摘　　要：针对目前城市盲道主要采用盲人脚底感觉区别盲道来引导盲人出行中存在的一些问题,设计一种新型的基于敷设钕铁硼磁铁的盲道和手持探测棒系统,给出详细的设计原理图及方法。该系统的盲道与现有的盲道不同,它将原有的盲道敷设的地面砖换成具有磁性材料的地面砖,使用单片机、磁性传感器系统和蓝牙模块构成的磁性探测棒进行探测,具有磁性检测灵敏度、提示音量可调节等优点,并可以通过蓝牙模块,配合基于百度地图开发的盲人手机的导航APP,语音提示当前的地理位置,也可以通过探测棒上的蜂鸣器提示是否行走在盲人道内,极大地方便了盲人的出行。该系统设计构造简单、使用方便,通过实际测试和实验,达到了最初的设计目的。In allusion to the problems existing in the current outgoing guidance of blind people who discriminate blind lanes in cities by relying on feeling of their feet,a new system of blind lane based on laying of neodymium magnets and handheld detection bar is designed. The detailed diagram and method of the design principle are given. The blind lane of the system is different from the current blind lane. The original ground bricks laid on blind lanes are substituted by the ground bricks with magnetic materials. The magnetic detection bar composed of the SCM,magnetic sensor system and Bluetooth module is used for detection,which has the advantages of sensitive magnetic detection and adjustable beep volume. Voice prompt of the current geographic position can be realized by using the Bluetooth module matched with blind people ′ s navigational mobile APP developed based on the Baidu map. The blind people can be reminded whether they are on the blind lane via the buzzer on the detection bar,which greatly facilitates the outgoing of blind people. The system has simple design construction,and is easy to use. The actual test and experiment show that the system has achieved the initial design purpose.
