基于多傳感器數(shù)據(jù)融合的回轉(zhuǎn)窯燒結(jié)溫度檢測和控制方法

燒結(jié)帶火焰溫度檢測是工業(yè)回轉(zhuǎn)窯控制的關(guān)鍵和難點, 基于圖像處理的溫度檢測又容易受到現(xiàn)場粉塵和煙霧的干擾。據(jù)此提出一種利用模糊技術(shù)進(jìn)行多傳感器數(shù)據(jù)融合的溫度趨勢判別方法, 并結(jié)合現(xiàn)場實際歸納了進(jìn)行融合的數(shù)據(jù)種類, 建立了實時專家系統(tǒng)控制策略。工業(yè)實踐表明, 該方法魯棒性強、準(zhǔn)確率高, 具有很強的實用性。

Abstract: The t radit ional alum inum sinter p rocess based on ro tary k iln is difficult to cont ro l because the sintering temperature measurement is easily to be disturbed by the dust and smog in the sintering zone and evil environment. Some senso r data types fo r the fusion are draw n w ith the p ract ical experience. A fuzzy fusion algo rithm based on the data is p ropo sed to judge the t rend of ro tary k iln′s inner sintering temperature. Real t ime expert cont ro l system is int roduced w ith the fuzzy fusion algo rithm. The app licat ion result show s that the cont ro l system w ith th is method can ach ieve h igher robust and bet ter ut ility.
