Design And Implementation Of Optical Fiber Communication Online Learning System

The 21st century is the information age,and the application of communication and computer technology is becoming more and more extensive.In order to solve the problem of talent cultivation,many colleges and universities have communication engineering majors.Optical fiber communication is the core course of communication and information related majors.It has the advantages of fast technology update,wide knowledge system,complex networking structure and many practical application scenarios.Features.Most of the existing universal online learning platforms are static learning systems that do not have curriculum-specific and no feedback on learning effects,and do not give full play to the advantages of online education.Therefore,it is necessary to develop a set of optical communication communication online learning system,the purpose of which is to make up the general learning system as a universal learning aid,and there is no application knowledge of fiber-optic communication courses.On the other hand,using the learning effect feedback mechanism,students can get feedback on the learning effects at different stages,adjust the learning plan in time,and better learn the course knowledge.Teachers can sum up and analyze the teaching direction and improve the teaching methods in a timely manner.This thesis first expounds the research background and significance of the online learning.By analyzing the development status and existing problems of online learning platform at home and abroad,combined with the characteristics of optical fiber communication course and computer software development technology,an optical communication online learning system is designed.This thesis studies the content system of optical communication courses and the expression forms of learning resources,and formulates the learning evaluation table.Through the specific analysis of the overall requirements of the system,overall design of the system,and the specific implementation techniques and methods of each functional module of the system are expounded.The system uses data mining technology to realize the feedback function of learning effect evaluation.An evaluation index system was established to mine the students' learning status and learning behavior data.The improved Apriori algorithm was used to establish the relationship between learning behavior and learning evaluation,and the results were presented in the system function.At the end of this thesis,some modules of the system are tested in detail,and it can be verified that the module functions and performance satisfy the design requirements.The main functions of the online learning system for students in this thesis include:student user registration,personal center information query modification,course material learning,message interaction,simulation test,and learning effect evaluation information.The functions for the teacher user include:user information rights management,home page management,data upload classification,test thesis score management,message review reply,evaluation index setting.The system enables students to have a fiber-optic communication learning platform with rich learning resources,evaluation of learning effects,and good interactive learning between teachers and students outside the classroom.
