Ｎに接続され、かごドアおよび乗場ドアの開扉を無効とする再戸開無効回路２０とを備えている。
【００１６】
なお、図１には３階床のかご呼びを登録するかご呼び釦５３、および４階床のかご呼びを登録するかご呼び釦５４の記載が便宜上省略されているが、乗かご内に前記のものが備えられていることはもちろんである。また、２階床の乗場に設置される上昇乗場呼び釦７２ｕ、および３階床の乗場に設置される上昇乗場呼び釦７３ｕの記載が便宜上省略されているが、それぞれの乗場に前記のものが備えられていることはもちろんである。さらに、３階床の乗場に設置される下降乗場呼び釦７３ｄ、および４階床の乗場に設置される下降乗場呼び釦７４ｄの記載が便宜上省略されているが、それぞれの乗場に前記のものが備えられていることはもちろんである。
【００１７】
この実施形態にあっては、通常時、利用者が乗場呼び釦７１ｕ〜７５ｄのいずれかを操作して乗場呼びを登録すると乗場呼び運転回路７が動作し、乗かごを該階床へ移動させ、次いで、利用者は乗かごに乗り込み、かご呼び釦５１〜５５のいずれかを操作してかご呼びを登録し、これに応じてかご呼び運転回路５が動作し、目的階へ乗かごを走行させる。
【００１８】
本実施形態では、例えば２０：００から６：００の所定時間帯になると防犯運転設定時計１０が動作し、常開接点１０ａが閉路する。この時間帯に利用者が設定手段１を操作すると、電源Ｐ−設定手段１−常開接点１０ａ−防犯運転回路２−電源Ｎの回路が形成され、防犯運転回路２が動作し、常閉接点２ｂ１、２ｂ２が開路して乗場呼び運転回路７が無効となり、かご呼び運転回路５だけが有効となる。また、このとき常開接点２ａ１が閉路することにより、電源Ｐ−常開接点２ａ１−常閉接点３ｂ−常閉接点４ｂ−防犯運転回路２−電源Ｎの回路が形成され、防犯運転回路２が自己保持されるとともに、電源Ｐ−常開接点２ａ１−防犯運転継続タイマ３−電源Ｎの回路が形成され、防犯運転継続タイマ３が計測を開始する。防犯運転が設定されると、その開始から解除まで乗場呼びが無効となり、他の利用者の乗場呼びによるエレベータ利用が不可能となる。この防犯運転継続タイマ３の時限は、設定手段１が設置される１階床から最上階である５階床までの乗かごの往復走行に要する時間以上に設定されており、他の利用者はその間エレベータを利用することができない。
【００１９】
また、前記の防犯運転回路２の動作に応じて常開接点２ａ２が閉路するとともに、このとき乗かごが１階床、すなわち基準階を離れていると乗かご基準階検出手段８の常閉接点８ｂが閉路していることから、電源Ｐ−常開接点２ａ２−常閉接点８ｂ−基準階復帰回路９−電源Ｎの回路が形成され、基準階復帰回路９が動作し乗かごを１階床へ走行させる。このとき防犯運転回路２が動作していることから乗場呼び運転回路７は無効となり乗かごは１階床へ直行する。そして、この１階床への走行に要する時間を計測し、要した時間を防犯運転継続タイマ３の所定時間に加算することによりあらかじめ定められた防犯運転の所定時間とすることができる。
【００２０】
乗かごが１階床に到着すると乗かご基準階検出手段８の常開接点８ａ１が閉路し、電源Ｐ−常開接点２ａ１−常開接点８ａ１−常閉接点６ｂ−防犯運転解除タイマ４−電源Ｎの回路が形成され、防犯運転解除タイマ４が計測を開始する。また、乗かご基準階検出手段８の常開接点８ａ２が閉路し、このとき制御手段１の常開接点１ａが閉路していることから、電源Ｐ−常開接点１ａ−常開接点８ａ２−戸開指令回路１１−電源Ｎの回路が形成され、戸開指令開路１１が動作する。
【００２１】
そして、前述した防犯運転解除タイマ４が所定時間を計測している間にかご呼び釦５１〜５５が操作されず、かご呼び検出手段６が動作しないと、その常閉接点６ｂは閉路したままとなり、防犯運転解除タイマ４の所定時間の計測とともにその常閉接点４ｂが開路し、防犯運転は解除される。一方、かごドアおよび乗場ドアの開扉に応じて利用者が乗かごに乗り込み、例えばかご呼び釦５５を操作すると、電源Ｐ−かご呼び釦５５−かご呼び運転回路５−電源Ｎの回路が形成され、乗かごは目的階である５階床へと移動し、到着とともに利用者は乗かごから降りる。なお、制御手段１の操作時、乗かごが基準階の１階床に着床している場合、乗かご基準階検出手段８の常開接点８ａ２は閉路していることから、制御手段１の操作に伴う常開接点１ａの閉路に応じて、かごドアおよび乗場ドアを開扉し、利用者は乗かごに乗り込む。
