Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] like figure 1 As shown, a data transmission system 100 for interactive teaching in the present invention includes a teacher terminal 10 , multiple student terminals 20 and a router 30 . The router 30 is used for address resolution and data forwarding. The teacher terminal 10 is usually a computer, such as a desktop or a notebook computer, and the student terminal 20 is preferably a tablet computer. Obviously, the student terminal 20 can also be a desktop computer or a notebook computer. The system 100 is embedded in the teacher terminal 10 and the student terminal 20 in the form of softwar...

Abstract

The invention is suitable for the field of electronic teaching and provides a data transmission method and a data transmission system both used for interactive teaching. The method includes that a teacher end sends file transmission starting control information to multiple student ends by means of TCP / IP (transmission control protocol / internet protocol) and sends UDP (user datagram protocol) data packets to predefined multicast IP addresses and ports by means of UDP / IP; the student ends monitor the multicast IP addresses and the ports and receive the UDP data packets; the teacher end sends file transmission ending control information to the student ends by means of TCP / IP; the student ends examine whether packet loss occurs or not, if yes, feeding packet loss information back to the teacher end by means of TCP / IP; the teacher end resends corresponding UDP data packets according to the packet loss information; the student ends analyze and store the UDP data packets. By the method and the system, network environments of the teacher end and the student ends in classes can be compact and single. The data transmission method and the data transmission system have the advantages of stable data transmission, timely control response, low cost in maintenance and development and the like.

Description

technical field [0001] The invention relates to the field of electronic teaching, in particular to a data transmission method and system for interactive teaching. Background technique [0002] Under the national policy planning, local governments and education departments are intensively investing in the research and development project of "e-schoolbags". Through the digitization of e-schoolbags and supporting resources, the reuse rate of teaching resources is improved, energy conservation and emission reduction are promoted, and the content is rich and interactive. Strong, easy-to-use digital teaching publishing system for students and in line with the reading habits of young people, promotes the development of electronic schoolbags, resulting in the emergence of many digital teaching products such as "cloud electronic schoolbags" and "classroom interactive teaching systems". [0003] The conventional "classroom interactive teaching system" is divided into a teacher's end a...
