Abstract

In this paper, a smart elevator system was studied using real-time object detection technology based on YOLO(You only look once)v5. When an external elevator button is pressed, the YOLOv5 model analyzes the camera video to determine whether there are people waiting, and if it determines that there are no people waiting, the button is automatically canceled. The study introduces an effective method of implementing object detection and communication technology through YOLOv5 and MQTT (Message Queuing Telemetry Transport) used in the Internet of Things. And using this, we implemented a smart elevator system that determines in real time whether there are people waiting. The proposed system can play the role of CCTV (closed-circuit television) while reducing unnecessary power consumption. Therefore, the proposed smart elevator system is expected to contribute to safety and security issues.

본 논문에서는 YOLO(You only look once)v5를 기반으로 한 실시간 객체 검출 기술을 활용하여 스마트 엘리베이터 시스템을 연구하였다. 외부 엘리베이터 버튼이 눌러지면 YOLOv5 모델이 카메라 영상을 분석하여 대기자의 유무를 판별하고, 대기자가 없다고 판별되면 해당 버튼을 자동으로 취소시킨다. 연구에서는 YOLOv5와 사물인터넷에서 활용되는 MQTT(Message Queuing Telemetry Transport)를 통한 객체 탐지 및 통신 기술의 효과적인 구현 방법을 소개한다. 그리고 이를 활용하여 대기자 유무를 실시간으로 판별하는 스마트 엘리베이터 시스템을 구현하였다. 제안한 시스템은 불필요한 소비 전력을 절감하면서 CCTV(closed-circuit television)의 역할을 할 수 있다. 따라서 제안한 스마트 엘리베이터 시스템은 안전 및 치안 문제에도 기여할 수 있을 것으로 기대한다.
