Abstract

<P>PROBLEM TO BE SOLVED: To facilitate maintenance and inspection work in elevators installed side by side, and to maintain the reliability of an emergency operation function during the maintenance and inspection work. <P>SOLUTION: An emergency operation start signal detection device 1 issues an emergency operation start signal based on information about a power failure, an earthquake or a fire sent from a building where the elevators are installed. The emergency operation start signal is transmitted through input sections 3a-c to emergency operation function valid/invalid determination sections 4a-c. When the determination sections 4a-c determine that the emergency operation function is invalid, this is notified by reminder notification sections 6a-c. When emergency operation invalid time measuring sections 7a-c determine that the emergency operation function invalidness is continued for a certain period of time, alert notification sections 8a-c are operated to issue alerts, and also notify them to a centralized elevator control center through a communication line. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、エレベーターの管制運転装置に係り、特に複数台のエレベーターを併設した場合の管制運転装置であって、保守点検時等における装置の改良に関するものである。   The present invention relates to a control operation device for an elevator, and more particularly, to a control operation device in the case where a plurality of elevators are provided, and relates to an improvement of the device at the time of maintenance and inspection.

一般にエレベーターは、乗り場呼び及びかご内の行き先呼びに応じて運転し、複数台のエレベーターを並設した設備では、上記乗り場呼びを共通にして運転する場合が多い。このような通常の運転の外、エレベーターを設置した建屋側の停電、火災、或いは地震等に対しては、利用客の安全を優先すべく、管制運転装置も装備されている。   In general, an elevator is operated according to a landing call and a destination call in a car, and in a facility in which a plurality of elevators are arranged in parallel, the above-mentioned landing call is often operated in common. In addition to such normal operation, a control operation device is also installed to prioritize the safety of users for power outages, fires, earthquakes, etc. on the building side where the elevator is installed.

このような管制運転は、主に建屋側の災害に起因するため、複数台のエレベーターに対する指令（例えば、火災、地震、停電等は建屋側からの指令）は共通で、各エレベーターは一斉に管制運転に入ることで安全性を確保している。   Since such control operation is mainly caused by a disaster on the building side, commands for multiple elevators (for example, commands from the building side for fire, earthquake, power outage, etc.) are common, and each elevator is controlled all at once. Safety is ensured by driving.

一方、エレベーター設備は、その安全性を維持するために、定期的に保守・点検作業が行われている。このような保守点検作業時には、管制運転機能の点検も実施される。この場合、管制運転の前記性格から、並設エレベーターは一斉に管制運転に入ることになる。また、保守点検時は、様々な点検作業を行う必要上、一時的に管制運転を制限したい場合等があるが、この場合は、建屋側からの信号に応じた管制運転を一時的に無効にすることが考えられる。   On the other hand, elevator facilities are regularly maintained and inspected to maintain their safety. During such maintenance and inspection work, the control operation function is also checked. In this case, due to the above-mentioned nature of the control operation, the parallel elevators enter the control operation all at once. In addition, during maintenance inspections, it may be necessary to temporarily perform control operations due to the necessity of performing various inspections. In this case, however, control operations in response to signals from the building are temporarily disabled. It is possible to do.

他方、保守点検時等には、安全スイッチ類を一時的に無効にすることがあるが、作業終了後には直ぐに解除しておかないと危険である。そこで、このような場合には、安全スイッチ類が無効にされていることを報知するとともに、一定時間後には自動的に解除することで、解除忘れを防止することが特許文献１に記載されている。   On the other hand, safety switches may be temporarily disabled during maintenance inspections, etc., but it is dangerous if they are not released immediately after the work is completed. Therefore, in such a case, Patent Document 1 describes that forgetting to release is prevented by notifying that the safety switches are disabled and automatically releasing after a certain time. Yes.

特開平７−２７７６２６号公報JP-A-7-277626

エレベーター保守点検時に管制運転機能を一時的に無効とした場合、その解除を忘れると、前期安全スイッチ類と同様に危険である。そこで、前記特許文献１と同様に、一定時間経過後に自動解除することも考えられる。   If the control operation function is temporarily disabled at the time of elevator maintenance and inspection, if it is forgotten to release it, it is as dangerous as the safety switches in the previous period. Therefore, as in the case of Patent Document 1, it may be considered to automatically cancel after a lapse of a certain time.

