基于模糊逻辑与数据融合的智能导盲手杖

An Intelligent Blind-guiding Cane on Fuzzy Logic and Data Fusion

在分析国内外现有导盲设备的基础上,引入模糊逻辑与数据融合算法,对传统超声波探测方式进行改进。自行设计并组建超声波障碍物探测网络,进行数据采集、融合与分析,实现了对障碍物方位与距离的综合探测。此外,利用GPS模组、网络通信技术以及语音合成芯片设计,并实现了智能导盲手杖的GPS位置信息实时获取、GPRS短信提示、蓝牙语音提示等功能,以满足盲人日常生活的需求。

On the basis of analyzing the domestic and abroad existing blind - guiding equipment, the traditional ultrasonic detection algorithm is improved by introducing the fuzzy logic and data fusion algorithm. An ultrasonic ob- stacle detection network is designed and built for data collection, fusing and analysis, capable of comprehensive de- tection of the obstacle orientation and distance. The GPS module, online communication technology and speech syn- thesis chip are employed to achieve a series of functions, such the real - time GPS location acquisition, GPRS SMS prompts and Bluetooth voice prompts, to meet various needs of the blinds in their everyday life.
