礦井通風瓦斯數(shù)據(jù)融合技術研究.pdf

1、論文題目：礦井通風瓦斯數(shù)據(jù)融合技術研究專業(yè)：安全技術及工程碩士生：申慶濤（簽名）＿＿＿＿＿＿指導教師：張儉讓（簽名）＿＿＿＿＿＿常心坦（簽名）＿＿＿＿＿＿摘要近年來，隨著煤礦開采深度的增加和綜采方法的應用，井下環(huán)境安全狀況日益復雜，傳統(tǒng)的數(shù)據(jù)處理方法很難準確把握井下環(huán)境的安全狀況，將多傳感器應用到煤礦井下環(huán)境監(jiān)測監(jiān)控系統(tǒng)是一種必然趨勢。礦井通風瓦斯監(jiān)測監(jiān)控系統(tǒng)是一個動態(tài)系統(tǒng)，監(jiān)測數(shù)據(jù)的冗余性和煤礦安全影響因素的不確定性已經成為礦井數(shù)據(jù)處

2、理的難題。通風瓦斯數(shù)據(jù)融合技術不僅有效地降低了礦井環(huán)境安全影響因素的不確定性，而且能夠提高礦井環(huán)境安全狀況預測的可靠性。本文提出了一種二級數(shù)據(jù)融合結構，不僅可以得到精確的礦井環(huán)境參數(shù)，而且又保證了煤礦安全一致性判斷，進而解決了監(jiān)測數(shù)據(jù)冗余性和煤礦安全影響因素的不確定性問題。二級融合模型采用了一種局部并行和整體串行的融合結構，既解決了局部同質監(jiān)測數(shù)據(jù)冗余性問題，又體現(xiàn)了整體異質監(jiān)測數(shù)據(jù)的互補性。本文將數(shù)據(jù)融合理論應用到煤礦監(jiān)測監(jiān)控系統(tǒng)中，

3、除了瓦斯?jié)舛?，主要考慮了CO濃度、溫度和風速等對煤礦安全具有影響的各種環(huán)境因素。論文首先對監(jiān)測監(jiān)控數(shù)據(jù)進行統(tǒng)計方法分析和偏最小二乘回歸分析，然后對監(jiān)測監(jiān)控數(shù)據(jù)進行自適應加權數(shù)據(jù)融合算法的一級融合，提高了監(jiān)測數(shù)據(jù)的精度；最后采用灰色關聯(lián)分析二級融合，以瓦斯、CO、溫度、粉塵和風速的一級融合結果為輸入，以礦井環(huán)境安全等級為輸出，結合Matlab仿真技術，完成了對煤礦井下環(huán)境安全狀況的預測。本文將數(shù)據(jù)融合和控制論思想應用于通風瓦斯監(jiān)控系統(tǒng)中，
