Description

本発明は、エレベータのドア開閉異常を検出した結果に基づいて対応を判断するエレベータ用ドア開閉異常判定装置に関する。   The present invention relates to an elevator door opening / closing abnormality determining apparatus that determines a response based on a result of detecting an elevator door opening / closing abnormality.
従来、一般にエレベータのドア廻りには、利用者が乗りかごに備えられるかごドアに挟まれないように安全装置が取り付けられており、安全装置の動作状態が一定条件を満たすとドア開閉異常があるとみなしてエレベータの運転休止や遠隔監視装置による担当拠点への出動発報を行うようになっている。   Conventionally, a safety device is generally installed around an elevator door so that a user is not caught by a car door provided in the car. If the operating state of the safety device satisfies a certain condition, there is a door opening / closing abnormality. It is considered that the operation of the elevator is suspended and dispatched to the responsible site by a remote monitoring device.
ところが、エレベータのドア開閉異常の原因の多くは異物の挟み込みや人為的な悪戯等でドア開閉を妨げるものであり、こうした場合にもエレベータを運転休止してしまうと利用者に多大な迷惑を与えるだけでなく、遠隔監視装置による出動発報が行われると保全作業員にも負担を掛けることになるため、利用者への迷惑や保全作業員の負担を低減する目的で異物の挟み込みや人為的なドア開閉異常発生時には状況を判断してエレベータが運転休止される前に対応する機能が必要とされている。   However, many of the causes of elevator door opening / closing abnormalities are obstructing the door opening / closing due to foreign object pinching or artificial mischief, etc. Even in such a case, if the elevator is shut down, it causes great inconvenience to the user. Not only that, but dispatching a remote monitoring device will place a burden on maintenance workers, so foreign objects may be trapped or man-made for the purpose of reducing inconvenience to users and the burden on maintenance workers. When an abnormal opening / closing of a door occurs, a function is required to determine the situation and respond before the elevator is shut down.
このような対応機能を具現するには、ドア開閉異常の発生時にドア廻りの状況から原因を分析して対応方法を判断する必要があり、こうした関連技術も提案されている。例えばドアに異常が発生してドアの反転動作が繰り返されたとき、ドアの異常発生を早期に取り除くことを目的とする「エレベータドア異常状態報知装置」(特許文献1参照)が挙げられる。   In order to implement such a response function, it is necessary to determine the response method by analyzing the cause from the situation around the door when a door opening / closing abnormality occurs, and such a related technique has also been proposed. For example, there is an “elevator door abnormal state notification device” (see Patent Document 1) for the purpose of removing an abnormal occurrence of a door at an early stage when an abnormality occurs in the door and the reverse operation of the door is repeated.
特開平5−43175号公報JP-A-5-43175
上述した特許文献1記載の技術は、ドアの動作状態(反転回数)により異物の挟み込みを検知したときに利用者に異物除去をアナウンスする機能を持たせたものであるが、実際には異物によるドア開閉異常の発生以外の人為的に発生しているドア開閉異常を的確に判断することができないため、人為的に発生しているドア開閉異常を含めてアナウンス自体を的確な指示内容で行い、迅速にドア開閉異常の回避を対処できないという問題がある。   The technique described in Patent Document 1 described above provides a user with a function of announcing the removal of a foreign object when it is detected that the foreign object has been caught by the operating state (number of inversions) of the door.

Depending on the result of determining the situation, the announcement device 11 has a function of making announcements with different announcement contents.
図2は、上述したエレベータシステムの制御装置6により参照されるアナウンス内容の選択条件を登録したデータベースの内容を例示した概略図である。因みに、ここでのデータベースは制御装置6に内蔵されるものとするが、その他に外部記憶部10に持たせるようにすることも可能である。   FIG. 2 is a schematic diagram illustrating the contents of a database in which the selection conditions for the announcement contents referred to by the control device 6 of the elevator system described above are registered. Incidentally, the database here is assumed to be built in the control device 6, but it is also possible to have the database in the external storage unit 10.
