Abstract：Objective To design a guide system based on ultrasonic sensor array to solve the inconvenience and safety problems for the travel of people with visual impairment. Methods Based on the ultrasonic sensor TCT40-16T/R, the hardware of the system was designed with single-chip microcomputer AT89S52 as its control and data processing core. C language was used to design the program of the system and MATLAB was used to design the software of the system. Results The system can detect obstacles accurately (including distance and direction), and enjoys the advantages of high detection accuracy and wide detection range. Conclusion The system will play an important role in solving the travel difficulties for people with visual impairment.
