Abstract

The utility model relates to a navigation blind stick, which comprises a hand lever and a stick rod, wherein the hand lever is provided with a speaker, a radar detection window and a bar code identification window; the stick rod is provided with a traffic light identification window and a luminescence window, and the lower end surface of the stick rod is provided with a suction disc, and a radar distance measuring module, a traffic light identification module, a bar code identification module, a sound production module, a GPS module, a luminescence module and a central control module are arranged inside the blind stick, and the radar distance measuring module, the traffic light identification module, the bar code identification module, the sound production module, the GPS module and the luminescence module are connected with the central control module through a special interface. Different modules of the navigation blind stick have different functions and are convenient for the blind people to go out or to work.

Description

The navigation blind man's stick

Technical field

This utility model relates to a kind of blind man's stick of the articles for daily use, especially a kind of navigation blind man's stick.

Background technology

The blind person has the people who contains the reason defective, their action has inconvenience, can't judge barrier on the road and pedestrians' problem when trotting out, the problem of traffic signal light condition can't be learnt when crossing the crossroad in addition, problem can't be determined whether when and for example going to some place into its destination.At present the sidewalk for visually impaired people can be set during municipal construction on footpath, but its course of blind person can only be informed in the sidewalk for visually impaired people, but can't make blind person's avoiding obstacles and pedestrian, though and the blind person can be by hearing the mode of asking need go to some place the time, but the blind person can't look thing after all, is very inconvenient, especially when passing through the crossroad, because blind person's physiological defect causes its state and the road conditions that can not learn signal lights as the normal person, cause getting into an accident easily like this.Because the blind person can't use eyes, and the maximum instrument that uses at ordinary times is exactly a blind man's stick, assists blind persons to obtain information will to greatly facilitate the blind person if some auxiliary instruments can be set in blind man's stick.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, and Pasting is at any one vehicles, and can change the billboard of the replaceable content in content ground easily.

The technical scheme that this utility model is taked is:

A kind of navigation blind man's stick, comprise handle and cane bar, it is characterized in that: handle is provided with speaker, radar detection window and bar-code identification window, the cane bar is provided with the traffic light identification window, luminescence window, cane bar lower surface is equipped with sucker, the radar range finding module is installed in the blind man's stick, the traffic light identification module, the bar-code identification module, the sounding module, the GPS module, light emitting module and central control module, the radar range finding module, the traffic light identification module, the bar-code identification module, the sounding module, the GPS module, light emitting module all connects central control module by special purpose interface.

And described radar range finding module is reported according to the distance of reflected impulse dyscalculia thing and by the sounding module.

And described traffic light identification module drives the sounding module according to detected traffic lights signal and reports.

And described bar-code identification module drives the sounding module by the bar code on each place Sign Board of identification and reports.

And described light emitting module utilizes infrared detecting unit to detect the interior moving heat source automatic interrupter infrared illumination lamp of certain limit.

Advantage of the present utility model and good effect are:

1. the radar range finding module of this utility model installation utilizes radio-wave reflection to determine whether the place ahead has barrier, and sounding prompting blind person slows down gait of march or changes direct of travel then.

2. the traffic light identification module installed of this utility model comes the state of marker lamp by the different wave length to red, yellow, green three kinds of light, points out the blind person to note traffic safety by sounding.

3. the bar-code identification module of this utility model installation is discerned the bar code on the notice board of place and is informed blind person place physical location by sound-producing device.

4. the light emitting module installed of this utility model is opened the infrared illumination lamp at night when dark, simultaneously the thermal source in the certain limit is discerned.

5. this utility model GPS module of installing changes visual signal into audible signal and advances to instruct the blind person.

6. the sucker installed of this utility model can be firm on bus is adsorbed on ground, guarantees blind person's safety.
