Design And Implementation Of Online Monitoring And Statistics Cloud Platform For Multimedia Equipment

The core of education informatization is the efficient application of information technology to teaching and research.And the comprehensive application of modern information technology based on computer,multimedia equipment and network communications is of significance to the education reform.As a vital part of education informatization,the multimedia teaching equipment is required to be strictly checked by the relevant management personnel in terms of equipment configuration and procurement,so as to improve the utilization rate of multimedia equipment.Therefore.it is necessary to provide the relevant managerial personnel with authentic and credible information about multimedia equipment use.In fact,there exist still some problems in the management mode of traditional multimedia equipment,such as information lag,and low data authenticity,which is mainly because the multimedia equipment use information derives from the user's manual registration.This management mode completely relies on the self-discipline of the user and cannot guarantee the authenticity of the data,thus authentic and credible information about the multimedia equipment use cannot be obtained by the relevant managerial personnel.The development of education informatization has been affected by the problems to a certain extent.Therefore,it is crucial to construct a multimedia equipment management platform with equipment information,real-time monitoring and statistical analysis.Aiming at the problems existing in the traditional multimedia equipment management mode,the multimedia equipment online monitoring and statistics cloud platform is designed and implemented in the thesis.The overall platform is divided into three parts,including the lower end data acquisition system,the middle layer data acquisition and processing subsystem,and the upper integrated information publishing platform.A large number of data acquisition modules are included in the terminal data acquisition system.AT89C2051 single-chip microcomputer is adopted by the modules as the core,various modules are expanded to achieve the system requirement function,and the improved AES encryption algorithm proposed in this thesis is embedded in the single-chip microcomputer program.The traditional AES encryption algorithm is improved so as to make the AES encryption algorithm run on the single-chip computer in the data acquisition module more efficiently.Considering the limited resources inside the single-chip computer,in this thesis,the improvement of AES encryption algorithm mainly focuses on the performance improvement.Compared with the traditional AES encryption algorithm,the improved AES encryption algorithm can complete the data encryption process in the single-chip environment more efficiently.The data acquisition and processing subsystem is responsible for collecting and processing the data generated by the lower terminal data acquisition system.Concerning the business logic characteristics of the data acquisition subsystem and the data storage mode of the database server,a storage optimization strategy is proposed in the thesis.This strategy is used to reduce the redundancy caused by data packets in the process of data collection.which has effectively solved the problem of data redundancy in the database,and reduced the burden of data processing server and database server in the data center.The Tomcat server,Java language and MySQL database are selected as the necessary material by the upper comprehensive information publishing platform to construct the development environment,and the software is coordinated and configured to meet the development requirements.Through related tests,the online monitoring and statistics of multimedia equipment can be realized on the platform.
