Description

本発明は、地震発生時における乗客に対する安全対策が施されたエレベータの地震監視制御装置に関する。   The present invention relates to a seismic monitoring and control apparatus for an elevator that is provided with safety measures for passengers when an earthquake occurs.

近年、建設される大規模なビルや建屋に組込まれたエレベータにおいては、地震発生時にエレベータのかご内への乗客の閉じ込め事故防止や機器損傷防止のために、エレベータの昇降路のピット内や機械室内に地震検出器が据付られている。そして、このエレベータの機械室内に巻上機と共に設置された制御盤内には、エレベータの通常時に呼び登録装置から入力された呼びの指定する階へかごを移動するエレベータ通常運転部の他に、地震発生時に、エレベータ通常運転部の運転動作を中止させて、地震発生時に階と階との間に位置しているかごを最寄階へ移動させ、この最寄階で戸開して地震発生時にこのかごに乗合わせた乗客を当該最寄階のエレベータホールへ強制的に退避させる管制運転を実行する管制運転部が組込まれている。   In recent years, elevators built in large-scale buildings and buildings have been constructed in pits and machinery of elevator hoistways to prevent passengers from being trapped in elevator cars and equipment damage in the event of an earthquake. An earthquake detector is installed in the room. In addition, in the control panel installed with the hoisting machine in the elevator machine room, in addition to the elevator normal operation unit that moves the car to the floor designated by the call input from the call registration device at the normal time of the elevator, When an earthquake occurs, stop the elevator normal operation, move the car located between the floors to the nearest floor at the time of the earthquake, open the door on this nearest floor and generate an earthquake At times, a control operation unit is installed that performs a control operation for forcibly evacuating passengers who have boarded the car to the elevator hall on the nearest floor.

地震発生時においては、周知のように、最初に縦波からなる初期微動と称されるP波(Primary Wave)が到着し、続いて横波からなる本震と称されるS波(Secondary Wave)が到着する。エレベータにおいては、揺れの大きいS波が到着する前の揺れの少ないP波を専用のP波検出器で検出して、前述した管制運転を実施して、乗客の安全を確保する。したがって、このP波検出器の検出感度は例えば80ガルの高感度に設定されている。   When an earthquake occurs, as is well known, a P wave (Primary Wave) called initial tremor consisting of longitudinal waves arrives first, followed by an S wave (Secondary Wave) called main shock consisting of transverse waves. arrive. In an elevator, a P wave with less shaking before the arrival of a large S wave is detected by a dedicated P wave detector, and the above-described control operation is performed to ensure passenger safety. Therefore, the detection sensitivity of this P wave detector is set to a high sensitivity of, for example, 80 gal.

この乗客の安全を確保するために用いるP波検出器の他に、発生した地震の本当の強度を検出して機器の損傷を予測するためのS波検出器が組込まれている。したがって、このS波検出器の検出感度は例えば150ガルの低感度に設定されている。そして、検出感度が150ガルの低感度に設定されたS波検出器がS波を検出すると、150ガル以上の強い振動レベルのため、機器損傷の可能性を考慮し、無条件でエレベータを運転中止させる。そして、この場合、当該エレベータの保守管理会社の保守員が当該エレベータの設置場所を訪れて、当該エレベータに対する点検を実施した後に、保守員がマニュアル操作でエレベータの運転を再開させる。   In addition to the P-wave detector used to ensure the safety of passengers, an S-wave detector is incorporated for detecting the true intensity of an earthquake that has occurred and predicting damage to the equipment. Therefore, the detection sensitivity of this S wave detector is set to a low sensitivity of 150 gal, for example. When the S-wave detector with a detection sensitivity set to a low sensitivity of 150 gal detects an S-wave, the vibration level is more than 150 gal. Stop it. In this case, after a maintenance worker of the elevator maintenance management company visits the installation location of the elevator and inspects the elevator, the maintenance worker restarts the operation of the elevator manually.

一方、80ガルの高感度に設定されているP波検出器がP波を検出して、150ガルの低感度に設定されているS波検出器がS波を検出しない場合は、地震の揺れは小さくて、エレベータの運転に支障は無いと考えられるため、地震発生後、一定時間後にエレベータの通常運転を自動的に再開する。   On the other hand, if the P wave detector set to a high sensitivity of 80 gal detects a P wave and the S wave detector set to a low sensitivity of 150 gal does not detect an S wave, the earthquake shakes Is small, and it is considered that there is no hindrance to the operation of the elevator. Therefore, after the occurrence of the earthquake, the normal operation of the elevator is automatically resumed after a certain time.

