The Design And Research On The Remote Control System Based On Socket For The Experimental Teachers

In recent years, with the popularity of the application of the computers and the network, many walks of life, such as the entertainment, the communications, the study and work, have entered an unprecedented information era, which greatly improves the efficiency of peoples'life and job. As one of the technologies that improve a lot both in the speed and scope, the remote control technology started from the DOS era, when no change in the technology, absence of the network, or no market, either. With the development of the network, computer and other technology, it has been paid more and more attention.Adopting Java as the development language, MyEclipse the development tool, and Windows XP as the environment, a Socket-based remote control system is developed in this paper after a detailed study and analysis of key technologies such as network communications. Considering the details of the laboratory and remote control system functional requirements , a C/S remote screen control system schema is raised in this paper with the encapsulation class Socket and ServerSocket in the Java language.The key technology of the system included the network programming and graphical programming with the Java language. The former is adopted to realize the communications of the host and the client, including the transfer of commands and data. The latter is used to perform the interface of the control system. In the data communication module is established with the Socket programming technology, which supports the basic operations of the TCP/IP protocol, shields the underlying details of the network communications and provides the data transfer mechanisms and the ability to session calculation and closing by abstracting the communication nodesIn this paper the control protocol and structure analysis is first addressed with emphasis on the communications of the server and client from four aspects, the screen image, the mouse operation, the keyboard operation and file operation. Based on the above and successful coding, the server and the client can recognize each other and cooperate well. The main function of the system includes the automatic display of the server when it is online. After it, you can operate the files on the mainframe, including the downloading and uploading of files from the remote control host, sending warning to and building session with the remote control host. Furthermore, you can also view its explorer, execute commands and monitoring its screen, .etc. The disadvantage of this system is its deficiency in the safety policy design.
