【摘要】 伴随着校园无线网络的不断发展，结合射频识别技术（RFID）为高校师生建立一个实时、便捷的课程信息查询平台已经成为可能。本文的目的是开发一款可以通过RFID技术快速识别附近教室课程信息，利用移动互联网快速分享课堂实时信息的网络平台。本方案采用经典C/S结构。服务器端选择自由软件Postgres，在Ubuntu PC上实现；客户端软件采用Qt编写，在ARM+Linux平台上实现。客户端设备外接RFID阅读器，用于读取标签信息并发送给客户端应用；通过网络与数据库服务器端通讯。数据库中存储教室，课表，教师，学生和交流贴等信息；客户端读取放置于教室门外的标签以获取教室标识，然后通过移动互联网连接数据库获取相关教室课表信息，并可实现教师和学生登录交流。逐渐普及的配备NFC的智能手机是运行客户端的理想设备。最终实现的系统可以在数据库服务器端在线更新信息，在客户端显示课表、寻找空教室、师生实时互动交流等功能。RFID技术识别迅速，移动互联网接入便捷，实验结果显示本系统可有效提高师生的沟通、交流效率。实验结果表明，本论文实现的系统是有效的，而且是便捷的。更多还原

【Abstract】 We can provide campus professors and students a convenient, real-time and open takingclass and learning platform. Combined with the convenience of Radio frequencyidentification (RFID) technology and the progress of campus network in full swing, we candevelop a solution for professors and students. It can be a more convenient channel ofcommunication. We can apply the RFID technology to quickly identify nearby classinformation and use mobile Internet to share the class information fast.The solution adopts the classic C/S structure. The database server adopts Postgres,which runs on the Ubuntu personal computer; the client adopts Qt, which runs on the LinuxARM board. The client device connects to the RFID reader to read the information that storesin the tag and then send it to the client app. It communicates with the database server via theInternet. The database stores the data about classrooms, curriculum, professors, students andposts; the client reads the tag which is placed outside the classroom, then connects to thedatabase via mobile Internet to get information about the classroom and provides a platformfor professors and students to communicate. Smart phones which equip with NFC are theideal equipment for the client device.The final system can update data on the database server side, and display classschedule, look for classrooms for those who want to take a class or study by oneself, andpromote the interaction between professors and students. The RFID identifies smoothly, themobile Internet is convenient. The result of the project shows that the solution can improvethe efficiency of learning, working, and interaction of campus professors and students.Therefore, the solution implemented in this paper is not only necessary but also pleasant andconvenient.更多还原
