従来技術として、特許文献1に記載されたエレベータ運転制御装置では、中間免震構造を有する建造物に設置されるエレベータにおいて、地震発生時に走行中のかごが最寄階へ到着、停止するまでに免震構造部を通るか否かを、走行中であるかごの現在位置及び走行方向と免震構造部の位置とから判断して運転を行うような制御方式が開示されている。   As the prior art, in the elevator operation control apparatus described in Patent Document 1, in an elevator installed in a building having an intermediate seismic isolation structure, when a traveling car arrives at the nearest floor and stops when an earthquake occurs A control method is disclosed in which operation is performed by judging whether or not the vehicle passes through the seismic isolation structure from the current position and traveling direction of the traveling car and the position of the seismic isolation structure.

Car position / speed / direction information from the means, the seismic isolation structure position information from the seismic isolation structure position storage means, and the emergency stop system from the emergency stop distance storage means And distance information, based on, the car is to avoid stopping the seismic isolation structure, i.e. a structure that the operation control so as to pass through or near the blind seismic isolation structure.

本発明によれば、地震発生時にエレベータの乗りかごを揺れの大きい免震構造部へ停止することを避けることで、乗客の安全確保を図ることができ、さらに、乗りかご等の機器の損傷を防止することができる。   According to the present invention, it is possible to ensure the safety of passengers by avoiding stopping the elevator car to the seismically isolated structure with large shaking in the event of an earthquake, and to further damage the equipment such as the car. Can be prevented.

図1において、本発明の実施形態に係るエレベータ制御装置10は、地震の揺れ検出装置からの揺れ検出信号1を検出する揺れ検出手段2と、建築物の免震部位置(図2の免震構造部25を参照)を記憶する免震部位置記憶手段3と、巻上げ機21の回転数、回転方向、位置情報を出力するエンコーダ22からのエンコーダ検出信号4を検出する乗りかご位置・速度・方向検出手段5と、非常停止した際の乗りかご制動距離を記憶する非常停止距離記憶手段6と、揺れ検出時に免震部位置記憶手段3と乗りかご位置・速度・方向検出手段5と非常停止距離記憶手段6の情報に基づき免震部位に乗りかごが停止することを回避する免震構造部回避運転制御手段7と、により構成されている。なお、免震構造部回避運転制御手段7は、免震構造部に乗りかごを停止するのを回避する運転制御を行うが、後述する図3の運転フローからも分かるように、当然のこととしてエレベータの通常の管制運転を制御する機能を備えているものである。   In FIG. 1, an elevator control device 10 according to an embodiment of the present invention includes a shake detection means 2 that detects a shake detection signal 1 from an earthquake shake detection device, and a seismic isolation portion position of a building (the seismic isolation portion of FIG. 2). The seismic isolation part position storage means 3 for storing the structure part 25) and the car position / speed / detector for detecting the encoder detection signal 4 from the encoder 22 for outputting the rotation speed, rotation direction and position information of the hoisting machine 21 Direction detection means 5, emergency stop distance storage means 6 for storing the car braking distance at the time of emergency stop, seismic isolation part position storage means 3, car position / speed / direction detection means 5 and emergency stop at the time of shaking detection It is constituted by seismic isolation structure part avoidance operation control means 7 for avoiding the car from stopping at the seismic isolation part based on the information of the distance storage means 6. The seismic isolation structure avoidance operation control means 7 performs operation control that avoids stopping the car in the seismic isolation structure, but as will be understood from the operation flow of FIG. It has a function to control the normal control operation of the elevator.

揺れ検出装置からの揺れ検出信号1は、一般的に用いられている地震感知器によるものでよいが、例えば緊急地震速報など建屋自身の揺れ検出装置によらない手段で与えられるものでもよい。   The shake detection signal 1 from the shake detection device may be based on a commonly used earthquake detector, but may be provided by means that do not depend on the building's own shake detection device, such as an emergency earthquake warning.

