動作制御部１２は、ドア診断処理部１１３Ａから出力された指示に基づいて、巻上げ機５および乗りかご７の機器の動作制御信号を出力する。   The operation control unit 12 outputs operation control signals for the devices of the hoist 5 and the car 7 based on the instruction output from the door diagnosis processing unit 113A.

〈第１実施形態によるドア診断装置を利用したエレベータシステムの動作〉
次に、本実施形態によるエレベータシステム１Ａの動作について、図３のフローチャートを参照して説明する。本実施形態において、エレベータ２Ａの動作を遠隔で監視するために、エレベータ２Ａで定期的に実行する診断運転の実行スケジュール情報が遠隔監視センタ装置３からエレベータ制御装置１０Ａに送信される。送信された診断運転の実行スケジュール情報は、エレベータ制御装置１０Ａの遠隔診断装置１１Ａの通信部１１１を介してドア診断処理部１１３Ａで受信され保持される。 <Operation of Elevator System Using Door Diagnostic Device According to First Embodiment>
Next, the operation of the elevator system 1A according to the present embodiment will be described with reference to the flowchart in FIG. In the present embodiment, in order to remotely monitor the operation of the elevator 2A, the execution schedule information of the diagnostic operation periodically executed in the elevator 2A is transmitted from the remote monitoring center device 3 to the elevator control device 10A. The transmitted diagnosis operation execution schedule information is received and held by the door diagnosis processing unit 113A via the communication unit 111 of the remote diagnosis device 11A of the elevator control device 10A.

ドア診断処理部１１３Ａで保持した診断運転の実行スケジュール情報に基づいて、ドア診断処理の実行タイミングが到来したと判定されると（Ｓ１の「YES」）、乗りかご７を最下階に移動させて乗場６−１に着床させ、かごドア７１に乗場ドア６１−１を係合させた状態でかごドア７１を戸開閉させる指示が出力される（Ｓ２）。そして、出力された指示に基づいて動作制御部１２により巻上げ機５および乗りかご７のドアモータ７２が駆動され、乗りかご７が乗場６−１に着床してかごドア７１およびこれに係合した乗場ドア６１−１が戸開閉する。   When it is determined that the execution timing of the door diagnosis processing has arrived based on the execution schedule information of the diagnosis operation held by the door diagnosis processing unit 113A (“YES” in S1), the car 7 is moved to the lowest floor. Then, an instruction to open and close the car door 71 with the landing door 61-1 engaged with the car door 71 is output (S2). Then, the door motor 72 of the hoist 5 and the car 7 is driven by the operation control unit 12 based on the output instruction, and the car 7 has landed on the landing 6-1 and engaged with the car door 71. The landing door 61-1 opens and closes.

ここで、乗場６−１でかごドア７１および乗場ドア６１−１が戸開閉した際にドア異常検出部１１２で異常が検出されると（Ｓ３の「YES」）、ドア診断処理部１１３Ａにより、乗りかご７を、かごドア７１がいずれの階の乗場ドア６１とも係合しない位置に移動させ、再度かごドア７１を戸開閉させる指示が出力される（Ｓ４）。かごドア７１がいずれの階の乗場ドアとも係合しない位置は、例えば、連続する２つに階の階間かまたは、昇降路内に予め設定された非常救出口に対応する位置である。非常救出口は、高層ビルなどで、非停止階が所定長以上の距離で連続して存在する昇降路において、非常時に乗りかご内の利用者を救出するために昇降路壁面に設けられる救出口である。   Here, when an abnormality is detected by the door abnormality detection unit 112 when the car door 71 and the landing door 61-1 open and close at the landing 6-1 (“YES” in S3), the door diagnosis processing unit 113A performs The car 7 is moved to a position where the car door 71 is not engaged with the landing door 61 on any floor, and an instruction to open and close the car door 71 again is output (S4). The position where the car door 71 does not engage with the landing door on any of the floors is, for example, a position corresponding to an emergency exit set in advance between two consecutive floors or in a hoistway. Emergency rescue exit is a rescue exit provided on the hoistway wall to rescue users in the car in case of emergency in a hoistway where non-stop floors exist continuously over a predetermined length or more in high-rise buildings etc. It is.

出力された指示に基づいて動作制御部１２により巻上げ機５および乗りかご７のドアモータ７２が駆動され、乗りかご７が、いずれの階の乗場ドア６１とも係合しない位置に移動されてかごドア７１が戸開閉する。   The door motor 72 of the hoisting machine 5 and the car 7 is driven by the operation control unit 12 based on the output instruction, and the car 7 is moved to a position where it does not engage with the landing door 61 on any floor. Opens and closes the door.

