摘要
基于我国盲人及视力障碍者数量大,行动不便,设计导盲杖用于识别路况,有助于盲人日常生活。应用嵌入式技术和超声波技术设计导盲杖,用超声测距模块分别探测正前方、左前方和右前方3个方向的障碍物,用C8051F360单片机获取3个距离信息,并根据处理结果通过语音进行提示;同时,用另一超声波模块对路面情况进行探测,根据距离信息判断路况,并通过语音进行提示。本装置具有障碍物探测及时、路面情况探测准确、成本低、可靠性高、操作方便的特点,可为盲人行走提供安全保障。
China has a great number of blind men or man with visual disturbance, which bring inconvenient. Designing a blind guiding crutch that can identify road conditions can benefit those people. Apply embedded and ultrasonic technology to design the blind guiding crutch. Use ultrasonic sensors to detect obstacles in three directions, dead ahead, left anterior and fight anterior. The three distances data are transferred to single chip C8051F360, which will give out voice prompt based on its analyzing results on the distance data. Meanwhile, another ultrasonic detects road condition by providing distance data to the single chip, which will also give out voice prompL This device has characteristics of detecting obstacles in time, detecting road conditions correctly, low cost, high reliability, convenient operations, which can provide safe guarantee for the blind walking.
