가스안전관리 효율향상을 위한 무선 가스안전관리 기기 및 시스템의 구현

The gas safety management system using gas safety apparatuses we proposed is consisted of an intelligent gas meter, a gas leak cut-off instrument, an automatic extinguisher, CO and Smoke sensors. Our system can monitor flow and pressure of gas, earthquake, temperature, CO, smoke and leak of methane in realtime. Then our system take safety measures to protect a serious gas risk by monitoring an abnormal event. And then the gas safety management system communicate with a wall-pad including a gateway by zigbee network in buildings and to report the event to user from the safety management program on a server. Also, the inner cutoff valve of an intelligent gas meter is operated if any event occurred or abnormal at each sensor.