ここで、乗場６−１でかごドア７１が戸開閉した際にドア異常検出部１１２で異常が検出されなかった場合には（Ｓ５の「NO」）、ドア診断処理部１１３Ａにより、異常が検出された際に乗りかご７が着床していた階、つまり１階の乗場ドア６１−１に異常があると判定されることで、１階に関するドア診断処理が実行される（Ｓ６）。そして、このときはまだ全階床のドア診断処理が完了していないため（Ｓ７の「NO」）ステップＳ８に移行し、ドア診断処理部１１３Ａにより、乗りかご７を次の診断対象階である２階に移動させて乗場６−２に着床させ、かごドア７１に乗場ドア６１−２を係合させた状態でかごドア７１を戸開閉させる指示が出力される（Ｓ８）。   Here, if no abnormality is detected by the door abnormality detection unit 112 when the car door 71 opens and closes at the landing 6-1 ("NO" in S5), the abnormality is detected by the door diagnosis processing unit 113A. When it is determined that the floor on which the car 7 has landed, that is, the landing door 61-1 on the first floor has an abnormality, the door diagnosis process for the first floor is executed (S6). Then, at this time, since the door diagnosis processing for all floors has not been completed yet ("NO" in S7), the process shifts to step S8, and the door diagnosis processing unit 113A causes the car 7 to be the next floor to be diagnosed. An instruction to open and close the car door 71 with the landing door 61-2 engaged with the car door 71 is output (S8).

そして、出力された指示に基づいて動作制御部１２により巻上げ機５および乗りかご７のドアモータ７２が駆動され、乗りかご７が乗場６−２に着床してかごドア７１およびこれに係合した乗場ドア６１−２が戸開閉する。ステップＳ３〜Ｓ６の処理は、ｎ階におけるドア診断処理が完了するまで繰り返される。その際、ステップＳ３で異常が検出されなかった場合には、ステップＳ４〜Ｓ６の処理は実行されず、ステップＳ７に移行する。また、ステップＳ５で異常が検出された場合には、ドア診断処理部１１３Ａによりかごドア７１に異常があると判定される（Ｓ９）。   The door motor 72 of the hoist 5 and the car 7 is driven by the operation control unit 12 based on the output instruction, and the car 7 has landed on the landing 6-2 and engaged with the car door 71. The landing door 61-2 opens and closes. The processing of steps S3 to S6 is repeated until the door diagnosis processing on the nth floor is completed. At this time, if no abnormality is detected in step S3, the processing in steps S4 to S6 is not performed, and the process proceeds to step S7. If an abnormality is detected in step S5, the door diagnosis processing unit 113A determines that the car door 71 has an abnormality (S9).

ステップＳ７において全階床のドア診断処理が完了したと判定され（Ｓ７の「YES」）、いずれかの階の乗場ドア６１で異常ありと判定されたとき（Ｓ１０の「YES」）、またはステップＳ９においてかごドア７１に異常ありと判定されたときには、ドア診断処理部１１３Ａにおいて該当する異常に関する異常情報が生成されて登録されるとともに、通信部１１１から遠隔監視センタ装置３に送信される（Ｓ１１）。   In step S7, it is determined that the door diagnosis process for all floors has been completed ("YES" in S7), and it is determined that there is an abnormality in the landing door 61 of any floor ("YES" in S10), or When it is determined in S9 that the car door 71 has an abnormality, the door diagnosis processing unit 113A generates and registers the abnormality information relating to the abnormality, and transmits the information from the communication unit 111 to the remote monitoring center device 3 (S11). ).

遠隔監視センタ装置３では、エレベータ２Ａからドア診断処理における異常情報が取得されると、当該異常情報を音声またはテキスト情報で出力し、保守員に報知されてドア診断が終了する。また、ステップＳ１０においていずれの階においても乗場ドア６１で異常ありと判定されなかったときには（Ｓ１０の「NO」）、異常情報は生成されず、ドア診断が終了する。   In the remote monitoring center device 3, when the abnormality information in the door diagnosis processing is acquired from the elevator 2A, the abnormality information is output as voice or text information, notified to the maintenance staff, and the door diagnosis ends. If it is not determined in step S10 that there is an abnormality in the landing door 61 on any floor ("NO" in S10), no abnormality information is generated and the door diagnosis ends.

以上の第１実施形態によれば、エレベータドアで異常が発生した際に、異常の原因がかごドア側にあるか、乗場ドア側にあるかを認識しつつ、異常を自動で検出することができる。   According to the first embodiment described above, when an abnormality occurs in an elevator door, it is possible to automatically detect the abnormality while recognizing whether the cause of the abnormality is on the car door side or on the landing door side. it can.
