摘    要:针对火灾信号特征参数的模糊特性,采用混沌量子遗传算法对模糊最小二乘支持向量机的参数进行优化,建立基于模糊最小二乘支持向量机的火灾信号辨识模型。研究结果表明:基于混沌量子遗传算法的模糊最小二乘支持向量机火灾辨识模型相对误差为1.1%,具有较高的辨识精度;火灾信号辨识性能指标即O2质量分数减少值权重γ1、H2质量分数权重γ2、烟气质量分数权重γ3、温度权重γ4和CO质量分数权重γ5满足:γ3>γ4>γ5>γ1>γ2

Abstract: Due to the fuzzy identity of characteristic parameters for fire disaster signal, a new model of fuzzy least squares support vector machine signal recognition of fire disaster was developed based on chaos genetic algorithm, in which the parameters of fuzzy least squares support vector machines were optimized by using chaos quantum genetic algorithm. The results show that the recognition relative error of fire disaster signal recognition model is 1.1%, and it has high accuracy. The weight of capability indexes γ15 for fire disaster signal recognition can be expressed as follows: Flue gas concentration γ3>temperature γ4>CO concentration γ5>O2 concentration γ1>H2 concentration γ2.
