Abstract

<P>PROBLEM TO BE SOLVED: To prevent the evacuating passengers from being blocked in by a fire shutter when an elevator car is moved to an evacuation floor. <P>SOLUTION: This system detects a fire in the step S1, determines if the fire shutter on the first evacuation floor is closed in the step S3, and moves the car to the first evacuation floor if the fire shutter is not closed in the step S4. If the fire shutter is closed, the car is moved to the second evacuation floor in the step S5. In both cases, the door is opened and then closed, and thereafter the operation is suspended. If the system detects that the fire shutter on the destination floor is closed during the operation and that the passengers are in the car, an announcement of a further move is given inside the car and the car is moved to a floor on which a fire shutter is not closed. <P>COPYRIGHT: (C)2004,JPO

この発明は、防火シャッタ付きビルの火災時にエレベーターを運転する装置に関するものである。
【０００２】
【従来の技術】
従来のエレベーターの火災時運転装置においては、避難階で戸閉休止中のかご内に乗客が閉じ込められていることを乗客検出装置が検出すると、かご内に乗客避難手順を放送装置により放送し、戸開閉を繰り返す。これでも降車がなければ、通信装置により監視センタに通報したり、管理人室に警報を発したりする。（例えば、特許文献１）

特開平５−１１６８５７号公報（第３〜第４頁、図１）
【０００４】
【発明が解決しようとする課題】
従来のエレベーターの火災時運転装置では、避難階で休止中のかご内に乗客が閉じ込められていることが検出されると、戸開閉を繰り返すようにしているため、乗客に脱出を促すことはできるが、乗場に設置された防火シャッタが降りている場合には、かごが停止している状態で戸開閉を繰り返しても、乗客は乗場に降車することはできず、閉じ込められたままとなるという問題点がある。
【０００５】
この発明は上記問題点を解消するためになされたもので、防火シャッタ付きのビルでも、火災発生時乗客を確実に救出できるようにするエレベーターの火災時運転装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
この発明に係るエレベーターの火災時運転装置は、各階の乗場に防火シャッタが設けられたエレベーターにおいて、火災発生を検出する火災感知器及び上記防火シャッタの状態を検出する防火シャッタ検出器を設け、上記火災が検出されると、上記エレベーターのかごを上記防火シャッタが降りていないと検出された所定避難階へ走行させた後、その階で運転休止させるかご運転制御手段を備えたものである。
【０００７】
【発明の実施の形態】
実施の形態１．
図１〜図５はこの発明の第１〜第４発明の一実施の形態を示す図で、図１は全体構成図、図２は昇降路縦断面図、図３は避難動作フローチャート、図４は運転休止後の動作フローチャート、図５は避難階不到着時のフローチャートである。
【０００８】
図１において、火災感知器１の状態は火災検出手段２で検出される。また、階床ごとに設置された防火シャッタの状態は防火シャッタ検出器３で検出され、防火シャッタ検出手段４でどの階の防火シャッタ検出器３が動作しているかを検出する。かご運転制御手段５は火災検出手段２の出力及び防火シャッタ検出手段４の出力と、かご位置検出手段６で検出されたかご位置から防火シャッタの降りていない階へかごを運転する。
【０００９】
また、かごを避難させた後にその階のシャッタが降りたとき、又は何らかの異常で避難階に到着できず、シャッタの降りた階に停止したとき、乗車検出手段７によりかご内に乗客がいることが検出されると、かご運転制御手段５によりシャッタの降りていない階まで走行する。また、発報制御手段８により乗客に表示又はアナウンスをする。
【００１０】
図２において、かご１１と階床の関係を示し、第１避難階は２階２Ｆ、第２避難階は３階３Ｆとする。この例では、１階１Ｆの防火シャッタ１２が降りているとする。かご１１は第１避難階である２階２Ｆに向かって走行している。
【００１１】
