基于51單片機(jī)的語音導(dǎo)盲系統(tǒng)的設(shè)計(jì)畢業(yè)設(shè)計(jì)(完整版)
【正文】 語音提醒 超聲測(cè)距 無線數(shù)傳模塊 導(dǎo)盲系統(tǒng)； II Abstract 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 a voice alarm .Cheap, convenience and other advantages make it a perfect device for blind man. Studies are made on the embedded systems and ultrasonic distance measurement system. Porting embedded operating system and giving optimization method for obstacle detection, and measuring the obstacles distance by ultrasonic ranging works. The experimental results she that the system achieved to deal with circumstance and judge accuracy of realtime requirements in a natural blind road, which may provide better serves for the blind’s independent travel. KEY WORD ： 51 MCU Voice alarm Ultrasound detector Wireless module Guide system for blind 目 錄 摘 要 .............................................................................................................................................
