Abstract

A remote monitoring panel and control system was developed to control various valves and access control chambers, including gas shutoff valves used in CBR(Chemical, Biological and Radiological) facilities. The remote monitoring panel consisted of a main panel installed in the NBC (Nuclear, Biological and Chemical) control room and auxiliary panel installed in the clean room, and the size was divided into pure control and control including CCTV. This system can be monitored and controlled remotely according to the situation where an explosion door and gas barrier door can occur during war and during normal times. This system is divided into normal mode and war mode. In particular, it periodically senses the operation status of various valves, sensors, and filters in the CBR facilities to determine if each apparatus and equipment is in normal operation, and remotely alerts situation workers when repair or replacement is necessary. Damage due to the abnormal operation of each device in the situation can be prevented. This enables control of the blower, supply and exhaust damper, emergency generator, and coolant pump according to the state of shutoff valve and positive pressure valve in the occurrence of NBC, and prevents damage caused by abrupt inflow of conventional weapons and nuclear explosions.

본 논문에서는 화생방 방호시설에 사용되는 가스 차단밸브를 비롯한 각종 밸브 및 출입통제 챔버를 제어할 수 있는 원격 감시패널과 제어시스템을 개발하였다. 원격 감시패널은 화생방 통제실에 설치되는 메인 패널과 청정 기계실에 설치되는 보조 패널로 구성하였으며, 그 크기를 순수 제어용과 CCTV를 포함한 제어용으로 구분하여 개발하였다. 본 시스템은 방폭문 및 가스 차단문이 전시 및 평시에 발생할 수 있는 상황별 상태에 따라 원격 감시 및 제어가 가능하며, 평시모드와 전시모드로 구분하여 각 모드 작동시 추가적인 활성창을 통하여 제어 정보를 표시한다. 특히, 화생방 방호시설 내부의 각종 밸브 및 센서 그리고 각종 여과기의 동작상태를 주기적으로 센싱하여 각각의 기구 및 기기들의 정상동작 여부를 파악하며, 수리 및 교체가 필요할 경우 이를 원격으로 상황 근무자에게 경보함으로써 위급상황에서 각각의 기기들의 동작이상으로 인한 피해를 미연에 방지한다. 이를 통하여 화생방 상황 발생시 차단밸브 및 양압밸브의 상태에 따른 송풍기, 급기 및 배기 댐퍼의 작동, 비상 발전기 및 냉각수 펌프 등의 제어가 가능하여 재래식 무기 및 핵폭발에 의한 폭풍압의 급격한 유입으로 인한 피해를 예방할 수 있다.
