Description

本発明は、地震や火災等の災害発生時にエレベータおける人的災害を最小限に抑制するエレベータの災害時運転制御装置に関する。   The present invention relates to an elevator operation control apparatus for an elevator that minimizes a human disaster in an elevator when a disaster such as an earthquake or a fire occurs.

近年、地震等の災害発生時にエレベータのかご内に利用客が閉じ込められる人的災害を防ぐとともに、エレベータ機材の損傷を最小限に抑制する目的で、エレベータに地震感知器を備えている。そして、地震発生時に、その地震感知器で感知された地震の強度(加速度レベル)に応じたエレベータ運転制御方法を採用している。   In recent years, in order to prevent human disasters in which passengers are trapped in an elevator car when a disaster such as an earthquake occurs, an elevator is provided with an earthquake detector in order to minimize damage to elevator equipment. Then, when an earthquake occurs, an elevator operation control method is employed according to the intensity (acceleration level) of the earthquake detected by the earthquake detector.

例えば、強度が150ガル以上の「高」レベルの場合、エレベータのかごをその位置で即時停止させ、揺れが収まってから保守員の安全確認後、保守員や管理者のマニュアル操作で最寄階へ移動させる。   For example, if the strength is at a “high” level of 150 gal or more, stop the elevator car immediately at that position, check the safety of the maintenance personnel after the shaking has stopped, and then manually operate the maintenance personnel and the manager Move to.

強度が80〜150ガルの「低」レベルの場合、エレベータのかごを停止せずに最寄階に移動させて当該最寄階でかごの戸開を実施して、かご内の利用客を当該最寄階のエレベータホールへ避難させる。そして、かごのドアを閉じて、エレベータの運転を停止して、エレベータ保守管理会社の保守員の点検、再起動待ちとなる。   When the strength is 80 to 150 gals, the level is low and the elevator car is moved to the nearest floor without stopping, and the car is opened on the nearest floor. Evacuate to the nearest elevator hall. Then, the car door is closed, the operation of the elevator is stopped, and maintenance and maintenance of the elevator maintenance management company are awaited.

強度が例えば、40〜80ガルの「極低」レベルの場合、エレベータのかごを停止せずに最寄階に移動させ、所定時間後に運転を再開する。このように、地震の強度に応じた地震管制運転を実施している。   In the case of the “very low” level of 40 to 80 gal, for example, the elevator car is moved to the nearest floor without stopping, and the operation is resumed after a predetermined time. In this way, seismic control operation is implemented according to the intensity of the earthquake.

また、建屋の各階には建築基準法に基づいて火災感知器が取付けられている。エレベータは、その火災感知器の火災感知を取込み、エレベータのかご運転時に、火災が発生すると、かごを1階等のこの建屋の出入り口(玄関)に通じる予め定められた避難階へ移動させて、当該避難階で戸開し、かご内の利用客を当該避難階のエレベータホールへ避難させる火災管制運転を実行している。   In addition, fire detectors are installed on each floor of the building based on the Building Standard Law. The elevator takes in the fire detection of the fire detector, and when a fire occurs during the elevator car operation, move the car to a predetermined evacuation floor that leads to the entrance (entrance) of this building such as the first floor, Fire control operation is performed to open the door on the evacuation floor and evacuate passengers in the car to the elevator hall on the evacuation floor.

さらに、特許文献1には、火災発生時に、エレベータのかごの退避階を、火災発生階から所定階数下がった階以下の階から選択している。一般に、火災発生時には、火災発生階より上側の階は延焼の可能性が高く、かつ有毒ガスを含む煙が充満する可能性が高いので、火災発生時におけるかごの移動範囲を制限している。
特開2005−82293号公報
Furthermore, in Patent Document 1, when a fire breaks out, the elevator car retreat floor is selected from floors below a predetermined number of floors lower than the fire occurrence floor. In general, when a fire breaks out, the floor above the fire-breaking floor has a high possibility of spreading fire and is highly likely to be filled with smoke containing toxic gas, so the range of movement of the car at the time of the fire is limited.
JP 2005-82293 A

しかしながら、上述したように、地震発生時の対策と火災発生時の対策とをそれぞれ個別に実施するエレベータの災害時の運転制御手法においても、まだ解消すべき次のような課題があった。   However, as described above, even in the operation control method at the time of disaster of an elevator that individually implements the countermeasures at the time of earthquake occurrence and the countermeasures at the time of fire occurrence, there are the following problems to be solved.

すなわち、前述したように、地震感知器が「低」又は「極低」の地震を感知すると、通常運転が停止して地震管制運転が開始される。この地震管制運転期間中、エレベータの移動中のかごは最寄階に停止を試みる。しかし、地震発生時は火災も同時に発生する可能性が高く、最寄階が火災階(火災の災害を受けている階)であることも考えられる。この場合、火災階でかご内の利用客を降ろすことになり、かえって利用客を危険にさらすことになる。   That is, as described above, when the earthquake detector detects a “low” or “very low” earthquake, the normal operation is stopped and the earthquake control operation is started. During this seismic control period, the elevator moving car tries to stop at the nearest floor. However, when an earthquake occurs, there is a high possibility that a fire will occur at the same time, and it is possible that the nearest floor is the fire floor (the floor receiving the fire disaster). In this case, the passengers in the car are lowered on the fire floor, and the users are put in danger.

また、火災感知器が火災を感知すると、通常運転が停止して地震管制運転が開始される。この火災管制運転期間中、かごは避難階に直行する。この火災管制運転期間中に「低」又は「極低」の地震が発生したとする。この場合、火災管制運転より地震管制運転が優先されている場合が多く、エレベータのかごは最寄階停止を試みる。したがって、前述と同様の問題が生じる。   When the fire detector detects a fire, normal operation stops and seismic control operation starts. During this fire control operation period, the car goes straight to the evacuation floor. Assume that a “low” or “very low” earthquake occurred during this fire control period. In this case, earthquake control operation is often prioritized over fire control operation, and elevator cars try to stop the nearest floor. Therefore, the same problem as described above occurs.

エレベータのかごを動かすことが困難なほどの揺れの場合は、最寄階停止が好ましいが、通常運転するのには問題ないほどの揺れでは火災からの避難を優先させることが望ましい場合もある。   In the case of shaking that makes it difficult to move the elevator car, it is preferable to stop at the nearest floor. However, it may be desirable to give priority to evacuation from a fire if the shaking is not problematic for normal operation.

また、建屋に組込まれたエレベータにおいては、昇降路の上側の機械室に設置された巻上機に、一端にかごが取付けられ、他端に吊り合い錘が取付けられた主ロープが掛けられている。そして、巻上機を回転駆動することにより、かごが昇降路内を上下移動する。かごの上下移動に連動して、吊り合い錘も上下移動する。この吊り合い錘が昇降路内を円滑に上下移動するために、この吊り合い錘をレールに沿って上下移動させている。   In an elevator built in a building, a hoist installed in a machine room above the hoistway is hung by a main rope with a car attached to one end and a suspension weight attached to the other end. Yes. Then, the car moves up and down in the hoistway by rotating the hoisting machine. The suspension weight moves up and down in conjunction with the vertical movement of the car. In order for the suspension weight to move up and down smoothly in the hoistway, the suspension weight is moved up and down along the rail.

