【発明の属する技術分野】
この発明は、エレベータの制御装置に関するもので、特に、かごの戸の開動作時に、乗客の手や指等がかごの戸とかごの出入口柱との隙間に引き込まれることを未然に防止するためのものである。
【0002】
【従来の技術】
図4は従来のエレベータの制御装置の構成を説明するための模式図である。
図4において、1はかご、2はかごの戸、3はかごの戸2を開閉するための戸開閉機構、4はかご1に設置されたスピーカ、5は戸開閉機構3の開閉動作を制御するとともに、後述するアナウンス装置6を制御してスピーカ4を介して乗客にメッセージを報知する制御盤、6はスピーカ4を介して乗客に報知するメッセージ内容を格納するアナウンス装置、7はかごの床、8はかごの床7の下部に設置されて、かごの床7を支持するかご床支持板、9はかごの床7とかご床支持板9と間に介装された防振ゴム、10はかごの戸2付近のかごの床7に埋設されたフロアマットセンサであり、このフロアマットセンサ10は静電容量の変化によりフロアマットセンサ10上に乗客がいるか否かを検出する。
【0003】
この従来のエレベータの制御装置においては、制御盤5がかご1の着床を認識すると、フロアマットセンサ10からの乗客検出信号に基づいてフロアマットセンサ10上に乗客がいるか否かを判定する。
そして、制御盤5は、乗客がフロアマットセンサ10上に乗っていると判定すると、アナウンス装置6に格納されているメッセージ、例えば「ドアが開きます。ご注意ください。」のメッセージをスピーカ4から流す。これにより、かごの戸2付近にいた乗客は、かごの戸2の開動作の開始を察知し、かごの戸2から離れる。そこで、制御盤5は、戸開閉機構3を制御して、かごの戸2の開動作を行う。これにより、乗客の手や指等がかごの戸2とかごの出入口柱との隙間に引き込まれることが未然に防止される。
また、制御装置5は、乗客がフロアマットセンサ10上に乗っていないと判定すると、戸開閉機構3を制御して、かごの戸2の開動作を行う。
【0004】
【発明が解決しようとする課題】
この従来のエレベータの制御装置では、以上述べたように、フロアマットセンサ10をかごの戸2付近のかごの床7に埋設して、乗客がかごの戸2付近にいることを検出するようにしている。そこで、このフロアマットセンサ10は特殊なセンサであり、高価なものであるとともに、フロアマットセンサ10を埋設できるようにかごの床7を特殊な構造にしなければならず、低コスト化が図れないという課題があった。
【0005】
この発明は、上記の課題を解消するためになされたもので、かごの床とかご床支持板との間の四隅に介装された弾性部材の弾性変形量を安価なはかり装置を用いて検出し、制御手段によりはかり装置の検出信号に基づいて乗客がかごの戸付近にいるか否かを判定し、乗客がかごの戸付近にいると判定された場合に、戸開動作の開始を乗客にアナウンスするようにし、かごの戸とかごの出入口柱との隙間に手や指等が引き込まれることを未然に防止できる安価なエレベータの制御装置を提供するものである。
【0006】
【課題を解決するための手段】

【0007】
また、上記制御手段は、上記はかり装置の検出信号に基づいて乗客の総重量を算出し、該乗客の総重量がかごの許容最大搭載重量の1/2以上となった場合に乗客がかごの戸付近にいると判定するものである。
【0008】
また、上記制御手段は、かごの戸側の上記はかり装置の検出信号に基づいて乗客の第1重量を算出し、かつ、反かごの戸側の上記はかり装置の検出信号に基づいて乗客の第2重量を算出し、乗客の第1重量>乗客の第2重量となった場合に乗客がかごの戸付近にいると判定するものである。
【0009】
また、上記制御手段は、上記はかり装置の検出信号に基づいて乗客の乗りすぎか否かを判定し、乗客の乗りすぎと判定した場合には、上記アナウンス手段を動作させて乗客の乗りすぎを乗客に報知するとともに、上記かごの戸の閉動作を制止するように上記戸開閉機構を制御する機能を備えているものである。
【0010】
【発明の実施の形態】
以下、この発明の実施の形態を図について説明する。
実施の形態1.
