Description

本発明は、家屋、ビル、工場、倉庫などの建物を含む構造物躯体の窓や出入口などの開口部に設置される開閉体装置及びその開閉制御方法に係り、特に障害物感知装置の感知信号を無線にて送信する開閉体装置及びその開閉制御方法に関する。 The present invention relates to an opening/closing device installed at an opening such as a window or doorway of a structure including a building such as a house, a building, a factory, or a warehouse, and a method for controlling the opening/closing of the same. The present invention relates to an opening/closing body device that transmits wirelessly and a method for controlling opening/closing thereof.

ビル、工場、倉庫などの建物を含む構造物躯体の開口部に設置されたシャッターカーテンやドアなどの開閉体装置には、その開閉動作を電動で行う電動シャッターや電動ドアが使用されることが多い。このように電動で開閉動作を行うものは、近年その動作を遠隔操作によって制御するための無線方式の無線リモコン送信装置を備えるものがある。これは無線方式にすることによって従来行っていた有線による制御が原因の電気的な問題を低減させることが大きい。 Electric shutters and electric doors, which operate electrically to open and close, may be used for opening/closing devices such as shutter curtains and doors installed at openings in structures, including buildings, factories, warehouses, etc. many. In recent years, some devices that perform electrically operated opening/closing operations are equipped with a wireless remote control transmitter for remotely controlling the operations. By adopting a wireless system, this greatly reduces electrical problems caused by conventional wired control.

無線方式は、電波、赤外線、超音波、あるいは、フラッシュ等のいずれかを搬送媒体として、操作信号を送受信して、制御装置に信号を送り、電動シャッターの開閉機を作動させている。シャッターカーテンを電動で作動させるものにおいては、巻き降ろしの際に障害物があると、それと接触してシャッターカーテンに不具合が発生する可能性もある。 In the wireless method, operating signals are transmitted and received using radio waves, infrared rays, ultrasonic waves, flash, or the like as a carrier medium, and the signals are sent to a control device to operate the electric shutter opening/closing device. In the case of a shutter curtain that is operated electrically, if there is an obstacle during winding down, there is a possibility that the shutter curtain will come into contact with it and cause a problem.

このような障害物に対して、一般的にはシャッターの座板部に障害物感知器を設け、何らかの障害物等を感知した場合に、シャッターカーテンの降下を停止させるなど一定の回避動作を行うようにしている。座板部に設けられた障害物感知器からの感知信号を制御装置に送る方法として、有線方式の他に赤外線等の無線方式を用いる場合がある。この無線方式にも上述のような搬送媒体が使用される。 To deal with such obstacles, an obstacle detector is generally installed on the seat plate of the shutter, and when an obstacle is detected, certain avoidance actions such as stopping the descent of the shutter curtain are performed. That's what I do. In addition to a wired method, a wireless method such as infrared rays may be used as a method for sending a sensing signal from an obstacle sensor provided on the seat plate to the control device. This wireless system also uses the carrier medium described above.

障害物感知器からの感知信号を無線方式にて制御装置に送信するものとしては、特許文献1,2に示すものが知られている。
特許文献1に記載のものは、シャッター開閉操作と障害物感知動作のいずれも無線通信で行うようにしたものである。
特許文献2に記載のものは、障害物の感知の送受に無線電波を用い、これを安定して行えるようにしたものである。

2. Description of the Related Art As devices for wirelessly transmitting a sensing signal from an obstacle sensor to a control device, those shown in Patent Documents 1 and 2 are known.
In the device described in Patent Document 1, both the shutter opening/closing operation and the obstacle sensing operation are performed by wireless communication.
The device described in Patent Document 2 uses radio waves to transmit and receive obstacle sensing, and is able to perform this stably.
Japanese Patent Application Publication No. 10-061354 Japanese Patent Application Publication No. 09-317358