したがって、地震時には、地震の揺れの影響で吊り合い錘がレールから外れたり、レール自体が曲がってしまったりする場合も考えられる。このような場合、通常、エレベータは停止してしまう。しかし、火災が同時に発生している場合は単純に停止するだけでは、かご内の利用客は火災から逃げ遅れることが懸念される。   Therefore, during an earthquake, the suspended weight may be detached from the rail or the rail itself may be bent due to the influence of the shaking of the earthquake. In such a case, the elevator usually stops. However, if fires are occurring at the same time, it is feared that passengers in the car will be late to escape from the fire by simply stopping.

本発明はこのような事情に鑑みてなされたものであり、たとえ地震と火災とが同じ時間帯に生じたとしても、地震と火災の発生状況に応じて、エレベータの利用客にとって十分に安全性が確保できる管制運転を実現できるエレベータの災害時運転制御装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and even if an earthquake and a fire occur in the same time zone, it is sufficiently safe for elevator users depending on the occurrence of the earthquake and the fire. It is an object of the present invention to provide an elevator operation control device that can realize a control operation capable of ensuring safety.

本発明は、地震感知器の地震感知により運転中のエレベータのかごを最寄階へ移動させて戸開する地震管制運転を実行するとともに、火災感知器の火災感知により運転中のかごを予め定められた避難階へ移動させて戸開する火災管制運転を実行するエレベータの災害時運転制御装置に適用される。   The present invention executes a seismic control operation in which an elevator car in operation is moved to the nearest floor by the earthquake detection of the earthquake detector and opens, and a car in operation is determined in advance by the fire detection of the fire detector. It is applied to a disaster operation control device for an elevator that performs fire control operation that moves to a designated evacuation floor and opens the door.

そして、上記課題を解決するために本発明のエレベータの災害時運転制御装置おいては、地震管制運転と火災管制運転とのいずれか一方の管制運転の実行中に、他方の管制運転に対応する地震又は火災を感知すると、実行中の管制運転におけるかご位置と移動方向と前記新たに生じた地震又は火災の情報とに基づいて、かごを最適階へ移動させて戸開する複合管制運転を実行する複合管制運転手段を備えている。   And in order to solve the said subject, in the operation control apparatus at the time of disaster of the elevator of this invention, it corresponds to the other control operation during execution of either one of seismic control operation and fire control operation. When an earthquake or fire is detected, based on the position and direction of the car in the current control operation and the information on the newly generated earthquake or fire, the car is moved to the optimal floor and the combined control operation is performed. A composite control operation means is provided.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、火災感知器は火災位置を検出し、地震感知器は地震強度を検出し、複合管制運転手段は、かごを移動させて戸開する最適階を、実行中の管制運転におけるかご位置と移動方向と、検出された火災位置の階及び地震強度に基づいて選択する最適階選択手段を有する。   In another aspect of the elevator operation control apparatus according to the invention described above, the fire detector detects the fire position, the earthquake detector detects the seismic intensity, and the combined control operation means moves the car. Optimal floor selection means is provided for selecting the optimal floor to be opened based on the car position and moving direction in the control operation being performed, the floor of the detected fire position, and the earthquake intensity.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、最適階選択手段は、火災管制運転中に地震を感知した場合、火災管制運転によるかご移動方向が避難階方向で、かつ現在のかご位置と避難階との間に火災位置が存在し、地震強度が低レベルのとき、現在のかご位置と火災位置との間の階を最適階と選択する。   Further, in another aspect of the elevator operation control device for an elevator according to the invention described above, the optimum floor selecting means detects the earthquake during the fire control operation, and the car movement direction by the fire control operation is the evacuation floor direction. In addition, when a fire position exists between the current car position and the evacuation floor and the earthquake intensity is low, the floor between the current car position and the fire position is selected as the optimum floor.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、最適階選択手段は、地震管制運転中に火災を感知した場合、地震管制運転によるかごの移動方向が反避難階方向で、かつ現在のかご位置と火災位置との間に最寄階が存在し、地震強度が低レベルのとき、かごを最寄階で移動方向を反転し、かつかごが火災位置を過ぎた階を最適階と選択する。   Further, in another aspect of the elevator operation control device according to the invention described above, the optimum floor selection means is configured such that when a fire is detected during the earthquake control operation, the moving direction of the car by the earthquake control operation is the anti-evacuation floor direction. When the nearest floor exists between the current car position and the fire position, and the earthquake intensity is low, the direction of movement of the car is reversed at the nearest floor and the car passes the fire position. Is selected as the optimal floor.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、最適階選択手段は、地震管制運転中に火災を感知した場合、地震管制運転によるかごの移動方向が反避難階方向で、かつ地震強度が極低レベルのとき、火災位置の如何に係わらず、かごを最寄階で移動方向を反転し、かつ避難階を最適階と選択する。   Further, in another aspect of the elevator operation control device according to the invention described above, the optimum floor selection means is configured such that when a fire is detected during the earthquake control operation, the moving direction of the car by the earthquake control operation is the anti-evacuation floor direction. When the seismic intensity is extremely low, the moving direction is reversed at the nearest floor regardless of the fire position, and the evacuation floor is selected as the optimum floor.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、かごの吊り合い錘が、かごの上下移動に連動して上下移動するためのレールから外れたことを検出するレール外れ検出部を備えている。さらに、複合管制運転手段は、吊り合い錘のレール外れ検出の場合、エレベータのかごを移動させて戸開する最適階を、実行中の管制運転におけるかごの位置と、このかご位置と移動方向と地震又は火災の情報と、かご位置と吊り合い錘との位置関係とに基づいて選択する。   According to another invention, in the elevator operation control device of the above-described invention, the off-rail detecting that the suspended weight of the car is detached from the rail for moving up and down in conjunction with the up-and-down movement of the car.

Select based on earthquake or fire information and the positional relationship between the car position and the suspension weight.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、かごの吊り合い錘が、かごの上下移動に連動して上下移動するためのレールが曲がったこと及び曲がり位置を検出するレール曲がり検出部を備えている。そして、複合管制運転手段は、レール曲がり検出の場合、エレベータのかごを移動させて戸開する最適階を、実行中の管制運転におけるかご位置と、このかご位置と移動方向と地震又は火災の情報と、かご位置とレール曲がり位置との位置関係とに基づいて選択する。   According to another invention, in the elevator operation control apparatus of the invention described above, the suspension weight of the car detects that the rail for moving up and down in conjunction with the vertical movement of the car is bent and the bent position is detected. The rail bending detection unit is provided. The combined control operation means, in the case of rail bending detection, determines the optimal floor where the elevator car is moved and opened, the car position in the current control operation, the car position, the moving direction, and information on earthquake or fire. And the positional relationship between the car position and the rail bending position.

