Abstract

Due to the recent development of battery technology, various types of means of transportation such as electric kickboards, Segways, and electric bicycles have emerged, which can be defined as Personal Mobility. In this paper, as the incidence of safety accidents increases due to the increase in the number of users of Personal Mobility, safety helmet devices that strengthen safety capabilities and peripheral recognition functions were studied. In order for the helmet to send a safety signal, Arduino was used as a base to set the value of the sensor according to changes in distance and angle using the ultrasonic sensor to minimize errors and ensure smooth recognition. In addition, a gyro sensor was used to turn on the direction indicator according to each slope. Using a CDS sensor, the LED is designed to turn on when it goes below 150 lux at night. Finally, it is possible to check whether a helmet is worn within 5cm, and when driving at an average speed, the direction indicator light is turned on at 10 degrees, and the LED is turned on at less than 150 lux.

본 논문에서는 Personal Mobility에 사용되는 스마트헬멧의 안전성 보강을 제안한다. 주요 내용은 헬멧이 안전 신호를 보낼 수 있도록 아두이노를 베이스로 사용하여 초음파 센서를 활용한 거리별, 각도별 변화에 따라 센서의 값을 설정하여 오차를 최소화하여 원활한 인식이 되도록 하였다. 또한, 자이로센서를 활용하여 각 기울기에 따른 방향지시등이 점등되도록 하였다. CDS 센서를 이용하여 야간에 150 lux 이하로 내려갈 시 LED가 점등되도록 설계하였다. 최종적으로 5cm 이내에서 헬멧 착용 여부를 확인할 수 있으며, 평균속도 주행 시 10도에서 방향지시등이 점등되며, 150lux 이하에서 LED가 점등됨을 확인하였다.
