以下、本実施形態の動作について説明する。   Hereinafter, the operation of this embodiment will be described.

図２は本実施形態に備えられるエレベータ監視装置の監視装置制御部に含まれる計数手段の計数動作に至るまでの手順を示すフローチャートである。   FIG. 2 is a flowchart showing a procedure up to the counting operation of the counting means included in the monitoring device controller of the elevator monitoring device provided in the present embodiment.

乗りかご２０が乗客を乗せて走行し所定階床に到着して停止した際には、乗客が降りるためにドア２１が開く。本実施形態に備えられるエレベータ監視装置３０の監視装置制御部３２は、ドア２１が開端まで開いたときに作動する開端検出装置２２の作動状態を、エレベータ制御装置１０の送受信部１２を介して送信される信号によって監視し、作動しない場合（図２のステップＳ１でＮＯ）は、再度ステップ１を実施する。   When the car 20 travels with passengers and arrives at a predetermined floor and stops, the door 21 is opened for the passengers to get off. The monitoring device control unit 32 of the elevator monitoring device 30 provided in the present embodiment transmits the operating state of the open end detection device 22 that operates when the door 21 is opened to the open end via the transmission / reception unit 12 of the elevator control device 10. If the operation is not performed (NO in step S1 in FIG. 2), step 1 is performed again.

作動した場合（ステップＳ１でＹＥＳ）は、ドア２１が全開状態にあると判断し、ステップＳ２に進む。   If it is activated (YES in step S1), it is determined that the door 21 is fully open, and the process proceeds to step S2.

ステップＳ２では、乗りかご２０内に、予め定めた以上の乗員が乗り込んでいるかどうか、送受信部１２を介して出力される荷重センサ２５からの信号によって確認し、満たない場合（ステップＳ２でＮＯ）は、処理を終了する。   In step S2, it is confirmed by a signal from the load sensor 25 output via the transmission / reception unit 12 whether or not a predetermined number of passengers are in the car 20 or not (NO in step S2). Ends the process.

荷重センサ２５の出力から、予め定めた以上の乗員が乗り込んでいると判断された場合（ステップＳ２でＹＥＳ）、ステップＳ３に進み、ドア閉指令信号の出力状態を監視し、出力されていない場合（ステップＳ３でＮＯ）、再度ステップＳ３を実施する。ドア閉指令信号が出力された場合（ステップＳ３でＹＥＳ）、ステップＳ４へ進む。   If it is determined from the output of the load sensor 25 that more than a predetermined number of passengers are in the vehicle (YES in step S2), the process proceeds to step S3, where the output state of the door close command signal is monitored and not output. (NO in step S3), step S3 is performed again. If the door close command signal is output (YES in step S3), the process proceeds to step S4.

ステップＳ４では、送受信部１２を介して出力されるドアセンサ２６からの信号によって、ドアセンサ２６の作動状態を監視する。ドアセンサ２６が作動した場合（ステップＳ４でＹＥＳ）、ステップＳ５へ進み、閉端検出装置２３の作動状態を監視する。ステップＳ５で閉端検出装置２３が作動していないと判別されたとき（ステップＳ５でＮＯ）、ステップＳ４に戻る。すなわち、ドア２１が閉じきるまで監視が続けられる。閉端検出装置２３が作動した場合（ステップＳ５でＹＥＳ）、処理を終了する。   In step S <b> 4, the operating state of the door sensor 26 is monitored by a signal from the door sensor 26 output via the transmission / reception unit 12. When the door sensor 26 is activated (YES in step S4), the process proceeds to step S5, and the operating state of the closed end detection device 23 is monitored. When it is determined in step S5 that the closed end detection device 23 is not operating (NO in step S5), the process returns to step S4. That is, monitoring is continued until the door 21 is completely closed. If the closed end detection device 23 is activated (YES in step S5), the process is terminated.

ステップＳ６では、この監視装置制御部３２に含まれる開釦操作検出手段によって開釦２４の作動状態が監視される。開釦２４が作動した場合（ステップＳ６でＹＥＳ）には処理を終了する。作動しない場合（ステップＳ６でＮＯ）にはステップＳ７へ進む。   In step S6, the operating state of the open button 24 is monitored by the open button operation detecting means included in the monitoring device control unit 32. If the open button 24 is activated (YES in step S6), the process is terminated. If not activated (NO in step S6), the process proceeds to step S7.

ステップＳ７では、閉端検出装置２３の作動状態を監視し、作動しない場合（ステップＳ７でＮＯ）には、ステップＳ６に戻る。すなわち、ドア２１が閉じきるまで監視が続けられる。ステップＳ７で閉端検出装置２３が作動した場合（ステップＳ７でＹＥＳ）、ステップＳ８へ進む。   In step S7, the operating state of the closed end detection device 23 is monitored, and if it does not operate (NO in step S7), the process returns to step S6. That is, monitoring is continued until the door 21 is completely closed. If the closed end detection device 23 is activated in step S7 (YES in step S7), the process proceeds to step S8.

