- This invention relates to a control device for diagnosing a failure of an elevator door switch.
- the elevator is equipped with door switches that detect when the doors (car doors and landing doors) are closed. This door switch has a very high frequency of operation, and if a failure occurs, the operation of the elevator must be stopped. For this reason, in an elevator, it is necessary to make a failure diagnosis of a door switch from normal time and strive for early detection of the failure.
- Patent Documents 1 and 2 listed below are examples of conventional techniques related to elevator failure diagnosis.

- E (> C) of FIG. 7 has shown the distance from the door opening start position of a car door to the operation position of the door switch 27.
- the door switch 17 is moved when the car door moves in the door opening direction by the distance D. Operates (when the door switch 17 is normal), the signal of the door switch 17 to the control panel 19 is switched. Then, the door opening / closing control means 33 stops the door opening operation before the moving distance of the car door after the door opening operation starts reaches C, and starts the door closing operation.
- the self-diagnosis of the door switch 17 can be completed without causing the landing door to open and close. For this reason, during the self-diagnosis of the door switch 17, the person at the landing 1 is not made aware of the operation of the elevator, and the person at the landing 1 is not likely to be mistaken for a malfunction of the elevator.

Abstract
Description
特許文献1には、所定の条件下、エレベーターを通常運転から診断運転に移行させ、位置センサ等、所定の機器の故障診断を行うものが提案されている。
また、特許文献2には、地震発生後にエレベーターを通常運転に復帰させるための診断運転において、ドアの開閉トルクや開閉時間等から故障の検出を行うものが提案されている。
しかし、かご内の消灯やアナウンスの実施だけでは、利用者がかごに乗車すること自体を防止することはできない。このため、従来では、ドアスイッチの故障診断中に利用者が誤ってかごに乗車してしまうと、故障診断の中断を余儀なくされていた。
図1はこの発明の実施の形態1における制御装置を備えたエレベーターの要部を示す側面図、図2はこの発明の実施の形態1における制御装置を備えたエレベーターの要部を示す正面図、図3はエレベータードアの全閉時における図2のA-A矢視を示す図である。
図1乃至図3において、1はビルの各階床に設けられたエレベーター乗場、2はエレベーターの昇降路、3は昇降路2内を昇降するエレベーターのかごである。即ち、図1は、所定の階床の乗場1にかご3が停止した時の状態を横から見た図に、図2は、かご3を乗場1側から見た図に相当する。
ドア装置4の具体的構成について、以下に説明する。
図4はこの発明の実施の形態1におけるエレベーターの制御装置を示す構成図である。図4に示す自己診断装置31は、上記自己診断機能を実現するために制御盤19に備えられたものである。この自己診断装置31には、例えば、かご3の走行制御を行う走行制御手段32と、ドア制御装置18に動作指令を出力してエレベータードアの開閉制御を行う戸開閉制御手段33と、ドアスイッチ17及び27の故障の有無を判定する故障判定手段34と、所定の報知機器の動作制御を行う報知機能制御手段35とが備えられている。以下に、図5及び図6も参照して、自己診断装置31の具体的な動作について説明する。
図5に示すように、自己診断装置31は、先ず、自己診断が可能か否かを判断する(S101)。具体的に、自己診断装置31は、故障診断を前回実施してから所定時間(期間)経過した場合やエレベーターが利用されない夜間である場合等、ドアスイッチ17の故障診断を開始する所定の開始条件が成立することにより、自己診断が可能であると判断する。
