隨著空氣污染的日益嚴峻，人們對大氣中的污染氣體倍加關(guān)注。CO屬于大氣中的重要污染物。它無色無味，化學性質(zhì)穩(wěn)定，主要來源于燃煤和機動車排氣，當大氣中CO達到一定濃度時，心肌梗塞患者發(fā)病率會增高，達到某一更高濃度時，嚴重心臟病人就會死亡?？梢?，CO作為一種重要的污染氣體應當引起人們足夠的重視。氣體濾波相關(guān)技術(shù) (gas filter correlation，GFC)是一種比較經(jīng)典的弱信號檢測方法，有著很***的用途，通常用在低濃度精確測量場合或有背景氣體干擾的測量場合，它是用充氣池來替代測量濾波器和參比濾波器，參比池充有高濃度的待測氣體，測量池通常情況下充有N2。安譜GFC-500A便攜式紅外CO分析儀采用非分光紅外光譜技術(shù)，基本原理是CO分子對特定紅外光具有吸收效應，基本關(guān)系符合Beer-Lambert定律。該儀器通過設計穩(wěn)定可靠的多次反射吸收池來提高檢測靈敏度，并采用氣體濾波技術(shù)增強復雜環(huán)境下的抗干擾能力。中船安譜儀器符合GFC-500A便攜式紅外CO分析儀符合 GB/T18204.2-2014《公共場所衛(wèi)生檢驗方法》的國家標準，滿足JJG635-2011《一氧化碳、二氧化碳紅外線氣體分析器》中規(guī)定的計量檢測要求，已通過國家計量部門的型式評價，并取得了生產(chǎn)許可證書。上海正規(guī)便攜式紅外CO分析儀推薦廠家</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">傳感器是一種檢測裝置，可以測量物質(zhì)的某種特定信息，并轉(zhuǎn)換成電信號或者其他形式的信號進行輸出。而傳感器之所以具備這一功能，是由于其遵循各種物理、化學或生物規(guī)律，并受對應的定理和法則支配的工作機理。認識及理解傳感器所遵循的定理和法則，有助于更好地運用傳感器進行相應的設計開發(fā)。紅外吸收型co2氣體傳感器就是利用C〇2氣體對紅外光具有選擇吸收作用，立足朗伯-比爾(Lambert-Beer) 定律研制的。因此，必須明確co2氣體的紅外吸收譜線，找出適合設計要求的紅外光區(qū)域的吸收帶，理解Lambert-Beer定律，才能充分利用紅外吸收型C02氣體傳感器來進行設計</p><p> BP神經(jīng)網(wǎng)絡簡介誤差反向傳播(ErrorBackPropagation，BP)神經(jīng)網(wǎng)絡是20世紀80年代中后期由Rumelhart、McClelland等科學家成立的ParallelDistributedProcession小組提出的[30]，它能學習和儲存大量輸入-輸出模式的映射關(guān)系，已經(jīng)證明，BP神經(jīng)網(wǎng)絡不再局限在處理簡單的線性問題上，更具有實現(xiàn)任何復雜的非線性映射的能力，而且無需事前揭示描述這種映射關(guān)系的數(shù)學模型或方程，特別適合求解內(nèi)部機制復雜的問題。解決了多層神經(jīng)網(wǎng)絡的學習問題，極大地促進了神經(jīng)網(wǎng)絡的發(fā)展，成為目前應用*****的神經(jīng)網(wǎng)絡模型之一。在Lambert-Beer定律中的吸收系數(shù)&是一個非常復雜的量，它受環(huán)境溫度、壓強、氣體種類、入射光波長等因素的影響，并且是非線性關(guān)系，無法獲得準確的解析式，如果在測量co2氣體濃度時將環(huán)境溫度、壓強等看成理想狀態(tài)，吸收系數(shù)&考慮成定值，貝IJ失去了在實際應用中的意義。與大多數(shù)紅外co2氣體濃度測量裝置采用**小二乘法對不同環(huán)境下co2氣體的測量結(jié)果進行直線、多項式或**擬合不同，本論文考慮到BP神經(jīng)網(wǎng)絡在解決非線性問題上具有獨特的優(yōu)越性，決定采用這一種新型的建模方案來建立一個“三輸入-單輸出”模型。

隨著科學技術(shù)的不斷發(fā)展和人們對溫室氣體關(guān)注的日益提高，在工業(yè)生產(chǎn)和日常生活等諸多方面都越來越需要對C02氣體的濃度進行監(jiān)測與控制。目前使用的c02氣體濃度分析方法主要有電化學法、電氣法、色譜法、光學吸收法等。其中紅外吸收法因其靈敏度高，精度高，響應快，體積小，可靠性高，壽命長，可以實現(xiàn)連續(xù)分析等諸多優(yōu)點正在成為目前C02氣體濃度測量領域發(fā)展的新方向。本文通過分析c02濃度紅外檢測技術(shù)原理和方法，給出了其硬件實現(xiàn)的系統(tǒng)方案。所述的紅外C02濃度分析儀采用了新型脈沖調(diào)制紅外光源，減少傳統(tǒng)光源不穩(wěn)定性對系統(tǒng)精度的影響。同時，選用了小型氣體傳感器，實現(xiàn)了儀器的便攜性。并通過高精度的～ID轉(zhuǎn)換電路和放大電路對其產(chǎn)生的信號進行采集。以 SyncMOS8958單片機為中心的處理系統(tǒng)對信號進行處理后，將實時地顯示出精確的C02濃度值。儀器真正地實現(xiàn)了c02濃度檢測的高精度、高穩(wěn)定性、便攜性和智能化。 </p> <p> <br /> 上海正規(guī)便攜式紅外CO分析儀推薦廠家</p><p