【００２２】
また、防犯運転の設定時、防犯運転回路２の動作に応じてその常閉接点２ｂ３が開路し、かご位置表示灯回路１３が消磁する。これにより乗場に設置されているかご位置表示灯のかご位置表示が非表示となり、乗場にいる他者はかご位置を確認することができない。このとき、かご位置表示を非表示とするとともに、「消灯中」という表示やかご位置とは関係ない文字や図柄を表示して、他者がかご位置を確認できないようにするとともに、故障と誤解することを防ぐ。また、このとき通常かご位置表示灯ととともに設置されている運転方向灯の表示を非表示とすることにより、他者が乗かごの運転方向を確認することも不可とする。
【００２３】
さらに、防犯運転回路２の動作に応じてその常閉接点２ｂ４が開路し、音声ガイダンス回路１４が消磁する。これにより音声による乗かご内外での乗かご到着等の案内が停止し、乗場にいる他者に乗かごの動きを知られることを防ぐ。また、防犯運転が終了しても乗かごが基準階に戻るまで、あるいは防犯運転が終了後も次の利用者が乗場釦７１ｕ〜７４ｕ、７２ｄ〜７５ｄまたは制御手段１を操作するまで、かご位置表示灯および運転方向灯の表示や音声ガイダンスを無効とすることもできる。
【００２４】
さらにまた、防犯運転回路２の動作に応じてその常閉接点２ａ４が閉路するとともに、乗かごが基準階に着床しており乗かご基準階検出手段８の常開接点８ａ３が閉路していることに応じ、電源Ｐ−常開接点２ａ４−常開接点８ａ３−戸閉タイミング回路１５−電源Ｎの回路が形成され、戸閉タイミング回路１５が動作する。これに応じてかごドアおよび乗場ドアの戸開時間および戸閉速度が通常時間および通常速度より短時間および高速に設定される。これにより制御手段１を操作した利用者が乗かごに乗り込んだ後、短時間のうちにかごドアおよび乗場ドアを閉扉することにより、他者が利用者を追って乗かごに乗り込むことを防ぐ。
【００２５】
また、防犯運転回路２の動作に応じてその常閉接点２ａ７が閉路するとともに、乗かごが基準階に着床しており乗かご基準階検出手段８の常開接点８ａ４が閉路していることに応じ、電源Ｐ−常開接点２ａ７−常開接点８ａ４−再戸開無効回路２０−電源Ｎの回路が形成され、再戸開無効開路２０が動作する。これに応じて制御手段１を操作した利用者が乗かごに乗り込んだ後、閉扉動作中にあるかごドアおよび乗場ドアを開扉しようとして他者が操作した乗場呼釦７１ｕの乗場呼びを無効とし、他者が乗かごに乗り込むことを防ぐ。
【００２６】
さらに、防犯運転回路２の動作に応じてその常閉接点２ａ５が閉路していることにより、乗かごが目的階に到着した際、利用者がこれらのかごドアおよび乗場ドアに設けられた窓ガラスを介して乗場に見知らぬ人がいることを認知し、目的階ではなく他の階床へ行くことを望み、乗かご内の第２の設定手段１６を操作すると、電源Ｐ−常開接点２ａ５−第２の設定手段１６−最寄階走行回路１７−電源Ｎの回路が形成され、最寄階走行回路１７が動作する。これに応じて、２階床ないしは４階床が登録された行先階であるときは１つ上の階床へ開扉せずに乗かごを走行させるとともに、最上階である５階床が登録された行先階であるときは、１つ下に位置する４階床に乗かごを走行させる。なお、乗かごが目的階に到着し、かごドアおよび乗場ドアが開扉動作にあるときに乗かご内の第２の設定手段１６を操作すると、最寄階走行回路１７の動作に応じて開扉中のかごドアおよび乗場ドアを閉じ、目的階とは異なる他の階床へと乗かごを走行させる。
【００２７】
さらにまた、防犯運転回路２の動作に応じてその常閉接点２ａ６が閉路していることにより、例えば制御手段１を操作した利用者が気をつけていたにもかかわらず他者が乗かごに乗り込んできたため、いち早く乗かごから降りることを望み、乗かご内の第３の設定手段１８を操作すると、電源Ｐ−常開接点２ａ６−第３の設定手段１８−最寄階停止回路１９−電源Ｎの回路が形成され、最寄階停止回路１９が動作する。これに応じて走行中にある乗かごは最寄階に停止し、かごドアおよび乗場ドアを開扉し、利用者は乗かご外へと非難する。
【００２８】