また、別の発明は、上述した発明のエレベータの災害時運転制御装置において、かごの吊り合い錘が、かごの上下移動に連動して上下移動するためのレールが曲がったこと及び曲がり位置を検出するレール曲がり検出部を備えている。そして、複合管制運転手段は、地震管制運転中に火災を感知した場合でかつレール曲がり検出の場合、地震管制運転によるかご移動方向が反避難階方向で、かつ地震強度が極低レベルのとき、火災位置の如何に係わらず、かごを最寄階で移動方向を反転し、かつ避難階を最適階と選択する。   According to another invention, in the elevator operation control apparatus of the invention described above, the suspension weight of the car detects that the rail for moving up and down in conjunction with the vertical movement of the car is bent and the bent position is detected. The rail bending detection unit is provided. And, when the fire control is detected during the earthquake control operation and the rail bend is detected, the complex control operation means is the case where the car movement direction by the earthquake control operation is the anti-evacuation floor direction and the earthquake intensity is extremely low level. Regardless of the location of the fire, reverse the direction of movement of the car at the nearest floor and select the evacuation floor as the optimal floor.

このような構成のエレベータの災害時運転制御装置においては、地震管制運転又は火災管制運転の実行中に他方の火災又は地震を感知すると、新たに両者の条件を組入れた複合管制運転を実行するので、たとえ地震と火災とが同じ時間帯に生じたとしても、地震と火災の発生状況に応じた運転となり、エレベータの利用客にとって十分に安全性が確保できる。   In an emergency operation control system for an elevator having such a configuration, when the other fire or earthquake is detected during the execution of the earthquake control operation or fire control operation, the composite control operation newly incorporating both conditions is executed. Even if an earthquake and a fire occur in the same time zone, the operation is made according to the situation of the occurrence of the earthquake and the fire, and sufficient safety can be ensured for elevator users.

以下、本発明の各実施形態を図面を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(第1実施形態)
図1(a)は、本発明の第1実施形態に係わるエレベータの災害時運転制御装置が組込まれたエレベータの全体構成を示す模式図である。
(First embodiment)
FIG. 1A is a schematic diagram showing an overall configuration of an elevator in which an elevator disaster operation control apparatus according to a first embodiment of the present invention is incorporated.

建屋内に設けられた昇降路1の上側に巻上機2、災害時運転制御装置3が設けられている。巻上機2には、一端にかご4が取付けられ、他端に吊り合い錘5が取付けられた主ロープ6が掛けられている。そして、巻上機2を回転駆動することにより、かご4が昇降路1内を上下移動する。かご4の上下移動に連動して、吊り合い錘5も上下移動する。この吊り合い錘5が昇降路1内を円滑に上下移動するために、昇降路1の側壁に上下方向に、図1(b)に示すように、「コ」字型断面形状を有する一対のレール7a、7bが取付けられており、吊り合い錘5は、このレール7a、7bに導かれて、昇降路1内を上下移動する。   A hoisting machine 2 and a disaster operation control device 3 are provided above the hoistway 1 provided in the building. The hoisting machine 2 has a main rope 6 with a car 4 attached to one end and a suspension weight 5 attached to the other end. And the car 4 moves up and down in the hoistway 1 by rotationally driving the hoisting machine 2. In conjunction with the vertical movement of the car 4, the suspension weight 5 also moves up and down. In order for the suspension weight 5 to move up and down smoothly in the hoistway 1, a pair of “U” -shaped cross-sections are formed on the side walls of the hoistway 1 in the vertical direction as shown in FIG. Rails 7a and 7b are attached, and the suspended weight 5 is guided by the rails 7a and 7b and moves up and down in the hoistway 1.

この昇降路1の1階の下方のピット内には、地震感知器8が据え付けられている。地震感知器8は地震の揺れの強度(加速度レベル)を感知し、強度が150ガル以上の強レベルの場合、「強」の感知信号を建屋の管理人が常駐する監視室9を介して、災害時運転制御装置3へ送信する。同様に、強度が80〜150ガルの「低」レベルの場合、「低」の感知信号を送出し、40〜80ガルの「極低」レベルの場合、「極低」の感知信号を送出する。   An earthquake detector 8 is installed in a pit below the first floor of the hoistway 1. The earthquake detector 8 senses the intensity (acceleration level) of the shaking of the earthquake, and when the intensity is a strong level of 150 gal or more, a “strong” detection signal is sent through the monitoring room 9 where the building manager is stationed. It transmits to the operation control apparatus 3 at the time of a disaster. Similarly, when the intensity is at a “low” level of 80 to 150 gal, a “low” sensing signal is transmitted, and when the intensity is at an “ultra low” level of 40 to 80 gal, a “very low” sensing signal is transmitted. .

さらに、建屋の各階の天井には火災感知器10が取付られており、該当階の火災を感知すると、火災感知信号を監視室9を経由して災害時運転制御装置3へ送信する。かご4内にはかご呼び登録装置11が取付けられ、各階のエレベータホールには乗場呼び登録装置12が取付けられている。各呼び登録装置11、12の呼び信号は災害時運転制御装置3へ送信される。   Furthermore, a fire detector 10 is attached to the ceiling of each floor of the building. When a fire on the corresponding floor is detected, a fire detection signal is transmitted to the disaster operation control device 3 via the monitoring room 9. A car call registration device 11 is installed in the car 4, and a hall call registration device 12 is installed in the elevator hall on each floor. The call signals of the call registration devices 11 and 12 are transmitted to the disaster operation control device 3.

図2は、機械室内に設けられた例えばコンピュータ等の情報処理装置からなる災害時運転制御装置3の概略構成を示すブロック図である。通常運転部13は、地震感知器8から各地震感知信号が入力されていなくて、かつ火災感知器10から火災感知信号が出力されていない正常状態において、各呼び登録装置11、12から入力された各呼びの指定階へのかご4の移動指令をかご移動制御部14へ送出する。かご移動制御部14は巻上機2を駆動して、かご4を指定階へ移動させる。   FIG. 2 is a block diagram illustrating a schematic configuration of the disaster operation control apparatus 3 including an information processing apparatus such as a computer provided in the machine room. The normal operation unit 13 is input from each of the call registration devices 11 and 12 in a normal state in which each earthquake detection signal is not input from the earthquake detector 8 and no fire detection signal is output from the fire detector 10. A command for moving the car 4 to the designated floor of each call is sent to the car movement control unit 14. The car movement control unit 14 drives the hoist 2 to move the car 4 to the designated floor.

地震管制運転部15は、地震感知器8から「強」の感知信号が入力されると通常運転部13へ停止指令を出力して、通常運転を解除すると共に、移動中のかご4を即時停止する信号をかご移動制御部14へ送出して、かご4を停止させる。   The seismic control operation unit 15 outputs a stop command to the normal operation unit 13 when a strong detection signal is input from the earthquake detector 8, cancels the normal operation, and immediately stops the moving car 4 A signal to be transmitted is sent to the car movement control unit 14 to stop the car 4.

