| Abstract: | In order to promote the digital, intelligent and humanized development of modern teaching process, combining virtual technology with embedded wireless technology and using full-LCD （Liquid Crystal Display） touch screen as the control terminal to complete all system control order. Through the 2. 4 G wireless transmission, the instructions and data on the touch screen can be sent or received to realize the interactive communication. PC software is written by LabVIEW and combines the teacher mode with interactive mode perfectly. The experiment has shown that six groups of student terminals and one host terminal can connect with each other smoothly and simultaneously, the touch panel shows quick processing speeds, the wireless modules and PC display speeds are satisfactory as well. |
