【摘要】：随着信息化时代的到来,通讯技术和互联网技术等高新技术迅速发展,智能手机就是时代发展的产物。大学生作为极具代表性的群体,受智能手机的影响较大,大学生中“低头一族”越来越多,这种现象在大学课堂也越来越普遍,这也严重影响了正常的课堂教学。本课题的设计初衷不仅是为了能够让学生来上课,同时也是为了能让学生在课堂上好好听课,使得大学课堂更具效率。本课题设计的智能手机袋主要有两大功能:即签到和手机存放功能,主体设计分为:手机袋模型结构设计、硬件电路设计和软件设计。使用Solidworks软件完成班级智能手机袋模型结构设计,并制作了实物模型,它可存放40个手机。硬件电路设计上,考虑到树莓派体积小功能强大,所以本设计采用了最新一代3B型树莓派为主控,分别采用74LS165和SN74HC595扩展树莓派I/O口的数量,满足了设计中用于显示签到状态的输出口LED指示灯和检测放置手机状态输入端口的需求。软件设计包括:学生签到端、教师客户端以及服务器端设计。学生客户端通过界面形式进行签到,使用HTML标签、CSS样式以及PHP语言开发,能够实现二维码扫描界面、学生首次注册界面,学生签到界面,同时将二维码设置一分钟刷新一次以防止学生签到作弊。教师客户端采用C#进行开发,做成Windows系统下桌面软件形式,老师通过打开软件能够直接在线查看所有学生的签到状态以及协助学生进行签到。服务器设计包括软硬件服务器设计和数据交互服务器设计,由于Python能够完美支持树莓派的开发,所以两个服务器设计均采用Python语言进研发设计,软硬件交互服务器启动后,能够监测树莓派输入口电平变化从而改变数据库中有关存放手机签到字段的状态,同时也能通过监测数据库中有关扫码签到的字段变化从而控制树莓派输出口LED灯的亮灭。数据处理服务器主要是为了教师客户端与树莓派上Mysql数据库交互所设计的,由于将教师客户端采用C#编程语言做成了Windows桌面软件的形式,就涉及到与Linux系统的通讯,通过开发数据处理服务器,教师客户端可以直接通过服务器读取Mysql数据的数据,这样老师可以直接在客户端上看到数据库所显示的签到信息以及课程信息。
[Abstract]:With the arrival of the information age and the rapid development of high and new technologies such as communication technology and Internet technology, smart phones are the product of the development of the times. As a representative group, college students are greatly influenced by smart phones. This phenomenon is becoming more and more common among college students. This phenomenon has seriously affected normal classroom teaching. The purpose of this project is not only to enable students to come to class. The smart phone bag designed in this paper has two main functions: check-in and mobile phone storage function, the main design is divided into: mobile phone bag model structure design. Hardware circuit design and software design. Using Solidworks software to complete the class smart phone bag model structure design, and made a physical model, it can store 40 mobile phones. Hardware circuit design, considering the raspberry pie small size powerful, So this design uses the latest 3B raspberry pie as the main control, using 74LS165 and SN74HC595 to expand the number of raspberry pie I / O ports, respectively. It meets the requirements of the LED indicator lamp used to display the check-in status and the detection and placement of the mobile phone status input port in the design. The software design includes: student check-in terminal, The design of the teacher client and the server side. The student client can sign in through the interface form, use the HTML tag and PHP language to develop, can realize the two dimensional code scanning interface, the student first registration interface, the student sign in interface, the second dimension code scanning interface, the student first registration interface, the student sign in interface. At the same time, set the QR code once a minute to refresh once to prevent students from cheating. The client of teacher is developed with C # to make desktop software form under Windows system. By turning on the software, the teacher can directly view all students' check-in status online and assist students to sign in. The server design includes software and hardware server design and data interactive server design. Because Python can perfectly support the development of raspberry pie, the two server designs are developed using Python language. After the hardware and software interactive server is started, The ability to monitor changes in the Raspberry pie input level to change the state of the database where the cell phone check-in fields are stored, At the same time, it can also control the LED light of raspberry pie export by monitoring the change of the scan code check in field in the database. The data processing server is designed for the interaction between the teacher client and the raspberry pie Mysql database. Because the teacher client is made into Windows desktop software by using C # programming language, it involves the communication with Linux system. By developing data processing server, the teacher client can directly read the data of Mysql data through the server. In this way, the teacher can see the check-in information and course information displayed in the database directly on the client.
