Description

この発明は、地震発生後に地震管制運転で停止しているエレベータにおいて、基準階（通常は１階）の戸開閉に異常がないかどうかを診断し、異常がなければ、エレベータを地震管制モードから復帰させて、各階戸開閉診断運転モードにするエレベータの戸開閉異常監視装置に関するものである。   This invention diagnoses whether there is any abnormality in the door opening / closing of the standard floor (usually the first floor) in an elevator that has been stopped by seismic control operation after the occurrence of an earthquake. The present invention relates to an elevator door opening / closing abnormality monitoring apparatus that is restored to enter each door opening / closing diagnosis operation mode.

従来、エレベータの戸開閉自動チェック装置においては、戸の開閉を制御する戸開閉制御装置と、乗りかごを所定の階に移動させ、戸開閉制御装置に戸開閉動作をさせ、戸開閉動作時間が所定の設定時間以上であった場合に当該階を戸開閉異常と判断するテスト手段と、テスト手段を予め設定された日時に実施させる起動手段とを備え、夜間等の利用客がいない予め予約された時間帯に、自動的に戸開閉動作をチェックするものが知られている（例えば、特許文献１参照）。
また、定められたプログラムに基づいて自動的に診断運転をするエレベータの自動診断装置において、診断内容を独立した複数の診断項目（例えば、戸開閉動作点検、ブレーキ保持力点検など）に分けて、可能な時に各々の診断項目毎に診断運転をするという従来技術が知られている（例えば、特許文献２参照）。 Conventionally, in an elevator door opening / closing automatic check device, a door opening / closing control device that controls opening / closing of the door, a car is moved to a predetermined floor, the door opening / closing control device performs door opening / closing operation, and the door opening / closing operation time is It is equipped with a test means for determining that the floor is abnormally open / closed when it is longer than a predetermined set time, and an activation means for executing the test means at a preset date and time, and reserved in advance without passengers such as at night. A device that automatically checks the door opening / closing operation during a certain time period is known (see, for example, Patent Document 1).
In addition, in an elevator automatic diagnosis device that automatically performs diagnostic operation based on a predetermined program, the diagnosis contents are divided into a plurality of independent diagnosis items (for example, door opening / closing operation inspection, brake holding force inspection, etc.) A conventional technique is known in which diagnostic operation is performed for each diagnostic item when possible (see, for example, Patent Document 2).

特開２０００−２７２８５６号公報JP 2000-272856 A 特開２００２−３１１５号公報JP 2002-3115 A

従来のエレベータの戸開閉自動チェック装置では、予め設定された時間帯に、自動的に戸開閉診断運転を実施しているが、地震発生後に地震管制運転で停止しているエレベータを如何様に戸開閉診断運転を実施し、如何にして自動復旧に結び付けるかという点についてまでは述べられていない。また、特許文献２に記載されたものも、例えば、戸開閉動作点検において、診断運転プログラムがエレベータ制御装置からの動作回数情報とインターバルが一致したと判断した場合には診断運転を開始するものであり、地震発生後に地震管制運転で停止しているエレベータを如何様に戸開閉診断運転を実施し、如何にして自動復旧に結び付けるかという点についてまでは述べられていない。   In conventional elevator door opening / closing automatic check devices, door opening / closing diagnosis operation is automatically performed during a preset time period, but how can elevators that are stopped by earthquake control operation after an earthquake occur? There is no mention of how to perform open / close diagnostic operation and how it is linked to automatic recovery. Also, the one described in Patent Document 2 starts diagnostic operation when, for example, in the door opening / closing operation inspection, the diagnostic operation program determines that the interval coincides with the operation frequency information from the elevator control device. There is no mention of how to perform door opening / closing diagnosis operation for elevators that have been stopped by seismic control operation after the occurrence of an earthquake, and how to link them to automatic recovery.

この発明は、上述のような課題を解決するためになされたもので、正常時の戸開閉トルク・戸開閉時間を予め記憶しておき、地震発生後に地震管制運転で停止しているエレベータにおいて、基準階（通常は１階）の戸開閉トルク・戸開閉時間点検運転を自動で実施し、異常がなければ、エレベータを地震管制モードから復帰させて、各階戸開閉診断運転モードにするエレベータの戸開閉異常監視装置を提供するものである。   This invention was made in order to solve the problems as described above, and stores the door opening / closing torque and door opening / closing time in a normal state in advance, and in an elevator stopped by an earthquake control operation after the occurrence of an earthquake, Elevator doors that automatically perform door opening / closing torque / door opening / closing time check operation on the standard floor (usually the first floor), and if there is no abnormality, return the elevator from the seismic control mode and enter each door open / close diagnosis operation mode. An open / close abnormality monitoring apparatus is provided.