特許文献1に記載のものは、障害物感知信号と操作信号を同じ受信装置で受信している。しかしながら、これらは、違法無線やアーク溶接などの強力な電磁波による影響を受け易い。つまり、従来1種類の搬送媒体で信号の受信を行っていたが特許文献1では2種類以上の搬送媒体を用いて信号の受信を行うようにしたものである。
また、特許文献2に記載のものは、障害物感知信号の送信周波数をこの感知信号の送信中に所定の周波数範囲で変化させることによって、感知信号の受信を安定して行えるようにしている。
In the device described in Patent Document 1, the obstacle sensing signal and the operation signal are received by the same receiving device. However, these are susceptible to strong electromagnetic waves such as illegal radio and arc welding. That is, conventionally, signals were received using one type of carrier medium, but in Patent Document 1, signals are received using two or more types of carrier media.
Furthermore, the device described in Patent Document 2 changes the transmission frequency of the obstacle sensing signal within a predetermined frequency range during the transmission of the sensing signal, thereby making it possible to stably receive the sensing signal.

ところで、一旦設置された建物構造物躯体内におけるシャッターカーテンの周辺環境は施工時と実際の稼働時とで変化する場合が多々ある。例えば、シャッターカーテンの近傍に電子機器或いは金属製の家具や事務用品などが設置されてしまった場合、これらの電子機器、家具、事務用品などが障害物感知装置から発せられる信号に干渉して、その送信信号レベルを減衰させてしまう可能性がある。仮に送信信号レベルが減衰してしまった場合には障害物感知装置における感知状態に支障をきたし、シャッターカーテンの開閉動作時における障害物回避動作の誤作動に繋がる可能性もある。 Incidentally, the surrounding environment of the shutter curtain once installed within the framework of a building structure often changes between the time of construction and the time of actual operation. For example, if electronic devices, metal furniture, office supplies, etc. are installed near the shutter curtain, these electronic devices, furniture, office supplies, etc. may interfere with the signal emitted from the obstacle sensing device. There is a possibility that the transmitted signal level will be attenuated. If the transmission signal level were to be attenuated, the sensing state of the obstacle sensing device would be affected, and there is a possibility that the obstacle avoidance operation would malfunction during the opening/closing operation of the shutter curtain.

これに対して特許文献1に記載のものは、電動シャッターの設置空間に操作信号、障害物感知信号以外の飛び交う種々の信号を受信装置が受信してしまった場合には誤動作を発生させてしまう恐れがあるため2種類の搬送媒体(例えば電波と赤外線等)を使用するようにしたものである。また、特許文献2に記載のものは、シャッターカーテンの開閉高さ位置等により環境条件が変化した場合に生じる電波の減衰を防止するものである。
従って、電波無線方式にて送信する障害物感知信号の信頼性を簡易な方法で向上することができていなかったのが現状である。
On the other hand, the device described in Patent Document 1 causes malfunctions if the receiving device receives various signals other than operation signals and obstacle detection signals in the installation space of the electric shutter. Because of this risk, two types of carrier media (for example, radio waves and infrared rays) are used. Further, the device described in Patent Document 2 prevents the attenuation of radio waves that occurs when environmental conditions change due to the opening/closing height position of the shutter curtain, etc.
Therefore, the current situation is that it has not been possible to improve the reliability of obstacle sensing signals transmitted by radio wave wireless technology using a simple method.