次に、この実施の形態の動作を図３〜図５を参照して説明する。
（１）火災時の避難階動作（図３）
ステップＳ１で火災検出手段２が火災感知器１の動作を検出したかを判断する。火災感知器１が動作していなければ、ステップＳ２でエレベーターの運転は継続される。火災感知器１が動作していれば、ステップＳ３で防火シャッタ検出手段４が第１避難階２Ｆの防火シャッタが降りているかを判断する。
【００１２】
第１避難階２Ｆの防火シャッタが降りていない場合は、ステップＳ４へ進み、かご運転制御手段５はかご１１を第１避難階２Ｆへ走行させる。第１避難階２Ｆの防火シャッタが降りている場合は、ステップＳ５へ進み、第２避難階３Ｆへかご１１を走行させる。この後、ステップＳ６でかご１１の戸を開き、ステップＳ７で所定時間経過後戸を閉める。そして、ステップＳ８でかご１１内で戸開ボタンが押されたか、すなわち乗客がいるかを判断し、戸開ボタンが押されたらステップＳ６へ戻り、押されなければ運転休止となる。
【００１３】
ここで、ステップＳ１〜Ｓ９はかご運転制御手段５を構成している。
このようにして、防火シャッタ付きのビルで火災が発生したとき、かご１１を防火シャッタの降りていない避難階へ走行させるようにしたため、乗客を確実に避難させることが可能となる。
【００１４】
（２）運転休止後の動作（図４）
ステップＳ１１でかご１１は運転休止中とする。ステップＳ１２でかご１１が停止している階の防火シャッタが降りているかを判定する。防火シャッタが降りていればステップＳ１３へ進み、乗車検出手段７がかご１１内に乗客がいることを検出したかを判断する。この判断の手段としては、かご負荷、戸開ボタン操作の有無、専用ボタンの設置等が考えられるが、特に限定はしない。乗客がいないと判断すると、ステップＳ１２へ戻る。乗客がいると判断すると、ステップＳ１４へ進み、アナウンス、表示等によって、かご１１が防火シャッタの降りていない階まで走行することを乗客に報知する。
【００１５】
ステップＳ１５で第１避難階２Ｆ以外の各階に防火シャッタ検出器３が設置されているかを判断する。各階に防火シャッタ検出器３が設置されている場合は、ステップＳ１６へ進み、防火シャッタが降りていない階までかご１１を走行させて、ステップＳ１９で運転休止となる。第１避難階２Ｆ以外は防火シャッタ検出器３が設置されていない場合は、ステップＳ１７へ進み、最寄り階までかご１１を走行させる。その後、ステップＳ１８でかご１１内に乗客がいるかを判断する。
【００１６】
かご１１内に乗客がいると判断すると、ステップＳ１７へ戻り、乗客がかご内１１内にいなくなるまで、最寄り階走行を継続する。乗客がいなくなれば、ステップＳ１９で運転休止となる。
ここで、ステップＳ１１〜Ｓ１３は再走行条件検出手段を、ステップＳ１４は発報制御手段８を、ステップＳ１５は防火シャッタ検出器有無検出手段を、ステップＳ１６〜Ｓ１９は再走行指令手段を構成している。
このようにして、防火シャッタ付きのビルで火災が発生し、かご１１が避難階に到着して運転休止となった後、防火シャッタが降りた場合でも、かご１１は再走行して防火シャッタが降りていない階に停止するため、乗客を確実に避難させることが可能となる。
【００１７】
（３）避難階不到着時の動作（図５）
図３の動作により、かご１１を第１又は第２避難階２Ｆ，３Ｆへ走行させたが、何らかの異常で第１又は第２避難階２Ｆ，３Ｆまでかごが到着できず、途中の階に停止し、運転休止したとする。
ステップＳ２１で運転休止とする。ステップＳ２２でかご１１内に乗客がいるかを判断する。乗客がいないと判断すると、ステップＳ２３で運転休止を継続する。また、乗客がいると判断すると、ステップＳ２４へ進み、かご１１が停止している階の防火シャッタが降りているかを判断する。
【００１８】
防火シャッタが降りていると判断すると、ステップＳ２５へ進み、エレベーターが走行可能であるかを判断し、走行可能であればステップＳ２６へ進む。ステップＳ２６で第１避難階２Ｆの防火シャッタが降りているかを判断し、降りていない場合は、ステップＳ２７で第１避難階２Ｆへかご１１を走行させ、降りている場合はステップＳ２８で第２避難階３Ｆへかご１１を走行させ、それぞれステップＳ２９で運転休止となる。
【００１９】
ここで、ステップＳ２２、Ｓ２４は再走行条件検出手段を、ステップＳ２５〜Ｓ２８は再走行指令手段を構成している。
このようにして、防火シャッタ付きのビルで火災が発生し、かご１１が避難階へ走行したが、なんらかの異常で避難階に到着できなかった場合でも、かご１１は再走行して、防火シャッタが降りていない階に停止するため、乗客を確実に避難させることが可能となる。
【００２０】
【発明の効果】
以上説明したとおりこの発明では、火災が検出されると、エレベーターのかごを防火シャッタが降りていないと検出された所定避難階へ走行させた後、その階で運転休止させるようにしたので、防火シャッタ付きのビルで火災が発生したとき、乗客を確実に避難させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for operating an elevator when a building with a fireproof shutter fires.
