Design And Implementation Of The Wisdom Classroom Teaching System

The purpose of wisdom classroom teaching system is to adopt data acquisition technology,intelligent analysis technology,computer network communication and computer software technology,based on cloud computing and internet of things,according to the trend of IT infrastructure development,the traditional teaching business process and the intelligent IT process are matched,constructing the wisdom classroom teaching system with interactive teaching as the core element,the wisdom classroom as the technical support,the information,automation and interaction as the features.This system divides the teaching business into the basic construction module,establishes a network application platform based on B / S structure used in the wisdom classroom teaching,through the interconnection with the education cloud platform,to realize the sharing of high-quality educational resources,to expand its application and promotion,and to improve the teaching quality in an all-round way.The wisdom classroom teaching system is supported by the construction of wisdom classroom,the key is to centrally manage the complicated equipment system in the wisdom classroom,so as to build a good equipment network management layer that is well connected with the teaching business process.Its hardware platform is built on the core of the optical wireless switch and its distributed wireless system,it mainly consists of loading the Wi Fi module in the wisdom classroom system and the optical wireless switch to form a wireless LAN access teaching system.In addition,the wisdom classroom is arranged by adopting the intelligent access gateway and the distributed wired system for the equipment system which is inconvenient to be accessed in a wireless manner to form a wired local area network access teaching system,this design ensures that a comprehensive application platform of wisdom classroom teaching system is constructed on the basis of Internet of things application.The design of the wisdom classroom teaching software is based on the B / S mode development,adopts the three-tier architecture of Spring MVC as well as the technologies such as Java,Eclipse,My SQL database and so on,so as to meet the cross-platform requirement as the core element,and is designed according to theconfiguration mode of the software module of the data presentation layer,the functional application layer,the data processing layer and the interface adaptation layer,which not only effectively improves the operability of the system,but also enhances the user's personal experience.Data sharing between different modules of the system communicates with data and message bus standard protocol,so as to form a scale loosely coupled distributed system,users do not need to rebuild the system for the growth of network and demand.Because the teaching system is provided to the multilevel users of the school teachers and students,the response time of the system transaction is optimized,the success rate and the CPU and memory occupancy rate are the keys to ensure the load balance and fault take-over in the case of multi-user login in the teaching system.By constructing the "Linux-Nginx-tomcat" distributed cluster server,use lvs as load balancing and dual-machine hot standby,increase system transaction response time,success rate,and reduce CPU and memory occupancy.Through the above design,we meet the performance needs and functional needs of the smart classroom teaching system,and verify that the system has high practical value and scalability through practical tests.