しかしながら、複数台のエレベーターを並設した建屋は一般に高階床の場合が多く、保守点検作業が長くなることも多いことから、管制運転の無効設定を自動的に解除すると、逆に安全性に欠けるという問題があった。加えて、並設エレベーター全台の管制運転を一斉に無効にすると、個別に管制運転の点検を行うことが難しいという問題もあった。   However, buildings with multiple elevators arranged side by side are generally high-floor floors, and maintenance and inspection work often takes a long time. Therefore, automatically canceling the invalid setting of control operation results in lack of safety. There was a problem. In addition, there is a problem that it is difficult to individually check the control operation if the control operation of all the elevators in parallel is disabled at once.

本発明は、上記問題に鑑みてなされたもので、その目的とするところは並設エレベーターにおける管制運転の保守点検作業を容易にすることにある。
本発明の他の目的は、保守点検作業に伴う管制運転機能の信頼性を維持することにある。 The present invention has been made in view of the above problems, and an object thereof is to facilitate maintenance and inspection work of control operation in a parallel elevator.
Another object of the present invention is to maintain the reliability of the control operation function associated with maintenance and inspection work.

前記目的を達成するための本発明の特徴は、管制運転開始信号に応じて上記複数台のエレベーターを管制運転するものにおいて、上記管制運転開始信号に応じた管制運転を、エレベーターごとに無効にする手段を備えたことにある。
前記他の目的を達成するための本発明の他の特徴は、管制運転を無効にした後の経過時間を計測し、当該経過時間が一定時間以上になったことを警告報知、特に、通信回線を介してエレベーター集中管理センターへ通報する手段を備えたところにある。 A feature of the present invention for achieving the above object is that the control operation according to the control operation start signal is invalidated for each elevator in the control operation of the plurality of elevators according to the control operation start signal. There is a means.
Another feature of the present invention for achieving the other object is to measure an elapsed time after invalidating the control operation, and to notify a warning that the elapsed time has reached a certain time or more, in particular, a communication line. There is a means to report to the elevator central control center via

本発明によれば、一斉に管制運転される並設エレベーターに対して、個別にその管制運転を無効に出来るので、個別のエレベーターの保守点検に対する管制運転の制約を少なくする事が出来、並設エレベーターの保守点検作業を容易にすることができる。
更には、管制運転を無効とした後の解除忘れ防止策として、一定時間経過後に自動解除されることによる作業時間の制約受けず、安心して保守点検作業を行うことができると共に、解除忘れに対しては自動的に警報され、特にエレベーター集中管理センターでの管理も可能となることから、保守点検作業の便宜に伴う管制運転機能の信頼性低下を招くことはない。 According to the present invention, since it is possible to invalidate the control operation individually for the parallel elevators that are controlled at the same time, it is possible to reduce the restriction of the control operation for the maintenance and inspection of the individual elevators. Maintenance and inspection work of the elevator can be facilitated.
Furthermore, as a measure to prevent forgetting to release after invalidating the control operation, maintenance and inspection work can be performed with peace of mind, without being restricted by work time due to automatic release after a certain period of time. The system is automatically alerted and can be managed at the elevator centralized control center, so the reliability of the control operation function associated with the convenience of maintenance and inspection work will not be reduced.

以下、この発明の実施の形態を、図示する一実施例を用いて説明する。なお、本実施例では並設するエレベーター台数は３台とし、管制運転としては、通常の停電、地震、火災等を想定した管制運転を例に挙げて説明するが、これらに限定されるものでない。   Hereinafter, an embodiment of the present invention will be described with reference to an illustrated example. In this embodiment, the number of elevators installed side by side is three, and the control operation will be described by taking an example of control operation assuming normal power outages, earthquakes, fires, etc., but is not limited thereto. .

図１に、本発明の一実施例に係る、並設エレベーターにおける管制運転の機能ブロック図を示す。管制運転開始信号検出装置１は、エレベーターが設置された建屋からの停電、地震、或いは火災等の情報から、管制運転開始信号を発生する。   FIG. 1 shows a functional block diagram of control operation in a side-by-side elevator according to an embodiment of the present invention. The control operation start signal detection device 1 generates a control operation start signal from information such as a power failure, an earthquake, or a fire from the building where the elevator is installed.

