스마트 글래스의 LED 배치 및 회로 생성을 위한 CAD시스템

Abstract

Industrial companies aim to improve their productivity by using the latest technologies such as Big Data, artificial intelligence, and IoT. However, small and medium-sized companies (SMEs) often lag behind with the introduction of new technologies and refrain from automating their production processes. In this regard, SMEs that produce smart glass, the production of which requires advanced technology, often continue to depend on manual production processes. We analyzed the existing production process to determine whether the integration of CAD technologies could be used to improve the productivity. This study was limited specifically to the development of algorithms for placing the LEDs in the glass in correspondence with the designed shape and to automatically generate a circuit for delivering current to the LEDs. The arrangement of the LEDs is designed to minimize the discrete Fréchet distance in consideration of the “local maximum point of curvature” and “kink point,” and the circuit is automatically organized by grouping a certain number of LEDs to supply similar current to the LEDs. Finally, the time required for LED placement and circuit preparation was reduced from 2 hours to 10 minutes.
