【摘要】 为了方便盲人朋友出行,提出了一种基于STC90C516RD单片机的多功能盲人智能拐杖设计方案,并完成了系统的软硬件设计。整个系统采用模块化设计,由测距模块、电子指南模块、时钟显示模块、GSM通信模块、语音播报等模块组成,实现了报时、紧急呼救、方位辨识和障碍探测等功能,并且所有功能均伴有语音提示。为了使设计更加人性化,该系统设置了功能按键,使用者可以通过按键实现各个功能之间的切换。实际应用结果表明,智能拐杖不但克服了传统拐杖的缺点,而且使用简单,能够为盲人朋友提供更加便捷、安全的出行方式。更多还原

【Abstract】 In order to facilitate the walk of the blind, the design of the multifunctional smart cane for the blind based on stc90c516 rd single chip microprocessor is proposed in this paper, and hardware and software system is also completed. The whole system adopts modular design, and the cane is composed by ranging module, electronic compass module, clock display module, GSM communication module, voice broadcasting module and other modules, and the functions of telling time, asking for help, recognizing direction and detecting obstacles are accomplished, at the same time, all functions are associated with voice prompt. The switch between each function was achieved by buttons set in system so as to make the design more humanized. The experiment and application show that smart cane not only overcomes shortcuts of traditional cane, but also uses easily, it can offer a trip way of safe and convenient.更多还原
