摘要
因盲文书籍价格高,盲文出版物的品种和数量有限,难以满足我国900万盲人的阅读需求。设计了一种以微型步进电机为主体、PC机作上位机、单片机作主机和从机的盲文助读器,能将电子版的文字转化为盲文凸起形式。
Because of the high price of books in braille and the limited quantity of braille publications,it＇s very difficult to meet nine million blind people＇s reading demands.In this paper,a kind of braille read device is designed,which makes miniature stepper motors as the main components,a computer as the upper,several microcontrollers as master and slave computers,transforming the words of electronic version into braille convex form.