そして、設定手段１を操作した利用者の目的階である５階床に乗かごが到着し、利用者が乗かごから降りた後も防犯運転継続タイマ３は所定時間を計測し続け、かごドアおよび乗場ドアを閉じて乗かごを５階床で待機させる。この後、防犯運転継続タイマ３が所定時間を計測するとその常閉接点３ｂが開路し防犯運転が解除されるとともに、基準階復帰仕様である本実施形態のエレベータは、基準階である１階床に専用運転で、すなわち乗場呼びに応答することなく乗かごを直接１階床に復帰走行させる。なお、防犯運転を基準階である１階床に到着した後解除するようにしてもよい。
【００２９】
なお、本実施形態のエレベータは、制御手段１が１階床にのみ設置され、防犯運転が常に１階床からの上昇運転となることから、前述したように常開接点２ａ３、運転方向検出回路１２および常開接点１２ｕを設け、制御手段１の操作による防犯運転回路２の動作に応じてその常開接点２ａ３を閉路させ、電源Ｐ−常開接点２ａ３−運転方向検出回路１２−電源Ｎの回路を形成するとともに、運転方向検出回路１２を動作させてその常開接点１２ｕを閉路し、制御手段１の操作により基準階以外の階床に着床していた乗かごを基準階である１階床へと下降運転させるとき、また防犯運転継続タイマ３が所定時間を計測しているときに操作された下降乗場呼び釦７２ｄ〜７５ｄを有効とすることもできる。このように制御手段１を利用する利用者の目的階とは異なる方向の乗場呼びを有効とすることにより、利用者の安全性を考慮するとともに、エレベータの運転効率の低下を防ぐこともできる。また、本実施形態のエレベータは制御手段１が１階床にのみ設置され、防犯運転が常に１階床からの上昇運転となることから、下降乗場呼び釦７２ｄ〜７５ｄが対象となる運転方向検出回路１２の常開接点１２ｕが有効となるが、例えば制御手段１が２〜５階床の乗場にも設置されている場合、前述したように上昇乗場呼び釦７１ｕ〜７４ｕが対象となる運転方向検出回路１２の常開接点１２ｄを設けることにより、制御手段１を利用する利用者の目的階とは異なるそれぞれの方向の乗場呼びを有効とし、利用者の安全性を考慮するとともに、エレベータの運転効率の低下を防ぐこともできる。さらに、防犯運転の設定時に登録された、目的階への運転方向と逆方向となる乗場呼びを保留としておき、所定時間後に有効とすることもできる。このように防犯運転の設定時に登録された乗場呼びを単に無効とすることなく、所定時間後に乗場呼びに応答して乗かごを走行させることにより、制御手段１を利用する利用者の安全性を考慮するとともに、他のエレベータ利用者の便宜を図ることもできる。
【００３０】
また、本実施形態で述べた制御手段として、例えば利用者の持つカードを乗場に設置されたカードリーダで読み取りあらかじめ登録された利用者を認識させたり、利用者がブルートゥースなどの通信装置を持ち乗場に設置された受信機であらかじめ登録された利用者を認識させたり、携帯電話などによりエレベータにあらかじめ登録された利用者を認識させることにより、防犯運転を実施させることもできる。また、本実施形態では１階床の乗場に制御手段１を設けたものとしたが、例えば上昇乗場釦と下降乗場釦の同時押し、あるいは上昇乗場釦または下降乗場釦の長押しなどの通常と異なる操作方法により防犯運転を設定可能とすることもできる。さらに、前述した第２の制御手段１６および第３の制御手段１８は乗かご内に設置されている閉釦、開釦等でその機能を兼ねることもできる。
【００３１】
本実施形態によれば、利用者が設定手段１を操作することにより、利用者によるかご呼びの登録から乗かごの目的階への到着まで乗場呼びは無効となり、不審者が他の階床で乗場呼びを登録して乗かごを停止させ、乗かごに乗り込むことを防ぐことができる。また、防犯運転が設定されると乗かごが目的階に到着後も所定時間、継続して乗場呼びを無効とすることから、不審者が乗場呼びを登録し続けても目的階に着床した乗かごは乗場呼びにすぐに応答することがなく、したがって先の利用者を不審者がエレベータを利用して後から追いかけることを防ぐことができる。さらに、設定手段１の操作に応じて設定手段１が設置される１階床とは異なる階床に着床している乗かごを１階床に呼び寄せる間、乗場呼びを無効とすることにより、他の階床から乗かごに乗り込んだ不審者と１階床で鉢合わせとなる事態を回避することができる。さらにまた、かご呼びに応じて目的階に到着した後、乗かごを復帰階である１階床に復帰させる間、乗場呼びを無効とすることにより、不審者が先の利用者の目的階に隣接した階床から乗かごに乗り、エレベータを利用して先の利用者の目的階へと移動し後を追うことを防ぐことができる。
