A fire-alarm prediction system based on multi-sensor information fusion is presented

the block diagram of the system hard-ware is introduced

the soft-decision information fusion rule and its application in fire-alarm prediction is explained.The system firstly is divided the specific observation domain by three seosors

namely smoke

flame and temperature in the fire time

and information is fused according to Bayesian principle

thus finally an optimal judgment on the fire situation is obtained.The conflict of alarming sensitivity and false prediction rate are solved.Also the system possesses features such as simplicity of structure

easy of realization and low power consumption etc.