このような地震監視制御機能が付されたエレベータの運転状況は、このエレベータの設置位置に対して離れた位置に設置された監視センターに、例えば公衆電話網等の通信回線を介して自動的に送信される。多数のエレベータの運転状況が入力される監視センターのオペレータは、各エレベータから受信した地震の状況に基づいて、保守員を各エレベータに点検作業に向かわす。   The operation status of an elevator with such an earthquake monitoring control function is automatically transmitted to a monitoring center installed at a position distant from the installation position of the elevator via a communication line such as a public telephone network. Sent. The operator of the monitoring center to which a large number of elevator operation statuses are input sends maintenance personnel to each elevator for inspection work based on the earthquake status received from each elevator.

この場合、監視センターは、一つの都市や地域等の一定範囲に存在する多数のエレベータから運転状況が入力されるので、地震発生時には、この地域の全てのエレベータから一斉に地震発生の状態が監視センターへ送信されるので、各エレベータと監視センターとを接続する通信回線が混んで、輻輳が生じる懸念がある。   In this case, the monitoring center inputs the operation status from a large number of elevators that exist in a certain area such as one city or region, so when an earthquake occurs, the status of the earthquake occurrence is monitored from all the elevators in this region all at once. Since it is transmitted to the center, there is a concern that the communication line connecting each elevator and the monitoring center is congested, resulting in congestion.

そこで、特許文献1の「エレベータの遠隔監視装置」においては、各エレベータ毎に、地震検出時刻から地震検出情報を監視(保守)センターへ送信する送信時刻までの経過時間をずらせている。その結果、各エレベータと監視センターとを接続する通信回線が混んで、輻輳が生じることが未然に防止できる。
特開平3―106776号公報
Therefore, in the “elevator remote monitoring device” of Patent Document 1, the elapsed time from the earthquake detection time to the transmission time for transmitting the earthquake detection information to the monitoring (maintenance) center is shifted for each elevator. As a result, it is possible to prevent congestion from occurring due to congestion of communication lines connecting each elevator and the monitoring center.
Japanese Patent Laid-Open No. 3-106776

しかしながら、上述した特許文献1に記載された技術手法においても、まだ改良すべき次のような課題があった。   However, the technical method described in Patent Document 1 described above still has the following problems to be improved.

すなわち、前述したように、P波検出器とS波検出器との2台の地震波検出器でそれぞれ、P波、S波を個別に検出してエレベータの各部を制御するシステムにおいては、前述したように、地震発生時に各エレベータが監視センターへ通知する情報としては、P波検出器がP波を検出したこと、管制運転時においてかごが最寄階へ到着したこと、S波検出器がS波を検出したこと、その結果エレベータを運転中止したこと、所定の猶予時間を過ぎてもかごが最寄階へ到着しないこと、P波を検出し一定時間経過してもS波が検出されずにエレベータの運転を再開したこと等である。   That is, as described above, in the system in which the P wave detector and the S wave detector respectively detect the P wave and the S wave and control each part of the elevator, As described above, when an earthquake occurs, each elevator notifies the monitoring center that the P wave detector has detected a P wave, that the car has arrived at the nearest floor during control operation, and that the S wave detector has S Detecting the wave, as a result of stopping the elevator, the car not arriving at the nearest floor even after a predetermined grace period, S wave is not detected even if the P wave is detected and a certain time has passed The elevator operation was resumed.

以上のように、1つのエレベータが監視センターへ送信する情報と、送信タイミングとはそれぞれ重要な意味を持つ。したがって、各情報の送信タイミングを情報種別でなくエレベータ毎に単純にタイミングをずらせることは、監視センターにとっては、重要な情報が欠落したり、後回しになることになる。   As described above, the information transmitted by one elevator to the monitoring center and the transmission timing are important. Therefore, simply shifting the transmission timing of each information for each elevator, not for the information type, may cause important information to be lost or delayed for the monitoring center.

例えば、かご内への乗客の閉じ込め事故の可能性のある「所定の猶予時間を過ぎてもかごが最寄階へ到着しないこと」等の重要な情報はその情報が発生した時点で直ちに監視センターへ通知すべきである。   For example, important information such as “the car does not arrive at the nearest floor after a certain grace period”, which may cause a passenger confinement accident in the car, is immediately monitored at the time the information occurs. Should be notified.

