この発明は、広域地震等により停止した多数のエレベータを点検、復旧させる場合に適用すると好適なエレベータの地震時対応運転装置に関するものである。   The present invention relates to an elevator response operation apparatus suitable for an earthquake when applied to a case where a large number of elevators stopped by a wide area earthquake or the like are inspected and restored.

広域地震等により多数のエレベータが停止した場合、エレベータの点検、復旧には多大の時間を要する。もし、エレベータが高い階で停止している場合には、保守技術者はビルに到着した後かごが停止している階まで階段を上がる必要がある。またはビル屋上の機械室まで上がる必要がある。
従来、地震感知器が作動すると、かごを最寄階に着床させ、運転休止状態とするエレベータの運転装置において、地震感知器に設けられ、通電によって地震感知器を復帰状態とする復帰コイルと、特定階の乗場に設けられた復帰スイッチと、この復帰スイッチの操作によって、復帰コイルへ電流を供給する通電手段と、復帰スイッチの操作によって、かごを特定階に低速運転で呼び寄せる制御手段とを有するエレベータの運転復帰装置が知られている(例えば、特許文献1参照)。また、建物の振動が所定振動を越えると動作する地震検出装置と、この地震検出装置の動作によってエレベータの管制運転を行う管制運転装置を備えたエレベータの運転装置において、建物の特定階の所定位置に設けた呼戻しスイッチと、この呼戻しスイッチを操作したときかごを低速で特定階へ走行させる呼戻し運転回路を備えたエレベータの運転装置(例えば、特許文献2参照)や、地震感知器の作動に応じて地震管制運転装置により最寄階にて運転休止となったかごを呼戻すエレベータの地震時呼戻し装置において、建物の下層階に設けられ、エレベータの運転回路を保守モードに切り換える操作スイッチと、この操作スイッチの操作に応じて最寄階に停止しているかごを所定階へと低速運転させる制御手段とを備えたエレベータの地震時呼戻し装置(例えば、特許文献3参照)が知られている。
When a large number of elevators are stopped due to a wide-area earthquake or the like, it takes a lot of time to check and restore the elevators. If the elevator is stopped on a higher floor, the maintenance engineer must go up the stairs to the floor where the car is stopped after arriving at the building. Or you need to go up to the machine room on the building roof.
Conventionally, when an earthquake detector is activated, a return coil provided in the earthquake detector in an elevator operating device that puts the car on the nearest floor and puts it into a suspended state, and that returns the earthquake detector to a return state when energized; A return switch provided at the landing on the specific floor, an energizing means for supplying current to the return coil by operating the return switch, and a control means for calling the car to the specific floor at low speed by operating the return switch.

従来のかごを特定階へ低速運転で呼び寄せるエレベータの運転復帰装置等では、復帰スイッチを押すと、地震被害の有無を判断せずに不明のままかご指定された特定階へ呼戻しているので、例えば、制御ケーブル、ロープが引っ掛っている場合には、機器の物損事故が発生する恐れがある。また、保守技術者が現場のビルに到着してから、呼戻しているために、最上階で停止している場合は時間がかかるという問題があった。   In the elevator operation return device that calls the conventional car to the specific floor at low speed, when the return switch is pressed, it is called back to the specific floor designated as the car without knowing whether there is earthquake damage, For example, when a control cable or a rope is caught, there is a risk of equipment damage accidents. In addition, there is a problem that it takes time if the maintenance engineer is stopped on the top floor because the service engineer has called back after arriving at the building on site.

この発明は、上述のような課題を解決するためになされたもので、広域地震等により停止した多数のエレベータを点検、復旧させる場合、地震動が小さいと判断できれば、自動的にエレベータを最下階に呼戻す運転を行って、エレベータかごが最下階で待機していることにより、現場のビルに到着した保守技術者が階段を上がらず直ぐにかご上に搭乗でき、早期に点検、復旧を行うことができるようにしたエレベータの地震時対応運転装置を提供するものである。   The present invention has been made to solve the above-described problems. When a large number of elevators stopped due to a wide-area earthquake or the like are inspected and restored, if the earthquake motion can be judged to be small, the elevator is automatically set to the lowest floor. When the elevator car is waiting on the lowest floor, the maintenance engineer who arrived at the site building can get on the car immediately without going up the stairs, and perform early inspection and recovery. It is an object of the present invention to provide an elevator operation device capable of handling an earthquake.