図2において、巻上げ機21の回転によるエンコーダ22の信号がエレベータ制御盤23に入力され、この制御盤23において乗りかご位置・速度・方向の算出が行わることにより、乗りかご24の走行を制御している。斜線部は、建築物において揺れの大きい免震構造部25を有する例を示している。制御盤23には、中央処理装置として機能するマイクロコンピュータ(CPU)26が内蔵されている。   In FIG. 2, a signal from the encoder 22 generated by the rotation of the hoisting machine 21 is input to the elevator control panel 23, and the traveling of the car 24 is controlled by calculating the car position / speed / direction in the control board 23. is doing. The hatched portion shows an example having the seismic isolation structure 25 having a large shaking in the building. The control panel 23 incorporates a microcomputer (CPU) 26 that functions as a central processing unit.

本実施形態に係るエレベータ制御装置における動作の概要を以下述べる。図3に地震発生時の管制運転に関するフローを示す。基本動作はエレベータ協会の地震時管制運転に因ったものである。   An outline of the operation of the elevator control apparatus according to this embodiment will be described below. Fig. 3 shows the flow related to control operation when an earthquake occurs. The basic operation is due to the Elevator Association's seismic control operation.

地震発生時、ステップS301とステップ302においてあらかじめ地震感知器に設定した特低ガル、低ガルの検出動作をしたかどうかを判定する。特低ガル検知が動作していない場合、ステップS4に進み運転を継続する。特低ガル検知が動作していた場合はステップS302に進む。   When an earthquake occurs, it is determined in steps S301 and 302 whether or not the special low-gull and low-gull detection operations set in advance in the earthquake detector have been performed. When the extra low gull detection is not operating, the operation proceeds to step S4 and the operation is continued. If the extra low gull detection is operating, the process proceeds to step S302.

ステップS302にて低ガル検知が動作していた場合はステップS303に進み、エレベータが走行中であるかどうか判定する。走行中でない場合はステップS5に進みエレベータを戸開する。走行中である場合はステップS304に進み安全回路の動作確認を行う。ここで、安全回路とはブレーキ異常動作検出、ドア開閉状態異常検出、かご速度異常動作検出用回路である。安全回路の内でどれか一つでも動作していた場合はステップS6に進みエレベータを非常停止させる(階途中で)。非常停止後ステップS305に進み安全回路が正常動作に復帰したかどうか判定する。復帰しない場合はステップS7に進み運転を休止する。   When the low-gull detection is operating in step S302, the process proceeds to step S303, and it is determined whether or not the elevator is traveling. If it is not running, the process proceeds to step S5 and the elevator is opened. If the vehicle is traveling, the process proceeds to step S304 to check the operation of the safety circuit. Here, the safety circuit is a circuit for detecting abnormal braking operation, detecting abnormal door opening / closing status, and detecting abnormal car speed operation. If any one of the safety circuits is operating, the process proceeds to step S6, and the elevator is emergency stopped (in the middle of the floor). After an emergency stop, the process proceeds to step S305 to determine whether the safety circuit has returned to normal operation. When not returning, it progresses to step S7 and stops driving | operation.

ステップS305で安全回路が正常に復帰した場合、もしくはステップS304で安全回路が動作していない場合はステップS306に進み、最寄階が免震構造位置であるかどうか判定する。   If the safety circuit has returned to normal in step S305, or if the safety circuit is not operating in step S304, the process proceeds to step S306 to determine whether the nearest floor is the seismic isolation structure position.

最寄階が免震構造部でないと判断した場合はステップS8に進み、エレベータを最寄階へ運転させ停止する(免震構造部である階に比べて、免震構造部でない階は揺れが大きくないから当該階に停止する)。最寄階へ停止後はステップS5でまず戸開動作をし、乗客を非難させる。その後ステップS307へ進み、かご内へ残った乗客が脱出できるようステップS307の判定を繰り返し行われる状態にして運転を休止させる。   If it is determined that the nearest floor is not a seismic isolation structure, the process proceeds to step S8, and the elevator is driven to the nearest floor and stopped (the floor that is not the seismic isolation structure is shaken compared to the floor that is the seismic isolation structure). Stop at the floor because it is not large). After stopping to the nearest floor, the door is first opened in step S5, and the passenger is accused. Thereafter, the process proceeds to step S307, and the operation is paused in a state where the determination of step S307 is repeatedly performed so that passengers remaining in the car can escape.