【００３２】
また、防犯運転が設定される所定時間は、設定手段１が操作された１階床から目的階の運転方向にある端階、すなわち５階床までの乗かごの往復走行に要する時間以上に設定されることから、乗かごの次の呼びに対する応答を、目的階へ到着した乗かごから降りた利用者が自宅まで到達することのできる時間を考慮したものとし、利用者の安全性を図ることができる。さらに、設定手段１の操作後、所定時間経過してもかご呼びが登録されないとき通常運転に切替えることから、不必要に防犯運転が継続され、エレベータの効率の低下を招くことを防ぐことができる。さらにまた、乗場呼びを無効としているとき、乗場に設置されるかご位置表示灯のかご位置表示、およびエレベータ運転方向灯の運転方向表示を非表示とすることにより、他者が乗かごの位置および運転方向を確認することも不可とし、より安全性を増すことができる。また、かご位置表示、および運転方向表示を非表示とするとき、「消灯中」という表示やかご位置とは関係ない文字や図柄を表示することにより、他者がエレベータの故障と誤解することを防ぐことができる。
【００３３】
さらに、あらかじめ定められた時間帯に設定手段１により防犯運転を設定可能とすることにより、例えば比較的安全な昼間の時間帯は通常運転によりエレベータを運行することにより、エレベータの運転効率の保持、およびエレベータの安全性の確保の両立を図ることができる。さらにまた、乗場呼びを無効としているとき、音声ガイダンス手段による音声案内を停止することにより、乗場にいる他者に乗かごの動きを知られることを防ぎ、安全性の向上を図ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security operation method for an elevator, and more particularly to a security operation method for an elevator that prevents crime using a car by setting the security operation.
[0002]
[Prior art]
There are so-called dedicated operation and car-call priority operation as types of operation that give priority to elevator car call. Dedicated operation allows key persons, such as company executives, to smoothly move between floors.By operating the exclusive operation changeover switch, the car is directly driven to the destination floor registered by car call without responding to the hall call. Things. Car call priority operation always performs car call priority operation to prevent passengers from meeting each other at accommodation facilities, etc., and does not respond even if a hall call is registered while the car is running. The vehicle is driven directly to the destination floor registered by the call, and responds to the hall call registered earlier according to the degaussing of the registration of the car call.
