Problems solved by technology

Traditional laboratory TV experiments are limited by time and space and cannot meet the needs of distance education
At present, in remote experimental teaching at home and abroad, multimedia technology is generally used to pre-write or record the experimental content, store it in a file, and call it when it is used. This method is not real-time, and it is not easy to compare with the actual TV image effect.

Embodiment

[0032] figure 1 A schematic diagram of the composition and structure of the TV experiment distance teaching system of the present invention is given. It consists of an experimental server 1, a camera 2, a controller 3, and a color TV set 4 with a modified M11 movement. Experimental server 1 is a computer with PIV / 2.8GHz, 512M memory or above, and USB and RS232 interfaces. The operating software that can complete the experimental requirements is written in it. The operating software includes web pages, experimental project interfaces, etc. The working principle is Operate through the webpage file, check the table file to understand the experiment situation, and see the flow chart figure 2 shown. The camera 2 adopts a CMOS / CCD camera with 1.3 million pixels and has a USB interface output. It is installed on the experimental site and connected to the experimental server 1 through a USB connection. The server 1 interface of the experiment end is connected to the controller 3 t...

Abstract

A remote teaching system of TV experiment based on wideband Internet is featured as sending control command from experiment end to controller by experiment end server then outputting signal to color TV set with modified M 11 core by controller, selecting experimental items and logging on experiment server through wideband internet terminal for carrying out real time simulation TV experiment sending converted real time TV image to said server by shooting tube and sending it to operator terminal after it is coded, finally generating an operator record at experiment end server.

Description

technical field [0001] The invention relates to a remote teaching method for TV experiments, in particular to a broadband Internet-based remote teaching system for TV experiments, which belongs to the technical field of Internet remote two-way information transmission and control. Background technique [0002] Today, with the rapid development of information technology, how to effectively and fully utilize Internet information resources so that more people can receive modern education and improve people's knowledge level is one of the goals that educators strive for. The traditional laboratory TV experiment, limited by time and space, cannot meet the needs of distance education. At present, in remote experimental teaching at home and abroad, multimedia technology is generally used to pre-write or record the experimental content, store it in a file, and call it when it is used. This method is not real-time, and it is not easy to compare with the actual TV image effect. In or...
