従来の技術
人が踏むことで検知信号を出力するマツトスイ
ツチ、
投光器より発射した光が人体に当つて反射した
ことを受光器で受光し、その受光器より検知信号
を出力するようにした光電式検知装置、等が知ら
れている。Conventional technology Matsuto switch outputs a detection signal when a person steps on it, and photoelectric detection uses light emitted from a projector that hits the human body and is reflected by a receiver, which then outputs a detection signal. devices, etc. are known.
考案が解決しようとする問題点
人が扉の近くを通過すると検知信号を出力し、
扉が開閉動作するので、扉を通過する意志のない
人が扉の近くを歩行した時にも開閉動作するから
無駄である。Problems that the invention aims to solve: When a person passes near the door, a detection signal is output,
Since the door opens and closes, even when a person who does not intend to pass through the door walks near the door, the door opens and closes, which is wasteful.
人の歩行速度を検知したり、人の幅を検知した
りするには、複数のマツトスイツチや投・受光器

ら、配線作業や取付作業が面倒となつてしまう。 To detect a person's walking speed or the width of the person, multiple Matsuto switches or emitters/receivers can be installed in parallel in the direction of travel of the person, or in a direction perpendicular to the direction of travel. It is necessary to input the detection signal into the detection circuit and detect the walking speed of the person and the width of the person based on the detection signal, and it is necessary to connect each matsuto switch and each emitter/receiver to the detection circuit. Wiring and installation work become troublesome.

Based on this signal, the door is connected to a control circuit that outputs a human body detection signal, allowing the door to open and close only when a person passes through the door, depending on the person's walking speed and width.
実施例
第１図は自動扉の取付状態を示す概略断面図で
あり、天井１と床２とに亘つて自動扉３が取付け
られ、この自動扉３はドア枠４に扉５を開閉自在
に設けてある。Embodiment FIG. 1 is a schematic sectional view showing how an automatic door is installed. An automatic door 3 is installed across a ceiling 1 and a floor 2, and a door 5 is attached to a door frame 4 so that it can be opened and closed. It is provided.
天井１における自動扉３の両側位置にはイメー
ジセンサ６がそれぞれ配設され、各イメージセン
サ６の視野はレンズ７でそれぞれ拡大されて床２
の広範囲な部分２ａ，２ａを検知可能としてあ
る。 Image sensors 6 are disposed on both sides of the automatic door 3 on the ceiling 1, and the field of view of each image sensor 6 is enlarged by a lens 7 to
It is possible to detect a wide range of parts 2a, 2a.
前記イメージセンサ６は光学情報を電気信号に
変換するもので、第２図に示すように多数の画素
８を縦・横方向に複数配設したものであり、各画
素８には縦（扉５に向う方向）・横（扉５と平行
な方向）の符号１〜６，１０〜９０が符されて検
知範囲を番地づけできるようにしてある。 The image sensor 6 converts optical information into electrical signals, and has a large number of pixels 8 arranged vertically and horizontally as shown in FIG. 1 to 6 and 10 to 90 in the direction toward the door) and the side (in the direction parallel to the door 5), so that the detection range can be numbered.
なお、画素８としては撮像管、フオト・ダイオ
ードなどの固体撮像素子が用いられ、検知範囲に
人が侵入すると信号を出力するようにしてある。 Note that a solid-state image sensor such as an image pickup tube or a photo diode is used as the pixel 8, and a signal is output when a person enters the detection range.
前記各イメージセンサ６よりの信号は制御回路
９に入力されて人の歩行速度や人の幅等を検知で
きるようにしてある。 Signals from each of the image sensors 6 are input to a control circuit 9 so that the walking speed of the person, the width of the person, etc. can be detected.
しかして、人Ａが矢印方向イに扉５に向けて歩
いてくると、横５番目で縦１番目（51）の画素８
より縦２，３，４，５，６番目（52）（53）（54）
（55）（56）の画素８が順次信号を出力するから、
制御回路９は人Ａが扉５に向けて歩いて来たこと
を検知して制御回路９より人体検知信号を扉開閉
動作制御回路に出力して扉５を開閉動作する。 However, when person A walks toward door 5 in the direction of arrow A, pixel 8, which is the fifth horizontally and first vertically (51),
Vertical 2nd, 3rd, 4th, 5th, 6th (52) (53) (54)
Since pixels 8 of (55) and (56) output signals sequentially,
The control circuit 9 detects that the person A is walking towards the door 5, and outputs a human body detection signal from the control circuit 9 to the door opening/closing operation control circuit to open/close the door 5.
この時、縦方向の画素８より順次出力される信
号の出力速度によつて人Ａの歩行速度を検知で
き、その歩行速度に応じて制御回路９より扉５の
開閉速度を決定する信号を出力する。 At this time, the walking speed of person A can be detected based on the output speed of the signals sequentially output from the vertical pixels 8, and according to the walking speed, the control circuit 9 outputs a signal that determines the opening/closing speed of the door 5. do.
例えば、人Ａが扉５に向けて速く歩いた時には
縦方向の画素８より順次出力される信号の出力速
度が早くなり、それによつて制御回路９は歩行速
度が速いと判断して扉５を速く開閉動作すべく信
号を出力し、人Ａが扉５に向けて遅く歩いた時に
は前述の信号の出力速度が遅くなり、それによつ
て制御回路９は歩行速度が遅いと判断して扉５を
遅く開閉動作すべく信号を出力する。 For example, when person A walks quickly toward the door 5, the output speed of the signals sequentially output from the vertical pixels 8 becomes faster, and the control circuit 9 determines that the person A is walking faster and walks toward the door 5. A signal is outputted to open and close the door quickly, and when the person A walks slowly toward the door 5, the output speed of the aforementioned signal becomes slow, and the control circuit 9 determines that the walking speed is slow and closes the door 5. Outputs a signal to open/close slowly.
また、信号を出力する横方向の画素８の数によ
つて制御回路９は人の幅、つまり体格や人数を検
知判断し、それによつて扉５の開き幅寸法を出力
する。 Further, the control circuit 9 detects and determines the width of the person, that is, the physique and number of people, based on the number of pixels 8 in the horizontal direction that output signals, and outputs the opening width dimension of the door 5 accordingly.
また、人Ａが矢印方向ロに歩行する場合、つま
り、扉５を通過せずに扉５に接近して歩行する場
合には縦２番目（２）で横方向10，20，30，40，
50，60，70，80，90番目の画素８が順次信号を出
力し、それによつて制御回路９は人Ａが扉５を通
過する意志なしに扉５に接近して歩行したことを
検知して、制御回路９は人体検知信号を出力しな
い。これにより無駄に扉５が開閉動作することを
未然に防止できる。 In addition, when person A walks in the direction of the arrow B, that is, when approaching the door 5 without passing through the door 5, the second position in the vertical direction (2) is 10, 20, 30, 40 in the horizontal direction.
The 50th, 60th, 70th, 80th, and 90th pixels 8 sequentially output signals, whereby the control circuit 9 detects that person A has approached door 5 and walked without intending to pass through door 5. Therefore, the control circuit 9 does not output a human body detection signal. This can prevent the door 5 from opening/closing unnecessarily.
また、扉５を通過した人Ａが扉５より遠ざかる
場合には縦方向６，５，４，３，２，１番目の画
素８が順次信号を出力するから、それによつて制
御回路９は扉５を人が通過したことを検知し、扉
閉じ信号を出力する。 Furthermore, when the person A who has passed through the door 5 moves away from the door 5, the pixels 8 in the vertical direction 6, 5, 4, 3, 2, and 1 sequentially output signals. It detects when a person passes through 5 and outputs a door close signal.
また、各画素８と対向する床２の広範囲の部分
２ａ、つまりイメージセンサ６の検知領域内に人
が静止した場合には、信号を出力する画素８が変
化しないので、それによつて制御回路９が人が扉
５の前方で静止したことを検知できる。 Furthermore, when a person stands still within a wide area 2a of the floor 2 facing each pixel 8, that is, within the detection area of the image sensor 6, the pixels 8 that output signals do not change, so that the control circuit 9 can detect that a person has stopped in front of the door 5.
つまり、制御回路９は、イメージセンサ６の各
画素８より出力される信号を受けて、扉５に向う
方向の画素８より順次出力される信号出力速度に
よつて人の歩行速度を検出する機能と、扉５と平