この発明に係るエレベータの戸開閉異常監視装置においては、地震発生後に地震管制運転で停止しているエレベータの戸開閉異常監視装置であって、正常時の戸開閉トルク又は戸開閉時間等を予め記憶しておき、地震発生後の戸開閉トルク又は戸開閉時間等と正常時のそれとを比較する戸開閉点検運転を実施し、基準階における戸開閉診断に異常がなければエレベータを地震管制モードから復帰させて、各階戸開閉診断運転モードにするものである。   The elevator door opening / closing abnormality monitoring apparatus according to the present invention is an elevator door opening / closing abnormality monitoring apparatus that has been stopped by an earthquake control operation after the occurrence of an earthquake, and stores the door opening / closing torque or the door opening / closing time in a normal state in advance. The door opening / closing inspection operation that compares the door opening / closing torque or the door opening / closing time after the earthquake with the normal one is conducted, and if there is no abnormality in the door opening / closing diagnosis on the standard floor, the elevator is returned from the earthquake control mode. Thus, each floor door opening / closing diagnosis operation mode is set.

また、各階戸開閉診断運転モード中、エレベータの呼びが無い場合は、自動でエレベータのかごを戸開閉診断未実施の階に走行させて、戸開閉診断を行うものである。   When there is no elevator call in each door opening / closing diagnosis operation mode, the elevator car is automatically run to a floor where the door opening / closing diagnosis has not been performed to perform door opening / closing diagnosis.

また、各階戸開閉診断運転モード中、エレベータの呼びがあった場合は、呼びに応答してエレベータのかごを呼びがあった階に走行させ、呼びがあった階が戸開閉診断未実施の際は戸開閉診断を行い、戸開閉診断を実施した階の場合は戸開閉診断を行わないものである。   In addition, if there is an elevator call in each floor door opening / closing diagnosis operation mode, the elevator car is driven to the floor where the call was made in response to the call, and the floor where the call was made has not been opened or closed. The door opening / closing diagnosis is performed, and the door opening / closing diagnosis is not performed for the floor where the door opening / closing diagnosis is performed.

また、各階戸開閉診断運転を繰り返して全階正常と判断された場合は、各階戸開閉診断運転モードを解除し、エレベータを通常動作に復帰させるものである。   Further, when each floor door opening / closing diagnosis operation is repeated and it is determined that all floors are normal, each floor door opening / closing diagnosis operation mode is canceled and the elevator is returned to the normal operation.

この発明によれば、地震発生後に地震管制運転で停止しているエレベータにおいて、エレベータの戸開閉の異常を検出し、全階で戸開閉正常と判断された場合は、各階戸開閉診断モードを解除し、通常動作へと移行することができる。また、基準階以外の階の戸開閉確認を自動復旧後に行うことで、復旧診断運転時間の大幅な短縮が見込まれるという効果がある。   According to the present invention, in an elevator that is stopped by an earthquake control operation after the occurrence of an earthquake, the door opening / closing abnormality of the elevator is detected, and when it is determined that the door opening / closing is normal on all floors, each door opening / closing diagnosis mode is canceled. Then, it is possible to shift to normal operation. In addition, by performing door opening / closing confirmation on floors other than the standard floor after automatic restoration, there is an effect that the restoration diagnosis operation time can be greatly shortened.

1 is a system configuration diagram showing an elevator door opening / closing abnormality monitoring apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a flowchart for explaining the operation of the elevator door opening / closing abnormality monitoring apparatus according to Embodiment 1 of the present invention. It is.