一方、障害物感知装置からの感知信号を赤外線や超音波あるいはフラッシュ等を用いて送信するものがある。例えば、無線信号装置と座板スイッチで構成される障害物感知装置は、シャッター降下中に座板が障害物に接触した場合、座板に取り付けた送信機が発信し受光部がそれを受信し、シャッター制御盤を制御して降下中のシャッターを停止させている。
また、シャッターカーテンの最下部に約2cm程度可動する下枠を設け、その下枠の可動による運動エネルギーによって発電し、危険信号を送信するシャッターカーテン最下部へ設置される送信機と、その危険信号を受け取り、天井部へ設置される制御盤へ送る受信機とで構成され、シャッター降下時に人や物が挟まれるとシャッターを停止させることができる障害物感知装置がある。
しかしながら、これらの障害物感知装置の場合、送信機側と受信機側との間に何らかの物体や人体等が介在し、感知知信号又は非感知信号を送信することができない状態が発生する可能性がある。
On the other hand, there are devices that transmit sensing signals from obstacle sensing devices using infrared rays, ultrasonic waves, flashes, or the like. For example, in an obstacle sensing device consisting of a wireless signal device and a seat plate switch, if the seat plate comes into contact with an obstacle while the shutter is lowering, a transmitter attached to the seat plate sends a signal, and a light receiver receives it. , controls the shutter control panel to stop the shutter during descent.
In addition, a lower frame that can move approximately 2 cm is installed at the bottom of the shutter curtain, and a transmitter is installed at the bottom of the shutter curtain that generates electricity from the kinetic energy generated by the movement of the lower frame and transmits a danger signal. There is an obstacle sensing device that can stop the shutter if a person or object is caught in it when the shutter is lowered.
However, in the case of these obstacle sensing devices, there is a possibility that some object or human body may be present between the transmitter side and the receiver side, resulting in a situation where the sensing signal or non-sensing signal cannot be transmitted. There is.

通常、シャッターカーテンが下限停止時は障害物感知状態となっているので、感知信号の送受信が行われ、シャッターの電動閉動作は停止される。また、障害物感知状態にある場合、シャッターの電動閉操作は無効化される。また、障害物感知状態から非感知状態に移行した場合、すなわち下限停止状態からシャッターカーテンが開動作を開始した場合、座板が床面から離れることによって、障害物感知手段は非感知信号を送受信し、電動閉操作を許可状態としている。 Normally, when the shutter curtain is stopped at the lower limit, it is in an obstacle sensing state, so sensing signals are transmitted and received, and the electric closing operation of the shutter is stopped. In addition, when an obstacle is detected, the electric closing operation of the shutter is disabled. In addition, when the obstacle sensing state shifts to the non-sensing state, that is, when the shutter curtain starts opening from the lower limit stop state, the seat plate leaves the floor, and the obstacle sensing means sends and receives the non-sensing signal. The electric closing operation is permitted.

ところが、送信機側と受信機側との間に何らかの物体や人体等が介在して、この非感知信号を送信することができなかった場合、シャッターカーテンの受信機は上限位置に到達しても非感知信号を受信していなかったために、感知状態を継続することとなり、それによって、閉操作を実行しようしても、閉動作を実行することができない状態に陥ることがある。通常、無線リモコン送信装置などには、このような状態を解除するために、特定のスイッチ、例えば停止スイッチを長押し操作することで解除可能に設定されているが、このような解除操作を熟知していない場合に、閉操作を速やかに実行することができないことがあった。 However, if some object or human body intervenes between the transmitter side and the receiver side, and this non-sensing signal cannot be transmitted, the receiver of the shutter curtain will not be able to transmit even if it reaches the upper limit position. Since the non-sensing signal was not received, the sensing state continues, and as a result, even if the closing operation is attempted, the closing operation may not be executed. Normally, wireless remote control transmitters and the like are set so that they can be released by long-pressing a specific switch, such as a stop switch, in order to release such a state. In some cases, the closing operation could not be executed promptly if the

本発明は、上述の点に鑑みてなされたものであり、障害物感知装置から感知信号及び非感知信号を無線方式にて送受信する際に何らかの障害によって非感知信号の送受信ができなかった場合でも、その後の閉操作を実行することのできる開閉体装置及びその開閉制御方法を提供することにある。 The present invention has been made in view of the above-mentioned points, and even if the non-sensing signal cannot be transmitted or received due to some kind of failure when transmitting and receiving the sensing signal and the non-sensing signal from the obstacle sensing device in a wireless manner, An object of the present invention is to provide an opening/closing body device capable of performing subsequent closing operations and a method for controlling opening/closing thereof.