[0003]
Conventionally, such a dedicated operation and a car call priority operation are applied as a security operation device. In other words, when a woman living in an apartment house or other apartment goes out at night and uses the elevator to the floor where her home is located, she is usually connected to the outside through an entrance so that she does not ride in a car with a stranger. They look around the landing on the first floor and make sure no one is there before using the elevator. Even if you check the safety of the first floor and get into the car, you can move between the first floor and the stairs in normal operation, for example, there was a possibility that a suspicious person could get into the car from the second floor. By performing the dedicated operation or the car call priority operation as described above, it is possible to prevent the suspicious person from stopping the car by using the hall call on the other floor and coming in.
[0004]
2. Description of the Related Art Conventionally, as this kind of security driving device, there is a security driving device in which a card reader is installed at a landing and a dedicated operation is performed by causing the card reader to read a card. (For example, refer to Patent Document 1).
[0005]
In addition, it detects that an intruder has invaded any floor except the entrance floor of the building and notifies the surveillance center and invalidates the hall calls on multiple floors and the car calls in the car to enter. A security guard who prevented the intruder from using the elevator and rushed to the car that ran directly to the entrance floor, operated the dedicated operation switch to enable the hall call and car call, and quickly entered the floor where the intruder entered. There are elevator operating devices that make it accessible. (For example, see Patent Document 2).

(Paragraph Nos. 0016-0019, FIG. 1)
[0008]
[Problems to be solved by the invention]
By the way, in the former disclosed in Japanese Patent Application Laid-Open No. 2-204283, a dedicated operation is performed up to the destination floor by inserting a card into a card reader, and after arrival, the exclusive operation is canceled and the hall call becomes effective. However, the floor used by the previous user, ie, the destination floor, can be relatively easily determined by the travel time of the car. For this reason, for example, after the cardholder departs to the destination floor by dedicated driving at night when the number of users is small, the suspicious person calculates the cardholder's destination floor from the traveling time of the car and continues to register the hall call at the landing, It was possible to get into the car that responded to the hall call after the exclusive operation and move to the target destination floor. In addition, in this security driving device, in order to prevent the destination floor of the previous user from being determined by the car position of the car position indicator light, the car position is not changed until the hall call becomes valid according to the dedicated driving. Although it is displayed, while preventing the previous user from determining the destination floor, there is a possibility that other users may mistake the elevator for a malfunction.
[0009]
Further, the latter one disclosed in Japanese Patent Application Laid-Open No. Hei 7-53153 allows a security guard or the like to quickly reach the floor where the intruder has entered, but prevents the use of the elevator after the intruder has entered. As a security driving device, it is impossible to prevent a suspicious individual from knowing the destination floor of the previous user, and after using this user, getting into the elevator and moving to the target destination floor.
[0010]
The present invention has been made in view of such a situation in the prior art, and has as its object the security operation of an elevator that can prevent a suspicious person from moving to the destination floor of a previous user using an elevator. It is to provide a device.
[0011]
[Means for Solving the Problems]
In order to achieve this object, the present invention registers a hall call by operating a hall button installed in the hall and calls the car, and registers a car call by operating a car call button installed in the car. In an elevator for driving a car to a destination floor, in an elevator security driving method for preventing crime using the car by setting security driving, a setting provided in at least one of a landing and a car. A first step of invalidating the hall call from the registration of the car call to the arrival of the car at the destination floor in accordance with the operation of the means; Even after the vehicle arrives at the floor, security operation including a second step of continuously invalidating the hall call is set.
[0012]
According to the present invention, when the user operates the setting means, the hall call is invalidated from the registration of the car call to the arrival of the car at the destination floor. This prevents a suspicious individual from registering a hall call on another floor, stopping the car, and getting into the car. Further, after the car arrives at the destination floor, the hall call is invalidated continuously for a predetermined time. As a result, even if the suspicious person keeps registering the hall call, the car that has landed on the destination floor does not immediately respond to the hall call, so the suspicious person chases the previous user later by using the elevator Can be prevented.