地震管制運転部15は、地震感知器8から「低」の感知信号が入力されると通常運転部13へ停止指令を出力して、通常運転を解除すると共に、地震管制運転を実行する。すなわち、最寄階検出部16にて、移動中のかご4の移動方向、及びかご位置を検出して、現在位置から移動方向に隣接する階を「最寄階」とする。そして、かご4を停止せずに最寄階に移動させて当該最寄階でかごの戸開を実施して、かご4内の利用客を当該最寄階のエレベータホールへ避難させる。そして、かご4のドアを閉じて、エレベータの運転を停止して、エレベータ保守管理会社の保守員の点検、再起動待ちとなる。なお、「極低」の感知信号レベルの場合、エレベータのかご4を停止せずに最寄階に移動させる。その他は、「低」の感知信号の場合と同じである。   The seismic control operation unit 15 outputs a stop command to the normal operation unit 13 when a detection signal of “low” is input from the earthquake detector 8, cancels the normal operation, and executes the seismic control operation. That is, the nearest floor detecting unit 16 detects the moving direction and the car position of the moving car 4 and sets the floor adjacent in the moving direction from the current position as the “closest floor”. Then, the car 4 is moved to the nearest floor without stopping, and the car is opened on the nearest floor, and the passengers in the car 4 are evacuated to the elevator hall on the nearest floor. Then, the door of the car 4 is closed, the operation of the elevator is stopped, and maintenance and maintenance of the elevator maintenance management company are awaited. In the case of a “very low” sensing signal level, the elevator car 4 is moved to the nearest floor without stopping. Others are the same as in the case of the “low” sensing signal.

火災管制運転部17内には、火災発生時に、この建屋にいる人が建屋外へ避難するときに使用する出口が設けられている階が避難階として記憶されている。この実施形態においては避難階として1階(1F)が設定されている。そして、この火災管制運転部17は、何れかの階の火災感知器10からの火災感知信号が入力すると、通常運転部13へ停止指令を出力して、通常運転を解除すると共に、移動中のかご4を避難階メモリ18に記憶されている避難階へ移動させて、戸開して、かご4内の利用客をエレベータホールから建屋の外へ避難させる。   In the fire control operation unit 17, when a fire occurs, a floor provided with an exit used when a person in the building evacuates to the outside of the building is stored as an evacuation floor. In this embodiment, the first floor (1F) is set as the evacuation floor. When the fire detection signal from the fire detector 10 on any floor is input, the fire control operation unit 17 outputs a stop command to the normal operation unit 13 to cancel the normal operation and move. The car 4 is moved to the evacuation floor stored in the evacuation floor memory 18 and opened to evacuate the passengers in the car 4 from the elevator hall to the outside of the building.

重複判定部19は、地震管制運転部15による地震管制運転期間中に火災感知器10から火災階を指定した火災感知信号が入力したこと、又は火災管制運転部17による火災管制運転期間中に地震感知器8から「低」又は「極低」の地震感知信号が入力したことを検出すると、複合管制運転部20を起動する。   The duplication determination unit 19 receives an input of a fire detection signal designating a fire floor from the fire detector 10 during the earthquake control operation period by the earthquake control operation unit 15 or an earthquake during the fire control operation period by the fire control operation unit 17. When it is detected that a “low” or “very low” earthquake detection signal is input from the sensor 8, the composite control operation unit 20 is activated.

複合管制運転部20は、起動すると先ず最適選択部21にて、この複合管制運転部20が、かご4を最終的に移動させる最適階とかごの4の移動経路とを、現在実行中の管制運転における、かご4の移動方向、現在位置、最寄階、避難階、地震の強度、火災階(火災の災害を受けている階)に基づいて選択する。   When the composite control operation unit 20 is started, first, the optimal selection unit 21 causes the composite control operation unit 20 to control the optimal floor where the car 4 is finally moved and the movement route of the car 4 currently being executed. The selection is made based on the moving direction of the car 4, the current position, the nearest floor, the evacuation floor, the intensity of the earthquake, and the fire floor (the floor receiving the fire disaster) during driving.

具体的には、図5(a)に示すように、地震の強度が「低」で、かご4の移動方向が避難階方向で、かつ現在のかご位置と避難階との間に火災階が存在するとき、現在のかご位置と火災階との間の階を最適階と選択する。この場合、最寄階を最適階と指定することも可能である。なお、地震の強度が「極低」の場合は、避難階を無条件で最適階と指定する。この場合、かご4を、火災階を通過させることもある。   Specifically, as shown in FIG. 5 (a), the intensity of the earthquake is “low”, the direction of movement of the car 4 is the direction of the evacuation floor, and there is a fire floor between the current car position and the evacuation floor. When present, the floor between the current car position and the fire floor is selected as the optimal floor. In this case, it is possible to designate the nearest floor as the optimum floor. If the intensity of the earthquake is “extremely low”, the evacuation floor is unconditionally designated as the optimum floor. In this case, the car 4 may pass through the fire floor.

また、図5(b)に示すように、地震の強度が「低」で、かご4の移動方向が反避難階方向(この場合は地震管制運転中)で、かつ現在のかご位置と火災階との間に最寄階が存在するとき、かご4を最寄階に一旦停止し戸開せずに移動方向を反転し、火災階を過ぎた階を最適階と選択する。なお、地震の強度が「極低」の場合は、火災階を過ぎた階ではなく、最終の避難階を最適階と指定する。   In addition, as shown in FIG. 5 (b), the intensity of the earthquake is “low”, the moving direction of the car 4 is the anti-evacuation floor direction (in this case, during seismic control operation), and the current car position and the fire floor. When the nearest floor exists, the car 4 is temporarily stopped at the nearest floor, the moving direction is reversed without opening the door, and the floor past the fire floor is selected as the optimum floor. If the intensity of the earthquake is “extremely low”, the final evacuation floor is designated as the optimal floor, not the floor past the fire floor.

また、図5(c)に示すように、地震の強度が「低」で、かご4の移動方向が避難階方向で、かつ現在のかご位置と避難階との間に火災階が存在しないとき、最寄階を最適階と選択する。なお、地震の強度が「極低」の場合は、最寄階ではなく、最終の避難階を最適階と指定する。   In addition, as shown in FIG. 5C, when the intensity of the earthquake is “low”, the direction of movement of the car 4 is the direction of the evacuation floor, and there is no fire floor between the current car position and the evacuation floor The nearest floor is selected as the optimum floor. When the intensity of the earthquake is “extremely low”, the final evacuation floor is designated as the optimum floor, not the nearest floor.

複合管制運転部20は、最適選択部21で選択された経路に従って同じく選択された最適階にかご4を移動する指令をかご移動制御部14へ送出する。   The composite control operation unit 20 sends to the car movement control unit 14 a command to move the car 4 to the optimum floor selected in accordance with the route selected by the optimum selection unit 21.

このように構成されたエレベータの災害時運転御制御装置3は図3、図4の流れ図に従って、エレベータの運転制御を実施する。   The elevator operation control device 3 at the time of disaster of the elevator configured as described above performs the operation control of the elevator according to the flowcharts of FIGS. 3 and 4.

