次に、上記構成を有するエレベータ装置において、地震発生後に実施される地震復旧運転の動作について説明する。図３はこの発明の実施の形態１におけるエレベータの地震復旧運転装置の動作を示すフローチャートである。
図において、エレベータ１号機及び２号機における通常運転の実施時に地震が発生すると、地震時管制運転が実施される。具体的には、まず地震感知器等を介してエレベータ装置に地震発生情報が入力され、かご３ａ及び３ｂが昇降路内で緊急停止させる。次に乗客がかご３ａ及び３ｂに閉じ込められて缶詰状態になることを防ぐため最寄階に停止して所定時間戸開状態が維持し、かご３及び３ａ内に乗客がいなくなったことを秤装置等よって検出する。これにより診断運転開始条件が成立する。ここで地震管制運転が実施されるとき、地震の程度（ｇａｌ）により昇降路内で緊急停止せず、そのまま最寄階に走行する動作の場合もある。
次に診断運転開始条件が成立するとエレベータ装置は走行音異常診断を開始する（ＳＴ１）。具体的には、まずエレベータかご３ａ及び３ｂをそれぞれ近接する一方の終端階の乗場まで走行させた後、それそれのかごを他端の終端階まで低速移動させながら、集音マイク９ａ及び９ｂによる異常音の検出に基づいて昇降路１内やかご３ａ及び３ｂ等に設置されたエレベータ１号機、及び２号機の各種機器類の動作の診断をする。
次に集音マイク９ａ及び９ｂで集音された集音レベル判定を行う（ＳＴ２）。具体的には判定回路Ｂ１７が変換回路Ｂ１３から入力された集音レベル値と、判定値記録部Ｂ１８に設定された異常音レベルの判定値との比較を行う。次に集音レベル判定（ＳＴ２）時において集音レベル値が異常音レベルの判定値以上の場合（ＳＴ３）、隣接号機との位置判定（ＳＴ４）を行う。具体的には判定回路Ａ１５が、上述した条件Ａ以内、つまりエレベータ１号機のかご３ａとエレベータ２号機のかご３ｂ所定距離以内で近接（すれ違っている）時であるかの判定する（ＳＴ５）。
次に条件Ａ以外の場合、異常音ありと判定され（ＳＴ６）走行音異常診断運転は失敗となり同時にエレベータの地震復旧運転も終了する。また条件Ａ以内の場合は異常音ありの判定は無効され集音レベル判定（ＳＴ２）に戻る。 Next, the operation of the earthquake recovery operation performed after the occurrence of the earthquake in the elevator apparatus having the above configuration will be described. FIG. 3 is a flowchart showing the operation of the elevator earthquake recovery operation apparatus according to Embodiment 1 of the present invention.
In the figure, when an earthquake occurs during normal operation in the elevator No. 1 and No. 2, an earthquake control operation is carried out. Specifically, first, earthquake occurrence information is input to the elevator apparatus via an earthquake detector or the like, and the cars 3a and 3b are urgently stopped in the hoistway. Next, in order to prevent the passengers from being trapped in the cars 3a and 3b and being in a canned state, it is stopped at the nearest floor and the open state is maintained for a predetermined time, and it is determined that there are no passengers in the cars 3 and 3a. Etc. Thereby, the diagnostic operation start condition is satisfied. Here, when the seismic control operation is carried out, there is a case of an operation of traveling to the nearest floor as it is without emergency stop in the hoistway depending on the magnitude (gal) of the earthquake.
Next, when the diagnostic operation start condition is satisfied, the elevator apparatus starts a running sound abnormality diagnosis (ST1). Specifically, the elevator cars 3a and 3b are first moved to the landing on one terminal floor adjacent to each other, and then the cars are slowly moved to the terminal floor on the other end while the sound collecting microphones 9a and 9b are used. Based on the detection of the abnormal sound, the operation of the elevators No. 1 and No. 2 installed in the hoistway 1 and the cars 3a and 3b is diagnosed.
Next, the sound collecting level collected by the sound collecting microphones 9a and 9b is determined (ST2). Specifically, the determination circuit B17 compares the sound collection level value input from the conversion circuit B13 with the determination value of the abnormal sound level set in the determination value recording unit B18. Next, when the sound collection level value is equal to or higher than the determination value of the abnormal sound level at the time of sound collection level determination (ST2) (ST3), position determination (ST4) with the adjacent car is performed. Specifically, the determination circuit A15 determines whether it is within the above-mentioned condition A, that is, when it is close (passing) within a predetermined distance within the car 3a of the elevator 1 and the car 3b of the elevator 2 (ST5).
Next, in a case other than the condition A, it is determined that there is an abnormal sound (ST6), and the traveling sound abnormality diagnosis operation fails, and at the same time, the earthquake restoration operation of the elevator is ended. If the condition is within the condition A, the determination that there is an abnormal sound is invalidated and the process returns to the sound collection level determination (ST2).

