Claims (4)
- 기설정된 주기로 클럭을 발생시키는 클럭생성부;
제1제어기로부터 출력되는 제어 데이터를 저장하는 제1버퍼;
제2제어기로부터 출력되는 제어 데이터를 저장하는 제2버퍼;
상기 제1버퍼에 저장된 상기 제1제어기의 제어데이터의 존재 여부를 확인하는 제1상태감시기;
상기 제2버퍼에 저장된 상기 제2제어기의 제어데이터의 존재 여부를 확인하는 제2상태감시기;
상기 제1버퍼 및 제2버퍼 중 어느 하나에 저장된 제어데이터를 하위모듈로 전송하도록 스위칭하는 스위칭부; 및
상기 제1상태감시기 및 제2상태감시기로부터 각각 출력된 상기 제1 및 제2제어기의 제어데이터의 확인결과로부터 상기 제1제어기 및 제2제어기의 장애 여부를 판단하고, 상기 장애 여부 판단결과에 따라 상기 제1버퍼 및 제2버퍼 중 제어데이터가 존재하는 버퍼 내의 제어데이터를 하위모듈로 출력하도록 상기 스위칭부의 스위칭을 제어하는 제어부를 포함하고,
상기 제1제어기 및 제2제어기는 액티브(active) 상태로 운영되어 상기 클럭생성부에서 발생된 클럭에 따라 각각 동일한 제어데이터를 동시에 출력하고,
상기 제1상태감시기 및 제2상태감시기는 상기 클럭생성부에서 발생된 클럭 중 기설정된 동일한 클럭 주기 동안에 각각 상기 제1버퍼 및 제2버퍼에 저장된 제어데이터의 존재 여부를 확인하되, 상기 동일한 클럭 주기 동안 기설정된 횟수만큼 상기 제1버퍼 및 제2버퍼에 각각 저장된 제어데이터의 존재 여부를 확인하고,
상기 제어부는 상기 기설정된 횟수의 확인시마다 제어데이터가 모두 존재하지 않은 경우에만 상기 제어데이터가 존재하지 않는 버퍼에 대응하는 제어기에 장애가 발생한 것으로 판단하고,
상기 기설정된 횟수는 상기 동일한 클럭 주기 동안 제어데이터의 존재 여부를 확인가능한 횟수인 것을 특징으로 하는 특징으로 하는 이중화 제어 시스템. - 제 1항에 있어서,
상기 제어부는 상기 제1 및 제2 제어기의 제어 데이터의 존재여부 확인결과, 상기 제어 데이터가 상기 제1 및 제2 버퍼 중 어느 하나에만 존재하는 경우 상기 제어 데이터가 존재하는 버퍼로 스위칭되도록 상기 스위칭부를 제어하는 것을 특징으로 하는 이중화 제어 시스템. - 제 1항에 있어서,
상기 제어부는 상기 제1 및 제2 제어기의 제어 데이터의 존재여부 확인결과, 상기 제1 및 제2 버퍼에 모두 제어 데이터가 존재할 경우 상기 제1제어기 및 제2제어기가 모두 정상 작동 상태인 것으로 판단하여 상기 스위칭부의 이전 스위칭 상태를 그대로 유지하도록 하는 것을 특징으로 하는 이중화 제어 시스템. - 삭제