本発明はこのような事情に鑑みてなされたものであり、地震発生時にエレベータから監視センターへ通知すべき情報とこの情報の通知タイミングを最適に設定することによって、たとえ地震発生時においても各エレベータから監視センターへの通信回線の輻輳や監視センターでの情報処理量の増大化を抑制したうえで、監視センターは各エレベータにおけける必要不可欠な情報のみを、それぞれ最適タイミングで監視できるエレベータの地震監視制御装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and by setting the information to be notified from the elevator to the monitoring center when an earthquake occurs and the notification timing of this information, each elevator can be set even in the event of an earthquake. Elevator earthquakes that can monitor only the essential information in each elevator at the optimal timing after suppressing congestion of communication lines from the monitoring center to the monitoring center and an increase in the amount of information processing at the monitoring center. An object is to provide a monitoring and control apparatus.

上記課題を解消するために、本発明においては、通常時に呼びが指定する階へかごを移動するエレベータ通常運転を実施し、P波検出器が初期微動規定レベル以上のP波を検出するとエレベータ通常運転を中止して地震発生時の管制運転を実施し、P波検出に続いてS波検出器が本震規定レベル以上のS波を検出するとエレベータ通常運転の中止を維持し、P波検出から一定時間以内にS波検出器がS波を検出しない場合はエレベータ通常運転を自動的に再開するエレベータの地震監視制御装置において、
P波検出の情報はエレベータ通常運転の再開時に監視センターへ通知し、S波検出の情報は当該S波が検出された時点で監視センターへ通知する。
In order to solve the above-mentioned problems, in the present invention, when an elevator normal operation of moving a car to a floor designated by a call at normal times is carried out and the P wave detector detects a P wave exceeding the initial fine movement regulation level, Stop operation and carry out control operation at the time of earthquake occurrence. If the S wave detector detects an S wave above the specified level of the main shock following the detection of the P wave, the normal operation of the elevator will be stopped and constant from the P wave detection. In the elevator seismic monitoring and control device that automatically resumes the elevator normal operation when the S wave detector does not detect the S wave within the time,
Information of P wave detection is notified to the monitoring center when the elevator normal operation is resumed, and information of S wave detection is notified to the monitoring center when the S wave is detected.

このような構成のエレベータの地震監視制御装置においては、地震の初期微動であるP波を検出した時点では監視センターへの通報は行わずに、P波の次に来るS波のレベルが本震規定レベルより小さい場合は一定時間後にエレベータが通常運転を再開したことを監視センターへ通知する。一方、S波のレベルが本震規定レベルより大きい場合は、S波検出の情報は即座に監視センターへ通知される。   In the elevator seismic monitoring and control apparatus having such a configuration, when the P wave, which is the initial tremor of the earthquake, is detected, the monitoring center is not notified and the level of the S wave that follows the P wave is determined to be the main shock regulation. If it is less than the level, the monitoring center is notified that the elevator has resumed normal operation after a certain time. On the other hand, if the S wave level is higher than the main shock regulation level, the S wave detection information is immediately notified to the monitoring center.

また、別の発明においては、管制運転は、P波検出時に階と階との間に位置していたかごを最寄階へ移動し、当該最寄階で戸開する最寄階移動手段を含む。そして、P波検出から所定の猶予時間内に、当該かごが最寄階に到達しない場合は、最寄階不到着の情報を監視センターへ通知する。   In another aspect of the invention, the control operation includes a nearest floor moving means for moving a car located between the floors when the P wave is detected to the nearest floor and opening the door on the nearest floor. Including. If the car does not reach the nearest floor within a predetermined grace period from the P-wave detection, the monitoring center is notified of information on the arrival of the nearest floor.

さらに、別の発明においては、P波検出から一定時間以内に、S波検出器がS波を検出してなくて、かつかごが最寄階に到着している場合に、エレベータ通常運転を自動的に再開するようにしている。このように、かごの正常運転が確認されたのち、エレベータは通常運転に復旧する。   Furthermore, in another invention, the normal operation of the elevator is automatically performed when the S wave detector does not detect the S wave and the car has arrived at the nearest floor within a certain time from the P wave detection. To resume. Thus, after the normal operation of the car is confirmed, the elevator is restored to the normal operation.

