Design And Implementation Of Remote Education Platform Based On The Technology Of Embedded Mobile Terminal

With the development of computer network technology, the application and popularization of the distance education has become more and more popular, the related technology has become mature and humanity. However, distance education is still in the initial stage in the field of experiment teaching, but also has many problems: If the terminal equipment must rely on the network and the network laboratory configuration cumbersome, slow response speed, instability and so on. Remote network experimental teaching problems this thesis focuses on the research of science and engineering, the design and implementation of remote experiment education system based on mobile terminal remote direct access to experimental device interaction experiment, solve the network laboratory cumbersome configuration, network terminal must rely on the computer, and the laboratory of high cost, difficult to popularize the traditional problems, realizes the application of and innovation of distance education technology in the field of laboratory teaching.The research work of the dissertation is as follows:1. This thesis proposes to use Android mobile phone as a client login, remote laboratory experiment. Because the Android mobile phone and other low cost, thus the economy less developed area students can perform remote experiment through the system, making the educational cost minimization. And because the characteristics of mobile phone is convenient to carry, so that students’ learning time is more flexible, to achieve the purpose of learning whenever and wherever possible.2. Using Arduino microcontroller to replace traditional server control experimental equipment, one is to reduce the cost and difficulty of network laboratory configuration, allowing more traditional laboratory can be a simple network, provide more resources for the remote experimental teaching laboratory. In addition, Android mobile phone and Arduino MCU P2 P direct way to improve the stability and efficiency of the network connection.3. The system in addition to online experiments also implement course of study and multidimensional evaluation module, reflects the integration of learning, experiment and evaluation target. The students’ learning module in the course can view the course information; watch the experiment demo video, online and students, teachers to discuss. The teacher can update the learning materials, answering questions in the discussion area; Finish, experimental report, discusses the evaluation area of the active degree by multi dimension in the evaluation of students’ experimental module.4. The system is based on P2 P architecture, C/S, and MVC mode, the client uses the Android programming, the server through the Servlet programming, data communication server and client APP using lightweight JSON data format, help to improve the efficiency of data transmission. The experimental equipment control part is programmed by Arduino microcontroller. The teacher and the students learning, most of educational function of mobile phone use login server Android C/S architecture. While in the experimental module, system using Socket programming technology, the realization of mobile phone and the remote experimental equipment of P2 P connection, eliminating the intermediate link server, accelerate the speed of data transmission, and avoid the network delay impact on real time experiment, and improve the stability of the remote experiment. Finally the paper validated on the system function, performance and other aspects.