地震感知器8から、「低」又は「極低」の地震感知信号が入力すると(ステップS1)、現在、地震管制運転中か否かを調べて(S2)、地震管制運転中の場合はこの状態を継続する。地震管制運転中でなく、かつ火災管制運転中でなければ(S3)、地震管制運転を開始する(S4)。また、火災管制運転中の場合は(S3)、地震と火災とが同一時間帯で発生したので、図4の複合管制運転処理を実行する(S5)。   When a “low” or “very low” earthquake detection signal is input from the earthquake detector 8 (step S1), it is checked whether or not the earthquake control operation is currently being performed (S2). Continue state. If it is not in the seismic control operation and is not in the fire control operation (S3), the seismic control operation is started (S4). Further, when the fire control operation is being performed (S3), since the earthquake and the fire occurred in the same time zone, the composite control operation processing of FIG. 4 is executed (S5).

また、S6にて、火災感知器10から火災階を指定した火災感知信号が入力すると、現在、火災管制運転中か否かを調べて(S7)、火災管制運転中の場合はこの状態を継続する。火災管制運転中でなく、かつ地震管制運転中でなければ(S8)、火災管制運転を開始する(S9)。また、地震管制運転中の場合は(S8)、火災と地震とが同一時間帯で発生したので、図4の複合管制運転処理を実行する(S5)。   In addition, when a fire detection signal designating a fire floor is input from the fire detector 10 at S6, it is checked whether or not the fire control operation is currently being performed (S7), and this state is continued if the fire control operation is being performed. To do. If the fire control operation is not being performed and the earthquake control operation is not being performed (S8), the fire control operation is started (S9). Further, when the earthquake control operation is in progress (S8), since the fire and the earthquake occurred in the same time zone, the composite control operation processing of FIG. 4 is executed (S5).

なお、地震感知器8から、「強」の地震感知信号が入力した場合は、移動中のかご4を即時停止する。   When a “strong” earthquake detection signal is input from the earthquake detector 8, the moving car 4 is immediately stopped.

図4の複合管制運転処理が開始されると、先に入力された地震感知信号が「低」の場合(S11)、以下の「低」の複合管制運転を開始する(S12)。すなわち、図5(c)に示すように、最寄階と避難階との間に火災階が存在しない場合、(S13)、最寄階が最適階となり、この最寄階にかご4を停止し(S14)、戸開して(S15)、かご4内の利用者を該当階のエレベータホールへ避難させて、エレベータを運転停止させる。   When the composite control operation processing of FIG. 4 is started, if the previously input earthquake detection signal is “low” (S11), the following “low” composite control operation is started (S12). That is, as shown in FIG. 5C, when there is no fire floor between the nearest floor and the evacuation floor (S13), the nearest floor becomes the optimum floor, and the car 4 is stopped on this nearest floor. (S14), the door is opened (S15), the user in the car 4 is evacuated to the elevator hall on the floor, and the elevator is stopped.

なお、図5(a)に示すように、最寄階と避難階との間に火災階が存在する場合(S13)で、かつ、かご4の走行方向に避難階が存在する場合(S16)、現在のかご位置と火災階との間の階の一つを最適階として選択し(S17)、この最適階にかご4を停止し、戸開して(S18)、かご内の利用者を該当階のエレベータホールへ避難させて、エレベータを運転停止させる。   In addition, as shown to Fig.5 (a), when a fire floor exists between the nearest floor and an evacuation floor (S13), and an evacuation floor exists in the running direction of the cage | basket | car 4 (S16). Then, one of the floors between the current car position and the fire floor is selected as the optimum floor (S17), the car 4 is stopped on this optimum floor, the door is opened (S18), and the users in the car are selected. Evacuate the elevator hall on the floor and stop the elevator.

また、図5(b)に示すように、かご4の走行方向に避難階が存在しない場合(S16)、かご4を最寄階に一旦停止し戸開せずに移動方向を反転し(S19)、火災階を過ぎた階を最適階と選択し(S17)、この最適階にかご4を停止し、戸開して(S18)、かご内の利用者を該当階のエレベータホールへ避難させて、エレベータを運転停止させる。   Further, as shown in FIG. 5B, when there is no evacuation floor in the traveling direction of the car 4 (S16), the car 4 is temporarily stopped at the nearest floor and the moving direction is reversed without opening the door (S19). ), Select the floor past the fire floor as the optimal floor (S17), stop the car 4 on this optimal floor, open the door (S18), evacuate the users in the car to the elevator hall of the corresponding floor Stop the elevator.

また、先に入力された地震感知信号が「極低」の場合(S11)、以下の「極低」の複合管制運転を開始する(S20)。すなわち、図5(a)のように、かご4の走行方向に避難階が存在する場合(S21)、火災位置の如何に係わらず、避難階を最適階に選択して(S22)、この最適階にかご4を停止し、戸開して(S23)、かご4内の利用者を該当階のエレベータホールへ避難させて、エレベータを運転停止させる。   If the previously input earthquake detection signal is “extremely low” (S11), the following “extremely low” composite control operation is started (S20). That is, as shown in FIG. 5A, when there is an evacuation floor in the traveling direction of the car 4 (S21), the evacuation floor is selected as the optimum floor regardless of the fire position (S22). The car 4 is stopped on the floor, the door is opened (S23), the user in the car 4 is evacuated to the elevator hall on the floor, and the elevator is stopped.

また、図5(b)のように、かご4の走行方向が避難階の方向と逆の場合(S21)火災位置の如何に係わらず、かご4を最寄階に一旦停止し戸開せずに移動方向を反転し(S24)、かつ避難階を最適階と選択する(S22)。この最適階にかご4を停止し、戸開して(S23)、かご内の利用者を該当階のエレベータホールへ避難させて、エレベータを運転停止させる。   Further, as shown in FIG. 5B, when the traveling direction of the car 4 is opposite to the direction of the evacuation floor (S21), the car 4 is temporarily stopped at the nearest floor and the door is not opened regardless of the fire position. The moving direction is reversed (S24), and the evacuation floor is selected as the optimum floor (S22). The car 4 is stopped on the optimum floor, the door is opened (S23), the user in the car is evacuated to the elevator hall on the floor, and the elevator is stopped.

このように構成された第1実施形態のエレベータの災害時運転制御装置3においては、地震と火災とが同一時間帯に発生した場合は、地震管制運転と火災管制運転とが、地震と火災のうちの先に発生した順に個別に実行されたり、優先度の高い方が実行されることはなく、両者の利点を組み込んだ、新たな複合管制運転を実行するようにしている。   In the elevator operation control device 3 at the time of disaster of the first embodiment configured in this way, when an earthquake and a fire occur in the same time zone, the earthquake control operation and the fire control operation are They are not executed individually in the order in which they occur first, or the one with higher priority is not executed, and a new combined control operation incorporating the advantages of both is executed.

この場合、現在実行中の管制運転における、かご4の移動方向、現在位置、最寄階、避難階、地震の強度、火災階に基づいて、複合管制運転部20がかご4を最終的に移動させる最適階とかごの4の移動経路を選択設定している。   In this case, the combined control operation unit 20 finally moves the car 4 based on the moving direction of the car 4, the current position, the nearest floor, the evacuation floor, the intensity of the earthquake, and the fire floor in the currently running control operation. 4 movement routes of the optimum floor and the car to be selected are set.