図１において、１はエレベータの戸開閉制御装置、２はエレベータの制御盤、３は制御盤２内に設けられたエレベータ制御装置、４は巻上機、５はエレベータのかご、６はつり合いおもり、７は乗場ボタンである。予め戸開閉装置１にて戸の開閉診断に必要な正常時の数値（戸開閉トルク・戸開閉時間等）を測定するか、或いは戸開閉制御装置の機種毎に固有の数値を設定し、制御盤２内のエレベータ制御装置３に記憶しておくものである。   In FIG. 1, 1 is an elevator door opening / closing control device, 2 is an elevator control panel, 3 is an elevator control device provided in the control panel 2, 4 is a hoisting machine, 5 is an elevator car, and 6 is a counterweight. , 7 are landing buttons. Measure the normal values (door opening / closing torque, door opening / closing time, etc.) necessary for the door opening / closing diagnosis with the door opening / closing device 1 in advance, or set the numerical values unique to each type of door opening / closing control device and control This is stored in the elevator control device 3 in the panel 2.

次に、地震発生後に地震管制運転で停止しているエレベータにおいて、エレベータの戸開閉の異常を検出し、正常なら通常動作に復帰させるために戸開閉診断を実施する場合の動作フローについて、図２により説明する。
予め戸開閉装置１にて戸の開閉診断に必要な正常時の数値、すなわち正常時の戸開閉トルク・戸開閉時間等を測定するか、或いは戸開閉制御装置の機種毎に固有の正常時の数値を設定し、制御盤２内のエレベータ制御装置３に記憶しておく。地震が発生すると、地震感知器（図示せず）が感知し（ステップＳ１）、地震管制運転が動作してかご５を最寄階に停止する（ステップＳ２）。その後、診断運転開始条件を満たした場合、エレベータ制御装置３から巻上機４に走行指令が伝わり、かご５を基準階（通常は１階）へ移動させる（ステップＳ３）。基準階で戸開閉診断運転を行い、戸開閉制御装置１にて戸開閉診断に必要な地震後の数値、すなわち地震後の戸開閉トルク・戸開閉時間等を測定し（ステップＳ４）、測定された地震後の戸開閉トルク・戸開閉時間等がエレベータ制御装置３に予め記憶されていた数値よりも増加していた場合は、戸開閉異常と判断し（ステップＳ５）、基準階が戸開閉異常と判断された場合は直ちにエレベータを走行できない状態にする（ステップＳ６）。しかし、ステップＳ５で基準階が戸開閉正常と判断された場合は、エレベータの地震管制モードから復帰（解除）させ、各階戸開閉診断モードに移行する（ステップＳ７）。これにより、自動復旧が可能となる。各階戸開閉診断モード中は、以下の条件で各階の戸開閉トルク・戸開閉時間の点検運転を自動で実施する。先ず、ステップＳ８でエレベータの呼び（乗場ボタン７が押されることで登録される乗場呼び及びかご内階床ボタンが押されることで登録されるかご呼び）があるか否かを判断する。呼び登録が無い場合は、自動でエレベータのかご５を戸開閉診断未実施階に走行させ（ステップＳ９）、戸開閉診断を実施する（ステップＳ１０）。ステップＳ１１で戸開閉診断正常と判断されると、次に、ステップＳ１２に進み全階戸開閉診断が実施済みか否かを判断し、全階戸開閉診断が実施済みとなるまで上記ステップＳ８〜Ｓ１２を繰り返し行うことになる。ステップＳ１２で全階戸開閉診断が実施され、全階正常と判断された場合は、各階戸開閉診断モードを解除し、通常動作へと移行する（ステップＳ１３）。ステップＳ１１で戸開閉診断異常と判断された場合は、戸開閉異常モード（例えば、エレベータを走行できない状態又は異常発生階のみ非停止状態）とする（ステップＳ１４）。
また、ステップＳ８でエレベータの呼び登録があった場合は、呼びに応答してエレベータのかご５を呼び登録階に走行させ（ステップＳ１５）、停止した登録階は戸開閉診断が実施済み階かあるか否かを判断する（ステップＳ１６）。ステップＳ１６で停止階が戸開閉診断未実施階であれば戸開診断を実施し（ステップＳ１７）、乗客の乗降を実施し（ステップＳ１８）、戸閉診断を実施した後（ステップＳ１９）、上記ステップＳ１１に進む。一方、ステップＳ１６で停止階が戸開閉診断実施済み階であれば戸開閉診断は行わないで戸開し（ステップＳ２０）、乗客の乗降を実施し（ステップＳ２１）、戸閉した後（ステップＳ２２）、ステップＳ８に戻る。 Next, in an elevator that has been stopped by an earthquake control operation after the occurrence of an earthquake, an operation flow for detecting an elevator door opening / closing abnormality and performing a door opening / closing diagnosis to return to normal operation if normal is shown in FIG. Will be described.
The normal value necessary for the door opening / closing diagnosis in the door opening / closing device 1 is measured in advance, that is, the door opening / closing torque and the door opening / closing time in the normal state, or the normal state specific to each model of the door opening / closing control device. Numerical values are set and stored in the elevator control device 3 in the control panel 2. When an earthquake occurs, an earthquake detector (not shown) senses (step S1), and the seismic control operation operates to stop the car 5 at the nearest floor (step S2). Thereafter, when the diagnosis operation start condition is satisfied, a traveling command is transmitted from the elevator control device 3 to the hoisting machine 4, and the car 5 is moved to the reference floor (usually the first floor) (step S3). The door opening / closing diagnosis operation is performed on the reference floor, and the door opening / closing control device 1 measures the post-earthquake values necessary for the door opening / closing diagnosis, that is, the door opening / closing torque and door opening / closing time after the earthquake (step S4). If the door opening / closing