Intelligent fire alarm system

The invention discloses an intelligent fire alarm system which comprises a data acquisition module, wherein an output end of the data acquisition module is connected with a single-chip microcomputer; the single-chip microcomputer is connected with and used for controlling an alarm device and fire-fighting equipment; the data acquisition module comprises a smoke sensor, a signal processing module and a comparison and conversion module which are connected in sequence; the smoke sensor is used for converting a field smoke concentration non-electric signal into an electric signal, inputting the electric signal to the signal processing module for performing signal filtration and amplification, and then outputting the filtered and amplified electric signal to a comparison and conversion module, so that conversion of an analog signal output by the smoke sensor into a digital signal is finished; an output signal is connected with the single-chip microcomputer; the single-chip microcomputer is used for performing signal processing and realizing a sound-light alarm function and an action of the fire-fighting equipment through control. The intelligent fire alarm system can intelligently monitor an environment and give an alarm in time in case of fire, and has the characteristics of accuracy for monitoring, quickness and high sensitivity.