なお、故障判定手段34は、エレベータードアを閉める時のドアスイッチ17の動作状態に基づいて、上記故障判定を実施しても良い。
なお、故障判定手段34は、エレベータードアを閉める時のドアスイッチ27の動作状態に基づいて、上記故障判定を実施しても良い。
また、自己診断装置31は、その全ての機能を制御盤19に備えておく必要はなく、一部の機能が、他の装置(例えば、ドア制御装置18)に備えられていても構わない。
図7はこの発明の実施の形態2におけるエレベーターの制御装置の機能を説明するための図である。
図7に示す連結装置28では、かごドア及び乗場ドアの全閉時、各プレート29とローラー30との各間に、僅かな間隙が形成されている。このため、かご3が乗場1に停止して戸開動作が開始されると、一方のプレート29がB方向(戸開方向)に移動してローラー30に接触するまでの間、かごドアのみが戸開動作することとなり、乗場ドアの戸開動作は行われない。
その他の構成及び動作は、実施の形態1と同様である。
図8はこの発明の実施の形態3におけるエレベーターの制御装置の動作を示すフローチャートである。本実施の形態では、故障判定手段34によるドアスイッチ17の故障判定のタイミングを、ドアスイッチ27の動作状態に基づいて判断する場合について説明する。
診断階床への着床後、戸開閉制御手段33によって戸開動作が開始されると(S304)、自己診断装置31は、乗場ドアがドアスイッチ27の動作位置まで移動したか否かを判定する(S305)。なお、乗場ドアがドアスイッチ27の動作位置まで移動すると、ドアスイッチ27がONからOFFに切り替わる。このため、自己診断装置31では、ドアスイッチ27の動作が確認された時点で戸開動作を停止させ、故障判定手段34によるドアスイッチ17の故障判定を実施する(S306)。そして、S306における故障判定が終了すると、自己診断装置31は、戸開閉制御手段33によって戸閉動作を開始し、エレベータードアを全閉させて自己診断動作を終了する(S307)。
その他の構成及び動作は、実施の形態1と同様である。
図9はこの発明の実施の形態4におけるエレベーターの制御装置の動作を示すフローチャートである。本実施の形態では、故障判定手段34によるドアスイッチ17及び27の故障判定のタイミングを、ドアの位置情報に基づいて判断する場合について説明する。なお、ドアの位置情報を取得するため、例えば、エレベーターのかご3に、ドアモータ11の出力軸の回転に応じて情報を出力するモータエンコーダ(図示せず)が設けられている。即ち、自己診断装置31は、このモータエンコーダからの出力情報に基づき、上記判定タイミングを判断する。
以下に、ドアスイッチ17の自己診断を行う際の動作について説明する。
診断階床への着床後、戸開閉制御手段33によって戸開動作が開始されると(S404)、自己診断装置31は、上記モータエンコーダの出力情報からエレベータードアの位置を演算し、エレベータードアが所定の規定位置まで移動したか否かを判定する(S405)。そして、自己診断装置31は、エレベータードアが上記規定位置まで移動した時点で戸開動作を停止させ、故障判定手段34によるドアスイッチ17の故障判定を実施する(S406)。また、S406における故障判定が終了すると、自己診断装置31は、戸開閉制御手段33によって戸閉動作を開始し、エレベータードアを全閉させて自己診断動作を終了する(S407)。
その他の構成及び動作は、実施の形態1と同様である。
図10はこの発明の実施の形態5におけるエレベーターの制御装置の動作を示すフローチャートである。本実施の形態では、故障判定手段34によるドアスイッチ17及び27の故障判定のタイミングを、かごドアが戸開動作を開始してからの経過時間に基づいて判断する場合について説明する。
以下に、ドアスイッチ17の自己診断を行う際の動作について説明する。
診断階床への着床後、戸開閉制御手段33によって戸開動作が開始されると(S504)、自己診断装置31は、かごドアの戸開開始から所定の一定時間が経過したか否かを判定する(S505)。そして、自己診断装置31は、戸開開始から上記一定時間が経過した時点で戸開動作を停止させ、故障判定手段34によるドアスイッチ17の故障判定を実施する(S506)。また、S506における故障判定が終了すると、自己診断装置31は、戸開閉制御手段33によって戸閉動作を開始し、エレベータードアを全閉させて自己診断動作を終了する(S507)。
その他の構成及び動作は、実施の形態1と同様である。
図11はこの発明の実施の形態6におけるエレベーターの制御装置の動作を示すフローチャートである。
エレベーターの乗場1には、かご3の位置を表示するインジケーター、かご3の到着を予報するホールランタン、アナウンス装置といった各種報知機器(図示せず)が設置されている。ドアスイッチ17及び27の自己診断時に上記報知機器が動作すると、乗場1にいる利用者の意識がエレベーターに向いてしまう。このため、本実施の形態において、自己診断装置31は、ドアスイッチ17及び27の自己診断時、上記報知機器の報知機能を一時的に停止させるように制御する。
以下に、ドアスイッチ17の自己診断を行う際の動作について説明する。
S603において降車誘導が行われた後、自己診断装置31は、報知機能制御手段35によって報知機器を消灯及び消音し、その機能を停止させる(S603)。報知機器の機能を停止した後、自己診断装置31は、かご3を診断階床に着床させて戸開動作を開始し、エレベータードアを所定の規定幅まで開放する(S604乃至S606)。なお、S606の判定は、図8のS305や図9の405、図10のS505と同様に行っても良い。
その他の構成及び動作は、実施の形態1と同様である。