本発明に係る開閉体装置の第1の特徴は、開動作及び閉動作によって開口部を開放及び閉鎖する開閉体手段と、前記開閉体手段の閉鎖側先端部に設けられ、障害物感知時に感知信号を、障害物非感知時に非感知信号を無線方式にて送信する障害物感知手段と、前記障害物感知手段から前記感知信号を受信することによって障害物感知状態となり、前記非感知信号を受信することによって障害物非感知状態となる信号受信手段と、前記信号受信手段の前記障害物感知状態又は前記障害物非感知状態に応じて前記閉動作を制御する制御手段と、前記開閉体手段の開動作によって前記開口部が全開状態となった場合又は前記開動作による開放が所定時間実行された場合に前記信号受信手段を非感知状態に復帰させる復帰手段とを備えたことにある。 A first feature of the opening/closing body device according to the present invention is that the opening/closing body means opens and closes the opening by opening and closing operations, and the opening/closing body means is provided at the closing side tip of the opening/closing body means, and is provided at the closing side tip of the opening/closing body means to detect an obstacle. Obstacle sensing means for transmitting a non-sensing signal by wireless system when no obstacle is sensed; and an obstacle sensing state by receiving the sensing signal from the obstacle sensing means, and receiving the non-sensing signal. a signal receiving means that becomes an obstacle non-sensing state by controlling the signal receiving means; a control means that controls the closing operation according to the obstacle sensing state or the obstacle non-sensing state of the signal receiving means; The present invention further includes a return means for returning the signal receiving means to a non-sensing state when the opening becomes fully open due to the opening operation or when the opening due to the opening operation is performed for a predetermined period of time.

開閉体手段は、ビル、住宅、工場、倉庫等の建物などの構築・構造物における、出入口や窓部、あるいは内部の通路や空間などの開口部などを開閉移動するシャッターカーテンなどの部材で構成される。開閉体手段がシャッターカーテンの場合には、例えば、建物などの開口部の上部に収納され、まぐさなどを介してシャッターカーテンが下降し、開口部を閉鎖する。これ以外にも開閉体手段が開口部の側部に収納され横引き方式で開閉移動したり、開口部の下部に収納され上昇方式で開閉移動したりするものもある。また、開閉体手段には、閉鎖によって開口部を全閉できるものも全閉できないものも含む。 Opening/closing body means consist of members such as shutter curtains that open and close openings such as doorways, windows, internal passages, spaces, etc. in buildings such as buildings, houses, factories, warehouses, etc. be done. When the opening/closing body means is a shutter curtain, it is stored above an opening in a building, for example, and the shutter curtain is lowered through a lintel or the like to close the opening. In addition to this, there are also devices in which the opening/closing body means is housed on the side of the opening and opens and closes in a horizontal pulling manner, or in which the opening/closing body means is housed in the lower part of the opening and opens and closes in a rising manner. Further, the opening/closing body means includes those whose openings can be fully closed by closing and those whose openings cannot be completely closed.

障害物感知手段は、この開閉体手段の閉鎖側先端部に設けられ、開閉体手段と共に移動するものであり、例えば、閉動作中の移動経路上に障害物が存在することを検出する。障害物感知手段は、障害物感知時に感知信号を、障害物非感知時に非感知信号を、無線方式にて開閉体手段の収納ボックス等に設けられた信号受信手段に送信する。信号受信手段は、感知信号を受信することによって障害物感知状態となり、非感知信号を受信することによって障害物非感知状態となる。制御手段は、信号受信手段が障害物感知状態にあるのか、又は障害物非感知状態にあるのかに応じて閉動作を制御している。 The obstacle sensing means is provided at the closing end of the opening/closing body means, moves together with the opening/closing body means, and detects, for example, the presence of an obstacle on the moving path during the closing operation. The obstacle sensing means wirelessly transmits a sensing signal when an obstacle is sensed and a non-sensing signal when an obstacle is not sensed to a signal receiving means provided in a storage box or the like of the opening/closing body means. The signal receiving means enters the obstacle sensing state by receiving the sensing signal, and enters the obstacle non-sensing state by receiving the non-sensing signal. The control means controls the closing operation depending on whether the signal receiving means is in an obstacle sensing state or in an obstacle non-sensing state.