図1はこの発明の実施の形態1に係るエレベータの制御装置の構成を説明する模式図、図2はこの発明の実施の形態1に係るエレベータの制御装置におけるかごの戸付近の乗客の有無の判定動作を説明するフローチャート、図3はこの発明の実施の形態1に係るエレベータの制御装置の動作を説明するフローチャートである。
【0011】
図1において、1はかご、2はかごの戸、3はかごの戸2を開閉するための戸開閉機構、4はかご1に設置されたアナウンス手段としてのスピーカ、6はスピーカ4を介して乗客に報知するメッセージ内容を格納するアナウンス手段としてのアナウンス装置、7はかごの床、8はかごの床7の下部に設置されて、かごの床7を支持するかご床支持板、9はかごの床7の四隅の位置でかごの床7とかご床支持板8と間に介装された弾性部材としての防振ゴム、11はかご床支持板8上に各防振ゴム9に近接して配設され、乗客の重量に起因する各防振ゴム9の弾性変形量を検出するはかり装置、12は戸開閉機構3の開閉動作を制御するとともに、はかり装置11の検出信号に基づいてアナウンス装置6を制御してスピーカ4を介して乗客にメッセージを報知する制御手段としての制御盤である。
【0012】
つぎに、制御盤12によるかごの戸付近の乗客の有無の判定動作について図2を参照しつつ説明する。
乗客がかご1に乗りこむと、かごの床7の四隅に配設された防振ゴム9がそれぞれ乗客の重量に応じて弾性変形する。この防振ゴム9の弾性変形量がはかり装置11により検出され、その検出信号が制御盤12に出力される。
制御盤12では、各はかり装置11の検出信号を入力し、4つの検出信号から乗客の総重量(W)を算出し、かごの戸2側の2つのはかり装置11の検出信号から乗客の第1重量(Wf)を算出し、反かごの戸2側の2つのはかり装置11の検出信号から乗客の第2重量(Wr)を算出している(ステップw1)。
そして、制御盤12は、乗客の総重量(W)がかご1の許容最大積載重量(Wmax)の半分以上であるか否かを判定する(ステップW2)。このステップW2において、W≧Wmax/2であると、「乗客がかごの戸2付近にいる」と認識する。また、ステップW2において、W<Wmax/2であると、かごの戸2側の2つのはかり装置11の検出信号から算出された乗客の第1重量(Wf)が、反かごの戸2側の2つのはかり装置11の検出信号から算出された乗客の第2重量(Wr)より大きいか否かを判定する(ステップW3)。このステップW3において、Wf>Wrであると、「乗客がかごの戸2付近にいる」と認識し、Wf≦Wrであると、「乗客がかごの戸2付近にいない」と認識する。
【0013】
ここで、乗客はかご1に乗りこむと、心理的に奥に行こうとする。そこで、かご1内が空いているときには、かご1内の奥側(反かごの戸側)が混み、かごの戸2側が空いている状態となる。そこで、Wf>Wrであれば、乗客がかごの戸2付近におり、Wf≦Wrであれば、乗客がかごの戸2付近からはなれている、と推考される。
また、かご1内が混み始め、W≧Wmax/2となると、乗客は比較的空いているかごの戸2側に乗りこむことになる。そこで、乗客がかごの戸2付近にいる、と推考される。
従って、乗客がかごの戸2付近にいるか否かは、図2に示される判定フローにより間接的に判定できる。
【0014】
ついで、エレベータの制御装置の動作について図3を参照しつつ説明する。
制御盤12は、入力されたはかり装置11の検出信号に基づいて、乗客の重量をモニターしている。
そして、かご1が減速して着床階に近づき、昇降路(図示せず)内の停止直前の所定の位置、例えば戸開動作の開始2秒前(ステップS1)にくると、制御盤12は、図2の判定フローに基づいて、乗客がかごの戸2付近にいるか否かを判定する(ステップS2)。
このステップS2において、乗客がかごの戸2付近にいると判定すると、制御盤12は、アナウンス装置6に格納されているメッセージ、例えば「ドアから離れてください。」のメッセージをスピーカ4から流し(ステップS3)、かごの戸2付近にいる乗客に注意を促す。そして、制御盤12は、かごの戸2が開動作する直前で、再度乗客がかごの戸2付近にいるか否かを判定する(ステップS4、S5)。また、ステップS2において、乗客がかごの戸2付近にいないと判定すると、ステップS4に移行する。
【0015】
ステップS5において、乗客がかごの戸2付近にいないと判定すると、制御盤12は、戸開閉機構3を駆動し、かごの戸2を通常の戸開速度で戸開きする(ステップS6)。
また、ステップS5において、乗客がかごの戸2付近にいると判定すると、制御盤12は、アナウンス装置6に格納されているメッセージ、例えば「ドアが開きます。ご注意ください。」のメッセージをスピーカ4から流し(ステップS7)、かごの戸2付近にいる乗客にかごの戸3が開き始める旨の注意を促すとともに、戸閉状態を継続させる(ステップ8)。そして、一定時間、例えば3秒経過するまで、ステップ5、7、8を繰り返し、乗客がかごの戸2付近から離れるのを待つ(ステップS9)。
乗客が3秒以内にかごの戸2付近から離れると、ステップS6に移る。また、乗客が3秒経ってもかごの戸2付近にとどまっていると、ステップ10に移る。そして、制御盤12は、アナウンス装置6に格納されているブザー音をスピーカ4から流しつつ、戸開閉機構3を駆動し、かごの戸2を通常の戸開速度の半分の戸開速度で戸開きする。
