介绍了一种计算机通过利用双音多频(DTMF)码进行控制的多媒体数学集中控制系统的工作原理。控制方法简单可靠，利用电话可以进行远程控制。控制码开放，教师可将控制码做在教学软件(CAI课件)中，以使多媒体教学集中控制系统完全自动化。“,”The authors introduce a principle that the computer ocntrols the multimedia teaching centralized monitoring system by using of DTMF. This method is simple and dependable. Only through telephone, the teachers can make the remote control. The control code is open. The teachers can put the control code into the teaching software(CAI) so as to make the multimedia teaching centralized monitoring system automatized.
