摘要:

为提高受限空间内火灾预警的准确性,设计并建立1 套针对受限空间内火灾探测信号可靠性研究的技术,将可燃物燃 烧烟气体积分数的实验研究与神经网络仿真算法相结合,验证受 限空间内火灾探测信号是否满足高斯分布。结果表明:可燃物燃 烧烟气体积分数在误差允许范围内可拟合为二次高斯分布形式。 2 种可燃物燃烧产生的CO 值输出信号服从高斯分布,且在燃烧 产生CO 体积分数是否满足高斯分布的预测值上,航空煤油比正 庚烷更稳定,误差值更小

Abstract: In order to improve the accuracy of fire alarm in a confined space, a set of techniques for the reliability of fire detection signal in a confined space was designed and established. The fire detection signals in a confined space whether meet the Gaussian distribution was verified by the experimental study of combustible smoke concentration with the neural network algorithm. The results show that the concentration of combustible smoke can be fitted into a quadratic Gaussian distribution within the allowable error range. The signal of CO for combustion obeys the Gaussian distribution and predicted value of aviation kerosene is more stable and has a smaller error value by algorithm than heptane, compared with that whether the CO concentration produced by the combustion meets the Gaussian distribution.
