초록

건물에 설치된 엘리베이터는 승강기 호출 버튼과 목적층으로의 선택을 위한 입력 버튼으로 구성되어 있다. 엘리베이터 버튼은 승강기를 이용하는 사람이 직접 눌러야 입력이 된다. 이러한 승객의 입력은 버튼의 오염으로 인해 전염병에 감염될 수 있다. 이러한 문제점을 해결하기 위한 수단으로 비접촉식 버튼이 요구되고, 이는 정전용량 방식을 적용하여 물체의 근접을 감지한다. 적외선 열감지 센서를 부착하여 인체의 체온을 측정하는 기능을 구현하고 UV-LED를 부착하여 버튼의 살균 기능을 제공한다. 물체가 없을 때의 출력파형을 측정하고 물체가 근접할 때의 출력 파형을 측정하여 버튼이 선택되고 적외선온도측정 센서를 통해 체온이 측정되며, 사용자가 없을 때 UV-LED를 점등하여 살균하였다. 비접촉식 엘리베이터 버튼은 전염병을 옮기는 바이러스의 감염을 방지할 수 있는 효과가 있고, 체온을 감지하여 CIVID 19의 양성 확진자를 선별할 수 있어 감염병 예방에도 효과가 있을 것으로 기대된다.

The elevator installed in the building consists of an elevator call button and an input button for selection to the target floor. The elevator button is input only when the elevator user directly presses it. Such passenger input can be infected with an infectious disease due to contamination of the button. A non-contact button is required as a means for solving this problem, which detects the proximity of an object by applying a capacitive method. It implements a function of measuring the body's body temperature by attaching an infrared heat sensor, and provides a sterilization function of a button by attaching a UV-LED. A button was selected, a body temperature was measured through an infrared temperature measurement sensor, and UV-LED was turned on and sterilized when there was no user. The contactless elevator button is expected to be effective in preventing infectious diseases as it can prevent infection of viruses carrying infectious diseases and can detect body temperature to select positive patients of CIVID 19.
