Abstract
The utility model discloses a navigator for blind persons, which comprises a host machine and a receiving earphone. The host machine is provided with an ultrasonic echo sounding device, a data processing chip of the echo sounding device, function keys with braille and a USB data interface, and the receiving earphone is a Bluetooth earphone. The navigator can guide blind persons to reach destinations through an intelligent voice system, timely prompts front corners for the blind persons during walking, and simultaneously tells passed typical buildings such as stores and the like for the blind persons. In addition, the blind persons can record and position frequented places and routes in the navigator, thereby bringing convenience for going out next time.
Description
Technical field
The utility model relates to a kind of blind person navigating instrument of going on a journey, and main blind man colony uses.
Background technology
In the life, a lot of blind persons reflect that the difficulty that the blind person goes on a journey is that common people are unthinkable.Though along with the development of material and spiritual civilization, society also more and more pays close attention to the animation of blind person colony, such as setting up the sidewalk for visually impaired people, the training seeing-eye dog organizes that the blind person carries out that orientation walking is trained etc., still can't fully solve blind person's difficult problem of going on a journey.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that overcomes above-mentioned existing blind man navigation instrument, provides a kind of blind person of allowing can walk in streets and lanes independently, easily, enjoys the blind man navigation instrument with the same life of healthy people.
The technical solution adopted in the utility model is: a kind of blind man navigation instrument, comprise main frame and receive earphone, described main frame is provided with the data processing chip of ultrasound wave reflection sounding device, reflection sounding device, the function button and the usb data interface of band braille, and described reception earphone is a bluetooth earphone.
The utility model can pass through intelligent voice system, for the blind person guides the route that arrives the destination, in traveling process in time prompting the place ahead turn round, corner, tell the representative buildings such as shop that the user passes by simultaneously.In addition, the blind person can write down the place route that often goes in the life of location oneself in navigating instrument, convenient trip next time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1-2, the implementation case comprises: main frame 1 and reception earphone 2, main frame 1 be provided with ultrasound wave reflection sounding device, reflection sounding device data processing chip 4, make things convenient for the band braille that the blind person uses function button 3, charging and have the usb data interface 5 of dust cap 6 is used to communicate by letter, receiving earphone 2 is bluetooth earphone 2, be used for roadblock information is told to the blind person by sound, allow the blind person do due processing.Main frame 1 also is provided with the data-carrier store that is connected with data processing chip 8, data-carrier store is used for writing down the blind person at the place route of oneself living and often going, convenient trip next time, data-carrier store can be communicated by letter with extraneous by usb data interface 5 in addition, is used to store the information of strange route.
Main frame 1 integral body can be designed to streamlined one, and the bottom is provided with anti-skidding line 7, adopts working of plastics global formation technology, meets ergonomics, holds comfortablely, makes things convenient for the blind person.Bluetooth earphone 2 is small and exquisite slim and graceful, is convenient for carrying.
The blind person is by pressing function key 3, control ultrasound wave reflection sounding device, data processing chip 4 detects information processing with the reflection sounding device and becomes voice messaging to send to bluetooth earphone 2, and bluetooth earphone 2 is with voice messaging high speed blind person, thereby the blind person learns road information.