一般に、エレベータのドア開閉異常を発生する要因は様々であり、それらの要因に対してそれぞれ動作する安全装置の動作条件が決まっている。本実施例では、安全装置の動作状態やかご内防犯カメラ9により撮影された乗りかご1内のかごドア8の状況に着目し、ドア開閉異常が発生した際のアナウンス内容を判断する。例えば、安全装置の動作状態としてドアセフティシュスイッチ(SW)が一定時間以上OFFを継続している情報、並びにかご内防犯カメラ9による映像情報でかごドア8付近に人がいる場合の情報を参照し、ドア開閉異常の状況を判別した結果として、ドア付近の人がセフティシュSWをOFFし続けていると判断すれば、アナウンス内容としてドアを押さえるのを止める旨のアナウンスを行えば、的確なアナウンスとなる。これにより、利用者によるドア開閉異常検出に伴うエレベータの運転休止の回避対処を迅速に実行できるようになり、他の利用者への迷惑や保全作業員の出動負担を低減することができる。   In general, there are various factors that cause abnormalities in elevator door opening and closing, and the operating conditions of the safety device that operates for each of these factors are determined. In this embodiment, paying attention to the operating state of the safety device and the situation of the car door 8 in the car 1 taken by the in-car security camera 9, the contents of the announcement when the door opening / closing abnormality occurs are determined. For example, refer to the information that the door safety switch (SW) has been turned OFF for a certain time or more as the operating state of the safety device, and the information when there is a person near the car door 8 by the video information from the in-car security camera 9 If it is determined that the person in the vicinity of the door continues to turn off the safety switch as a result of determining the abnormal state of the door opening / closing, if an announcement is made to stop pressing the door as an announcement content, Announcement. As a result, it is possible to quickly execute the avoidance measures for the suspension of the elevator operation accompanying the detection of the door opening / closing abnormality by the user, and it is possible to reduce the trouble to other users and the burden of dispatching maintenance workers.
図2を参照して安全装置の動作状態とかご内防犯カメラ9の映像内容とによりアナウンス内容を判別する条件を説明すれば、第1番目(No.1)の条件は荷物運搬時等で乗りかご1のかごドア8が閉まらないように人が意図的にセフティシュSWをOFFにしている場合である。かごドア8の全開状態を維持するためには、全開状態でセフティシュSWをOFFにする必要があり、このために人が手や足を使ってセフティシュSWをOFFにする必要がある。そこで、セフティシュSWのOFF継続時間とかご内防犯カメラ9の映像でかごドア8廻りの人の有無とを参照し、具体的には安全装置動作状態として「セフティシュSWが10秒以上OFF」であり、かご内防犯カメラ9映像が「ドア廻りに人がいる」結果であれば、アナウンス内容として「ドアを押さえるのを止めて下さい」なる旨のアナウンスを行うことを示している。即ち、こうした場合の制御装置6は、かごドア制御情報がドア全開状態であり、且つ安全装置の動作状態としてセフティシュSWが所定時間以上継続して動作していると共に、撮像情報(映像情報)がドア廻りに人が映っていることを示している場合のドア開閉異常の状況の判別結果に際して、アナウンス装置11に指示してアナウンス内容としてセフティシュSWの操作を中止する旨をアナウンスすることになる。   Referring to FIG. 2, the conditions for determining the announcement contents based on the operation state of the safety device and the video contents of the in-car security camera 9 will be described. This is a case where the person intentionally turns off the safety switch so that the car door 8 of the car 1 is not closed. In order to maintain the fully open state of the car door 8, it is necessary to turn off the safety SW in the fully open state. For this reason, it is necessary for a person to turn off the safety SW using hands or feet. Therefore, referring to the OFF duration of the safety SW and the presence / absence of a person around the car door 8 in the image of the security camera 9 in the car, specifically, “Safety SW is OFF for 10 seconds or more” as the safety device operating state. If the image of the security camera 9 in the car is a result of “There are people around the door”, it indicates that the announcement is “Please stop pressing the door”. That is, in such a case, the control device 6 has the car door control information in the fully opened state, and the safety SW operates continuously for a predetermined time or more as the operation state of the safety device, and the imaging information (video information). When the door opening / closing abnormality determination result indicates that a person is reflected around the door, the announcement device 11 is instructed to announce that the operation of the safety SW is to be stopped as the announcement content. Become.
