また、この発明に係るエレベータ装置は、かご、記かごの移動に応じて信号を発生する移動検出手段、かごの昇降方向に互いに間隔をおいて昇降路内に配置されている複数の記憶媒体、かごに設けられており、記憶媒体に記憶されている情報を読み取る読取手段、かごの昇降方向に互いに間隔をおいて昇降路内に配置されている複数の被検出体、かごに設けられており、被検出体を検出する位置センサ、及び移動検出手段からの信号を用いてかごの移動量及び位置を検出し、かごの運転状態の異常の有無を監視する安全監視装置を備え、安全監視装置には、記憶媒体の検出位置からそれに隣接する被検出体の検出位置までの距離と、被検出体の位置情報とが記憶されており、安全監視装置は、かごの位置を把握できなくなったとき、記憶媒体と被検出体とを検出する運転を行い、記憶媒体の検出位置から被検出体の検出位置までの距離を移動検出手段からの信号に基づいて測定し、測定された距離を記憶されている情報と比較し、その比較結果と記憶媒体の情報と被検出体の位置情報とを用いてかごの位置を把握する。

実施の形態1.
図1はこの発明の実施の形態1によるエレベータ装置を示す構成図である。図において、昇降路1の上部には、機械室2が設けられている。機械室2には、巻上機3が設けられている。巻上機3は、駆動シーブ、駆動シーブを回転させる巻上機モータ、及び駆動シーブの回転を制動する巻上機ブレーキを有している。
上記のような安全監視を実行するため、安全監視装置8は、上部終端階スイッチ14、下部終端階スイッチ15、及び記憶媒体19の位置を記憶する学習運転を実施する。即ち、安全監視装置8による運転モードには、学習運転モードが含まれている。
ここで、安全監視装置8は、例えば通常運転中に安全監視装置8に対する電力供給が断たれた場合など、かご5の位置を把握できなくなったとき、そのときのかご5の位置情報を記憶する手順を踏むことなく機能を停止する。
次に、任意に配置すると述べた記憶媒体19について、隣接する2つの記憶媒体19間の具体的な間隔について図5を参照して説明する。図5は図1のエレベータ装置における記憶媒体19の間隔を示す説明図である。
X=(0.5×a×t12+V2(T-t1))/2[m]
以内とすることで、復帰までに許容される時間T[min]以内に復帰が完了する。
次に、図6はこの発明の実施の形態2によるエレベータ装置を示す構成図である。実施の形態2では、着床センサ18からの信号が、エレベータ制御装置7ではなく安全監視装置8に入力されている。つまり、着床プレート17を着床センサ18により読み取った情報が安全監視に使用される。その他の構成は、実施の形態1と同様である。
上記のような位置情報の補正を行うため、安全監視装置8は、学習運転において着床プレート17の検出位置も記憶する。図7は図6の安全監視装置8による学習運転の動作を示すフローチャートである。図7におけるステップS701~S706の動作は、図3におけるステップS301~S306の動作と同様である。
次に、実施の形態2の安全監視装置8による復帰運転について説明する。実施の形態1では、基本的に2つの記憶媒体19の間の距離を計測することでかご5の位置を確定した。しかし、記憶媒体19を読み取るタグリーダ20の精度は、着床センサ18に比べると低い。そこで、本実施の形態では、復帰運転において着床センサ18を用い、より高精度でかご5の位置を確定させる。
次に、この発明の実施の形態3について説明する。実施の形態3のエレベータ装置の構成は、実施の形態2と同様である。また、安全監視装置8による学習運転も、実施の形態2と同様である。但し、実施の形態3の安全監視装置8は、復帰運転において、学習運転によって記憶された記憶媒体19の検出位置からそれに隣接する着床プレート17の検出位置までの距離と、検出された記憶媒体19の情報と、検出された着床プレート17の位置情報とを用いてかご5の位置を把握する。
以下、実施の形態3の安全監視装置8による復帰運転について説明する。実施の形態2では、2つの記憶媒体19の間の距離を計測して計測値と学習値との整合を確認した後、着床プレート17の検出位置によってかご5の位置を確定した。これに対して、実施の形態3では、記憶媒体19の検出位置から着床プレート17の検出位置までの距離を計測して計測値と学習値との整合を確認した後、その着床プレート17の検出位置によってかご5の位置を確定する。
また、読取手段は、記憶媒体19の種類に応じて選択されるものであり、タグリーダに限定されない。
さらに、被検出体は着床プレート17に限定されるものではなく、位置センサも着床センサ18に限定されるものではない。例えば、被検出体として、昇降路内の任意の位置に設けられたプレートを用いてもよい。また、磁気式の被検出体を用いてもよい。
さらにまた、安全監視装置の監視対象は、過速度走行に限定されるものではなく、例えば戸開走行の有無を監視してもよい。
また、エレベータ装置全体の機器のレイアウト及びローピング方式等は、図1及び図6の例に限定されるものではない。例えば、この発明は、2:1ローピングのエレベータ装置にも適用できる。また、例えば巻上機の位置及び数等も図1及び図6の例に限定されない。
さらに、この発明は、例えば機械室レスエレベータ、ダブルデッキエレベータ、ワンシャフトマルチカー方式のエレベータ、又は斜行エレベータなど、種々のタイプのエレベータ装置に適用できる。
