中文摘要：

设计了一个基于物联网的盲人智能手杖，手杖采用超声波、红外避障、热释感应传感器检测行人和障碍物，用蓝牙语音和振动进行避障提醒，用GPS、GSM完成用户定位和呼救信息的报送。给出了手杖以及呼救中心的整体方案和软、硬件设计。并对手杖的避障、蓝牙通信、语音播报、振动提示、定位、短信发送和呼救中心等各项功能进行了测试。该设计能够实现盲人用户的行路引导、呼救信息报送和响应处理，具有一定应用推广价值。

英文摘要：

A blind man smart cane based on IOT is designed in this paper. In this design, ultrasonic, infrared and pyroeleetric in- duction sensors are used to detect pedestrians or obstructions while w~ice and vibration are used to warn the user. GPS and GSM are used to location and send the calling information. Design and test of the hardware and software of the cane and calling center are shown. This design can be used as a guide and help calling tool with good application value.