本発明においては、たとえ地震発生時においても各エレベータから監視センターへの通信回線の輻輳や監視センターでの情報処理量の増大化を抑制したうえで、監視センターは各エレベータにおける必要不可欠な情報のみを、それぞれ最適タイミングで監視できる。   In the present invention, even when an earthquake occurs, the monitoring center can suppress only the communication information from each elevator to the monitoring center and increase the amount of information processing at the monitoring center. Can be monitored at the optimum timing.

以下、本発明の一実施形態を図面を用いて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図1は本発明の一実施形態に係わる地震監視制御装置が組込まれたエレベータの概略構成図である。   FIG. 1 is a schematic configuration diagram of an elevator in which an earthquake monitoring control apparatus according to an embodiment of the present invention is incorporated.

建屋内に設けられた昇降路1の上側の機械室2内に巻上機3、図示しない例えばコンピュータ等の情報処理装置が組込まれている制御盤が設けられている。巻上機3に掛けられたメインロープ4の一方端にかご5が吊り下げられ、他方端に釣り合い錘6が吊り下げられている。かご5内にはかご呼登録装置7が設けられ、建屋の各階のエレベータホールには乗場呼び登録装置8が取付られている。制御盤内に組込まれているエレベータ通常運転部9は、かご呼登録装置7及び各乗場呼び登録装置8で登録された呼びに基づいて、外部電源10から電力が供給されている駆動部11を介して巻上機3を回転駆動することによって、かご5を昇降路1内で前記呼びが指定する目的階へ移動制御する。   In a machine room 2 above the hoistway 1 provided in the building, a hoisting machine 3 and a control panel in which an information processing device such as a computer (not shown) is incorporated are provided. A car 5 is suspended from one end of the main rope 4 hung on the hoisting machine 3, and a counterweight 6 is suspended from the other end. A car call registration device 7 is provided in the car 5, and a hall call registration device 8 is attached to an elevator hall on each floor of the building. The elevator normal operation unit 9 incorporated in the control panel has a drive unit 11 to which electric power is supplied from the external power source 10 based on calls registered in the car call registration device 7 and each hall call registration device 8. The car 5 is controlled to move to the destination floor specified by the call in the hoistway 1 by rotating the hoisting machine 3 through the hoistway 1.

さらに、昇降路1の最下階の下側に設けられたピット12内にはP波検出器13が設置されている。このP波検出器13は地震における予め定められた例えば80ガルの初期微動規定レベル以上のP波(Primary Wave)を検出すると、P波検出信号aを制御盤内に設けられた管制運転部14、タイマ回路15へ送出する。   Further, a P wave detector 13 is installed in a pit 12 provided below the lowermost floor of the hoistway 1. When this P-wave detector 13 detects a P-wave (Primary Wave) that is equal to or higher than an initial fine movement regulation level of, for example, 80 gal in an earthquake, a control operation unit 14 provided with a P-wave detection signal a in the control panel. To the timer circuit 15.

また、機械室2内にはS波検出器16が設置されている。このS波検出器16は地震における予め定められた例えば150ガル等の本震規定レベル以上のS(Secondary Wave)波を検出すると、S波検出信号bを制御盤内に設けられたエレベータ運転中止部17及びエレベータ運転再開部21へ送出する。   An S wave detector 16 is installed in the machine room 2. When this S wave detector 16 detects an S (Secondary Wave) wave that exceeds a predetermined level of a main shock such as 150 gal in an earthquake, for example, an elevator operation stop unit provided in the control panel with an S wave detection signal b. 17 and the elevator operation restarting unit 21.

管制運転部14内には最寄階移動部18が組込まれている。そして、この管制運転部14は、P波検出器13からP波検出信号aが入力されると、エレベータ通常運転部9へ通常運転の中止を指示して、駆動部11を介して、地震発生時の管制運転cを開始する。具体的には、最寄階移動部18が起動して、地震発生時点で運転中のかご5の現在位置を駆動部11を介して検出し、この現在位置から最も短時間で、又は最も短距離で行くことができる最寄り階を求める。そして、駆動部11へかご5を強制的に最寄階へ移動させる指示を送ると共に、最寄階到着検出部19を起動する。   A nearest floor moving unit 18 is incorporated in the control operation unit 14. Then, when the P-wave detection signal a is input from the P-wave detector 13, the control operation unit 14 instructs the elevator normal operation unit 9 to stop normal operation, and an earthquake occurs via the drive unit 11. Control operation c at the time is started. Specifically, the nearest floor moving unit 18 is activated to detect the current position of the car 5 that is in operation at the time of the occurrence of the earthquake through the driving unit 11, and from the current position, the shortest time or the shortest time is detected. Find the nearest floor that can be reached by distance. Then, an instruction to forcibly move the car 5 to the nearest floor is sent to the drive unit 11 and the nearest floor arrival detection unit 19 is activated.

