参加重庆市“盛群杯”大学生单片机设计竞赛，设计基于超声波测距的多功能智能导盲杖。导盲症以HT46R24为核心，用超声波传感器自动检测障碍物，用语音和震动两种方式提示盲人壁障。还带有实时时钟语音报时、整点报时、闹钟等，已经按键手动调整时间、闹钟等人性化功能。-Participate in Chongqing "Holtek Cup" college microcontroller design contest, design multifunctional smart guide cane-based ultrasonic ranging. HT46R24 lead to blindness as the core, with automatic ultrasonic sensors detect obstacles, and vibration are two ways to use voice prompts blind barrier. Also with real-time clock voice broadcast, the whole point timekeeping, alarm clock, etc., have been the keys to manually adjust the time, alarm and other user-friendly features.