[0002]
[Prior art]
In a conventional elevator fire driving device, when the passenger detection device detects that a passenger is trapped in a car with doors closed on the evacuation floor, the passenger evacuation procedure is broadcasted in the car by a broadcasting device, Repeat opening and closing the door. If there is still no getting off, the communication device notifies the monitoring center or issues an alarm to the manager's office. (For example, Patent Document 1)
[0003]
[Patent Document 1]
JP-A-5-116857 (pages 3 and 4, FIG. 1)
[0004]
[Problems to be solved by the invention]
With the conventional elevator fire driving device, when it is detected that a passenger is trapped in a car at rest on the evacuation floor, the door is repeatedly opened and closed, so that the passenger can be prompted to escape. However, if the fire prevention shutter installed at the landing is down, even if the car is stopped, even if the door is repeatedly opened and closed, the passenger can not get off at the landing and remains trapped There is a problem.
[0005]
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a fire operating device for an elevator capable of reliably rescuing passengers in the event of a fire even in a building with a fire shutter.
[0006]
[Means for Solving the Problems]
An elevator fire driving device according to the present invention is provided with a fire sensor for detecting the occurrence of a fire and a fire shutter detector for detecting a state of the fire shutter in an elevator in which a fire shutter is provided at a landing on each floor. When a fire is detected, the elevator car is provided with a car operation control means for driving the elevator car to a predetermined evacuation floor where it is detected that the fire prevention shutter has not been lowered and then stopping the operation at that floor.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
1 to 5 show one embodiment of the first to fourth inventions of the present invention. FIG. 1 is an overall configuration diagram, FIG. 2 is a vertical sectional view of a hoistway, FIG. Is a flowchart of the operation after the operation is suspended, and FIG. 5 is a flowchart when the evacuation floor does not arrive.
[0008]
In FIG. 1, the state of the fire detector 1 is detected by the fire detection means 2. Further, the state of the fireproof shutter installed on each floor is detected by the fireproof shutter detector 3, and the fireproof shutter detector 3 detects which fireproof shutter detector 3 is operating. The car operation control means 5 drives the car from the output of the fire detection means 2 and the output of the fire protection shutter detection means 4 and the car position detected by the car position detection means 6 to a floor where the fire protection shutter is not lowered.
[0009]
In addition, when the shutter on the floor is lowered after the car is evacuated, or when the vehicle cannot reach the evacuation floor due to some abnormality and stops on the floor from which the shutter has been released, passengers in the car are detected by the boarding detection means 7. Is detected, the car operation control means 5 travels to the floor where the shutter is not lowered. The alert control means 8 displays or announces to the passenger.
[0010]
In FIG. 2, the relationship between the car 11 and the floors is shown, where the first evacuation floor is the second floor 2F and the second evacuation floor is the third floor 3F. In this example, it is assumed that the fireproof shutter 12 on the first floor 1F is down. The car 11 is traveling toward the first evacuation floor, the second floor 2F.
[0011]
Next, the operation of this embodiment will be described with reference to FIGS.
(1) Evacuation floor operation in case of fire (Fig. 3)
In step S1, it is determined whether the fire detecting means 2 has detected the operation of the fire detector 1. If the fire detector 1 is not operating, the operation of the elevator is continued in step S2. If the fire detector 1 is operating, in step S3, the fire shutter detection means 4 determines whether the fire shutter of the first evacuation floor 2F is down.
[0012]
If the fireproof shutter of the first evacuation floor 2F has not been lowered, the process proceeds to step S4, and the car operation control means 5 causes the car 11 to travel to the first evacuation floor 2F. When the fire prevention shutter of the first evacuation floor 2F is down, the process proceeds to step S5, and the car 11 is caused to travel to the second evacuation floor 3F. Thereafter, the door of the car 11 is opened in step S6, and the door is closed after a predetermined time has elapsed in step S7. Then, in step S8, it is determined whether or not the door open button has been pressed in the car 11, that is, whether or not there is a passenger. If the door open button is pressed, the process returns to step S6. If not, the operation is suspended.
