To avoid fires and reduce fire losses, we must follow the hidden dangers fire in prevention is better than disaster relief, the responsibility is extremely heavy, the concept design and improvement of automatic fire alarm system, fire nipped in the bud, the maximum reduce the loss of social wealth. In this design, fire alarm system is to use sensors, integrated chips, display module to design an intelligent fire alarm system。 Integrated chip as the core, whole function analysis of the detection and alarm system, the main implementation aspects of major hardware and software design, and the concentration of display and troubleshooting alarm line set up. First choice of main chips were briefly introduced, with points module to achieve the function of its parts, finally makes the corresponding principle diagram of the whole.