【0016】
このように、この実施の形態1では、かごの戸2の開動作が開始される前に、乗客がかごの戸2付近にいると、メッセージを報知してかごの戸2の開動作の開始の注意を乗客に喚起し、乗客がかごの戸2付近から離れるのを促すとともに、かごの戸2の開動作の開始を遅らす。これにより、乗客の手や指等がかごの戸2と出入口柱との隙間に引き込まれる事故を未然に防止することができる。
また、一定の時間が経過しても、乗客がかごの戸2付近から離れない場合でも、ブザー音を報知してかごの戸2の開動作の開始の注意を乗客に喚起するとともに、戸開速度を遅くしてかごの戸2を開けているので、乗客の手や指等がかごの戸2と出入口柱との隙間に引き込まれる事故を未然に防止することができる。
【0017】
また、この実施の形態1では、安価なはかり装置11を用いて防振ゴム9の弾性変形量を検出し、該はかり装置11の検出信号に基づいて乗客の重量を検出しているので、高価なフロアマットセンサが不要となり、従来構造のかごの床を用いることができ、低コスト化が図られる。
また、防振ゴム9をかごの床7の四隅に配置し、各防振ゴム9の弾性変形量を検出するはかり装置11を設けているので、4つのはかり装置11による防振ゴム9の弾性変形量の検出信号に基づいて算出された乗客の総重量(W)と許容最大積載重量(Wmax)との関係、さらには、かごの戸側の2つの防振ゴム9の弾性変形量の検出信号に基づいて算出された乗客の第1重量(Wf)と反かごの戸側の2つの防振ゴム9の弾性変形量の検出信号に基づいて算出された乗客の第2重量(Wr)との関係から、乗客がかごの戸2付近にいるか否かを間接的に判定することができる。
【0018】
また、制御盤12が、乗客の総重量(W)が規定重量を越えたか否かを判定し、乗客の総重量(W)が規定重量を越えた場合に、ブザー音をスピーカ4から流して乗り過ぎを警報するとともに、戸開閉機構3を制御してかごの戸2の閉鎖を制止するようにすれば、乗客の乗り過ぎによる事故を防止するための安全装置として機能し、この種の既設の安全装置を省略することができる。なお、規定重量は、例えば許容最大積載重量(Wmax)の110%に設定している。
【0019】
【発明の効果】
この発明は、以上のように構成されているので、以下に記載されているような効果を奏する。
【0020】
この発明によれば、かごの床とかご床支持板との間に四隅の位置に介装され、乗客の重量により弾性変形する弾性部材と、上記弾性部材のそれぞれの弾性変形量を検出するはかり装置と、かご内の乗客にメッセージを報知するアナウンス手段と、かごの戸を開閉させる戸開閉機構と、上記かごの戸の開動作前に、上記はかり装置の検出信号に基づいて上記かごの戸付近に乗客がいるか否かを判定し、上記かごの戸付近に乗客がいないと判定した場合には、上記戸開閉機構を動作させて通常の戸開速度で上記かごの戸の開動作を行わせ、上記かごの戸付近に乗客がいると判定した場合には、上記アナウンス手段を動作させて戸開動作の開始を報知して乗客に注意を促すとともに、上記戸開閉機構を動作させて通常の戸開速度より遅い戸開速度で上記かごの戸の開動作を行わせる制御手段とを備えているので、乗客の手や指などがかごの戸の開動作時にかごの戸とかごの出入口柱との隙間に引き込まれることを未然に防止できる安価なエレベータの制御装置が得られる。
【0021】
また、上記制御手段は、上記はかり装置の検出信号に基づいて乗客の総重量を算出し、該乗客の総重量がかごの許容最大搭載重量の1/2以上となった場合に乗客がかごの戸付近にいると判定するので、乗客がかごの戸付近にいるか否かを間接的に検知でき、乗客の重量を直接検出する高価なフロアマットセンサをかごの床の構造を変えてかごの戸付近に設置する必要がない。
【0022】
また、上記制御手段は、かごの戸側の上記はかり装置の検出信号に基づいて乗客の第1重量を算出し、かつ、反かごの戸側の上記はかり装置の検出信号に基づいて乗客の第2重量を算出し、乗客の第1重量>乗客の第2重量となった場合に乗客がかごの戸付近にいると判定するので、乗客がかごの戸付近にいるか否かを間接的に検知でき、乗客の重量を直接検出する高価なフロアマットセンサをかごの床の構造を変えてかごの戸付近に設置する必要がない。
【0023】
また、上記制御手段は、上記はかり装置の検出信号に基づいて乗客の乗りすぎか否かを判定し、乗客の乗りすぎと判定した場合には、上記アナウンス手段を動作させて乗客の乗りすぎを乗客に報知するとともに、上記かごの戸の閉動作を制止するように上記戸開閉機構を制御する機能を備えているので、乗客の乗りすぎを防止するための既設の安全装置を省略することができる。

The floor mat sensor is a floor mat sensor buried in the car floor 7 near the car door 2. The floor mat sensor 10 detects whether a passenger is on the floor mat sensor 10 based on a change in capacitance.
[0003]
