摘要
在透明广告窗两面固定广告画面的基础上,在窗内加可以控制的转动轴,将印制有多幅广告画面的柔软介质(如布料等)卷在轴上,轴的转动由单片机89C51控制,按设置的显示时间顺序更替广告画面,弥补了固定广告窗的不足。
Based on fixing advertising pictures on both sides of transparent advertising window, soft medium with many advertising pictures （such as cloth, etc. ） is roiled on the axis by adding controllable turning axis in the window. The rotation of the axis is controlled by single chip 89C51, changing advertising pictures according to the showing time order, which makes up the disadvantage of fixed advertising windows.
