In this paper, we developed and positively tested the effective gas safety management system using wireless intelligent gas safety appliances to monitor gas flow and pressure, earthquake in a micom-gas-meter, to check combustible gas leaks and temperature (upper 100°C) in an automatic extinguisher and to detect smoke and CO gases. Then our system take safety measures such as cutoff, warning and messaging to protect a serious risk if results of event are abnormal, communicate with a wall-pad including a gateway with Jennic ZigBee network in buildings and inform those risky events to user via the safety management program in our web server. Also, the built-in every inner cutoff valve in intelligent gas meters and the middle valves in automatic extinguishers are operated automatically if irregular events are occurred and signal to the controlling wall-pads to a managing server.
