Abstract |
In this paper, we developed and tested the effective gas safety management system by 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 measure smoke and CO gas. Then our system takes safety measures such as cutoff, warning and messages to protect a serious risk if results of event are abnormal, communicates with a wall-pad including a gateway with ZigBee network in buildings and to inform the event to user via the safety management program in our server. Also, the inner cutoff valve of intelligent gas meters and automatic extinguishers are operated automatically if irregular events are occurred. |