また、第2番目(No.2)の条件は乗りかご1のかごドア8が開閉する線上に物(物体)が置いてあり、かごドア8が開閉を繰り返している場合である。かごドア8の開閉線上に物が置いてあり、かごドア8が開閉を繰り返す場合には、かごドア8が閉方向に動作しているときにセフティシュSWがOFFし、かごドア8が開方向に動作することを繰り返す必要がある。そこで、かごドア8が全開するまでのセフティシュSWがOFFした回数とかご内防犯カメラ9の映像でかごドア8廻りの物の有無とを参照し、具体的には安全装置動作状態として「ドア全開までにセフティシュSWが5回以上OFF」であり、かご内防犯カメラ9映像が「ドア開閉線上に物がある」結果であれば、アナウンス内容として「出入り口に物を置かないで下さい」なる旨のアナウンスを行うことを示している。即ち、こうした場合の制御装置6は、かごドア制御情報がドア全開状態であり、且つ安全装置の動作状態としてセフティシュSWが所定回数以上繰り返し動作していると共に、撮像情報(映像情報)がドア廻りに物体が映っていることを示している場合のドア開閉異常の状況の判別結果に際して、アナウンス装置11に指示してアナウンス内容として物体の存在とその物体の除去を依頼する旨をアナウンスすることになる。   The second (No. 2) condition is a case where an object (object) is placed on a line where the car door 8 of the car 1 opens and closes and the car door 8 is repeatedly opened and closed. When an object is placed on the open / close line of the car door 8 and the car door 8 is repeatedly opened and closed, the safety SW is turned OFF when the car door 8 is moving in the closing direction, and the car door 8 is opened. Need to repeat to work. Therefore, the number of times the safety SW is turned OFF until the car door 8 is fully opened and the presence / absence of objects around the car door 8 in the video of the in-car security camera 9 are referred to. If the safety switch is OFF more than 5 times before it is fully opened, and the in-car security camera 9 video results in “There is something on the door opening / closing line”, the announcement will be “Please do not place anything at the doorway” This indicates that an announcement to this effect will be made. That is, in such a case, the control device 6 is such that the car door control information is in the fully opened state, and the safety SW is repeatedly operated more than a predetermined number of times as the operation state of the safety device, and the imaging information (video information) is the door. When the door opening / closing abnormality determination result indicates that an object is reflected around, the announcement device 11 is instructed to announce the presence of the object and the request to remove the object as the announcement content. become.
更に、第3番目(No.3)の条件は乗りかご1又は乗場の敷居溝に異物が挟まっており、かごドア8が開閉を繰り返している場合である。敷居溝に異物が挟まっていることでかごドア8が開閉を繰り返す場合には、かごドア8が閉方向に動作しているときにセフティシュSWがON状態で安全装置の乗員保護装置(ORS)が動作し、かごドア8が開方向に動作することを繰り返す必要がある。また、かご内防犯カメラ9の映像でドア開閉線上に異物がないことを確認する必要である。そこで、セフティシュSWがON状態でかごドア8が全閉するまでの安全装置の乗員保護装置(ORS)の動作回数とかご内防犯カメラ9の映像でかごドア8廻りの人又は物体の有無とを参照し、具体的には安全装置動作状態として「セフティシュSWがON状態でドア全閉までにORSが5回以上動作」であり、かご内防犯カメラ9映像が「ドア開閉線上に物や人がない」結果であれば、アナウンス内容として「敷居のゴミを取り除いて下さい」なる旨のアナウンスを行うことを示している。即ち、こうした場合の制御装置6は、かごドア制御情報がドア全開状態であり、且つ安全装置の動作状態としてセフティシュSWが所定回数以上繰り返し動作していると共に、撮像情報(映像情報)がドア廻りに人又は物体が映っていないことを示している場合のドア開閉異常の状況の判別結果に際して、アナウンス装置11に指示してアナウンス内容として敷居溝の異物の除去を依頼する旨をアナウンスすることになる。因みに、ドア開閉線上に物や人がないことの確認は、例えば乗りかご1が無人である状態で予め撮影したかごドア8が開閉する線上の基準映像と撮影した映像とを比較したときの画像差分等により容易に検出することが可能である。   Furthermore, the third (No. 3) condition is when a foreign object is caught in the car 1 or the sill groove of the hall, and the car door 8 is repeatedly opened and closed. When the car door 8 repeatedly opens and closes due to foreign matter being caught in the sill groove, the safety switch is in the ON state when the car door 8 is operating in the closing direction, and the occupant protection device (ORS) of the safety device It is necessary to repeatedly operate the car door 8 in the opening direction. In addition, it is necessary to confirm that there is no foreign object on the door opening / closing line by the image of the car security camera 9. Therefore, the number of operations of the occupant protection device (ORS) of the safety device until the car door 8 is fully closed while the safety switch is ON, and the presence or absence of people or objects around the car door 8 based on the video of the in-car security camera 9 Specifically, the safety device operating state is “the