最寄階到着検出部19は、かご5と各階のドア近傍とに設けられた各係合部材20a、20bが互いに係合することで、かご5が最寄階に到着したことを確認し、最寄階到着情報dを管制運転部14へ送出すると共に、エレベータ運転再開部21及び最寄階不到着判定部22へ送出する。   The nearest floor arrival detection unit 19 confirms that the car 5 has arrived at the nearest floor by engaging each of the engaging members 20a and 20b provided in the vicinity of the car 5 and the door of each floor, The nearest floor arrival information d is sent to the control operation unit 14 and also sent to the elevator operation resuming unit 21 and the nearest floor non-arrival determining unit 22.

最寄階到着検出部19から最寄階到着情報dを受領した管制運転部14は、当該最寄階において、かご5のドアを開き、乗客を該当階のエレベータホールへ退避させる。   The control operation unit 14 that has received the nearest floor arrival information d from the nearest floor arrival detection unit 19 opens the door of the car 5 on the nearest floor and retracts the passenger to the elevator hall on the corresponding floor.

また、タイマ回路15は、P波検出器13からP波検出信号aが出力された時刻からの経過時間tを計時し、計時した経過時間tをエレベータ運転再開部21及び最寄階不到着判定部22へ送出する。   The timer circuit 15 measures the elapsed time t from the time when the P wave detection signal a is output from the P wave detector 13, and determines the elapsed time t measured by the elevator operation resuming unit 21 and the nearest floor non-arrival determination. Send to unit 22.

通信部23は、このエレベータの運転状態を例えば公衆電話回線網等の通信回線24を介してエレベータの保守管理会社の監視センター25に送信する。   The communication unit 23 transmits the operation state of the elevator to a monitoring center 25 of an elevator maintenance management company via a communication line 24 such as a public telephone network.

次に、エレベータ通常運転部9、管制運転部14、エレベータ運転中止部17、最寄階不到着判定部22、及びエレベータ運転再開部21の動作を図2、図3、図4、図5のタイムチャートを用いて説明する。   Next, the operations of the elevator normal operation section 9, the control operation section 14, the elevator operation stop section 17, the nearest floor non-arrival determination section 22, and the elevator operation resumption section 21 are as shown in FIG. 2, FIG. 3, FIG. This will be described using a time chart.

図2に示すように、P波検出器13のP波検出信号aが出力された経過時間t=0にて、管制運転部14は、エレベータ通常運転部9のエレベータ通常運転eを中止し、自己の管制運転cを開始する。そして、P波検出信号aが出力された4〜5秒の経過時間t1にて、エレベータ運転中止部17が「S波検出、地震発生、エレベータ運転中止」の情報fを通信部23、通信回線24を介して監視センター25へ送信する。 As shown in FIG. 2, at the elapsed time t = 0 when the P wave detection signal a of the P wave detector 13 is output, the control operation unit 14 stops the elevator normal operation e of the elevator normal operation unit 9, Start own control operation c. Then, at the elapsed time t 1 of 4 to 5 seconds when the P wave detection signal a is output, the elevator operation stopping unit 17 sends the information “S wave detection, earthquake occurrence, elevator operation stop” information f to the communication unit 23. The data is transmitted to the monitoring center 25 via the line 24.

また、経過時間t2にて、管制運転cが終了して、最寄階到着検出部19から最寄階到着情報dが出力されると、かご5の最寄階移動が正常に終了したことになる。その結果、P波検出時刻(t=0)から例えば5分等の一定時間TSを経過した時点において、最寄階到着情報dが出力された状態であるので、最寄階不到着判定部23は、監視センター25へなにも送信しない。 In addition, when the control operation c ends at the elapsed time t 2 and the nearest floor arrival information d is output from the nearest floor arrival detection unit 19, the movement of the nearest floor of the car 5 has been completed normally. become. As a result, since the nearest floor arrival information d has been output when a certain time T S such as 5 minutes elapses from the P wave detection time (t = 0), the nearest floor non-arrival determination unit 23 does not transmit anything to the monitoring center 25.

