Intelligent fire alarm system

Abstract

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.

Description

technical field [0001] The invention belongs to the field of fire monitoring, in particular to an intelligent fire alarm system. Background technique [0002] The traditional fire detection and alarm technology is that the fire detector perceives certain fire parameters on the scene, such as smoke concentration, temperature, etc. When these parameters reach a certain limit value, the fire detector sends a fire alarm signal to the fire alarm controller, and the fire The alarm controller sends out an audible and visual alarm. The fire criterion of the traditional fire detection and alarm system is only determined according to whether a certain fire parameter reaches a certain value. This discrimination is realized by the hardware circuit in the fire detector, so it may be affected by the environment , or the slow drift of the internal circuit of the fire detector, generating false alarms. Contents of the invention [0003] In order to overcome the deficiencies of the above...