この発明に係るエレベータの地震時対応運転装置においては、地震のP波を感知するP波センサーと、地震のS波を感知するS波地震感知器と、P波センサー及びS波地震感知器からの信号を取り込むエレベータ制御盤と、エレベータ制御盤に設けられ、S波地震感知器が動作した時エレベータかごを最寄階にて運転休止させる地震時管制運転を行う地震時管制運転手段と、エレベータ制御盤に設けられた地震時自動呼戻しスイッチと、P波センサーの動作時刻とS波地震感知器の動作時刻を計測し、その動作時刻の差が所定値以上になったことを測定して検出する取り込み時間測定手段と、地震時自動呼戻しスイッチがONしており、かつエレベータ安全装置が動作していなければ、S波地震感知器を一旦リセットさせるS波地震感知器リセット手段と、余震や振動の揺れの収まりを待つための所定時間が経過したか否かを判定する経過時間判定手段と、取り込み時間測定手段及び経過時間判定手段が動作した時、エレベータかごを低速で下降運転し、最下階に到達したら停止させる低速下降運転手段とを備え、地震発生時には、エレベータかごを最下階で待機させる自動呼戻し運転を行うようにしたものである。   In the elevator operation apparatus for earthquakes according to the present invention, a P-wave sensor for detecting an earthquake P-wave, an S-wave earthquake detector for detecting an earthquake S-wave, a P-wave sensor and an S-wave earthquake detector are provided. An elevator control panel that captures the signal of the vehicle, an earthquake control operation means that is provided in the elevator control panel and performs an earthquake control operation that causes the elevator car to stop operation at the nearest floor when the S-wave seismic detector operates, and an elevator Measures the automatic call-back switch at the time of earthquake, the operation time of the P-wave sensor and the operation time of the S-wave seismic detector, and measures that the difference between the operation times exceeds a predetermined value. If the capture time measurement means to detect and the automatic recall switch at the time of earthquake are ON and the elevator safety device is not operating, the S-wave earthquake detector is reset to temporarily reset the S-wave earthquake detector. The elevator car, when the elapsed time determining means for determining whether or not a predetermined time for waiting for the aftershock or the vibration to settle has elapsed, and when the intake time measuring means and the elapsed time determining means are operated. The vehicle is provided with low-speed descent operation means that descents at a low speed and stops when it reaches the lowest floor, and performs an automatic call-back operation in which an elevator car waits on the lowest floor when an earthquake occurs.

また、取り込み時間測定手段は、P波センサーの動作時刻とS波地震感知器の動作時刻の差が10秒以上になると、震源から90〜100km以上離れ、大きな物損事故が無いものと判断するものである。   In addition, when the difference between the operation time of the P wave sensor and the operation time of the S wave seismic detector is 10 seconds or more, the capture time measuring means determines that there is no major property damage accident, being 90 to 100 km away from the epicenter. Is.

