摘要
本文介绍了一款基于51单片机为核心的语音导盲系统的设计方案。系统由两部分组成:一是超声眼镜探测器,二是语音提醒器。探测器主要根据超声获取数据,经单片机处理后由无线模块发送出去。语音提醒器由单片机控制,接收数据,然后驱动语音芯片提醒。该系统具有成本低廉、使用方便、等优点,是一款通用性较强的理想导盲设备。
This page mainly introduce a design of voice guide device based on 51 MCU. The device consists of two parts：Part one --ultrasound glasses detector,Part two--voice alarm device. Data gotten from ultrasound glasses detector has been put into process by 51 MCU and then be sent into air by wireless module. After that,the voice alarm device will get the data from another wireless module which has been set as a receiver. Then,the alarm device processes the data received and controls ISD4003 to give a voice alarm.Cheap,convenience and other advantages make it a perfect device for blindman.
