Description

장애물 감지 및 알림 기능이 있는 손전등 {Flashlight with obstacle detection and notification}Flashlight with obstacle detection and notification}

본 고안은 장애물 감지 및 알림 기능이 있는 손전등에 관한 것으로, 더욱 상세하게는 화재 발생 시 정전이나 연기로 인해 기존의 손전등으로 시야확보가 어려울 때 기존의 손전등에 초음파나 적외선 등의 거리 감지 센서를 장착하여 장애물을 감지하고 장애물이 있을 때 버저 음이나 손전등의 밝기 변화로 장애물의 유무와 거리를 알려줌으로써 안전하게 대피할 수 있도록 하는 장애물 감지 및 알림 기능이 있는 손전등에 관한 것이다. The present invention relates to a flashlight with an obstacle detection and notification function, and more specifically, when it is difficult to secure visibility with an existing flashlight due to power outages or smoke in the event of a fire, a distance detection sensor such as ultrasonic or infrared rays is installed on the existing flashlight. The present invention relates to a flashlight with an obstacle detection and notification function that detects an obstacle and informs the presence and distance of an obstacle by a buzzer sound or a change in the brightness of a flashlight when there is an obstacle.

일반적으로 손전등은 전구나 방광다이오드(LED) 등으로 필요한 곳을 비추어 밝게 한다, 거리 감지 센서는 초음파나 적외선을 사용하고 초음파의 경우 초음파를 발생시켜 초음파소자로 송출하고 장애물에서 반사되는 초음파를 감지하여 송출 후 되돌아오는 시간으로 거리를 감지한다. 적외선의 경우 적외선 발광다이오드와 포토TR로 구성하여 적외선 발광다이오드로 적외선을 송출하고 포토TR로 수신되는 적외선의 각도를 검출하여 거리를 감지한다. 장애물 감지 시 전구나 방광다이오드(LED)의 밝기 조절은 펄스폭변조(PWM)방식으로 듀티비(DUTY RATIO)를 조절하면 된다. In general, a flashlight illuminates a necessary place with a light bulb or a bladder diode (LED), etc., and the distance sensor uses ultrasonic waves or infrared rays, and in the case of ultrasonic waves, it generates ultrasonic waves and transmits them to the ultrasonic device and detects ultrasonic waves reflected from obstacles. The distance is detected by the return time after transmission. In the case of infrared, it is composed of an infrared light emitting diode and a photo TR, transmits infrared light to the infrared light emitting diode, and detects the distance by detecting the angle of the infrared ray received by the photo TR. When detecting an obstacle, you can control the brightness of a light bulb or a bladder diode (LED) by adjusting the duty ratio using the pulse width modulation (PWM) method.

건물이나 아파트에서 화재가 발생하면 정전이나 연기로 인해 시야확보가 불가능해 대피에 어려운 문제점이 있었다. If a fire occurs in a building or apartment, it is difficult to evacuate because it is impossible to secure visibility due to power outages or smoke.

손전등에 초음파나 적외선으로 구성된 거리 감지 센서를 장착하여 대피자의 전방에 장애물의 유무와 장애물과 손전등간의 거리를 감지하고 이를 버저를 통하여 소리로 알려주거나 전구나 발광다이오드(LED)의 밝기 조절로 대피하는 사람에게 알려 줄 수 있어 상기의 문제점을 해결 할 수 있다. The flashlight is equipped with an ultrasonic or infrared distance sensor to detect the presence or absence of an obstacle in front of the evacuee and the distance between the obstacle and the flashlight, and notify it by sound through a buzzer or evacuate by adjusting the brightness of a light bulb or light-emitting diode (LED). The above problem can be solved by being able to inform the person who is doing it.

본 고안은 화재 시 연기와 정전으로 인해 시야확보가 불가능한 경우나 야간에 지진 등으로 정전이 되는 경우 전방에 장애물의 유무와 거리를 알고 쉽게 대피할 수 있어 인명 피해를 줄일 수 있다. In the case of a fire, when it is impossible to secure visibility due to smoke and power outages, or when there is a power outage due to an earthquake at night, the present invention can easily evacuate by knowing the presence of obstacles and the distance in front of it, thereby reducing human damage.
