Intelligent fire alarm system, which has 24 hours of needle alarm for antitheft monitoring and fire alarm, which is all day long in the working state, when there are things such as fire or smoke detection occurs, the alarm will automatically alarm at the same time a people can receive information. The paper is divided into two parts, mainly for software and hardware. The paper for automatic detection in a closed system is how to express the function of automatic alarm system in some specific path in the analysis and Research on the central processor in this system. Mainly by the AT89C52 microcontroller to achieve, is also introduced in this paper. The selected MCU models and some specific function, at present at home and abroad a microcontroller Some research status. This paper also describes the smoke alarm signal generated by the system to the outside world is how to arrange and analysis, so as to realize the monitoring of smoke, fire and other phenomena. The paper is the microcontroller and chip of an anic bination, so as to achieve a better than expected results, achieve the two the main process of prediction and fire, w
