센서 융합형 사용자 친화적 도어 사고 방지 제어 시스템 구현 = Implementation of a User-Friendly Door Safety Control System based on Sensor Fusion

다국어 초록 (Multilingual Abstract)

Entrapment and collision accidents occurring during the opening and closing of doors in the home are serious risks, particularly for children and the elderly. Therefore, this study proposes an intelligent door control system that prevents accidents by integrating real-time detection and assessment of door handle operation, door movement, and other hazards. The proposed system consists of a door handle module consisting of touch, Inertial Measurement Unit (IMU), ultrasonic, and Infrared (IR) sensors, and a control module including actuators and brakes, and each module communicates via Radio Frequency (RF) communication. Experiments verified the stability of inter-sensor communication and the reliability of context-based control. Furthermore, the ultrasonic sensor, when installed at an angle of approximately 50 degrees from the ground, was found to detect infants and low obstacles. The proposed system is implemented as an attachable module, allowing installation without altering the existing door structure and enabling application in a variety of environments.