ステップＳ８では、開釦作動不全カウンタをカウントアップして、この結果を記憶部３１へ記憶させることが行われる。すなわち、監視装置制御部３２に含まれ、開釦作動不全カウンタを構成する前述の計数手段によって計数された設定期間、例えば１ヶ月間の開釦２４の作動不全となった回数が、記憶部３１に記憶される。   In step S8, the open button operation failure counter is counted up and the result is stored in the storage unit 31. That is, the number of times that the open button 24 has become inoperative for a set period, for example, one month, included in the monitoring device control unit 32 and counted by the above-described counting means constituting the open button inoperative counter is stored in the storage unit 31. Is remembered.

図３は、本実施形態に備えられるエレベータ監視装置の監視装置制御部に含まれる計数値比較手段及び判定手段の動作を示すフローチャートである。   FIG. 3 is a flowchart showing the operations of the count value comparison means and the determination means included in the monitoring device controller of the elevator monitoring device provided in the present embodiment.

例えば月末等の所定の時期に、エレベータ監視装置３０の監視装置制御部３２に含まれる計数値比較手段によって、計数手段で計数された今回の計数値と前回の計数値とが記憶部３１から読み出され、今回の計数値と前回の計数値との差を求める演算が行われる。すなわち図３の手順Ｓ１１に示すように、今月分の開釦不全動作カウンタ値と、先月分の開釦作動不全カウンタ値との差を求める演算が行われる。また、監視装置制御部３２に含まれる判定手段によって、前述した差が所定値以上かどうか判別される。前述した差が所定値に満たないと判別された場合（ステップＳ１１でＮＯ）には、処理を終了する。すなわち、開釦２４は正常であると見なされ、この開釦２４の作動確認は不要となる。   For example, at a predetermined time such as the end of the month, the current count value counted by the counting means and the previous count value are read from the storage unit 31 by the count value comparison means included in the monitoring device control unit 32 of the elevator monitoring device 30. The calculation for obtaining the difference between the current count value and the previous count value is performed. That is, as shown in step S11 of FIG. 3, a calculation is performed to obtain the difference between the open button malfunction counter value for the current month and the open button malfunction counter value for the previous month. In addition, it is determined by the determination means included in the monitoring device control unit 32 whether the above-described difference is equal to or greater than a predetermined value. If it is determined that the above-described difference is less than the predetermined value (NO in step S11), the process ends. That is, the open button 24 is regarded as normal, and it is not necessary to confirm the operation of the open button 24.

前述した差が所定値以上と判別された場合（ステップＳ１１でＹＥＳ）には、この判別手段によって開釦２４が作動不全状態にあると判定される。この判定がなされたとき例えば、ステップＳ１２において、監視装置制御部３２から通信部３４、通信回線５０を介して監視センタ４０に、開釦２４の作動不全が検出された旨が通報される。   If it is determined that the above-described difference is greater than or equal to a predetermined value (YES in step S11), it is determined by this determination means that the open button 24 is in an inoperative state. When this determination is made, for example, in step S12, the monitoring device control unit 32 notifies the monitoring center 40 via the communication unit 34 and the communication line 50 that the malfunction of the open button 24 has been detected.

通報を受信した監視センタ４０のオペレータは、当該エレベータの保守担当者に開釦２４の作動確認を行うように指示を出す。保守担当者は、開釦２４の作動を確認し、必要があれば開釦２４の交換等の作業を行う。   The operator of the monitoring center 40 that has received the notification instructs the maintenance staff of the elevator to confirm the operation of the open button 24. The maintenance staff confirms the operation of the open button 24 and performs work such as replacement of the open button 24 if necessary.

以上のように構成した本実施形態に係る故障診断装置によれば、前述のようにエレベータ監視装置３０の監視装置制御部３２に含まれる計数手段と計数値比較手段と判定手段の動作によって、乗りかご２０内に設けられる開釦２４が作動不全状態であることを検出することができる。すなわち、特別な装置を要することなく、監視装置制御部３２における制御処理によって開釦２４の作動不全状態を安価に検出することができる。   According to the failure diagnosis apparatus according to the present embodiment configured as described above, the operation is performed by the operation of the counting means, the count value comparison means, and the determination means included in the monitoring device control unit 32 of the elevator monitoring device 30 as described above. It can be detected that the open button 24 provided in the car 20 is in an inoperative state. That is, the operation failure state of the open button 24 can be detected at low cost by the control process in the monitoring device control unit 32 without requiring a special device.

なお、前述の実施形態では、エレベータ監視装置３０の監視装置制御部３２に含まれる判定手段で、開釦２４が作動不全状態にあると判定されたときに、監視装置制御部３２から通信部３４を介して監視センタ４０に開釦２４が作動不全状態にあることを通報する構成にしてあるが、本発明は、このように構成することには限られない。例えば、監視センタ４０からの開釦２４の作動不全確認要求信号に応じて、エレベータ監視装置３０の監視装置制御部３２に含まれる計数値比較手段及び判定手段が作動し、その判定結果を通信回線５０を介して監視センタ４０に送信するように構成してもよい。   In the above-described embodiment, when the determination unit included in the monitoring device control unit 32 of the elevator monitoring device 30 determines that the open button 24 is in an inoperable state, the monitoring device control unit 32 communicates with the communication unit 34. However, the present invention is not limited to such a configuration. For example, in response to an operation failure confirmation request signal for the open button 24 from the monitoring center 40, the count value comparison means and the determination means included in the monitoring device control unit 32 of the elevator monitoring device 30 operate, and the determination result is transmitted to the communication line. The information may be transmitted to the monitoring center 40 via 50.
