摘　　要：传统在线教学平台在资源遍历时存在系统占用率过高、会造成平台运行异常等问题,为此提出基于虚拟仿真技术的在线教学平台。首先,利用服务器的智能平台管理接口(Intelligent Platform Management Interface,IPMI)对教学资料进行初代分类,并以教学内容为基础进行二代分类,以此构建系统化的数据库;其次,在数据库中迅速定位教学资源,通过闪电立方将资源迁移到平台内置的虚拟仿真程序中,并转化为程序可利用的FastDFS模式;最后,利用闪电立方将数据迁移到虚拟仿真程序中,实现资源的虚拟仿真展示。实验结果表明,在800用户在线的条件下,反馈时间不超过4.0 s,IO占用率和内存占用率分别为11.4%和8.0%,可以实现稳定运行。The traditional online teaching platform has some problems,such as high system occupancy rate and abnormal operation of the platform.Therefore,an online teaching platform based on virtual simulation technology is proposed.Firstly,the intelligent platform management interface(IPMI)of the server is used to classify the primary generation of teaching materials,and the second generation classification is carried out based on the teaching content,so as to build a systematic database;Secondly,quickly locate the teaching resources in the database,migrate the resources to the built-in virtual simulation program of the platform through lightning cube,and convert them into the fastdfs mode available to the program;Finally,the lightning cube is used to migrate the data to the virtual simulation program to realize the virtual simulation display of resources.The experimental results show that under the condition that 800 users are online,the feedback time is no more than 4.0 s,and the IO occupancy rate and memory occupancy rate are 11.4%and 8.0%respectively,which can realize stable operation.
