摘要
文章设计了一种基于超声波测距原理的导盲系统。系统以STC125A60S2单片机为核心控制器件,利用渡越时间法测量经温度传感器DB18B-20补偿后的距离,实现对盲人行走道路上障碍物距离的测量及定位,并通过SYN6658语音模块进行语音播报导航。
In this paper, a blind-aid system based on the principle of ultrasonic ranging is designed. In the system the STC12C5A60S2 MCU is used as the core control device, and the distance compensated by temperature sensor DB18B-20 which is measured using transit time method is used to realize the distance measurement and location of the obstacles on the road ahead for the blind, and the speech navigation is realized with SYN6658 voice module.