さらに、P波検出時刻(t=0)から例えば3分等の一定時間TAを経過した時点において、S波検出信号bは出力済であるので、エレベータ運転再開部21は、監視センター25へなにも送信しない。 Furthermore, since the S wave detection signal b has already been output when a certain time T A such as 3 minutes has elapsed from the P wave detection time (t = 0), the elevator operation resuming unit 21 moves to the monitoring center 25. Do not send anything.

したがって、P波が検出され、P波検出後、一定時間TA内にS波が検出され、さらにP波検出後、一定時間TB内にかごが最寄階に到着している条件においては、監視センター25に対して、S波検出タイミングで「S波検出、地震発生、エレベータ運転中止」の情報fが1回のみ送信される。 Therefore, the detected P-wave, after P-wave detection, S-wave is detected within a predetermined time T A, after further P-wave detection, the condition where the car for a predetermined time T in B has arrived to the nearest floor is The information f “S wave detection, earthquake occurrence, elevator operation stop” is transmitted to the monitoring center 25 only once at the S wave detection timing.

また、図3に示すように、地震の規模が大きくて、管制運転部14がP波検出(t=0)に同期して、管制運転cを開始したが、機器に損傷が生じて、かご5が最寄階に到着しない場合は、最寄階到着検出部19から最寄階到着情報dが出力されことはない。その結果、P波検出時刻(t=0)から5分等の一定時間TBを経過した時点において、最寄階到着情報dは出力されない状態であるので、最寄階不到着判定部23は、監視センター25へ「かご、最寄階不到着」の情報fを送信する。 In addition, as shown in FIG. 3, the magnitude of the earthquake was so large that the control operation unit 14 started the control operation c in synchronization with the P wave detection (t = 0). When 5 does not arrive at the nearest floor, the nearest floor arrival information d is not output from the nearest floor arrival detection unit 19. As a result, at the time has elapsed for a predetermined time T B of 5 minutes or the like from the P-wave detection time (t = 0), since the nearest floor arrival information d is in a state of not outputted, nearest floor not arrive determination section 23 , Information f “cage, non-arrival at the nearest floor” is transmitted to the monitoring center 25.

このように、かご5の最寄階への移動に支障が発生するほど地震の規模が大きい場合は、S波検出タイミングで「S波検出、地震発生、エレベータ運転中止」の情報fが送信されると共に、P波検出時刻(t=0)から一定時間TSを経過したタイミングで、かご5内への乗客の閉じ込め事故の可能性のある「かご、最寄階不到着」の重要な情報fと監視センター25へ送信されるので、乗客に対する安全性は十分確保される。 Thus, when the scale of the earthquake is so large that the movement of the car 5 to the nearest floor is hindered, the information f “S wave detection, earthquake occurrence, elevator stop” is transmitted at the S wave detection timing. In addition, at the timing when a certain time T S has elapsed from the P wave detection time (t = 0), important information on “cage, nearest floor non-arrival” that may cause a passenger confinement accident in the car 5 Since f is transmitted to the monitoring center 25, safety for passengers is sufficiently ensured.

図4に示すように、発生した地震の強度が低い場合においては、検出感度が150ガルと極端に低いS波検出器16からS波検出信号bが出力されることはない。しかし、検出感度が80ガルと十分に高いP波検出器13はP波検出信号aを出力する。したがって、P波検出と同時に(t=0)、管制運転cが開始され、経過時間t2にて、管制運転cが終了して、最寄階到着検出部19から最寄階到着情報dが出力されると、かご5の最寄階移動が正常に終了したことになる。 As shown in FIG. 4, when the intensity of the earthquake that has occurred is low, the S-wave detection signal b is not output from the S-wave detector 16 having an extremely low detection sensitivity of 150 gal. However, the P wave detector 13 having a sufficiently high detection sensitivity of 80 gal outputs the P wave detection signal a. Therefore, at the same time as the detection of the P wave (t = 0), the control operation c is started, and at the elapsed time t 2 , the control operation c is ended, and the nearest floor arrival information d is received from the nearest floor arrival detection unit 19. When it is output, the nearest floor movement of the car 5 is normally completed.

