Abstract: In view of the shortcomings of traditional automatic sprinkler system, such as long fire response time and passive activated,as well as the need to adapt to the development of fire Internet of things,based on big data, cloud computing and Internet of Things technology, a research scheme of intelligent automatic sprinkler system software was proposed. The traditional passive sprinkler system is upgraded to an smart automatic sprinkler system, which can realize remote monitoring and precise positioning of sprinkler status, activate group of sprinklers and early fire extinguishing.The system does not require personnel to be on duty 24 hours a day. The management personnel can carry out daily surveillance on the system and spray water in the early stage through terminals such as mobile phones, computers and tablets.Through the full-size fire test, the linkage applicatio performance of the system is verified, and the technical parameters obtained provide a reference for the engineering application of the system.

Key words: automatic sprinkler system, sprinklers with electrical activation, smart system, group of sprinklers
