摘要
为实现实验室、机房的电子化管理而开发的电子教室系统,可以对学生、设备和教学过程进行管理,系统还可以用于学生上课情况监督、教师教学督促、PC机状态监控、电子设备运用管理等。构建教学监控网络获取学生上课的考勤数据、教师教学质量的评估数据、机房硬件的损坏数据等。系统主要功能有屏幕广播、远程协助、执行命令、锁定客户端、信息发布、机器重启、自动签到、群组会话、文件传送、作业发布与上交、客户端屏幕监控、设备监控等。使用组播技术完成服务器与多客户端的通信,通过TCP连接数完成客户端在线验证等。利用MVC分层结构完成系统三层架构和数据交互实现,有效提高了数据的安全性和模块的可复用性。系统可以高效地扩展到大规模的实验环境,有效提高电子教室的科学化管理水平。
In order to implement electronic management of laboratory and computer room, an electronic classroom system is developed, which can manage students, devices and teaching process. The system can also supervise the student class situation, and urge teacher teaching, and monitor PC machine condition, and manage electric equipment. The teaching monitoring network is constructed to obtain check-in data of students in class, assessment data of teachers＇ teaching quality, and damage data of computer hardware. The system im- plements main functions including screen broadcast, remote assistance, command execute, client lock, information publishing, computer restart, auto check, group session, document transfer, assignment and submiting, and equipment monitoring. Multicast techniques are used to finish the communication between server and multi-clients,and the connector number of TCP can be used to verify client online. MVC layered structure is utilized to realize the 3-layers architecture and data interaction, which can efficiently improve the security of data and reusability of module. The system can be extended to large-scale experimental environments, effectively improving the scientific management level of electronic classroom.