さらに、P波検出時刻(t=0)から例えば3分等の一定時間TAを経過した時点においてS波検出信号bは出力されていないので、エレベータ運転再開部21が起動して、最寄階到着情報dが出力されていることを確認の後、エレベータ通常運転部9へエレベータ通常運転の再開を指示して、エレベータ運転状態eへ移行させる。さらに、エレベータ運転再開部21は、「地震発生、その後、エレベータ運転再開」の情報fを監視センター25へ送信する。 Further, since the S wave detection signal b is not output at the time when a certain time T A such as 3 minutes has elapsed from the P wave detection time (t = 0), the elevator operation resuming unit 21 is activated, and the nearest After confirming that the floor arrival information d is output, the elevator normal operation section 9 is instructed to resume the elevator normal operation, and the elevator operation state e is shifted to. Further, the elevator operation resuming unit 21 transmits information f “Earthquake, then elevator operation resumed” to the monitoring center 25.

なお、図5に示すように、かご5の最寄階への移動に支障が発生するほど規模の大きな地震が発生したが、例えばS波検出器16が故障してS波検出信号bが出力されないとき、又は、S波検出器16からS波検出信号bが出力されないほど小さな地震であるが、何らかの要因にて、かご5の最寄階への移動に支障が生じた場合には、管制運転部14がP波検出(t=0)に同期して、管制運転cを開始するが、かご5が最寄階に到着しないので、最寄階到着情報dが出力されることはない。その結果、P波検出時刻(t=0)から2分等の一定時間TAを経過した時点において、エレベータ運転再開部21がエレベータの運転再開を指示することはない。そして、P波検出時刻(t=0)から5分等の一定時間TBを経過した時点において、最寄階到着情報dは出力されない状態であるので、最寄階不到着判定部23は、監視センター25へ「かご、最寄階不到着」の情報fを送信する。 As shown in FIG. 5, an earthquake that is large enough to hinder the movement of the car 5 to the nearest floor occurred. For example, the S wave detector 16 fails and the S wave detection signal b is output. If the earthquake does not occur or the earthquake is so small that the S wave detection signal b is not output from the S wave detector 16, but the movement of the car 5 to the nearest floor is hindered for some reason, Although the driving unit 14 starts the control operation c in synchronization with the P wave detection (t = 0), the nearest floor arrival information d is not output because the car 5 does not arrive at the nearest floor. As a result, at the time has elapsed for a predetermined time T A of the 2 minutes, such as from P-wave detection time (t = 0), does not elevator operation resumption section 21 instructs the operation resumption of the elevator. At a time after the elapse of a predetermined time T B of 5 minutes or the like from the P-wave detection time (t = 0), since the nearest floor arrival information d is in a state of not outputted, nearest floor not arrive determination unit 23, Information “c, no arrival at the nearest floor” is transmitted to the monitoring center 25.

このように、たとえ、S波検出信号bが出力されなかったとしても、かご5が最寄階へ到着していなければ、エレベータは運転再開されない。   Thus, even if the S wave detection signal b is not output, the elevator is not restarted unless the car 5 has arrived at the nearest floor.

図6はこのように構成されたエレベータの地震監視装置の全体動作を示す流れ図である。   FIG. 6 is a flowchart showing the overall operation of the elevator earthquake monitoring apparatus constructed as described above.

P波検出器13がP波を検出すると(ステップS1)、経過時間tの初期化(T=0)を実施する(S2)。さらに、管制運転cを開始する(S3)。P波検出器13のP波検出からの経過時間tが2分等の一定時間TAを経過する前に(S5)、S波検出がS波を検出すると(S4)、「地震発生、エレベータ運転中止」の情報を監視センター25へ通知(送信)する(S6)。その後、経過時間tが5分の猶予時間TBに達する前(S8)に、かご5の最寄階到着が確認できると(S7)、実際にエレベータの運転を中止する(S10)。 When the P wave detector 13 detects the P wave (step S1), initialization of the elapsed time t (T = 0) is performed (S2). Furthermore, the control operation c is started (S3). If the S wave detection is detected by the S wave detection (S4) before the elapse time t from the P wave detection of the P wave detector 13 passes the fixed time T A such as 2 minutes (S5), “Earthquake, elevator” The information “operation stop” is notified (transmitted) to the monitoring center 25 (S6). Then, before (S8) the elapsed time t reaches the 5 minute window time T B, the nearest floor arrival of the car 5 can be confirmed (S7), actually stops the operation of the elevator (S10).

