In view of the present problem that the mine fire early warning system processes data unreliable in coal mine

took the microcontroller as the central processor

based on the fuzzy information fusion theory

the multi-sensors is applied to carry on monitoring to the coal spontaneous combustion target gas and the parameter

monitoring facilities’many sensors will obtain information fuzzy

again its fusion

thus the equipment precise state estimation is gained.This system carries on the fusion operation and the decision-making to each kind of parameter using the information fusion technology

and the coal bed spontaneous combustion early prediction is realized.The experimental result shows that recognition rate of accuracy and the reliability of coal mine fire early warning system based on information fusion is enhanced greatly.