In this conventional elevator control apparatus, when the control panel 5 recognizes that the car 1 has landed, it determines whether or not there is a passenger on the floor mat sensor 10 based on a passenger detection signal from the floor mat sensor 10.
When the control panel 5 determines that the passenger is on the floor mat sensor 10, a message stored in the announcement device 6, for example, a message “The door will open. Shed. Thereby, the passenger who was near the car door 2 senses the start of the opening operation of the car door 2 and moves away from the car door 2.

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a schematic diagram illustrating the configuration of an elevator control device according to Embodiment 1 of the present invention, and FIG. 2 is a diagram illustrating the presence or absence of a passenger near a car door in the elevator control device according to Embodiment 1 of the present invention. FIG. 3 is a flowchart illustrating the determination operation, and FIG. 3 is a flowchart illustrating the operation of the elevator control device according to the first embodiment of the present invention.
[0011]
In FIG. 1, 1 is a car, 2 is a car door, 3 is a door opening and closing mechanism for opening and closing the car door 2, 4 is a speaker as an announcement means installed in the car 1, and 6 is a speaker 4 An announcement device as announcement means for storing message contents to be notified to passengers, 7 is a car floor, 8 is a car floor support plate installed below the car floor 7 to support the car floor 7, and 9 is a car floor. Anti-vibration rubber as an elastic member interposed between the car floor 7 and the car floor support plate 8 at the four corners of the floor 7 of the car; A weighing device for detecting the amount of elastic deformation of each of the vibration-isolating rubbers 9 caused by the weight of the passenger; 12 controls the opening and closing operation of the door opening and closing mechanism 3 and announces based on a detection signal of the weighing device 11 The device 6 is controlled so that passengers can receive information via the speaker 4. A control panel as a control means for notifying the message.
[0012]
Next, the operation of the control panel 12 for determining the presence or absence of a passenger near the car door will be described with reference to FIG.