例えば、「低」の地震発生の場合、地震によるかご4内の閉じ込めを回避することを優先して、かご4が火災階を通過したり、火災階に停止すことが避けられている。逆に、「極低」の地震発生の場合、火災からの避難を優先して、管制運転において、かご4が火災階を速度を減速せずに通過して避難階へ向かう。   For example, when a “low” earthquake occurs, priority is given to avoiding confinement in the car 4 due to the earthquake, and the car 4 is prevented from passing through the fire floor or stopping at the fire floor. Conversely, in the event of an “extremely low” earthquake, priority is given to evacuation from fire, and in control operation, the car 4 passes through the fire floor without decelerating the speed and heads for the evacuation floor.

したがって、たとえ地震と火災とが同じ時間帯に生じたとしても、地震と火災の発生状況に応じて、最適の複合管制運転が実行されるので、エレベータの利用客にとって十分に安全性が確保できる。   Therefore, even if an earthquake and a fire occur at the same time zone, the optimal combined control operation is executed according to the occurrence of the earthquake and the fire, so that sufficient safety can be secured for elevator users. .

(第2実施形態)
図6は、本発明の第2実施形態に係わるエレベータの災害時運転制御装置3の複合管制運転処理動作を示す流れ図である。なお、第2実施形態においては、全体構成図、ブロック図、全体の流れ図は前述した第1実施形態とほぼ同じであるので、説明を省略する。
(Second Embodiment)
FIG. 6 is a flowchart showing the combined control operation processing operation of the elevator disaster operation control device 3 according to the second embodiment of the present invention. In the second embodiment, the overall configuration diagram, block diagram, and overall flowchart are substantially the same as those in the first embodiment described above, and thus the description thereof is omitted.

なお、この第2実施形態のエレベータの災害時運転制御装置3においては、火災感知器10は建屋に1台のみが設置されており、火災位置は検出できない。   In the elevator disaster operation control device 3 of the second embodiment, only one fire detector 10 is installed in the building, and the fire position cannot be detected.

図3のS5において、複合管制運転処理が指定されると、図6の複合管制運転処理が開始する。   When the composite control operation process is designated in S5 of FIG. 3, the composite control operation process of FIG. 6 starts.

すなわち、先に入力された地震感知信号が「低」の場合(R1)、以下の「低」の複合管制運転を開始する(R2)。すなわち、図5(a)のように、かご4の走行方向に避難階が存在する場合(S3)、避難階を最適階に選択して、この避難階まで、かご4を低速で移動させて(R4)、この最適階にかご4を停止し、戸開して(R5)、かご4内の利用者を該当避難階のエレベータホールへ避難させて、エレベータを運転停止させる。   That is, when the previously input earthquake detection signal is “low” (R1), the following “low” combined control operation is started (R2). That is, as shown in FIG. 5A, when an evacuation floor exists in the traveling direction of the car 4 (S3), the evacuation floor is selected as the optimum floor, and the car 4 is moved to the evacuation floor at a low speed. (R4), the car 4 is stopped on this optimum floor, the door is opened (R5), the users in the car 4 are evacuated to the elevator hall of the corresponding evacuation floor, and the elevator is stopped.

また、図5(b)のように、かご4の走行方向が避難階の方向と逆の場合(R3)、かごを最寄階に一旦停止し戸開せずに移動方向を反転し(R6)、かつ避難階を最適階と選択し、この避難階(最適階)まで、かご4を低速で移動させて(R4)、この最適階(避難階)にかご4を停止し、戸開して(R5)、かご4内の利用者を該当避難階のエレベータホールへ避難させて、エレベータを運転停止させる。   Further, as shown in FIG. 5B, when the traveling direction of the car 4 is opposite to the direction of the evacuation floor (R3), the car is temporarily stopped at the nearest floor and the moving direction is reversed without opening the door (R6). ) And the evacuation floor is selected as the optimum floor, the car 4 is moved to the evacuation floor (optimum floor) at a low speed (R4), the car 4 is stopped at the optimum floor (evacuation floor), and the door is opened. (R5), the user in the car 4 is evacuated to the elevator hall on the corresponding evacuation floor, and the elevator is stopped.

また、先に入力された地震感知信号が「極低」の場合(R1)、以下の「極低」の複合管制運転を開始する(R7)。図5(a)のように、かご4の走行方向に避難階が存在する場合(R8)、避難階を最適階に選択して、この避難階まで、かご4を通常速度で移動させて(R9)、この最適階にかご4を停止し、戸開して(R10)、かご4内の利用者を該当避難階のエレベータホールへ避難させて、エレベータを運転停止させる。   If the previously input earthquake detection signal is “extremely low” (R1), the following “extremely low” composite control operation is started (R7). As shown in FIG. 5A, when an evacuation floor exists in the traveling direction of the car 4 (R8), the evacuation floor is selected as the optimum floor, and the car 4 is moved to the evacuation floor at a normal speed ( R9), the car 4 is stopped on the optimum floor, the door is opened (R10), the users in the car 4 are evacuated to the elevator hall on the evacuation floor, and the elevator is stopped.

また、図5(b)のように、かご4の走行方向が避難階の方向と逆の場合(R8)、かごを最寄階に一旦停止し戸開せずに移動方向を反転し(R11)、かつ避難階を最適階と選択し、この避難階まで、かご4を通常速度で移動させて(R9)、この最適階(避難階)にかご4を停止し、戸開して(R10)、かご4内の利用者を該当避難階のエレベータホールへ避難させて、エレベータを運転停止させる。   Further, as shown in FIG. 5B, when the traveling direction of the car 4 is opposite to the direction of the evacuation floor (R8), the car is temporarily stopped at the nearest floor and the moving direction is reversed without opening the door (R11). ) And the evacuation floor is selected as the optimum floor, the car 4 is moved to the evacuation floor at a normal speed (R9), the car 4 is stopped on the optimum floor (evacuation floor), and the door is opened (R10). ), Evacuate the user in the car 4 to the elevator hall on the corresponding evacuation floor, and stop the elevator operation.

このように構成された第2実施形態のエレベータの災害時運転制御装置3においても、地震と火災とが同じ時間帯に生じた場合においては、地震の強度に応じて、かご4が避難階(最適階)へ移動する速度を変更している。したがって、前述した第1実施形態のエレベータの災害時運転制御装置3とほぼ同じ効果を奏することが可能である。   Also in the elevator operation control device 3 at the time of disaster of the elevator of the second embodiment configured in this way, when the earthquake and the fire occur in the same time zone, the car 4 is evacuated to the evacuation floor (according to the intensity of the earthquake ( The speed to move to the optimal floor is changed. Accordingly, it is possible to achieve substantially the same effect as the elevator disaster operation control device 3 of the first embodiment described above.

(第3実施形態)
図7は、本発明の第3実施形態に係わるエレベータの災害時運転制御装置3が組込まれたエレベータの昇降路1内に設置された、吊り合い錘5を上下方向にガイドする一対のレール7a、7bを示す斜視図である。
(Third embodiment)
FIG. 7 shows a pair of rails 7a for vertically guiding a suspension weight 5 installed in an elevator hoistway 1 in which an elevator disaster operation control device 3 according to a third embodiment of the present invention is incorporated. , 7b.

