The positioning and effectivenes identification system of fire- fighting facilities was established based on the advantages of internet of things and big data. The key technology, network architecture and technical characteristics of the system were introduced. The system can track, inspect and identify the service status, integrity, effectiveness and other functional characteristics of fire-fighting facilities such as fire extinguishers, to realize the intelligent management of fire extinguishing facilities, improve and optimize the construction of fire- fighting facilities, enhance the reliability of fire extinguishers, and give full play to the advantages of intelligent fire protection technology in the construction of intelligent city.
