This course of development of the electronic classroom, a comprehensive summary of current research, analyzes trends in electronic classrooms, clarified shaped machine developed electronic classrooms significance and necessity; pair ITS minicomputer constitute heterogeneous network, electronic classrooms conducted a study and analysis, a simple, economical, versatile solution, summed up the program's design and implementation process; construct shaped machine electronic classroom system models. No card included in the upcoming PC LAN minicomputer to a microcomputer minicomputer line system as a common terminal, the same time as the entire electronic classroom teacher computer systems, the use of microcomputers minicomputers terminal simulation in order to establish the basis of the simulation program heterogeneous communications platform, to achieve a minicomputer and microcomputer LAN communication and resource sharing, and then complete the heterogeneous electronic classroom based module designs. System function modules include: running on minicomputers the P process, LOGIN process, SPEAK process; runs on teachers on the machine TUTOR process, INTER process, teachers frmclass process, frmanswer process, FTP process; running on computer student on student frmclass process, frmaskpro process. The electronic classroom system's main features include screen monitor, radio transmission, remote control, discussion forums, file transfer, whiteboard and so on. The system research and design process mainly involves analysis of hardware and software environment, shaped machine has no network card interconnect, terminal emulation, shaped machine communication, resource sharing, binary file transfer algorithms, concurrent processes, database dump and sharing and other key technologies, the use of The concept of distributed systems DSM completed the minicomputer some basic electronic classroom software design, the use of Winsock completed some electronic classroom microcomputer main function module, using the concept of concurrent processes studied teacher computer software integration problems, make the special shape users achieve maximum transparency between communication and adequate sharing of resources, given the weakness of heterogeneous electronic classroom and Solutions proposed system's overall goals, and strive for the development of similar systems to provide theoretical guidance. The program can avoid complex network integration issues as well as differences caused by shielding protocol efficiency, while also taking into account any lack of peripheral equipment, lack of funds and not networking problems.
