，目前國內(nèi)多數(shù)氣體檢測(cè)儀器的光源都采用鎳锘絲作為光源，并使用機(jī)械轉(zhuǎn)動(dòng)的方法調(diào)制光源，這就造成了光源的 </p> <p> 不穩(wěn)定和抗震性差等缺點(diǎn)，在本儀器的設(shè)計(jì)過程中充分的考慮到該因素，所以本儀器選用了PerkinElmer公司生產(chǎn)的IRL715紅外光源，該光源發(fā)出的波長范圍為從可見的光波長到59in，在5V電壓驅(qū)動(dòng)下工作壽命可達(dá)40000小時(shí)，輻射強(qiáng)度為0．15±10％MsCP。同時(shí)，IRL715的玻璃外罩可以濾去5岫以上紅外光對(duì)測(cè)量結(jié)果的影響，從而增加了傳感器吸收帶寬的發(fā)射率并且降低了帶寬之外的發(fā)射率。比較大化有用帶寬的比率，提高信噪比。但由于紅外傳感器對(duì)光強(qiáng)的變化是敏感的，而對(duì)光的***強(qiáng)度不敏感， </p> <p> 因此必須利用單片機(jī)產(chǎn)生的脈沖信號(hào)對(duì)其進(jìn)行調(diào)制，在設(shè)計(jì)中采用了ls開5s關(guān)的間歇工作模式，這樣做一方面使光源調(diào)制深度加 </p> <p> 強(qiáng)，另一方面減小儀器功耗并延長光源的使用壽命，**重要的是在此工作模式下，傳感器、放大器和其它元件的寄生熱減少，可以極大提高系統(tǒng)的信噪比和穩(wěn)定性。另外，為了確保光源的穩(wěn)定性，在電源方面系統(tǒng)采用了高精度的ADP3330來獲得穩(wěn)定的5V工作電壓。從根本上提高了光源供電的穩(wěn)定性，在保證傳感器輸出電壓的精確性方面起到了至關(guān)重要的作用。 </p><p> 在煤礦井下、化工廠、鋼鐵冶金等行業(yè)中都有大量的cO生成，日常生活的天然煤氣也含有大量的cO。特別是當(dāng)井下發(fā)生煤層氣泄漏或在特殊煤層地質(zhì)條件下，可能使礦井CO氣體涌出局部積聚而超標(biāo)，因此檢測(cè)C0對(duì)維護(hù)工業(yè)安全生產(chǎn)、預(yù)防中毒和保障工人生命安全具有重要的意義。本文通過分析cO濃度紅外檢測(cè)技術(shù)原理和方法，給出了其硬件實(shí)現(xiàn)的系統(tǒng)方案。紅外熱釋電紅外探測(cè)器輸出的原始信號(hào)為mv 級(jí)，為了提高測(cè)量精度需要對(duì)信號(hào)進(jìn)行放大和濾波，信號(hào)調(diào)理電路如圖1，由于測(cè)量信號(hào)和參考信號(hào)的調(diào)理電路結(jié)構(gòu)是完全一致的，圖1只給出其中一路的調(diào)理電路，放大器選用‘幾C2254，它具有輸入噪聲小、輸入阻抗高、開環(huán)增益大等特點(diǎn)。輸入信號(hào)首先經(jīng)過隔直電容cl，濾除原始信號(hào)中的受溫度影響較大的直流電壓，得到類似正弦的交流信號(hào)，輸出信號(hào)為一平滑穩(wěn)定的正弦信號(hào)，其直流偏置為事先設(shè)定的+1．65V。．