また、この発明に係るエレベータの保守管理システムにおいては、地震のP波を感知するP波センサーと、地震のS波を感知するS波地震感知器と、P波センサー及びS波地震感知器からの信号を取り込むエレベータ制御盤と、エレベータ制御盤に設けられ、S波地震感知器が動作した時エレベータかごを最寄階にて運転休止させる地震時管制運転を行う地震時管制運転手段と、エレベータ制御盤に設けられた地震時自動呼戻しスイッチと、P波センサーの動作時刻とS波地震感知器の動作時刻を計測し、その動作時刻の差が所定値以上になったことを測定して検出する取り込み時間測定手段と、地震時自動呼戻しスイッチがONしており、かつエレベータ安全装置が動作していなければ、S波地震感知器を一旦リセットさせるS波地震感知器リセット手段と、余震や振動の揺れの収まりを待つための所定時間が経過したか否かを判定する経過時間判定手段と、取り込み時間測定手段及び経過時間判定手段が動作した時、エレベータかごを低速で下降運転し、最下階に到達したら停止させる低速下降運転手段とを備え、地震発生時に、S波地震感知器が動作すると、通信回線を介してエレベータ保守会社受信システムに対し、異常発報を自動通報するとともに、エレベータかごを最下階で待機させる自動呼戻し運転が動作完了したことを通報するようにしたものである。   The elevator maintenance management system according to the present invention includes a P wave sensor for detecting an earthquake P wave, an S wave earthquake sensor for detecting an earthquake S wave, a P wave sensor, and an S wave earthquake detector. An elevator control panel that captures the signal of the vehicle, an earthquake control operation means that is provided in the elevator control panel and performs an earthquake control operation that causes the elevator car to stop operation at the nearest floor when the S-wave seismic detector operates, and an elevator Measures the automatic call-back switch at the time of earthquake, the operation time of the P-wave sensor and the operation time of the S-wave seismic detector, and measures that the difference between the operation times exceeds a predetermined value. S-wave seismic detection that resets S-wave seismic detector once if the capture time measuring means to detect and the automatic recall switch at the time of earthquake are ON and the elevator safety device is not operating When the reset means, the elapsed time judgment means that determines whether or not the predetermined time for waiting for the aftershock or the shaking of vibration has elapsed, the take-up time measurement means and the elapsed time judgment means are operated, the elevator car is slowed down. When the S-wave seismic detector is activated when an earthquake occurs, an alarm is issued to the elevator maintenance company reception system via the communication line. The automatic call-back operation that causes the elevator car to stand by on the lowest floor is notified that the operation has been completed.

この発明によれば、広域地震等により停止した多数のエレベータを点検、復旧させる場合、地震動が小さいと判断できれば、自動的にエレベータを最下階に呼戻す運転を行って、エレベータが最下階で待機していることにより、現場のビルに到着した保守技術者が階段を上がらず直ぐにかご上に搭乗でき、早期に点検、復旧を行うことができる。すなわち、過去のデータより、例えば震源から約70〜100km以上離れている場合は、エレベータの機器に大きな物損が無いと判定し、自動的にかごを最下階まで運転して保守技術者の到着を待機することになるので、点検時間の短縮と保守技術者が階段を上がる労力を低減することができる。   According to the present invention, when inspecting and restoring a large number of elevators stopped by a wide area earthquake or the like, if it can be determined that the earthquake motion is small, the elevator is automatically called back to the lowest floor, and the elevator is moved to the lowest floor. The maintenance engineer who arrived at the building at the site can get on the car immediately without going up the stairs, and can perform inspection and recovery at an early stage. That is, from past data, for example, when it is about 70-100 km or more away from the epicenter, it is determined that there is no significant damage to the elevator equipment, and the car is automatically operated to the lowest floor and the maintenance engineer's Since it will wait for arrival, the inspection time can be shortened and the labor of the maintenance engineer going up the stairs can be reduced.

Embodiment 1 FIG.
FIG. 1 is a system configuration diagram showing an elevator earthquake response operation apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a flowchart for explaining the operation of the elevator earthquake response operation apparatus according to Embodiment 1 of the present invention. It is.