この一対のレール7a、7bの上方位置には、例えば地震の揺れによって、吊り合い錘5がレール7a、7bから外れたことを、例えばレーザ光線で検出するレール外れ検出部22a、22bが設けられている。エレベータにおけるのその他の構成は図1に示す第1実施形態のエレベータとほぼ同じである。   At the upper position of the pair of rails 7a and 7b, there are provided rail out-of-rail detection units 22a and 22b for detecting, for example, with a laser beam that the suspended weight 5 has come off from the rails 7a and 7b due to, for example, an earthquake. ing. Other configurations of the elevator are substantially the same as those of the elevator according to the first embodiment shown in FIG.

このレール外れ検出部22a、22bは吊り合い錘5がレール7a、7bから外れると、レール外れ信号を機械室に設けられた図8に示す災害時運転制御装置3の複合管制運転部20aへ送出する。複合管制運転部20a内の最適階選択部21aは、複合管制運転において、かご4を移動させて戸開する最適階を、実行中の管制運転におけるかご位置と、このかご位置と移動方向と地震又は火災の情報と、かご位置と吊り合い錘5との位置関係とに基づいて選択する。   When the suspended weight 5 is disengaged from the rails 7a and 7b, the rail disengagement detection units 22a and 22b send out a rail disengagement signal to the composite control operation unit 20a of the disaster operation control device 3 shown in FIG. 8 provided in the machine room. To do. The optimal floor selection unit 21a in the composite control operation unit 20a determines the optimal floor that is opened by moving the car 4 in the composite control operation, the car position in the current control operation, the car position, the moving direction, and the earthquake. Alternatively, the selection is made on the basis of fire information and the positional relationship between the car position and the suspension weight 5.

具体的には、図10(a)に示す吊り合い錘5がレール7a、7b内にいる正常状態から、図10(b)に示す吊り合い錘5がレール7a、7bから外れた状態において、かご4が上下移動する過程において、かご4とレール7a、7bから外れた状態の吊り合い錘5とが重なる重なり階(一般に中央階、エレベータに固有の値)に、かご4が位置したり、通過することを回避するように、最適階を設定する。   Specifically, in a state where the suspension weight 5 shown in FIG. 10 (a) is in the rails 7a and 7b, the suspension weight 5 shown in FIG. 10 (b) is detached from the rails 7a and 7b. In the process in which the car 4 moves up and down, the car 4 is located on an overlapping floor (generally a value unique to the central floor and the elevator) where the car 4 and the suspended weight 5 that has been removed from the rails 7a and 7b overlap. The optimal floor is set so as to avoid passing.

図9は、本発明の第3実施形態に係わるエレベータの災害時運転制御装置3における、地震と火災とが同一時間帯に発生した場合における、複合管制運転部20aが行う複合管制運転処理を示す流れ図である。   FIG. 9 shows composite control operation processing performed by the composite control operation unit 20a when an earthquake and a fire occur in the same time zone in the elevator operation control device 3 at the time of disaster according to the third embodiment of the present invention. It is a flowchart.

図3のS5において、複合管制運転処理が指定されると、図9の複合管制運転処理が開始する。   When the composite control operation process is designated in S5 of FIG. 3, the composite control operation process of FIG. 9 starts.

すなわち、先に入力された地震感知信号が「低」の場合(Q1)、レール外れ検出部22a、22bからレール外れ信号が入力されていない場合は(Q2)、Q3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。また、レール外れ検出部22a、22bからレール外れ信号が入力された場合は(Q2)、Q4にて、かご4が避難階に到達するまでに、重なり階が存在しなければ、Q3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。   That is, when the earthquake detection signal input earlier is “low” (Q1), and when no rail disconnection signal is input from the rail disconnection detection units 22a and 22b (Q2), in Q3, R2 in FIG. The "low" combined control operation indicated by R6 is performed. In addition, when a rail out signal is input from the rail out detector 22a, 22b (Q2), if there is no overlapping floor before the car 4 reaches the evacuation floor in Q4, in Q3 6 “Low” combined control operation indicated by R2 to R6 is performed.

さらに、Q4にて、図10(b)に示すように、かご4が避難階に到達するまでに、重なり階が存在すると、かご4が重なり階に到達するまでの間で、避難階に最も近い階を最適階とする(Q5)。その後、Q3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。この場合、最適階を避難階に置き換える。   Furthermore, at Q4, as shown in FIG. 10 (b), if there is an overlapping floor before the car 4 reaches the evacuation floor, the most evacuation floor is reached until the car 4 reaches the overlapping floor. The nearest floor is the optimum floor (Q5). Thereafter, in Q3, the “low” composite control operation indicated by R2 to R6 in FIG. 6 is performed. In this case, the optimum floor is replaced with an evacuation floor.

また、先に入力された地震感知信号が「極低」の場合(Q1)、地震の揺れは極く弱いので、レール外れは発生しないと見なして、レール外れの有無を調べることなく、図6のR7〜R11で示した、「極低」の複合管制運転を実施する。   In addition, when the earthquake detection signal input earlier is “extremely low” (Q1), since the earthquake shake is extremely weak, it is considered that the rail does not come off, and without checking the presence or absence of the rail, FIG. The "ultra-low" composite control operation indicated by R7 to R11 is performed.

このように構成された第3実施形態のエレベータの災害時運転制御装置3においては、地震時には、地震の揺れの影響で吊り合い錘5がレール7a、7bから外れることも想定できる。このような場合においても、エレベータを即時に停止することなく、乗客の安全性を十分確保した条件で、可能な限り、かご4を避難階に近づけて停止している。したがって、利用客に対する安全性をより一層向上できる。   In the emergency operation control device 3 for an elevator according to the third embodiment configured as described above, it can be assumed that the suspended weight 5 is detached from the rails 7a and 7b due to the influence of the shaking of the earthquake during an earthquake. Even in such a case, the car 4 is stopped as close as possible to the evacuation floor as much as possible under the condition that passenger safety is sufficiently secured without stopping the elevator immediately. Therefore, the safety for users can be further improved.

(第4実施形態)
図11は、本発明の第4実施形態に係わるエレベータの災害時運転制御装置3が組込まれたエレベータの昇降路1内に設置された、吊り合い錘5を上下方向にガイドする一対のレール7a、7bを示す斜視図である。
(Fourth embodiment)
FIG. 11 shows a pair of rails 7a for vertically guiding a suspension weight 5 installed in an elevator hoistway 1 in which an elevator disaster operation control device 3 according to a fourth embodiment of the present invention is incorporated. , 7b.