[0013]

It is, of course, provided. Furthermore, the description of the descent hall call button 73d installed on the floor of the third floor and the descent hall call button 74d installed on the hall of the fourth floor are omitted for convenience, but the above-mentioned ones are provided for each hall. It is, of course, provided.
[0017]
In this embodiment, at normal time, when the user operates one of the hall call buttons 71u to 75d to register a hall call, the hall call driving circuit 7 operates to move the car to the floor. Then, the user gets into the car and operates any of the car call buttons 51 to 55 to register the car call, and the car call driving circuit 5 operates accordingly, and the car travels to the destination floor. Let it.
[0018]
In the present embodiment, for example, in a predetermined time period from 20:00 to 6:00, the security operation setting clock 10 operates, and the normally open contact 10a is closed. When the user operates the setting means 1 during this time zone, a circuit of the power supply P-setting means 1-normally open contact 10a-security operation circuit 2-power supply N is formed, the security operation circuit 2 operates, and the normally closed contact is operated. 2b1 and 2b2 are opened and the hall call operation circuit 7 becomes invalid, and only the car call operation circuit 5 becomes effective. At this time, when the normally open contact 2a1 is closed, a circuit of the power supply P, the normally open contact 2a1, the normally closed contact 3b, the normally closed contact 4b, the security operation circuit 2, and the power supply N is formed. A circuit of power supply P-normally open contact 2a1-security operation continuation timer 3-power supply N is formed, and the security operation continuation timer 3 starts measurement. When the security operation is set, the hall call is invalidated from the start to the cancellation, and the elevator cannot be used by another user's hall call. The time limit of the security operation continuation timer 3 is set to be equal to or longer than the time required for the car to reciprocate from the first floor where the setting means 1 is installed to the fifth floor, which is the top floor, and other users are During that time, the elevator cannot be used.
[0019]
The normally open contact 2a2 is closed according to the operation of the security operation circuit 2, and at this time, if the car is off the first floor, that is, the reference floor, the normally closed contact of the car standard floor detecting means 8 Since the circuit 8b is closed, a circuit of the power supply P-normally open contact 2a2-normally closed contact 8b-reference floor return circuit 9-power supply N is formed, and the reference floor return circuit 9 operates to move the car to the first floor. To run. At this time, since the security operation circuit 2 is operating, the hall call operation circuit 7 is invalidated and the car goes straight to the first floor. Then, the time required for traveling to the first floor is measured, and the required time is added to the predetermined time of the security operation continuation timer 3 so that the predetermined time for the security operation can be set in advance.
[0020]
When the car arrives at the first floor, the normally open contact 8a1 of the car reference floor detecting means 8 is closed, and the power supply P-normally open contact 2a1-normally open contact 8a1-normally closed contact 6b-security operation release timer 4-power supply An N circuit is formed, and the security operation release timer 4 starts measuring. Also, since the normally open contact 8a2 of the car reference floor detecting means 8 is closed and the normally open contact 1a of the control means 1 is closed at this time, the power supply P-normally open contact 1a-normally open contact 8a2-door The open command circuit 11-the circuit of the power supply N are formed, and the door open command open circuit 11 operates.
[0021]
If the car call buttons 51 to 55 are not operated and the car call detection means 6 is not operated while the above-mentioned crime prevention operation cancel timer 4 is measuring a predetermined time, the normally closed contact 6b remains closed. At the same time, the normally closed contact 4b is opened along with the measurement of the predetermined time by the security operation release timer 4, and the security operation is released. On the other hand, when the user gets into the car in response to the opening of the car door and the landing door, and operates the car call button 55, for example, a circuit of the power supply P-car call button 55-car call operation circuit 5-power supply N is formed. Then, the car moves to the fifth floor, which is the destination floor, and upon arrival, the user gets off the car. When the control means 1 is operated, if the car is on the first floor of the reference floor, the normally open contact 8a2 of the car reference floor detecting means 8 is closed. The car door and the landing door are opened in accordance with the closing of the normally open contact 1a accompanying the operation, and the user gets into the car.