torque, door opening / closing time, etc. after the earthquake has increased from the values stored in the elevator control device 3 in advance, it is determined that the door opening / closing abnormality has occurred (step S5), and the reference floor has the door opening / closing abnormality. If it is determined that the elevator is not ready to travel (step S6). However, when it is determined in step S5 that the reference floor is normally open / closed, the elevator is returned (released) from the earthquake control mode, and the process proceeds to each door open / close diagnosis mode (step S7). Thereby, automatic recovery is possible. During the door opening / closing diagnosis mode, the inspection operation of the door opening / closing torque and door opening / closing time of each floor is automatically performed under the following conditions. First, in step S8, it is determined whether there is an elevator call (a hall call registered when the hall button 7 is pressed and a car call registered when the car inner floor button is pressed). When there is no call registration, the elevator car 5 is automatically run to the floor where the door opening / closing diagnosis is not performed (step S9), and the door opening / closing diagnosis is performed (step S10). If it is determined in step S11 that the door opening / closing diagnosis is normal, the process proceeds to step S12, where it is determined whether or not all floor door opening / closing diagnosis has been performed, and steps S8 to S8 are performed until the all floor door opening / closing diagnosis has been performed. S12 will be repeated. If all floor door opening / closing diagnosis is carried out in step S12 and it is determined that all floors are normal, each floor door opening / closing diagnosis mode is canceled and the routine proceeds to normal operation (step S13). If it is determined in step S11 that the door opening / closing diagnosis is abnormal, the door opening / closing abnormality mode is set (for example, the state where the elevator cannot travel or only the abnormal floor is not stopped) (step S14).
If there is an elevator call registration in step S8, the elevator car 5 is moved to the call registration floor in response to the call (step S15), and the stopped registration floor is a floor on which door opening / closing diagnosis has been performed. Whether or not (step S16). In step S16, if the stop floor is a floor where door opening / closing diagnosis has not been performed, door opening diagnosis is performed (step S17), passenger boarding / exiting is performed (step S18), and door closing diagnosis is performed (step S19). Proceed to step S11. On the other hand, if the stop floor is the floor where the door opening / closing diagnosis has been performed in step S16, the door opening / closing diagnosis is not performed (step S20), passengers get on and off (step S21), and the door is closed (step S22). ), The process returns to step S8.

以上のように、地震発生後に地震管制運転で停止しているエレベータにおいて、エレベータの戸開閉の異常を検出し、全階で戸開閉正常と判断された場合は、各階戸開閉診断モードを解除し、通常動作へと移行することができる。また、基準階以外の階の戸開閉確認を自動復旧後に行うことで、復旧診断運転時間の大幅な短縮が見込まれるという効果がある。   As described above, in elevators that have stopped due to seismic control after the occurrence of an earthquake, if an elevator door opening / closing abnormality is detected and it is determined that door opening / closing is normal on all floors, each door opening / closing diagnostic mode is canceled. , Can move to normal operation. In addition, by performing door opening / closing confirmation on floors other than the standard floor after automatic restoration, there is an effect that the restoration diagnosis operation time can be greatly shortened.
