Abstract

The invention discloses a blind guiding system. The system comprises a voice recognition module, a radio frequency identification module, a main control module and a voice processing module, wherein the voice recognition module is used for receiving voice information containing a destination address; the radio frequency identification module is used for identifying address information preset in a radio frequency identification tag on a blind way; the main control module is used for matching route information for a user according to the destination address in the voice information and the address information in the radio frequency identification tag; and the voice processing module is used for outputting matched route information to the user through voice. The embodiment of the invention can provide guidance for the blind more conveniently and enables the blind user to avoid walking for more distance and meeting with barriers so as to reach a destination rapidly.

Description

technical field [0001] The invention belongs to the technical field of automatic detection and control. Specifically, it relates to a system for guiding the blind in a family room by using technologies such as radio frequency identification and speech synthesis. Background technique [0002] Most of the information in people's life is obtained through vision, and blind people lose their vision, which brings a lot of inconvenience to their work, life and study. Therefore, the blind person needs the assistance of a blind guide device when walking alone. Among them, the simplest and most commonly used device is the blind stick, which is used to judge the terrain of the passing position and whether it is dangerous by tapping the ground. Later, the electronic blind stick appeared, which uses infrared sensing electronic technology and ultrasonic technology to extend the detection time range, but the range they can perceive is very limited, and they cannot yet play a guiding role...
