Design And Application Of Fire Alarm System

With the rapid development of economic,a increasing number of Intelligent building is used in our lives. It brings us so many benefits while it also gives us so many security risks,for example fire is the most harmful aspect in it . In order to reduce the number and the probability of fire and reduce the loss of people and protect the lives in the fire the most efficient thing is to prevent the fire or over it in the primary stage.This paper first gives the definition of intelligent buildings and the hazards of in it.then give a mathematical model to determine whether there is a fire occurred. This paper mainly discusses the threshold comparison and Bayesian estimation method in the fire alarm system. And analysis of the principles of fire detection and future trends.In the next part ,it main tell the composition of the fire alarm system, it contains fire detection section, data processing section, and linkage control part. And then from the side of hardware ,it builds a fire alarm control topology and design the communications, interface circuit selection .From the software, it designs the whole fire detection and alarm system.The 4th chapter use the example of fire alarm system in Hubei Traditional Chinese Medicine Hospital building, design the whole system and Some equipment such as fire alarm detectors manual alarm button and some linkage equipment. From the practical item ,we can test the rationality and feasibility of our design. This process make me may take the thing that in the future work ,we will think more reality factors in theory research.
