Abstract:

In order to solve the problems of "smart fire" construction, such as the types of hardware accessed in the sensing layer are limited, accessing technology is poor, the application of NB- IoT in "smart fire" construction is discussed. A 3- layer model of "smart fire" construction is proposed. The NB-IoT terminal is acquisition layer. The public IoT, big data, cloud computing, blockchain and artificial intelligence are network layer. The fire risk judgement, information management of fire supervision, independent management of social units, digital management of fire facilities and intelligent firefighting and rescue are application layer. The model can improve the modernization, informationization and intellectualization of social fire safety management.  

Key words: NB- IoT, smart fire, fire management, firefighting and rescue
