Abstract

The valve device is installed in hazardous areas, such as a chemical plant explosion has been sealed with fire protection device to prevent the risk of explosion. In this paper, due to the explosion-proof devices using external power the device can not be used in infrared sensors and Zigbee sensor valve device by measuring the open degree of valve opening and closing of the danger zone to check whether. Valve opening and closing operation log screen time, we propose a low-power operation monitoring system administrators to manage and control the plant. Develop power control relay board apply an improved algorithm to apply the asynchronous LPL power management. The plant monitoring system and explosion-proof valve opening and closing the valve system with the intelligent device designed and implemented and tested it.

화학공장과 같이 위험지역에 설치된 밸브장치는 폭발의 위험을 방지하기 위해 방화 방폭장치로 밀폐되어 있다. 본 논문에서는 방폭장치로 인해 외부전원장치를 사용할 수 없는 밸브장치에 적외선센서와 Zigbee 센서를 이용하여 위험지역의 밸브의 열림도를 측정하여 개폐여부를 확인하고, 밸브 개폐 작동시간을 로그화하여 운전 관리자가 공장을 관리 통제할 수 있는 저전력 모니터링 시스템을 제안한다. 전력관리기능을 적용하기 위해 개선된 비동기LPL 알고리즘을 적용한 전력제어 릴레이보드를 개발하고, 이를 적용한 방폭형 지능형 밸브시스템과 공장 밸브 개폐모니터링 시스템을 설계하고 이를 구현 및 테스트 하였다.