When a passenger gets into the car 1, the rubber cushions 9 arranged at the four corners of the car floor 7 are elastically deformed according to the weight of the passenger. The amount of elastic deformation of the vibration isolation rubber 9 is detected by the scale device 11, and a detection signal is output to the control panel 12.
The control panel 12 receives the detection signals of the respective weighing devices 11, calculates the total weight (W) of the passenger from the four detection signals, and obtains the passenger's first weight from the detection signals of the two weighing devices 11 on the car door 2 side. One weight (Wf) is calculated, and the second weight (Wr) of the passenger is calculated from the detection signals of the two weighing devices 11 on the side of the anti-car door 2 (step w1).
Then, the control panel 12 determines whether or not the total weight (W) of the passenger is equal to or more than half of the allowable maximum load weight (Wmax) of the car 1 (Step W2). In this step W2, if W ≧ Wmax / 2, it is recognized that “the passenger is near the car door 2”. Also, in step W2, if W <Wmax / 2, the first weight (Wf) of the passenger calculated from the detection signals of the two weighing devices 11 on the car door 2 side is equal to the anti-car door 2 side. It is determined whether the weight is larger than the second weight (Wr) of the passenger calculated from the detection signals of the two weighing devices 11 (step W3). In this step W3, if Wf> Wr, it is recognized that “the passenger is near the car door 2”, and if Wf ≦ Wr, it is recognized that “the passenger is not near the car door 2”.
[0013]
Here, when the passenger gets into the car 1, he tries to go to the back psychologically. Therefore, when the inside of the car 1 is vacant, the inside of the car 1 (the door side of the car) is crowded, and the car door 2 side is vacant. Therefore, if Wf> Wr, it is assumed that the passenger is near the car door 2 and if Wf ≦ Wr, the passenger is separated from the vicinity of the car door 2.
Further, when the inside of the car 1 starts to be crowded and W ≧ Wmax / 2, the passenger gets on the relatively empty car door 2 side. Therefore, it is presumed that the passenger is near the car door 2.
Therefore, whether or not the passenger is near the car door 2 can be indirectly determined by the determination flow shown in FIG.
[0014]
Next, the operation of the elevator control device will be described with reference to FIG.
The control panel 12 monitors the weight of the passenger based on the input detection signal of the scale device 11.
When the car 1 decelerates and approaches the landing floor and comes to a predetermined position immediately before the stop in the hoistway (not shown), for example, two seconds before the start of the door opening operation (step S1), the control panel 12 Determines whether the passenger is near the car door 2 based on the determination flow of FIG. 2 (step S2).
If it is determined in step S2 that the passenger is in the vicinity of the car door 2, the control panel 12 sends a message stored in the announcement device 6, for example, a message "please leave the door." Step S3), a passenger in the vicinity of the car door 2 is alerted. Then, immediately before the car door 2 opens, the control panel 12 determines again whether or not the passenger is near the car door 2 (steps S4 and S5). If it is determined in step S2 that the passenger is not near the car door 2, the process proceeds to step S4.
[0015]
If it is determined in step S5 that the passenger is not near the car door 2, the control panel 12 drives the door opening / closing mechanism 3 to open the car door 2 at a normal door opening speed (step S6).
If it is determined in step S5 that the passenger is near the car door 2, the control panel 12 sends a message stored in the announcement device 6, for example, a message "The door opens. Please be careful." From step 4 (step S7), a passenger near the car door 2 is alerted that the car door 3 starts to open, and the door is kept closed (step 8). Then, steps 5, 7, and 8 are repeated until a certain time, for example, 3 seconds, elapses, and waits for the passenger to leave the vicinity of the car door 2 (step S9).
If the passenger leaves the vicinity of the car door 2 within 3 seconds, the process proceeds to step S6. If the passenger stays in the vicinity of the car door 2 even after 3 seconds, the process proceeds to step 10. Then, the control panel 12 drives the door opening / closing mechanism 3 while causing the buzzer sound stored in the announcement device 6 to flow from the speaker 4, and moves the car door 2 at a door opening speed that is half the normal door opening speed. Open.
[0016]
As described above, in the first embodiment, if the passenger is near the car door 2 before the opening operation of the car door 2 is started, the message is notified and the opening operation of the car door 2 is started. Alerts the passenger to move away from the vicinity of the car door 2 and delays the opening operation of the car door 2. Accordingly, it is possible to prevent an accident in which a passenger's hand or finger is drawn into a gap between the car door 2 and the entrance pillar.