平行なる方向の画素８より順次出力される信号よ
つて扉５を通過せずに扉５に接近して歩行する人
を検出する機能と、信号を出力する画素８が変化
しないことよつて扉５の前方で人が静止した機能
を有する。 In other words, the control circuit 9 has a function of receiving signals output from each pixel 8 of the image sensor 6 and detecting a person's walking speed based on the signal output speed sequentially output from the pixels 8 in the direction toward the door 5. , a function to detect the width of a person by the number of pixels 8 that output signals in the direction parallel to the door 5, and a function to detect the width of a person by the number of pixels 8 outputting signals in the direction parallel to the door 5; It has a function of detecting a person walking approaching the door 5 without passing through the door 5, and a function of detecting a person standing still in front of the door 5 because the pixel 8 that outputs the signal does not change.
イメージセンサ６の各画素８よりの信号によつ
て、人が扉５に接近して歩いて来た場合には扉開
信号、扉から遠ざかる場合には扉閉信号を出力し
て扉５を自動的に開閉できるし、扉開信号を出力
する場合には歩行速度、人の幅に応じて扉開閉速
度、扉開き幅寸法を設定して人が扉５を通過する
時には人の歩行速度や人の幅に応じて扉を開閉で
きる。
Based on the signals from each pixel 8 of the image sensor 6, when a person approaches the door 5, a door open signal is output, and when a person walks away from the door, a door close signal is output, and the door 5 is automatically opened. When a door open signal is output, the door opening/closing speed is set according to the walking speed, the door opening/closing speed is set according to the width of the person, and the door opening width dimension is set according to the walking speed of the person and the person when the person passes through the door 5. The door can be opened and closed depending on the width of the door.
また、人が扉５と平行な方向に歩行する場合に
は扉閉信号を出力しないから扉の無駄な開閉を行
なうことがない。 Further, when a person walks in a direction parallel to the door 5, the door close signal is not outputted, so the door is not opened or closed in vain.
また、イメージセンサ６と制御回路９とを接続
すれば良いから、配線作業や取付作業が簡単とな
る。 Further, since it is only necessary to connect the image sensor 6 and the control circuit 9, wiring work and installation work become easy.