[0022]
When the security operation is set, the normally closed contact 2b3 is opened according to the operation of the security operation circuit 2, and the car position indicating lamp circuit 13 is demagnetized. As a result, the car position display of the car position indicator light installed in the hall is hidden, and other people at the hall cannot confirm the car position. At this time, the display of the car position is hidden, and the display "OFF" and characters and designs that are not related to the car position are displayed to prevent others from checking the car position, To prevent Also, at this time, by hiding the display of the driving direction light installed together with the normal car position indicating light, it is also impossible for another person to check the driving direction of the car.
[0023]
Further, the normally closed contact 2b4 opens according to the operation of the security operation circuit 2, and the voice guidance circuit 14 is demagnetized. As a result, the guidance of the arrival of the car inside and outside the car by voice is stopped, and the movement of the car is prevented from being known to others at the hall. Further, the car position is maintained until the car returns to the reference floor even after the security operation is completed, or until the next user operates the hall buttons 71u to 74u, 72d to 75d or the control means 1 after the security operation is completed. The display of the indicator light and the driving direction light and the voice guidance can be invalidated.
[0024]
Furthermore, the normally closed contact 2a4 is closed according to the operation of the security operation circuit 2, and the car is landing on the reference floor, and the normally open contact 8a3 of the car reference floor detecting means 8 is closed. Accordingly, a circuit of power supply P-normally open contact 2a4-normally open contact 8a3-door closing timing circuit 15-power supply N is formed, and door closing timing circuit 15 operates. Accordingly, the door opening time and the door closing speed of the car door and the landing door are set to the normal time and a shorter time and a higher speed than the normal speed. As a result, after the user operating the control means 1 gets into the car, the car door and the landing door are closed within a short time, thereby preventing another person from getting into the car following the user.
[0025]
In addition, the normally closed contact 2a7 is closed according to the operation of the security operation circuit 2, the car is landing on the reference floor, and the normally open contact 8a4 of the car reference floor detecting means 8 is closed. Accordingly, a circuit of power supply P-normally opened contact 2a7-normally opened contact 8a4-reopening invalid circuit 20-power supply N is formed, and reopening invalid opening circuit 20 operates. In response to this, after the user who operated the control means 1 gets into the car, the car call and the hall call button 71u operated by others to open the car door and the hall door during the door closing operation are invalidated. Prevent others from getting into the car.
[0026]
Further, since the normally closed contact 2a5 is closed in response to the operation of the security operation circuit 2, when the car arrives at the destination floor, the user can use the window glass provided on the car door and the landing door. , It is recognized that there is an unknown person at the landing, and it is desired to go to another floor instead of the destination floor. When the second setting means 16 in the car is operated, the power supply P-normally open contact 2a5- A circuit of the second setting means 16-the nearest floor traveling circuit 17-the power supply N is formed, and the nearest floor traveling circuit 17 operates. Accordingly, when the second floor or the fourth floor is the registered destination floor, the car is driven to the next higher floor without opening the door, and the fifth floor, which is the top floor, is registered. If the destination floor has been set, the car is driven to the fourth floor located one level below. In addition, when the car arrives at the destination floor and the second setting means 16 in the car is operated when the car door and the landing door are in the door opening operation, the car is opened according to the operation of the nearest floor traveling circuit 17. Close the car door inside the door and the landing door, and drive the car to another floor different from the destination floor.
[0027]
Furthermore, since the normally closed contact 2a6 is closed in accordance with the operation of the security operation circuit 2, for example, even if the user who operates the control means 1 is careful, another person may be in the car. Since the passenger has got on the vehicle, he / she wants to get out of the car promptly, and operates the third setting means 18 in the car, the power supply P-normally open contact 2a6-the third setting means 18-the nearest floor stop circuit 19-the power supply N circuits are formed, and the nearest floor stop circuit 19 operates. In response to this, the car that is running stops at the nearest floor, the car door and the landing door are opened, and the user is blamed outside the car.