この発明の実施の形態１によれば、かご３ａ及び３ｂが昇降路１内を昇降するエレベータ装置において、地震復旧運転の走行音異常診断運転時、隣接する他号機のかごが所定距離以内に接近しているときの異常音を無効とできるため、該他号機の走行音もしくは異常音を自号機の異常音とする誤検知を防ぐことができる。また地震復旧運転の精度を高めることができる。また複数台のエレベータ装置を同時に地震復旧運転することが可能となるため、地震復旧運転完了までの時間を短縮することができる。   According to the first embodiment of the present invention, in the elevator apparatus in which the cars 3a and 3b move up and down in the hoistway 1, the car of the adjacent other car approaches within a predetermined distance during the traveling sound abnormality diagnosis operation in the earthquake restoration operation. Since the abnormal sound at the time of running can be invalidated, it is possible to prevent erroneous detection in which the traveling sound or abnormal sound of the other car is used as the abnormal sound of the own car. In addition, the accuracy of earthquake recovery operation can be increased. In addition, since it is possible to simultaneously perform the earthquake recovery operation of a plurality of elevator apparatuses, it is possible to shorten the time until the earthquake recovery operation is completed.

また特別な装置を追加する必要もないため、上記地震復旧運転を実施させるためのプログラム等を既設のエレベータ装置に付加したりすることにより、現在稼動中のエレベータ装置に対しても容易に対応することが可能である。   In addition, since it is not necessary to add a special device, it is possible to easily cope with an elevator device that is currently in operation by adding a program for performing the earthquake recovery operation to the existing elevator device. It is possible.

実施の形態２
実施の形態１における地震復旧運転（診断運転）においては、隣接号機のかごが所定距離以内で近接するときにおいて、集音された異常音を無効とする運転としたが、本実施の形態２においては、他号機のかご、及び釣合錘の位置関係を判断し、他号機のかご及び釣合錘の位置が自号機のかご位置から所定距離以内で近接している場合は異常音の検知を無効とする。ここで釣合錘の位置は昇降行程とかご位置から算出する。これにより、実施の形態１と同様の効果を得るとともに、釣合錘の走行音を異常音とする誤検知も防ぐことができ、地震復旧運転の精度を高めることができる。 Embodiment 2
In the earthquake restoration operation (diagnostic operation) in the first embodiment, when the car of the adjacent car approaches within a predetermined distance, the collected abnormal sound is invalidated. However, in the second embodiment, Determines the positional relationship between the car of the other car and the counterweight, and detects the abnormal sound when the car of the other car and the counterweight are close to each other within a predetermined distance from the car position of the own car. Invalid. Here, the position of the counterweight is calculated from the lifting stroke and the car position. Thereby, while obtaining the same effect as Embodiment 1, it can also prevent the false detection which makes the running sound of a counterweight an abnormal sound, and can raise the precision of an earthquake restoration driving | operation.

実施の形態３
図４はこの発明の実施の形態３におけるエレベータの地震復旧運転（診断運転）を示すフローチャートである。
本実施の形態３においては、実施の形態１及び実施の形態２のエレベータの地震復旧装置に以下の機能を追加したものである。すなわち複数台のエレベータ装置の地震復旧運転（診断運転）を実施する場合、予めそれぞれ号機に優先度を設け、自号機のかごまたは釣合錘と隣接号機のかごまたは釣合錘との距離が所定距離以内となった場合、優先度が低い号機はかごの走行を停止し、診断運転を一時中断する。また優先度の低い号機は優先度の高い隣接号機のかご位置及び釣合錘位置が所定距離以上となった時、走行を再開し、走行音異常診断を再開するものである。これにより隣接号機との干渉による異常音の誤検出を防止できる。 Embodiment 3
FIG. 4 is a flowchart showing an earthquake recovery operation (diagnostic operation) of an elevator according to Embodiment 3 of the present invention.
In the third embodiment, the following functions are added to the elevator earthquake restoration apparatus of the first and second embodiments. That is, when performing earthquake restoration operation (diagnostic operation) of multiple elevator devices, each car is given priority in advance, and the distance between the car or counterweight of its own car and the car or counterweight of the adjacent car is predetermined. If it is within the distance, the car with the lower priority stops running the car and suspends the diagnostic operation. In addition, the low-priority car restarts running and the running noise abnormality diagnosis when the car position and counterweight position of the neighboring car with high priority exceeds a predetermined distance. This can prevent erroneous detection of abnormal sounds due to interference with adjacent cars.

