新型智能导盲拐杖的设计

Design of a New Intelligent Guide Crutch

针对于盲人在实际中行走困难的问题,设计基于51单片机系统的智能导盲拐杖。该拐杖主要以51单片机为处理器,利用超声波模块测试有无障碍物,使单片机驱动语音、光照、振动等模块发出相应的提醒,以此来达到提醒盲人在实际中避障的效果。此外,该系统采用双超声波模块,成功地解决避让类似台阶一类的障碍物。在实际中的测试结果表明:此智能拐杖能够达到预期的效果,而且制造成本低、携带方便。

Aiming at the problem of blind walking difficulties in practice, designs the intelligent guide blind crutch based on 51 single chip microcomputer system. The crutch is mainly based on 51 single chip microcomputer processor, uses the ultrasonic module test with and without obstacles, makes SCM drive voice, light, vibration and so on module corresponding to remind, in order to achieve to remind the blind in the actual effect of obstacle avoidance. In addition, the system adopts the dual ultrasonic module, which successfully solves the obstacles such as the steps. The actual test results show that this intelligent crutch can achieve the desired effect, and the manufacturing cost is low and easy to carry.
