摘　　要：在Bayes基本算法的基础上,对煤矿输送带运输巷道光纤测温及灭火系统中多点温度、CO、烟雾数据的融合预警方法进行了研究。介绍了通过置信距离选取关联测点的方法,推导出多传感器数据火灾预警危险系数融合算法的最大后验估计式,并对该方法进行了模拟验证。Based on Bayes basic algorithm, the fusion early warning method of multi-point temperature, carbon monoxide and smoke data in fiber temperature measurement and/ire extinguishing system of coal mine belt conveyor was studied. The method of selecting related points by confidence distance is introduced. The maximum a posteriori estimation formula of the fusion algorithm of multi- sensor data fire alarm risk factor is deduced, and the method is simulated and wrified.
