In this paper, we proposed a system and a scenario to raise efficiency of gas safety management by developing wireless ZigBee communication modules, smart-home gas safety appliances and the system suitable for gas safety. Our designed system consists of a micom gas meter, an automatic extinguisher, sensors, and a wall-pad. A micom-gas-meter monitors gas flow, gas pressure, and earthquake. An automatic fire extinguisher checks combustible gas leaks and temperature of $100^{\circ}C$(cut off) and $130^{\circ}C$(fire). Sensors measure smoke and CO gas. In our novel system, a micom-gas meter cut off inner valve with warnings, an automatic fire extinguisher cut off middle valve and spray extinguishing materials, and sensors generate signals when detecting smoke and CO and then take a next action. Gas safety appliances and sensors automatically takes measures, and transmit those information to a wall-pad. The wall-pad again transmits real time information to server. Users can check and manage gas safety situations by connecting BcN server through web or mobile application. We hereby devised scenarios for gas safety and risk management based on the smart, and demonstrated their efficiency through test applied to filed.

Although the rate of city gas supply in South Korea has grown significantly, the fields related to gas meters have not yet escaped from the initial method of service (e.g. measurement, safety checks, billing, etc). As smart gas meters are actively developed and researched, the introduction of smart gas meters requires rational performance evaluation methods and standards to verify reliability and safety. The purpose of this paper is to make a prototype of the performance evaluation to test the performance of the smart gas meter and to derive the performance evaluation method by conducting the demonstration operation so that the smart gas meter can be smoothly distributed in South Korea.
