건물 내 무선 ZigBee 통신을 이용한 가스안전관리 향상 연구

The gas safety management system using an intelligent gas meter we proposed is to monitor flow and pressure of gas, earthquake, temperature, smoke and leak of methane in realtime. Then our system takes safety measures to protect a serious gas risk by monitoring an abnormal event from gas safety management system, to 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 in a server. Also, the inner cutoff valve of an intelligent gas meter is operated if any event occurred or abnormal at each sensor.
