    摘要:

    傳統(tǒng)的近紅外光譜分析系統(tǒng)是單機(jī)版,,建模工作難度大,。為了在近紅外光譜分析中實現(xiàn)對現(xiàn)有光譜模型資源共享,,提出利用云計算中心的高性能服務(wù)器代替單機(jī)版的主機(jī),,然后在云服務(wù)器上開發(fā)近紅外光譜軟件分析系統(tǒng),并詳細(xì)分析了近紅外光譜云分析系統(tǒng)的構(gòu)架與設(shè)計步驟,。該系統(tǒng)可以實現(xiàn)近紅外光譜數(shù)據(jù)的預(yù)處理,、定量分析,、定性分析以及光譜模型查找和光譜模型轉(zhuǎn)移等功能,。最后以潲水油近紅外光譜定性鑒別為例,分析比較了單機(jī)版和基于云計算的近紅外光譜分析結(jié)果,。在近紅外光譜云分析系統(tǒng)中,,對預(yù)測集58個樣品進(jìn)行判別,總體鑒別正確率為86.21%,,這一結(jié)果與在單機(jī)環(huán)境下的分析結(jié)果完全一致,。實驗結(jié)果表明近紅外光譜云分析系統(tǒng)具有成本低、建模方便,、接入方式靈活,、可實現(xiàn)資源共享和遠(yuǎn)程訪問等優(yōu)點。

    Abstract:

    Traditional NIR systems are stand-alone and difficult to model. In order to share resource of existed NIR model, a NIR analysis system based on cloud computing is proposed. The NIR software analysis system is designed on a high performance server instead of the host of stand-alone version, and the architecture and design procedures of the NIR cloud analysis system are described in detail. The system has the functions of preprocessing of near infrared spectral data, quantitative analysis, qualitative analysis, spectral model search and spectral model transfer. The identification results of waste edible oil between NIR cloud analysis system and stand-alone version are compared. The overall rate of correct identification is 86.21% for the 50 samples of waste edible oil by the NIR cloud analysis system. This result is fully consistent with the analysis results in stand-alone. The experimental results show that the cloud NIR analysis system is low cost, easy modeling, access to flexible, enabling resource sharing and remote access, etc.
