Design of Automatic Fire Detection and Alarm System Based on Multi-modal Information Recognition Technology

An automatic fire detection and alarm system based on Multi-modal information recognition technology is designed. The whole structure of the distributed fire alarm system is introduced in detail. The automatic fire detection and alarm net is established with the smoke-sensor detectors, blaze-sensor detectors, temperature-sensor detectors and manual alarm buttons. The signal is processed through the fuzzy control. The gang control system is made up of fire-proof rolling door, smoke-released fans, broadcasting system and water spray fire fighting system. The Multi-modal information recognition technology can extend the monitoring range of fire alarm system in time domain and space domain. And it also can raise the Sensitivity and reliability of the whole system.