開閉体手段の閉動作中に障害物感知手段が障害物に接触し、感知信号を送信した場合、信号受信手段は障害物感知状態となるので、制御手段は閉動作中の開閉体手段を停止又は回避動作を実行する。
一方、下限停止状態から開閉体手段が開動作を開始すると、座板が床面から離れることによって、障害物感知手段は非感知信号を送信する。このとき、送信機側と受信機側との間に何らかの物体や人体等が介在し、非感知信号を送受信することができない状態が発生した場合、信号受信手段は障害物感知状態を維持し続けることになる。信号受信手段が障害物感知状態にあっても、開閉体手段の開動作を実行することに支障はないが、開閉体手段が一旦全開した場合、信号受信手段が障害物感知状態にあることによって、リモコン装置から閉操作の信号を受信しても、制御手段は閉動作を実行できないことになる。
この発明では、開閉体手段の開動作によって開口部が全開状態となった場合又は開動作による開放が所定時間実行された場合に信号受信手段を非感知状態に復帰させるようにした。これによって、何らかの障害によって非感知信号の送受信を実行することができなかった場合でも、その後の閉動作を実行することができる。
If the obstacle sensing means contacts an obstacle during the closing operation of the opening/closing body means and transmits a sensing signal, the signal receiving means enters the obstacle sensing state, so the control means stops the opening/closing body means during the closing operation. Or take evasive action.
On the other hand, when the opening/closing body means starts an opening operation from the lower limit stop state, the seat plate leaves the floor surface, and the obstacle sensing means transmits a non-sensing signal. At this time, if some object, human body, etc. intervenes between the transmitter side and the receiver side, and a situation occurs where it is impossible to send and receive non-sensing signals, the signal receiving means continues to maintain the obstacle sensing state. It turns out. Even if the signal receiving means is in the obstacle sensing state, there is no problem in executing the opening operation of the opening/closing body means, but once the opening/closing body means is fully opened, the signal receiving means is in the obstacle sensing state. , even if a closing operation signal is received from the remote control device, the control means cannot execute the closing operation.
In this invention, the signal receiving means is returned to the non-sensing state when the opening becomes fully open due to the opening operation of the opening/closing body means or when the opening is performed for a predetermined period of time. As a result, even if the non-sensing signal cannot be transmitted and received due to some kind of failure, the subsequent closing operation can be performed.

本発明に係る開閉体装置の第2の特徴は、前記第1の特徴に記載の開閉体装置において、前記復帰手段は、前記開口部が全開状態となった場合又は前記開動作による開放が所定時間実行された場合、前記感知信号受信手段の電源出力を一旦オフ状態とし、その後にオン状態にすることによって前記非感知状態に復帰させることにある。
これは、信号受信手段を非感知状態に復帰させるために、電源出力を一旦オフとし、その後にオンとするようにしたものである。これによって、信号受信手段は確実に非感知状態に復帰することになる。
A second feature of the opening/closing body device according to the present invention is that in the opening/closing body device according to the first feature, the return means is configured such that when the opening is fully opened or when the opening by the opening operation is If the sensing signal receiving means is executed for a certain period of time, the power output of the sensing signal receiving means is once turned off and then turned on to return to the non-sensing state.
In this method, in order to return the signal receiving means to a non-sensing state, the power output is once turned off and then turned on. This ensures that the signal receiving means returns to the non-sensing state.

本発明に係る開閉制御方法の第1の特徴は、開動作及び閉動作によって開口部を開放及び閉鎖する開閉体手段の閉鎖側先端部に設けられた障害物感知手段から障害物感知時に感知信号を、障害物非感知時に非感知信号をそれぞれ無線方式にて受信し、受信した前記感知信号又は前記非感知信号に応じて障害物感知状態又は障害物非感知状態に設定され、設定された前記障害物感知状態又は前記障害物非感知状態に応じて前記閉動作を制御する開閉制御方法であって、前記開閉体手段の開動作によって前記開口部が全開状態となった場合又は前記開動作による開放が所定時間実行された場合に前記障害物非感知状態に復帰させることにある。
これは、前記開閉体装置の第1の特徴に対応した開閉制御方法の発明である。
The first feature of the opening/closing control method according to the present invention is that when an obstacle is detected, a sensing signal is sent from the obstacle sensing means provided at the closing side tip of the opening/closing body means that opens and closes the opening by opening and closing operations.