図1において、1は地震のP波を感知するP波センサー、2は地震のS波を感知するS波地震感知器で、特低60Gal、低150Gal、高200Galで動作するが、高は急行ゾーン有りのエレベータのみに付けられる。3はエレベータ制御盤で、P波センサー1及びS波地震感知器2からの信号を取り込んでいる。4はエレベータ制御盤3に設けられた地震時管制運転回路である。地震時管制運転回路4は、S波地震感知器2の特低が動作した場合は、所定時間後自動的にリセットし、エレベータは自動復旧する。またS波地震感知器2の低又は高が動作した場合は、エレベータは最寄階で運転を停止し、通常は保守技術者が到着して点検、復旧作業が完了するまでは休止する。しかし、この発明においては、エレベータ制御盤3に設けられた地震時自動呼戻しスイッチ5がONであれば、S波地震感知器2は一旦リセットされるようになっている。6はエレベータ制御盤3に設けられた呼戻し回路、7は呼戻し回路6に設けられた取り込み時間測定回路で、P波センサー1の動作時刻とS波地震感知器2の動作時刻をそれぞれ計測している。この取り込み時間測定回路7は、地震が発生し、P波センサー1が動作し、S波地震感知器2も動作した場合には、その動作時刻の差を測定し検出する。この時間の差が例えば10秒以上ある場合は、P波(6km/秒)、S波(3.5km/秒)の地震動の速度より、震源からの距離は90km程度あると判断する。ここで、P波の到達時刻は、90km/6km=15秒、S波の到達時刻は、90km/3.5km=25秒であり、P波到達時刻から10秒後にS波が到達することになる。最近の地震状況により、地震の震源からの距離と加速度、震度が公表されている。そして、震源からの距離と加速度との相関関係から、震源から100km離れると50Gal以下になることが判った。また、震源からの距離と震度との相関関係から、震源から50km離れると震度は4以下となり、震源から100km離れると震度は3以下となることが判った。このことから、震源から90〜100kmも離れると、震度は3以下で地表の加速度も50Gal程度になり、大きな物損事故が無いことが判っている。8は経過時間判定回路で、ここでは余震の発生、振動の揺れの収まりを待って、例えば5分経過したことを判定している。9はS波地震感知器リセット回路で、エレベータ制御盤3内の地震時自動呼戻しスイッチ5が入っていると、S波地震感知器2は一旦リセットされる。10は自動呼戻しのための回路接点で、経過時間判定回路8により、余震の発生、振動の揺れの収まりを待って、例えば5分経過した後にONするものである。この際、エレベータが地震時管制運転で運転停止していることを確認し、安全装置も動作していないことを確認する。そして、S波地震地震感知器2を一旦リセットして自動呼戻し運転を行う。11は戸制御回路で、ドアが開かないように戸閉のままとする。12は低速下降運転回路で、エレベータを低速運転で最下階まで運転し、最下階に到達した場合には終点スイッチにより停止させる。これにより、余震発生時も再度震源からの距離を測定して自動呼戻し運転を行う。もし、経過時間待ち、又は低速運転下降中に再度、余震が起こった場合には、P波とS波の時間差を再度測定して呼戻し運転を再実施する。そして、エレベータかごが最下階で待機しているので、現場のビルに到着した保守技術者が階段を上がらず直ぐにかご上に搭乗でき、早期に点検、復旧を行うことができる。なお、かごを停止させる時は、かごの天井が最下階+1階の乗場の床から約60cm程度上方となる所で停止させれば、保守技術者は搭乗し易くなる。   In FIG. 1, 1 is a P-wave sensor that detects earthquake P-waves, and 2 is an S-wave earthquake detector that detects earthquake S-waves, which operates at an extra low 60 Gal, low 150 Gal, and high 200 Gal. Only attached to elevators with zones. Reference numeral 3 denotes an elevator control panel that takes in signals from the P-wave sensor 1 and the S-wave earthquake detector 2. An earthquake control operation circuit 4 is provided in the elevator control panel 3. The seismic control operation circuit 4 automatically resets after a predetermined time when the special wave of the S-wave seismic detector 2 operates, and the elevator automatically recovers. If the low or high of the S wave seismic detector 2 operates, the elevator stops operation at the nearest floor, and normally stops until the maintenance engineer arrives and the inspection and restoration work is completed. However, in the present invention, when the earthquake automatic recall switch 5 provided in the elevator control panel 3 is ON, the S-wave earthquake detector 2 is once reset. 6 is a call back circuit provided in the elevator control panel 3, and 7 is an acquisition time measurement circuit provided in the call back circuit 6. The operation time of the P wave sensor 1 and the operation time of the S wave earthquake detector 2 are measured. is doing. When the earthquake occurs, the P-wave sensor 1 is operated, and the S-wave earthquake detector 2 is also operated, the acquisition time measuring circuit 7 measures and detects the difference in operation time. If this time difference is, for example, 10 seconds or more, it is determined that the distance from the epicenter is about 90 km from the speed of the P wave (6 km / sec) and S wave (3.5 km / sec) earthquake motions. Here, the arrival time of the P wave is 90 km / 6 km = 15 seconds, the arrival time of the S wave is 90 km / 3.5 km = 25 seconds, and the S wave arrives 10 seconds after the arrival time of the P wave. Become. Due to recent earthquake conditions, the distance, acceleration, and seismic intensity from the epicenter of the earthquake have been