図４のフローチャートに従って動作説明を行う。ここで本フローチャートは、エレベータ１号機を例に、該エレベータ１号機がエレベータ２号機より地震復旧運転（診断運転）による復旧の優先度が低い設定として説明を行う。
まず実施の形態１と同様、地震時管制運転が完了後、診断運転開始条件が成立すると走行音異常診断を開始する。次に隣接号機との位置判定（ＳＴ１）を行う。具体的には判定回路Ａ１５が、上述した条件Ａ以内、つまりエレベータ１号機のかご３ａ又は釣合錘４ａとエレベータ２号機のかご３ｂまたは釣合錘４ｂが判定値記録部Ｂ１８に保存された所定距離以内で近接（すれ違っている）時であるかの判定する（ＳＴ２）。
まず、判定結果が条件Ａ以内の場合について説明する。条件Ａ以内の場合、優先度の高いエレベータ２号機の診断運転に影響を及ぼす為、優先度の低いエレベータ１号機の診断運転中断指令（ＳＴ３）が出力され、一旦エレベータ１号機のかご３ａを停止させる。これにより、復旧の優先度が高いエレベータ２号機の診断運転を優先させる。次にエレベータ１号機のかご３ａ及び釣合錘４ａとエレベータ２号機のかご３ｂとの位置関係の判定を繰り返し（ＳＴ１、ＳＴ２）、これらの位置関係が条件Ａ以外となった場合、診断運転中判定（ＳＴ４）へ進む。ここで既に条件Ａ以内の判定（ＳＴ２）でエレベータ１号機の診断運転は一時中断しかご３ａは停止しているため、診断運転中判定（ＳＴ４）から運転再開指令出力（ＳＴ５）へ進む。これによりエレベータ１号機は診断運転を再開し、再度エレベータ２号機との位置判定（ＳＴ１）を行い、条件Ａ以外の判定（ＳＴ２）により診断運転中判定（ＳＴ４）へと進む。
次にエレベータ２号機との位置判定（ＳＴ１）が条件Ａ以外の場合について説明する。条件Ａ以外の場合は、復旧を優先するエレベータ２号機の診断運転に影響を及ぼす恐れがない為、エレベータ１号機の診断運転は中断せずかご３ａは走行を続け診断運転中の判定（ＳＴ４）へと進む。
次に診断運転中の判定（ＳＴ４）では、エレベータ１号機のかご３ａが走行しているかの判定を行い、走行中の場合は、集音レベルの判定（ＳＴ６）へ進む。
集音レベルの判定（ＳＴ６）では、判定回路Ｂ１７が変換回路Ｂ１３から入力される集音レベル値と判定値記録部Ｂ１８に記録された異常音レベルの判定値と比較を行い（ＳＴ７）、判定値以上の場合は異常音ありの検出（ＳＴ８）へ進み診断運転を中断させる。 The operation will be described according to the flowchart of FIG. Here, in the flowchart, the elevator No. 1 is taken as an example, and the explanation will be made assuming that the priority of restoration by the earthquake restoration operation (diagnostic operation) of the elevator No. 1 is lower than that of the elevator No. 2.
First, as in the first embodiment, after the control operation at the time of earthquake is completed, when the diagnosis operation start condition is satisfied, the running sound abnormality diagnosis is started. Next, position determination (ST1) with the adjacent car is performed. More specifically, the determination circuit A15 has a predetermined value stored in the determination value recording unit B18 within the above condition A, that is, the elevator car 3a or counterweight 4a and the elevator car 2b or counterweight 4b. It is determined whether it is close (passing) within a distance (ST2).
First, a case where the determination result is within the condition A will be described. If it is within the condition A, it will affect the diagnostic operation of the elevator 2 with higher priority, so the diagnostic operation interruption command (ST3) of the elevator 1 with lower priority will be output, and the elevator 3 car 3a will be stopped once Let This gives priority to the diagnostic operation of the elevator No. 2 that has a high recovery priority. Next, the determination of the positional relationship between the elevator car 1a and the counterweight 4a and the elevator car 2b is repeated (ST1, ST2). Proceed to determination (ST4). Here, since the diagnosis operation of the elevator No. 1 has already been temporarily suspended by the determination within the condition A (ST2), the car 3a has stopped temporarily, so the process proceeds from the diagnosis operation determination (ST4) to the operation restart command output (ST5). As a result, the elevator No. 1 restarts the diagnostic operation, performs the position determination (ST1) with the elevator No. 2 again, and proceeds to the determination during the diagnostic operation (ST4) by the determination other than the condition A (ST2).
Next, the case where the position determination (ST1) with the elevator No. 2 is other than the condition A will be described. In conditions other than A, there is no possibility of affecting the diagnostic operation of the elevator No. 2 that prioritizes restoration, so the diagnostic operation of the elevator No. 1 is not interrupted and the car 3a continues to run and is determined to be in the diagnostic operation (ST4) Proceed to
Next, in the determination during the diagnostic operation (ST4), it is determined whether the car 3a of the elevator No. 1 is traveling, and if it is traveling, the process proceeds to the sound collection level determination (ST6).
In the sound collection level determination (ST6), the determination circuit B17 compares the sound collection level value input from the conversion circuit B13 with the determination value of the abnormal sound level recorded in the determination value recording unit B18 (ST7). If it is equal to or greater than the value, the process proceeds to detection of abnormal noise (ST8) and the diagnostic operation is interrupted.

これにより、実施の形態１及び実施の形態２と同様の効果を得るとともに、エレベータのそれぞれの号機に優先度を設けたため、地震発生後のエレベータの優先号機の使用開始を早めることが可能である。   As a result, the same effects as those of the first and second embodiments are obtained, and since priority is provided to each elevator unit, it is possible to speed up the start of use of the elevator priority unit after the occurrence of an earthquake. .