This is an invention of an opening/closing control method corresponding to the first feature of the opening/closing body device.

本発明に係る開閉制御方法の第2の特徴は、前記第1の特徴に記載の開閉制御方法において、前記開口部が全開状態となった場合又は前記開動作による開放が所定時間実行された場合、前記感知信号又は前記非感知信号を受信する信号受信手段の電源出力を一旦オフ状態とし、その後にオン状態にすることによって前記障害物非感知状態に復帰させることにある。
これは、前記開閉体装置の第2の特徴に対応した開閉制御方法の発明である。
A second feature of the opening/closing control method according to the present invention is that in the opening/closing control method according to the first feature, when the opening is fully opened or the opening by the opening operation is performed for a predetermined time. The object is to return to the obstacle non-sensing state by temporarily turning off the power output of the signal receiving means for receiving the sensing signal or the non-sensing signal, and then turning it on.
This is an invention of an opening/closing control method corresponding to the second feature of the opening/closing body device.

本発明の開閉体装置及びその開閉制御方法によれば、障害物感知装置から感知信号及び非感知信号を無線方式にて送受信する際に何らかの障害によって非感知信号の送受信ができなかった場合でも、その後の閉操作を実行することができるという効果を奏する。 According to the opening/closing body device and the opening/closing control method thereof of the present invention, even if the non-sensing signal cannot be transmitted or received due to some kind of failure when transmitting/receiving the sensing signal and the non-sensing signal from the obstacle sensing device in a wireless manner, This has the effect that subsequent closing operations can be performed.

感知信号受信機20は、障害物感知器40からの感知信号及び非感知信号を受信する赤外線受光部21を備えている。感知信号受信機20は、障害物感知器40の感知状態又は非感知状態を示す感知信号又は非感知信号を開閉体制御装置17に出力する。開閉体制御装置17は、感知信号受信機20からの感知信号又は非感知信号に対応した制御信号をシャッター駆動回路16に出力する。リモコン操作スイッチ30は、開ボタン、停止ボタン、閉ボタンを備えたシャッター装置専用の無線方式の操作子である。なお、操作スイッチは壁面などに設けられた有線方式の操作子でもよい。 The sensing signal receiver 20 includes an infrared light receiving section 21 that receives sensing signals and non-sensing signals from the obstacle sensor 40. The sensing signal receiver 20 outputs a sensing signal or a non-sensing signal indicating a sensing state or a non-sensing state of the obstacle sensor 40 to the opening/closing body control device 17 . The opening/closing body control device 17 outputs a control signal corresponding to the sensing signal or non-sensing signal from the sensing signal receiver 20 to the shutter drive circuit 16. The remote control switch 30 is a wireless operator dedicated to the shutter device and includes an open button, a stop button, and a close button. Note that the operation switch may be a wired operator provided on a wall or the like.

障害物感知器40は、シャッターカーテン12の座板部に設けられており、赤外線LED方式の送信機で構成されている。障害物感知器40は、座板スイッチのON/OFFに対応して感知信号及び非感知信号を上方のまぐさ部に設置された感知信号受信機20に送信する。 The obstacle sensor 40 is provided on the seat plate of the shutter curtain 12, and is composed of an infrared LED type transmitter. The obstacle sensor 40 transmits a sensing signal and a non-sensing signal to the sensing signal receiver 20 installed in the upper lintel in response to ON/OFF of the seat plate switch.

