Rare Wood Identification Mobile Near Infrared Cloud Service System Design And Implementation

The application of near infrared spectroscopy in the identification of wood varieties has been a lot of research.In a laboratory environment,some qualitative analysis method based on near infrared spectroscopy and chemometrics,has been able to well specified separation and identification of some species within the wood,and has high accuracy.The near infrared spectrum detection equipment of large volume,it can only be placed in the laboratory,analysis of materials can only be transported to the laboratory for spectral analysis,which limits the application of near infrared spectroscopy and moving ability of working out.To establish an analytical model for the near infrared spectrum analysis of a certain field or product,This process is consumption of manpower,the modeling cycle is very long,the modeling cost is very high,but also by the modeling procedure of programming language restrictions,can not be ported to different platforms,these shortcomings restrict the popularization and application of this technology.Combined with the above background,this paper proposed and designed a set of mobile near infrared rare wood identification cloud service system based on the research results of the present stage in the field of wood identification.The system uses the previous exploration of near infrared spectroscopy in wood identification field,combined with the concept of cloud computing and cloud server program development technology,put forward a kind of from near infrared equipment to the client,the client program to the server,the three layer architecture.The identification model of the rare wood is deployed to the cloud,exposing the interface to provide client access.Then,based on the Forms Windows application and Android application,the corresponding near infrared rare wood detection client is developed.The client application connects the near infrared device,which can control the device to obtain the spectral data.The client is also responsible for the communication with the cloud server,the spectrum data to be calculated through the network to the server program to calculate and accept the return results.The portability of the equipment is conducive to the realization of near infrared spectrum acquisition of mobile field operations,while the cloud computing has overcome the mobile devices such as Android mobile computing power is weak,time-consuming problem.The research and implementation of the content of this paper is divided into four parts: 1)SIMCA classification discriminant prediction calculation model of rare wood near infrared spectroscopy;2)build the cloud server application based on ASP.NET API;3)Windows Forms client program construction and suitable for touch panel operation design experience;4)Android client application construction.The design and implementation of this system provides an effective solution to solve the defect of traditional near infrared spectroscopy technology in the production and application.
