Abstract:

 Aiming at the problems of single detection and simple function of the traditional building fire alarm system, The solution is put forward in this paper that a fire alarm system can be used，which takes MCU as the lower computer, LabVIEW as the upper computer and adopts Bayesian algorithm of multiple sensor information fusion. In this system, Bayesian fusion algorithm is applied to fire alarm detection, and the collected fire data are preprocessed. At the same time, the data fusion of Bayesian network algorithm is simulated and analyzed by using MATLAB software. The simulation results show that the system can monitor the environmental factors related to fire accidents in the building in real time, and the integration of the three characteristic quantities improves the balance degree and accuracy of the response to the fire characteristic signals, thus greatly improving the reliability of the system, which provides a reference for the design and application of the building fire alarm system.
