Abstract

본 발명에서 제안하고 있는 양방향 무선통신을 이용한 시각 동기 시스템에 따르면, 마스터 시각 송수신 장치 및 슬레이브 시각 송수신 장치가 양방향 무선통신으로 정보를 교환하도록 하고 실시간 통합 관리를 위한 망 관리 장치 및 모니터링 장치를 포함함으로써, 시스템에 장애가 발생한 경우 이를 신속히 발견할 수 있도록 하여 사용자의 관리 비용을 절감시키고 효율을 극대화시킬 수 있을 뿐만 아니라, 원거리 환경에도 간단히 중계기만을 설치하여 설비구축 범위의 확장이 용이토록 하고, 정보의 이력 관리를 통해 각종 사건의 증거자료로도 활용할 수 있는 장점이 있다.