published. And from the correlation between the distance from the epicenter and the acceleration, it was found that when it was 100 km away from the epicenter, it became 50 Gal or less. The correlation between the distance from the epicenter and the seismic intensity showed that the seismic intensity was 4 or less when 50 km away from the epicenter, and the seismic intensity was 3 or less when 100 km away from the epicenter. From this fact, it is known that when it is 90-100 km away from the epicenter, the seismic intensity is 3 or less and the acceleration of the ground surface is about 50 Gal, so that there is no serious property damage accident. Reference numeral 8 denotes an elapsed time determination circuit, which determines, for example, that five minutes have elapsed after waiting for the occurrence of an aftershock and the vibration to settle. Reference numeral 9 denotes an S wave earthquake detector reset circuit. When the earthquake automatic recall switch 5 in the elevator control panel 3 is turned on, the S wave earthquake detector 2 is once reset. Reference numeral 10 denotes a circuit contact for automatic call-back, which is turned on after elapse of 5 minutes, for example, after an aftershock has occurred and the vibration has settled by the elapsed time determination circuit 8. At this time, it is confirmed that the elevator is stopped due to the control operation during the earthquake, and it is confirmed that the safety device is not operating. Then, the S-wave earthquake / earthquake detector 2 is reset once and the automatic call back operation is performed. Reference numeral 11 denotes a door control circuit which is kept closed so that the door does not open. Reference numeral 12 denotes a low-speed descending operation circuit, which operates the elevator to the lowest floor at a low-speed operation and stops the elevator by the end point switch when reaching the lowest floor. In this way, even aftershocks occur, the distance from the epicenter is measured again and the automatic recall operation is performed. If an aftershock occurs again while waiting for the elapsed time or during low-speed operation descent, the time difference between the P wave and S wave is measured again and the call back operation is performed again. And since the elevator car is waiting on the lowest floor, the maintenance engineer who arrives at the building on the site can get on the car immediately without going up the stairs, and can perform inspection and recovery at an early stage. When the car is stopped, the maintenance engineer can easily board the car if the car ceiling is stopped about 60 cm above the floor of the lowest floor + 1 floor.

次に、エレベータの地震時対応運転装置の動作について、図2により説明する。
地震が発生した時、先ず、ステップS1でエレベータ制御盤3に設けられた地震時自動呼戻しスイッチ5がONであるか否かを確認し、ステップS2でP波信号の有無を確認し、ステップS3でS波信号の有無を確認する。次に、ステップS4でP波信号とS波信号の時間差が例えば10秒以上あるかどうかを取り込み時間測定回路7で測定する。この時間差の測定は、例えば時間差が10秒以上ある場合は、P波(6km/秒)、S波(3.5km/秒)の地震動の速度より、震源からの距離は90km程度あると判断する。すなわち、P波の到達時刻は、90km/6km=15秒、S波の到達時刻は、90km/3.5km=25秒であり、P波到達時刻から10秒後にS波が到達する。そして、最近の地震状況により、地震の震源からの距離と加速度、震度が公表されており、震源からの距離と加速度との相関関係から、震源から100km離れると50Gal以下になることが判っている。また、震源からの距離と震度との相関関係から、震源から50km離れると震度は4以下となり、震源から100km離れると震度は3以下となることが判っている。このような事実から、震源から90〜100kmも離れると、震度は3以下で地表の加速度も50Gal程度になり、大きな物損事故が無いことが判っている。したがって、P波信号とS波信号の時間差が、例えば10秒以上あるかどうかを測定するということには重要な意味があるのである。また、ステップS5ではエレベータのかごの位置が最下階にあるかどうかを確認する。そして、エレベータの安全装置が動作していなければ(ステップS6)、S波地震感知器リセット回路9によりS波地震感知器2は一旦リセットされる(ステップS7)。次に、ステップS8では経過時間判定回路8により、S波信号を感知してから例えば5分経過したか否かを判定する。そして、ステップS9でS波信号が無ければ、ステップS10に進み、エレベータを低速で最下階まで下降運転を行う。最下階に到達した場合には(ステップS11)、終点スイッチにより停止させ、エレベータは運転を休止する(ステップS12)。また、ステップS9で余震が発生し、S波信号を感知した時は、ステップS2に戻り再度震源からの距離を測定する。また、ステップS11で低速運転下降中に再度、余震が起こった場合には、P波とS波の時間差を再度測定して呼戻し運転を再実施する。これにより、エレベータかごが最下階で待機しているので、現場のビルに到着した保守技術者が階段を上がらず直ぐにかご上に搭乗でき、早期に点検、復旧を行うことができる。なお、かごを停止させる時は、かごの天井が最下階+1階の乗場の床から約60cm程度上方となる所で停止させれば、保守技術者は搭乗し易くなる。
