Management system and method for gas devices and mobile terminal

The invention provides a management system and method for gas devices and a mobile terminal. The system comprises a background server, at least one mobile terminal and two-dimensional code modules onthe gas devices, wherein a two-dimensional code is set in each two-dimensional code module; the mobile terminal is configured to scan the target two-dimensional code in the two-dimensional code moduleon the target gas device, analyze a target identifier of the target gas device from the target two-dimensional code, receive a management operation input by a user and send the management operation and the target identifier to the background server; the background server is configured to store the correspondence between the identifier of at least one gas device and the information of a full lifecycle, determine the information of the full life cycle corresponding to the target identifier according to the correspondence when receiving the management operation and the target identifier sent byany mobile terminal, and ma
