Abstract
The utility model discloses a positioning sounding crutch for the blind. The crutch for the blind is respectively internally provided with a GPS global positioning system and an ultrasonic distance measurer. The output ends of the GPS global positioning system and the ultrasonic distance measurer are respectively connected with two signal input ends of a control chip. The output end of the control chip is connected with a voice broadcasting device. The operation input end of the control chip is a button carved with braille. When a user encounters a barrier or is in a place without a blind road, the user starts up the ultrasonic distance measurer by the button carved with the braille and determines how far is the barrier from the user by sending an ultrasonic wave; and when the user needs to know about a specific position thereof, the user starts up the GPS global positioning system by the button carved with the braille, the GPS global positioning system measures information of the specific position of the user, and the voice broadcasting device informs the user about the information.
Description
Technical field
This utility model relates to a kind of blind person and uses crutch, and particularly a kind of orientable sounding blind person uses crutch.
Background technology
The blind person is that the blind person is used for the important tool of perception surrounding with crutch, but run into barrier or do not have the sidewalk for visually impaired people local time trouble just appears.Perfect along with modern navigation system, if can with around positional information be converted into voice messaging and convey to the blind person, just make the environment of blind person around can better understanding, make better judgement.
The utility model content
The purpose of this utility model is to provide a kind of orientable sounding blind person to use crutch, the blind person with crutch on respectively built-in GPS global location instrument and ultrasonic distance measuring apparatus, the outfan of GPS global location instrument and ultrasonic distance measuring apparatus is connected with two signal input parts of control chip respectively, the outfan of control chip is connected with voice announcer, and the operation input of control chip is the button that is carved with braille.
When the user run into barrier or do not have the sidewalk for visually impaired people local time, start ultrasonic distance measuring apparatus by the button that is carved with braille, determine barrier in addition how far by forwards sending ultrasound wave from oneself, voice broadcasting system is with this information notification user; When obstacle distance change, when removable, the user can press button by prompting and " would you please allow! ", be that this is an immovable obstruction if barrier does not move, then can press another cue button and " would you please help me! ", come plea for aid.
When the user need understand concrete residing position, start GPS global location instrument by the button that is carved with braille, GPS global location instrument is measured the information of place particular location, and voice broadcasting system is with this information notification user; Every like this place, the user can know own on what building next door; When if user's household need seek simultaneously, also can know the position at user place accurately.
Description of drawings
Fig. 1 is a connection diagram of the present utility model.
Below in conjunction with accompanying drawing this utility model is elaborated.
The specific embodiment
Referring to Fig. 1, this utility model is used crutch in the orientable sounding blind person who provides, the blind person with crutch on respectively built-in GPS global location instrument and ultrasonic distance measuring apparatus, the outfan of GPS global location instrument and ultrasonic distance measuring apparatus is connected with two signal input parts of control chip respectively, the outfan of control chip is connected with voice announcer, and the operation input of control chip is the button that is carved with braille;
Orientable sounding blind person adopts alloy with the main body of crutch, in light weight again can proof strength; GPS global location instrument and ultrasonic distance measuring apparatus are integrated on the main body of crutch, control chip be arranged on the default draw-in groove after voice announcer is connected, be entrenched in the body surfaces of crutch as the button that is carved with braille of control end, user-friendly.
When the user run into barrier or do not have the sidewalk for visually impaired people local time, start ultrasonic distance measuring apparatus by the button that is carved with braille, determine barrier in addition how far by forwards sending ultrasound wave from oneself, voice broadcasting system is with this information notification user; When obstacle distance change, when removable, the user can press button by prompting and " would you please allow! ", be that this is an immovable obstruction if barrier does not move, then can press another cue button and " would you please help me! ", come plea for aid.
When the user need understand concrete residing position, start GPS global location instrument by the button that is carved with braille, GPS global location instrument is measured the information of place particular location, and voice broadcasting system is with this information notification user; Every like this place, the user can know own on what building next door; When if user's household need seek simultaneously, also can know the position at user place accurately.
