Optical Network Remote Control System Based On Internet Of Things

The development of Internet technology is changing with each passing day.It is constantly changing people’s lives and learning methods.With the development of Internet technology,online education has gradually become a hot topic in education industry.The development of online education has fundamentally changed the way of learning.The acquisition of knowledge is no longer limited to the campus,and has become more flexible and diverse.Experimental teaching is an important part of teaching activities,it can effectively train students’ hands-on ability,and at the same time allow students to have a deeper understanding of theoretical knowledge,especially in physics,chemistry and other practical disciplines.However,the application of online education in experimental teaching is scarce.The traditional experimental courses are limited by the fixed location of the experiment and the lack of experimental instrument resources.It is difficult to effectively complete the teaching goals,especially during the current novel coronavirus pneumonia.Due to limitations of objective reasons,students and teachers cannot complete the experimental courses in the laboratory,so the development of remote experimental courses is imminent.After investigation,it is found that most of the remote experimental teaching at this stage is limited to the explanation of theoretical knowledge such as experimental principles and experimental steps.The experimental steps are often explained in the form of videos or slides,ignoring the most important part of experimental teaching,that is,experiments operating.Therefore,this article uses the 3D model animation software Unity3 D and 3Ds Max as tools,and takes the spectrometer and the Michael Sun interferometer as examples to build an optical instrument remote control system based on the Internet of Things.The specific contents mainly include the following parts:First,it mainly studies the 3D model construction and animation software commonly used in the market at present,details the commonly used 3D animation production methods in Unity3 D and 3Ds Max,and lays the foundation for the construction of remote optical experimental instrument control system.Second,taking the spectrometer and Michael Sun interferometer as an example,on the basis of understanding the principles and operation steps of the spectrometer and Michael Sun interferometer,the demand analysis for the construction of a remote control system for optical instruments was completed,and the remote control system was summarized.basic skills.Third,based on 3Ds Max software to build a three-dimensional model of optical instruments,the use of polygon modeling method to build the instrument model,to achieve the combination of instrument shape,equipment components and experimental environment and other necessary elements,completed the near-real spectrometer and Michael Sun Modeling of the three-dimensional model of the interferometer.Fourth,based on the Unity3 D software,the virtual control of the optical instrument model and user interaction are realized,and the animation of the movement,rotation,and light of the threedimensional model object is constructed according to the actual needs,and the experimental effect is designed close to the real.At the same time,the communication mode between virtual interaction and real instruments is designed,and the remote control of optical instruments is realized.In addition,the cross-platform deployment of webpages is realized by using the cross-platform feature of Unity3 D software.This paper takes the spectrometer and Michael Sun interferometer as an example to build the optical instrument model and implement the virtual operation control,which can truly and effectively simulate the operation method of the spectrometer and Michael Sun interferometer in the experiment.Let students have a more real sense of experience in the operation of remote experiments,so that remote experiment teaching is no longer limited to theoretical explanations,and provides new ideas for the development of remote experiment teaching.