最寄階が免震構造部であると判断した場合はステップS310に進み、非常停止処理を行った場合に免震構造位置に停止となるかどうかを判定する。この判定は、走行中の現在速度、位置、運転方向と各速度において非常停止した場合の制動距離により判断するものであり、免震位置に至らずに停止しない(免震位置の手前止まり)と判断されれば、ステップS10に進みエレベータを非常停止させる(階途中で)。   If it is determined that the nearest floor is the seismic isolation structure, the process proceeds to step S310, and it is determined whether or not the emergency isolation process is stopped when the emergency stop process is performed. This determination is based on the current speed during travel, position, driving direction, and braking distance in the case of emergency stop at each speed, and does not stop before reaching the seismic isolation position (stop before the seismic isolation position). If judged, it will progress to Step S10 and will make an emergency stop of the elevator (in the middle of the floor).

免震位置に停止すると判断すればステップS311へ進み免震部位を通過するように運転を継続する。ここで、運転継続中は免震構造部通過可能位置となるまでステップS312、S313で安全回路の動作状態の判定を繰り返し行う。免震部位置通過判定後は先のステップS8へ進みエレベータを最寄階へ運転させ停止する。   If it is determined to stop at the seismic isolation position, the process proceeds to step S311 and the operation is continued so as to pass the seismic isolation part. Here, while the operation is continued, the operation state of the safety circuit is repeatedly determined in steps S312 and S313 until the seismic isolation structure portion can be passed. After the seismic isolation part position passage determination, the process proceeds to the previous step S8 to drive the elevator to the nearest floor and stop.

ここで、ステップS301からステップ306、ステップS310〜ステップS313、ステップS10を経てステップS8までの動作を図1に示すエレベータ制御装置との関連で繰り返して説明する。建築物に中間免震構造部25を有していてその構造部25の位置を免震部位置記憶手段3に記憶しておき、非常停止による乗りかごの制動距離を非常停止距離記憶手段6に記憶しておき、図1に示す揺れ検出手段2により特低ガルと低ガルが動作したことを検知したときに、免震構造部回避運転制御手段7は、揺れ検出手段2による揺れ検出時に乗りかごを最寄階に停止させる管制運転の際に、乗りかごの位置・速度・方向検出手段5による乗りかごの走行情報と、免震部位置記憶手段3からの免震構造部25の位置情報と、非常停止距離記憶手段6からの非常停止距離情報と、に基づいて、乗りかご24が免震構造部25に停止することを回避するように運転制御するものである。   Here, the operation from step S301 to step 306, step S310 to step S313, step S10 to step S8 will be described repeatedly in relation to the elevator control device shown in FIG. The building has an intermediate seismic isolation structure 25, the position of the structure 25 is stored in the seismic isolation position storage means 3, and the braking distance of the car due to an emergency stop is stored in the emergency stop distance storage 6. The seismic isolation structure avoidance operation control means 7 is detected when the shake detection means 2 detects a shake when the shake detection means 2 shown in FIG. During the control operation to stop the car at the nearest floor, the traveling information of the car by the position / speed / direction detection means 5 of the car and the position information of the seismic isolation structure part 25 from the seismic isolation part position storage means 3 On the basis of the emergency stop distance information from the emergency stop distance storage means 6, operation control is performed so as to prevent the car 24 from stopping at the seismic isolation structure 25.

その運転制御を具体的に説明すると、揺れ検出時に最寄階が免震構造部25であると判定した場合(図3のS306でYES)、免震構造部の位置情報と非常停止距離情報に基づき免震構造部25の手前で非常停止可能位置と判定した場合は、乗りかご24を階途中で非常停止させること(図3のS10)、揺れ検出時に最寄階が免震構造部25であると判定した場合(図3のS310でYES)、免震構造部の位置情報と非常停止距離情報に基づき非常停止不可能位置と判定した場合は、乗りかご24が免震構造部を通過させて、次の最寄階へ停止処理(図3のS8)もしくはその後非常停止させること(図3には不図示であるが免震構造部通過後に非常停止させることは可能である)、である。このように、揺れを検知しエレベータが走行中のときに、最寄階が免震構造部である場合、種々の運転条件や動作態様を加味して免震構造部を通過又は手前止まりとなるように運転を制御するものである。   The operation control will be specifically described. When it is determined that the nearest floor is the seismic isolation structure 25 at the time of shaking detection (YES in S306 in FIG. 3), the position information and the emergency stop distance information of the seismic isolation structure are included. If it is determined that an emergency stop is possible in front of the seismic isolation structure 25, the car 24 is stopped in the middle of the floor (S10 in FIG. 3), and the nearest floor is the seismic isolation structure 25 when shaking is detected. If it is determined that there is an emergency stop impossible position based on the position information of the base isolation structure and the emergency stop distance information (YES in S310 in FIG. 3), the car 24 passes the base isolation structure. Then, stop processing to the next nearest floor (S8 in FIG. 3) or emergency stop thereafter (it is not shown in FIG. 3, but it is possible to make an emergency stop after passing through the seismic isolation structure). . In this way, when the nearest floor is the seismic isolation structure when the swing is detected and the elevator is traveling, it passes through the seismic isolation structure in consideration of various operating conditions and operation modes or stops at the front. So that the operation is controlled.

