摘　　要：文章以nRF24LE1射频收发芯片为控制器,设计了一种基于温度补偿超声波测距技术及射频无线数据传输技术的导盲系统。系统采用低功耗设计,通过置于双足及腰部的超声波模块对路况进行采集,返回控制器对路况进行分析计算,通过语音模块作出相应的提醒,引导盲人行走。Taking the nRF24LE1 RF transceiver chip as the controller, The artide designed a smart guide system for blind- ness which is based on ultrasonic distance measure technology with temperature compensation. The system adopts the de- sign of low power consumption. To collect the road condition through the ultrasonic sensors on feet and the waist, the con- troller analyzes and takes different road conditions into consideration. The voice module triggers sounds to remind, guid- ing the blind person to walk.
