导盲系统的设计及实现

目前多数的视力患者通过使用盲人杖来辅助独立行走,但盲人杖的功能单一,且存在诸多安全隐患,针对以上问题文中提出的导盲系统在普通盲人手杖的基础上,利用红外测距原理,识别周围是否有物体,利用语音播报模块发出语音信号提示,利用温度传感器感应盲人手心位置温度变化辅助盲人找回导盲杖,通过GPS定位系统,有效地防止盲人走失,实现对盲...

Design and Implementation of guidance system for blind people

At present,most vision patients use blind stick to assist independent walking,but the functions of blindstick is single,and there are manypotentialsecurityrisks.In response to the above problems,the system for assisting blind people proposed in this pa?per uses the principle of infrared distance measurement based on the ordinary blind cane to identify whether there are objects around,uses the voice broadcast module to send out voice signal prompts,and uses a temperature sensor to sense the temperature change of the blind person's palm to assist the blind people in finding stick,through the GPS positioning system,effectively pre?vents the blindperson from getting lost,realizes real-time monitoring of the position of the blind people,and effectively solves the problem of independent and safe travel of the blind people.
