도 2는 본 발명을 보여주는 도면으로서, 2A는 엘리베이터 도어 정면에 승객이 있는 상태의 정면도와 부분확대도, 2B는 도 2A의 측면도와 부분확대도이다.Figure 2 is a view showing the present invention, 2A is a front view and a partially enlarged view of the passengers in front of the elevator door, 2B is a side view and a partially enlarged view of FIG.
도시된 바와 같이, 엘리베이터 도어(D)에 인접한 좌우측 측면 문틀(10)의 중간에 좌우 1대씩 카메라(20)가 문틀(10)에 매립되게 설치된다. 좌우 카메라(20) 각각이 맞은편 측면 문틀(10)의 모서리(12)를 따라 문틀(10)의 전장에 걸쳐 좁고 기다란 표적그래픽(TG)을 형성한다. 도 2A에 도시된 것처럼, 카메라(20)의 시야각을 조절하여 맞은편 문틀 모서리의 전장에 걸쳐 표적그래픽(TG)을 형성하도록 하는데, 이렇게 표적그래픽을 형성하는 것은 카메라 분야에 널리 알려진 기존의 방식으로 가능하므로 자세한 설명은 생략한다. As shown, the cameras 20 are installed in the door frame 10 one by one in the middle of the left and right side door frame 10 adjacent to the elevator door (D). Each of the left and right cameras 20 forms a narrow and long target graphic TG over the entire length of the door frame 10 along the edge 12 of the opposite side door frame 10. As shown in FIG. 2A, the viewing angle of the camera 20 is adjusted to form a target graphic TG over the entire length of the opposite door frame edge, which is a conventional method well known in the field of cameras. Detailed description is omitted since it is possible.
도 2A와 2B의 부분확대도에 자세히 표시된 것처럼, 문틀의 모서리(12)를 따라 형성되는 띠 모양의 표적그래픽(TG)이 승객의 손이나 외부 물체에 의해 가리거나 끊어져 표적그래픽의 불연속성이 생기면 (후술하는) 카메라 컨트롤러(30)가 이를 감지한다. 도 2B의 부분확대도에서 알 수 있듯이, 표적그래픽(TG)은 문틀(10)의 모서리(12)를 따라 형성되고, 문틀(10)와 도어(D) 사이의 간격(14)에 승객의 손이 끼이게 되면 표적그래픽(TG)의 불연속성이 생기게 된다. As shown in detail in the partially enlarged views of FIGS. 2A and 2B, if the band-shaped target graphic TG formed along the edge 12 of the door frame is covered or broken by the passenger's hand or an external object, the discontinuity of the target graphic occurs ( Camera controller 30 (to be described later) detects this. As can be seen in the partial enlarged view of FIG. 2B, the target graphic TG is formed along the edge 12 of the door frame 10, and the passenger's hand is placed in the gap 14 between the door frame 10 and the door D. This pinch creates discontinuity in the target graphic TG.
도 2A에서 알 수 있듯이, 좌우 카메라(20)는 카메라 컨트롤러(30)에 연결되고, 카메라 컨트롤러(30)에 엘리베이터 컨트롤러(EC)와 도어컨트롤러(DC)가 연결된다. 전술한 바와 같이, 표적그래픽(TG)의 불연속성을 카메라 컨트롤러(30)가 감지하면, 엘리베이터 컨트롤러(EC)와 도어컨트롤러(DC)에 의해 도어작동이 정지되거나 개폐속도가 늦춰짐으로써, 손끼임 사고를 미연에 방지할 수 있다.As can be seen in FIG. 2A, the left and right cameras 20 are connected to the camera controller 30, and the elevator controller EC and the door controller DC are connected to the camera controller 30. As described above, when the camera controller 30 detects the discontinuity of the target graphic TG, the door controller is stopped by the elevator controller EC and the door controller DC, or the opening / closing speed is slowed, thereby causing a hand-caught accident. Can be prevented in advance.