[0013]
Here, steps S1 to S9 constitute the car operation control means 5.
In this way, when a fire occurs in a building with a fireproof shutter, the car 11 is caused to travel to the evacuation floor where the fireproof shutter is not lowered, so that passengers can be evacuated reliably.
[0014]
(2) Operation after suspension of operation (Fig. 4)
In step S11, the car 11 is in operation suspension. In step S12, it is determined whether or not the fire prevention shutter on the floor where the car 11 is stopped is down. If the fire prevention shutter has been released, the process proceeds to step S13, and it is determined whether or not the boarding detection means 7 has detected that there is a passenger in the car 11. As means for this determination, a car load, the presence or absence of a door opening button operation, the installation of a dedicated button, and the like can be considered, but there is no particular limitation. When it is determined that there is no passenger, the process returns to step S12. When it is determined that there is a passenger, the process proceeds to step S14, and the passenger is informed that the car 11 is traveling to a floor where the fireproof shutter is not lowered by an announcement, a display, or the like.
[0015]
In step S15, it is determined whether or not the fireproof shutter detector 3 is installed on each floor other than the first evacuation floor 2F. When the fire prevention shutter detector 3 is installed on each floor, the process proceeds to step S16, in which the car 11 travels to the floor where the fire prevention shutter is not lowered, and the operation is suspended in step S19. When the fireproof shutter detector 3 is not installed on the floor other than the first evacuation floor 2F, the process proceeds to step S17, and the car 11 is driven to the nearest floor. Thereafter, it is determined whether there is a passenger in the car 11 in step S18.
[0016]
When it is determined that there is a passenger in the car 11, the process returns to step S17, and the nearest floor traveling is continued until the passenger is no longer in the car 11. If there are no more passengers, the operation is suspended in step S19.
Here, steps S11 to S13 constitute rerunning condition detecting means, step S14 constitutes the alarm control means 8, step S15 constitutes a fireproof shutter detector presence / absence detecting means, and steps S16 to S19 constitute rerunning instruction means. I have.
In this way, even if a fire occurs in a building with a fireproof shutter and the car 11 arrives at the evacuation floor and stops operating, and then the fireproof shutter falls, the car 11 re-runs and the fireproof shutter is released. Since the vehicle stops on a floor that has not been dismounted, passengers can be evacuated reliably.
[0017]
(3) Operation when the evacuation floor does not arrive (Fig. 5)
The car 11 was moved to the first or second evacuation floor 2F, 3F by the operation of FIG. 3, but the car could not arrive at the first or second evacuation floor 2F, 3F due to some abnormality, and stopped at a middle floor. And the operation is stopped.
Operation is suspended in step S21. In step S22, it is determined whether there is a passenger in the car 11. If it is determined that there are no passengers, the driving suspension is continued in step S23. When it is determined that there is a passenger, the process proceeds to step S24, and it is determined whether or not the fire prevention shutter of the floor where the car 11 is stopped is down.
[0018]
If it is determined that the fire prevention shutter is down, the process proceeds to step S25, and it is determined whether the elevator can travel. If the elevator can travel, the process proceeds to step S26. In step S26, it is determined whether or not the fire prevention shutter of the first evacuation floor 2F has been lowered. If not, the car 11 is driven to the first evacuation floor 2F in step S27. The car 11 is caused to travel to the evacuation floor 3F, and the operation is suspended in step S29.
[0019]
Here, steps S22 and S24 constitute rerunning condition detecting means, and steps S25 to S28 constitute rerunning instruction means.
In this manner, a fire occurred in a building with a fire shutter, and the car 11 traveled to the evacuation floor. However, even if the car 11 could not reach the evacuation floor due to some abnormality, the car 11 re-runs and the fire shutter is released. Since the vehicle stops on a floor that has not been dismounted, passengers can be evacuated reliably.
[0020]
【The invention's effect】
As described above, according to the present invention, when a fire is detected, the elevator car is caused to travel to a predetermined evacuation floor where it is detected that the fire prevention shutter has not been released, and then to suspend operation at that floor. When a fire occurs in a building with a shutter, passengers can be evacuated reliably.