safety switch is ON and the ORS is operated more than 5 times until the door is fully closed”, and the car security camera 9 video is “the object on the door opening / closing line” If the result is “no people”, it is indicated that the announcement “please remove trash on the threshold” is made as an announcement. That is, in such a case, the control device 6 is such that the car door control information is in the fully opened state, and the safety SW is repeatedly operated more than a predetermined number of times as the operation state of the safety device, and the imaging information (video information) is the door. When it is determined that there is no person or object in the surroundings and the result of the door opening / closing abnormality determination result, the announcement device 11 is instructed to announce the request to remove foreign matter in the sill groove as an announcement content. become. Incidentally, the confirmation that there is no object or person on the door opening / closing line is, for example, an image obtained by comparing a reference image on the line opened / closed by the car door 8 with the car 1 unoccupied in advance and a photographed image. It can be easily detected by a difference or the like.
図3は、上述したエレベータシステムの制御装置6によるアナウンス内容の選択を含む動作処理を示したフローチャートである。   FIG. 3 is a flowchart showing an operation process including selection of announcement contents by the control device 6 of the elevator system described above.
図3を参照すれば、制御装置6の動作処理では、最初にかごドア制御装置7からの昇降機(乗りかご1)のかごドア8についてのかごドア制御情報(安全装置の動作状況を含む)とかご内防犯カメラ9からのかご内カメラ映像(映像情報)の抽出(ステップS1)を行った後、次に図2を参照して説明したデータベースにアナウンス内容選択条件と一致する情報はあるか否かの判定(ステップS2)を行う。この判定の結果、アナウンス内容選択条件と一致する情報がなければ、最初の昇降機のかごドア制御情報とかご内カメラ映像の抽出(ステップS1)の処理の前に戻って処理を繰り返すが、アナウンス内容選択条件と一致する情報があれば、乗りかご1内のアナウンス装置11へ指示して選択条件と一致するアナウンス内容をアナウンスすることでかご内にアナウンス(ステップS3)する処理を行った後、再度アナウンス内容選択条件と一致する情報はあるか否かの判定(ステップS4)を行う。この判定の結果、アナウンス内容選択条件と一致する情報がなければ、最初の昇降機のかごドア制御情報とかご内カメラ映像の抽出(ステップS1)の処理の前に戻って処理を繰り返すが、アナウンス内容選択条件と一致する情報があれば、遠隔監視装置12に指示して通信回線網20を介して外部回線14を経由して担当拠点13に出動発報を行うようにして、各拠点に出動発報(ステップS5)する処理を行ってから動作処理を終了する。これにより、各担当拠点13では、係るエレベータシステムのドア開閉異常の発生状況を把握でき、適切な対処を行うことができる。   Referring to FIG. 3, in the operation process of the control device 6, first, car door control information (including the operation status of the safety device) about the car door 8 of the elevator (car 1) from the car door control device 7. After extracting the in-car camera image (image information) from the in-home security camera 9 (step S1), whether there is information that matches the announcement content selection condition in the database described with reference to FIG. (Step S2). As a result of this determination, if there is no information that matches the announcement content selection condition, the process returns to before the first elevator car door control information and in-car camera image extraction (step S1) process, and the process is repeated. If there is information that matches the selection condition, the announcement device 11 in the car 1 is instructed to announce the contents of the announcement that matches the selection condition, and then the process of making an announcement (step S3) in the car is performed again. It is determined whether there is information that matches the announcement content selection condition (step S4). As a result of this determination, if there is no information that matches the announcement content selection condition, the process returns to before the first elevator car door control information and in-car camera image extraction (step S1) process, and the process is repeated. If there is information that matches the selection condition, the remote monitoring device 12 is instructed to dispatch to the assigned site 13 via the communication line network 20 and the external line 14, so that each site is dispatched.