Also, even if the passenger does not leave the vicinity of the car door 2 even after a certain period of time, the buzzer is sounded to alert the passenger to start the opening operation of the car door 2 and to open the door. Since the car door 2 is opened at a lower speed, it is possible to prevent an accident in which a passenger's hand or finger is drawn into the gap between the car door 2 and the doorway pillar.
[0017]
Further, in the first embodiment, the amount of elastic deformation of the vibration isolating rubber 9 is detected using the inexpensive weighing device 11 and the weight of the passenger is detected based on the detection signal of the weighing device 11. A simple floor mat sensor is not required, and a car floor having a conventional structure can be used, and cost reduction can be achieved.
Further, since the vibration-proof rubbers 9 are arranged at the four corners of the car floor 7 and the scale devices 11 for detecting the amount of elastic deformation of each of the vibration-proof rubbers 9 are provided. The relationship between the total weight of passengers (W) calculated based on the detection signal of the amount of deformation and the allowable maximum load weight (Wmax), and the detection of the amount of elastic deformation of the two vibration-proof rubbers 9 on the car door side. The first weight (Wf) of the passenger calculated based on the signal, the second weight (Wr) of the passenger calculated based on the detection signal of the amount of elastic deformation of the two vibration-proof rubbers 9 on the door side of the anti-car, and , It can be indirectly determined whether or not the passenger is near the car door 2.
[0018]
Further, the control panel 12 determines whether or not the gross weight (W) of the passenger exceeds a specified weight. When the gross weight (W) of the passenger exceeds the specified weight, a buzzer sounds from the speaker 4. If an alarm is issued for overriding the vehicle and the door opening / closing mechanism 3 is controlled so as to prevent the closing of the car door 2, it functions as a safety device for preventing accidents caused by excessive passengers. Safety device can be omitted. The specified weight is set to, for example, 110% of the allowable maximum load weight (Wmax).

【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0020]
According to the present invention, an elastic member interposed between the car floor and the car floor support plate at four corners and elastically deformed by the weight of a passenger, and a scale for detecting the amount of elastic deformation of each of the elastic members A device, an announcement means for notifying a passenger in the car of a message, a door opening / closing mechanism for opening and closing the car door, and a door of the car based on a detection signal of the weighing device before the opening operation of the car door. It is determined whether or not there are passengers in the vicinity, and if it is determined that there are no passengers in the vicinity of the car door, the door opening / closing mechanism is operated to open the car door at a normal door opening speed. However, if it is determined that there is a passenger near the car door, the announcement means is activated to notify the start of the door opening operation to alert the passenger, and the door opening / closing mechanism is activated to operate normally. Door opening speed slower than the door opening speed Control means for performing the opening operation of the car door is provided, so that the hand or finger of the passenger is drawn into the gap between the car door and the doorway pillar of the car at the time of opening the car door. Thus, an inexpensive elevator control device that can be prevented is obtained.
[0021]
Further, the control means calculates the total weight of the passenger based on the detection signal of the weighing device, and when the total weight of the passenger is equal to or more than の of the allowable maximum mounting weight of the car, the passenger is Since it is determined that the passenger is near the door, it is possible to indirectly detect whether or not the passenger is near the door of the car. There is no need to install nearby.
[0022]
Further, the control means calculates the first weight of the passenger based on the detection signal of the weighing device on the car door side, and calculates the first weight of the passenger based on the detection signal of the weighing device on the anti-car door side. When the first weight of the passenger is greater than the second weight of the passenger, it is determined that the passenger is in the vicinity of the car door. Therefore, it is indirectly detected whether the passenger is in the vicinity of the car door. There is no need to install an expensive floor mat sensor for directly detecting the weight of the passenger near the car door by changing the structure of the car floor.
[0023]
Further, the control means determines whether or not the passenger is too much on the basis of the detection signal of the weighing device.If it is determined that the passenger is too much, the announcement means is operated to prevent the passenger from getting on too much. Since it has a function of notifying passengers and controlling the door opening / closing mechanism so as to stop the closing operation of the car door, it is possible to omit an existing safety device for preventing passengers from getting on too much. it can.
