카메라를 이용한 엘리베이터의 손끼임 방지용 안전장치{SAFETY DEVICE OF ELEVATOR FOR HAND PROTECTION USING CAMERAS}TECHNICAL FIELD [0001] The present invention relates to a safety device for an elevator,

본 발명은 엘리베이터의 손끼임 방지용 안전장치에 관한 것으로, 구체적으로는 카메라를 이용해 엘리베이터 도어와 문틀 사이의 간격으로 사람의 손이 끼일 때 도어의 개폐를 제어하여 손끼임을 방지하는 안전장치에 관한 것이다.More particularly, the present invention relates to a safety device for controlling the opening and closing of a door when a human's hand is caught by an interval between an elevator door and a door frame by using a camera to prevent the accident.

엘리베이터 도어(D)의 원활한 개폐동작을 위해 도어(D)와 문틀(10) 사이에 간격이 존재하고 있는데, 엘리베이터에 탑승하기 위해 승강장에서 대기하는 승객이 손을 도어 표면에 대고 있는 경우 도어(D)가 열리는 것을 인식하지 못하고 손을 도어 표면에 대고있는 상태에서 문틀과 도어 사이의 틈새로 손이 끼어 상해를 입게되는 사고가 흔하게 발생한다. 특히, 어린아이의 경우 주의력이 부족하여 이런 손끼임 안전사고가 발생하는 경우가 많다. There is a gap between the door D and the door frame 10 for smooth opening and closing operations of the elevator door D. When a passenger waiting on the platform stands on the door surface to ride the elevator, ) Is not recognized and the hand is caught by the gap between the door frame and the door while the hand is put on the surface of the door. Especially, a child is often insufficiently attentive to such a hand-held safety accident.

국민안전처가 2016년 2월 19일 발행한 통계자료에 의하면 지난 10년간 총 319건의 안전사고가 발생하여 365명의 사상자가 발생하였고, 이중 사망자는 91명이었다. 이중 손끼임 사고의 경우 3주 이상 치료가 필요한 중대사고는 매년 1건 정도 발생하였으며, 한국소비자원에 신고된 경미한 사고는 '13년 79건, '14년 103건, '15년 92건에 달하였다. 이런 사고를 방지하기 위해 국내 승강기법은 엘리베이터 도어와 문틀 사이의 틈새기준을 종전의 10mm에서 5mm로 강화하기도 하였다.According to the statistics issued by the National Security Agency on February 19, 2016, a total of 319 accidents occurred over the past 10 years, resulting in 365 casualties, of which 91 were deaths. In case of double-handed accident, one serious accident that requires treatment for 3 weeks or more occurred every year. The minor accidents reported to Korea Consumer Agency were 79 cases in '13, 103 cases in '14, and 92 cases in '15 . In order to prevent such accidents, the domestic elevator method reinforced the clearance standard between the elevator door and the door frame from the previous 10mm to 5mm.

이런 문제를 해결하기 위해 열감지 센서를 이용한 종래의 장치가 도 1에 도시되어 있다. A conventional apparatus using a thermal sensor to solve this problem is shown in Fig.

도 2는 본 발명을 보여주는 도면으로서, 2A는 엘리베이터 도어 정면에 승객이 있는 상태의 정면도와 부분확대도, 2B는 도 2A의 측면도와 부분확대도이다.2 is a view showing the present invention, wherein 2A is a front view and a partially enlarged view of a state in which a passenger is present in front of an elevator door, and 2B is a side view and a partial enlarged view of FIG. 2A.

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 in the figure, the camera 20 is installed in the door frame 10 in the middle of left and right side door frames 10 adjacent to the elevator door D, one by one right and left. Each of the left and right cameras 20 forms a narrow and long target graphic TG across 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 door frame edge of the opposite side, so that forming the target graphic is performed in a conventional manner well known in the camera field Detailed description will be omitted.

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 a partial enlarged view of FIGS. 2A and 2B, when a band-shaped target graphic TG formed along the edge 12 of the door frame is covered or broken by a passenger's hand or an external object to cause discontinuity of the target graphic The camera controller 30 senses this. 2B, the target graphic TG is formed along the edge 12 of the door frame 10 and is located at a distance 14 between the door frame 10 and the door D, The discontinuity of the target graphic TG is generated.

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.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 operation is stopped or the opening / closing speed is slowed by the elevator controller EC and the door controller DC, 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.However, the camera 20 may be disposed on any part of the door frame, including the upper door frame, if necessary.

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.Although two cameras, one for each of the left and right sides, have been described as an example, if necessary, only one camera may be installed in the middle of the door frame and the edges of both door frames may be monitored at the same time. It may be possible to prevent the child from being more precise.

또, 문틀의 모서리가 아니라 엘리베이터 출입구의 다른 위치에 표적그래픽을 형성할 수도 있다.It is also possible to form the target graphic at another position of the elevator doorway, not at 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 shows another embodiment of the present invention, in which 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.Generally, the camera 20 is usually covered with a transparent lid 22 to protect it from external impacts and foreign matter. For example, when the target graphic (TG) formed by the camera 20 needs to be set up or modified or the position of the target graphic must be changed, the transparent cover 22 is opened and the connection port 40 is connected to the notebook , A laptop, and a mobile phone, and can perform a necessary setup, a correction operation, and a position change operation while displaying a screen of the camera 20 on a screen of a portable device (such as a notebook) It is possible to easily carry out the necessary work in accordance with. For example, if it is determined that the width of the linear shape of the target graphic TG is too narrow, the notebook can be connected to the connection port 40 and the width of the target graphic can be increased.

도 4는 손끼임 현상이 발생하는 상황을 순서대로 보여주는 평면도이다.Fig. 4 is a plan view showing a situation in which a hand-stuck phenomenon occurs in order.

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. 4A, the target graphic TG is formed on the corner of the opposite door frame by the camera 20, and the hand of the passenger approaches the surface of the door D as shown in FIG. 4B, The target graphic (TG) is cut off by the hand of the passenger, and the camera controller senses this through the camera 20.
