Abstract:

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 obstacle detection network is designed and built for data collection, fusing and analysis, capable of comprehensive detection of the obstacle orientation and distance. The GPS module, online communication technology and speech synthesis 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.

Key words: obstacle detection network, fuzzy logic, data fusion, real-time location getting, voice prompts by Bluetooth