한편, 이런 좌우 카메라(20)를 양쪽 측면 문틀(10)의 중간에 설치한 것을 예로 들어 설명하였지만, 필요에 따라 카메라(20)를 상단 문틀을 포함해 문틀의 어떤 부분에도 배치할 수 있다.On the other hand, the left and right camera 20 has been described as an example installed in the middle of both side door frame 10, the camera 20 can be arranged in any part of the door frame, including the upper door frame as needed.
또, 좌우측 각각에 1대씩 2대의 카메라를 예로 들어 설명하였지만, 필요에 따라서는 카메라를 문틀 중간에 1대만 설치하고 양쪽 문틀의 모서리를 동시에 감시할 수도 있고, 또한 문틀의 적절한 위치에 3대 이상의 카메라를 설치하여 좀더 정밀하게 손끼임을 방지할 수도 있을 것이다.In addition, although two cameras, one on each of the left and right sides have been described as examples, only one camera may be installed in the middle of the door frame, and the edges of both door frames may be simultaneously monitored, and three or more cameras may be placed at an appropriate position of the door frame. You can also install a more precise prevention of hand pinching.
또, 문틀의 모서리가 아니라 엘리베이터 출입구의 다른 위치에 표적그래픽을 형성할 수도 있다.In addition, the target graphic may be formed at another position of the elevator doorway instead of the edge of the door frame.
도 3은 본 발명의 다른 실시예를 보여주는 일례로서, 카메라컨트롤러(30)에 연결되는 별도의 연결포트(40)가 문틀(10)에 설치된 것을 보여준다. 3 is an example showing another embodiment of the present invention, shows that a separate connection port 40 connected to the camera controller 30 is installed in the door frame 10.
일반적으로 카메라(20)는 외부의 충격과 이물질로부터 보호하기 위해 투명덮개(22)로 덮이는 것이 보통이다. 예컨대, 카메라(20)가 형성하는 표적그래픽(TG)을 셋업하거나 수정해야할 경우 또는 표적그래픽의 위치를 변경해야할 경우, 투명덮개(22)를 열고 연결포트(40)에 USB 연결장치 등을 통해 노트북, 랩탑, 휴대전화기를 포함한 각종 휴대기기를 연결하고, (노트북과 같은) 휴대기기의 화면에 카메라(20)의 화면을 디스플레이한채 필요한 셋업, 수정작업 및 위치변경작업을 할 수 있으므로, 사용자의 편의성에 맞춰 필요한 작업을 쉽게 할 수 있다. 예를 들면, 표적그래픽(TG)의 직선모양의 폭이 너무 좁다고 판단되면, 연결포트(40)에 노트북을 연결하고 표적그래픽의 폭을 증가시킬 수 있다.In general, the camera 20 is usually covered with a transparent cover 22 to protect from external impact and foreign matter. For example, when setting up or modifying the target graphic TG formed by the camera 20 or when the position of the target graphic needs to be changed, open the transparent cover 22 and connect the laptop to the connection port 40 through a USB connection device or the like. Users can connect various mobile devices including laptops, mobile phones, and perform necessary setup, modification and repositioning while displaying the screen of the camera 20 on the screen of the mobile device (such as a laptop). You can easily do the necessary work. For example, if it is determined that the width of the straight line of the target graphic TG is too narrow, it is possible to connect the notebook to the connection port 40 and increase the width of the target graphic.
도 4는 손끼임 현상이 발생하는 상황을 순서대로 보여주는 평면도이다.4 is a plan view sequentially showing a situation in which the pinch phenomenon occurs.
도 4A와 같이, 카메라(20)에 의해 반대쪽 문틀 모서리에 표적그래픽(TG)이 형성되고, 도 4B와 같이 도어(D) 표면을 향해 승객의 손이 다가가서, 도 4C와 같이 승객의 손이 도어 표면에 닿으면 승객의 손에 의해 표적그래픽(TG)이 끊어지게 되고, 카메라(20)를 통해 카메라컨트롤러가 이를 감지한다. As shown in Fig. 4A, the target graphic TG is formed at the edge of the opposite door frame by the camera 20, and the passenger's hand approaches the surface of the door D as shown in Fig. 4B.
