Design of household gas emergency solution based on earthquake early warning and intelligent gateway

At present, the national earthquake intensity quick report and early warning project is in the full implementation stage. In Fujian, the earthquake early warning information can be provided to the public through mobile app and specific terminals. But there is also a lack of effective solutions to use the early warning information to reduce personal and property losses for the majority of family users. Earthquake emergency disposal is the key technology to use the earthquake early warning information to solve the problem in last 1km. The intelligent gateway receives the earthquake early warning information through the message middleware, and processes to evaluate the safety of earthquake gas, then judges whether to start the gas earthquake emergency disposal system. The intelligent gateway communicates with the server through WiFi. and communicates with gas earthquake emergency disposal system through ZigBee wireless communication technologies, and realizes the automatic shutdown of gas when destructive earthquake occurrence. The system can prevent the occurrence of gas accidents in destructive earthquakes, make full use of earthquake early warning information, realize the home application of earthquake early warning information, and reduce casualties and economic losses caused by earthquakes.
