초록

본 논문에서는 현대사회에서 전자기기를 스마트폰의 앱을 통해 쉽게 작동시킬 수 있다는 것에 의해 기존의 키패드로만 제어되는 도어락과는 달리 스마트폰을 이용하여 도어락을 제어할 수 있게 앱 인벤터를 이용하여 앱을 제작하였다. 블루투스 모듈 실험을 통해 장애물이 없을 시 스마트폰과 통신거리가 최대 10m까지 제어가 되었고, 음성인식 실험을 통해 60dB의 소음 시 주파수가 500~1000Hz와 1000~1500Hz에서는 인식률이 각각 85%와 90%로 나왔으며, 80dB 소음 시 500~1000Hz와 1000~1500Hz일 때는 각각 70%와 80%의 인식률을 보였다. 실험 평가 결과를 통해 편의성과 보안성을 향상할 수 있음을 확인할 수 있었다.

In this paper, unlike door locks that are controlled only by the existing keypad because electronic devices can be easily operated through apps on smartphones in modern society, an app was created using app inventory so that door locks can be controlled using smartphones. Through the Bluetooth module experiment, the communication distance with the smartphone was controlled up to 10m when there were no obstacles, and through the voice recognition experiment, the recognition rate was 85% and 90% at 500~1000Hz and 1000~1500Hz, respectively, and 70% and 80% at 80dB noise. Through the results of the experimental evaluation, it was confirmed that convenience and security could be improved.