この一対のレール7a、7bの上方位置には、例えば地震の揺れによって、レール7a、7bに例えば図14(b)に示すように、曲がり26が発生したことを、例えばレーザ光線で検出するレーザ検出器23a,23bが設置されている。さらに、各レール7a,7bの側方には、発生した曲がり26の上下方向の位置を例えばレーザスキャン方式で検出する位置検出器24a、24bが設置されている。したがって、レーザ検出器23a,23bと位置検出器24a、24bとは、レール7a、7bにおける曲がり26の発生と発生位置とを検出する図12に示すレール曲がり検出部25を構成する。   At the upper position of the pair of rails 7a and 7b, for example, a laser that detects, for example, by a laser beam, the occurrence of a bend 26 in the rails 7a and 7b as shown in FIG. Detectors 23a and 23b are installed. Further, position detectors 24a and 24b for detecting the vertical position of the generated bending 26 by, for example, a laser scanning method are installed on the sides of the rails 7a and 7b. Therefore, the laser detectors 23a and 23b and the position detectors 24a and 24b constitute a rail bend detector 25 shown in FIG. 12 that detects the occurrence and occurrence position of the bend 26 in the rails 7a and 7b.

レール曲がり検出部25は、レール7a、7bにおける曲がり26の発生と発生位置とを検出すると、この曲がり26の発生位置を付した曲がり発生信号を機械室に設けられた図12に示す災害時運転制御装置3の複合管制運転部20bへ送出する。複合管制運転部20b内の最適階選択部21bは、複合管制運転において、かご4を移動させて戸開する最適階を、実行中の管制運転におけるかご位置と、このかご位置と移動方向と地震又は火災の情報と、かご位置とレール曲がり位置との位置関係とに基づいて選択する。   When the rail bend detection unit 25 detects the occurrence and occurrence position of the bend 26 in the rails 7a and 7b, the bend occurrence signal with the occurrence position of the bend 26 is provided in the machine room at the time of disaster shown in FIG. It is sent to the composite control operation unit 20b of the control device 3. The optimal floor selection unit 21b in the composite control operation unit 20b determines the car position in the control operation being performed, the car position, the moving direction, and the earthquake in the composite control operation. Alternatively, the selection is made based on fire information and the positional relationship between the car position and the rail bending position.

具体的には、図14(a)に示すレール7a、7bが正常状態から、図14(b)に示すレール7a、7bに曲がり26が生じた状態において、かご4が上下移動する過程において、このかご4に連動して、移動する吊り合い錘5が、曲がり26位置に留まったり、通過することを回避するように、かご4の最適階を設定する。この場合、吊り合い錘5の位置とかご4の位置とは1対1で対応するので、かご4の停止及び通過禁止の階は一義的に定まる。   Specifically, in the process in which the car 4 moves up and down in the state where the rails 7a and 7b shown in FIG. 14 (a) are in a normal state and the rails 7a and 7b shown in FIG. 14 (b) are bent 26, In conjunction with the car 4, the optimum floor of the car 4 is set so that the moving suspension weight 5 is prevented from staying at or passing through the position of the bend 26. In this case, since the position of the suspension weight 5 and the position of the car 4 correspond one-to-one, the floor where the car 4 is stopped and prohibited from passing is uniquely determined.

図13は、本発明の第4実施形態に係わるエレベータの災害時運転制御装置3における、地震と火災とが同一時間帯に発生した場合における、複合管制運転部20bが行う複合管制運転処理を示す流れ図である。   FIG. 13 shows the composite control operation processing performed by the composite control operation unit 20b when an earthquake and a fire occur in the same time zone in the elevator operation control device 3 at the time of disaster according to the fourth embodiment of the present invention. It is a flowchart.

図3のS5において、複合管制運転処理が指定されると、図13の複合管制運転処理が開始する。すなわち、先に入力された地震感知信号が「低」の場合(U1)、レール曲がり検出部25から曲がり位置を指定したレール曲がり信号が入力されていない場合は(U2)、U3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。また、レール曲がり検出部25から曲がり位置を指定したレール曲がり信号が入力さた場合は(U2)、U3にて、かご4が避難階に到達するまでに、吊り合い錘5がレール7a、7bの曲がり26位置を通過又は停止しない場合は(U4)、U3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。   When the composite control operation process is designated in S5 of FIG. 3, the composite control operation process of FIG. 13 starts. That is, when the earthquake detection signal input earlier is “low” (U1), or when the rail bending signal designating the bending position is not input from the rail bending detection unit 25 (U2), in FIG. The low control operation indicated by R2 to R6 in FIG. When a rail bend signal specifying a bend position is input from the rail bend detection unit 25 (U2), the suspended weight 5 is moved to the rails 7a and 7b until the car 4 reaches the evacuation floor at U3. In the case of not passing or stopping at the position 26 of the turn (U4), in U3, the "low" composite control operation indicated by R2 to R6 in FIG. 6 is performed.

さらに、U4にて、図14(b)に示すように、かご4が避難階に到達するまでに、吊り合い錘5がレール7a、7bの曲がり26位置を通過又は停止すると、この吊り合い錘5がレール7a、7bの曲がり26位置に到達する手前に停止する許容範囲を求める(U5)。そして、吊り合い錘5の停止位置に対応するかご4の停止できる階を、新規の最適階とする(U6)。その後、U3において、図6のR2〜R6で示した、「低」の複合管制運転を実施する。この場合、最適階を避難階に置き換える。   Furthermore, at U4, as shown in FIG. 14B, when the suspension weight 5 passes or stops at the position 26 of the rails 7a and 7b before the car 4 reaches the evacuation floor, the suspension weight An allowable range in which 5 stops before reaching the position 26 of the rails 7a and 7b (U5) is obtained. Then, the floor at which the car 4 corresponding to the stop position of the suspension weight 5 can be stopped is set as a new optimum floor (U6). Thereafter, in U3, the “low” composite control operation indicated by R2 to R6 in FIG. 6 is performed. In this case, the optimum floor is replaced with an evacuation floor.

また、先に入力された地震感知信号が「極低」の場合(U1)、地震の揺れは極く弱いので、レールの曲がり26は発生しないと見なして、レール曲がりの有無を調べることなく、U7において、図6のR7〜R11で示した、「極低」の複合管制運転を実施する。   In addition, when the earthquake detection signal input earlier is “ultra low” (U1), the vibration of the earthquake is extremely weak, so it is considered that the rail bending 26 does not occur, and the presence or absence of the rail bending is examined. At U7, the “ultra-low” composite control operation indicated by R7 to R11 in FIG. 6 is performed.

このように構成された第4実施形態に係わるエレベータの災害時運転制御装置3においては、地震時には、地震の揺れの影響で吊り合い錘5のレール7a、7bに曲がり26が生じることも想定できる。このような場合においても、エレベータを即時に停止することなく、乗客の安全性を十分確保した条件で、可能な限り、かご4を避難階に近づけて停止している。したがって、利用客に対する安全性をより一層向上できる。   In the emergency operation control device 3 for an elevator according to the fourth embodiment configured as described above, it can be assumed that, during an earthquake, bending 26 occurs in the rails 7a and 7b of the suspended weight 5 due to the influence of the shaking of the earthquake. . Even in such a case, the car 4 is stopped as close as possible to the evacuation floor as much as possible under the condition that passenger safety is sufficiently secured without stopping the elevator immediately. Therefore, the safety for users can be further improved.
