Design of intelligent fire detection and alarm system

This paper fire safety is an important part of social public safety, although China has made a certain development in the intelligent fire detection technology, but there are still problems such as detection accuracy and response speed, environmental adaptability and cost maintenance. Based on the above problems, in order to improve the fire monitoring rate and reduce fire events, a multi-mode comprehensive fire detection and alarm system is designed. The design is designed by Keil 5, the principle is that the flame sensor and carbon monoxide sensor work at the same time, can detect the gas and flame at the same time, and combined with the data fusion, greatly improve the accuracy rate, reduce the false positive rate, and combined with the GSM module to solve the problem of unable to real-time feedback. At the same time, it can also control the pump, fan and window through the GSM module to effectively mitigate the fire situation.
