摘要
论述了以STC89C52单片机为核心的多功能导盲器的设计,给出了系统的硬件电路组成,并详细介绍了软件程序的设计思路。导盲器能检测前方、左前方、右前方障碍物的距离,当距离低于设定值时产生振动并语音提醒盲者避让。调试结果表明,该导盲器测量准确,使用方便。
The design of multi-function blind guide based on STC89C52 MCU is discussed in this paper.The hardware circuit of the system are gived,and the design idea of software program is introduced in detail.The blind guide can detect the distance of obstacles in front,left front and right front.When the distance is lower than the set value,it will produce vibration and voice to remind the blind to avoid.The debugging results show that the guide is accurate and easy to use.
