Wireless voice blind guide system

Abstract

The invention provides a wireless voice blind guide system, which consists of a blind guide terminal 1 and a blind guide access point 2. The blind guide terminal 1 is provided with an uplink module 1a, a downlink module 1b, a control module 1c, a voice output module 1d, a vibration output module 1e and a bone conduction or air conduction earphone; and the blind guide access point 2 is provided with an uplink module 2a, a downlink module 2b, a control module 2c, a voice storage module 2d and an other information module 2e. The blind guide terminal 1 and the blind guide access point 2 form a communication mechanism for an uplink and a downlink, and the blind guide access point 2 can automatically carry out voice navigation on a blind person when the blind person enters a blind guide area with the blind guide terminal 1; and voices are transmitted to the blind person through the bone conduction or air conduction earphone, so that the privacy of the blind person is protected, and meanwhile, the noise influence on the environment cannot be caused.

Description

technical field [0001] The present invention relates to a wireless voice guidance system for the blind. Background technique [0002] With the continuous improvement of economic development and social civilization, solving the problem of blind people's activities in public areas has attracted more and more attention and attention. Many institutions have developed tools such as guide sticks with speakers, blind glasses to detect obstacles ahead, and RFID-based indoor navigation systems. However, guide sticks and glasses for the blind can only simply detect obstacles ahead to help the blind walk, while the indoor navigation system based on RFID needs to make close contact between RFID and the navigation system to be effective. [0003] The regional navigation system based on RFID voice service adopts the mechanism of radio frequency to provide identification service. In recent years, it has been widely used in security protection, commodity production and sales, management a...

AI Technical Summary

Problems solved by technology

[0007] 1. The resolution of the GIS database information system matched with the GPS positioning system is not high, and its accuracy is only suitable for normal people, and it cannot meet the high-resolution requirements of the blind at present.

[0008] 2. The manual input method of human-computer interaction is only suitable for normal people, and it cannot meet the functional needs of blind people.