翻って、ステップS302にて低ガル検知が動作をしていない場合、ステップS320に進み、エレベータが走行中であるかどうか判定する。走行中でない場合はステップS13に進みエレベータ乗りかごを戸開する。走行中である場合はステップS321に進み安全回路の動作確認を行う。ここで、安全回路とは上述したものと同一であり、この安全回路の内でどれか一つでも動作していた場合はステップS11に進みエレベータを非常停止させる(階途中で)。非常停止後ステップS322に進み安全回路が正常動作に復帰したかどうか判定する。復帰しない場合はステップS7に進み運転を休止する。   On the other hand, if the low-gull detection is not operating in step S302, the process proceeds to step S320, and it is determined whether the elevator is traveling. If it is not running, the process proceeds to step S13 and the elevator car is opened. If the vehicle is traveling, the process proceeds to step S321 to check the operation of the safety circuit. Here, the safety circuit is the same as described above, and if any one of the safety circuits is operating, the process proceeds to step S11 and the elevator is emergency stopped (in the middle of the floor). After an emergency stop, the process proceeds to step S322 to determine whether the safety circuit has returned to normal operation. When not returning, it progresses to step S7 and stops driving | operation.

ステップS322で安全回路が正常に復帰した場合、もしくはステップS321で安全回路が動作していない場合はステップS12へ進み、最寄階へ運転させ戸開する(ステップS13)。その後ステップS323へ進み、かご内へ残った乗客が脱出できるようにステップS323の判定を繰り返し、ステップS324にて特低ガル検知の動作が手動もしくは自動リセット処理すればステップS9へ進み、エレベータは平常運転となる。   If the safety circuit returns to normal in step S322, or if the safety circuit is not operating in step S321, the process proceeds to step S12, and the door is driven to the nearest floor (step S13). Thereafter, the process proceeds to step S323, and the determination in step S323 is repeated so that passengers remaining in the car can escape. If the operation of the extra low gull detection is performed manually or automatically in step S324, the process proceeds to step S9, and the elevator is normal. It becomes driving.

以上述べたように、本実施形態において地震感知器が低ガル検知した際において、エレベータが走行中であれば、走行中の現在速度、現在位置、運転方向、当該速度での非常停止制動距離(予め求められている距離であり非常停止距離記憶手段6に格納されている)により免震構造部の部位(箇所)に停止するかどうかを判断し、停止すると判断されれば免震構造部を回避するまで運転を継続させ、その後最寄階運転を行わせる。また、停止しないと判断されれば非常停止させるように運転を制御するようにしているため、免震構造部への停止を回避でき、乗客の安全確保及び乗りかご、塔内機器の損傷を防ぐ効果が得られる。   As described above, when the earthquake detector detects low-gull in this embodiment, if the elevator is traveling, the current speed during traveling, the current position, the driving direction, and the emergency stop braking distance ( Whether or not to stop at a part (location) of the seismic isolation structure by a predetermined distance (stored in the emergency stop distance storage means 6). Continue driving until you avoid it, and then drive the nearest floor. In addition, since the operation is controlled so as to make an emergency stop if it is determined not to stop, the stop to the seismic isolation structure can be avoided, ensuring the safety of passengers and preventing damage to the car and tower equipment. An effect is obtained.
