| 摘 要： | 针对目前煤矿采用的瓦斯传感器输出信号具有模糊性、不确定性等问题,提出了一种基于BP网络和D-S证据理论的瓦斯监测系统的设计方案。该系统采用改进的BP算法获取煤矿环境的基本概率分配,采用D-S证据理论对BP网络输出结果进行信息融合,从而对井下瓦斯状态作出判断和决策。实验结果表明,该系统提高了瓦斯监测信息的准确性和决策的快速性。

| Abstract: | In view of problems of fuzziness and uncertainty of output signal of gas sensor used in coal mine,the paper proposed a design scheme of gas monitoring system based on BP network and D-S evidence theory.The system uses improved BP algorithm to get basic probability assignment of underground environment and uses D-S evidence theory to fusion information of output of BP network,so as to make judgment and decision of underground gas state.The experiment result showed that the system improves accuracy of monitor... |
