摘　　要：为推动现代教学环节中数字化、智能化与人性化的发展,将虚拟技术和嵌入式无线技术相结合,采用全触控式液晶屏作为终端设备的控制端,完成系统所有的控制命令。通过2.4 GHz无线传输,将触摸屏上的指令及数据进行发送与接收,实现教学的互动交流。上位机软件采用LabVIEW编写,将教师模式和互动模式有机地结合起来,其编写的界面漂亮实用。通过实验表明,6组学生终端与主控端的连接测试高效,触摸屏的书写速度、无线模块的传输速度和上位机的显示速度令人满意,达到了智能化的标准。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.