また、経過時間tが5分の猶予時間TBを経過しても、かご5の最寄階到着が確認できない場合は(S8)、監視センター25へ「かご、最寄階不到着」の情報fを送信する(S9)。そして、実際にエレベータの運転を中止する(S10)。 In addition, even after the lapse of the elapsed time t is 5 minutes of grace time T B, if the nearest floor arrival of the cage 5 can not be confirmed (S8), information of the "cage, the nearest floor non-arrival" to the monitoring center 25 f is transmitted (S9). Then, the elevator operation is actually stopped (S10).

S5にて、P波検出器13のP波の検出からの経過時間tが2分等の一定時間TAを経過しても、S波検出がS波を検出しないと、この時点で、かご5が最寄階に到着しているか否かを調べる(S11)。かご5が最寄階に到着している場合は、エレベータの運転を再開し(S12)、監視センター25へ、「地震発生、その後、エレベータ運転再開」を通知する(S13)。この時点でかご5が最寄階に到着してないと、かご5が最寄階に到着するのを待って、S12、S13へ進む。 At S5, even after the lapse of a predetermined time T A, such as 2 minutes elapsed time t from the detection of the P wave of P-wave detector 13, the S-wave detection does not detect the S-wave, at this point, the car It is checked whether 5 has arrived at the nearest floor (S11). When the car 5 has arrived at the nearest floor, the operation of the elevator is resumed (S12), and the monitoring center 25 is notified of "the occurrence of an earthquake and then the resumption of the elevator operation" (S13). If the car 5 has not arrived at the nearest floor at this time, it waits for the car 5 to arrive at the nearest floor, and proceeds to S12 and S13.

そして、経過時間tが5分の猶予時間TBを経過しても、かご5の最寄階到着が確認できない場合は(S14)、監視センター25へ「かご、最寄階不到着、エレベータ運転中止」の情報fを送信する(S15)。そして、実際にエレベータの運転を中止する(S16)。 And, even after the elapse of the elapsed time t is 5 minutes of grace time T B, if the nearest floor arrival of the cage 5 can not be confirmed (S14), "the car to the monitoring center 25, the nearest floor non-arrival, the elevator operation The “stop” information f is transmitted (S15). Then, the operation of the elevator is actually stopped (S16).

このように構成されたエレベータの地震監視制御においては、P波検出器13がP波検出信号aを出力した時点(t=0)では監視センター25への通報は行わずに、さらにS波検出器16からS波検出信号bが出力されない場合には、一定時間TA後にエレベータが通常運転を再開し、そのエレベータ運転再開が監視センター25へ通知される。一方、S波検知器16からS波検出信号bが出力された場合は、S波検出とエレベータ運転中止が監視センター25へ通知される。 In the earthquake seismic control of the elevator configured as described above, at the time when the P wave detector 13 outputs the P wave detection signal a (t = 0), the notification to the monitoring center 25 is not performed and the S wave detection is further performed. when the vessel 16 does not output the S-wave detection signal b, the elevator resumes normal operation after a predetermined time T a, the elevator operation resumption is notified to the monitoring center 25. On the other hand, when the S wave detection signal b is output from the S wave detector 16, the monitoring center 25 is notified of the S wave detection and the elevator operation stop.

このようにして、地震発生時において、エレベータは監視センター25に対して、重要な情報の1回の報知を実施するのみである。よって、監視センター25においては、地震発生時のエレベータの状況を把握することができ、監視センター25への回線輻輳や監視センター25の情報処理量増大を抑制することができる。   In this way, when an earthquake occurs, the elevator only performs one notification of important information to the monitoring center 25. Therefore, the monitoring center 25 can grasp the state of the elevator at the time of the earthquake occurrence, and can suppress the line congestion to the monitoring center 25 and the increase in the information processing amount of the monitoring center 25.

また、P波が検出されて、管制運転cが実行されたときに、かご5が最寄階に到達しない場合は、最寄階不到着の情報が監視センター25へ通知される。このように、かごの乗客の安全性に関する重要な情報は、その都度確実に監視センター25へ送信される。   In addition, when the car 5 does not reach the nearest floor when the P wave is detected and the control operation c is executed, the monitoring center 25 is notified of information on the arrival of the nearest floor. In this way, important information related to the safety of passengers in the car is reliably transmitted to the monitoring center 25 each time.
