Development of Gas Safety Management System for Smart-Home Services
Park, Gyoutae,Lyu, Geunjun,Jo, Youngdo,Gu, Jaheon,Eun, Jongbu,Kim, Hiesik SAGE Publications 2013 International journal of distributed sensor networ Vol.2013 No.-
<P>We propose a system for improving gas safety management through the use of wireless communication modules and intelligent gas safety appliances. Our system configuration consists of an automatic extinguishing system, detectors, a wall-pad, and a microcomputer controlled micom gas meter to monitor gas flow and pressure as well as the occurrence of earthquakes. The automatic fire-extinguishing system checks for both combustible gaseous leaks and monitors the environmental temperature, while the detector array measures smoke and CO gas concentrations. Depending on detected conditions, the micom gas meter cuts off an inner valve and generates a warning, the automatic fire-extinguishing system cuts off an external valve and sprays extinguishing materials, or the sensors generate signals and take further action when smoke or CO is detected. Information on intelligent measures taken by the gas safety appliances and sensors is transmitted to the wall-pad, which in turn relays this as real time data to a server that can be monitored via an external network (BcN) connection to a web or mobile application for the management of gas safety. To validate this smart-home gas management system, we field-tested its suitability for use in Korean apartments under several scenarios.</P>

Recently, we can find news about toxic and combustible gas accident. So, we have to develop gas detector that can measure gas at non-dangerous area and be possible to monitor gas detection at real time. In this paper, we analyze and estimate a gas sensor module and combustible gas detector that is already developed, by using standard gas sample manufactured Korea Gas Safety. We apply result analyzed data from experience for developing next generation combustible gas detector.