感知信号受信機20は、赤外線受光部21を介して障害物感知器40からの赤外線の感知信号を受信し、それに応じて開閉体制御装置17にその感知信号を出力して、シャッター駆動回路16を制御してモータ15の回転、すなわちシャッターカーテン12の上昇下降時の制御を実行する。
感知信号の搬送媒体として赤外線を用いているので、障害物感知器40と赤外線受光部21との間に何らかの物体等が介在すると、それによって感知信号及び非感知信号の送受信を実行することができなくなる。なお、障害物感知器40と感知信号受信機20との間の感知信号及び非感知信号の送受信の搬送媒体として電波を用いた場合は、シャッター装置の周辺空間に飛び交っている種々の電波、例えば、違法無線やアーク溶接などの強力な電磁波により、感知信号及び非感知信号の送受信が誤動作してしまう可能性がある。
The sensing signal receiver 20 receives an infrared sensing signal from the obstacle sensor 40 via the infrared light receiving section 21 and outputs the sensing signal to the opening/closing body control device 17 in response to the infrared sensing signal, and outputs the sensing signal to the shutter drive circuit 16. is controlled to control the rotation of the motor 15, that is, the control when the shutter curtain 12 is raised and lowered.
Since infrared rays are used as a carrier medium for the sensing signal, if an object or the like is present between the obstacle sensor 40 and the infrared receiver 21, the sensing signal and the non-sensing signal cannot be transmitted and received. It disappears. Note that when radio waves are used as a carrier medium for transmitting and receiving sensing signals and non-sensing signals between the obstacle sensor 40 and the sensing signal receiver 20, various radio waves flying around the space around the shutter device, e.g. , strong electromagnetic waves from illegal radio or arc welding may cause the transmission and reception of sensing and non-sensing signals to malfunction.

図3は、開閉体制御装置と感知信号受信機と上下限リミットスイッチの接続関係を示すブロック図である。図4は、開閉体制御装置17が実施する図3の非感知状態への復帰処理の詳細を示すフローチャート図である。 FIG. 3 is a block diagram showing the connection relationship between the opening/closing body control device, the sensing signal receiver, and the upper and lower limit switches. FIG. 4 is a flowchart showing details of the process of returning to the non-sensing state shown in FIG. 3, which is executed by the opening/closing body control device 17.

図3において、上限リミットスイッチ151,152は図1に図示していないが、三相交流モータ15の回転位置に応じてオン・オフ状態を維持するものであり、シャッターカーテン12が上限又は下限位置に達すると、上限リミットスイッチ151又は下限リミットスイッチ152の接点が開いて、シャッターカーテン12が上限位置又は下限位置に達したことを示す上限信号又は下限信号を開閉体制御装置17に送信する。開閉体制御装置17は、シャッターカーテン12が上限又は下限位置に達すると、シャッターカーテン12を上限位置又は下限位置で停止させる。 In FIG. 3, upper limit switches 151 and 152, which are not shown in FIG. When the contact point of the upper limit switch 151 or the lower limit switch 152 is opened, an upper limit signal or a lower limit signal indicating that the shutter curtain 12 has reached the upper limit position or the lower limit position is transmitted to the opening/closing body control device 17. When the shutter curtain 12 reaches the upper limit position or the lower limit position, the opening/closing body control device 17 stops the shutter curtain 12 at the upper limit position or the lower limit position.

開閉体制御装置17が実施する感知信号受信機の非感知状態への復帰処理について説明する。
ステップS41では、開閉体制御装置17は、上限リミットスイッチ151から上限信号を入力したか、及び/又は開動作開始後に所定の時間(シャッターカーテン12が全閉状態から全開状態になるまでのおおよその時間)が経過したかを判断し、yesの場合は、次のステップS42に進み、noの場合はリターンする。すなわち、このステップでは、上限信号が入力すると共に所定時間を経過した場合をyesと判定してもよい。また、上限信号が入力した場合だけをyesと判定してもよいし、または所定時間が経過した場合だけをyesと判定してもよい。さらに、上限信号が入力した場合又は所定時間が経過した場合のいずれかの場合をyesと判定してもよい。
The process of returning the sensing signal receiver to the non-sensing state, which is performed by the opening/closing body control device 17, will be described.
In step S41, the opening/closing body control device 17 determines whether the upper limit signal has been input from the upper limit switch 151 and/or for a predetermined period of time (approximate time from when the shutter curtain 12 changes from the fully closed state to the fully open state) after starting the opening operation. It is determined whether the time period) has elapsed, and if YES, the process advances to the next step S42; if NO, the process returns. That is, in this step, the determination may be made as YES if the upper limit signal is input and a predetermined period of time has elapsed. Further, it may be determined as yes only when the upper limit signal is input, or it may be determined as yes only when a predetermined time has elapsed. Furthermore, the determination may be made as YES if either the upper limit signal is input or a predetermined time has elapsed.