この管制運転開始信号は、並設されたエレベーター３台の各エレベーター制御装置２ａ〜ｃに送信され、管制運転開始信号入力部３ａ〜ｃで受信される。管制運転開始信号入力部３ａ〜ｃで受信した信号は、管制運転機能有効無効判定部４ａ〜ｃに送信され、外部入力装置（例えば、保守装置、又は図３の操作盤１６）により管制運転機能が無効にされていなければ、判定部４ａ〜ｃで有効と設定されて、管制運転実行部５ａ〜ｃに送信される。これにより、３台のエレベーターは一斉に管制運転を開始する。外部入力装置により管制運転機能が無効と設定されていれば、判定部４ａ〜ｃが無効と判定し、管制運転実行部５ａ〜ｃに送信されず、管制運転は実行されない。   This control operation start signal is transmitted to each of the three elevator control devices 2a to 2c arranged in parallel, and is received by the control operation start signal input units 3a to 3c. The signals received by the control operation start signal input units 3a to 3c are transmitted to the control operation function validity / invalidity determination units 4a to 4c, and are controlled by an external input device (for example, the maintenance device or the operation panel 16 in FIG. 3). If is not invalidated, it is set as valid by the determination units 4a to 4c, and is transmitted to the control operation execution units 5a to 5c. As a result, the three elevators start control operation all at once. If the control operation function is set to be invalid by the external input device, the determination units 4a to 4c are determined to be invalid and are not transmitted to the control operation execution units 5a to 5c, and the control operation is not executed.

このように本実施例では、管制運転機能有効無効判定部４ａ〜ｃがエレベーター制御装置２ａ〜ｃごとに設けられていることからも明らかなように、エレベーターごとに管制運転の有効又は無効を設定する事ができる。   As described above, in this embodiment, the control operation valid / invalid determination units 4a to 4c are provided for each elevator control device 2a to 2c, and the control operation is set to valid or invalid for each elevator. I can do it.

管制運転機能が無効と設定されると、判定部４ａ〜ｃで無効と判定し、注意喚起報知部６ａ〜ｃより管制運転機能が無効中であることを視覚的・聴覚的に明示する指令が出力される。また、管制運転無効時間計測部７ａ〜ｃは、管制運転機能無効が一定時間継続していると判断した場合、警告報知部８ａ〜ｃ作動する。これにより、管制運転無効の解除が忘れられている可能性があることを周囲に警告すると共に、通信回線を介して、エレベーター集中管理センターに報知する。従って、周囲に保守作業員がいれば注意を喚起され、周囲にいない場合であっても、エレベーター集中管理センターで常時管理されているので、保守作業員による解除作業を確実に促すことができる。   When the control operation function is set to be invalid, the determination unit 4a to c determines that the control operation function is invalid, and a command to visually and audibly indicate that the control operation function is invalid from the alerting notification units 6a to 6c. Is output. Further, the control operation invalid time measuring units 7a to 7c operate when the warning notification units 8a to 8c are operated when it is determined that the control operation invalidity continues for a certain time. This warns the surroundings that the cancellation of the invalidation of the control operation may be forgotten, and notifies the elevator centralized management center via the communication line. Therefore, if there is a maintenance worker in the surrounding area, attention is alerted, and even when the maintenance worker is not in the vicinity, the maintenance work is always managed by the elevator centralized management center, so that the release operation by the maintenance worker can be urged.

図２及び図３は、本発明を適用するエレベーター乗り場、及びかご内の概略図であり、周知のように、エレベーター乗り場側のドア１２に隣接して表示器１０及び乗り場呼び登録釦１１が設置される一方、エレベーターかご側のドア１７に隣接して、表示器１３,行先階登録釦１４，ドア開閉釦１５，及び操作盤１６が設置されている。   2 and 3 are schematic views of an elevator hall to which the present invention is applied and a car. As is well known, an indicator 10 and a hall call registration button 11 are installed adjacent to a door 12 on the elevator hall side. On the other hand, a display 13, a destination floor registration button 14, a door opening / closing button 15, and an operation panel 16 are installed adjacent to the elevator car side door 17.

この操作盤１６は、保守作業員等にのみ操作を可能にするため、専用の鍵で設けている。そこで、本実施例の特徴をなす前記管制運転機能の無効スイッチは、この操作盤１６の中にも設置し、エレベーターごとに管制運転機能を無効に設定できるようにしても良い。   The operation panel 16 is provided with a dedicated key so as to be operated only by a maintenance worker or the like. Therefore, the control operation function invalid switch that characterizes the present embodiment may be installed in the operation panel 16 so that the control operation function can be set invalid for each elevator.

