Blind-guide stick, blind-guide system and blind-guide method

Abstract

The invention provides a blind-guide stick, a blind-guide system and a blind-guide method. The blind-guide stick comprises a switch, a handle, a supporting rod, an input device, a main control system,an obstacle avoidance system, a navigation information obtaining device and a fall-over protection system. The blind-guide system comprises tag information and satellite signal geographic position information corresponding to a radio frequency identification tag, an intelligent user terminal and the blind-guide stick. The blind-guide method comprises the steps that by using the blind-guide stick,the current geographic position information of a user is obtained, and a user request information is received; the current geographic position information of the user and the user request informationare sent to the blind-guide stick; the blind-guide stick plans a path according to the received information, and navigation information is generated to conduct navigation. The blind-guide stick can provide more accurate navigation information for the user, and the coverage range is wide; when the user goes out, the road condition information can be fed back to the user in real time, and the userinformation is fed back to other people in real time; the blind-guide system is complete in function, low in cost and high in feasibility; the blind-guide method is high in response speed, safe and convenient to use.
