摘　　要：盲人在独自行走时主要依靠导盲装置.文章提出了一种基于AT89C51单片机为控制核心,辅以ISD4004语音芯片和失心电机,利用超声波测距原理设计了一种智能手杖.该装置可以对障碍物进行距离探测并转换成语音提示,同时发出振动报警.具有测量精度较高,易于调试,成本低廉等特点.The blind persons depend mainly on guiding installment for them when walking alone. A intelligent walking stick has been put forward in this article. Which based on AT89C51 chip microcomputer as controlling centre,additional to ISD4004 speech chip and the shaking elec- tric engine, using ultrasonic ranging principle to design. The equipment can detect the distance from the obstacle and shift this into voice prompt, simultaneously send out vibration alarm. Its characteristics are as follows：low cost, utility and precision.