図４は、本発明によるエレベーター制御盤の一概略図である。本発明の構成図である。エレベーター制御盤２０はエレベーター機械室に設置され、表示器２１、ブザー２２、警告報知装置２３、ランプ２４を備える。表示器２１は、「管制運転無効中」である旨を表示させて管制運転を無効にしていることを、視覚的に知らせるものである。ブザー２２は、「管制運転無効中」に、エレベーター機械室又は管理室にブザーを鳴動させて、聴覚的に注意喚起を行なうものである。警告報知装置２３は、管制運転機能を無効に設定した後に無効解除を行なわなかった場合、一定時間経過後に通信線を介してエレベーター集中管理センター２５に報知し、「管制運転無効中」が解除されていないことを知らせるものである。   FIG. 4 is a schematic diagram of an elevator control panel according to the present invention. It is a block diagram of the present invention. The elevator control panel 20 is installed in the elevator machine room and includes a display 21, a buzzer 22, a warning notification device 23, and a lamp 24. The display 21 visually indicates that the control operation is invalidated by displaying that the control operation is invalid. The buzzer 22 makes an audible alert by sounding a buzzer in the elevator machine room or the control room during “control operation invalid”. If the warning notification device 23 does not cancel the invalidation after setting the control operation function to be invalid, the warning notification device 23 notifies the elevator central management center 25 via the communication line after a predetermined time has elapsed, and “control operation invalid” is canceled. It is to inform you that it is not.

エレベーター集中管理センター２５では、一定領域内のエレベーターを一括管理しており、保守作業員とも常時連絡を取れるシステムを構築している。したがって、警告報知装置２３からの知らせを受けて、エレベーター集中管理センター２５から直ちに保守員に「管制運転無効中」或いは「その解除忘れ」のエレベーターがあることを知らせ、確実に解除されるまで管理することができる。   The elevator central management center 25 collectively manages elevators in a certain area, and builds a system that can always contact maintenance personnel. Therefore, in response to the notification from the warning notification device 23, the elevator central management center 25 immediately notifies the maintenance staff that there is an elevator “invalidation of control operation” or “forgetting to release it” and manages it until it is reliably released. can do.

図５は、以上の動作を行うための本発明の一実施例であって、そのための管制運転のフローチャートである。   FIG. 5 is an embodiment of the present invention for performing the above operation, and is a flowchart of the control operation for that.

まず保守装置又は前記操作盤１６内のスイッチにより、特定エレベーターの管制運転機能を無効に設定する(ステップ３１)。これにより設定したエレベーターの管制運転機能は無効状態となり、その旨の注意を喚起する(ステップ３２)。管制運転を無効にしている間に、当該エレベーターの特定の試験を行う一方、無効設定をしていないエレベーターの管制運転試験等を行う（ステップ３３）。   First, the control operation function of the specific elevator is set to be invalid by a maintenance device or a switch in the operation panel 16 (step 31). As a result, the control operation function of the elevator that has been set is disabled, and a notice to that effect is issued (step 32). While the control operation is invalidated, a specific test of the elevator is performed, while the control operation test of the elevator that is not invalidated is performed (step 33).

管制運転試験終了後、保守装置等で無効設定を解除するする（ステップ３４）。管制運転機能を無効に設定して（ステップ３１）から一定時間以内に保守装置で無効設定を解除しなかった場合は(ステップ３５)、解除忘れと判断し、警告報知装置から集中管理センターに無効設定が継続していることを警告報知し(ステップ３６)、集中管理センターから保守員に管制運転の解除忘れがある旨を知らせる（ステップ３７）。   After the completion of the control operation test, the invalid setting is canceled by a maintenance device or the like (step 34). If the maintenance operation device does not release the invalid setting within a certain time after setting the control operation function to be invalid (step 31) (step 35), it is determined that the release is forgotten, and the warning notification device invalidates the central control center. A warning is sent that the setting is continued (step 36), and the maintenance staff notifies the maintenance staff that the control operation has been forgotten to be released (step 37).

このように本実施例によれば、エレベーターごとに管制運転機能を無効にすることが出来、保守員が万が一、そのエレベーターごとの解除を忘れてしまった場合でも、エレベーター集中管理センターでの管理も可能となることから、保守点検作業の便宜に伴う管制運転機能の信頼性を損なうこともない。   As described above, according to the present embodiment, the control operation function can be disabled for each elevator, and even if the maintenance staff forgets to release each elevator, the management at the elevator central management center is also possible. Therefore, the reliability of the control operation function associated with the convenience of maintenance and inspection work is not impaired.