Next, the operation of the elevator earthquake response operation device will be described with reference to FIG.
When an earthquake occurs, first, in step S1, it is confirmed whether or not the earthquake automatic call back switch 5 provided in the elevator control panel 3 is ON. In step S2, the presence or absence of a P wave signal is confirmed. In S3, the presence or absence of an S wave signal is confirmed. Next, in step S4, whether the time difference between the P wave signal and the S wave signal is 10 seconds or more is measured by the acquisition time measuring circuit 7. This time difference is measured, for example, when the time difference is 10 seconds or more, the distance from the epicenter is determined to be about 90 km from the speed of the P wave (6 km / second) and S wave (3.5 km / second) ground motion. . That is, the arrival time of the P wave is 90 km / 6 km = 15 seconds, the arrival time of the S wave is 90 km / 3.5 km = 25 seconds, and the S wave arrives 10 seconds after the arrival time of the P wave. And according to the recent earthquake situation, the distance, acceleration, and seismic intensity from the epicenter of the earthquake have been announced, and it is known from the correlation between the distance from the epicenter and the acceleration that it becomes 50 Gal or less when 100 km away from the epicenter. . The correlation between the distance from the epicenter and the seismic intensity indicates that the seismic intensity is 4 or less when 50 km away from the epicenter, and the seismic intensity is 3 or less when 100 km away from the epicenter. From these facts, it is known that when it is 90 to 100 km away from the epicenter, the seismic intensity is 3 or less and the acceleration of the ground surface is about 50 Gal, and there is no major property damage accident. Therefore, it is important to measure whether the time difference between the P wave signal and the S wave signal is 10 seconds or more, for example. In step S5, it is confirmed whether the elevator car is on the lowest floor. If the elevator safety device is not operating (step S6), the S-wave earthquake detector 2 is once reset by the S-wave earthquake detector reset circuit 9 (step S7). Next, in step S8, the elapsed time determination circuit 8 determines whether, for example, 5 minutes have elapsed since the S wave signal was sensed. And if there is no S wave signal at step S9, it will progress to step S10 and will perform a descent | fall operation to the lowest floor at a low speed. When it reaches the lowest floor (step S11), it is stopped by the end point switch, and the elevator stops its operation (step S12). When an aftershock occurs in step S9 and an S wave signal is detected, the process returns to step S2 and again measures the distance from the epicenter. If an aftershock occurs again during the low-speed operation descent in step S11, the time difference between the P wave and the S wave is measured again and the recall operation is performed again. Thereby, since the elevator car is waiting on the lowest floor, a maintenance engineer who arrives at the building on the site can get on the car immediately without going up the stairs, and can perform inspection and recovery at an early stage. When the car is stopped, the maintenance engineer can easily board the car if the car ceiling is stopped about 60 cm above the floor of the lowest floor + 1 floor.