[0028]
After the car arrives at the fifth floor, which is the destination floor of the user who operated the setting means 1, the security operation continuation timer 3 continues to measure a predetermined time even after the user gets off the car, And the landing door is closed and the car waits on the fifth floor. Thereafter, when the crime prevention operation continuation timer 3 measures a predetermined time, the normally closed contact 3b is opened to release the crime prevention operation, and the elevator according to the present embodiment, which has the reference floor return specification, has the first floor as the reference floor. Then, the car is returned to the first floor directly by exclusive operation, that is, without responding to the hall call. The security operation may be canceled after arriving at the first floor, which is the reference floor.
[0029]
In the elevator of the present embodiment, the control means 1 is installed only on the first floor, and the crime prevention operation is always an ascending operation from the first floor. 12 and a normally open contact 12u, the normally open contact 2a3 is closed in response to the operation of the security operation circuit 2 by the operation of the control means 1, and the power supply P-normally open contact 2a3-driving direction detection circuit 12-power supply N A circuit is formed, the driving direction detection circuit 12 is operated to close the normally open contact 12u, and the car that has landed on a floor other than the reference floor by operating the control means 1 is the reference floor 1 The descent hall call buttons 72d to 75d operated when the descent operation to the floor is performed or when the security operation continuation timer 3 is measuring a predetermined time can be made effective. In this way, by making the hall call in a direction different from the destination floor of the user using the control means 1 effective, it is possible to consider the safety of the user and to prevent a decrease in the operating efficiency of the elevator. In the elevator of the present embodiment, the control means 1 is installed only on the first floor, and the crime prevention operation is always an ascending operation from the first floor. Although the normally open contact 12u of the circuit 12 is effective, for example, when the control means 1 is also installed on the landings on the second to fifth floors, the driving directions in which the ascending hall call buttons 71u to 74u are targeted as described above. By providing the normally open contact 12d of the detection circuit 12, it is possible to enable landing calls in respective directions different from the destination floor of the user using the control means 1 and to consider the safety of the user and to operate the elevator. A decrease in efficiency can be prevented. Further, it is also possible to suspend a hall call registered in the setting of the security operation, which is in the opposite direction to the driving direction to the destination floor, and to make it valid after a predetermined time. As described above, the safety of the user using the control means 1 can be improved by running the car in response to the hall call after a predetermined time without simply invalidating the hall call registered at the time of the setting of the security operation. This can be taken into account as well as the convenience of other elevator users.
[0030]
Further, as the control means described in the present embodiment, for example, a card held by a user is read by a card reader installed at the hall to recognize a registered user in advance, or the user has a communication device such as Bluetooth and has a hall. The security operation can be performed by recognizing a user registered in advance by a receiver installed in the vehicle or by recognizing a user registered in the elevator by a mobile phone or the like. In the present embodiment, the control means 1 is provided at the landing on the first floor. However, for example, simultaneous pressing of the ascending hall button and the descending hall button, or long press of the ascending hall button or the descending hall button may be performed. Security operation can be set by different operation methods. Further, the above-mentioned second control means 16 and third control means 18 can also have the function of a close button, an open button, and the like provided in the car.
[0031]
According to the present embodiment, when the user operates the setting means 1, the hall call is invalidated from the registration of the car call to the arrival of the car at the destination floor by the user, and the suspicious person is moved to another floor. It is possible to register the hall call and stop the car, thereby preventing the car from getting into the car. In addition, when security operation is set, the car will continue to invalidate the hall call for a predetermined time after arriving at the destination floor, so even if the suspicious person keeps registering the hall call, he will land on the destination floor.

Furthermore, in response to the operation of the second setting means 16 installed in the car at the time of arrival at the destination floor, the opening of the car door and the landing door is invalidated, and the door is opened to another floor different from the destination floor. By driving the car, when the car arrives at the destination floor, when the user recognizes that there is a stranger at the hall, the second setting means 16 is operated to move to another floor. Can be avoided. Further, in response to the operation of the third setting means 18 installed in the car, the car is stopped at the nearest floor, and the car door and the landing door are opened to operate the control means 1. When another person gets into the car despite the care of the person, the third setting means 18 can be operated to quickly slam the car.
