路口导盲及马路障碍物检测提醒系统的设计

为了帮助盲人自行通过路口并检测提醒盲人道路上的障碍物情况，设计制作了一个路口导盲及马路障碍物检测提醒系统，该系统通过超声波模块检测障碍物信息，通过方向传感器模块和无线通信模块获取盲人的朝向信息和盲人当前朝向路口的红绿灯信息，并利用震动模块和语音模块对盲人进行提醒。最后制作出系统实物并模拟验证了该系统是有效可行的。

Design of Crossing Guide and Road Obstacle Detection and Warning System

In order to help blind people themselves through the intersection and to detect obstacles on the road and to remind the blind,a road intersection guide and obstacle detection reminder system is designed.The system detects obstacles information by the ultrasonic module.The direction information of the blind and the traffic signal of the blind toward the intersection are obtained by the direction sensor module and the wireless communication module.The motion module and the voice module are used to call attention to the blind.Finally,the system is produced and simulated to verify that the system is effective and feasible.