ステップS42では、感知信号受信機20への電源出力をオフにする。
ステップS43では、感知信号受信機20への電源出力をオンにする。
すなわち、ステップS42及びステップS43の処理によって、感知信号受信機20の電源が再起動され、感知信号受信機20は非感知状態に復帰し、非感知信号を出力するようになる。なお、ステップS42及びステップS43の非感知状態への復帰処理は、感知信号受信機20が感知状態にあって、感知信号を出力している場合にだけ実行するようにしてもよい。
In step S42, the power output to the sensing signal receiver 20 is turned off.
In step S43, the power output to the sensing signal receiver 20 is turned on.
That is, through the processes of steps S42 and S43, the power of the sensing signal receiver 20 is restarted, the sensing signal receiver 20 returns to a non-sensing state, and outputs a non-sensing signal. Note that the process of returning to the non-sensing state in steps S42 and S43 may be executed only when the sensing signal receiver 20 is in the sensing state and outputting the sensing signal.

この実施の形態によれば、シャッターカーテンが設置された周辺の環境の変化によって障害物感知器40が障害物感知状態から非感知状態に移行しているにも係わらず、感知信号受信機20が感知状態に対応した感知信号を継続させて出力している場合でも、シャッターカーテン12を上限位置に達した場合、又は開動作開始後に所定の時間(シャッターカーテン12が全閉状態から全開状態になるまでのおおよその時間)が経過した場合は、感知信号受信機20を非感知状態に復帰させる。これによって、感知信号受信機20が非感知状態のままであっても、閉操作を実行することができないという状態を回避することが可能である。 According to this embodiment, even though the obstacle sensor 40 is transitioning from an obstacle sensing state to a non-sensing state due to a change in the surrounding environment where the shutter curtain is installed, the sensing signal receiver 20 is Even when the sensing signal corresponding to the sensing state is continuously output, when the shutter curtain 12 reaches the upper limit position or after the start of the opening operation, the shutter curtain 12 changes from the fully closed state to the fully open state. (approximate time) has passed, the sensing signal receiver 20 is returned to the non-sensing state. This makes it possible to avoid a situation in which the closing operation cannot be performed even if the sensing signal receiver 20 remains in the non-sensing state.

上述の実施の形態では、障害物感知器40と感知信号受信機20との間の無線方式の搬送媒体として、赤外線を例に説明したが、電波、超音波、フラッシュ等の搬送媒体を用いてもよい。
上述の実施の形態では、上下昇降方式で繰り出されるシャッターカーテンを例に説明したが、シャッター状の開閉部材が横引き方式で繰り出されたり、あるいは水平方式で繰り出されたりするものであっても同様に適用することができる。また、開閉体装置としては、例えば、シャッター装置、窓シャッター装置、ブラインド装置、ロールスクリーン装置、垂れ幕装置、引戸装置、移動間仕切装置、オーニング装置、防水板装置などにも適用可能である。
In the above embodiment, infrared rays are used as an example of a wireless carrier medium between the obstacle sensor 40 and the sensing signal receiver 20. Good too.
In the above-described embodiment, the shutter curtain that is paid out in an up-and-down manner is explained as an example, but the same applies even if the shutter-like opening/closing member is paid out in a horizontal pulling manner or in a horizontal manner. It can be applied to Further, as the opening/closing body device, for example, it can be applied to a shutter device, a window shutter device, a blind device, a roll screen device, a banner device, a sliding door device, a movable partition device, an awning device, a waterproof board device, etc.
