Abstract

In this thesis we introduce a large quantity of input interface system using a low cost single chip microcontroller which is consists of walking board with 1600 switches, RS485 communication for switch data communication and PC application software for walking pattern analysis. When a pedestrian walks on the walking board, the pattern analysis of foot pressed switches can be utilized on diverse divisions of sports and industry such as walking physical therapy, dancing, a large quantity of sensors interface system, etc.

본 논문은 대량의 입력 신호를 받아들이기에 부족한 수십 개의 입출력 포트를 가지는 저가의 8비트 원칩 마이크로 컨트롤러로 키패드 인터페이스 회로와 RS485통신을 이용하여 평면에 25mm의 간격으로 2차원적으로 균일하게 배치된 1600개의 대용량 스위치 입력 신호를 초당 10회의 실시간으로 PC로 읽어 들이고, 얻어진 스위치 정보의 물리적 패턴을 분석한 보행 분석실험의 실례를 들어 스텝분석이나 물리적인 입력의 패턴 분석이 필요한 각종 스포츠, 댄싱, 오락분야 혹은 대량의 스위치 및 센서 입력이 필요한 산업분야 등에 사용되어질 수 있음을 보이고자 한다.
