A positive study on effective gas safety management using wireless sensor network

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.
