The System Of On-line Infrared Spectrum Data Analysis In The Field Of Biological Engineering

Infrared spectral analysis technology is a rapidly developing new and high technology.Compared with traditional analysis technology, it has a fast analysis speed, less dosage ofsamples, no damage to the sample and pollution, etc. However，Infrared spectrum is verycomplex, artificial solution of the spectrum requires a lot of knowledge and experienceaccumulated,which can only qualitative rather than quantitative analysis. With the rapiddevelopment of chemical metrology in recent decades, spectral data analysis by using chemicalmetrology method has become mature and applied in processing the complex data ofinstrumental analysis system to extract useful information. This method is one of the mosteffective and most systematic method to get from behind the data composition and features of alarge number of qualitative and quantitative information, So it will becomes a powerful tool forspectral data analysis.The content of this study is data analysis system’s design and implementation for online usesin the field of biological engineering. It mainly involved quantitative and qualitative analysis ofthe infrared spectrum data making use of chemical metrology algorithm. This system appliedMVC mode in software design and the use of MATLAB and VC++mixed programmingtechnology.In this article, it firstly introduces the background and research significance of thissystem development, the system’s present situation in the domestic and foreign researches andthe development trend, and the major work of this article. Secondly, it introduces relatedtechnologies used in the design process and the development of this system.It also makesdetailed analysis about the mathematical principle and method of chemical metrology involvedin this paper. Then, it described in detail the main problems of system needs to solve and thedevelopment and design of each function module from requirements analysis, system design,system implementation and system test according to the software engineering theory andobject-oriented programming methods and techniques. Case diagram was used to illustrate themain functions of this system in the requirements analysis module; It analyzed in detail thefunction of the system design module in the system architecture and designed the technicalarchitecture. In system implementation, it realized the main function modules of this system incombination with instance, and the system was tested. Finally, the paper work is summarized andprospect.
